An indicator framework for the monitoring and evaluation of event-based surveillance systems
Crawley AW , Mercy K , Shivji S , Lofgren H , Trowbridge D , Manthey C , Tebeje YK , Clara AW , Landry K , Salyer SJ . Lancet Glob Health 2024 Event-based surveillance (EBS) systems have been implemented globally to support early warning surveillance across human, animal, and environmental health in diverse settings, including at the community level, within health facilities, at border points of entry, and through media monitoring of internet-based sources. EBS systems should be evaluated periodically to ensure that they meet the objectives related to the early detection of health threats and to identify areas for improvement in the quality, efficiency, and usefulness of the systems. However, to date, there has been no comprehensive framework to guide the monitoring and evaluation of EBS systems; this absence of standardisation has hindered progress in the field. The Africa Centres for Disease Control and Prevention and US Centers for Disease Control and Prevention have collaborated to develop an EBS monitoring and evaluation indicator framework, adaptable to specific country contexts, that uses measures relating to input, activity, output, outcome, and impact to map the processes and expected results of EBS systems. Through the implementation and continued refinement of these indicators, countries can ensure the early detection of health threats and improve their ability to measure and describe the impacts of EBS systems, thus filling the current evidence gap regarding their effectiveness. |
Advanced child tax credit payments and national child abuse hotline contacts, 2019-2022
Merrill-Francis M , Chen MS , Dunphy C , Swedo EA , Zhang Kudon H , Metzler M , Mercy JA , Zhang X , Rogers TM , Wu Shortt J . Inj Prev 2024 BACKGROUND: Children in households experiencing poverty are disproportionately exposed to maltreatment. Income support policies have been associated with reductions in child abuse and neglect. The advance child tax credit (CTC) payments may reduce child maltreatment by improving the economic security of some families. No national studies have examined the association between advance CTC payments and child abuse and neglect. This study examines the association between the advance CTC payments and child abuse and neglect-related contacts to the Childhelp National Child Abuse Hotline. METHODS: A time series study of contacts to the Childhelp National Child Abuse Hotline between January 2019 and December 2022 was used to examine the association between the payments and hotline contacts. An interrupted time series (ITS) exploiting the variation in the advance CTC payments was estimated using fixed effects. RESULTS: The CTC advance payments were associated with an immediate 13.8% (95% CI -17.5% to -10.0%) decrease in contacts to the hotline in the ITS model. Following the expiration of the advance CTC payments, there was a significant and gradual 0.1% (95% CI +0.0% to +0.2%) daily increase in contacts. Sensitivity analyses found significant reductions in contacts following each payment, however, the reductions were associated with the last three of the six total payments. CONCLUSION: These findings suggest the advance CTC payments may reduce child abuse and neglect-related hotline contacts and continue to build the evidence base for associations between income-support policies and reductions in child abuse and neglect. |
Economic burden of health conditions associated with adverse childhood experiences among US adults
Peterson C , Aslam MV , Niolon PH , Bacon S , Bellis MA , Mercy JA , Florence C . JAMA Netw Open 2023 6 (12) e2346323 IMPORTANCE: Adverse childhood experiences (ACEs) are preventable, potentially traumatic events in childhood, such as experiencing abuse or neglect, witnessing violence, or living in a household with substance use disorder, mental health problems, or instability from parental separation or incarceration. Adults who had ACEs have more harmful risk behaviors and worse health outcomes; the economic burden associated with these issues is uncertain. OBJECTIVE: To estimate the economic burden of ACE-associated health conditions among US adults. DESIGN, SETTING, AND PARTICIPANTS: In this economic evaluation, regression models of cross-sectional survey data from the 2019-2020 Behavioral Risk Factor Surveillance System (BRFSS) and previous studies were used to estimate ACE population-attributable fractions (PAFs) (ie, the fraction of total cases associated with a specific exposure) for selected health outcomes (anxiety, arthritis, asthma, cancer, chronic obstructive pulmonary disease, depression, diabetes, heart disease, kidney disease, stroke, and violence) and risk factors (heavy drinking, illicit drug use, overweight and obesity, and smoking) among the 2019 US adult population. Adverse childhood experience PAFs were used to calculate the proportion of total condition-specific medical spending and lost healthy life-years related to ACEs using Global Burden of Disease Study data. Data analysis was performed from September 10, 2021, to November 29, 2022. EXPOSURE: Adverse childhood experiences (age <18 years). MAIN OUTCOMES AND MEASURES: Monetary valuation of ACE-associated morbidity and mortality using standard US value of statistical life methods and presented in terms of annual and lifetime per affected person and total population estimates at the national and state levels. RESULTS: A total of 820 673 adults, representing 255 million individuals, participated in the BRFSS in 2019 and 2020. An estimated 160 million of the total 255 million US adult population (63%) had 1 or more ACE, associated with an annual economic burden of $14.1 trillion ($183 billion in direct medical spending and $13.9 trillion in lost healthy life-years). This was $88 000 per affected adult annually and $2.4 million over their lifetimes. The lifetime economic burden per affected adult was lowest in North Dakota ($1.3 million) and highest in Arkansas ($4.3 million). Twenty-two percent of adults had 4 or more ACEs and comprised 58% of the total economic burden-the estimated per person lifetime economic burden for those adults was $4.0 million. CONCLUSIONS AND RELEVANCE: In this cross-sectional analysis of the US adult population, the economic burden of ACE-related health conditions was substantial. The findings suggest that measuring the economic burden of ACEs can support decision-making about investing in strategies to improve population health. |
Costs of fatal and nonfatal firearm injuries in the U.S., 2019 and 2020
Miller GF , Barnett SBL , Florence CS , McDavid Harrison K , Dahlberg LL , Mercy JA . Am J Prev Med 2023 INTRODUCTION: Firearm-related injuries are among the five leading causes of death for people aged 1-44 years in the U.S. The immediate and long-term harms of firearm injuries pose an economic burden on society. Fatal and nonfatal firearm injury costs in the U.S. were estimated providing up-to-date economic burden estimates. METHODS: Counts of nonfatal firearm injuries were obtained from the 2019-2020 Healthcare Cost and Utilization Project Nationwide Emergency Department Sample. Data on nonfatal injury intent were obtained from the National Electronic Injury Surveillance System - Firearm Injury Surveillance System. Counts of deaths (firearm as underlying cause) were obtained from the 2019-2020 multiple cause-of-death mortality data from the National Vital Statistics System. Analyses were conducted in 2023. RESULTS: The total nonfatal and fatal cost of firearm-related injuries for 2020 was $493.2 billion. Nonfatal firearm injuries and costs increased by 20% from 2019 to 2020. There are significant disparities in the cost of firearm deaths in 2019-2020, with non-Hispanic Black people, males, and young and middle-aged groups being the most affected. CONCLUSIONS: Most of the nonfatal firearm injury-related costs are attributed to hospitalization. These findings highlight the racial/ethnic differences in fatal firearm injuries and the disproportionate cost burden to urban areas. Addressing this important public health problem can help ameliorate the costs to our society from the rising rates of firearm injuries. |
Prevalence of adverse childhood experiences among U.S. Adults - Behavioral Risk Factor Surveillance System, 2011-2020
Swedo EA , Aslam MV , Dahlberg LL , Niolon PH , Guinn AS , Simon TR , Mercy JA . MMWR Morb Mortal Wkly Rep 2023 72 (26) 707-715 Adverse childhood experiences (ACEs) are defined as preventable, potentially traumatic events that occur among persons aged <18 years and are associated with numerous negative outcomes; data from 25 states indicate that ACEs are common among U.S. adults (1). Disparities in ACEs are often attributable to social and economic environments in which some families live (2,3). Understanding the prevalence of ACEs, stratified by sociodemographic characteristics, is essential to addressing and preventing ACEs and eliminating disparities, but population-level ACEs data collection has been sporadic (1). Using 2011-2020 Behavioral Risk Factor Surveillance System (BRFSS) data, CDC provides estimates of ACEs prevalence among U.S. adults in all 50 states and the District of Columbia, and by key sociodemographic characteristics. Overall, 63.9% of U.S. adults reported at least one ACE; 17.3% reported four or more ACEs. Experiencing four or more ACEs was most common among females (19.2%), adults aged 25-34 years (25.2%), non-Hispanic American Indian or Alaska Native (AI/AN) adults (32.4%), non-Hispanic multiracial adults (31.5%), adults with less than a high school education (20.5%), and those who were unemployed (25.8%) or unable to work (28.8%). Prevalence of experiencing four or more ACEs varied substantially across jurisdictions, from 11.9% (New Jersey) to 22.7% (Oregon). Patterns in prevalence of individual and total number of ACEs varied by jurisdiction and sociodemographic characteristics, reinforcing the importance of jurisdiction and local collection of ACEs data to guide targeted prevention and decrease inequities. CDC has released prevention resources, including Preventing Adverse Childhood Experiences: Leveraging the Best Available Evidence, to help provide jurisdictions and communities with the best available strategies to prevent violence and other ACEs, including guidance on how to implement those strategies for maximum impact (4-6). |
Violent victimization during childhood in the United States: Associations with revictimization and health
Basile KC , Chen J , Smith SG , Clayton HB , Simon TR , Mercy JA . Violence Vict 2023 38 (3) 375-395 Childhood violence victimization is a serious adverse childhood experience with lasting health impacts. This study examined the prevalence and characteristics of five forms of childhood violence victimization and their association with revictimization and negative health conditions among adults. Data are from the 2010-2012 National Intimate Partner and Sexual Violence Survey. Age at first victimization and perpetrator sex were assessed; adjusted odds ratios assessed associations with revictimization and health. Ages 14-17 were the most common age at first victimization for most violence types; almost half of male (46.7%) and a quarter of female (27.0%) rape victims reported first victimization before age 10. Most victimization was associated with revictimization and negative health, controlling for adult victimization. Primary prevention of childhood violence may reduce later health risks. |
Emergency department visits for firearm injuries before and during the COVID-19 pandemic - United States, January 2019-December 2022
Zwald ML , Van Dyke ME , Chen MS , Radhakrishnan L , Holland KM , Simon TR , Dahlberg LL , Friar NW , Sheppard M , Kite-Powell A , Mercy JA . MMWR Morb Mortal Wkly Rep 2023 72 (13) 333-337 During the COVID-19 pandemic, the U.S. firearm homicide rate increased by nearly 35%, and the firearm suicide rate remained high during 2019-2020 (1). Provisional mortality data from the National Vital Statistics System indicate that rates continued to increase in 2021: the rates of firearm homicide and firearm suicide in 2021 were the highest recorded since 1993 and 1990, respectively (2). Firearm injuries treated in emergency departments (EDs), the primary setting for the immediate medical treatment of such injuries, gradually increased during 2018-2019 (3); however, more recent patterns of ED visits for firearm injuries, particularly during the COVID-19 pandemic, are unknown. Using data from the National Syndromic Surveillance Program (NSSP),* CDC examined changes in ED visits for initial firearm injury encounters during January 2019-December 2022, by year, patient sex, and age group. Increases in the overall weekly number of firearm injury ED visits were detected at certain periods during the COVID-19 pandemic. One such period during which there was a gradual increase was March 2020, which coincided with both the declaration of COVID-19 as a national emergency(†) and a pronounced decrease in the total number of ED visits. Another increase in firearm injury ED visits occurred in late May 2020, concurrent with a period marked by public outcry related to social injustice and structural racism (4), changes in state-level COVID-19-specific prevention strategies,(§) decreased engagement in COVID-19 mitigation behaviors (5), and reported increases in some types of crime (4). Compared with 2019, the average number of weekly ED visits for firearm injury was 37% higher in 2020, 36% higher in 2021, and 20% higher in 2022. A comprehensive approach is needed to prevent and respond to firearm injuries in communities, including strategies that engage community and street outreach programs, implement hospital-based violence prevention programs, improve community physical environments, enhance secure storage of firearms, and strengthen social and economic supports. |
Development of a machine learning model to estimate US firearm homicides in near real time
Swedo EA , Alic A , Law RK , Sumner SA , Chen MS , Zwald ML , Van Dyke ME , Bowen DA , Mercy JA . JAMA Netw Open 2023 6 (3) e233413 IMPORTANCE: Firearm homicides are a major public health concern; lack of timely mortality data presents considerable challenges to effective response. Near real-time data sources offer potential for more timely estimation of firearm homicides. OBJECTIVE: To estimate near real-time burden of weekly and annual firearm homicides in the US. DESIGN, SETTING, AND PARTICIPANTS: In this prognostic study, anonymous, longitudinal time series data were obtained from multiple data sources, including Google and YouTube search trends related to firearms (2014-2019), emergency department visits for firearm injuries (National Syndromic Surveillance Program, 2014-2019), emergency medical service activations for firearm-related injuries (biospatial, 2014-2019), and National Domestic Violence Hotline contacts flagged with the keyword firearm (2016-2019). Data analysis was performed from September 2021 to September 2022. MAIN OUTCOMES AND MEASURES: Weekly estimates of US firearm homicides were calculated using a 2-phase pipeline, first fitting optimal machine learning models for each data stream and then combining the best individual models into a stacked ensemble model. Model accuracy was assessed by comparing predictions of firearm homicides in 2019 to actual firearm homicides identified by National Vital Statistics System death certificates. Results were also compared with a SARIMA (seasonal autoregressive integrated moving average) model, a common method to forecast injury mortality. RESULTS: Both individual and ensemble models yielded highly accurate estimates of firearm homicides. Individual models' mean error for weekly estimates of firearm homicides (root mean square error) varied from 24.95 for emergency department visits to 31.29 for SARIMA forecasting. Ensemble models combining data sources had lower weekly mean error and higher annual accuracy than individual data sources: the all-source ensemble model had a weekly root mean square error of 24.46 deaths and full-year accuracy of 99.74%, predicting the total number of firearm homicides in 2019 within 38 deaths for the entire year (compared with 95.48% accuracy and 652 deaths for the SARIMA model). The model decreased the time lag of reporting weekly firearm homicides from 7 to 8 months to approximately 6 weeks. CONCLUSIONS AND RELEVANCE: In this prognostic study of diverse secondary data on machine learning, ensemble modeling produced accurate near real-time estimates of weekly and annual firearm homicides and substantially decreased data source time lags. Ensemble model forecasts can accelerate public health practitioners' and policy makers' ability to respond to unanticipated shifts in firearm homicides. |
How the Global Violence Against Children and Youth surveys help improve pediatric global health
Agathis NT , Annor FB , Mercy J , Chiang L , de Barros RB , Massetti GM . Pediatrics 2022 150 (5) Violence against children is a prevalent, impactful, yet preventable global public health problem. At least half of all children in the world experience violence (physical, sexual, or emotional) every year.1 Aside from its ethical implications and the immediate physical and emotional harm it causes, childhood violence is strongly associated with poor short- and long-term health: increased odds of mental health problems, noncommunicable diseases, sexual and reproductive health problems, health risk behaviors, and experiencing and perpetrating violence in adulthood.2 Childhood violence is also associated with increased risk of HIV acquisition and reduced odds of engagement in HIV clinical prevention services, testing, treatment, and care among youth in high HIV-incidence settings.3–5 |
Health information exchange policy and standards for digital health systems in africa: A systematic review.
Mamuye Adane L , Yilma Tesfahun M , Abdulwahab Ahmad , Broomhead Sean , Zondo Phumzule , Kyeng Mercy , Maeda Justin , Abdulaziz Mohammed , Wuhib Tadesse , Tilahun Binyam C . PLoS Digit Health 2022 10 (10) e0000118 Lack of interoperability and integration between heterogeneous health systems is a big challenge to realize the potential benefits of eHealth. To best move from siloed applications to interoperable eHealth solutions, health information exchange (HIE) policy and standards are necessary to be established. However, there is no comprehensive evidence on the current status of HIE policy and standards on the African continent. Therefore, this paper aimed to systematically review the status of HIE policy and standards which are currently in practice in Africa. A systematic search of the literature was conducted from Medical Literature Analysis and Retrieval System Online (MEDLINE), Scopus, Web of Science, and Excerpta Medica Database (EMBASE), and a total of 32 papers (21 strategic documents and 11 peer-reviewed papers) were selected based on predefined criteria for synthesis. Results revealed that African countries have paid attention to the development, improvement, adoption, and implementation of HIE architecture for interoperability and standards. Synthetic and semantic interoperability standards were identified for the implementation of HIE in Africa. Based on this comprehensive review, we recommend that comprehensive interoperable technical standards should be set at each national level and should be guided by appropriate governance and legal frameworks, data ownership and use agreements, and health data privacy and security guidelines. On top of the policy issues, there is a need to identify a set of standards (health system standards, communication, messaging standards, terminology/vocabulary standards, patient profile standards, privacy and security, and risk assessment) and implement them throughout all levels of the health system. On top of this, we recommend that the Africa Union (AU) and regional bodies provide the necessary human resource and high-level technical support to African countries to implement HIE policy and standards. To realize the full potential of eHealth in the continent, it is recommended that African countries need to have a common HIE policy, interoperable technical standards, and health data privacy and security guidelines. Currently, there is an ongoing effort by the Africa Centres for Disease Control and Prevention (Africa CDC) towards promoting HIE on the continent. A task force has been established from Africa CDC, Health Information Service Provider (HISP) partners, and African and global HIE subject matter experts to provide expertise and guidance in the development of AU policy and standards for HIE. Although the work is still ongoing, the African Union shall continue to support the implementation of HIE policy and standards in the continent. The authors of this review are currently working under the umbrella of the African Union to develop the HIE policy and standard to be endorsed by the head of states of the Africa Union. As a follow-up publication to this, the result will be published in mid-2022. |
Notes from the Field: Increases in Firearm Homicide and Suicide Rates - United States, 2020-2021
Simon TR , Kegler SR , Zwald ML , Chen MS , Mercy JA , Jones CM , Mercado-Crespo MC , Blair JM , Stone DM . MMWR Morb Mortal Wkly Rep 2022 71 (40) 1286-1287 The firearm homicide rate in the United States increased nearly 35% from 2019 to 2020, coinciding with the emergence of the COVID-19 pandemic (1). This increase affected all ages and most population groups, but not equally: existing disparities, including racial and ethnic disparities, widened. The firearm suicide rate was higher than the firearm homicide rate in 2020 and remained consistent with recent years overall; however, increases were observed in some groups (1). To assess potential increases from 2020 to 2021, final 2020 and provisional 2021, National Vital Statistics System mortality data and U.S. Census Bureau population estimates were used to examine all-cause homicide and suicide rates; firearm homicide and suicide rates overall and by sex, age,* race and ethnicity; and the percentage of homicides and suicides from firearm injuries.† This activity was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy.§ |
Centers for disease control and prevention investments in adverse childhood experience prevention efforts
Gervin DW , Holland KM , Ottley PG , Holmes GM , Niolon PH , Mercy JA . Am J Prev Med 2022 62 S1-s5 Lifelong health and well-being are rooted in developmental experiences faced during childhood.1 Adverse childhood experiences (ACEs) are preventable, potentially traumatic events that occur in childhood (age 017 years) such as witnessing or experiencing violence, experiencing neglect, or having a family member attempt or die by suicide. Exposure to ACEs is linked to negative outcomes later in life, including chronic disease; mental health and substance use problems; and even lower education attainment, fewer job opportunities, and decreased earning potential.1, 2, 3, 4, 5 More than 60% of adults report experiencing 1 ACE during childhood, and nearly 1 in 6 adults report experiencing 4 ACEs.6 Recent research suggests that preventing ACEs could potentially reduce millions of cases of heart disease, depression, and other negative health outcomes.6 Given the prevalence of ACEs, their documented impacts on future health and social outcomes, and the potential impacts of prevention efforts, investments in ACE prevention may help to improve public health across the lifespan. |
Vital Signs: Changes in Firearm Homicide and Suicide Rates - United States, 2019-2020.
Kegler SR , Simon TR , Zwald ML , Chen MS , Mercy JA , Jones CM , Mercado-Crespo MC , Blair JM , Stone DM , Ottley PG , Dills J . MMWR Morb Mortal Wkly Rep 2022 71 (19) 656-663 INTRODUCTION: The majority of homicides (79%) and suicides (53%) in the United States involved a firearm in 2020. High firearm homicide and suicide rates and corresponding inequities by race and ethnicity and poverty level represent important public health concerns. This study examined changes in firearm homicide and firearm suicide rates coinciding with the emergence of the COVID-19 pandemic in 2020. METHODS: National vital statistics and population data were integrated with urbanization and poverty measures at the county level. Population-based firearm homicide and suicide rates were examined by age, sex, race and ethnicity, geographic area, level of urbanization, and level of poverty. RESULTS: From 2019 to 2020, the overall firearm homicide rate increased 34.6%, from 4.6 to 6.1 per 100,000 persons. The largest increases occurred among non-Hispanic Black or African American males aged 10-44 years and non-Hispanic American Indian or Alaska Native (AI/AN) males aged 25-44 years. Rates of firearm homicide were lowest and increased least at the lowest poverty level and were higher and showed larger increases at higher poverty levels. The overall firearm suicide rate remained relatively unchanged from 2019 to 2020 (7.9 to 8.1); however, in some populations, including AI/AN males aged 10-44 years, rates did increase. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: During the COVID-19 pandemic, the firearm homicide rate in the United States reached its highest level since 1994, with substantial increases among several population subgroups. These increases have widened disparities in rates by race and ethnicity and poverty level. Several increases in firearm suicide rates were also observed. Implementation of comprehensive strategies employing proven approaches that address underlying economic, physical, and social conditions contributing to the risks for violence and suicide is urgently needed to reduce these rates and disparities. |
Using the Centers for Disease Control and Prevention's National Syndromic Surveillance Program data to monitor trends in US emergency department visits for firearm injuries, 2018 to 2019
Zwald ML , Holland KM , Bowen DA , Simon TR , Dahlberg LL , Stein Z , Idaikkadar N , Mercy JA . Ann Emerg Med 2022 79 (5) 465-473 STUDY OBJECTIVE: We describe trends in emergency department (ED) visits for initial firearm injury encounters in the United States. METHODS: Using data from the Centers for Disease Control and Prevention's National Syndromic Surveillance Program, we analyzed monthly and yearly trends in ED visit rates involving a firearm injury (calculated as the number of firearm injury-related ED visits divided by the total number of ED visits for each month and multiplied by 100,000) by sex-specific age group and US region from 2018 to 2019 and conducted Joinpoint regression to detect trend significance. RESULTS: Among approximately 215 million ED visits captured in the National Syndromic Surveillance Program from January 2018 to December 2019, 132,767 involved a firearm injury (61.6 per 100,000 ED visits). Among males, rates of firearm injury-related ED visits significantly increased for all age groups between 15 and 64 years during the study period. Among females, rates of firearm injury-related ED visits significantly increased for all age groups between 15 and 54 years during the study period. By region, rates significantly changed in the northeast, southeast, and southwest for males and females during the study period. CONCLUSION: These analyses highlight a novel data source for monitoring trends in ED visits for firearm injuries. With increased and effective use of state and local syndromic surveillance data, in addition to improvements to firearm injury syndrome definitions by intent, public health professionals could better detect unusual patterns of firearm injuries across the United States for improved prevention and tailored response efforts. |
Firearm Homicides and Suicides in Major Metropolitan Areas - United States, 2015-2016 and 2018-2019
Kegler SR , Stone DM , Mercy JA , Dahlberg LL . MMWR Morb Mortal Wkly Rep 2022 71 (1) 14-18 Firearm homicides and suicides represent an ongoing public health concern in the United States. During 2018-2019, a total of 28,372 firearm homicides (including 3,612 [13%] among youths and young adults aged 10-19 years [youths]) and 48,372 firearm suicides (including 2,463 [5%] among youths) occurred among U.S. residents (1). This report is the fourth in a series* that provides statistics on firearm homicides and suicides in major metropolitan areas. As with earlier reports, this report provides a special focus on youth violence, including suicide, recognizing the magnitude of the problem and the importance of early prevention efforts. Firearm homicide and suicide rates were calculated for the 50 most populous U.S. metropolitan statistical areas (MSAs)(†) for the periods 2015-2016 and 2018-2019, separated by a transition year (2017), using mortality data from the National Vital Statistics System (NVSS) and population data from the U.S. Census Bureau. Following a period of decreased firearm homicide rates among persons of all ages after 2006-2007 in large metropolitan areas collectively and nationally, by 2015-2016 rates had returned to levels comparable to those observed a decade earlier and remained nearly unchanged as of 2018-2019. Firearm suicide rates among persons aged ≥10 years have continued to increase in large MSAs collectively as well as nationally. Although the youth firearm suicide rate remained much lower than the overall rate, the youth rate nationally also continued to increase, most notably outside of large MSAs. The findings in this report underscore a continued and urgent need for a comprehensive approach to prevention. This includes efforts to prevent firearm homicide and suicide in the first place and support individual persons and communities at increased risk, as well as lessening harms after firearm homicide and suicide have occurred. |
Changes in prevalence of violence and risk factors for violence and HIV among children and young people in Kenya: a comparison of the 2010 and 2019 Kenya Violence Against Children and Youth Surveys
Annor FB , Chiang LF , Oluoch PR , Mang'oli V , Mogaka M , Mwangi M , Ngunjiri A , Obare F , Achia T , Patel P , Massetti GM , Dahlberg LL , Simon TR , Mercy JA . Lancet Glob Health 2021 10 (1) e124-e133 BACKGROUND: Previous research has shown a high prevalence of violence among young people in Kenya. Violence is a known risk factor for HIV acquisition and these two public health issues could be viewed as a syndemic. In 2010, Kenya became the third country to implement the Violence Against Children and Youth Survey (VACS). The study found a high prevalence of violence in the country. Led by the Government of Kenya, stakeholders implemented several prevention and response strategies to reduce violence. In 2019, Kenya implemented a second VACS. This study examines the changes in violence and risk factors for violence and HIV between 2010 and 2019. METHODS: The 2010 and 2019 VACS used a similar sampling approach and measures. Both VACS were cross-sectional national household surveys of young people aged 13-24 years, designed to produce national estimates of physical, sexual, and emotional violence. Prevalence and changes in lifetime experiences of violence and risk factors for violence and HIV were estimated. The VACS uses a three-stage cluster sampling approach with random selection of enumeration areas as the first stage, households as the second stage, and an eligible participant from the selected household as the third stage. The VACS questionnaire contains sections on demographics, risk and protective factors, violence victimisation, violence perpetration, sexual behaviour, HIV testing and services, violence service knowledge and uptake, and health outcomes. For this study, the main outcome variables were violence victimisation, context of violence, and risk factors for violence. All analyses were done with the entire sample of 13-24-year-olds stratified by sex and survey year. FINDINGS: The prevalence of lifetime sexual, physical, and emotional violence significantly declined in 2019 compared with 2010, including unwanted sexual touching, for both females and males. Experience of pressured and forced sex among females also decreased between the surveys. Additionally, significantly more females sought and received services for sexual violence and significantly more males knew of a place to seek help in 2019 than in 2010. The prevalence of several risk factors for violence and HIV also declined, including infrequent condom use, endorsement of inequitable gender norms, endorsement of norms justifying wife beating, and never testing for HIV. INTERPRETATION: Kenya observed significant declines in the prevalence of lifetime violence and some risk factors for violence and HIV, and improvements in some service seeking indicators between 2010 and 2019. Continued prioritisation of preventing and responding to violence in Kenya could contribute to further reductions in violence and its negative outcomes. Other countries in the region that have made substantial investments and implemented similar violence prevention programmes could use repeat VACS data to monitor violence and related outcomes over time. FUNDING: None. |
COVID-19-Associated Orphanhood and Caregiver Death in the United States
Hillis SD , Blenkinsop A , Villaveces A , Annor FB , Liburd L , Massetti GM , Demissie Z , Mercy JA , Nelson CA3rd , Cluver L , Flaxman S , Sherr L , Donnelly CA , Ratmann O , Unwin HJT . Pediatrics 2021 148 (6) BACKGROUND: Most coronavirus disease 2019 (COVID-19) deaths occur among adults, not children, and attention has focused on mitigating COVID-19 burden among adults. However, a tragic consequence of adult deaths is that high numbers of children might lose their parents and caregivers to COVID-19-associated deaths. METHODS: We quantified COVID-19-associated caregiver loss and orphanhood in the United States and for each state using fertility and excess and COVID-19 mortality data.We assessed burden and rates of COVID-19-associated orphanhood and deaths of custodial and coresiding grandparents, overall and by race and ethnicity. We further examined variations in COVID-19-associated orphanhood by race and ethnicity for each state. RESULTS: We found that fromApril 1, 2020, through June 30, 2021,>140 000 children in the United States experienced the death of a parent or grandparent caregiver. The risk of such losswas 1.1 to 4.5 times higher among children of racial and ethnicminority groups compared with non-Hispanic White children. The highest burden of COVID-19-associated death of parents and caregivers occurred in Southern border states for Hispanic children, in Southeastern states for Black children, and in stateswith tribal areas for American Indian and/or Alaska Native populations. CONCLUSIONS: We found substantial disparities in distributions of COVID-19-associated death of parents and caregivers across racial and ethnic groups. Children losing caregivers to COVID-19 need care and safe, stable, and nurturing families with economic support, quality child care, and evidence-based parenting support programs. There is an urgent need tomount an evidence-based comprehensive response focused on those children at greatest risk in the statesmost affected. © 2021 American Academy of Pediatrics.

Malar J 2020 19 (1) 391 BACKGROUND: Histidine-rich protein 2 (HRP2)-based malaria rapid diagnostic tests (RDTs) are effective and widely used for the detection of wild-type Plasmodium falciparum infections. Although recent studies have reported false negative HRP2 RDT results due to pfhrp2 and pfhrp3 gene deletions in different countries, there is a paucity of data on the deletions of these genes in Tanzania. METHODS: A community-based cross-sectional survey was conducted between July and November 2017 in four regions: Geita, Kigoma, Mtwara and Ruvuma. All participants had microscopy and RDT performed in the field and provided a blood sample for laboratory multiplex antigen detection (for Plasmodium lactate dehydrogenase, aldolase, and P. falciparum HRP2). Samples showing RDT false negativity or aberrant relationship of HRP2 to pan-Plasmodium antigens were genotyped to detect the presence/absence of pfhrp2/3 genes. RESULTS: Of all samples screened by the multiplex antigen assay (n = 7543), 2417 (32.0%) were positive for any Plasmodium antigens while 5126 (68.0%) were negative for all antigens. The vast majority of the antigen positive samples contained HRP2 (2411, 99.8%), but 6 (0.2%) had only pLDH and/or aldolase without HRP2. Overall, 13 samples had an atypical relationship between a pan-Plasmodium antigen and HRP2, but were positive by PCR. An additional 16 samples with negative HRP2 RDT results but P. falciparum positive by microscopy were also chosen for pfhrp2/3 genotyping. The summation of false negative RDT results and laboratory antigen results provided 35 total samples with confirmed P. falciparum DNA for pfhrp2/3 genotyping. Of the 35 samples, 4 (11.4%) failed to consistently amplify positive control genes; pfmsp1 and pfmsp2 and were excluded from the analysis. The pfhrp2 and pfhrp3 genes were successfully amplified in the remaining 31 (88.6%) samples, confirming an absence of deletions in these genes. CONCLUSIONS: This study provides evidence that P. falciparum parasites in the study area have no deletions of both pfhrp2 and pfhrp3 genes. Although single gene deletions could have been missed by the multiplex antigen assay, the findings support the continued use of HRP2-based RDTs in Tanzania for routine malaria diagnosis. There is a need for the surveillance to monitor the status of pfhrp2 and/or pfhrp3 deletions in the future. |
Did internal displacement from the 2010 earthquake in Haiti lead to long-term violence against children A matched pairs study design
Cerna-Turoff I , Kane JC , Devries K , Mercy J , Massetti G , Baiocchi M . Child Abuse Negl 2020 102 104393 BACKGROUND: Empirical evidence is limited and contradictory on violence against children after internal displacement from natural disasters. Understanding how internal displacement affects violence is key in structuring effective prevention and response. OBJECTIVE: We examined the effect of internal displacement from the 2010 Haitian earthquake on long-term physical, emotional, and sexual violence against children and outlined a methodological framework to improve future evidence quality. PARTICIPANTS AND SETTING: We analyzed violence against adolescent girls and boys within the nationally representative, Haiti Violence Against Children Survey. METHODS: We pre-processed data by matching on pre-earthquake characteristics for displaced and non-displaced children and applied 95 % confidence intervals from McNemar's exact test, with sensitivity analyses, to evaluate differences in violence outcomes between matched pairs after the earthquake. RESULTS: Internal displacement was not associated with past 12-month physical, emotional, and sexual violence two years after the earthquake for girls and boys. Most violence outcomes were robust to potential unmeasured confounding. Odds ratios for any form of violence against girls were 0.84 (95 % CI: 0.52-1.33, p = 0.500) and against boys were 1.03 (95 % CI: 0.61-1.73, p = 1.000). CONCLUSIONS: Internal displacement was not a driver of long-term violence against children in Haiti. Current global protocols in disaster settings may initiate services after the optimal window of time to protect children from violence, and the post-displacement setting may be central in determining violence outcomes. The combination of specific data structures and matching methodologies is promising to increase evidence quality after rapid-onset natural disasters, especially in low-resource settings. |
Vital Signs: Estimated proportion of adult health problems attributable to adverse childhood experiences and implications for prevention - 25 states, 2015-2017
Merrick MT , Ford DC , Ports KA , Guinn AS , Chen J , Klevens J , Metzler M , Jones CM , Simon TR , Daniel VM , Ottley P , Mercy JA . MMWR Morb Mortal Wkly Rep 2019 68 (44) 999-1005 INTRODUCTION: Adverse childhood experiences, such as violence victimization, substance misuse in the household, or witnessing intimate partner violence, have been linked to leading causes of adult morbidity and mortality. Therefore, reducing adverse childhood experiences is critical to avoiding multiple negative health and socioeconomic outcomes in adulthood. METHODS: Behavioral Risk Factor Surveillance System data were collected from 25 states that included state-added adverse childhood experience items during 2015-2017. Outcomes were self-reported status for coronary heart disease, stroke, asthma, chronic obstructive pulmonary disease, cancer (excluding skin cancer), kidney disease, diabetes, depression, overweight or obesity, current smoking, heavy drinking, less than high school completion, unemployment, and lack of health insurance. Logistic regression modeling adjusting for age group, race/ethnicity, and sex was used to calculate population attributable fractions representing the potential reduction in outcomes associated with preventing adverse childhood experiences. RESULTS: Nearly one in six adults in the study population (15.6%) reported four or more types of adverse childhood experiences. Adverse childhood experiences were significantly associated with poorer health outcomes, health risk behaviors, and socioeconomic challenges. Potential percentage reductions in the number of observed cases as indicated by population attributable fractions ranged from 1.7% for overweight or obesity to 23.9% for heavy drinking, 27.0% for chronic obstructive pulmonary disease, and 44.1% for depression. CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Efforts that prevent adverse childhood experiences could also potentially prevent adult chronic conditions, depression, health risk behaviors, and negative socioeconomic outcomes. States can use comprehensive public health approaches derived from the best available evidence to prevent childhood adversity before it begins. By creating the conditions for healthy communities and focusing on primary prevention, it is possible to reduce risk for adverse childhood experiences while also mitigating consequences for those already affected by these experiences. |
Workplace interventions for intimate partner violence: A systematic review
Adhia A , Gelaye B , Friedman LE , Marlow LY , Mercy JA , Williams MA . J Workplace Behav Health 2019 34 (3) 149-166 Workplace interventions represent important opportunities to increase awareness of and adherence to disease prevention and health promotion initiatives. However, research on workplace interventions for intimate partner violence (IPV) has not been systematically evaluated. This systematic review summarizes existing studies evaluating workplace interventions for IPV. PubMed, PsycINFO, Business Source Complete, Web of Science, and Social Services Abstracts were systematically searched for English-language studies published before November 2017. Six studies evaluating five interventions were included. Only one study used a randomized design, and only two studies measured whether outcomes were sustained over time. None of the interventions addressed perpetrators of IPV. Interventions focused on recognizing signs of abuse, responding to victims, and providing referrals to community-based resources. Methodological rigor of included studies varied, but all reported at least one intervention-related benefit. Findings included improved awareness of IPV, increased provision of information to victims, and greater willingness to intervene if an employee may be experiencing IPV. Although sparse, available evidence suggests there are potential benefits of workplace interventions for IPV. It is important for future interventions to focus on primary and secondary prevention of IPV and address perpetration, and for investigators to use rigorous study designs and measure whether effects are sustained. |
Firearm homicides and suicides in major metropolitan areas - United States, 2012-2013 and 2015-2016
Kegler SR , Dahlberg LL , Mercy JA . MMWR Morb Mortal Wkly Rep 2018 67 (44) 1233-1237 Firearm homicides and suicides represent a continuing public health concern in the United States. During 2015-2016, a total of 27,394 firearm homicides (including 3,224 [12%] among persons aged 10-19 years) and 44,955 firearm suicides (including 2,118 [5%] among persons aged 10-19 years) occurred among U.S. residents (1). This report updates an earlier report (2) that provided statistics on firearm homicides and suicides in major metropolitan areas during 2006-2007 and 2009-2010, and places continued emphasis on youths, in recognition of the importance of early prevention efforts. Firearm homicide and suicide rates were determined for the 50 most populous U.S. metropolitan statistical areas (MSAs)* during 2012-2013 and 2015-2016 using mortality data from the National Vital Statistics System (NVSS) and population data from the U.S. Census Bureau. In contrast to the earlier report, which indicated that firearm homicide rates among persons of all ages had been declining both nationally and in large MSAs overall, current findings show that rates have returned to levels comparable to those observed during 2006-2007. Consistent with the earlier report, these findings show that firearm suicide rates among persons aged >/=10 years have continued to increase, both nationally and in large MSAs overall. Although firearm suicide rates among youths remain notably lower than those among persons of all ages, youth rates have also increased both nationally and in large MSAs collectively. These findings can inform ongoing development and monitoring of strategies directed at reducing firearm-related violence. |
Violence-related disparities experienced by black youth and young adults: Opportunities for prevention
Sheats K , Irving SM , Mercy J , Simon TR , Crosby A , Ford DC , Merrick M , Annor F , Morgan RE . Am J Prev Med 2018 55 (4) 462-469 INTRODUCTION: The purpose of this study is to characterize violence-related disparities experienced by young blacks in the U.S. Reducing violence experienced by blacks, particularly youth, who are at substantially higher risk, is essential to improving the health of blacks in the U.S. METHODS: Data from four independent data sets for youth and adults were analyzed to examine rates of homicide, assault, injury from a physical fight, bullying victimization, and missing school because of safety concerns for non-Hispanic blacks and whites aged 10-34 years between 2010 and 2015. Disparities in adverse childhood experiences (e.g., exposure to violence and household challenges) and physical/mental health outcomes in adulthood were examined. Data were analyzed in 2017. RESULTS: Black adolescents and young adults are at higher risk for the most physically harmful forms of violence (e.g., homicides, fights with injuries, aggravated assaults) compared with whites. In addition, black adults reported exposure to a higher number of adverse childhood experiences than whites. These adverse childhood experiences were positively associated with increased odds of self-reported coronary heart disease, fair or poor physical health, experiencing frequent mental distress, heavy drinking, and current smoking. CONCLUSIONS: Disproportionate exposure to violence for blacks may contribute to disparities in physical injury and long-term mental and physical health. Understanding the violence experiences of this age group and the social contexts surrounding these experiences can help improve health for blacks in the U.S. Communities can benefit from the existing evidence about policies and programs that effectively reduce violence and its health and social consequences. |
Adverse childhood experiences and HIV sexual risk-taking behaviors among young adults in Malawi
VanderEnde K , Chiang L , Mercy J , Shawa M , Hamela J , Maksud N , Gupta S , Wadonda-Kabondo N , Saul J , Gleckel J , Kress H , Hillis S . J Interpers Violence 2018 33 (11) 1710-1730 Adverse childhood experiences (ACEs) exhibit a dose-response association with poor health outcomes in adulthood, including HIV. In this analysis, we explored the relationship between ACEs and HIV sexual risk-taking behaviors among young adults in Malawi. We analyzed responses from sexually active 19- to 24-year-old males and females ( n = 610) participating in the Malawi Violence Against Children Survey. We tested the association between respondents' exposure to six ACEs (having experienced emotional, physical, or sexual violence; witnessing intimate partner violence or an attack in the community; one or both parents died) and infrequent condom use in the past year and multiple sexual partners in the past year. We used logistic regression to test the association between ACEs and these sexual risk-taking behaviors. A majority (82%) of respondents reported at least 1 ACE, and 29% reported 3+ ACEs. We found positive unadjusted associations between the number of ACEs (1-2 and 3+ vs. none) and both outcomes. In adjusted models, we found positive associations between the number of ACEs and infrequent condom use (adjusted odds ratio [aOR]: 2.7, 95% confidence interval [CI]: [1.0, 7.8]; aOR: 3.7, CI: [1.3, 11.1]). Among young adults in Malawi, exposure to ACEs is positively associated, in a dose-response fashion, with engaging in some sexual risk-taking behaviors. HIV prevention efforts in Malawi may benefit from prioritizing programs and policies aimed at preventing and responding to violence against children. |
The economic burden of child sexual abuse in the United States
Letourneau EJ , Brown DS , Fang X , Hassan A , Mercy JA . Child Abuse Negl 2018 79 413-422 The present study provides an estimate of the U.S. economic impact of child sexual abuse (CSA). Costs of CSA were measured from the societal perspective and include health care costs, productivity losses, child welfare costs, violence/crime costs, special education costs, and suicide death costs. We separately estimated quality-adjusted life year (QALY) losses. For each category, we used the best available secondary data to develop cost per case estimates. All costs were estimated in U.S. dollars and adjusted to the reference year 2015. Estimating 20 new cases of fatal and 40,387 new substantiated cases of nonfatal CSA that occurred in 2015, the lifetime economic burden of CSA is approximately $9.3 billion, the lifetime cost for victims of fatal CSA per female and male victim is on average $1,128,334 and $1,482,933, respectively, and the average lifetime cost for victims of nonfatal CSA is of $282,734 per female victim. For male victims of nonfatal CSA, there was insufficient information on productivity losses, contributing to a lower average estimated lifetime cost of $74,691 per male victim. If we included QALYs, these costs would increase by approximately $40,000 per victim. With the exception of male productivity losses, all estimates were based on robust, replicable incidence-based costing methods. The availability of accurate, up-to-date estimates should contribute to policy analysis, facilitate comparisons with other public health problems, and support future economic evaluations of CSA-specific policy and practice. In particular, we hope the availability of credible and contemporary estimates will support increased attention to primary prevention of CSA. |
Applying structural equation modeling to measure violence exposure and its impact on mental health: Malawi Violence Against Children and Young Women Survey, 2013
Fan AZ , Liu J , Kress H , Gupta S , Shawa M , Wadonda-Kabondo N , Mercy J . J Interpers Violence 2017 36 886260517741214 This study examines exposure to multiple forms of violence among Malawian children and youth and their association with mental health outcomes. The Malawi Violence Against Children and Young Women Survey was conducted among a nationally representative sample of males and females aged 13 to 24 years ( n = 2,162) in Malawi in 2013. The experience of sexual, physical, and emotional violence prior to age 18 and during the past 12 months and associated health outcomes were ascertained using a comprehensive interview. Latent factors of sexual violence, physical violence, and emotional violence as well as psychological distress were constructed. We examined whether the experience of violence was related to psychological distress after controlling for age and gender. Violence exposure prior to age 18 (early life) and during the past 12 months (proximal) were valid indicators for a latent factor representing overall lifetime violence exposure. Females were more likely to experience sexual violence, whereas males were more likely to experience physical violence. Experience of any type of violence decreased with age whereas experience of psychological distress increased with age. Current psychological distress was directly associated with exposure to sexual and emotional violence recently or during childhood. Exposure to multiple forms of violence during lifetime was related to two to seven folds higher odds of experiencing psychological distress compared with those who had never experienced violence. Future intervention strategies should address three forms of violence against children simultaneously in light of the associated adverse mental health outcomes. |
The experience of violence against children in domestic servitude in Haiti: Results from the Violence Against Children Survey, Haiti 2012
Gilbert L , Reza A , Mercy J , Lea V , Lee J , Xu L , Marcelin LH , Hast M , Vertefeuille J , Domercant JW . Child Abuse Negl 2017 76 184-193 BACKGROUND: There have been estimates that over 150,000 Haitian children are living in servitude. Child domestic servants who perform unpaid labor are referred to as "restaveks." Restaveks are often stigmatized, prohibited from attending school, and isolated from family placing them at higher risk for experiencing violence. In the absence of national data on the experiences of restaveks in Haiti, the study objective was to describe the sociodemographic characteristics of restaveks in Haiti and to assess their experiences of violence in childhood. METHODS: The Violence Against Children Survey was a nationally representative, cross-sectional household survey of 13-24year olds (n=2916) conducted May-June 2012 in Haiti. A stratified three-stage cluster design was used to sample households and camps containing persons displaced by the 2010 earthquake. Respondents were interviewed to assess lifetime prevalence of physical, emotional, and sexual violence occurring before age 18. Chi-squared tests were used to assess the association between having been a restavek and experiencing violence in childhood. FINDINGS: In this study 17.4% of females and 12.2% of males reported having been restaveks before age 18. Restaveks were more likely to have worked in childhood, have never attended school, and to have come from a household that did not have enough money for food in childhood. Females who had been restaveks in childhood had higher odds of reporting childhood physical (OR 2.04 [1.40-2.97]); emotional (OR 2.41 [1.80-3.23]); and sexual violence (OR 1.86 [95% CI 1.34-2.58]) compared to females who had never been restaveks. Similarly, males who had ever been restaveks in childhood had significantly increased odds of emotional violence (OR 3.06 [1.99-4.70]) and sexual violence (OR 1.85 [1.12-3.07]) compared to males who had never been restaveks, but there was no difference in childhood physical violence. INTERPRETATION: This study demonstrates that child domestic servants in Haiti experience higher rates of childhood violence and have less access to education and financial resources than other Haitian children. These findings highlight the importance of addressing both the lack of human rights law enforcement and the poor economic circumstances that allow the practice of restavek to continue in Haiti. |
Severe parechovirus 3 infections in young infants - Kansas and Missouri, 2014
Midgley CM , Jackson MA , Selvarangan R , Franklin P , Holzschuh EL , Lloyd J , Scaletta J , Straily A , Tubach S , Willingham A , Nix WA , Oberste MS , Harrison CJ , Hunt C , Turabelidze G , Gerber SI , Watson JT . J Pediatric Infect Dis Soc 2017 7 (2) 104-112 Background: Infection with parechovirus type 3 (PeV3) can cause severe neurologic and sepsis-like illness in young infants; clinical and epidemiologic descriptions have been limited. We aimed to characterize PeV3 illness and explore risk factors for acquisition in a cluster of neonatal cases at Children's Mercy Hospital in Kansas City, Missouri. Methods: Cerebrospinal fluid specimens were obtained from infants aged <180 days who were hospitalized with sepsis-like illness or meningitis between June 1 and November 1, 2014. PeV-positive specimens were sequenced at the Centers for Disease Control and Prevention. We reviewed the medical and birth charts of the infants and performed face-to-face parent interviews. We analyzed characteristics according to infant age and intensive care admission status. Results: We identified 35 cases of PeV infection in infants aged 5 to 56 days. Seven infants required intensive care (median age, 11 days vs 27 days among those who did not require intensive care; P = .0044). Six of these 7 infants had neurologic manifestations consistent with seizures, and all 6 of them were treated with acyclovir but subsequently tested negative for herpes simplex virus. Virus sequences formed 2 lineages, both of which were associated with severe illness. Half of the infants were reported to have household contacts who were ill during the week before onset. Infants aged ≤7 days at onset were more likely to have been delivered at the same hospital. Conclusions: PeV3 can cause severe neurologic illness in neonates, and younger infants are more likely to require intensive care. PeV3 should be considered along with herpes simplex virus and other pathogens when evaluating young infants with sepsis-like illness or meningitis. More widespread testing for PeV3 would enable us to gain a better understanding of the clinical scope and circulation of this virus. |
Violent experiences in childhood are associated with men's perpetration of intimate partner violence as a young adult: a multistage cluster survey in Malawi
VanderEnde K , Mercy J , Shawa M , Kalanda M , Hamela J , Maksud N , Ross B , Gupta S , Wadonda-Kabondo N , Hillis S . Ann Epidemiol 2016 26 (10) 723-728 PURPOSE: To examine the association between exposures to violence in childhood, including exposure to multiple forms of violence, with young men's perpetration of intimate partner violence (IPV) in Malawi. METHODS: We analyzed data from 450 ever-partnered 18- to 24-year-old men interviewed in the Malawi Violence Against Children and Young Woman Survey, a nationally representative, multistage cluster survey conducted in 2013. We estimated the weighted prevalence for perpetration of physical and/or sexual IPV and retrospective reporting of experiences of violence in childhood and examined the associations between childhood experiences of violence and perpetration of IPV using logistic regression. RESULTS: Among young men in Malawi, lifetime prevalence for perpetration of sexual IPV (24%) was higher than for perpetration of physical IPV (9%). In logistic regression analyses, the adjusted odds ratios for perpetration of sexual IPV increased in a statistically significant gradient fashion, from 1.2 to 1.4 to 3.7 to 4.3 for young men with exposures to one, two, three, and four or more forms of violence in childhood, respectively. CONCLUSIONS: Among young men in Malawi, exposure to violence in childhood is associated with an increased odds of perpetrating IPV, highlighting the need for programs and policies aimed at interrupting the intergenerational transmission of violence. |
