Clin Infect Dis 2021 73 S42-S44 Large public-health training events may result in SARS-CoV-2 transmission. Universal SARS-CoV-2 testing during trainings for the Uganda Population-based HIV Impact Assessment identified 28/475 (5.9%) individuals with COVID-19 among attendees; most (89.3%) were asymptomatic. Effective COVID-19 mitigation measures, along with SARS-CoV-2 testing, are recommended for in-person trainings, particularly when trainees will have subsequent contact with survey participants. |
Estimating the prevalence and predictors of incorrect condom use among sexually active adults in Kenya: results from a nationally representative survey
Grasso MA , Schwarcz S , Galbraith JS , Musyoki H , Kambona C , Kellogg TA . Sex Transm Dis 2016 43 (2) 87-93 BACKGROUND: Condom use continues to be an important primary prevention tool to reduce the acquisition and transmission of HIV and other sexually transmitted infections. However, incorrect use of condoms can reduce their effectiveness. METHODS: Using data from a 2012 nationally representative cross-sectional household survey conducted in Kenya, we analyzed a subpopulation of sexually active adults and estimated the percent that used condoms incorrectly during sex, and the type of condom errors. We used multivariable logistic regression to determine variables to be independently associated with incorrect condom use. RESULTS: Among 13,720 adolescents and adults, 8014 were sexually active in the previous 3 months (60.3%; 95% confidence interval [CI], 59.0-61.7). Among those who used a condom with a sex partner, 20% (95% CI, 17.4-22.6) experienced at least one instance of incorrect condom use in the previous 3 months. Of incorrect condom users, condom breakage or leakage was the most common error (52%; 95% CI, 44.5-59.6). Factors found to be associated with incorrect condom use were multiple sexual partnerships in the past 12 months (2 partners: adjusted odds ratio [aOR], 1.5; 95% CI, 1.0-2.0; P = 0.03; ≥3: aOR, 2.3; 95% CI, 1.5-3.5; P < 0.01) and reporting symptoms of a sexually transmitted infection (aOR, 2.8; 95% CI, 1.8-4.3; P < 0.01). CONCLUSIONS: Incorrect condom use is frequent among sexually active Kenyans and this may translate into substantial HIV transmission. Further understanding of the dynamics of condom use and misuse, in the broader context of other prevention strategies, will aid program planners in the delivery of appropriate interventions aimed at limiting such errors. |
Status of voluntary medical male circumcision in Kenya: findings from 2 nationally representative surveys in Kenya, 2007 and 2012
Galbraith JS , Ochieng A , Mwalili S , Emusu D , Mwandi Z , Kim AA , Rutherford G , Maina WK , Kimanga DO , Chesang K , Cherutich P . J Acquir Immune Defic Syndr 2014 66 Suppl 1 S37-45 BACKGROUND: The Kenyan Ministry of Health initiated a voluntary medical male circumcision (VMMC) program in 2008. We used data from 2 nationally representative surveys to estimate trends in the number, demographic characteristics, and sexual behaviors of recently circumcised and uncircumcised HIV-uninfected men in Kenya. METHODS: We compared the proportion of circumcised men between the first and second Kenya AIDS Indicator Survey (KAIS 2007 and KAIS 2012) to assess the progress of Kenya's VMMC program. We calculated the number of uncircumcised HIV-uninfected men. We conducted descriptive analyses and used multivariable methods to identify the variables independently associated with HIV-uninfected uncircumcised men aged 15-64 years in the VMMC priority region of Nyanza. RESULTS: The proportion of men who reported being circumcised increased significantly from 85.0% in 2007 to 91.2% in 2012. The proportions of circumcised men increased in all regions, with the highest increases of 18.1 and 9.0 percentage points in the VMMC priority regions of Nyanza and Nairobi, respectively. Half (52.5%) of HIV-uninfected and uncircumcised men had never been married, and 84.6% were not using condoms at all times with their last sexual partner. CONCLUSIONS: VMMC prevalence has increased across Kenya demonstrating the success of the national program. Despite this accomplishment, the Nyanza region remains below the target to circumcise 80% of all eligible men aged 15-49 years between 2009 and 2013. As new cohorts of young men enter into adolescence, consistent focus is needed. To ensure sustainability of the VMMC program, financial resources and coordinated planning must continue. |
Orphans and vulnerable children in Kenya: results from a nationally representative population-based survey
Lee VC , Muriithi P , Gilbert-Nandra U , Kim AA , Schmitz ME , Odek J , Mokaya R , Galbraith JS . J Acquir Immune Defic Syndr 2014 66 Suppl 1 S89-97 BACKGROUND: In Kenya, it is estimated that there are approximately 3.6 million children aged <18 years who have been orphaned or who are vulnerable. We examined the data from the second Kenya AIDS Indicator Survey (KAIS 2012) to determine the number and profile of orphans and vulnerable children (OVC) in Kenya who were aged <18 years. METHODS: KAIS 2012 was a nationally representative, population-based household survey. We analyzed the data for all the children from birth to age 17 years who resided in an eligible household so as to determine whether their parents were alive or had been very ill to define their OVC status. RESULTS: We estimated that there were 2.6 million OVC in Kenya in 2012, of whom 1.8 million were orphans and 750,000 were vulnerable. Among orphans, 15% were double orphans. Over one-third of all the OVC were aged between 10 and 14 years. Households with ≥1 OVC (12% of all households) were usually in the lowest 2 wealth quintiles, and 22% of OVC households had experienced moderate or severe hunger. Receipt of OVC support services was low for medical (3.7%), psychological (4.1%), social (1.3%), and material support (6.2%); educational support was slightly more common (11.5%). Orphanhood among children aged <15 years increased from 1993 to 2003 (P < 0.01) but declined from 2003 to 2012 (P < 0.01). CONCLUSIONS: The 2.6 million OVC constitute a significant proportion of Kenya's population aged <18 years. Special attention should be paid to OVC to prevent further vulnerability and ensure their well-being and development as they transition into adulthood. |
Differences between HIV-positive and HIV-negative African American men who have sex with men in two major U.S. metropolitan areas
Robinson BB , Galbraith JS , Swinburne Romine RE , Zhang Q , Herbst JH . Arch Sex Behav 2013 42 (2) 267-78 Alarmingly high HIV prevalence rates among African American men who have sex with men (AAMSM) require the development of effective prevention interventions. In this study of AAMSM conducted in two cities, we explored similarities and differences between HIV-positive and HIV-negative AAMSM on sociodemographic variables, HIV-related risk behaviors, and attitudinal constructs. Differences emerged in several major life areas: (1) poverty, employment, and use of mental health services, (2) sexual risk behaviors, and (3) self-identification with gay identity and culture. With regard to sociodemographic indicators, HIV-positive AAMSM were doing worse than HIV-negative AAMSM in that they were more likely to be disabled, to be living below the poverty level, and accessing mental health services. With regard to risk behaviors and partner characteristics, HIV-positive AAMSM were acting more responsibly than their HIV-negative counterparts, as they were more likely to have used a condom the last time they had sex. In addition, when compared to their HIV-negative counterparts, HIV-positive AAMSM were more likely to have either no casual partners at all or main or casual partners who were HIV-positive, thus preventing new HIV transmission by partnering with other HIV-positive men. Attitudinally, HIV-positive men were more accepting of their sexual attractions to men and were more likely to identify as gay than their HIV-negative peers. Although causality cannot be determined, the findings of this study can be used to strengthen HIV prevention efforts by improving the selection of targeted behaviors and prevention messages for HIV-positive and HIV-negative AAMSM. |
The effectiveness of group-based comprehensive risk-reduction and abstinence education interventions to prevent or reduce the risk of adolescent pregnancy, human immunodeficiency virus, and sexually transmitted infections: two systematic reviews for the Guide to Community Preventive Services
Chin HB , Sipe TA , Elder R , Mercer SL , Chattopadhyay SK , Jacob V , Wethington HR , Kirby D , Elliston DB , Griffith M , Chuke SO , Briss SC , Ericksen I , Galbraith JS , Herbst JH , Johnson RL , Kraft JM , Noar SM , Romero LM , Santelli J , Community Preventive Services Task Force . Am J Prev Med 2012 42 (3) 272-94 CONTEXT: Adolescent pregnancy, HIV, and other sexually transmitted infections (STIs) are major public health problems in the U.S. Implementing group-based interventions that address the sexual behavior of adolescents may reduce the incidence of pregnancy, HIV, and other STIs in this group. EVIDENCE ACQUISITION: Methods for conducting systematic reviews from the Guide to Community Preventive Services were used to synthesize scientific evidence on the effectiveness of two strategies for group-based behavioral interventions for adolescents: (1) comprehensive risk reduction and (2) abstinence education on preventing pregnancy, HIV, and other STIs. Effectiveness of these interventions was determined by reductions in sexual risk behaviors, pregnancy, HIV, and other STIs and increases in protective sexual behaviors. The literature search identified 6579 citations for comprehensive risk reduction and abstinence education. Of these, 66 studies of comprehensive risk reduction and 23 studies of abstinence education assessed the effects of group-based interventions that address the sexual behavior of adolescents, and were included in the respective reviews. EVIDENCE SYNTHESIS: Meta-analyses were conducted for each strategy on the seven key outcomes identified by the coordination team-current sexual activity; frequency of sexual activity; number of sex partners; frequency of unprotected sexual activity; use of protection (condoms and/or hormonal contraception); pregnancy; and STIs. The results of these meta-analyses for comprehensive risk reduction showed favorable effects for all of the outcomes reviewed. For abstinence education, the meta-analysis showed a small number of studies, with inconsistent findings across studies that varied by study design and follow-up time, leading to considerable uncertainty around effect estimates. CONCLUSIONS: Based on these findings, group-based comprehensive risk reduction was found to be an effective strategy to reduce adolescent pregnancy, HIV, and STIs. No conclusions could be drawn on the effectiveness of group-based abstinence education. |
HIV prevention among African American youth: how well have evidence-based interventions addressed key theoretical constructs?
Romero LM , Galbraith JS , Wilson-Williams L , Gloppen KM . AIDS Behav 2011 15 (5) 976-91 Certain constructs are demonstrated in the research literature to be related to HIV risk behaviors among African American adolescents. This study examines how well these constructs are addressed in evidence-based interventions (EBIs) developed for this population. A literature review on variables for sexual risk behaviors among African American adolescents was undertaken. Simultaneously, a review was conducted of the contents of HIV-prevention EBIs. To facilitate comparison, findings from both were organized into constructs from prominent behavior change theories. Analysis showed that environmental conditions and perceived norms were frequently associated with sexual risk behaviors in the literature, while EBIs devoted considerable time to knowledge, skills, and self-efficacy. Findings imply that (a) EBIs might be complemented with activities that focus on important constructs identified in the literature and (b) researchers should better assess the relationship between skill development and HIV risk behaviors. Implications for practice and research are discussed. |
Taxonomy for strengthening the identification of core elements for evidence-based behavioral interventions for HIV/AIDS prevention
Galbraith JS , Herbst JH , Whittier DK , Jones PL , Smith BD , Uhl G , Fisher HH . Health Educ Res 2011 26 (5) 872-85 The concept of core elements was developed to denote characteristics of an intervention, such as activities or delivery methods, presumed to be responsible for the efficacy of evidence-based behavioral interventions (EBIs) for HIV/AIDS prevention. This paper describes the development of a taxonomy of core elements based on a literature review of theoretical approaches and characteristics of EBIs. Sixty-one categories of core elements were identified from the literature and grouped into three distinct domains: implementation, content and pedagogy. The taxonomy was tested by categorizing core elements from 20 HIV prevention EBIs disseminated by Centers for Disease Control and Prevention. Results indicated that core elements represented all three domains but several were difficult to operationalize due to vague language or the inclusion of numerous activities or constructs. A process is proposed to describe core elements in a method that overcomes some of these challenges. The taxonomy of core elements can be used to identify core elements of EBIs, strengthen the translation of EBIs from research to practice and guide future research seeking to identify essential core elements in prevention interventions. |
Exploring implementation and fidelity of evidence-based behavioral interventions for HIV prevention: lessons learned from the focus on kids diffusion case study
Galbraith JS , Stanton B , Boekeloo B , King W , Desmond S , Howard D , Black MM , Carey JW . Health Educ Behav 2009 36 (3) 532-49 Evidence-based interventions (EBIs) are used in public health to prevent HIV infection among youth and other groups. EBIs include core elements, features that are thought to be responsible for the efficacy of interventions. The authors evaluate experiences of organizations that adopted an HIV-prevention EBI, Focus on Kids (FOK), and their fidelity to the intervention's eight core elements. A cross-sectional telephone survey was administered to 34 staff members from organizations that had previously implemented FOK. Questions assessed how the organization adhered to, adapted, dropped, or altered the intervention. None of the organizations implemented all eight core elements. This study underscores the importance for HIV intervention researchers to clearly identify and describe core elements. More effort is needed to reflect the constraints practitioners face in nonresearch settings. To ensure intervention effectiveness, additional research and technical assistance are needed to help organizations implement HIV prevention EBIs with fidelity. |
