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.

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.

Adverse childhood experiences are potentially traumatic events that occur in childhood that have been associated with lifelong chronic health problems, mental illness, substance misuse, and decreased life opportunities. Therefore, preventing adverse childhood experiences is critical to improving health and socioeconomic outcomes throughout the lifespan. The Preventing Adverse Childhood Experiences: Data to Action (CDC-RFA-CE20-2006) funding initiative is a comprehensive public health approach to adverse childhood experience prevention that aims to understand the prevalence of and risk factors for adverse childhood experiences among youth, track changes in adverse childhood experience prevalence over time, focus prevention strategies, and ultimately measure the success of those evidence-based prevention strategies. Recipients will achieve the goals of the initiative by leveraging multisector partnerships and resources to: (1) enhance and build infrastructure for state-level data collection, analysis, and application of adverse childhood experiences related surveillance data; (2) implement at least 2 prevention strategies based on the best available evidence to prevent adverse childhood experiences; and (3) undertake data to action activities to leverage statewide surveillance data to inform and tailor adverse childhood experience prevention activities. Since the start of this initiative, recipients have focused on building surveillance capacity based on the needs of their individual states; implementing strategies and approaches based on the best available evidence to better prevent adverse childhood experiences; and ultimately improve the mental, physical, and social well-being of their populations. Although evaluation of Preventing Adverse Childhood Experiences: Data to Action is ongoing, this article outlines the current recipient surveillance, prevention, and data-to-action implementation efforts.

Through the Essentials for Childhood program, the Centers for Disease Control and Prevention funds 7 state health departments (states) to address the urgent public health problem of adverse childhood experiences and child abuse and neglect, in particular. Through interviews and document reviews, the paper highlights the early implementation of 2 primary prevention strategies from the Centers for Disease Control and Prevention's child abuse and neglect technical package with the greatest potential for broad public health impact to prevent adverse childhood experiences-strengthening economic supports and changing social norms. States are focused on advancing family-friendly work policies such as paid family and medical leave, livable wage policies, flexible and consistent work schedules, as well as programs and policies that strengthen household financial security such as increasing access to Earned Income Tax Credit. In addition, states are launching campaigns that focus on reframing the way people think about child abuse and neglect and who is responsible for preventing it. State-level activities such as establishing a diverse coalition of partners, program champions, and state action planning have helped to leverage and align resources needed to implement, evaluate, and sustain programs. States are working to increase awareness and commitment to multisector efforts that reduce adverse childhood experiences and promote safe, stable, nurturing relationships and environments for children. Early learning from this funding opportunity indicates that using a public health approach, states are well positioned to implement comprehensive, primary prevention strategies and approaches to ensure population-level impact for preventing child abuse and neglect and other adverse childhood experience.

BACKGROUND: Although childhood obesity rates have been high in the last few decades, recent national reports indicate a stabilization of rates among some subpopulations of children. This study examines the implementation of initiatives, policies, and programs (referred to as strategies) in four communities that experienced declines in childhood obesity between 2003 and 2012. METHODS AND RESULTS: The Childhood Obesity Decline project verified obesity declines and identified strategies that may have influenced and supported the decline in obesity. The project used an adaptation of the Systematic Screening and Assessment method to identify key informants in each site. Four settings were highlighted related to childhood: (1) communities, (2) schools, (3) early care and education, and (4) healthcare. The findings indicate that programs and policies were implemented across local settings (primarily in schools and early childhood settings) and at the state level, during a timeframe of supportive federal policies and initiatives. CONCLUSIONS: Multilevel approaches were aimed to improve the nutrition and physical activity environments where children spend most of their time. We hypothesized that other, more distal strategies amplified and reinforced the impact of the efforts that more directly targeted children. The simultaneous public health messaging and multilayered initiatives, supported by cross-sector partnerships and active, high-level champions, were identified as likely important contributors to success in attaining declines in rates of childhood obesity.

This introduction is an overview of the articles presented in this supplement that describe implementation and evaluation activities conducted as part of the Centers for Disease Control and Prevention's (CDC's) Communities Putting Prevention to Work (CPPW) initiative. CPPW was one of the largest federal investments ever to combat chronic diseases in the United States. CPPW supported high-impact, jurisdiction-wide policy, systems, and environmental changes to improve health by increasing access to physical activity and healthy foods, and by decreasing tobacco use and exposure to secondhand smoke. The articles included in this supplement describe implementation and evaluation efforts of strategies implemented as part of CPPW by local awardees. This supplement is intended to guide the evidence base for public health interventions on the basis of jurisdiction-wide policy and environmental-level improvements and to encourage rigorous evaluation of the public health interventions.
