Association between Childhood Maltreatment and Depressive and Anxiety Symptoms among Men Who Have Sex with Men in Los Angeles
Adverse childhood experiences (ACEs) have been associated with poor mental health outcomes in adulthood. Childhood maltreatment is related to both depressive and anxiety symptoms. Our objective was to investigate these associations among low-income, mostly Black and Latino men who have sex with men (MSM), as these may be a particularly vulnerable population group. Data come from a longitudinal study of MSM with varied substance use behaviors (n =…
Real World Feedback
To effectively respond to the COVID-19 pandemic, California had to quickly mobilize a substantial number of case investigators (CIs) and contact tracers (CTs). This workforce was comprised primarily of redirected civil servants with diverse educational and professional backgrounds. The purpose of this evaluation was to understand whether the weeklong, remote course developed to train California's CI/CT workforce (i.e., Virtual Training Academy) a…

The purpose of this study was to evaluate if watching the CLV Season 2 series online had an impact on people's health knowledge, attitudes, and norms, focusing on populations in francophone West Africa. Methods: Between July 2019 and October 2019, viewers of CLV and non-viewers were rec…
Perceived social support moderates the association between household dysfunction adverse childhood experiences (ACEs) and self-reported drug use among men who have sex with men in Los Angeles, Califor…
Perceived social support emerged as a potential buffering factor for any reported drug use, particularly for the single ACE of household substance use history. Given that the association between ACEs and drug use was weak among those with higher levels of perceived social support, promotion of social ties in the community may help reduce the burden of substance use among MSM exposed to ACEs

Widespread community transmission necessitates a large, diverse workforce with specialized knowledge and skills. The University of California, San Francisco and Los Angeles partnered with the California Department of Public Health to rapidly mobilize and train a CI/CT workforce. In April through August 2020, a team of public health practitioners and heal…
Food insecurity partially mediates the association between drug use and depressive symptoms among men who have sex with men in Los Angeles, California
Objective: To understand the relationship between drug use, food insecurity (FI) and mental health among men who have sex with men (MSM). Design: Cohort study (2014–2019) with at least one follow-up. Setting: Visits at 6-month intervals included self-assessment for FI and depressive symptoms. Urine testing results confirmed drug use. Factors associated with FI were assessed using multiple logistic regression with random effects for repeated measu…
Staff-perceived barriers to nutrition intervention in substance use disorder treatment
Objective: While organisational change in substance use disorder (SUD) treatment has been extensively studied, there is no research describing facility-wide changes related to nutrition interventions. This study evaluates staff-perceived barriers to change before and after a wellness initiative. Design: A pre-intervention questionnaire was administered to participating staff prior to facility-wide changes ( n 40). The questions were designed to a…
Establishment and Evaluation of a Large Contact-Tracing and Case Investigation Virtual Training Academy
During the COVID-19 pandemic, the Virtual Training Academy (VTA) was established to rapidly develop a contact-tracing workforce for California. Through June 2021, more than 10 000 trainees enrolled in a contact-tracing or case investigation course at the VTA. To evaluate program effectiveness, we analyzed trainee pre- and postassessment results using the Wilcoxon signed-rank test. There was a statistically significant (P
Cardiovascular disease behavioral risk factors among Latinos by citizenship and documentation status
This study observes that the healthy Latino immigrant advantage seems to apply to undocumented female immigrants, but it does not necessarily extend to undocumented male immigrants who had similar behavioral risk profiles to US-born Latinos
Strategies for Effective Collaboration with Middle School Physical Education Teachers
Efforts to improve PE programs can benefit from a school-engaged research approach that directly involves teachers, fosters mutually beneficial relationships, and integrates the schools' perspective in the research process
Widening socio-economic disparities in early childhood obesity in Los Angeles County after the Great Recession
Objective While economic crises can increase socio-economic disparities in health, little is known about the impact of the 2008–09 Great Recession on obesity prevalence among children, especially low-income children. The present study examined whether socio-economic disparities in obesity among children of pre-school age participating in a federal nutrition assistance programme have changed since the recession. Design A pre–post observational stu…
A Program for Local Health Departments to Adapt and Implement Evidence-Based Emergency Preparedness Programs
The goal of this project was to enhance the capacity of local health departments to translate and implement evidence-based programs in emergency preparedness by using the Getting To Outcomes approach. Our evaluation determined that local health department staff reported improved capacities. A “Getting To Outcomes Guide for Community Emergency Preparedness” guidebook was produced and is available online
A corner store intervention to improve access to fruits and vegetables in two Latino communities
Objective Investments have been made to alter the food environment of neighbourhoods that have a disproportionate number of unhealthy food venues. Corner store conversions are one strategy to increase access to fruits and vegetables (F&V). Although the literature shows modest success, the effectiveness of these interventions remains equivocal. The present paper reports on the evaluation of Proyecto MercadoFRESCO, a corner store conversion interve…
A Smartphone Application to Reduce Time-to-Notification of Sexually Transmitted Infections
Objectives. To measure whether the implementation of Healthvana—an online patient engagement platform and smartphone application—reduced the number of days between sexually transmitted infection (STI) testing, notification, and treatment at AIDS Healthcare Foundation (AHF) Wellness Centers. Methods. We analyzed the retrospective data for 917 male clients who tested positive and received treatment for chlamydia, gonorrhea, or syphilis between Janu…
Ethnicity and Income Impact on Bmi and Stature of School Children Living in Urban Southern Mexico
Obesity affects quality of life and increases the risk of morbidity and mortality. Mexico, a middle-income country, has a high prevalence of overweight and obesity among urban children. Merida is the most populated and growing city in southern Mexico with a mixed Mayan and non-Maya population. Local urbanization and access to industrialized foods have impacted the eating habits and physical activity of children, increasing the risk of overweight …
Substantial improvements not seen in health behaviors following corner store conversions in two Latino food swamps
Results suggest limited effectiveness of food retail interventions on improving health behaviors. Future research should focus on other strategies to reduce community-level obesity
Consistency of Moderate to Vigorous Physical Activity in Middle School Physical Education
This study assessed the consistency of moderate to vigorous physical activity (MVPA) in a sample of middle school physical education lessons. Random intercept hierarchical linear regressions were employed to model the relationship between consistency of MVPA and independent variables, including lesson and teacher characteristics. Larger classes spent significantly more time in consistent MVPA in the absence of controlling for teacher characterist…
Comparing Lay Community and Academic Survey Center Interviewers in Conducting Household Interviews in Latino Communities
With a lower cost per completed survey and lower item nonresponse rates, lay community interviewers are a viable alternative to professional interviewers for fieldwork in community-based research. Additional research is needed to assess other important aspects of data quality interviewer such as interviewer effects and response error
Trends in racial/ethnic disparities in overweight self-perception among US adults, 1988–1994 and 1999–2008
Objective Weight self-perceptions, or how a person perceives his/her weight status, may affect weight outcomes. We use nationally representative data from 1988–1994 and 1999–2008 to examine racial/ethnic disparities in weight self-perceptions and understand how disparities have changed over time. Design Using data from two time periods, 1988–1994 and 1999–2008, we calculated descriptive statistics, multivariate logistic regression models and pred…
