INTRODUCTION AND AIMS
Alcohol and substance use can have negative health consequences among both human immunodeficiency virus (HIV)-positive and -negative individuals, and are associated with behaviors that facilitate HIV transmission and acquisition. The relationship of substance use and HIV is well documented among key populations at risk for HIV. However, although transwomen (male-to-female transgender) are disproportionately impacted by HIV, this overlap remains understudied in this population. We sought to evaluate the association between HIV, alcohol and substance use among transwomen.
DESIGN AND METHODS
We conducted a secondary data analysis of Respondent Driven Sampling study which collected information on self-reported alcohol and substance use among 314 transwomen. We used multivariable logistic regression to assess relationship between HIV infection and classes and patterns of alcohol and substance use.
RESULTS
We found that 58% of transwomen used alcohol, and 43.3% used substances. The most common substances used were: marijuana (29%), methamphetamine (20.1%), crack cocaine (13.4%), and 'club drugs' (13.1%). Transwomen who reported any methamphetamine use [adjusted odds ratio (AOR) 3.02 (95% confidence interval (CI) = 1.51-6.02)], methamphetamine use before or during anal intercourse [AOR 3.27 (95% CI = 1.58-6.77)], and at least weekly methamphetamine use [AOR 3.89 (95% CI = 1.64-9.23)] had significantly greater odds of testing positive for HIV.
DISCUSSION AND CONCLUSIONS
Transfemales have high prevalence of alcohol and substance use; those tested positive for HIV used significantly more methamphetamine in general, and in conjunction with sex. Given the disproportionate prevalence of HIV and substance use in this population, interventions aimed at addressing both substance use and HIV risk among transwomen are urgently needed.

INTRODUCTION
The extent of obesity prevention activities conducted by local health departments (LHDs) varies widely. The purpose of this qualitative study was to characterize how state obesity prevention program directors perceived the role of LHDs in obesity prevention and factors that impact LHDs' success in obesity prevention.
METHODS
From June 2011 through August 2011, we conducted 28 semistructured interviews with directors of federally funded obesity prevention programs at 22 state and regional health departments. Interviews were transcribed verbatim, coded, and analyzed to identify recurring themes and key quotations.
RESULTS
Main themes focused on the roles of LHDs in local policy and environmental change and on the barriers and facilitators to LHD success. The role LHDs play in obesity prevention varied across states but generally reflected governance structure (decentralized vs centralized). Barriers to local prevention efforts included competing priorities, lack of local capacity, siloed public health structures, and a lack of local engagement in policy and environmental change. Structures and processes that facilitated prevention were having state support (eg, resources, technical assistance), dedicated staff, strong communication networks, and a robust community health assessment and planning process.
CONCLUSIONS
These findings provide insight into successful strategies state and local practitioners are using to implement innovative (and evidence-informed) community-based interventions. The change in the nature of obesity prevention requires a rethinking of the state-local relationship, especially in centralized states.
