Stigma, discrimination and violence contribute to health disparities among sexual minorities. Lesbian, bisexual and queer (LBQ) women experience sexual violence at similar or higher rates than heterosexual women.

The coalition literature recognizes context (geography, demographics and history) as a variable of interest, yet few coalition evaluation studies have focused on it. This study explores the association between geographic context and structures (e.g. member type) with functional characteristics (e.g. decision making or levels of conflict) in a…

Little research has assessed the fidelity, adaptation or integrity of activities implemented within community-based obesity prevention initiatives. To address this gap, a mixed-method process evaluation was undertaken in the context of the South Australian Obesity Prevention and Lifestyle (OPAL) initiative. An ecological coding procedure assessed…

This study analyzed psychosocial predictors of the Theory of Planned Behavior (TPB) and Self-Determination Theory (SDT) and evaluated their associations with short- and long-term moderate plus vigorous physical activity (MVPA) and lifestyle physical activity (PA) outcomes in women who underwent a weight-management program. 221 participants (age…

A unique dataset of 149 240 university-bound senior high school students from 2009 to 2011 was constructed by merging two nationwide administrative…

The aim was to better understand structural factors associated with uptake of automated tailored interventions for smoking cessation. In a prospective randomized controlled trial with interventions only offered, not mandated, participants were randomized based on the following: web-based expert system (QuitCoach); text messaging program (onQ);…

The purpose of this study was to determine: (i) the effect of schools' baseline community readiness (CR) on youth physical activity (PA) at recess prior to the Ready for Recess intervention; (ii) if changes in PA due to the intervention were explained by baseline CR and (iii) if specific components of the intervention altered an association…

This study explores interactions of perceived safety and social neighborhood factors with psychosocial cognitions for leisure-time walking. Cross-sectional data were obtained from residents (age 25-75…

Controversy surrounding an autism-vaccine link has elicited considerable news media attention.

To investigate how this reporting style influences judgments of vaccine…

Hookah tobacco smoking is increasing among US college students, including those who would not otherwise use tobacco. Part of hookah's appeal is attributed to the perception that hookah is less harmful than cigarettes. The aims of this study were to assess knowledge of harmful exposures associated with hookah smoking relative to cigarette smoking…
