ReviewBrief interventions to prevent sexually transmitted infections suitable for in-service use: A systematic review.
Sexually transmitted infections (STIs) are more common in young people and men who have sex with men (MSM) and effective in-service interventions are needed. ⋯ A small number of interventions which could be used, or adapted for use, in sexual health clinics were found to be effective in reducing STIs among young people and in promoting self-reported STI-risk behavior change in MSM.

Secondhand smoke exposure and susceptibility to initiating cigarette smoking among never-smoking students in selected African countries: Findings from the Global Youth Tobacco Survey.
Exposure to secondhand smoke (SHS) causes premature death and illness in non-smokers. We examined SHS exposure at home and in public places, as well as susceptibility to initiate cigarette smoking among never cigarette smokers. We used 2006-2011 Global Youth Tobacco Survey (GYTS) data from 29 African countries (56,967 students). ⋯ In many African countries in the study, a substantial proportion of students who never smoked are exposed to SHS at home and in public places. Majority of never smokers who were exposed to SHS at home and in public places had a higher prevalence of susceptibility to initiate smoking than those that were not exposed to SHS at home and in public places. Adoption and enforcement of smoke-free policies in public places and smoke-free rules at home could substantially contribute to reducing SHS exposure in many of these countries.

Evaluating a school-based fruit and vegetable co-op in low-income children: A quasi-experimental study.
The purpose of this study was to evaluate the effectiveness of a new school-based food co-op program, Brighter Bites (BB), to increase fruit and vegetable intake, and home nutrition environment among low-income 1st graders and their parents. This was a non-randomized controlled comparative effectiveness trial (2013-2015). Six schools received BB (n=407 parent-child dyads); six comparison schools implemented a coordinated school health program (n=310 parent-child dyads) in Houston, Texas, 2013-2015. ⋯ Among parents, there were significant increases in fruit consumed (P=0.032); vegetable intake increased baseline to midpoint but not post-intervention. Among BB families, there were significant improvements in the home environment including understanding and usage of nutrition facts labels to make food purchases (P<0.05), frequency of cooking (P=0.007), rules and practices regarding eating family meals (P=0.022), serving fruits (P=0.005) and vegetables (P=0.028) at meals, and limiting portion sizes (P=0.016). In conclusion, a school-based food co-op model shows promising results in improving dietary habits and home nutrition environment among low-income families.

The healthfulness of food and beverage purchases after the federal food package revisions: The case of two New England states.
In 2009, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) implemented new food packages to improve dietary intake among WIC participants. This paper examines how the healthfulness of food purchases among low-income households changed following this reform. ⋯ After the WIC revisions, the healthfulness of participant purchases improved, particularly for beverages. Efforts to encourage healthy eating by people receiving federal food assistance are paying off.

Comparative StudyTobacco use disparities by racial/ethnic groups: California compared to the United States.
Racial/ethnic disparities in cigarette use and cessation persist. This study compared cigarette consumption and former smoking trends in California (CA) with the rest of the United States (US) by racial/ethnic categories of non-Hispanic White, Black, Hispanic/Latino, and Asian/Pacific Islander groups. Data were analyzed from the 1992 to 2011 Tobacco Use Supplement to the Current Population Survey. ⋯ Data were stratified by race/ethnicity and the patterns shown were mostly consistent with CA performing statistically better than their US counterparts with the exception of Black LITS and Asian/Pacific Islander former smokers. California's success in reducing tobacco use disparities may serve as a prime example of tobacco control policy for the country. CA and the US will need to continue to address tobacco use and cessation in the context of the growing diversity of the population.
