Abstract

To address the rise in tobacco use among college students, several national health organizations, including the American College Health Association, recommend that colleges enact smoking bans in and around all campus buildings, including student housing, and prohibit the sale, advertisement, and promotion of tobacco products on campus. Key informants at 50 US public universities, one from each state, were interviewed during the 2001/2002 academic year to assess the prevalence of these recommended policies. More than half (54%) of the colleges banned smoking in all campus buildings and student residences, 68% had no tobacco sales on campus, and 32% of the schools' newspapers did not accept tobacco advertising. Regional differences in adoption of these campus tobacco-control policies were present. Although this national sample of public universities had implemented some of the recommended policies, they must take further actions to comply fully with campus tobacco-control guidelines.  相似文献

In this article we examine the prevalence of and associations between sexual orientation–based verbal harassment and reported utilization of health services across levels of sexual orientation in a diverse sample of adult recipients of Los Angeles County–funded HIV-related health and social services. Thirty-two percent reported they had experienced verbal harassment, the majority (80.3%) of whom identified as lesbian, gay, or bisexual (LGB). Those who reported being verbally harassed received significantly more services overall than those who were not verbally harassed, and service utilization varied by sexual orientation. These findings inform future efforts to identify and assess social discrimination in health and social service settings.  相似文献

Though often conflated, informal physical exercise and organized athletic participation have very different implications for adolescent sexual risk outcomes. The purpose of this research is to disaggregate strenuous exercise from sports, examine how each is associated with sexual risk, and explain the observed differences using the conceptual lens of cultural resource theory. Using a nationally representative sample of over 16,000 public and private high school students, we employ logistic regression to test hypotheses about the gender-specific and race-specific effects of strenuous exercise and athletic participation on adolescent sexual risk behavior. The results show that both forms of physical activity buffer sexual risk for girls. Strenuous exercise is associated with increased odds of sexual risk for boys. Sports and race interact to influence boys' sexual risk outcomes: Athletic participation is associated with lowered odds of sexual risk for white male adolescents, but heightened odds of sexual risk for black male adolescents.  相似文献

During the 1960s and 1970s, the California Youth Authority embarked on a series of randomized field trials to test interventions for juvenile and young adult offenders. This article examines the institutional and political reasons why rigorous tests were adopted for such interventions as the Community Treatment Program. It also describes the effect these trials had on the agency and on California justice, as well as how the experimental method eventually became less often used in the Youth Authority. The authors explore some general reasons why this happened.  相似文献
