Abstract

In 1999, the Harvard School of Public Health College Alcohol Study resurveyed colleges that participated in the 1993 and 1997 surveys. Responses to mail questionnaires from more than 14 000 students at 119 nationally representative 4-year colleges in 39 states were compared with responses received in 1997 and 1993. Two of 5 students (44%) were binge drinkers in 1999, the same rate as in 1993. However, both abstention and frequent binge-drinking rates increased significantly. In 1999, 19% were abstainers, and 23% were frequent binge drinkers. As before, binge drinkers, and particularly frequent binge drinkers, were more likely than other students to experience alcohol-related problems. At colleges with high binge-drinking rates, students who did not binge drink continued to be at higher risk of encountering the secondhand effects of others' heavy drinking. The continuing high level of binge drinking is discussed in the context of the heightened attention and increased actions at colleges. Although it may take more time for interventions to take effect, the actions college health providers have undertaken thus far may not be a sufficient response.  相似文献

African-American youth growing up in dangerous, deprived homes and communities are at great risk of developing impaired relationship capabilities, which disadvantages them further in the workplace and in their personal lives. While after-school programs have well-documented positive effects, researchers have called for better understanding of improving youths’ engagement in services and their constructive relationship skills. Here, we report on a project using participatory action methods to engage poverty-level African-American youth in developing a leadership development program they would find most meaningful. Stand Up Help Out (SUHO) gave youth three layers of caregiving experience: receiving care from instructors, giving and receiving care from peers, and providing care through constructive community action initiatives and mentoring elementary school children. Findings were that: (1) participation and retention of youth in SUHO were considerably higher than national averages; (2) youth reported that SUHO made it possible for them to have better relationships as friends, romantic partners, and in academic settings, and they looked forward to being better parents, (3) youth developed positive peer relationships despite a context of mistrust and gang violence, (4) youth actively sought out relationships with caring adults and identified what was most meaningful in those relationships, and (5) youth deeply valued the opportunity to develop their ability to care for others.  相似文献

Abstract

To identify factors that influence condom use and the risk of acquiring sexually transmitted diseases (STDs) among African American college women, the authors surveyed a sample of 123 sexually experienced undergraduate women at a state university. The college women who were older, had initiated sex earlier, or had more recent sexual partners were more likely than others in the study to report a history of an STD. The findings have implications for prevention and intervention programs for African American college women.  相似文献

Abstract

Objective: To examine whether young adult cigarette smokers who were in the precontemplation and contemplation stages of change for smoking cessation would differ in their evaluations of vignettes depicting 2 types of physician advice. Participants: Fifty-seven young adult cigarette smokers who were undergraduate students (49.1% female, mean age = 20.4 years) attending an urban university. Methods: Participants evaluated 2 written vignettes. Both vignettes depicted physicians using patient-centered communication styles. One vignette depicted a physician giving a patient direct advice to quit smoking and the other a physician using a motivational style of advice. Data were collected from September 2004 through May 2005. Results: Participants rated the motivational advice vignette as significantly more favorable compared to the direct advice vignette on all assessed dimensions (global satisfaction, general satisfaction, physician affective style, physician technical style, and physician communication style). Conclusion: Smokers preferred the motivational advice style to simple patent-centered advice.  相似文献

Abstract

Objective: To examine patterns of binge drinking and changes in drinking patterns among Chinese university students. Participants and Methods: Responses to an anonymous questionnaire were compared between a random sample of 411 second year Chinese undergraduate students in 2006 and 2,630 first year students from the previous year. Students reporting any symptoms of alcohol abuse were classified as alcohol abusers whereas those reporting repeated inability to curtail use were categorized as alcohol dependent. Results: After 1 year of university, greatly increased rates of past-month drinking of different degrees were found in both genders. Binge drinking among second year undergraduates was significantly correlated with male gender, living in a student residence hall, smoking, drinking to relieve stress, and having friends who frequently drank. Conclusions: Alcohol misuse is a health hazard to Chinese students in a university environment. Proactive policies aimed at preventing harmful alcohol use should be considered by university authorities.  相似文献

Abstract

Objective: Although previous research has suggested that college housing impacts student behavior and outcomes, recent research linking college housing to risk-taking has been limited. In this study, we investigate if patterns of risk behavior differ based on the type of college housing environment students reside in. Participants: This study utilizes 510 college students living in on-campus college housing. Methods: Students were recruited from 5 college sites across the United States. Participants responded to survey items online that measured current risk-taking behaviors such as binge drinking and sexual activity. Results: After controlling for an assortment of demographic and psychological variables, results indicated that students living in co-ed housing were more likely than students living in gender-specific housing to binge drink and consume alcohol, have more permissive sexual attitudes, and have more recent sexual partners. Conclusions: On-campus housing environments impact college student risk behaviors. Implications are discussed in light of the decline of in loco parentis on most college campuses.  相似文献

Abstract. Ecstasy (MDMA) has been added to the spectrum of illicit drugs used by college students. In this study, the authors estimated the prevalence of ecstasy use within a large college student sample and investigated the polydrug-use history of those ecstasy users. They administered an anonymous questionnaire to college students (N = 1,206) in classrooms at a large university in the mid-Atlantic United States. The overall student response rate was 91%. Nine percent of the sample reported lifetime ecstasy use. Because 98% of ecstasy users had used marijuana, the authors compared polydrug use between ecstasy users and individuals who had used marijuana but not ecstasy. Ecstasy users, as compared with these marijuana users, were significantly more likely to have used inhalants (38% vs. 10%), LSD (38% vs. 5%), cocaine (46% vs 2%), and heroin (17% vs 1%) in the past year. Significant polydrug use among college student ecstasy users has important implications for their substance abuse treatment.  相似文献

Abstract

College communities are increasingly being called upon to institute date rape prevention programs. This article describes a mixed-gender workshop sponsored by a university's Program for Rape Education and Prevention that was given to more than 1,400 undergraduate students in more than 80 presentations. In order to guide modifications of the workshop, formative evaluation data collected from 330 male (mean age 20.3 years) and 314 female (mean age 20.5 years) university students were collected. Results were largely positive. Despite the sensitive nature of the topic, only 10.2% of the men and 8.2% of the women reported being uncomfortable discussing date rape in mixed-gender groups. Furthermore, students were virtually unanimous in their agreement that date rape is a topic worthy of a workshop.  相似文献
