Abstract

Objective: To explore gender differences regarding weight management behaviors of college drinkers. Participants: Nationally representative sample of college students from the fall 2008 American College Health Association's National College Health Assessment II (N = 26,062 students). Methods: Structural equation modeling was used to examine potential gender differences in associations among exercise, weight loss behaviors, and alcohol use. Results: Critical ratio tests revealed that associations between exercise and weight loss behaviors were more strongly correlated among females as compared with males. For females, there was a small negative association between exercise and drinking behaviors; in contrast, for males, there was a positive relationship between exercise and alcohol use. Weight loss behaviors were positively associated with drinking for both female and male students; however, the association was significantly stronger for females. Conclusions: This investigation furthers previous research on drunkorexia and also sheds additional light on the gender-based differences in weight management behaviors of drinkers.  相似文献

Abstract

Objective: Determine rate of college student alcohol-related vehicular traffic fatalities in Virginia during 2007. Participants: Undergraduates at colleges and universities in Virginia. Methods: Institutions with membership in the American College Health Association were invited to participate in a survey. Data collected from institutional reports of student deaths due to vehicular accidents. Results: Twenty-four institutions were invited to participate. Sixteen responded (response rate = 67%), comprising total enrollment of 117,100 for 17- to 24-year-olds (56% of total college population in state). Five traffic deaths were reported, representing 4.3 deaths per 100,000 students. Based on statewide statistics that estimate alcohol contributes to 38.9% of traffic deaths, rate of alcohol-related motor vehicle deaths is 1.7 deaths per 100,000 college students in Virginia, which is 89% lower than leading national estimates. Conclusions: These findings suggest that past estimates of alcohol-related vehicular deaths among college students are overstated.  相似文献

Abstract

College students' cigarette smoking rose dramatically during the 1990s. Little is known about what colleges do to address the problem. Health center directors at 393 4-year US colleges provided information (response rate: 65.1%) about college policies addressing smoking and the availability of smoking cessation programs. Of the health center directors surveyed, 85% considered students' smoking a problem; yet only 81% of colleges prohibit smoking in all public areas and only 27% ban smoking in all indoor areas, including students' rooms in dormitories and in private offices. More than 40% of the respondents reported that their schools did not offer smoking cessation programs and that the demand for existing program was low. Colleges need to do more to discourage student tobacco use. Recommended actions include campus-wide no-smoking policies that apply to student residences and identification of new ways of providing smoking prevention and cessation services.  相似文献

ABSTRACT

Experiences of African mothers with HIV can inform the development of services to prevent HIV transmission to children. A small qualitative study was conducted in Tanzania with six openly HIV-positive women. They suggest that counseling and HIV testing additionally benefit the mother beyond reducing HIV transmission to her child. They recommend that testing of couples would allow them to make plans and informed choices together concerning sexual behavior, childbearing, and prevention of HIV transmission to children.  相似文献

Abstract

Objective: To compare the efficacy of 2 human papillomavirus (HPV) educational interventions on increasing HPV knowledge and vaccination intentions in college students. Participants: Male (n = 60) and female (n = 140) undergraduates (M age = 20.4, SD = 2.3) recruited from a university in Montreal, Quebec, Canada, from October 2009 to March 2010. Methods: Using theory-based interventions, participants were randomly assigned to either a written HPV pamphlet, an HPV video, or a control. HPV knowledge and vaccination intentions were assessed pre and postintervention. Results: Low baseline knowledge and intentions were found across groups. Postintervention, participants in the written and video interventions had significantly higher knowledge and intentions than the control. No differences were found between written and video interventions on knowledge or intentions. Conclusion: This study, a first in comparing HPV educational formats, suggests that both written and video interventions are equally effective in educating about HPV and increasing young adults’ vaccination intentions.  相似文献

Abstract

The extremely low prevalence of steroid use among college students makes it virtually impossible to conduct analyses on any single college campus. By studying a cohort of 58,625 college students from 78 institutions that administered the Core Alcohol and Drug Survey in 1990 and 1991, a critical mass of 175 users on which it was possible to conduct statistical analyses was identified. Compared with a randomly selected group of nonusers, the steroid users reported consuming dramatically more alcohol and demonstrated higher rates of binge drinking. In addition, a significantly higher percentage of steroid users reported using tobacco, marijuana, cocaine, amphetamines, sedatives, hallucinogens, opiates, inhalants, and designer drugs. A higher percentage of steroid users than nonusers also reported experiencing negative consequences as a result of substance abuse, and a greater percentage of the steroid users reported family histories of abuse of alcohol and other drugs. Implications from the standpoint of student development are discussed.  相似文献

When a child is born with a disability, the caregiver's life is altered. With the numerous challenges caring for a child with disability brings, caregivers may feel devastated. These challenges often result in increased stress on the caregiver, which, in many cases, places the child at risk for maltreatment. The purpose of this study is to explore issues a caregiver faces when caring for his or her child. In this contextual analysis, seven caregivers of children with moderate-to-severe disabilities completed a questionnaire, were interviewed individually, and assisted the researcher in constructing an ecomap of their current living environment. Content from the interviews was analyzed and several themes developed from the data. Implications for clinical practice and future research ideas are discussed.  相似文献
