Abstract

Objectives and Participants: Changes in body weight, composition, and size were examined in college freshmen at the beginning (initial, n = 240) and end of fall semester 2007 (n = 214) and the end of spring semester 2008 (n = 205). Methods: Height, weight, body composition, and waist and hip measurements were assessed. Results: Mean weight, body mass index (BMI), absolute and percent body fat all increased significantly over fall semester and the academic year. About 31% of freshmen lost ≥5 lbs. Mean academic year weight gain was 2.6 lbs (entire group) and 6.0 lbs (weight gainers); body fat increased by 4.4 lbs in the weight gainers. A significant correlation (r = .509) was found between weight change and waist circumference change, but not between weight change and waist to hip ratio change. Conclusions: Freshmen weight gain is associated with increases in body fat and waist circumference, which may be troublesome should the trend continue throughout college.  相似文献

Abstract

Objectives: To examine the impact of downward social comparison and the “known partner is a safe partner” heuristic on college students’ sexual decisions. Participants: One hundred-eighty heterosexual or bisexual undergraduate college students. Methods: Participants read dating vignettes that varied on perspective and familiarity and then rated the likelihood the couple would engage in sexual intercourse and use a condom. Results: There were no differences in rated likelihood based on familiarity, suggesting that the students did not view the 2 partner types as significantly different. Students rated the likelihood of sexual intercourse lower and condom use higher when the vignette was presented from the second person perspective. Conclusions: The students’ use of downward social comparison is consistent with the “better than average effect,” suggesting that the students perceive their own behavior as safe. The implication is that safer sex messages might be most effective if they focus on what students will gain by practicing safer sex behaviors, not just avoidance of a risk behavior.  相似文献

Abstract

Objective: In order to address increasing health care costs associated with obesity, this study sought to determine prevalence of overweight and obesity and examine eating behaviors, food choices, health beliefs, and attitudes of university employees. Participants and Methods: An online survey was distributed to > 3,800 faculty and staff at a large public metropolitan university in Winter 2008. Results: Almost half (48%) of 806 respondents were classified as overweight or obese. Compared to those with normal weights, overweight and obese respondents consumed fewer fruits and vegetables (p < .05), were less confident in making healthful food choices (p < .001), and were more influenced by food choices available in on-campus dining facilities (p < .05). Conclusions: Obesity among university employees warrants attention. Because these employees have less self-efficacy and consume less healthful diets than their normal weight colleagues, universities need to improve on-campus access to healthful foods.  相似文献

Abstract

In April and May 1989, the authors surveyed a sample of students enrolled on four college campuses in New Jersey (N ? 923) concerning their HIV transmission-related behavior, knowledge, and a variety of conceptual variables taken primarily from social cognitive theory that were thought to be potentially predictive of safer sexual behavior. Analyses of sexually active, unmarried students' responses indicated that men expected more negative outcomes of condom use and were more likely to have sexual intercourse while under the influence of alcohol or other drugs, whereas women reported higher perceived self-efficacy to practice safer sex. Regression analyses indicated that, among the factors assessed, stronger perceptions of self-efficacy to engage in safer behavior, expecting fewer negative outcomes of condom use, and less frequency of sex in conjuction with alcohol or other drug use significantly predicted safer sexual behavior. Enhanced self-efficacy to discuss personal history with a new partner was associated with a greater number of risky encounters. Implications of these findings for intervention efforts with students are discussed.  相似文献

Abstract

Objectives: To (1) assess cycling-related questions that have been added to the electronic version of the American College Health Association National College Health Assessment II (ACHA-NCHA), (2) examine cycling prevalence, and (3) identify predictors of cycling in college students. Participants: Predominately female (69%), undergraduate (89%), and white (85%) students (N = 949) from a large, urban, northwestern, bicycle-friendly university completed the electronic version of the ACHA-NCHA II. Methods: Thirty cycling-related questions were added to the ACHA-NCHA II and a subsample of questions was analyzed. Results: Cycling questions added to the ACHA-NCHA II scale were reliable and valid, based on the psychometric data analysis. More than half (59%) of this sample cycled; of those, 58% cycled for transportation and 44% for recreation. Facilitators and barriers to cycling were different for cycling in general and cycling for transportation. Conclusions: Cycling questions added to the ACHA-NCHA II can be utilized to enhance knowledge relative to cycling on college campuses.  相似文献

Abstract

Objective: Examine the co-occurrence of alcohol consumption, physical activity, and disordered eating behaviors via a drunkorexia perspective. Participants: Nationally representative sample (n = 22,488) of college students completing the Fall 2008 National College Health Assessment. Methods: Hierarchical logistic regression was employed to determine if physical activity and disordered eating behaviors uniquely predicted binge drinking, while controlling for age, race, gender, year in college, Greek membership, and place of residence. Results: Physical activity and disordered eating made unique, statistically significant contributions. Moreover, including physical activity and disordered eating behaviors allowed for the correct classification of an additional 431 cases (ie, binge drinkers) over and above the predictive ability of the covariate-only model. Conclusions: Findings corroborate prior research indicating highly active college students are more likely to binge drink than their nonactive peers, and highlight the potential of a drunkorexia perspective in explaining the counterintuitive alcohol–activity association among college students.  相似文献

Elder Abuse:     
Perpetrator and incident characteristics were studied in regard to incidents of emotional, physical, and sexual mistreatment of older adults (age 60+) in a national sample of older men and women. Random digit dialing across geographic strata was used to compile a nationally representative sample; computer assisted telephone interviewing was used to standardize collection of demographic, mistreatment, and perpetrator and incident characteristics data. The final sample size consisted of 5,777 older adults. Approximately one in ten adults reported at least one form of mistreatment, and the majority of incidents were not reported to authorities. Perpetrators of physical mistreatment against men had more “pathological” characteristics compared to perpetrators of physical mistreatment against women. Perpetrators of physical mistreatment (compared to emotional and sexual mistreatment) also evidenced increased likelihood of legal problems, psychological treatment, substance use during incident, living with the victim, and being related to the victim. Implications for future research and social policy are discussed.  相似文献

We know relatively little about the definitions and perceptions of elder abuse held by marginalized groups of older adults in Canada. The current study used focus group methodology to explore perceptions of elder abuse among marginalized groups such as Aboriginal persons, immigrants, refugees, and lesbians. We found both similarities and differences in perceptions of elder abuse across groups. Groups identified traditional forms of elder abuse (i.e., physical, sexual, psychological/emotional, financial abuse, and neglect) as well as less frequently identified types of abuse such as disrespect and government or systemic abuse. Groups also discussed issues related to immigrant sponsorship arrangements and abuse in nursing homes.  相似文献
