There is a need to investigate novel interventions that promote worksite physical activity and wellness. OBJECTIVE: The authors' purpose in this study was to evaluate the effectiveness of a 12-week walking program supplemented with a pedometer, computer educational program, and weekly e-mails. METHODS: College faculty and staff participated in a one-group pre-posttest study to determine whether the 12-week walking intervention had an effect on body mass index (BMI), blood pressure, blood glucose, and cholesterol. The authors also determined participant-perceived wellness effects. RESULTS: The authors observed differences between baseline and follow-up in BMI (p = .024), blood glucose (p = .06), and total cholesterol (p = .09). The program had a moderate effect on fitness, mood, health awareness, nutrition, and health. CONCLUSIONS: It is incumbent that experts develop innovative worksite physical activity and wellness programs. A pedometer-monitored walking program is one way that a worksite health initiative can improve the health and wellness of its employees and simultaneously reduce health-care costs. 相似文献

OBJECTIVE: Despite beliefs about weight gain in college, few researchers have evaluated this phenomenon. PARTICIPANTS: Participants were 18- to 31-year-old students at a midwestern university. The dependent variable was body mass index (BMI) change. METHODS: The authors extracted predictor variables from a Health Risk Appraisal. These included clinical, medical history, medical usage, medications, pain or chronic conditions, perceptual measures, and behavioral factors. The authors performed an ordinal regression technique separately by gender. RESULTS: No predictors were significant for men. Women in the BMI gain group were (1) more likely to consume alcohol, use maladaptive coping behaviors, eat foods low in fiber, and consume caffeine; and (2) less likely to be stress-free, to eat cruciferous vegetables, and to refrain from eating high-cholesterol foods. CONCLUSIONS: The lack of research on predictors of and interventions for reducing BMI gain among college students warrants more research. 相似文献

Unplanned sexual activity as a consequence of alcohol use: a prospective study of risk perceptions and alcohol use among college freshmen 总被引:1,自引:0,他引:1
OBJECTIVE: The authors' goal was to show how risk perceptions regarding unplanned sexual activity following alcohol use are prospectively related to subsequent alcohol consumption. PARTICIPANTS: Undergraduate students (N = 380) completed questionnaires at 2 time points during their freshman year. METHODS: In the middle of the academic year (T1), students estimated their risk of engaging in unplanned sex and reported their alcohol use during the previous term. Four months later (T2), they again reported alcohol use and indicated whether they had engaged in unplanned sex since T1. RESULTS: Students who consumed more alcohol at T1 rated their risk of unplanned sex more highly, suggesting relative accuracy. Those with higher risk perceptions consumed more alcohol at T2 (controlling for T1 use), suggesting that they maintained the high-risk behavior. Last, those who were unrealistically optimistic (ie, estimated low risk at T1 yet had unplanned sex by T2) reported greater alcohol use at T2. CONCLUSIONS: These findings highlight the role that risk perceptions regarding sexual activity may play in college students' alcohol use. 相似文献

Aging leads to significant losses in muscle mass, strength, and the ability to independently perform activities of daily living (ADL). Typically, standard resistance training (RT) has been used to reduce these losses in function by maintaining or even increasing muscle strength in older adults. Increasing strength does not necessarily, however, result in an increase in the ability to perform ADL. There is now research suggesting that muscle power is more closely associated with the performance of ADL than muscle strength is, so training for muscle power might lead to more beneficial results in functional performance. This review of studies investigating the effect of training on ADL performance in older adults indicated that standard RT is effective in increasing strength in older adults, but power training that contains high-velocity contractions might be a more optimal means of training older adults when the emphasis is on increasing the performance of ADL. 相似文献

This study examined the relationships between older women's comparison styles, physical self-perceptions, and functional fitness. Participants were community-dwelling women (N = 102, age 65-99) living in the mid-Atlantic region of the United States. Individuals were categorized as relying primarily on social comparisons, temporal comparisons, or a combination of both styles. Also of interest was whether individuals evaluated themselves positively or negatively when making comparisons. Participants who evaluated themselves positively as compared with others were found to have higher levels of physical self-perception. Analyses revealed that women who relied primarily on temporal comparisons had higher self-perceptions of their functional ability than those who relied on a combination of comparison styles. An avoidance of both temporal and social comparisons was also related to higher levels of physical self-perception. 相似文献

为民主而斗争是一项政治任务,也是一项教育任务.要促进充满活力的民主文化的产生,最根本的就是要认识到,教育必须被作为公共利益来看待.使高等教育沦为公司文化的附庸违反了教育支持和发展包含民主在内的公共空间的重要社会规则.从汤姆斯·杰佛逊到约翰·杜威,再到C.赖特·米尔斯,赞颂教育对于民主公共生活的根本的重要性成为一个悠久的传统. 相似文献
