Abstract

Fitness levels of American youth have shown a marked decline in the last decade, according to recent studies. To determine whether such a tendency persists for entering college students, the authors evaluated 115 male and 143 female students for performance on the following fitness-related variables: (1) maximal oxygen consumption (estimated from Astrand cycling protocol), (2) body composition (skin-fold techniques), (3) muscle endurance (sit-up protocol), (4) muscle strength (bench-press protocol), and (5) joint flexibility (upper and lower body protocols).

Although neither men nor women exhibited high levels of cardiorespiratory fitness, the women in the study showed higher relative levels than their male counterparts. Both groups showed excellent levels of muscle strength (compared with normative standards), but they achieved only an average standard for muscle endurance. Findings of relatively low levels of cardiovascular fitness compared with levels of muscle strength, particularly in men, seem to be a reflection of an inappropriate concentration of physical activity.  相似文献

Abstract

Objectives: This study sought to describe self-reported barriers to professional help seeking among college students who are at elevated suicide risk and determine if these barriers vary by demographic and clinical characteristics. Participants: Participants were 165 non–treatment seekers recruited as part of a Web-based treatment linkage intervention for college students at elevated suicide risk (from September 2010 through December 2011). Methods: Data were collected using Web-based questionnaires. Two coders coded students’ responses to an open-ended question about reasons for not seeking professional help. Results: The most commonly reported barriers included perception that treatment is not needed (66%), lack of time (26.8%), and preference for self-management (18%). Stigma was mentioned by only 12% of students. There were notable differences based on gender, race, and severity of depression and alcohol abuse. Conclusions: Efforts aimed at reaching students at elevated risk for suicidal behavior should be particularly sensitive to these commonly described barriers.  相似文献

Abstract

Objective: Small-scale pilot testing of supplementing a required college health-related fitness course with a cognitive-behavioral exercise-support protocol (The Coach Approach). Participants: Three classes were randomly assigned to Usual processes (n = 32), Coach Approach–supplemented: Mid-size Groups (n = 32), and Coach Approach–supplemented: Small Groups (n = 34) conditions. Methods: Repeated-measures analyses of variance (ANOVAs) assessed overall and between-class changes in the behavioral/physiological factors of exercise, fruit/vegetable intake, and body mass index (BMI); and the psychosocial factors of self-regulation, exercise self-efficacy, mood, and body satisfaction. Dependent t tests evaluated within-class changes. Multiple regression analyses tested prediction of exercise by changes in self-regulation, self-efficacy, and mood. Results: Significant improvements in self-regulation and fruit/vegetable intake were found in all classes. The Coach Approach–supplemented classes demonstrated significant increases in exercise. Significant improvements in BMI, self-efficacy, and body satisfaction were found in only The Coach Approach–supplemented: Small Groups class. Psychosocial changes predicted increased exercise. Self-regulation was the strongest contributor. Conclusions: Overall, results were positive and warrant more comprehensive testing.  相似文献

Despite the rapid growth of the elderly African American population in the U.S., elder abuse and neglect in African American families continue to be underdeveloped areas of study. This article presents an ecological and culturally informed framework for the study of elder abuse in African American populations. The model was developed based on Bronfenbrenner's Human Ecological Theory. The model identifies risk factors associated with different systems that have an influence on the lives of African American families. Cultural protective factors also are identified in the model. The model is intended to provide an understanding of elder abuse and neglect in African American families by considering the influence of contextual factors such as the legacy of slavery, social exclusion, and structural segregation and racism. Specific suggestions for practice are proposed according to cultural strengths of African American communities as well as the ecological premises of the model.  相似文献

Ageist attitudes have been identified across different industries. The nursing profession has a high proportion of older workers. As this facilitates regular contact with, as well as exposure to, older nurses, it may be expected to show less ageism. This study investigated 163 Western Australian nursing recruiters' attitudes toward older nurses. Results showed clear evidence of both negative and positive stereotyping of older nurses. Nursing recruiters indicated that they would be more than likely to hire older nurses and that age was less relevant in making hiring decisions. These findings suggest that enhancing the employability of older workers does not necessarily change ageist attitudes. This is relevant to policy formulation, attitude change interventions, and the well-being of older workers.  相似文献

Using the newly created Freedom Poverty Measure, a multidimensional measure of poverty, it can be seen that there were 534,700 individuals who were in freedom poverty, who had either poor health or poor education in addition to having low incomes. This multidimensional disadvantage would not normally be captured by single measures of poverty, such as income poverty measures. Men were significantly less likely to be in freedom poverty than women (OR = 0.63, 95% CI: 0.54–0.74, p < .0001), and the proportion of individuals in freedom poverty increased with age, with those older than 85 being 2.3 times more likely to be in freedom poverty than those aged 65 to 69 years (95% CI: 1.73–3.11, p < .0001). Policy responses to address the marginalization of disadvantaged older people should take a multidisciplinary approach, addressing health inequalities in particular, not just low income.  相似文献

This article challenges the profession's accreditation requirement that social work field placements must have a social worker as supervisor. The author argues that the profession's stated commitment to social and economic justice can best be served if the profession broadens the definition of what constitutes good social work practicum supervision. With support from schools of social work, people in our communities from different disciplines and backgrounds engaged in progressive justice work, can provide social work students with valuable experiences and in turn enrich the social work curriculum.  相似文献

我国经济发展的不平衡导致社会保障财政支出存在地区间差异。2001至2010年我国人均社会保障支出呈现的周期性变化,近年东、中、西和东北四大地带内的差异是中国社会保障财政支出差异性的主要原因,尤以东部地带差异性显著。针对上述地区差异,利用谱系聚类方法,按社会保障财政能力的相似性将我国各地区分为四类。根据这一分类建议:我国要进一步完善社会保障补助制度,在增加社会保障财政支出的同时,发展各地区经济,平衡各地区之间的财政能力,实现全国社会保障均衡发展。  相似文献

Although there are many similarities between the young women Susie Orbach describes and their counterparts in the northeastern United States, there are also complexities and multiplicities in their behavior and expression of aggression, their experience of themselves and of each other, that require us to reach beyond a comfortable intergenerational grasp. These daughters of women who came of age in the feminist movement are members of their own quite globalized youth culture with its own construction of “girls” in an era when aggression is everywhere more explicit and relationships with parents have been shaped by economic and social changes. We do not really know how concepts, like merged attachment, that were so critical to our liberation and coming of age, are relevant to the experience of these young women. It is a question to explore in a cultural context that is more familiar to them than it is to us, their parents.  相似文献

Scholarly publication is becoming increasingly important in social work. Not only does publication reflect the knowledge development effort of the profession, but it apparently positively affects the careers of the authors. In the current study, the authors evaluated the scholarly productivity of 284 randomly selected doctoral graduates from 30 social work programs. The authors accumulated and aggregated for each program counts of publications appearing in the Source Index of the Social Sciences Citation Index.Findings indicated that the level of article productivity among doctoral graduates was normative. In addition, the productivity of doctoral program faculty was found to be related to the productivity of the program’s doctoral graduates. The authors suggest that perhaps productive faculty provide positive role models to their students; this mentoring relationship contributes to graduate productivity outcomes.  相似文献
