AbstractU.S. women are ageing. This is causing rises in osteoporosis prevalence and risk of fracture with related increases in health care costs. Replacing sedentary time with light physical activity may represent a cost effective public health solution to osteoporosis in elderly women. The National Health and Nutrition Examination Survey conducted over the period 2003–2006 provided cross-sectional data on bone mineral density and objectively assessed physical activity among 1,052 women aged 50–85 years old. Substitution analysis was applied to estimate increased bone mineral density and reduced osteoporosis for those women replacing 30?min of sedentary time with an equivalent amount of light physical activity. Substitution of 30?min of sedentary time with an equal amount of light physical activity was associated with increased bone mineral density of about 3?mg/cm2 and a 12% reduced risk of osteoporosis in the spine. When considering overweight women and women over 65 years of age, this association was reinforced and it extended to the pelvis, legs and trunk, resulting in a consistent bone mineral density increase of about 3–6?mg/cm2. The substitution of 30?min of sedentary time with an equal amount of light physical activity appears a possible primary prevention method to reduce osteoporosis and related increases in risk of fracture, mortality, and health care costs in women over 50 years old. 相似文献

We examined the relationship between implicit and explicit “exerciser” and “sedentary” self-identity when activated by stereotypes. Undergraduate participants (N = 141) wrote essays about university students who either liked to exercise or engage in sedentary activities. This was followed by an implicit identity task and an explicit measure of exercise self-identity. Results showed that implicit and explicit exerciser identities were not highly correlated. There were also no significant prime effects, but women showed greater implicit sedentary identity, whereas men showed greater implicit exercise identity. This research suggests that implicit exercise-related identity is a distinct construct from explicit exercise identity. The results also reflect responses to societal pressures for women to be thin and for men to be strong, when free of self-presentational bias. 相似文献

AbstractOver 12 weeks, supervised physical activity (PA) interventions have demonstrated improvements in morphological and health parameters, whereas community walking programmes have not. The present study piloted a self-guided programme for promoting PA and reducing sedentary behaviour in overweight individuals and measured its effect on a range of health outcomes. Six male and 16 female sedentary adults aged 48.5 ± 5.5 years with body mass index (BMI) 33.4 ± 6.3 kg m?2 were assessed for anthropometric variables, blood pressure, functional capacity, well-being and fatigue. After an exercise consultation, participants pursued their own activity and monitored PA points weekly. At baseline, mid-point and 12 weeks, eight participants wore activity monitors, and all participants undertook a 5-day food diary to monitor dietary intake. In 17 completers, mass, BMI, sit-to-stand, physical and general fatigue had improved by 6 weeks. By 12 weeks, waist, sagittal abdominal diameter (SAD), diastolic blood pressure, well-being and most fatigue dimensions had also improved. Throughout the intervention, PA was stable, energy intake and lying time decreased and standing time increased; thus, changes in both energy intake and expenditure explain the health-related outcomes. Observed changes in function, fatigue and quality of life are consistent with visceral fat loss and can occur at levels of weight loss which may not be considered clinically significant. 相似文献

运用文献资料、问卷调查、数理统计等方法,对我国中部地区农村居民生活方式对健康的影响进行研究。通过对13个相关维度分析后发现：①相关地区的医疗卫生资源和保障状况比较好,医疗卫生保健知识普及宣传力度与5年前相比,已经得到了很大的改善,但还需要进一步增强。②在生存方式指标“个人收入”和生活方式指标“吸烟、饮酒、饮食和睡眠质量”等方面对健康的影响分析中,没有发现有显著性差异。③在生存方式指标“生活环境污染情况”“参加生产劳动时间”“不同生活地域”和生活方式指标“受教育程度”“婚姻和家庭状况”“是否参加体育锻炼”等对健康的影响分析中,均发现有显著性差异,说明这些因素与该人群的健康有很大的相关性。建议：①政府应进一步加强对农村医疗卫生、健康保健等知识的普及宣传,使居民形成“预防为主、治疗为辅”的正确健康观念。②加强农村体育健身软硬件设施和系统的建立,形成科学、合理的健身系统网络。③加大对地方环境污染的整治工作,努力做到将污染危害程度降到最低。④提高农村人口的受教育水平,进而提高他们的保健认知水平和生活质量 相似文献

澳门社区体育的发展模式 总被引：13，自引：1，他引：12
对建立符合澳门地区社会水平与澳门实际情况的“社区体育发展模式”进行了研究。研究认为：(1)在构建澳门社区体育发展模式的过程中，首先应完善社区体育组织体系。建立组织网络系统，充分发挥各级社区体育组织的功能作用，提高组织管理水平，建立一支稳定的、具有一定专业水平的社区体育指导队伍；(2)目前澳门劳工阶层与平民大众因受各种因素、条件的影响和限制，不能积极参加或无法参加社区体育活动：(3)体育场地设施的建设与使用，未能配合到社区体育的发展。对现有的体育资源，应予充分利用和开发；(4)加强与其它体育形态的合作，在互补的基础上相互支持，以求共同发展。 相似文献
