背景：尽管人们知道久坐对健康有很多好处，但许多美国成年人仍然久坐不动。对体育活动决定因素的研究表明，社会支持是最强的相关性之一，但对中老年妇女这一重要亚群的关系知之甚少。目的：本研究的目的是在全国少数民族妇女样本中评估体育活动与社会支持的关系。这些措施的一个独特之处在于包括了繁重的家务劳动和职业体力活动。美国妇女决定因素研究于1996年至1987年进行。该调查是一项改进的随机抽样电话调查，共有2912名黑人、西班牙裔、美洲印第安人；40岁及以上的阿拉斯加原住民和白人女性。以体力活动社会支持（PASS）总分作为自变量进行logistic回归分析。四项体力活动水平测量作为因变量。一项单独的分析已经完成，以区分PASS来自朋友和PASS来自亲戚。种族的潜在混淆效应。在模型中对婚姻状况、年龄、收入和受教育程度进行评价和调整。西班牙裔女性比其他种族/族裔群体更有可能获得高分。优势比表明，即使在调整了种族/民族因素后，高PASS水平的受试者比低支持水平的受试者更不可能久坐。虽然社会支持水平和身体活动之间存在显著关联，但“定期锻炼”的衡量标准却并非如此。“朋友”支持与“家人”支持对身体活动四项指标的贡献均无显著差异；讨论：根据我们的研究结果，加强社会支持可能是干预措施的一个重要方面，旨在增加不同种族/民族背景的久坐妇女的身体活动。此外，这一人群中的“定期锻炼者”似乎不太依赖社会支持来维持他们的行为。1999爱思唯尔科学有限公司版权所有。
Background: Many American adults remain sedentary despite many known health benefits. Research on the determinants of physical activity have indicated that social support is one of the strongest correlates, but little is known about this relation in important subgroups of middle and older-aged women.Objective: The purpose of this study was to assess the association of physical activity-related social support on several measures of physical activity in a national sample of minority women. A unique aspect of these measures is the inclusion of vigorous household tasks and occupational physical activities.Methods. The US Women's Determinants Study was conducted in 1996-1987. The survey was a modified-random sampler telephone survey of 2912 Black, Hispanic, American Indian;Alaskan Native, and White women age 40 and older. A composite score of physical activity social support (PASS) was analyzed as the independent variable in logistic regression analyses. Four measures of physical activity levels served as the dependent variables. A separate analysis H as done to distinguish PASS from friends versus PASS from relatives. The potential confounding effect of race,'ethnicity. marital status, age, income and education were evaluated and adjusted in the models.Results. Hispanic women were more likely to have high PASS scores than the other racial/ethnic groups. Odds ratios indicate that subjects with high levels of PASS were significantly less likely to be sedentary than those with low support, even after adjusting for race/ethnicity. While there were significant associations among levels of social support and physical activity, this was not true for the measure of "regular exercise." There was no significant difference between the: contribution of "friend" support versus "family" support on all four measures on physical activity;Discussion: Based on our results, enhancing social support may be an important aspect of interventions aimed at increasing physical activity in a population of sedentary women of various racial/ethnic backgrounds. Also, "regular exercisers" in this population appear to be less reliant social support to maintain their behavior. (C) 1999 Elsevier Science Ltd. All rights reserved.
