The benefits of taking up physical activity are well established and social support has been identified as one of the main determinants of this behavior.
To investigate the association between social support and weekly frequency of physical activity in adults working at a public university in the state of Rio de Janeiro, Brazil.
This is a cross-sectional population study with a convenience sample of 189 contract workers of both sexes, aged from 21 to 72 years (39.00 ± 11.43). The instruments employed were the short version of the International Physical Activity Questionnaire and the Social Support for Physical Activities Scale. Fisher's exact test was used to estimate the distribution of physical activity frequency. Poisson regression was used for association analyses. The significance level was set at 5%.
A significant association was detected between social support and weekly physical activity frequency (p < 0.05). Social support for physical activity of moderate or vigorous intensity was associated with both weekly frequency of walking (odds ratio [OR]: 1.32; 95% confidence interval [95%CI]: 1.11-1.58) and weekly frequency of vigorous physical activity (OR: 1.34; 95%CI: 1.08-1.67). Additionally, people who reported receiving social support for walking were more likely to have increased weekly frequency of walking (OR: 1.22; 95%CI: 1.00-1.49).
Social support for physical activity from relatives and friends is associated with weekly physical activity frequency. Notwithstanding, this association was stronger for weekly frequency of vigorous intensity physical activity.
进行体育活动的益处已得到充分证实，社会支持被认为是这种行为的主要决定因素之一。
调查巴西里约热内卢州一所公立大学在职成年人的社会支持与每周体育活动频率之间的关联。
这是一项横断面人群研究，采用便利抽样法，选取了189名年龄在21至72岁（39.00±11.43）的男女合同制工人。所使用的工具为国际体力活动问卷简版和体育活动社会支持量表。采用费舍尔精确检验来估计体育活动频率的分布。使用泊松回归进行关联分析。显著性水平设定为5%。
在社会支持与每周体育活动频率之间检测到显著关联（p<0.05）。对中等强度或剧烈强度体育活动的社会支持与每周步行频率（优势比[OR]：1.32；95%置信区间[95%CI]：1.11 - 1.58）以及每周剧烈体育活动频率（OR：1.34；95%CI：1.08 - 1.67）均相关。此外，报告在步行方面获得社会支持的人每周步行频率增加的可能性更大（OR：1.22；95%CI：1.00 - 1.49）。
来自亲属和朋友的体育活动社会支持与每周体育活动频率相关。尽管如此，这种关联在每周剧烈强度体育活动频率方面更强。
