Growing evidence of lower physical activity (PA), higher sedentary behavior, and prevalence of overweight and obesity in African countries calls for more research on PA behavior and its various correlates in this context. This study examined the proportion of adults meeting World Health Organization PA guidelines from 3 urban regions of Botswana, as well as the relationship among sociodemographic factors, body image, and participation in moderate to vigorous PA.
Using a 2-stage stratified cluster sampling approach, cross-sectional data were collected from 699 participants (females = 66%; M = 32.60 y; SD = 11.96).
Overall, 45.8% of participants met World Health Organization PA guidelines. Censored regression analyses indicated that females (B = -221.573, P < .001), and individuals from middle- (B = -331.913, P < .001), and high-income (B = -165.185, P = .036) households spent significantly less minutes in moderate to vigorous PA per week. Evaluative (B = -333.200, P < .001) and affective (B = -158.753, P = .038) components of body image were associated with significantly less minutes spent in moderate to vigorous PA per week.
A systematic approach to PA promotion that targets females, middle- to high-income groups, and individuals experiencing body image concerns is needed.
越来越多的证据表明，非洲国家的体力活动（PA）水平较低，久坐行为较多，超重和肥胖的患病率较高，因此需要在这一背景下对 PA 行为及其各种相关因素进行更多的研究。本研究调查了来自博茨瓦纳 3 个城市地区的成年人符合世界卫生组织 PA 指南的比例，以及社会人口因素、身体形象和参与中等到剧烈 PA 之间的关系。
采用两阶段分层聚类抽样方法，从 699 名参与者（女性=66%；M=32.60 岁；SD=11.96）中收集了横断面数据。
总体而言，有 45.8%的参与者符合世界卫生组织 PA 指南。有条件回归分析表明，女性（B=-221.573，P<.001），以及来自中等（B=-331.913，P<.001）和高收入（B=-165.185，P=.036）家庭的个体每周中到剧烈 PA 的时间明显较少。身体形象的评价（B=-333.200，P<.001）和情感（B=-158.753，P=.038）成分与每周中到剧烈 PA 的时间显著减少有关。
需要采取系统的 PA 促进方法，针对女性、中高收入群体和身体形象有问题的个体。
