This study examined sedentary behaviors among older adults and explored associations with social context and health measures using cross-sectional data from the National Health and Aging Trends Study (N = 1,687). Multivariate models were estimated to explore associations of time in six sedentary behaviors (i.e., television watching, sitting and talking, hobbies, computer use, driving, and resting) with sociodemographic characteristics and level of social engagement and with health status. Results indicated substantial variability in sedentary behaviors, with television watching being the most frequent and resting the least frequent activities. Sedentary behaviors varied by sociodemographic characteristics, including age, race/ethnicity, and education, as well as by level of social engagement. Television watching and resting, but not other behaviors, were associated with poorer health. These findings help to unpack the role of social context in sedentary behaviors and could inform public health interventions aimed at reducing time spent in behaviors that are adversely associated with health.
本研究利用来自美国国家健康与老龄化趋势研究的横断面数据(N = 1687),调查了老年人的久坐行为,并探讨了其与社会环境和健康指标之间的关联。我们估计了多变量模型,以探究六种久坐行为(即看电视、坐着交谈、业余爱好、使用电脑、开车和休息)的时长与社会人口学特征、社会参与水平以及健康状况之间的关联。结果表明,久坐行为存在很大差异,看电视是最常见的活动,而休息是最不常见的活动。久坐行为因社会人口学特征(包括年龄、种族/族裔和教育程度)以及社会参与水平而异。看电视和休息与较差的健康状况相关,而其他行为则不然。这些发现有助于剖析社会环境在久坐行为中的作用,并可为旨在减少与健康状况负相关行为时长的公共卫生干预措施提供参考。
