We determined the prevalence and correlates of insufficient physical activity and high sedentary behavior among a nationally representative sample of 2,240 older adults (≥60 years) in Singapore. The Global Physical Activity Questionnaire, administered through face-to-face interviews, assessed physical activity and sedentary behavior. Logistic regression identified the correlates of insufficient physical activity (<600 metabolic equivalent of task minutes/week) and high sedentary behavior (>7 hr/day). The prevalence of insufficient physical activity and high sedentary behavior was 33.7% and 17.3%, respectively. Those older, females, Malays, residing in smaller housing, living with child but no spouse, with functional limitations and sensory impairments (vision/hearing) were more likely to have insufficient physical activity whereas those with tertiary education had lower odds. High sedentary behavior was more likely among those older, with secondary education, preobesity/obesity, and with functional limitations. While policies should encourage all older adults to be physically active, at-risk subgroups identified in our study merit greater attention.

我们确定了新加坡 2,240 名老年人（≥60 岁）的全国代表性样本中身体活动不足和久坐行为的流行率和相关性。全球身体活动问卷通过面对面访谈进行，评估了身体活动和久坐行为。逻辑回归确定了身体活动不足（<600 代谢当量的任务分钟/周）和久坐行为（>7 小时/天）之间的相关性。身体活动不足和久坐行为的患病率分别为 33.7% 和 17.3%。那些年长的女性马来人，居住在较小的房屋，与孩子同住但没有配偶，有功能限制和感觉障碍（视觉/听觉）的人更有可能身体活动不足，而那些受过高等教育的人有较低的几率。久坐不动的行为更可能发生在年龄较大、受过中等教育、肥胖前/肥胖和功能受限的人群中。虽然政策应鼓励所有老年人进行体育锻炼，但我们研究中确定的高危亚群值得更多关注。
