The study aimed to describe the prevalence of meeting moderate-to-vigorous-intensity physical activity (MVPA), muscle-strengthening (MS) activities, and television (TV) viewing guidelines, and their association with sociodemographic factors. Data from older adults aged 65 or above were sampled by age and sex to the population aged 65+ years for each area in Taiwan and collected through telephone interviews. The prevalence of meeting MVPA and MS activities, MVPA and MS activities guidelines, and excessive TV viewing were calculated. We also investigated their associations with sociodemographic variables using logistic regression analyses. A total of 1068 older adults (response rate: 32.5%) participated in the present study. 79.4% met the MVPA guidelines (150 min weekly), 25.3% met the MS guidelines (twice a week), 22.4% met both MVPA and MS guidelines, and 53.1% engaged in excessive TV viewing (more than or equal to two hours per day). Overall, in old age, low educational level was associated with lower odds of meeting MVPA and MS activities, and both the MVPA and MS activity guidelines; while living alone and having no full-time job had higher odds of excessive TV viewing. A large number of older adults do not meet the MS recommendations, but are engaged in excessive TV viewing. Our findings may be important for public health interventions to promote MS and avoid excessive TV viewing, especially for at-risk subgroups.
本研究旨在描述达到中等至剧烈强度身体活动（MVPA）、肌肉强化（MS）活动的流行率，以及电视（TV）观看指南的流行率，并探讨其与社会人口因素的关系。通过按年龄和性别对台湾各地区 65 岁及以上的老年人进行抽样，并通过电话访谈收集数据。计算出达到 MVPA 和 MS 活动、MVPA 和 MS 活动指南以及过度观看电视的流行率。我们还使用逻辑回归分析调查了它们与社会人口变量的关联。共有 1068 名老年人（应答率：32.5%）参加了本研究。79.4%的人达到了 MVPA 指南（每周 150 分钟），25.3%的人达到了 MS 指南（每周两次），22.4%的人同时达到了 MVPA 和 MS 指南，53.1%的人过度观看电视（每天超过或等于两小时）。总的来说，在老年时，低教育水平与较低的达到 MVPA 和 MS 活动以及 MVPA 和 MS 活动指南的几率相关；而独居和没有全职工作则与过度观看电视的几率增加相关。大量老年人不符合 MS 建议，但过度观看电视。我们的研究结果对于促进 MS 和避免过度观看电视的公共卫生干预措施可能很重要，特别是对于处于风险中的亚组。
