Research suggests that sedentary behavior (SB) and obesity are associated with disabilities in basic activities (BADL) and instrumental (IADL) activities of daily living. However, there is a lack of studies investigating this association in community-dwelling older adults. Thus, the aim of this study was to investigate the association between different SB typologies, isolated and in conjunction with obesity, and their associations with BADL and IADL disabilities in community-dwelling Brazilian older adults. This was a cross-sectional study using data from older adults (≥60 years) who participated in the Brazilian National Health Survey (2019). The exposures were obesity (BMI > 27 kg/m) and the amount of time spent daily on SB watching television (SB TV < 3 and ≥3 h/day) and engaging in leisure activities (SB leisure < 3 and ≥3 h/day), analyzed both separately and jointly. The outcomes were BADL and IADL disabilities. The main results showed that isolated SB TV ≥ 3 h/day (OR: 1.26; 95% CI: 1.14; 1.39) and SB TV ≥ 3 h/day combined with obesity (OR: 1.55; 95% CI: 1.37; 1.75) increased the odds of BADL and IADL disabilities. Obesity alone (OR: 1.21; 95% CI: 1.07; 1.36) increased only the odds of BADL disabilities. Moreover, SB leisure ≥ 3 h/day without obesity reduced the odds of IADL disabilities (OR: 0.56; 95% CI: 0.41; 0.76). Ideally, older adults should be encouraged to prevent obesity, reduce excessive periods spent in SB watching TV, and increase the daily periods spent in leisure activities, thus minimizing the likelihood of disabilities in functional activities.
研究表明，久坐行为（SB）和肥胖与日常生活中的基本活动（BADL）及工具性日常生活活动（IADL）能力障碍有关。然而，缺乏针对社区居住的老年人中这种关联的研究。因此，本研究的目的是调查不同类型的久坐行为（单独以及与肥胖相结合）与巴西社区居住老年人BADL和IADL能力障碍之间的关联。这是一项横断面研究，使用了参与巴西国家健康调查（2019年）的老年人（≥60岁）的数据。暴露因素为肥胖（BMI>27 kg/m）以及每天花在久坐行为上看电视的时间（SB TV<3小时/天和≥3小时/天）和从事休闲活动的时间（SB休闲<3小时/天和≥3小时/天），分别和联合进行分析。结果变量为BADL和IADL能力障碍。主要结果显示，单独的SB TV≥3小时/天（OR：1.26；95%CI：1.14；1.39）以及SB TV≥3小时/天与肥胖相结合（OR：1.55；95%CI：1.37；1.75）会增加BADL和IADL能力障碍的几率。仅肥胖（OR：1.21；95%CI：1.07；1.36）仅会增加BADL能力障碍的几率。此外，无肥胖的SB休闲≥3小时/天会降低IADL能力障碍的几率（OR：0.56；95%CI：0.41；0.76）。理想情况下，应鼓励老年人预防肥胖，减少花在久坐看电视上的过多时间，并增加每天花在休闲活动上的时间，从而将功能活动出现障碍的可能性降至最低。
