The present study examined activity behavior, nutritional status and perceived health in relation to the number of chronic diseases (ChrD) in a representative sample of Brazilians aged ≥60 years.
A cross-sectional, population-based study was carried out in a midsize Brazilian city to evaluate different health risk factors. Using a stratified random sampling procedure to select a representative sample of adults, this study interviewed 1572 individuals face-to-face. Our analytical sample focused on those aged ≥60 years (n = 355). Statistical procedures were carried out using spss software, with the significance level set as P < 0.05.
Older adults diagnosed with ≥2 ChrD were significantly less active during leisure time physical activity (P = 0.03), presented with significant higher body mass index values (P < 0.001) and were approximately fivefold (1.69-17.93) more likely to perceive their health as poor compared with those with zero ChrD. The group with ≥2 ChrD reported a similar amount of sitting time compared with older adults with zero or one ChrD (P > 0.05).
Having multiple ChrD has a negative impact on older adults' leisure time physical activity, body mass index and the perception of health. The findings of the present study underscore the need for more infusive approaches tackling ChrD in Brazil focusing on healthy lifestyle behaviors, such as physical activity.

本研究旨在调查与慢性疾病（ChrD）数量相关的活动行为、营养状况和健康感知在巴西代表性≥60 岁人群中的情况。
本研究在巴西一个中等城市进行了一项横断面、基于人群的研究，以评估不同的健康风险因素。采用分层随机抽样程序选择成人的代表性样本，本研究面对面采访了 1572 人。我们的分析样本集中在≥60 岁的人群（n=355）。使用 spss 软件进行统计分析，显著性水平设置为 P<0.05。
被诊断患有≥2 种 ChrD 的老年人在休闲时间体力活动中明显不活跃（P=0.03），体重指数值显著升高（P<0.001），并且与无 ChrD 或仅有一种 ChrD 的老年人相比，他们大约有五倍（1.69-17.93）更有可能认为自己的健康状况较差。与无 ChrD 或仅有 1 种 ChrD 的老年人相比，患有≥2 种 ChrD 的老年人报告的久坐时间相似（P>0.05）。
患有多种 ChrD 会对老年人的休闲时间体力活动、体重指数和健康感知产生负面影响。本研究的结果强调了在巴西需要采取更全面的方法来处理 ChrD，重点是健康的生活方式行为，如体力活动。老年医学与老年病学国际 2017；17：2376-2382。
