To evaluate the nutritional status (NS) and its association with physical performance tests (PPT) of elderly in the city of São Paulo, Brazil.
Design--Cross-sectional epidemiological study, in a population on a household basis as part of a multicenter study (the SABE Survey), coordinated by the Pan-American Health Organization. Setting-- From January/2000 to March/2001, the SABE survey comprised 2143 elderly (>or=60 yrs old), of both genders, selected by probabilistic sampling. Of these, 1894 (88.4%) took part in this study. The elderly were separated by gender and age group (60-69, 70-79 and>or=80 yrs old) for the tests and the NS was evaluated according to the Body Mass Index (BMI): underweight (BMI<or=23 kg/m2) and obese (BMI>or=28 kg/m2). The PPTs included timed, repeated "chair stand" (CS), timed "pick up a pen" (PP) and standing balance (SB). The associations (CS and PP) were verified by the Cox Regression analysis and (SB) by the chi square test.
There were statistically significant associations between PP and SB and obese women.
Results showed association between nutritional status and functional capacity for women and obesity was the nutritional condition associated with the worst performance in the tests. Gender and age group should be considered in the association between nutritional status and physical performance.
评估巴西圣保罗市老年人的营养状况（NS）及其与体能测试（PPT）的关联。
设计——横断面流行病学研究，以家庭为基础对人群进行研究，作为泛美卫生组织协调的多中心研究（SABE调查）的一部分。背景——2000年1月至2001年3月，SABE调查通过概率抽样选取了2143名60岁及以上的老年人，男女皆有。其中，1894人（88.4%）参与了本研究。根据性别和年龄组（60 - 69岁、70 - 79岁和80岁及以上）对老年人进行分组测试，并根据体重指数（BMI）评估营养状况：体重过轻（BMI≤23kg/m²）和肥胖（BMI≥28kg/m²）。体能测试包括定时重复的“椅子站立”（CS）、定时“拿起一支笔”（PP）和站立平衡（SB）。通过Cox回归分析验证（CS和PP）的关联，通过卡方检验验证（SB）的关联。
PP和SB与肥胖女性之间存在统计学上的显著关联。
结果显示营养状况与女性功能能力之间存在关联，肥胖是与测试中最差表现相关的营养状况。在营养状况与体能表现的关联中应考虑性别和年龄组。
