To assess the association between health-related behaviors and quality of life among the elderly.
A population-based cross-sectional study was carried out including 1,958 elderly living in four areas in the state of São Paulo, southeastern Brazil, 2001/2002. Quality of life was assessed using the Medical Outcomes Study SF-36-Item Short Form Health Survey instrument. This instrument's eight subscales and two components were the dependent variables. Independent variables were physical activity, weekly frequency of alcohol consumption and smoking. Multiple linear regression models were used to control for the effect of gender, age, schooling, work, area of residence and number of chronic conditions.
Physical activity was positively associated with the eight SF-36 subscales. The stronger associations were found for role-physical (β=11.9), physical functioning (β=11.3) and physical component. Elderly individuals who consumed alcohol at least once a week showed a better quality of life than those did not consume alcohol. Compared to non-smokers, smokers had a poorer quality of life for the mental component (β=-2.4).
The study results showed that physical activity, moderate alcohol consumption and no smoking are positively associated with a better quality of life in the elderly.
评估健康相关行为与老年人生活质量之间的关系。
这是一项基于人群的横断面研究，共纳入了巴西东南部圣保罗州四个地区的 1958 名老年人（2001/2002 年）。使用健康调查简表 36 项条目（Medical Outcomes Study SF-36-Item Short Form Health Survey）评估生活质量。该量表的 8 个分量表和 2 个综合指标是因变量。独立变量为身体活动、每周饮酒频率和吸烟。采用多元线性回归模型控制性别、年龄、教育程度、工作、居住区域和慢性病数量的影响。
身体活动与 SF-36 的 8 个分量表呈正相关。角色身体机能（β=11.9）、身体机能（β=11.3）和身体成分与身体活动的相关性最强。每周至少饮酒一次的老年人比不饮酒的老年人生活质量更好。与不吸烟者相比，吸烟者的精神健康状况较差（β=-2.4）。
研究结果表明，身体活动、适量饮酒和不吸烟与老年人更好的生活质量相关。
