OBJECTIVES
to evaluate the relationship between leisure-time physical activity and functional capacity change among aged people.
METHODS
we analyzed data of an aged cohort looking for determinants of functional capacity at follow-up. Baseline data were collected between 2007 and 2008 - average follow-up of 3,5 years. A full multivariate linear regression model was built to evaluate functional capacity at the end of the follow-up, controlling for functional capacity at baseline, sociodemographic, health and behavioral characteristics and amount of leisure-time physical activity in the period.
RESULTS
final model showed functional capacity independently correlated with age (p<0.001), body mass (p=0.013) and the number of activities of daily living compromised at baseline (p<0.001). Functional capacity improved with increased physical activity but loss statistical significance after adjustments (p=0.384).
CONCLUSIONS
functional capacity decreases with increased age, increased loss of functional capacity at baseline and increased body mass. Albeit a non-significant association, leisure-time physical activity appears as an important modifiable factor.
目的
评估老年人闲暇时体力活动与功能能力变化之间的关系。
方法
我们分析了一个老年人队列的资料，以寻找随访时功能能力的决定因素。基线数据收集于 2007 年至 2008 年之间-平均随访 3.5 年。建立了一个完整的多变量线性回归模型，以评估随访结束时的功能能力，控制基线时的功能能力、社会人口统计学、健康和行为特征以及闲暇时体力活动的数量。
结果
最终模型显示，功能能力与年龄（p<0.001）、体重（p=0.013）和基线时日常生活活动受损的数量（p<0.001）独立相关。体力活动增加与功能能力改善相关，但调整后失去统计学意义（p=0.384）。
结论
功能能力随年龄增长、基线时功能能力丧失增加和体重增加而下降。尽管关联性不显著，但闲暇时体力活动似乎是一个重要的可改变因素。
