Many older people do not participate in organized exercise, and daily walking may be the most substantial contributor to physical activity. To investigate the association between daily walking behavior and self-reported health-related physical function, older community-dwelling volunteers wore activity-registering sensors for three days. Self-reported health-related physical functioning was measured using the SF36 10-item Physical Function subscale. Forty-six participants wore a sensor (mean age 77.6, SD 3.6, 61 % women). In a multiple regression model, steps per day (B=.005, p≤.001) and walks per day (B=-.174, p=.010) were associated with the SF36-PF subscale. The association between physical functioning and walks per day was negative: Those who took many walks per day may have been walking more indoors. Health professionals are likely justified in advising older people to incorporate walking into daily life for health purposes. The cross-sectional design does not allow for inferences about causality.
许多老年人不参加有组织的锻炼，日常步行可能是身体活动的最大贡献因素。为了研究日常步行行为与自我报告的健康相关身体功能之间的关联，居住在社区的老年志愿者佩戴活动记录传感器三天。使用SF36 10项身体功能分量表测量自我报告的健康相关身体功能。46名参与者佩戴了传感器（平均年龄77.6岁，标准差3.6，61%为女性）。在多元回归模型中，每天的步数（B=.005，p≤.001）和每天的步行次数（B=-.174，p=.010）与SF36-PF分量表相关。身体功能与每天步行次数之间的关联为负：每天步行次数多的人可能在室内走得更多。健康专业人员建议老年人为了健康目的将步行融入日常生活可能是合理的。横断面设计不允许对因果关系进行推断。
