OBJECTIVE
First, to validate the LASA Physical Activity Questionnaire (LAPAQ) by a 7-day diary and a pedometer in older persons. Second, to assess the repeatability of the LAPAQ. Third, to compare the feasibility of these methods.
STUDY DESIGN AND SETTING
The study was performed in a subsample (n=439, aged 69-92 years) of the Longitudinal Aging Study Amsterdam (LASA). The LAPAQ was completed twice (1998/1999, 1999/2000). Respondents completed a 7-day activity diary and wore a pedometer for 7 days (1999/2000).
RESULTS
The LAPAQ was highly correlated with the 7-day diary (r=0.68, P<.001), and moderately with the pedometer (r=0.56, P<.001). The repeatability of the LAPAQ was reasonably good (weighted kappa: 0.65-0.75). The LAPAQ was completed in 5.7+/-2.7 min, and 0.5% of the respondents had missing values.
CONCLUSION
The LAPAQ appears to be a valid and reliable instrument for classifying physical activity in older people. The LAPAQ was easier to use than the 7-day diary and pedometer.
目的
第一，通过7天活动日记和计步器对老年人验证阿姆斯特丹纵向衰老研究（LASA）体力活动问卷（LAPAQ）。第二，评估LAPAQ的可重复性。第三，比较这些方法的可行性。
研究设计与设置
该研究在阿姆斯特丹纵向衰老研究（LASA）的一个子样本（n = 439，年龄69 - 92岁）中进行。LAPAQ完成了两次（1998/1999年，1999/2000年）。受访者完成了一份7天活动日记，并佩戴计步器7天（1999/2000年）。
结果
LAPAQ与7天活动日记高度相关（r = 0.68，P <.001），与计步器中度相关（r = 0.56，P <.001）。LAPAQ的可重复性相当好（加权kappa：0.65 - 0.75）。LAPAQ完成时间为5.7 ± 2.7分钟，0.5%的受访者有缺失值。
结论
LAPAQ似乎是一种用于对老年人身体活动进行分类的有效且可靠的工具。LAPAQ比7天活动日记和计步器更易于使用。
