A physical activity questionnaire was developed with the aim to estimate usual individual daily energy expenditure. The questionnaire focused on the number of hours usually spent on various activities. In a pilot study it was tested for repeatability and validity in a population of 126 Dutch adults (64 men, 62 women).
For assessment of repeatability the questionnaire was administered three times during the course of 1 year. A four-times-repeated 3-day activity diary was used as a reference instrument to evaluate validity.
Differences in mean energy expenditure among repeated administrations of the questionnaire were small and not significant. Spearman's test-retest correlation coefficients for total energy expenditure for men were 0.76 [95% confidence interval (CI) 0.63-0.85] and 0.70 (95% CI 0.54-0.81) at 5 and 11 months, respectively, and for women were 0.58 (95% CI 0.36-0.74) and 0.71 (95% CI 0.54-0.82). There was a significant trend showing increasing mean diary energy expenditure for successive tertiles of questionnaire energy expenditure. The correlation between the questionnaire and the diary was 0.66 (95% CI 0.49-0.78) for men and 0.43 (95% CI 0.18-0.63) for women.
It was concluded that this questionnaire is a useful tool for estimating energy expenditure in epidemiological studies.
开发了一份体力活动问卷，旨在估算个体日常的能量消耗。该问卷聚焦于通常花在各种活动上的小时数。在一项试点研究中，对126名荷兰成年人（64名男性，62名女性）进行了重复性和有效性测试。
为评估重复性，在1年时间内对问卷进行了3次发放。使用一份重复4次的3天活动日记作为评估有效性的参考工具。
问卷重复发放期间，平均能量消耗的差异较小且无统计学意义。男性总能量消耗的Spearman重测相关系数在5个月和11个月时分别为0.76[95%置信区间（CI）0.63 - 0.85]和0.70（95%CI 0.54 - 0.81），女性分别为0.58（95%CI 0.36 - 0.74）和0.71（95%CI 0.54 - 0.82）。对于问卷能量消耗的连续三分位数，活动日记的平均能量消耗呈现出显著的上升趋势。问卷与活动日记的相关性，男性为0.66（95%CI 0.49 - 0.78），女性为0.43（95%CI 0.18 - 0.63）。
得出结论，该问卷是流行病学研究中估算能量消耗的有用工具。
