To compare the Danish Physical Activity Questionnaire (DPAQ) estimating physical activity energy expenditure (PAEE) and physical activity level (PAL) and the pattern of physical activity (including health-related physical activity) with measurements from a validated position and motion instrument (ActiReg).
One hundred and thirty-eight healthy Danish volunteers aged 20-59 years participated. Participants filled in the DPAQ at the end of the day every day for seven consecutive days and carried the ActiReg on the same days as the DPAQ were filled in.
A small, but statistically significant difference was seen between the DPAQ and the ActiReg for PAEE (mean: -0.32 MJ x d(-1); 95% limits of agreement: ((-2.88)-2.24 MJ x d(-1)); P = 0.003) and PAL (-0.03; ((-0.37)-0.31); P = 0.02) for the whole group and for women (P < 0.008 for PAEE and PAL), but not for men. The correlation between methods was good for PAEE (r = 0.71, P < 0.001) and PAL (r = 0.64, P < 0.001). No difference was observed for time spent in moderate plus vigorous physical activity (MVPA) (P = 0.40). Time reported in MVPA with the DPAQ was positively correlated with time spent in MVPA measured by the ActiReg (p = 0.53, P < 0.001).
Although the volunteer sample may influence the representativeness of the results, the DPAQ provided a close estimate of PAEE, PAL (2-5% underestimation) and health-related physical activity (MVPA) in healthy adults at group level. The results indicate that the questionnaire can be used to rank individuals according to energy expenditure and level of total physical activity and to provide information on health-related physical activity.
比较丹麦体力活动问卷（DPAQ）对体力活动能量消耗（PAEE）、体力活动水平（PAL）及体力活动模式（包括与健康相关的体力活动）的评估结果，与经过验证的体位和运动仪器（ActiReg）的测量结果。
138名年龄在20 - 59岁的健康丹麦志愿者参与研究。参与者连续七天每天在当天结束时填写DPAQ，并在填写DPAQ的同一天佩戴ActiReg。
对于整个研究组以及女性，DPAQ与ActiReg在PAEE（均值：-0.32兆焦×天⁻¹；95%一致性界限：（-2.88至2.24兆焦×天⁻¹）；P = 0.003）和PAL（-0.03；（-0.37至0.31）；P = 0.02）方面存在微小但具有统计学意义的差异，但男性不存在此差异。两种方法在PAEE（r = 0.71，P < 0.001）和PAL（r = 0.64，P < 0.001）方面的相关性良好。在中等强度及剧烈体力活动（MVPA）时长方面未观察到差异（P = 0.40）。DPAQ报告的MVPA时间与ActiReg测量的MVPA时间呈正相关（p = 0.53，P < 0.001）。
尽管志愿者样本可能会影响结果的代表性，但在群体水平上，DPAQ对健康成年人的PAEE、PAL（低估2 - 5%）以及与健康相关的体力活动（MVPA）提供了较为接近的估计。结果表明，该问卷可用于根据能量消耗和总体力活动水平对个体进行排名，并提供与健康相关的体力活动信息。
