ABSTRACT

To evaluate the validity of the Pregnancy Physical Activity (PA) Questionnaire (PPAQ) for long-term PA recall. Forty-eight women completed the PPAQ at 21, 32 weeks gestation, and 12 weeks postpartum. These women were emailed three separate PPAQs between two months and eight years after originally completing the questionnaires to recall their PA during those same time periods. Total number of metabolic (MET) minutes per week (MET-min*wk⁻¹) and percent time spent in light (%L), moderate (%M), and vigorous (%V) activity were compared between the original and long-term recall PPAQ values. Total MET-min*wk⁻¹ and %M were significantly underestimated by 3000–4000 MET-min*wk⁻¹ and 6%, respectively, and %L was overestimated by 4–6% (p < .05). Women reported spending little time in vigorous intensity activity (2–4%). Spearman correlations were lower for women who recalled PA ≥five years postpartum compared to women who recalled their PA <five years postpartum. However, these values were not significantly different (p > .05).

摘要

评估妊娠体育活动（PA）问卷（PPAQ）对于长期PA召回的有效性。48名妇女在妊娠21、32周和产后12周完成了PPAQ。在最初完成问卷调查后的两个月至八年内，通过电子邮件向这些妇女发送了三个单独的PPAQ，以在同一时期内召回她们的PA。比较了原始和长时间的每周代谢（MET）分钟总数（MET-min * wk ^-1）和光（％L），中度（％M）和剧烈（％V）活动所花费的时间百分比长期回忆PPAQ值。总MET-min * wk ^-1和％M分别被低估了3000–4000 MET-min * wk ^-1和6％，而％L被高估了4–6％（p<.05）。妇女报告称在剧烈运动中花的时间很少（2-4％）。召回PA≥5年的女性与召回PA小于5年的女性的Spearman相关性较低。但是，这些值没有显着差异（p > .05）。
