In recent years, the number of pregnant women with obesity has increased exponentially; thus, it is important to evaluate and characterize the physical activity levels of this specific group. The aim of this study is to evaluate the reliability and validity of the Portuguese version of the Physical Activity and Pregnancy Questionnaire and Pregnancy Questionnaire in pregnant women with obesity and to classify physical activity using the Physical Activity and Pregnancy Questionnaire and accelerometry. An analytical observational study was carried out between May and August of 2019 at the University Hospital Center of São João, with a sample of 31 pregnant women with obesity (30.9 ± 4.6 years 36.5 ± 4.6 kg/m of BMI and 21.5 ± 9 gestational weeks). The physical activity of participants was evaluated using an accelerometer and Physical Activity and Pregnancy Questionnaire at two time points (the first visit at the moment of consultation and the second seven days after, with accelerometer retest), the interclass correlation coefficient was used to test reliability between the Physical Activity and Pregnancy Questionnaire filled out at visit1 and the Physical Activity and Pregnancy Questionnaire filled out at visit2, and Pearson's correlation was used to determine validity between the Physical Activity and Pregnancy Questionnaire and accelerometry. The interclass correlation coefficient values for total activity were 0.95, 0.97 for moderate and 0.58 for vigorous intensities. It ranged from 0.74 for sports/exercise to 0.96 for domestic activities. The Pearson's correlations showed that the Physical Activity and Pregnancy Questionnaire is moderately valid for moderate intensity (r = 0.435). A total of 67.7% of the pregnant women complied with international physical activity recommendations.
近年来，肥胖孕妇的数量呈指数级增长；因此，评估和描述这一特定群体的身体活动水平非常重要。本研究旨在评估肥胖孕妇的葡萄牙版《体力活动与妊娠问卷》和《妊娠问卷》的信度和效度，并使用《体力活动与妊娠问卷》和加速度计对体力活动进行分类。这是一项在 2019 年 5 月至 8 月间于圣若昂大学医院中心进行的分析性观察研究，样本为 31 名肥胖孕妇（30.9 ± 4.6 岁，36.5 ± 4.6kg/m 的 BMI，21.5 ± 9 孕周）。参与者的身体活动使用加速度计和《体力活动与妊娠问卷》在两个时间点进行评估（第一次就诊时和第二次就诊后七天，同时进行加速度计复测），使用组内相关系数来检验首次就诊时填写的《体力活动与妊娠问卷》与第二次就诊时填写的《体力活动与妊娠问卷》之间的可靠性，使用皮尔逊相关系数来确定《体力活动与妊娠问卷》与加速度计之间的效度。总活动的组内相关系数为 0.95，中等强度为 0.97，剧烈强度为 0.58。其范围从运动/锻炼的 0.74 到家务活动的 0.96。皮尔逊相关系数表明，《体力活动与妊娠问卷》对中等强度具有中度有效性（r = 0.435）。共有 67.7%的孕妇符合国际体力活动建议。
