It is generally recommended that healthy, pregnant women should engage in moderate exercise on most days of the week. However, there is scant knowledge about the overall physical activity and exercise levels among pregnant women.
To assess the total physical activity level of pregnant women, and to investigate the association between weight gain, physical activity and exercise during pregnancy.
Pregnant women (n=467) answered a questionnaire on total physical activity level in gestation week 36.
Some 55% of the participants reported working in a sitting position. Most women drove (52.9%) or used public transport (31.7%) to work. A total of 39% reported sedentary activities of>or=4 h (watching television and reading) daily; 19% were defined as non-exercisers before pregnancy, 30% in the first trimester, 36% in the second trimester and 53% in the third trimester. Fifty women (10.6%) continued to exercise>or=4 times/week in the third trimester. Mean weight gain was 13.8 kg (SD: 5.2). Of the normal pregestational weight women (pre-BMI: <26) and overweight women (pre-BMI: >or=26), 32 and 51% had exceeded weight gain above accepted recommendations, respectively. Women who exercised regularly had significantly lower weight gain than inactive women in the third trimester only.
Pregnant women have a low total physical activity level, and a high percentage of women exceed the recommended weight gain during pregnancy.
一般建议健康的孕妇应在一周中的大多数日子进行适度运动。然而，对于孕妇的总体身体活动和运动水平了解甚少。
评估孕妇的总体身体活动水平，并调查孕期体重增加、身体活动与运动之间的关联。
467名孕妇回答了关于妊娠36周时总体身体活动水平的问卷。
约55%的参与者报告工作时需久坐。大多数女性开车（52.9%）或乘坐公共交通工具（31.7%）上班。共有39%的人报告每天有≥4小时的久坐活动（看电视和阅读）；19%的人在怀孕前被定义为不运动者，孕早期为30%，孕中期为36%，孕晚期为53%。50名女性（10.6%）在孕晚期继续每周运动≥4次。平均体重增加13.8千克（标准差：5.2）。孕前体重正常的女性（孕前BMI：<26）和超重女性（孕前BMI：≥26）中，分别有32%和51%的人孕期体重增加超过了推荐范围。仅在孕晚期，经常运动的女性体重增加明显低于不运动的女性。
孕妇的总体身体活动水平较低，且有很高比例的女性孕期体重增加超过了推荐范围。
