Description
Summary:To determine the physical activity level and factors influencing physical activity among pregnant urban Chinese women. This prospective cross-sectional study enrolled 1056 pregnant women (18-44 years of age) in Tianjin, China. Their socio-demographic characteristics were recorded, and the Pregnancy Physical Activity Questionnaire was used to assess their physical activity during pregnancy. The data were analyzed by multinomial logistic regression with adjustment for potential confounders. Median total energy expenditure of pregnant women in each of the three trimesters ranged from 18.50 to 21.90 metabolic equivalents of task (METs) h/day. They expended 1.76-1.85 MET h/day on moderate and vigorous activities and 0.11 MET h/day on exercise. Only 117 of the women (11.1%) met the international guideline for physical activity in pregnancy (≥150 min moderate intensity exercise per week). The most frequent reason given for not being more physically active was the fear of miscarriage. Higher education level (OR: 4.11, 95% CI: 1.59-10.62), habitual exercise before pregnancy (OR: 2.14, 95% CI: 1.39-3.28), and husbands who exercised regularly (OR: 2.21, 95% CI: 1.33-3.67) significantly increased the odds of meeting the guideline (p
