Low-income women are at risk for excessive gestational weight gain. Inactive lifestyle and lack of regular moderate exercise may contribute to the risk of weight gain. This study was conducted to (1) determine the rate and characteristics of low-income pregnant women who exercised regularly and met the American College of Obstetricians and Gynecologists recommendation and (2) describe how these women spent time for other physical activities compared with those who did not exercise regularly. Medicaid-recipient or uninsured pregnant women (n = 816) were asked to complete a physical activity questionnaire at rural and urban county health departments located in North Carolina. Twenty percent of low-income women met the American College of Obstetricians and Gynecologists recommendation for moderate exercise (≥10 METs-h/wk [metabolic equivalent task-hours per week]). The women who met the recommendation spent 3 hours 45 minutes per week walking as exercise, whereas those who did not meet the recommendation spent 1 hour per week (P < .0001). Women who exercised regularly spent longer hours at work (4.25 vs. 1.75 hours per day; P = .019) and on household tasks (5.25 vs. 4.0 hours per day; P = .002) than women who did not exercise regularly. Time spent on domestic and occupation activities does not seem to prohibit low-income women from engaging in moderate exercise on a regular basis.
低收入女性有妊娠期体重过度增加的风险。久坐不动的生活方式和缺乏规律的适度运动可能会增加体重增加的风险。本研究旨在：（1）确定经常锻炼并符合美国妇产科医师学会建议的低收入孕妇的比例和特征；（2）描述这些女性与不经常锻炼的女性相比，在其他体育活动上的时间分配情况。研究要求北卡罗来纳州农村和城市县卫生部门的医疗补助受助者或未参保的孕妇（n = 816）填写一份体育活动问卷。20%的低收入女性达到了美国妇产科医师学会关于适度运动的建议（≥10梅脱-小时/周[每周代谢当量任务小时数]）。达到建议的女性每周花3小时45分钟步行锻炼，而未达到建议的女性每周花1小时（P <.0001）。经常锻炼的女性比不经常锻炼的女性在工作上花费的时间更长（每天4.25小时对1.75小时；P = 0.019），在家务上花费的时间也更长（每天5.25小时对4.0小时；P = 0.002）。花在家庭和职业活动上的时间似乎并不妨碍低收入女性定期进行适度运动。
