The aims of this study were to describe the prevalence, trends, and correlates of physical activity among a national sample of pregnant women.
Using data collected from the 1999-2006 National Health and Nutrition Examination Survey, physical activity and sedentary behaviors were collected during interviews with 1280 pregnant women >/=16 years. Estimates were weighted to reflect the United States population.
Overall 22.8% reported any transportation activity (i.e., to/from work/school), 54.3% reported any moderate to vigorous household activity, and 56.6% reported any moderate to vigorous leisure activity, all in the past month. Participation in any transportation and moderate to vigorous leisure activity was stable over time, while participation in any moderate to vigorous household activities and moderate leisure activities increased from 1999-2002 to 2003-06. Moderate to vigorous leisure activity was significantly higher among those in first trimester compared to third trimester, among non-Hispanic white participants compared to women from other race/ethnic groups, and among those with health insurance compared to those without. From 2003 to 2006, 15.3% of pregnant women reported watching 5 h or more of television or videos per day.
These data could be used to monitor trends and set national goals for physical activity among pregnant women.
本研究旨在描述全国孕妇样本中身体活动的流行率、趋势和相关因素。
使用 1999-2006 年全国健康与营养调查收集的数据，对 1280 名年龄≥16 岁的孕妇进行访谈，收集身体活动和久坐行为数据。估计数经过加权处理，以反映美国人口情况。
总体而言，22.8%的孕妇报告有任何交通活动（即上下班/上下学），54.3%报告有任何适度至剧烈强度的家务活动，56.6%报告有任何适度至剧烈强度的休闲活动，均在过去一个月内。参与任何交通和适度至剧烈强度休闲活动的比例随时间保持稳定，而参与任何适度至剧烈强度家务活动和适度休闲活动的比例从 1999-2002 年增加到 2003-06 年。与第三孕期相比，第一孕期孕妇进行适度至剧烈强度休闲活动的比例显著更高；与其他种族/族裔群体的女性相比，非西班牙裔白人参与者进行适度至剧烈强度休闲活动的比例更高；与没有医疗保险的孕妇相比，有医疗保险的孕妇进行适度至剧烈强度休闲活动的比例更高。从 2003 年到 2006 年，15.3%的孕妇报告每天看 5 小时或以上的电视或视频。
这些数据可用于监测孕妇身体活动的趋势并为其设定国家目标。
