客观的。建议没有医疗或产科并发症的孕妇进行体育锻炼。这项研究描述了美国孕妇客观测量的体力活动和久坐行为的患病率和相关性。方法。使用 2003 年至 2006 年国家健康和营养检查调查 (NHANES) 收集的横截面数据。 359 名 16 岁以上的孕妇佩戴加速度计 1 周。结果。女性平均每天参与 12.0 分钟（标准误差 (SE) 0.86）的中等活动和每天 0.3 分钟（SE 0.08）的剧烈活动。平均中度至剧烈体力活动因孕期而异：孕早期为 11.5 分钟/天，孕中期为 14.3 分钟/天，孕晚期为 7.6 分钟/天。平均而言，女性 57.1% 的监测时间用于久坐行为。在多变量调整模型中，与妊娠晚期相比，妊娠早期 (p = 0.02) 和中期 (p < 0.001) 的中度至剧烈体力活动较高。以及家庭收入较高的女性（p = 0.03）与家庭收入较低的女性相比。在多变量调整模型中，第二个三个月的平均每分钟计数高于第三个三个月 (p = 0.04)。结论。大多数孕妇在监测的一天中有一半以上的时间处于久坐行为，并且没有达到身体活动的建议。 (C) 2011 Elsevier Inc. 保留所有权利。
Objective. Physical activity is recommended for pregnant women without medical or obstetric complications. This study described the prevalence and correlates of objectively-measured physical activity and sedentary behavior among United States pregnant women.Methods. Using cross-sectional data collected front the 2003 to 2006 National Health and Nutrition Examination Survey (NHANES). 359 pregnant women >= 16 years wore an accelerometer for 1 week.Results. Women participated in a mean of 12.0 minutes/day (standard error (SE) 0.86) of moderate activity and 0.3 minutes/day (SE 0.08) of vigorous activity. Mean moderate to vigorous physical activity varied by trimester: 11.5 minutes/day in first trimester, 14.3 minutes/day in second trimester, and 7.6 minutes/day in third trimester. On average, women spent 57.1% of their monitored time in sedentary behaviors. In multivariable adjusted models, moderate to vigorous physical activity was higher in the first (p = 0.02) and second (p < 0.001) trimesters compared to the third trimester. and among women with higher household income (p = 0.03) compared to lower household income. In multivariable adjusted models, average counts/minute was higher in the second compared to the third trimester (p = 0.04).Conclusion. Most pregnant women spent more than half of the monitored day in sedentary behaviors and did not meet recommendations for physical activity. (C) 2011 Elsevier Inc. All rights reserved.
