Low physical activity (PA) during the postpartum period is associated with weight retention. While patterns of PA have been examined in normal weight women during this period, little is known about PA among overweight and obese women. The aim of this cross-sectional study was to investigate PA and determine the proportion of women meeting recommendations for PA.
Women (n = 491), with a body mass index (BMI) ≥ 25 kg/m² were enrolled in a behavioral intervention. PA was assessed at six weeks postpartum using the Seven-Day PA Recall.
Women averaged 923 ± 100 minutes/day of sedentary/ light and 33 ± 56 minutes/day of combined moderate, hard, and very hard daily activity. Women with a BMI ≥ 40 kg/m² reported more time in sedentary/light activities and less hours of sleep than those with a lower BMI. Only 34% met national PA guidelines; this proportion was significantly lower among blacks (OR 0.5, CI 0.3-0.9).
These overweight and obese postpartum women reported a large percentage of time spent in sedentary/light activity, and a high proportion failed to meet minimal guidelines for PA. Promotion of PA in the postpartum period should focus on reducing sedentary behaviors and increasing moderate PA.
产后期间低体力活动（PA）与体重保留有关。虽然在此期间已经检查了正常体重女性的 PA 模式，但对于超重和肥胖女性的 PA 知之甚少。本横断面研究旨在调查 PA 并确定符合 PA 建议的女性比例。
BMI≥25kg/m²的女性（n=491）参加了一项行为干预。产后六周使用七天 PA 回忆评估 PA。
女性平均每天有 923±100 分钟的静坐/轻度活动和 33±56 分钟的中度、剧烈和非常剧烈的日常活动。BMI≥40kg/m²的女性比 BMI 较低的女性报告更多的静坐/轻度活动时间和更少的睡眠时间。只有 34%的人符合国家 PA 指南；黑人的这一比例明显较低（OR 0.5，CI 0.3-0.9）。
这些超重和肥胖的产后妇女报告了大量时间用于静坐/轻度活动，很大一部分人未能达到最低 PA 指南。产后期间应重点促进减少静坐行为和增加中等强度的 PA。
