UNASSIGNED: This secondary data analysis included the standard of care group (n = 439) from the U.S.-based Lifestyle Interventions For Expectant Moms (LIFE-Moms) consortium, including persons with overweight and obesity. Wrist-worn accelerometry was used to measure movement behaviors early (9-15 weeks) and late (35-36 weeks) pregnancy, and ∼ 1-year postpartum. Sleep and moderate-to-vigorous PA (MVPA) were compared to adult and pregnancy-specific guidelines, respectively. SB was classified into quartiles. PA and SB context were quantified using questionnaires. Mixed models were used to examine changes in behaviors and guidelines and identify correlates.
UNASSIGNED: Participants were 31.3 ± 3.5 years, 53.5 % were Black or Hispanic, and 45.1 % had overweight. Sleep duration decreased across time, but participants consistently met the guideline (range: 85.0-93.6 %). SB increased during pregnancy and decreased postpartum, while light PA and MVPA followed the inverse pattern. Participants met slightly fewer guidelines late pregnancy (1.2 ± 0.7 guidelines) but more postpartum (1.7 ± 0.8 guidelines) than early pregnancy (1.4 ± 0.8 guidelines). Black or Hispanic race/ethnicity, higher pregravid body mass index, and non-day work-shift (e.g., night-shift) were identified correlates of lower guideline adherence and varying PA and SB context.
UNASSIGNED: Perinatal interventions should consider strategies to prevent SB increase and sustain MVPA to promote guideline adherence.
■此次要数据分析包括来自美国的准妈妈生活方式干预(LIFE-Moms)联盟的标准护理组(n=439),包括超重和肥胖的人。使用腕部加速度测量法测量妊娠早期(9-15周)和晚期(35-36周)的运动行为,产后1年。将睡眠和中度至重度PA(MVPA)与成人和妊娠特定指南进行了比较。分别。SB被分类为四分位数。使用问卷对PA和SB背景进行量化。混合模型用于检查行为和指南的变化并确定相关性。
■参与者为31.3±3.5岁,53.5%是黑人或西班牙裔,和45.1%的人超重。睡眠持续时间随时间减少,但参与者始终符合指南(范围:85.0-93.6%)。SB在怀孕期间增加,产后减少,光PA和MVPA遵循相反的模式。参与者在妊娠晚期(1.2±0.7指南)中遇到的指南略少,但产后(1.7±0.8指南)比早孕(1.4±0.8指南)多。黑人或西班牙裔种族/种族,较高的孕前体重指数,和非日间工作轮班(例如,夜班)确定了较低的指南依从性和不同的PA和SB背景的相关性。
■围产期干预措施应考虑预防SB升高和维持MVPA的策略,以提高指南的依从性。
