Study Objective

Adolescent pregnancy contributes to accelerated trajectories of adiposity and cardiometabolic diseases. Two potentially low-cost prevention strategies include promoting physical activity (PA) and limiting television (TV) viewing. Few studies have explored these behavior patterns in perinatal adolescents. This study sought to characterize PA and TV viewing in a socioeconomically disadvantaged perinatal adolescent population.

Design, Setting, Participants, and Interventions

A cross-sectional, retrospective, 10-item survey was used to explore behavior patterns in 79 predominantly Black (86%) postpartum adolescents. Main Outcome Measures: Outcomes included self-reported changes in PA from pre-pregnancy through pregnancy, and 7-day recall of PA and TV viewing in postpartum.

Results

The majority of adolescents (66%) reported being active on ≥3 days/week in pre-pregnancy; however, many reported low PA (≤2 days/wk) in their first (59%), second (66%), and third (54%) trimesters. Adolescents who reported being active on ≥5 days/wk in pre-pregnancy (19%) experienced first trimester PA decline, which subsequently plateaued. This group remained the most active throughout pregnancy. In postpartum, over half (54%) of all adolescents reported low PA and irrespective of PA, spent considerable time watching TV (median = 1680.0 minutes, inerquartile range = 2940).

Conclusion

Interventions promoting PA coupled with reducing TV viewing during pregnancy and in postpartum may benefit perinatal adolescents. The findings from this study suggest that PA history is a predictor of gestational PA, and low PA and high TV viewing in postpartum underscore the need for behavioral intervention. Conducting a brief assessment of PA history in early gestation may offer important insight.

在社会经济上处于不利地位的围产期青少年人群中，从孕前到产后身体活动和电视观看的变化

学习目标

青春期怀孕有助于加速肥胖和心脏代谢疾病的发展轨迹。两种潜在的低成本预防策略包括促进身体活动 (PA) 和限制看电视 (TV)。很少有研究探讨围产期青少年的这些行为模式。本研究试图描述在社会经济上处于不利地位的围产期青少年人群中的 PA 和电视收看情况。

设计、设置、参与者和干预

使用横断面、回顾性、10 项调查来探索 79 名以黑人为主 (86%) 的产后青少年的行为模式。主要结果测量：结果包括自我报告的从怀孕前到怀孕期间 PA 的变化，以及产后 7 天回忆 PA 和看电视的情况。

结果

大多数青少年 (66%) 报告在怀孕前每周至少有 3 天的活动；然而，许多人报告说在他们的第一个 (59%)、第二个 (66%) 和第三个 (54%) 三个月的 PA 较低（≤2 天/周）。报告在怀孕前每周活动≥5 天的青少年 (19%) 经历了孕早期 PA 下降，随后趋于稳定。该组在整个怀孕期间仍然是最活跃的。在产后，超过一半 (54%) 的青少年报告 PA 较低，并且无论 PA 是多少，都会花费大量时间看电视（中位数 = 1680.0 分钟，四分位数范围 = 2940）。

结论

促进体力活动并减少怀孕期间和产后看电视的干预措施可能有益于围产期青少年。这项研究的结果表明，PA 病史是妊娠期 PA 的预测因子，产后低 PA 和高电视观看率强调了行为干预的必要性。在妊娠早期对 PA 病史进行简要评估可能会提供重要的见解。
