For some women, pregnancy may increase the risk of future obesity with consequences for health and well-being. Psychosocial factors may be partly responsible for this. The aim of this study was to examine the association between psychosocial factors during pregnancy and postpartum weight retention (PPWR) at 6 and 18 months. A total of 37,127 women in The Danish National Birth Cohort (DNBC; 1996-2002) participated in four telephone interviews before and after delivery. They gave information about their experience of distress, depression and anxiety, social support, and psychosocial burdens during pregnancy. PPWR was defined as retention ≥ 5 kg at 6 and 18 months postpartum according to a woman's prepregnancy weight. The associations were examined by use of logistic regression and presented as odds radios with 95% confidence intervals. Women who were more likely to feel depressed/anxious or distressed during pregnancy had a higher risk of PPWR at 6 months (1.35 (1.27; 1.44) and 1.30 (1.22; 1.38)) and 18 months (1.34 (1.24; 1.45) and 1.32 (1.23; 1.42)). Likewise, women who felt burdened by their economy or working situation had a higher risk of PPWR as did women with the lowest incomes or less education. Women who reported a high level of distress or depression/anxiety both during pregnancy and in the first 6 months of motherhood had the highest risk of PPWR 18 months postpartum (1.54 (1.39; 1.71) and 1.49 (1.32; 1.69), respectively). Feeling distressed, depressed, or anxious during pregnancy was associated with higher PPWR as was personal and economical burdens. Adverse psychosocial characteristics may be a common determinant of weight retention after childbirth.
对于一些女性来说，怀孕可能会增加未来肥胖的风险，从而影响健康和幸福感。心理社会因素可能在一定程度上对此负有责任。本研究旨在探讨怀孕期间的心理社会因素与产后 6 个月和 18 个月时体重保留（PPWR）之间的关系。共有 37127 名妇女参加了丹麦全国出生队列研究（DNBC；1996-2002 年），她们在分娩前后参加了四次电话访谈。她们提供了有关怀孕期间困扰、抑郁和焦虑、社会支持以及心理社会负担的信息。PPWR 定义为产后 6 个月和 18 个月时体重保留≥5kg，根据女性的孕前体重。使用逻辑回归检查关联，并以 95%置信区间的比值比呈现。在怀孕期间更有可能感到抑郁/焦虑或困扰的女性，在产后 6 个月（1.35（1.27；1.44）和 1.30（1.22；1.38））和 18 个月（1.34（1.24；1.45）和 1.32（1.23；1.42））时发生 PPWR 的风险更高。同样，经济或工作状况负担过重的女性以及收入最低或教育程度最低的女性发生 PPWR 的风险也更高。报告在怀孕期间和产后 6 个月内都感到困扰或抑郁/焦虑的女性，在产后 18 个月时发生 PPWR 的风险最高（1.54（1.39；1.71）和 1.49（1.32；1.69））。怀孕期间感到困扰、抑郁或焦虑与更高的 PPWR 相关，个人和经济负担也是如此。不良的心理社会特征可能是产后体重保留的共同决定因素。
