Postpartum weight retention is a significant contributor to obesity in women, adverse perinatal events in subsequent pregnancies, and chronic disease risk. Health literacy is known to impact health behaviors. The study aimed to identify the health literacy domains utilized in postpartum weight management interventions and to determine their impact on weight, diet and physical activity in postpartum women.
We searched MEDLINE, CINAHL, EMBASE, PSYCINFO, and EBM databases. We included random control trials of lifestyle intervention in postpartum women (within two years post-delivery) published up to 3 May 2019. Subgroup analyses were performed to determine the effect of health literacy domains on outcomes.
Out of 5000 studies, 33 studies ( = 3905) were included in the systematic review and meta-analysis. The health literacy domain self-care (skills and knowledge) was associated with a significant reduction in body weight (mean difference (MD) -2.46 kg; 95% confidence interval (CI) from -3.65 to -1.27) and increase in physical activity (standardized mean difference (SMD) 0.61; 95% CI 0.20 to 1.02). No other health literacy domain was associated with significant outcomes in weight, energy intake, or physical activity.
Health literacy skills such as knowledge of self-care are effective in improving weight and in increasing physical activity in postpartum women. The efficacy of other health domains was not supported.
产后体重滞留是导致女性肥胖、后续妊娠不良围产期事件及慢性病风险的重要因素。已知健康素养会影响健康行为。本研究旨在确定产后体重管理干预措施中所使用的健康素养领域，并确定其对产后女性体重、饮食和身体活动的影响。
我们检索了MEDLINE、CINAHL、EMBASE、PSYCINFO和循证医学数据库。纳入截至2019年5月3日发表的关于产后女性（分娩后两年内）生活方式干预的随机对照试验。进行亚组分析以确定健康素养领域对结果的影响。
在5000项研究中，33项研究（n = 3905）被纳入系统评价和荟萃分析。健康素养领域的自我护理（技能和知识）与体重显著降低（平均差（MD）-2.46 kg；95%置信区间（CI）为-3.65至-1.27）及身体活动增加（标准化平均差（SMD）0.61；95%CI为0.20至1.02）相关。没有其他健康素养领域与体重、能量摄入或身体活动的显著结果相关。
自我护理知识等健康素养技能在改善产后女性体重和增加身体活动方面有效。其他健康领域的功效未得到证实。
