This study examined the associations of Dietary Inflammatory Index (DII) with weight outcomes within 1 year post partum.
This analysis included women who participated in a cohort study in South China (n = 468). The assessments included maternal height, weight, and dietary intake. The latter variable was based on three consecutive 24-hour food records collected at 2 weeks and 1 year after childbirth and was used to calculate the energy-adjusted DII (EDII) scores during and after puerperium, respectively. A general linear regression was performed to examine the relationships between the EDII scores and postpartum weight outcomes after adjusting for confounders.
In an analysis adjusted for confounders, the EDII during puerperium was positively associated with the weight change from 3 to 42 days (β: 0.42, 95% CI: 0.11-0.70). The EDII after puerperium was positively correlated with the weight changes from 42 days to 1 year (β: 0.52, 95% CI: 0.02-1.02) and from 3 days to 1 year (β: 0.63, 95% CI: 0.13-1.14), as well as with the postpartum weight retention at 1 year after childbirth (β: 0.75, 95% CI: 0.29-1.22).
The results indicate that a diet with a high EDII score might minimize postpartum weight loss and promote higher postpartum weight retention.
本研究旨在探讨饮食炎症指数（DII）与产后 1 年内体重变化的关系。
本分析纳入了参加中国南方队列研究的女性（n=468）。评估包括母亲的身高、体重和饮食摄入。后者基于产后 2 周和 1 年时连续 3 天的 24 小时饮食记录，用于分别计算产褥期和产褥期后能量调整的 DII（EDII）评分。采用一般线性回归分析调整混杂因素后 EDII 评分与产后体重变化之间的关系。
在调整混杂因素的分析中，产褥期 EDII 与产后 3 至 42 天体重变化呈正相关（β：0.42，95%CI：0.11-0.70）。产褥期后 EDII 与产后 42 天至 1 年（β：0.52，95%CI：0.02-1.02）和产后 3 天至 1 年（β：0.63，95%CI：0.13-1.14）的体重变化以及产后 1 年体重保留（β：0.75，95%CI：0.29-1.22）呈正相关。
结果表明，高 EDII 评分的饮食可能会最大限度地减少产后体重减轻并促进更高的产后体重保留。
