Objective To investigate the dietary intakes and weight retention status of postpartum women in Wuhan and explore the influence of dietary intervention on postpartum weight retention,providing scientific basis for rational dietary guid-ance to prevent excessive postpartum weight retention.Methods A total of 184 postpartum women at 42 days postpartum were included from September 2022 to April 2024 as participants and randomly divided into the control group(91 cases)and the inter-vention group(93 cases).Basic information on sociodemographic and lifestyle of the subjects were investigated,and body mass change was measured.The dietary intake was evaluated by the Da Ying Jia Intelligent Dietary Management System 2.0,and the overall dietary quality was evaluated by the alternate healthy eating index(AHEI).Individualized nutritional meal planning was provided to the intervention group,and follow-up was conducted to evaluate weight retention and the effect of dietary interven-tion at 3-month and 6-month postpartum.Results Compared with the body weight at inclusion,the average weight loss in the intervention group at 3-month postpartum was(0.95±2.38)kg,while the average weight loss in the control group was(0.14±1.44)kg.The average weight loss in the intervention group at 6-month postpartum was(2.29±3.64)kg,while the average weight loss in the control group was(0.04±2.99)kg.The weight retention rate in the intervention group(21.0％)was signifi-cantly lower than that in the control group(36.8％)(P＜0.05).Dietary analysis showed that at 3-month postpartum,the intake of egg and aquatic products in the intervention group was significantly higher than that in the control group(P＜0.05),and the AHEI score of white meat/red meat in the intervention group was significantly higher than that in the control group(P＜0.05).The intervention group would pay more attention to the intake of white meat when choosing meat.The intake of vegeta-bles and fungi/algae in both groups decreased at 6-month postpartum,but the decrease in the vegetables and fungi/algae score in the intervention group was significantly less than that in the control group,indicating that the intervention group was able to maintain healthy eating habits.Conclusion Dietary intervention for postpartum women can effectively reduce postpartum weight retention,promote postpartum recovery,and have a long-term improvement effect on their diet quality.
