Objectives: Postpartum weight retention is a short- and long-term risk factor for overweight and obesity in women. This study evaluated dietary patterns and their impact on postpartum weight retention among lactating women in south-central China. Methods: A total of 305 lactating women were included. A 24-h recall method on three consecutive days was used to collect dietary information. Furthermore, the principal component analysis was performed to explore the main dietary patterns. The association between the postpartum weight retention and dietary patterns was assessed using a general linear regression model. Results Two food patterns were obtained. Lactating women with dietary pattern 1 mainly ate red meat, coarse cereals, and fresh vegetables (leafy). Those with dietary pattern 2 mainly ate fresh vegetables (non-leafy), soymilk, and bacteria and algae. The mean energy, protein, fat, and carbohydrate intakes of the highest quartile (Q4) of both patterns exceeded the RNI, while the calcium, selenium, vitamin A, vitamin B1 and vitamin C nutrients intakes in the highest quartile (Q4) of both patterns were lower than recommended. The dietary pattern 2 (B = –0.523, 95%CI –0.948 to –0.099) was negatively associated with postpartum weight retention. Conclusions:china This study identified two dietary patterns among lactating women in south-central China. A diet characterized by high intakes of fresh vegetables (non-leafy), soymilk, and bacteria and algae was negatively associated with postpartum weight retention.
