Traditional postpartum customs in modern urban Chinese women and its association with dietary quality

Background & aims

Traditional Chinese customs practicing in postpartum yield mixed results on maternal health. The objectives of this study are 1) to depict the postpartum customs in Chinese lactating women in varied areas and 2) to explore its effects on dietary intake.

Method

This study is part of the “YI” study; data of 974 lactating women from ten cities of China were used. Food intake frequencies in the past month were assessed with the Food Frequency Questionnaire. The 24-h dietary recall was used to estimate nutrient intake and assess dietary diversity. Participants were also required to report in detail those traditional customs which they had practiced in postpartum, and word clouds were drawn according to the report frequencies of certain customs.

Results

In total, 49.9% of women practiced certain traditional customs in postpartum. A total of 159 customs were recorded, including 130 dietary customs. The most frequently reported customs included “avoid eating cold food” (n = 164), “no spicy food” (n = 121) and “avoiding food influencing breast milk secretion” (n = 42). The dietary diversity was not associated with practicing postpartum customs; however, women with customs had significantly higher intake frequencies of potato and yam, seaweed, fruits, livestock meat and other dairy products, yet a lower intake frequency of dark green vegetables. For nutrient intake, women who practicing certain practices were observed to have a significantly higher intake of energy, protein, carbohydrate, niacin, phosphorus, potassium and magnesium.

Conclusions

Traditional postpartum customs are still common in Chinese women and associated with dietary intake.
