目的了解中国女性产后体重滞留的现况并探索其影响因素。方法采用整群抽样,分别选取北京、苏州、广州产后第0~1、1~2、2~4、4~8个月的女性共578名。通过身体测量记录身高、体重。通过问卷调查并结合医疗记录收集调查对象的一般人口学资料和孕前体重、分娩时体重及相关孕产信息。结果调查对象孕前BMI为(20.8±2.7),产后BMI为(23.4±3.2),体重滞留数随时间逐渐减小。但至产后第4~8个月,仍有78.4%的女性体重滞留,且有53.4%的女性体重滞留数超过5 kg。孕期增重与产后体重滞留相关(P=0.015)。体重滞留者中学历较高者比例较大(P=0.044)。结论中国产后女性存在较为严重的体重滞留问题,孕期过度增重与产后体重滞留关系密切,对围产期女性从怀孕伊始即进行全方位的指导有助于改善体重滞留的现状。
Objective To understand the status of postpartum weight retention in Chinese women and to explore the influencing factors. Methods A total of 578 females from 0 to 1, 1 to 2, 2 to 4, and 4 to 8 months after delivery in Beijing, Suzhou and Guangzhou were selected by cluster sampling. Record body height and weight through body measurements. General demographic data and pre-pregnancy weight, birth weight and related maternal information were collected through questionnaires and medical records. Results Before pregnancy, the BMI was (20.8 ± 2.7) and the postpartum BMI was (23.4 ± 3.2). The body weight retention gradually decreased with time. However, at 4 to 8 months after delivery, 78.4% of women still had body weight retention and 53.4% of women had more than 5 kg of body weight retention. Weight gain during pregnancy was associated with postpartum weight retention (P = 0.015). The proportion of people with weight retention in the higher education was higher (P = 0.044). Conclusions There is a serious problem of weight retention in postpartum women in China. Excessive weight gain during pregnancy is closely related to postpartum weight retention. Guidance for perinatal women from the beginning of pregnancy helps to improve the status of weight retention.
