【摘要】：目的了解合肥市妇女产后2年体重变化情况,探讨影响妇女产后2年内体重变化的因素,描述妇女产后2年内体重变化趋势,为促进产后后妇女体重恢复到孕前水平提供参考依据。方法以到合肥市某区妇幼保健站进行产后42天(d)体检的妇女为研究人群,按照纳入排除标准确定研究对象,签署知情同意书后,纳入研究队列进行历史-前瞻性观察队列研究。在研究对象产后42天进行基线资料收集,测量身高、体重,计算BMI值,在产后42天(d),6,12,18,24个月(m)对其进行随访调查。资料采用重复测量资料的方差分析、Bivariate过程进行相关分析、多因素Logistic回归分析。结果(1)研究对象共研究对象共418例,孕前平均体重(53.46±6.70)kg,产前体重平均值为(69.74±8.22)kg,孕期体重平均增加(16.33±5.26)kg。产后42d,6m,12m体重滞留均值分别为(7.14±4.04)kg,(6.81±5.02)kg,(5.19±3.82)kg,产后18m,24m体重变化值(产后18/24m体重-孕前体重)分别为(5.35±4.52)kg,(5.15±3.68)kg。产后42d,6m,12m,18m,24m恢复到孕前体重率分别为7.42%,15.38%,32.58%,24.89%,27.97%。(2)孕前BMI分组的妇女产后42d~12m,体重滞留呈递减趋势,产后12~24m,产后体重变化值呈增加趋势,超重/肥胖组妇女产后12~24m,体重变化波动较明显。(3)孕期增重是影响妇女产后2年内体重变化值的主要因素,孕期增重3组妇女产后42d,18m,24m体重变化值之间的差异有统计学差异(P0.05)。孕期增重和产后42d,18m,24m体重变化值之间存在显著相关性(P0.01),Pearson相关系数分别为0.635,0.298,0.341。(4)孕前BMI、睡眠时长、产后1年体重滞留也是影响妇女产后2年内体重变化的重要影响因素。结论将孕期增重控制在合理范围内,产后坚持母乳喂养、适量运动、适宜的睡眠时长可以有效地促进妇女产后体重恢复到孕前水平。
[Abstract]:Objective to investigate the changes of postpartum weight of women in Hefei, and to explore the factors influencing the changes of postpartum weight, and to describe the trend of weight change in women during postpartum. In order to promote women's weight recovery to pre-pregnancy level after postpartum, women who had physical examination at a district maternal and child health station in Hefei for 42 days postpartum were taken as the study group, and the study objects were determined according to the exclusion criteria. After signing the informed consent, the subjects were enrolled in the study cohort for a historical prospective observation cohort study. Baseline data were collected at 42 days postpartum, height and weight were measured, and BMI values were calculated. Follow up investigation was carried out on the 42nd day postpartum, the data were analyzed by variance analysis of repeated data and multivariate Logistic regression analysis. Results 1) 418 subjects were included in the study, and the results were as follows: (1) A total of 418 patients were enrolled in the study, and the data were analyzed by means of variance analysis and multivariate Logistic regression analysis. The average body weight before pregnancy was 53.46 卤6.70 kg, the average weight before delivery was 69.74 卤8.22 kg, the average weight gain during pregnancy was 16.33 卤5.26 kgs. the average body weight retention at 42d postpartum was 7.14 卤4.04 kg / kg 6.81 卤5.02 kg 5.19 卤3.82 kg / kg, and the mean weight change value of 18m / 24m postpartum was 5.35 卤4.52 kg / kg and 5.15 卤3.68 kg / kg respectively. The weight rates were 7.42% and 15.38%, respectively. The weight retention of the women who were divided into two groups of BMI before pregnancy (7.42%) and 32.58% (24.89%) at the end of the second trimester of pregnancy showed a decreasing trend of weight retention at 42 days postpartum. The change of postpartum body weight showed an increasing trend. The weight change of overweight / obese women was 1224 mpostpartum, and the fluctuation of body weight was obvious. The weight gain during pregnancy was the main factor that affected the change of postpartum body weight of women in postpartum 2 years. There was significant difference in weight change between pregnant women and postpartum 42d weight gain group (P 0.05). There was a significant correlation between gestational weight gain and postpartum 42d postpartum weight gain. Pearson correlation coefficient was 0.635v 0.2980.341.4) BMIs before pregnancy, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, sleep duration, and sleep duration. 1 year postpartum weight retention is also an important factor affecting the weight change of women within 2 years postpartum. Conclusion the weight gain during pregnancy should be controlled within a reasonable range. Proper sleep duration can effectively promote postpartum weight recovery to pre-pregnancy level.
