The association between pregnancy weight gain and the mother's weight at intervals following delivery was studied using the records of two clinics serving low-income populations. All the prenatal patients on whom complete data were available for a 2-year period were used. The 158 pregnant women gained a mean of 12.9 kg during their pregnancies; 44% gained more than 13.6 kg and 25% gained less than 9.1 kg. Three months after delivery the women showed gains significantly greater than those experienced by a nonpregnant comparison group during a comparable period. Maternal weight gain was determined by subtracting the infant's birth weight from the mother's total gain during pregnancy. Weight changes at three periods postpartum were compared among maternal weight gain tertiles. Sustained weight gains resulted in 39% of the women in the upper tertile being newly classified as overfat 1 to 3 months postpartum. Women in the high tertile had retained significantly more weight up through the sixth postpartum month. We conclude that a significant portion of maternal weight gain is likely to be retained, putting some women at risk of obesity.
利用两家为低收入人群服务的诊所的记录，研究了孕期体重增加与产后不同时间段母亲体重之间的关联。使用了在两年期间有完整数据的所有产前患者。158名孕妇孕期平均增重12.9千克；44%的孕妇增重超过13.6千克，25%的孕妇增重少于9.1千克。产后三个月，这些女性的体重增加明显高于同期未怀孕对照组女性的体重增加。母亲体重增加量通过从母亲孕期总增重中减去婴儿出生体重来确定。比较了产后三个时间段母亲体重增加三分位数组之间的体重变化。在增重最高三分位数组中，39%的女性在产后1至3个月新被归类为超重。增重最高三分位数组的女性在产后第六个月时体重保留明显更多。我们得出结论，很大一部分母亲孕期体重增加可能会保留下来，使一些女性面临肥胖风险。
