许多女性将她们一次或多次怀孕与成人肥胖的发展联系在一起。这种联系还没有得到充分的探索。这项纵向研究考察了孕妇在怀孕和产后期间的人体测量指标的变化。对77名孕妇在妊娠13周、25周和36周进行纵向调查，其中47名继续参与产后调查。每次访问时测量母亲的体重、身高和皮褶厚度(三头肌、二头肌、肩胛下、髂上和大腿中部)。根据前四种皮褶厚度的换算，估计孕妇的脂肪量。在第一次就诊时、产后6周和6个月时也测量了母亲的腰围和臀围。孕期(13~36周)增重10.9(SD 4.7)kg，增重4.6(SD 3.3)kg(P<；0.001)。从妊娠13周到产后6个月，脂肪量显著增加(2.6SD 4.5，P<；0.001)。产后6个月体重增加差异无统计学意义(1.1(SD 6.0)kg，P=0.20)。根据妊娠早期BMI，将受试者分为体重不足组、正常体重组、超重组和肥胖组。后三组比较用方差分析。肥胖组产后皮褶厚度、腰臀比、脂肪量的变化规律与其他两组比较，差异有统计学意义。总而言之，肥胖组有在产后发展为中心性肥胖的趋势。
Many women associate one or more of their pregnancies with the development of adult obesity. Such an association has not been fully explored. This longitudinal study examines the changes in maternal anthropometric indices during pregnancy and postpartum. Seventy-seven pregnant subjects were investigated longitudinally at about 13, 25 and 36 weeks gestation, of whom forty-seven continued taking part into the postpartum period. Maternal weight, height and skinfold thickness (triceps, biceps, subscapular, suprailiac and mid thigh) were measured at each visit. Maternal fat mass was estimated from the conversion of the first four skinfold thicknesses. Maternal waist and hip circumferences were also measured at the first visit and 6 weeks and 6 months postpartum. Weight and fat gain during pregnancy (13-36 weeks gestation) was 10.9 (sd 4.7) kg and 4.6 (sd 3.3) kg (P < 0.001) respectively. A significant increase in fat mass from 13 weeks gestation to 6-months postpartum was observed (2.6 (sd 4.5), P < 0.001). The increased weight at 6-months postpartum, however, was not statistically significant (1.1 (sd 6.0) kg, P = 0.20). Based on BMI in early pregnancy, the subjects were divided into groups of underweight, normal weight, overweight and obese. The last three groups were compared using ANOVA. The obese group showed a significant difference in the pattern of changes in the skinfold thickness, waist : hip ratio and fat mass at the postpartum period, in comparison with the other two groups. In conclusion, there is a tendency in the obese group to develop central obesity at the postpartum period.
