Pregnancy and body weight development are intertwined in complicated patterns. Of the obese patients at our Obesity Unit, 73% had retained > 10 kg in connection with a pregnancy. For the general population the effect of a pregnancy on future weight development is surprisingly difficult to predict. In the Stockholm pregnancy and weight development study the estimated mean weight retention associated with a pregnancy and estimated 1 year after delivery was 0.5 kg but ranged from -12 to +26 kg. Weight increase during pregnancy was the strongest predictor for sustained weight retention 1 year later. Pre-pregnancy weight did not predict the weight development outcome. The lactation pattern had only a minor influence on weight development. Smoke cessation was an important predictor for sustained weight increase. More weight retention was observed in those women who reported an unfavorable change in lifestyle as regarded eating habits, meal patterns and physical activity. The eventual body weight after pregnancy seems to be more determined by the changes associated with that particular pregnancy than with the lifestyle before.
怀孕与体重变化以复杂的模式相互交织。在我们肥胖科的肥胖患者中，73% 的人体重因怀孕增加超过10千克。对于普通人群而言，怀孕对未来体重变化的影响出人意料地难以预测。在斯德哥尔摩怀孕与体重变化研究中，与怀孕相关且在产后1年估计的平均体重增加为0.5千克，但范围在 -12至 +26千克之间。孕期体重增加是1年后持续体重增加的最强预测因素。孕前体重并不能预测体重变化结果。哺乳模式对体重变化的影响很小。戒烟是持续体重增加的一个重要预测因素。据报告，在饮食习惯、用餐模式和体育活动方面生活方式有不利变化的女性体重增加更多。怀孕后的最终体重似乎更多地取决于与那次特定怀孕相关的变化，而非孕前的生活方式。
