The Stockholm Pregnancy and Weight Development Study is a prospective study of body weight changes in women, whose maternity unit charts were reviewed and who were then invited for a 1-year follow-up, including weigh-in sessions and questionnaires on dietary habits, physical activity and socio-demographic factors. Total weight gain during pregnancy was related to weight gain already during the first trimester. Women reporting previous weight cycling had slightly higher weight gain during pregnancy. Successful return towards pre-pregnancy weight was found more often in women with regular breakfast and lunch habits. Lactation had only a small effect on weight loss after delivery, independent of eating habits. Lack of physical activity was more common in women who had low lactation scores. Twenty-eight percent reported an increased interest in sweets during pregnancy; these women increased 1 to 2 kg more than others in weight during pregnancy. Postpartum weight retention was more affected by lifestyle changes during and after pregnancy than by factors before pregnancy.
斯德哥尔摩孕期与体重发展研究是一项关于女性体重变化的前瞻性研究。研究人员查阅了这些女性的产科病历，随后邀请她们进行为期1年的随访，包括称重环节以及关于饮食习惯、身体活动和社会人口学因素的问卷调查。孕期的总体重增加与孕早期的体重增加有关。报告有过体重波动史的女性孕期体重增加略高。有规律早餐和午餐习惯的女性更常成功恢复到孕前体重。无论饮食习惯如何，哺乳期对产后体重减轻的影响很小。泌乳评分低的女性缺乏身体活动的情况更为常见。28%的女性报告孕期对甜食的兴趣增加；这些女性孕期体重比其他人多增加1至2千克。产后体重滞留受孕期及产后生活方式变化的影响大于孕前因素。
