For some women pregnancy is a trigger factor for developing overweight and obesity. 73% of patients at the Obesity Unit, Huddinge University Hospital, indicated that they had retained more than 10 kg after each of their pregnancies; for this subgroup weight development after pregnancy was of obvious importance for their future health. However, in most studies mean weight retention after pregnancy is modest: 0.5-3.5 kg up to one year after delivery. Numerous studies have analysed factors explaining weight development after pregnancy and delivery, with a wide range of subjects, but overall it has been surprisingly difficult to identify strong predictors for weight development. The strongest factor is weight gain during pregnancy, but smoking cessation, a sedentary lifestyle and socio-economic factors also play a role. Pregnancy and weight development are intertwined in a complex pattern, which includes a change in lifestyle factors, such as eating behaviour, physical activity, smoking cessation and degree of lactation, but which are still not fully understood.
对一些女性来说，怀孕是导致超重和肥胖的触发因素。胡丁厄大学医院肥胖科73%的患者表示，她们每次怀孕后体重增加超过10千克；对于这一亚组人群而言，产后体重变化对其未来健康显然至关重要。然而，在大多数研究中，产后平均体重增加幅度不大：分娩后一年内增加0.5 - 3.5千克。众多研究分析了产后体重变化的影响因素，涉及广泛的研究对象，但总体而言，令人惊讶的是很难确定体重变化的有力预测因素。最强的因素是孕期体重增加，但戒烟、久坐不动的生活方式和社会经济因素也有影响。怀孕与体重变化以一种复杂的模式相互交织，其中包括生活方式因素的改变，如饮食行为、体育活动、戒烟和哺乳程度等，但这些因素仍未被完全理解。
