overweight and obesity in women of reproductive age are increasing and are often linked with excessive weight gain in pregnancy and weight retention after birth. Studies on spontaneous maternal weight trajectory after childbirth are scarce.
we describe women's spontaneous weight trajectory during the first six weeks of the postpartum period and its relationship between Body Mass Index and socio-demographical, behavioural and psychological variables.
data from 212 women who gave birth in three regional hospitals were collected prospectively between December 2015 and February 2016. Potential determinants were examined during pregnancy and the postpartum period at four and six weeks after childbirth. Descriptive statistics and a linear multivariate regression model were used. Early postnatal weight retention (PWR) was defined as the difference between the maternal weight six weeks after childbirth and the pre-pregnancy weight (kg).
mean PWR at six weeks after childbirth was 3.3kg (SD 4.1), with a range between -7 and +16.2kg; 81% reported some weight retention (PWR>0kg), and 36% showed a high weight retention (PWR≥5kg). Women with a BMI <25kg/m showed a significantly higher mean PWR six weeks after childbirth compared to women with a BMI ≥25kg/m (4.0kg versus 1.6kg, p=0.002). There was a significant correlation between maternal weight retention and gestational weight gain (GWG) (B=0.65, p<0.001) and pre-pregnancy body mass index <25kg/m (B=1.12, p=0.017), six weeks after childbirth.
weight retention six weeks after childbirth is associated with pre-pregnancy BMI and GWG, but contrary to expectations, lean women with excessive GWG tended to retain most weight after childbirth. No significant associations with several socio-demographical, behavioural and psychological variables were found.
weight management strategies around pregnancy should not be limited to overweight and obese mothers. Women with pre-pregnancy BMI <25kg/m require equal attention to prevent postnatal weight retention.
育龄女性超重和肥胖的情况日益增加，且往往与孕期体重过度增加及产后体重滞留有关。关于产后母亲体重自然变化轨迹的研究较少。
我们描述了产后六周内女性的自然体重变化轨迹及其与体重指数、社会人口统计学、行为和心理变量之间的关系。
2015年12月至2016年2月期间，前瞻性收集了在三家地区医院分娩的212名女性的数据。在孕期以及产后四周和六周时对潜在决定因素进行了检查。使用了描述性统计和线性多变量回归模型。产后早期体重滞留（PWR）定义为产后六周时母亲体重与孕前体重（千克）之间的差值。
产后六周时的平均PWR为3.3千克（标准差4.1），范围在-7至+16.2千克之间；81%的人报告有一定程度的体重滞留（PWR>0千克），36%的人表现出较高的体重滞留（PWR≥5千克）。与体重指数≥25千克/平方米的女性相比，体重指数<25千克/平方米的女性产后六周时的平均PWR显著更高（4.0千克对1.6千克，p=0.002）。产后六周时，母亲体重滞留与孕期体重增加（GWG）（B=0.65，p<0.001）以及孕前体重指数<25千克/平方米（B=1.12，p=0.017）之间存在显著相关性。
产后六周的体重滞留与孕前体重指数和GWG有关，但与预期相反，孕期体重增加过多的瘦女性产后往往滞留最多的体重。未发现与若干社会人口统计学、行为和心理变量有显著关联。
孕期体重管理策略不应局限于超重和肥胖母亲。孕前体重指数<25千克/平方米的女性需要同样关注以预防产后体重滞留。
