目的：本研究的目的是评估孕前体重指数、孕期体重增加和产后体重滞留对产妇15年后体重保留的预测作用。研究方法和步骤：斯德哥尔摩怀孕和妇女营养(SPOWN)研究是对1984-1985年分娩的妇女的长期跟踪研究(n=2342)。参与者最初填写了关于他们在怀孕前、怀孕期间和怀孕后一年的饮食和锻炼习惯、社会环境等方面的问卷。人体测量学数据也被抽样。15年后，这些女性被邀请参加后续研究。他们收集了人体测量数据，并提出了类似的问题。563名女性参与了这项为期15年的跟踪研究。样本被分成三组进行检查：1)孕前超重和正常体重；2)孕期低、中、高体重增加者；3)孕后一年的低、中、高体重保留者。结果：超重女性在孕期没有增加更多的体重，也没有在一年的随访中保持更多的体重。妊娠期体重增加高的人在1年和15年的随访中保留了更多的体重。高体重保留者在怀孕期间增加了更多，并在15年的随访中保持了下来。56%的怀孕期间超重的人最终进入了超重保留组。讨论：怀孕前超重的女性产后体重滞留的风险并不比正常体重的女性高。因此，在怀孕期间或怀孕后，体重控制计划的目标或重点不一定是最初超重的女性。在15年的随访中，高体重增重者和高体重保持者都有更高的BMI，尽管在1年的随访中，只有56%的怀孕期间高体重增重者也被归类为高体重保持者。产后一年末的体重保持预示着15年后的未来超重。
Objective: The aim of this study was to evaluate how well prepregnancy BMI, gestational weight gain, and postpartum weight retention predict retention of weight 15 years later among parous women.Research Methods and Procedures: The Stockholm Pregnancy and Women's Nutrition (SPAWN) study is a longterm follow-up study of women who delivered children in 1984 to 1985 (n = 2342). The participants initially filled out questionnaires about their eating and exercise habits, social circumstances, etc. before, during, and at I year after pregnancy. Anthropometric data were also sampled. Fifteen years later, these women were invited to take part in the follow-up study. Anthropometric measurements were collected, and similar questions were asked. Five hundred sixty-three women participated in the SPAWN 15-year follow-up study. The sample was divided into groups to examine three presumably critical time periods: 1) overweight and normal weight before pregnancy; 2) low, intermediate, and high weight gainers during pregnancy; and 3) low, intermediate, and high weight retainers at I year after pregnancy.Results: The overweight women did not gain more weight during pregnancy or retain more weight at I year follow-up. High weight gainers during pregnancy retained more weight at the 1-year and the 15-year follow-ups. High weight retainers had gained more during pregnancy and retained it at the 15-year follow-up. Fifty-six percent of the high weight gainers during pregnancy ended up in the high weight retainers group.Discussion: Women who are overweight before pregnancy do not have a higher risk of postpartum weight retention than normal weight women. Thus, it is not necessarily the initially overweight woman who should be the target or focus of weight control programs during or after pregnancy. Both high weight gainers and high weight retainers had higher BMI at the 15-year follow-up, although only 56% of the high weight gainers during pregnancy were also classified as high weight retainers at the 1-year follow-up. Weight retention at the end of the postpartum year predicts future overweight 15 years later.
