目的：研究英国孕妇长期体重增加对妊娠的影响，并确定孕妇肥胖的潜在危险因素。设计：一项回顾性重复妊娠研究，研究孕妇从第一次成功怀孕到第二次怀孕体重的变化。243名母亲，她们都在第一次和第二次怀孕的前三个月内称过体重，没有一个在第一个孩子出生后12个月内怀孕。社会人口、行为、医疗、产科和围产期数据，以及产前测量的产妇体重和身高，都是从每个母亲的产科记录中提取的。一项全面的调查，在所有产前诊所使用的体重秤carried.RESULTS：后占老龄化的影响，有没有显着的长期增加，平均产妇体重后的第一次怀孕（95%置信区间：-0.82-0.28公斤）。虽然大多数母亲（70.8%）体重增加1.0公斤或以下，但24.7%的母亲体重增加超过1.54公斤。即使考虑到临床量表的最大误差，14.8%的母亲在第一次怀孕时体重增加了1.54公斤或更多。在第一次怀孕开始时BMI较高的母亲，在怀孕期间体重增加更多，生下更重的婴儿，怀孕间隔更长，从一次怀孕到下一次怀孕体重增加明显更多。怀孕对英国未经产妇女的平均体重增加几乎没有影响，（BMI大于或等于26.0，25.5%）。然而，怀孕可能与母亲体重的永久性增加有关，因为这是一个正能量平衡的时期，在此期间，一些妇女体重增加过多。其他因素，如孕前BMI，决定了长期体重增加是否真的发生。
OBJECTIVES: To investigate the impact of pregnancy on long-term weight gain of primiparous mothers in England, and to identify potential risk factors for maternal obesity.DESIGN: A retrospective, repeat-pregnancy study which examined the change in maternal body weight from the beginning of the first successful pregnancy to the beginning of the second.SUBJECTS: Two hundred and forty-three mothers, all of whom had been weighed during the first trimester of their first and second pregnancies, and none of whom had fallen pregnant less than 12 months after the birth of their first child.MEASUREMENTS: Sociodemographic, behavioural, medical, obstetric and perinatal data, together with antenatal measurements of maternal body weight and height, were extracted from each mother's obstetric notes. A comprehensive survey of weighing scales used at all antenatal clinics was undertaken.RESULTS: After accounting for the effect of ageing, there was no significant long-term increase in mean maternal body weight following the first pregnancy (95% Confidence Intervals: -0.82-0.28 kg). While most mothers (70.8%) gained 1.0 kg or less, 24.7% gained more than 1.54 kg. Even after accounting for the maximum error in clinic scales, 14.8% of the mothers gained 1.54 kg or more in association with their first pregnancy. Mothers with higher BMIs at the beginning of their first pregnancy, who gained more weight during pregnancy, gave birth to heavier babies and had longer intervals between their pregnancies, gained significantly more weight from one pregnancy to the next.CONCLUSIONS: pregnancy has little impact on the mean weight gain of primiparous women from England, who have a row prevalence of obesity (BMI greater than or equal to 26.0, 25.5%). Nevertheless, pregnancy may be associated with a permanent increase in maternal body weight simply because it is a period of positive energy balance during which some women gain excessive weight. Other factors, such as prepregnant BMI, determine whether long-term weight gain actually occurs.
