方法和结果在纵向研究中，1976-97 年婴儿出生登记的信息与研究成员的人口普查和死亡登记（1976-97 年）的数据相关联。从 1976 年开始收集出生体重，但在 20 世纪 70 年代数据并不完整。 44 813 名 15-45 岁女性在出生登记时首次记录的婴儿出生体重被用作暴露量。平均出生体重为 3210 克（SD 566 克）。研究期间平均出生体重变化不大（每年增加 4.6 克，95% 置信区间为 3.6 克至 5.6 克）。从每个男性出生体重中减去男性平均出生体重和女性平均出生体重（99 克）之间的差值。母亲的社会经济地位（住房保有权和汽车使用权）取自 1971 年人口普查。
Methods and resultsIn the longitudinal study, information from birth registrations of infants during 1976–97 is linked to data from the census and death registration (1976–97) for study members. Birth weight was collected from 1976 onwards, but during the 1970s the data were not complete. The first recorded birth weight of infants to 44 813 women aged 15–45 years at birth registration was used as the exposure measure. Mean birth weight was 3210 g (SD 566 g). The average birth weight changed little over the study period (4.6 g increase a year, 95% confidence intervals 3.6 g to 5.6 g). The difference between average male birth weight and average female birth weight (99 g) was subtracted from each male birth weight. Socioeconomic position (housing tenure and car access) of mothers was taken from the 1971 census.
