比较学校健康记录中报告的出生体重（BW）信息与医疗出生记录中的BW，并调查母体和后代特征是否与任何差异相关。基于登记册的队列研究。丹麦，1973-1991年。该研究基于哥本哈根学校健康记录登记册（CSHRR）和医学出生登记册（MBR）中记录的BW。这些登记册通过丹麦个人身份证号码联系起来。使用t检验、Pearson相关系数、Bland-Altman图和κ系数对登记系统中的BW进行统计学比较。通过逻辑回归检验BW差异>100 g的几率。研究人群包括47534名儿童。 从1973年到1979年，当BW在MBR中以500 g间隔分组时，平均BW在寄存器之间存在显著差异。 在1979-1991年期间，当BW记录在10和1 g的间隔，平均BW没有显着差异的两个寄存器。 两个寄存器的BW高度相关（0.93-0.97）。体重差异的几率随着胎次、孩子回忆时的年龄和婚姻状况而显著增加（已婚妇女的孩子的几率最高）。总体而言，学校健康记录中的BW信息与医学出生记录中的BW非常一致，这表明丹麦哥本哈根学校健康记录中的BW报告通常是有效的。
To compare reported birth weight (BW) information in school health records with BW from medical birth records, and to investigate if maternal and offspring characteristics were associated with any discrepancies. Register-based cohort study. Denmark, 1973–1991. The study was based on BW recorded in the Copenhagen School Health Records Register (CSHRR) and in The Medical Birth Register (MBR). The registers were linked via the Danish personal identification number. Statistical comparisons of BW in the registers were performed using t tests, Pearson's correlation coefficients, Bland-Altman plots and κ coefficients. Odds of BW discrepancies >100 g were examined by logistic regressions. The study population included 47 534 children. From 1973 to 1979 when BW was grouped in 500 g intervals in the MBR, mean BW differed significantly between the registers. During 1979–1991 when BW was recorded in 10 and 1 g intervals, mean BW did not significantly differ between the two registers. BW from both registers was highly correlated (0.93–0.97). Odds of a BW discrepancy significantly increased with parity, the child's age at recall and by marital status (children of married women had the highest odds). Overall, BW information in school health records agreed very well with BW from medical birth records, suggesting that reports of BWs in school health records in Copenhagen, Denmark generally are valid.
