Comparison of birth weight between school health records and medical birth records in Denmark: determinants of discrepancies.

Jensen CB, Gamborg M, Heitmann B, Sørensen TI, Baker JL - BMJ Open (2015)

Bottom Line: During 1979-1991 when BW was recorded in 10 and 1 g intervals, mean BW did not significantly differ between the two registers.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.

Bland-Altman plots of birth weight (grams) in the CSHRR and the MBR according to MBR procedural changes. The solid line illustrates the mean difference and the dashed lines represent the ±1.96SDs. In the 1973–1978 plot, the mean difference was −287 g, with an SD of 215 g. In the 1979–1991 plot, the mean difference was −2 g, with an SD of 146 g. CSHRR, Copenhagen School Health Records Register; MBR, Medical Birth Register.

Mentions: The Bland-Altman plots of the differences in BW between the two registers per average BW generally showed good agreement (figure 1). In the 1973–1978 period, the rounding procedures in the MBR were apparent. In this period, the plot illustrates that the BW reports in the MBR were, on average, lower than the ones in the CSHRR.
