Birth Weight Percentiles – Using the same subset of US births as the 'small for gestational age' (SGA) calculations use, the percentile associated with every possible birth weight (in grams) was calculated, by gestational age and sex. These were attached to each birth record by gestational age, sex and birth weight to determine the exact percentile for each birth. Two birth weight percentile variables were calculated: BWTpctl_clin – using the clinical estimate of gestation, by birth weight, gestational and sex. BWTpctl_NVS – using the NVS imputed estimate of gestation, by birth weight, gestational and sex.

Benchmark birth weight percentiles were calculated using all US births from the CDC National Vital Statistics (NVS) natality files. The US data were subset to include only singleton births from 2000-2004 with known weight and gender with gestational age 20-44 weeks. Only the NVS imputed estimate of gestation was used for the calculations since CA does not report the clinical estimate at all. The US births were summarized by gestational age and sex, calculating various percentiles. These were matched to each birth record by gestational age and sex. The 10th percentile was then used to calculate 'small for gestational age' (SGA). In this way, two SGA variables were calculated: SGA_clinical – SGA using the clinical estimate of gestation, by gestational age and sex; SGA_NVS – SGA using the NVS imputed estimate of gestation, by gestational age and sex.
