title: Association between glucose-6-phosphate dehydrogenase deficiency and neonatal jaundice: interaction with multiple risk factors.
abstract: This nonconcurrent cohort study was carried out to evaluate the association of neonatal jaundice with glucose-6-phosphate dehydrogenase (G-6-PD) deficiency and its interactions with other risk factors. The G-6-PD enzyme activity of 12,379 neonates was screened by a semi-quantitative fluorometric assay and double-checked by a quantitative method to identify a G-6-PD deficient cohort of 333 neonates. Matched with these on birth date, sex and delivery hospital were a G-6-PD normal cohort of 653 neonates. Neonatal jaundice was defined by a peak serum bilirubin (PSB) level of > or = 15 mg/dl. A significant association between G-6-PD deficiency and neonatal jaundice was observed in male but not female neonates. There was an inverse dose-response relation between G-6-PD activity and neonatal jaundice among male neonates. Both hypoxia/asphyxia and maternal hepatitis B surface antigen (HBsAg) carrier status were associated with an increased risk of neonatal jaundice among G-6-PD deficient but not G-6-PD normal male neonates. Based on multiple regression analyses, an additively synergistic effect on PSB level and severe jaundice (PSB > or = 20 mg/dl) was observed for G-6-PD deficiency and maternal HBsAg carrier status.
