To examine whether pregnancy weight gains outside the Institute of Medicine (IOM) recommendations and rates maternal gain are associated with neonatal complications.In a cohort 45,245 women who delivered singletons at Kaiser Permanente Medical Care Program Northern California in 1996-1998 did not have gestational diabetes as 24-28 weeks gestation, we conducted nested case-control study three case groups: macrosomia (birth more than 4,500 g, n=391), hypoglycemia (plasma glucose less 40 mg/dL, n=328), hyperbilirubinemia (serum bilirubin 20 mg/dL or more, n=432) one control group (n=652). records were reviewed to ascertain woman's prepregnancy predelivery weight.Adjusting for age, race-ethnicity, parity, plasma screening value, difference between delivery time when last was measured, gained recommended by IOM times likely an infant (odds ratio [OR] 3.05, 95% confidence interval [CI] 2.19-4.26), nearly 1.5 (OR 1.38, CI 1.01-1.89), 1.43, 1.06-1.93) whose range. Women range 0.38, 0.20-0.70), but equally hyperbilirubinemia. Similar results obtained using other means categorizing during pregnancy.Maternal above increased risk outcomes studied.II-2.
