title: Birth Outcomes by Infertility Diagnosis Analyses of the Massachusetts Outcomes Study of Assisted Reproductive Technologies (MOSART).
abstract: OBJECTIVE
  To evaluate assisted reproductive technology (ART) pregnancy outcomes by infertility diagnosis.
  
  
  METHODS
  ART data on women who were treated and gave birth in Massachusetts were linked to vital records and hospital utilization data. Live births were categorized by 8 mutually exclusive ART diagnoses. Risks of prematurity, low birthweight (LBW), small-for-gestational age (SGA), large-for-gestational age (LGA), pregnancy hypertension, gestational diabetes, prenatal hospitalizations, and primary cesarean delivery were modeled using logistic regression, adjusted for parental characteristics, treatment parameters, and plurality (adjusted odds ratios [AORs] and 95% confidence intervals); the reference group were pregnancies with the diagnosis of malefactor.
  
  
  RESULTS
  Among the 7,354 singleton and twin pregnancies, there were nonsignificant differences in the risks for LBW, SGA, or LGA. Significantly increased risks included gestational diabetes (ovulation disorders, AOR 1.80, 1.35-2.41), prematurity (ovulation disorders, AOR 1.36, 1.08-1.71; other factors, AOR 1.33, 1.05-1.67), prenatal hospital admissions (endometriosis, tubal and other factors, ovulation disorders, and uterine factors, AORs ranging from 1.66-2.68), and primary cesarean section (uterine factors, AOR 1.96, 1.15-3.36).
  
  
  CONCLUSIONS
  Although the infant outcomes of LBW, SGA, and LGA were generally similar across diagnosis groups, specific diagnoses had greater risks for prematurity, gestational diabetes, prenatal hospital utilization, and primary cesarean delivery. (J Reprod Med 2015;
