Epidemiology of infants of diabetic mothers in indigent Micronesian population-Guam experience.

Diabetes complicating pregnancy has not yet been properly evaluated in Guam and the prevalence and morbidity of infants of diabetic mothers (IDM) in Micronesian population on Guam is described. The prevalence of IDM among the Micronesian population is 5.0% vs non-Micronesian's 3.7%. 82.5% were gestational diabetic mothers (GDM) diet controlled, 10.2% were GDM insulin controlled and 6.9% had Insulin Dependent Diabetes Mellitus. LGAs were 11% of IDMs in contrast to 6.4% of total births. Ten infants (NICU) spent total of 29 days on ventilator. Cesarean delivery, LGA, oxygen and ventilatory requirements were higher in Micronesian IDMs than in the non-Micronesian IDMs. The incidence is also higher in the Micronesian population (5.0%) compared to non Micronesian population (3.7%) on Guam. Micronesian IDMs were at higher risk for cesarean delivery, recurrent hypoglycemia, oxygen and ventilatory requirements than their non-Micronesian counterparts were. There is also a higher incidence of LGA among the Micronesian population and Chuukese had the highest incidence probably because they seek late or no prenatal care. We report 5.0% prevalence of diabetes during pregnancy in Micronesian population on Guam which imposes a significant economic burden on the local government's hospital resources. Micronesian IDMs were at higher risk for cesarean delivery, LGA, recurrent hypoglycemia, oxygen and ventilatory requirements than their non-Micronesian counterparts were. Chuukese had the highest LGA incidence in the study group. About 2/3rd of the IDM stayed 1110 extra days in hospital. IDMs accounted for the majority of expensive off-island transports.
