The Effects of Prepregnancy Body Mass Index and Gestational Weight Gain on Fetal Macrosomia Among American Indian/Alaska Native Women.

Objectives: The American Indian/Alaska Native (AI/AN) population is a high-risk group across many health indicators, including fetal macrosomia. We aimed to investigate the effects of prepregnancy body mass index (BMI) and gestational weight gain (GWG) on macrosomia and explore possible racial and geographical variations among AI/AN women.

Methods: This retrospective cohort study was conducted from the Pregnancy Risk Assessment Monitoring System in eight states (2004-2011) among live, singleton, term births to AI/AN women 20 years or older.

The Association Between Diabetes Mellitus Among American Indian/Alaska Native Populations with Preterm Birth in Eight US States from 2004-2011.

Objectives: Assess risk of preterm birth associated with diabetes mellitus (DM) among American Indian and Alaska Natives (AI/AN), a population with increased risk of DM and preterm birth, and examine whether this association differed by state of residence.

Methods: We used surveillance data from the Pregnancy Risk Assessment Monitoring System from 12,400 AI/AN respondents with singleton births in Alaska, Minnesota, Nebraska, New Mexico, Oklahoma, Oregon, Utah, and Washington from 2004-2011. We conducted multivariable logistic regression models to estimate the odds ratio adjusted for maternal age and prepregnancy BMI with all observations and then stratified by state.
