Association between maternal prepregnancy body mass index and risk of preterm birth in more than 1 million Asian American mothers.

ABSTRACT:

Background

Asian Americans are among the fastest growing subpopulations in the United States. However, evidence about maternal prepregnancy body mass index (BMI) and preterm birth among Asian Americans is lacking.

Methods

This population-based study used nationwide birth certificate data from the US National Vital Statistics System 2014 to 2018. All Asian American mothers who had a singleton live birth were included. According to Asian-specific cutoffs, maternal prepregnancy BMI was classified into underweight (BMI < 18.5 kg/m²), normal weight (BMI 18.5-22.9 kg/m²), overweight (BMI 23.0-27.4 kg/m²), class I obesity (BMI 27.5-32.4 kg/m²), class II obesity (BMI 32.5-37.4 kg/m²), and class III obesity (BMI ≥37.5 kg/m^2<
