The figure above is a bar chart showing the prevalences and relative changes in prepregnancy body mass index (BMI) categories among women with a live birth, based on available data from 36 states, the District of Columbia, and New York City, for the years 2011 to 2015.

Prevalences and relative changes in prepregnancy BMI categories* among women with a live birth — 36 states, District of Columbia, and New York City,† 2011–2015

Abbreviation: BMI = body mass index (kg/m2).

* Prepregnancy BMI was categorized as underweight (BMI <18.5), normal weight (BMI 18.5–24.9), overweight (BMI 25.0–29.9), obesity class I (BMI 30.0–34.9), obesity class II (BMI 35.0–39.9), and obesity class III (BMI ≥40.0).

† Data are from 38 jurisdictions that utilized the revised birth certificate by January 1, 2011 and, thus, had prepregnancy BMI data during 2011–2015.
