Longitudinal associations between sleep and BMI in a low-income, predominantly Black American sample.

ABSTRACT:

Objective

Black individuals and those experiencing socioeconomic disadvantage are at increased risk for sleep problems and obesity. This study adds to the limited extant literature examining longitudinal associations between objectively measured sleep and changes in body mass index (BMI) in Black Americans.

Design

Setting

Data were collected via interviewer-administered at-home surveys and actigraphy in Pittsburgh, PA.

Participants

Our sample comprised 1115 low-income,
