Abstract
Introduction:
Research showing that place of birth (POB) predicts excess weight gain and obesity risk among Latino adults has not prompted similar research in Latino children, although childhood is a critical period for preventing obesity.
Objective:
To identify differences in obesity risk among Latino children by POB.
Methods:
Longitudinal cohort observational study on public school children self-identified by parent/guardian as Latino in grades K-12 for school years 2006–07 through 2016–17 with measured weight and height (n = 570,172students; 3,103,642observations). POB reported by parent/guardian was categorized as continental United States [not New York City (NYC)] (n = 295,693), NYC (n = 166,361), South America (n = 19,452), Central America (n = 10,241), Dominican Republic (n = 57,0880), Puerto Rico (n = 9687), and Mexico (n = 9647). Age- and sex-specific BMI percentiles were estimated based on established growth charts. Data were analyzed in 2020.
Results:
Prevalence of obesity was highest among US (non-NYC)-born girls (21%) and boys (27%), followed by NYC-born girls (19%) and boys (25%). Among girls, South Americans (9%) had the lowest prevalence of all levels of obesity, while Puerto Ricans (19%) and Dominicans (15%) had the highest prevalence. Among boys, South Americans also had the lowest prevalence of all levels of obesity (15%), while Puerto Ricans (22%) and Mexicans (21%) had the highest. In adjusted models, obesity risk was highest in US (non-NYC)-born children, followed by children born in NYC (p < 0.001). Immigrant Latino children exhibited an advantage even after controlling for individual and neighborhood sociodemographic features, particularly Dominicans, South Americans, and Puerto Ricans.
Conclusions:
The heterogeneity of obesity risk among Latino children highlights the importance of POB.
