Loss of a Healthy Weight Advantage Among Mexican-American Children

Completed

• Conditions: Overweight and Obesity
• Interventions: Other: Nativity

• Registration Number: NCT03261882
• Lead Sponsor: University of North Carolina, Chapel Hill

Brief Summary

Although research indicates foreign-born Mexican-Americans possess a healthy weight advantage relative to U.S.-born Mexican-Americans, patterns are less clear for children and may be changing over time. The objective of this study was to examine whether the relationship between nativity and overweight/obesity has changed over time among Mexican-American children and to investigate the implications of this pattern on overweight/obesity disparities relative to non-Hispanic Whites. Using cross-sectional data from Mexican-Americans and non-Hispanic white children ages 4-17 years participating in the National Health and Nutrition Examination Surveys (1988-1994 (N=4,718) and 2005-2014 (N=7,269), the investigators used log-binomial regression to calculate prevalence ratios (PR) of overweight/obesity by nativity status adjusting for age, sex, householder marital status, householder education, survey period and a nativity by survey period interaction. The investigators also tested another covariate-adjusted model with a 3-level ethnicity-nativity variable that included Whites and an ethnicity-nativity by survey period interaction.

Primary Outcome Measures

Name	Time	Method
overweight/obesity	1988-1994 and 2005-2014	Body mass index (BMI) was calculated by dividing weight (kg) by height2 (m2), and overweight/obesity was defined as a BMI at or above the age- and sex-specific 85th percentile based on the CDC's BMI-for-age growth charts (yes/no).
