Ethnic differences in fast-food advertising exposure and body mass index among Asian American/Pacific Islander and White young adults.

Fast-food advertising (FFA) is a potential contributor to obesity. Few studies have examined the relationship between FFA exposure and body mass index (BMI) among young adults. Furthermore, these studies have rarely examined ethnic differences in the relationship between FFA exposure and BMI, specifically across Asian American/Pacific Islander (AAPI) subgroups. This study aimed to investigate ethnic differences in the association between FFA exposure and BMI in a sample of predominantly AAPI young adults. Cross-sectional data were collected in 2018 from 2622 young adult college students (ages 18-25 years; 54% women) on O'ahu, Hawai'i. FFA exposure was assessed using a cued-recall measure. Multiple regression and analysis of covariance were used to analyze the data. A significant association was found between higher FFA exposure and higher BMI (p < 0.05; 2-tailed) in the entire sample, adjusting for ethnicity, other demographic variables, and levels of physical activity. However, when examined by ethnic group, the association between FFA exposure and BMI was not statistically significant. A statistically significant main effect of ethnicity on BMI was found. Native Hawaiian/other Pacific Islanders (NHPI) reported the highest mean BMI [27.07 (SD ± 7.74) kg/m2] compared with the other four ethnic groups (p < 0.001). The effect of ethnicity on FFA exposure was not found to be statistically significant. FFA exposure appears to adversely influence BMI in a population of predominantly AAPI young adults. Although we did not find ethnic differences in FFA exposure or in the association between FFA exposure and BMI, the current data make a case for similar future investigation with larger subgroup sample sizes. Regulations that curtail FFA exposure among young adults may be needed. Copyright © 2022 Asia Oceania Association for the Study of Obesity. Published by Elsevier Ltd. All rights reserved.
