Acculturation and diet among Chinese American immigrants in New York City

Background: There are limited data on the social and cultural determinants of dietary intake in Chinese Americans. Over 560,000 New York City residents are Chinese American, and there has been a growing trend over the past 30 y of permanent migration from China to the USA. Objective: The purpose of this secondary data analysis is to describe associations between diet, measured by self-report, and diet quality, with level of acculturation in a cross-sectional sample of urban-dwelling Chinese American immigrants. Methods: This was a cross-sectional study involving 2071 foreign-born Chinese American adults. Acculturation was assessed using the Stephenson Multigroup Acculturation Scale, diet using a Chinese-adapted FFQ, and diet quality using the Alternative Healthy Eating Index (AHEI). Multivariable regression was used to assess associations between ethnic (ESI; Chinese) and dominant (DSI; American) society immersion scores with self-reported dietary measures. Results: No significant associations were found between acculturation and overall AHEI score. Higher ESI and DSI scores were associated with higher vegetable, fruit, and nut/legume scores; a higher DSI score only was associated with higher whole grain and PUFA scores. A 1-unit increase in the ESI score was associated with a 0.005 (P = 0.009) lower red and processed meat component score, whereas a 1-unit increase in DSI score was associated with a 0.01 (P = 0.025) higher red and processed meat component score. Conclusions: Assessment of acculturation level may help to tailor dietary strategies that are appropriate to what Chinese American immigrant communities are consuming to more effectively decrease the risk of chronic disease.
