Educational Attainment Promotes Fruit and Vegetable Intake for Whites but Not Blacks.

Abstract

Background: Although the protective effects of socioeconomic status (SES) on health behaviors are well-known, according to the minorities' diminished return theory, the health return of SES, particularly educational attainment, is systemically smaller for minorities than Whites. Aims. The current study explored Black-White differences in the effects of educational attainment and income on the consumption of fruits and vegetables.

Methods: This cross-sectional study used the Health Information National Trends Survey (HINTS) 2017 (n = 3217). HINTS is a nationally representative survey of American adults. The current analysis included 2277 adults who were either non-Hispanic White (n = 1868; 82%) or non-Hispanic Black (n = 409; 18%). The independent variables in this study were SES (educational attainment and income). The dependent variable was consumption of fruits and vegetables. Race was the focal moderator.

Results: In the overall sample, high educational attainment and income were associated with higher consumption of fruits and vegetables. Race moderated the effect of educational attainment but not income on the consumption of fruits and vegetables.

Conclusion: In line with the past research in the United States, Whites constantly gain more health benefits from the very same educational attainment than Blacks. The health gain from income is more equal across races than the health gain from educational attainment. Such diminished returns may be due to racism across institutions in the United States.
