Food deserts and cardiovascular health among young adults.

Abstract

This study assesses the association between living in a food desert and cardiovascular health risk among young adults in the USA, as well as evaluates whether personal and area socioeconomic status moderates this relationship. A cross-sectional analysis was performed using data from Wave I (1993-1994) and Wave IV (2008) from the National Longitudinal Study of Adolescent to Adult Health. Ordinary least squares regression models assessing the association between living in a food desert and cardiovascular health were performed. Mediation and moderation analyses assessed the degree to which this association was conditioned by area and personal socioeconomic status. Sample of respondents living in urban census tracts in the USA in 2008. Young adults (n 8896) aged 24-34 years. Net of covariates living in a food desert had a statistically significant association with cardiovascular health risk (range 0-14) (β = 0·048, P < 0·01). This association was partially mediated by area and personal socioeconomic status. Further analyses demonstrate that the adverse association between living in a food desert and cardiovascular health is concentrated among low socioeconomic status respondents. The findings from this study suggest a complex interplay between food deserts and economic conditions for the cardiovascular health of young adults. Developing interventions that aim to improve health behaviour among lower-income populations may yield benefits for preventing the development of cardiovascular health problems.
