Description:Background:
Healthy diet is essential in the management of chronic kidney disease (CKD) and preventing related comorbidities. Food outlet access has been studied in the general population; however, the influence of the local food environment on dietary intake among people with CKD has not been evaluated.
Objectives:
This study examined the associations of food outlet density and type of outlets with dietary intake in a multicenter cohort of racially and ethnically diverse patients with CKD.
Methods:
The Chronic Renal Insufficiency Cohort (CRIC) Study is a multicenter prospective study of patients with CKD that used a validated food frequency questionnaire to capture dietary intake at the baseline visit. This is a cross-sectional analysis of 2,484 individuals recruited in 2003-2006 from seven CRIC Study centers. Food outlet data was purchased to construct a count of the number of fast food restaurants, convenience stores, and grocery stores per 10,000 population for each geocoded census block group. Multivariable linear and logistic regression models were used to evaluate the associations between measures of food outlet availability and dietary factors.
Results:
The proportion of participants living in zero, low, and high food outlet density areas differed by gender, race/ethnicity, and income level. Among males, living in areas with zero or the highest number of outlets was associated with having the highest caloric intakes in multivariable models. Males living in areas with zero outlets consumed the highest levels of sodium and phosphorous. Females living in areas with zero outlets had the lowest average intake of calories, sodium, and phosphorous. Among low-income females, close proximity to more outlets was associated with higher calorie consumption. Among all participants, access to fast food restaurants was not associated with an unhealthy diet score, nor access to grocery stores with a healthy diet score.
Conclusions:
Average caloric and nutrient intakes differed by outlet availability; however, there were no strong associations with type of food outlet. This should be considered when developing food-focused public health policies.
