Food insecurity, particularly in food deserts, is associated with lower body mass index/weight-for-length in pediatric CF patients. Interventions to increase access to healthy and affordable food are essential to improve CF outcomes in these populations. Providers should routinely screen for food insecurity and proximity to food deserts in CF patients.
Food insecurity (FI) is defined as the limited or uncertain access to adequate food. One root cause of FI is living in a food desert. FI rates among people with cystic fibrosis (CF) are higher than the general United States (US) population. There is limited data on the association between food deserts and CF health outcomes. We conducted a retrospective review of people with CF under 18 years of age at a single pediatric CF center from January to December 2019 using demographic information and CF health parameters. Using a Geographic Information System, we conducted a spatial overlay analysis at the census tract level using the 2015 Food Access Research Atlas to assess the association between food deserts and CF health outcomes. We used multivariate logistic regression analysis and adjusted for clinical covariates and demographic covariates, using the Child Opportunity Index (COI) to calculate odds ratios (OR) with confidence intervals (CI) for each health outcome. People with CF living in food deserts and the surrounding regions had lower body mass index/weight-for-length (OR 3.18, 95% CI: 1.01, 9.40, p & LE; 0.05 (food desert); OR 4.41, 95% CI: 1.60, 12.14, p & LE; 0.05 (600 ft buffer zone); OR 2.83, 95% CI: 1.18, 6.76, p & LE; 0.05 (1200 ft buffer zone)). Food deserts and their surrounding regions impact pediatric CF outcomes independent of COI. Providers should routinely screen for FI and proximity to food deserts. Interventions are essential to increase access to healthy and affordable food.
