Socioeconomic aspects of these factors underlying stone formation require further investigation. We evaluated associations of neighborhood indices of food access and walkability with 24-hour urine measurements among patients with kidney stone disease (KSD). METHODS: We performed a retrospective analysis of adult patients with KSD evaluated with 24-hour urine collection (2001-2020). Based on the Food Access Research Atlas, low-income neighborhoods >0.5 miles (urban areas) or >10 miles (rural areas) from a full-service grocery store met the definition of low food access. Using the National Walkability Index (NWI), we identified neighborhoods with low walkability (NWI ≤5.75). We then assessed associations of these measures of food access and walkability with groupings of 24-hour urine abnormalities (stone risk factors and dietary factors, as defined by a commercial vendor; see Table) through multivariable logistic regression, as well as individual 24-hour urine measurements through analysis of covariance (ANCOVA) with adjustment for multiple testing. RESULTS: Among 1,119 patients with KSD and at least one adequate 24-hour urine collection based on urinary creatinine, 173 (15.5%) were from neighborhoods with low food access and 516 (46.1%) were from neighborhoods with low walkability. Using multivariable logistic regression (Table), patients from neighborhoods with low food access had higher odds of multiple (>1) stone risk factors (odds ratio: 1.78, 95% confidence interval: 1.03 to 3.09), but not multiple dietary factors. Patients from neighborhoods with low walkability did not have increased odds of multiple stone risk factors or dietary factors. Using ANCOVA, neighborhoods with low food access and or low walkability were not associated with significant differences in individual 24-hour urine measurements. CONCLUSIONS: Among patients with KSD, residence in a neighborhood with low food access was associated with multiple stone risk factors on 24-hour urine testing, though there were no significant differences in individual urinary measurements. The contribution of other sociodemographic factors to 24-hour urine abnormalities should be evaluated.
