Inflammation is implicated in the pathogenesis and progression of CKD. Diet modulates chronic inflammation and possibly kidney health. We evaluated the association of diet-related inflammation and kidney function among US Hispanic/ Latino adults.


Data were from participants in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), a population-based study of Hispanic/Latino adults 18-74 years old from 4 US communities, who were examined at visit 1 (V1) (2008-2011) and visit 2 (V2) (2014-2017) and had data on dietary intake and serum creatinine. Dietary inflammatory potential was assessed using the dietary inflammatory index (DII®). Scores were adjusted for total energy intake (E-DII®) and categorized into tertiles: T1 having the lowest dietary inflammatory potential, and T3 having the highest (most pro-inflammatory). Creatinine-based eGFR was calculated using the 2021 CKD-Epi equation. Primary outcomes were incident CKD (eGFR <60 ml/min/1.73m2 at V2 and ≥25% eGFR decline from V1 to V2) and rapid kidney function decline (RKFD) (≥30% decline in eGFR from V1 to V2). We excluded participants with eGFR <15 ml/min/1.73m2, and for incident CKD, those with eGFR <60 ml/min/1.73m2 at V1. Logistic regression models adjusting for study center and baseline socio-demographics, comorbidities, behavioral factors, medications, anthropometric measures, eGFR and albuminuria were used to compare E-DII® tertiles and determine odds ratio for incident CKD and RKFD.


Of 10,574 participants, median age was 49 years, 22% had diabetes, 46% had hypertension. Median eGFR was 101.7 ml/min/1.73m2. Median E-DII® was 0.18 (IQR -1.06 to 1.30). Over a mean follow-up of 6 years, 122 incident CKD and 196 RKFD events occurred. Participants with the most pro-inflammatory dietary patterns compared to the lowest had 2.2-fold higher odds of incident CKD (95% CI: 1.14 – 4.31) after adjusting for covariates. The E-DII® was not significantly associated with RKFD.


A pro-inflammatory dietary pattern is associated with a higher likelihood of incident CKD among US Hispanic/ Latino adults. To prevent kidney disease, US Hispanic/ Latino adults may opt to reduce intake of foods with higher pro-inflammatory potential (e.g., processed or fried foods, red meat, sweetened beverages).
