Background
Diet is a potential modifier for chronic kidney disease (CKD) prevention and progression. Comprehensive dietary assessments from African cohorts, particularly West African populations, are sparse.
Methods
In the Diet, CKD, and Apolipoprotein L1 (DCA) study, participants were enrolled from seven West African centers. Up to three 24-hour dietary recalls were grouped into 23 categories using the West African Food Composition Table. Dietary patterns were identified using Principal Component Analysis (PCA) and Reduced Rank Regression (RRR). RRR modeled food intake against baseline SBP, DBP, urine protein, and eGFR, while PCA modeled six components (eigenvalues >1; variance explained >5%). Only factor loadings > ±0.2 were included. Adjusted Cox models assessed Hazards Ratios of dietary pattern consumption quartiles and CKD progression (>40% eGFR decline, dialysis, or transplant), and a composite outcome of CKD progression or all-cause mortality.
Results
Among 582 eligible participants, there were 137 CKD progression events and 168 composite events over a median 3-year follow-up. Higher consumption of the Soups and Sauces dietary pattern was associated with lower risk of CKD progression (Q3 vs Q1: 0.50 [0.38–0.66]; Q4 vs Q1: 0.41 [0.22–0.78]; p-trend=0.0014). However, greater adherence to the Bread and Palm Oil (Q3 vs Q1: 1.61 [1.10–2.34]; Q4 vs Q1: 1.51 [1.11–2.06]; p-trend=0.0023) and Meat and Seafood dietary patterns (Q3 vs Q1: 1.27 [1.02–1.58]; Q4: 1.70 [1.15–2.52]; p-trend=0.0054) was associated with a higher risk of the composite outcome.
Conclusion
In the DCA cohort, the Soups and Sauces pattern was associated with lower CKD progression risk; Bread/Palm Oil and Meat/Seafood (refined carbohydrates and animal proteins) patterns were associated with higher risk of the composite outcome. RRR-identified patterns have the added advantage of being linked to CKD-specific risk markers, complementing PCA. Findings likely reflect complex dietary interactions rather than one food group. Future research should explore these patterns as modifiable CKD risk factors in West Africa.
