The importance of dietary diversification for type 2 diabetes (T2D) risk remains controversial. We investigated associations between- and within-food group variety with T2D, the role relationships between previously identified patterns (DPs) T2D among Ghanaian adults.In multi-center cross-sectional Research on Obesity Diabetes African Migrants (RODAM) Study (n = 3810; residence, 56%; mean age, 46.2 years; women, 63%), we constructed Food Variety Score (FVS; 0-20 points), Dietary Diversity (DDS; 0-7 Diet Quality Index-International (DQI-I) component (0-20 points). these scores, a "rice, pasta, meat fish" DP, "mixed" "roots, tubers plantain" DP were calculated by logistic regression.The FVS was inversely associated adjusted socio-demographic, lifestyle, anthropometric factors [odds ratio (OR) per 1 standard deviation (SD) increase: 0.81; 95% confidence interval (CI) 0.71-0.93]. DDS DQI-I not T2D. There no association Yet, is (OR SD 0.82; CI 0.71-0.95); this effect slightly attenuated FVS.In population, between-food may exert beneficial effects glucose metabolism partially explains inverse
