Abstract
Purpose The importance of dietary diversifcation for type
2 diabetes (T2D) risk remains controversial. We investigated
associations of between- and within-food group variety with
T2D, and the role of dietary diversifcation for the relation ships
between previously identifed dietary patterns (DPs) and T2D
among Ghanaian adults.
Methods In the multi-center cross-sectional Research on
Obesity and Diabetes among African Migrants (RODAM)
Study (n = 3810; Ghanaian residence, 56%; mean age,
46.2 years; women, 63%), we constructed the Food Variety
Score (FVS; 0–20 points), the Dietary Diversity Score
(DDS; 0–7 points), and the Diet Quality Index-International
(DQI-I) variety component (0–20 points). The associations
of these scores, of a “rice, pasta, meat and fsh” DP, of a
“mixed” DP, and of a “roots, tubers and plantain” DP with
T2D were calculated by logistic regression.
Results The FVS was inversely associated with T2D,
adjusted for socio-demographic, lifestyle, and anthropo metric
factors [odds ratio (OR) for T2D per 1 standard
deviation (SD) increase: 0.81; 95% confdence interval (CI)
0.71–0.93]. The DDS and the DQI-I variety component were
not associated with T2D. There was no association of the
“mixed” DP and the “roots, tubers and plantain” DP with
T2D. Yet, the “rice, pasta, meat and fsh” DP is inversely
