Abstract
Purpose In several studies, exploratory dietary patterns (DP), derived by principal component analysis, were inversely or positively associated with incident type 2 diabetes (T2D). However, fndings remained study-specifc, inconsistent and rarely replicated. This study aimed to investigate the associations between DPs and T2D in multiple cohorts across the world. Methods This federated meta-analysis of individual participant data was based on 25 prospective cohort studies from 5 continents inclu ...
Purpose In several studies, exploratory dietary patterns (DP), derived by principal component analysis, were inversely or positively associated with incident type 2 diabetes (T2D). However, fndings remained study-specifc, inconsistent and rarely replicated. This study aimed to investigate the associations between DPs and T2D in multiple cohorts across the world. Methods This federated meta-analysis of individual participant data was based on 25 prospective cohort studies from 5 continents including a total of 390,664 participants with a follow-up for T2D (3.8–25.0 years). After data harmonization across cohorts we evaluated 15 previously identifed T2D-related DPs for association with incident T2D estimating pooled incidence rate ratios (IRR) and confdence intervals (CI) by Piecewise Poisson regression and random-efects meta-analysis. Results 29,386 participants developed T2D during follow-up. Five DPs, characterized by higher intake of red meat, processed meat, French fries and refned grains, were associated with higher incidence of T2D. The strongest association was observed for a DP comprising these food groups besides others (IRRpooled per 1 SD=1.104, 95% CI 1.059–1.151). Although heterogeneity was present (I 2=85%), IRR exceeded 1 in 18 of the 20 meta-analyzed studies. Original DPs associated with lower T2D risk were not confrmed. Instead, a healthy DP (HDP1) was associated with higher T2D risk (IRRpooled per 1 SD=1.057, 95% CI 1.027–1.088). Conclusion Our fndings from various cohorts revealed positive associations for several DPs, characterized by higher intake of red meat, processed meat, French fries and refned grains, adding to the evidence-base that links DPs to higher T2D risk. However, no inverse DP–T2D associations were confrmed. ...
