Dietary patterns and diabetes incidence in the Melbourne Collaborative Cohort Study

Abstract

The authors investigated the association of dietary patterns and type 2 diabetes in a 4-year prospective study of 36,787 adults in the Melbourne Collaborative Cohort Study (1990-1994). A total of 31,641 (86%) participants completed follow-up, and 365 cases were identified. Four factors with eigenvalues of greater than 2 were identified using the principal factor method with 124 foods/beverages, followed by orthogonal rotation. Variables with factor loadings having absolute values of 0.3 or greater were used in interpreting the factors. Odds ratios for diabetes incidence across quintiles of factor scores were computed by use of logistic regression, adjusting for age, energy intake, family his..
