Obesity makes a substantial contribution to type 2 diabetes, according to a study published in the Journal of the American Heart Association. Study investigators examined the populationattributable fraction (PAF) for obesity on the prevalence and excess risk for diabetes. The unadjusted and adjusted hazard ratios (HRs) for obesity-attributable diabetes were examined for non-Hispanic White, non-Hispanic Black, and Mexican participants without diabetes at baseline from the Multi-Ethnic Study of Atherosclerosis (MESA). Data on body mass index and key covariates were available from 2000 to 2017. Data were included for 4,200 MESA participants. The researchers found that during a median follow-up of 9.2 years, incident diabetes mellitus occurred in 11.6% of MESA participants. The adjusted HR was 2.7 for obesity-related diabetes. Adjusted PAFs were 0.35 and 0.41 in 2001 to 2004 and 2013 to 2016, respectively.
