Obesity increases atrial fibrillation risk in obese men, finds study

North Carolina: Type 2 diabetes (T2D) with obesity are at increased risk of atrial fibrillation, suggests a recent study in the journal JACC: Clinical Electrophysiology. Further, the study finds that men with greater BMI are at much greater risk of AF than women.

Obesity is a global health problem. It is associated with an increased AF risk in the general population but there is evidence that relationship may be different for those with diabetes. The study by Matthew J. Singleton, Wake Forest School of Medicine, Winston-Salem, North Carolina, and colleagues aimed to characterize the relationship between obesity and the risk of AF in diabetes.

For the purpose, the researchers used Cox proportional hazards models to examine the association between body mass index (BMI) and incident AF on study electrocardiogram in 10,074 participants (age 62.7 ± 6.6 years, 38.7% women, 62.2% white) from the ACCORD (Action to Control Cardiovascular Risk in Diabetes) trial. Among the participants 8.4% were normal weight, 29.0% were overweight, 53.1% were obese, and 9.5% were severely obese.
