Dissecting the Causal Association between Body Fat Mass and Obsessive-Compulsive Disorder: A Two-Sample Mendelian Randomization Study.

Biomedical and environmental sciences : BES - 20 Jan 2026

Abstract excerpt

Objective: Previous studies link lower body mass index (BMI) with increased obsessive-compulsive disorder (OCD) risk, yet other body mass indicators may be more etioloically relevant. We dissected the causal association between body fat mass (FM) and OCD. Methods: Summary statistics from genome-wide association studies of European ancestry were utilized to conduct two-sample Mendelian randomization analysis....
