Main results


All 9 anthropometric measures height, weight, BMI, hip and waist circumference, waist-to-hip ratio and bioimpedance-derived fat mass, lean body mass and fat percentage were, as expected, positively associated with AF risk, however correlations between measures were also present. After multiple correction, lean body mass was the predominant anthropometric driver for AF risk, whereas none of the traditional obesity-related measures proved to have any independent influence. This questions the role played by fat in the AF etiology.
