Lean is defined as a body mass index (BMI) of <25 kg/m² and a fat percentage in men of <20% and in women of <30%; normal-weight obesity is defined as a BMI of <25 kg/m² and a fat percentage in men of ≥20% and in women of ≥30%; and overweight is defined as a BMI of ≥25 kg/m² [5, 6]. A test for sex interaction was performed by adding a multiplicative variable to the full model of logistic regression analysis, adjusted for all sociodemographic factors, smoking and alcohol habits, physical activity, and the irregularity of meals. Values are presented as an adjusted (adj) odds ratio and a 95% confidence interval (CI). A -value (-value for interaction) of <0.05 was considered statistically significant.
