Low body mass index (BMI) was defined as < 25 kg/m². 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, leisure time physical activity, and the regularity 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.
