  • Data are given in means (SD), medians (IQR) or proportions %.

  • Heavy episodic drinking refers to an intake of five or more units at least once a month; possible alcohol problem: estimated from the Alcohol Use Disorder Identification Test score.

  • *Proportion of the total number of respondents of smoking status (N=325) and alcohol consumption (N=195).

  • BMI, body mass index; HbA1c, glycated hemoglobin; IFG, impaired fasting glucose; IGT, impaired glucose tolerance.
