  1. *Categories of Internet use: referential category of Internet use used in logistic regression modelling—“no use”, 1— “a few times a month or less often”, 2— “a few times a week”, 3— “everyday”; %–due to low frequencies of selected categories of Internet use, the categories were collapsed: 1—not more than a few times a week, 2—every day, referential category— “no use”, &p value for univariate logistic regression model; #p value for univariate logistic regression model; OR—odds ration; 95%CI—95% confidence interval; aOR—odds ration after adjusting for sociodemographic variables (age—as a continuous variable, gender, education level, place of residence, marital status, vocational status, net income per household member), BMI—body mass index
