  1. OW % = prevalence of overweight. Odds ratios (OR) are presented with 95 % confidence intervals (CI). MODEL I: Adjusted for age, occupation, MODEL II: age, occupation, physical activity, social support, sleep duration, The number of subjects varied in the models due to partially missing data. GAMING: men n = 2515–2647, women n = 3806–4052. EMAIL/CHAT: men n = 2512–2643, women n = 3797-4039. ORs with a CI not including 1.00 are given in bold
