  1. OW % = prevalence of new cases of overweight at follow-ups. Odds ratios (OR) are presented with 95 % confidence intervals (CI). 1-YEAR MODEL I is adjusted for age and occupation, 1-YEAR MODEL II: age, occupation, physical activity, social support, sleep duration. 5-YEAR MODEL I is adjusted for occupation, 5-YEAR MODEL II: occupation, physical activity. The number of subjects varied in the models due to partially missing data. 1-YEAR GAMING: men n = 979–1013 women n = 1940–2023. 1-YEAR EMAILING/CHATTING: men n = 979–1013, women n = 1937–2019. 5-YEAR GAMING: men n = 691–703, women n = 1269–1315. 5-YEAR EMAILING/CHATTING: men n = 691–703, women n = 1265-1310. ORs with a CI not including 1.00 are given in bold
