Popis: OBJECTIVE This longitudinal study aimed to investigate the characteristics and predictive risk factors of overweight among adolescents. The hypothesis was that baseline overweight predicted most overweight over time compared to other factors especially excessive internet use. SUBJECTS A sample of 621 youths were followed from age 14 (T0 Spring 2012) to age 16 (T1 Spring 2014) in Switzerland. Participants were divided into two groups according to their weight at the final assessment: overweight and non overweight. At T0 participants reported demographic health substance use and internet use data. A logistic regression was performed to assess the explanatory variables of overweight at T1. Data are presented as adjusted odds ratios (aORs) with 95 confidence interval. RESULTS The 2 year evolution showed a net BMI increase of 4.8. Overweight adolescents were significantly more likely to be male to live in an urban area to be on a diet and to report using the internet more than 2?h per day on weekends at T0. However with the addition of baseline overweight only the excessive use of internet on weekends remained as an explanatory variable. An adolescent who was already overweight at T0 had a more than 20 fold risk (aOR 21.04) of being overweight 2 years later. Moreover among adolescents becoming overweight between T0 and T1 internet use did not show any significant effect. CONCLUSION The risk of being overweight is mostly influenced by weight status at baseline compared to excessive internet use. Thus our results do not confirm the negative effect of internet on healthier activities. Internet use could at most reinforce an already existing risk of being overweight.International Journal of Obesity advance online publication 8 September 2015; doi:10.1038/ijo.2015.146.
