Television Viewing is Top of Screen Time for European Children and Increases Risk of Higher BMI and Consumption of Sugary Drinks
Television viewing and other screen activities seem to have substantial effects on not only young children’s consumption of sugary drinks but also on increased BMI and obesity. This is the conclusion of a new study on 11,000 children in eight European countries published by the European Journal of Clinical Nutrition.
The study is part of the EU-funded research project IDEFICS (Identification and prevention of dietary and lifestyle-induced health effects in children and infants) investigating diet, lifestyle and social determinants of obesity in 2 to 9-year-olds . Parents responded to questions about their children’s TV and screen habits, and consumption of sweetened beverages. At the same time, the children’s height, weight, and waist were measured. The study was performed from 2007-2010 in Sweden, Cyprus, Italy, Spain, Belgium, Germany, Hungary, and Estonia.
The results show that children who watched TV for longer when the study started tended to have the following features when they were examined two years later: a higher Body Mass Index, a greater waist to height ratios and a larger consumption of sugary drinks. For each additional hour a child spent watching TV per day, there was a 26% increased chance of them falling into the group with the biggest increase in waist to height ratio, and a 22% greater chance of being in the group with the biggest increase in BMI. Similarly, each additional hour of daily TV watching created a 19% greater likelihood of increased consumption of sugary drinks. Television viewing seems to have stronger effect than other screen activities such as computer use or videogames. The findings also suggest that TV constitutes the majority of screen time for children, and so remains an important factor in obesity rates in Europe.
The cohort of children built up during the IDEFICS study is being followed up in the FP7 EC funded I Family Study, which is investigating the determinants of food choice, lifestyle and health, not only in European children and adolescents but also their parents between 2012 and 2017.
The article Young children’s screen activities, sweet drink consumption and anthropometry: Results from a prospective European study has been published online by European Journal of Clinical Nutrition (20 November 2013).

2. The IDEFICS Study ran from September 2006 to February 2012 was funded under the EU’s Sixth Framework Programme. Researchers in 11 European countries collaborated on the research. The study delivered reliable data to make an international assessment of the problem of “obesity in children” possible. The focus of the IDEFICS Study lied in exploring the risks for overweight and obesity in children as well as associated long-term consequences. Beyond pure research, IDEFICS offered activities for health promotion and prevention in kindergartens and schools.
3. The I Family Study is an EC funded project under Framework 7 of the KBBE programme running from March 2012 to February 2017. It has 17 partners, working across 11 countries and with cohorts in 8 European countries – Germany, Italy, Sweden, Hungary, Cyprus, Estonia, Spain and Belgium.
4. The I Family Study has two strategic objectives:
(1) Understand the interplay between barriers against and drivers towards healthy food choice;
(2) Develop and disseminate strategies to induce changes that promote healthy dietary behaviour in European consumers especially adolescents and their parents.
