Sleep and media habits in school children and adolescents

Forskningsoutput: TidskriftsbidragArtikel


The aim was to investigate the effects of sleep, television use and texting and computer habits on overweight, enjoyment of school and feelings of tiredness at school in school-age children and adolescents. This cross-sectional study was conducted in Sweden on school children aged 6-16. A questionnaire was distributed to the children (n=3011 in survey I; n=204 in survey II). Children who slept less than the median length of time reported enjoying school to a lesser degree. Fewer hours of sleep were found to be associated with having a bedroom television using the television or computer more than 2 hours a day, being tired at school and having difficulties in sleeping and waking up. Overweight and obesity were found in 15.8% of the study population; obesity alone was found in 3.1%. Relationships between lifestyle factors and overweight were studied using multivariate logistic regression analysis. Having a bedroom television and using the television more than 2 hours per day were found to be associated with overweight but using the computer more than 2 hours a day was not. About 61% of the students aged 16 reported checking Facebook or social media at least once a day and 27% reported doing so for more than 10 times a day. One fourth of the students aged 16 had a habit of sending or receiving text messages at night at least once a week. Texting at night and frequent checking of Facebook and social media sites were related to sleep problems.
