OBJECTIVES: The aim of this study was to assess the association between screen-based (SB) behaviour and selected health complaints in adolescents and whether physical activity (PA) moderates this association.
METHODS: Data from the cross-sectional Health Behaviour of School-aged Children study collected in 2010 among Slovak adolescents (age 11-15 years, N = 8,042, 48.6 % boys) were used. Logistic regression models adjusted for age and gender were used to analyse the associations between watching TV, working with a computer or playing computer games and headache, backache, sleep difficulties, feeling low, irritability and feeling nervous. Next, we assessed the interactions of SB behaviours and PA regarding health complaints.
RESULTS: Watching TV more than 3 h is associated with increased chance of reporting headache, feeling low, being irritable or feeling nervous, while working with computer or playing computer games for more than 3 h does so in all of the explored health complaints. Being physically active does not moderate the associations of SB activities with health complaints.
CONCLUSIONS: SB behaviours are associated with health complaints among adolescents, and these associations are not moderated by PA.
