Duration of daily TV/screen watching with cardiovascular, respiratory, mental and psychiatric health: Scottish Health Survey, 2012-2013

BackgroundThe link of duration of TV and/or screen watching and chronic health conditions by subtypes is unclear. Therefore, the relationship between TV and/or screen watching hours and cardiovascular, respiratory, mental and psychiatric health and well-being (happiness) was assessed in an independent population-based survey to identify correlations of various hours with health conditions.MethodsData was retrieved from the Scottish Health Survey, 2012-2013. Information on demographics, lifestyle factors, self-reported health conditions and TV and/or screen watching duration in both Scottish adults and children was collected by annual household interviews. Chi-square test and survey weighted logistic and multi-nominal modelling were performed.Results5527 (57.0%) Scottish adults aged 16-99 watched TV and/or screen daily for 3 + h on average. There was a trend toward more hypertension, angina, stroke, diabetes, chronic obstructive pulmonary disease and poor self-rated health and mental health. Reporting watching TV and/or screen for 4 + h, for 5 + h and for 8 + h was associated with higher rates of heart attack, heart murmur or other heart troubles and abnormal heart rhythms, respectively. 414 (20.7%) Scottish children aged 4-12 watched TV and/or screen for 3 h or more. They tended to have poor self-rated health and life difficulties perceived as emotional and behavioural problems.ConclusionThere were associations between various hours of TV and/or screen watching (3 + h) and poor health observed both in Scottish adults and children. Future educational and public health programmes minimising TV and/or screen watching in order to protect cardiovascular, respiratory, mental and psychiatric health might be considered.
