Review study finds negative association between time watching TV or playing video games and academic performance in children and adolescents

Researchers from the LIFE (Physical Activity, Fitness and Health) research group at the Universitat Jaume I, together with researchers from the Health and Social Research Center of the University of Castilla-La Mancha, have analysed 5,599 scientific articles and have concluded that there is a negative…

The study, published in Drug and Alcohol Dependence at the start of Alcohol Awareness Week (11 – 17 November) strengthens the evidence for a relationship between anxiety and later alcohol use as the researchers accounted for other factors such as adolescent smoking and cannabis use, and parental anxiety and alcohol use. Researchers used a longitudinal design to help disentangle the order of associations between generalised anxiety disorder and alcohol use. They also tested whether drinking to cope, a motive for drinking alcohol, influenced these associations. Using questionnaire and clinical interview data from more than 2000 participants, they found generalised anxiety disorder at age 18 was linked to frequent drinking, frequent bingeing, hazardous drinking, and harmful drinking at age 18. Generalised anxiety disorder continued to be associated with harmful drinking at age 21. Drinking to cope was also strongly associated with more harmful drinking, but it did not appear to influence associations between anxiety and alcohol use.Harmful drinking was measured using a special test developed by the World Health Association. On average, adolescents with anxiety drank at more harmful levels regardless of whether they tended to drink alcohol for coping reasons or not. Maddy Dyer, PhD student at the University of Bristol, commented: “Our most important finding was that the relationship between generalised anxiety disorder and harmful drinking at age 18 persists into early adulthood. Helping adolescents to develop positive strategies for coping with anxiety, instead of drinking alcohol, may reduce the risk of future harmful drinking. However, we cannot determine if the relationship is causal, because we used an observational study design.” Mark Leyshon, Senior Policy and Research Manager at Alcohol Change UK, said: “Our own research has shown that links between mental health problems, such as anxiety disorders, and alcohol are common and complex. For example, anxiety can be both a result of stopping drinking and a risk factor in beginning to drink too much, as this new study suggests. “We need more research to help us better understand the connections between alcohol and mental health,as well as high-quality, accessible, integrated support for substance misuse and mental health issues.” Source: University of Bristol, Full bibliographic information ‘Alcohol use in late adolescence and early adulthood: The role of generalised anxiety disorder and drinking to cope motives’ by Maddy Dyer, Jon Heron, Matthew Hickman, and Marcus Munafò, in Drug and Alcohol Dependence
