Adolescents aged 13\u201314\u00a0years self\u2010completed the questionnaires on these symptoms and potential risk factors and reported their own height and weight.

There were associations between overweight and obesity, but not underweight, and symptoms of asthma and eczema but not rhinoconjunctivitis. Vigorous physical activity was positively associated with symptoms of asthma, rhinoconjunctivitis and eczema in adolescents, but not children. Viewing television for five or more hours\/day was associated with an increased risk of symptoms of asthma, rhinoconjunctivitis and eczema in adolescents and symptoms of asthma in children.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions and Clinical Relevance<\/jats:title><jats:p>This study has confirmed the association between overweight and obesity and symptoms of asthma. It has extended these observations to include significant associations with symptoms of eczema, but not rhinoconjunctivitis. There are complex relationships between obesity, vigorous physical activity and sedentary behaviour and the symptoms of asthma, rhinoconjunctivitis and eczema in children.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cea.12024","type":"journal-article","created":{"date-parts":[[2012,9,25]],"date-time":"2012-09-25T02:41:31Z","timestamp":1348540891000},"page":"73-84","source":"Crossref","is-referenced-by-count":120,"title":["The association between <scp>BMI<\/scp>, vigorous physical activity and television viewing and the risk of symptoms of asthma, rhinoconjunctivitis and eczema in children and adolescents: <scp>ISAAC<\/scp> Phase Three"],"prefix":"10.1111","volume":"43","author":[{"given":"E.
