The sample was comprised of 1,680 adolescents (884 girls and 796 boys) aged 13, attending private and public schools in Porto, Portugal, during 2003\/2004. Adolescents completed questionnaires pertaining to demographic, social and behavioral characteristics, including the time spent watching television and playing computer games on week and weekend days. Logistic and proportional ordinal regressions showed that attending public schools, sleeping less time, using tobacco and presenting low levels of physical activity were factors associated with high media use. In boys living with one of their parents as well as living with younger and older parents were also associated with high media use. Besides the association with less healthier behaviours, we also found higher media use among adolescents from lower social classes and less structured families, which may increase their exposure to negative influence of the media.<\/jats:p>","DOI":"10.1590\/0102-311x00100313","type":"journal-article","created":{"date-parts":[[2014,4,3]],"date-time":"2014-04-03T13:51:29Z","timestamp":1396533089000},"page":"587-598","source":"Crossref","is-referenced-by-count":14,"title":["Characteristics associated with media use in early adolescence"],"prefix":"10.1590","volume":"30","author":[{"given":"Jos\u00e9","family":"Godinho","sequence":"first","affiliation":[{"name":"Universidade do Porto,  Portugal; Universidade do Porto,  Portugal"}]},{"given":"Joana","family":"Ara\u00fajo","sequence":"additional","affiliation":[{"name":"Universidade do Porto,  Portugal; Universidade do Porto,  Portugal"}]},{"given":"Henrique","family":"Barros","sequence":"additional","affiliation":[{"name":"Universidade do Porto,  Portugal; Universidade do Porto,  Portugal"}]},{"given":"Elisabete","family":"Ramos","sequence":"additional","affiliation":[{"name":"Universidade do Porto,  Portugal; Universidade do Porto,  Portugal"}]}],"member":"530","reference":[{"key":"ref1","series-title":"Generation M: media in the lives of 8-18 year-olds","author":"Rideout V","year":"2005"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/S1054-139X(02)00507-4","article-title":"The mass media and American adolescents? health","volume":"31","author":"Brown JD","year":"2002","journal-title":"J Adolesc Health"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"392","DOI":"10.1097\/00004583-200104000-00007","article-title":"Impact of media on children and adolescents: a 10-year review of the research","volume":"40","author":"Villani S","year":"2001","journal-title":"J Am Acad Child Adolesc Psychiatry"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"555","DOI":"10.1016\/j.ijheh.2007.07.003","article-title":"The impact of electronic media on mental and somatic children?s health","volume":"210","author":"Kappos AD","year":"2007","journal-title":"Int J Hyg Environ Health"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"123","DOI":"10.2307\/1602692","article-title":"The impact of home computer use on children?s activities and development","volume":"10","author":"Subrahmanyam K","year":"2000","journal-title":"Future Child"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"289","DOI":"10.1136\/adc.83.4.289","article-title":"The effects of television on child health: implications and recommendations","volume":"83","author":"Bar-on ME","year":"2000","journal-title":"Arch Dis Child"},{"issue":"52","key":"ref7","doi-asserted-by":"crossref","first-page":"1386","DOI":"10.1080\/00140130903067789","article-title":"Principles for the wise use of computers by children","author":"Straker L","year":"2009","journal-title":"Ergonomics"},{"key":"ref8","doi-asserted-by":"crossref","first-page":"387","DOI":"10.1001\/archpedi.160.4.387","article-title":"Is television viewing associated with social isolation?
