VALDIVIA ALVAREZ, Ileana et al. Exposure to television viewing and delayed primary language development in children younger than 5 years. Rev Cubana Pediatr [online]. 2014, vol.86, n.1, pp. 18-25. ISSN 0034-7531.

Introduction: in addition to the impact of the genetic findings at present, recent studies emphasize two factors of environmental impact such as verbal interaction between father and child, and the child exposure to the electronic media (television, video, and computers) with interesting implications on the language development. Objective: to evaluate the child exposure to television viewing as a risk factor in the development of language in children aged 18 months to 5 years. Methods: analytical case-control study of children aged 18 months to 5 years, who were attended to in the neuropediatric service of "Juan Manuel Marquez" pediatric hospital because of language impairment, from January 2010 to July 2011, and a control group of healthy children. Results: the primary language impairment is more common in children from university education families in over 80 %, who presented with longer (p= 0.0001) and earlier (p= 0.001) exposure to television viewing. Conclusions: risk factors for primary language impairment were considered to be exposure to television viewing before the 2 years of age for more than two hours a day.
