title: Child language interventions in public health: a systematic literature review.
abstract: OBJECTIVE
  Systematically review the literature on interventions in children's language in primary health care.
  
  
  METHODS
  One searched the electronic databases (January 1980 to March 2013) MEDLINE (accessed by PubMed), Scopus, Lilacs and Scielo. The search terms used were "child language", "primary health care", "randomized controlled trial" and "intervention studies" (in English, Portuguese and Spanish). There were included any randomized controlled trials that addressed the issues child language and primary health care. The analysis was based on the type of language intervention conducted in primary health care.
  
  
  RESULTS
  Seven studies were included and used intervention strategies such as interactive video, guidance for parents and group therapy. Individuals of both genders were included in the seven studies. The age of the children participant in the samples of the articles included in this review ranged from zero to 11 years. These seven studies used approaches that included only parents, parents and children or just children.
  
  
  CONCLUSIONS
  The mainly intervention in language on primary health care, used in randomized controlled trials, involved the use of interactional video. Several professionals, beyond speech and language therapist, been inserted in the language interventions on primary health care, demonstrating the importance of interdisciplinary work. None of the articles mentioned aspects related to hearing. There was scarcity of randomized controlled trials that address on language and public health, either in Brazil or internationally.
