GURGEL, Léia Gonçalves; VIDOR, Deisi Cristina Gollo Marques; JOLY, Maria Cristina Rodrigues Azevedo  e  REPPOLD, Caroline Tozzi. Risk factors for proper oral language development in children: a systematic literature review. CoDAS [online]. 2014, vol.26, n.5, pp.350-356. ISSN 2317-1782.


To conduct a systematic review of literature production related to risk factors for proper oral language development in children.


We used the terms "child language," "risk factors," and "randomized controlled trial" in MEDLINE (accessed via PubMed), Lilacs, SciELO, and The Cochrane Library from January 1980 to February 2014. Randomized controlled trials involving the study of some risk factors related to child language were included. Works with individuals who were not from the age group 0–12 years and presented no reliable definition of risk factors were excluded. The research findings were classified according to their theme and categorized methodological aspects.


We observed the lack of a standardized list of risk factors for language available for health professionals. The main risk factor mentioned was family dynamics, followed by interaction with parents, immediate social environment, and encouragement given to the child in the first years of life. It was also observed that organic hazards such as brain injury, persistent otitis media, and cardiac surgery, besides the type of food and parental counseling, may be related to language disorders.


More randomized controlled trials involving the evaluation of risk factors for child language and the creation of further studies involving children above 6 years of age and males are needed.
