Introduction: delayed primary language development is present in 6 to 10% of children aged less than 6 years and is a common cause of pediatric consultation, a problem that can be managed once the risk factors are known. Objectives: to identify the biological or personal factors associated to the delayed primary language development in children aged 18 months to 5 years. Methods: analytical case-control study performed in children aged 18 months to 5 years, who were attended to in the neuropediatric service of "Juan Manuel Marquez" pediatric hospital because of delayed language development, in the period of January 2010 through July 2011, with respect to a control group of healthy children. Results: delayed primary language development was more frequent in boys at a ratio of 1:4.6, who were diagnosed at average age of 3.05 (0.95 %) years and had family history of language impairments (p= 0.001) and neuropsychiatric diseases (p= 0.012). They also presented antecedents of malformations, traumas and dystermia at birth (p= 0.007) and more retardation in the development of laterality (p= 0.025). Conclusions: risk factors for the delayed primary language development were considered as masculine gender, family history of language disorders and neuropsychiatric diseases, delayed laterality and postnatal pathological events.
