Objective: to describe sociodemographic and socioeconomic characteristics of patients with nonsyndromic cleft lip and/or palate (CL/P). Material and Methods: A cross sectional study with patients from 0-12 years old with nonsyndromic CL/P was carried out. The stydy examined patients (n-216) from two public hospitals (122 from Campeche and 94 from Hidalgo); 59.2% were from interior of Campeche Sate and 77.5% from interior of Hidalgo State. To recollect the data structured questionnaires were used which they contained several variables of different nature. Bivariates analyses were used to get the distribution differences between the two study places. Results: The highest frequency in orofacial defects was left unilateral cleft lip and palate (37%) in Hidalgo, it was observed higher frequency in the cleft lip plus cleft palate (p<0.05). In Campeche we observed worse socioeconimic contidions tha Hidalgo; bigger family size (p<0.0001), higher children percent age with CL/P in the lowest socioeconomic level quartile (P<0.05), lower schooling in the household head (p<0.001), father manual job (p<0.001)m birth at home (p<0.05). The Campeche patients had a higher percentage in the hereditary antecedents (p<0.001). To have a child with cleft lip and palate and previous abortion record were equally distributed in both places (p<0.05). We observed high reported percentage of folic acid consumption in both states (63,9% in Campeche and 61.7% in Hidalgo; (p<0.05). The paternal alcohol consumption were distributed equally among consumption were distributed equally Campeche and Hidalgo (p<0.05). It was not the same in the maternal alcohol consumption (p<0.001) cigarette smoking were higher in Hidalgo. Conclusions: Although, we observed the epidemiological characteristics are closed similar to other countries reports, there is certain variation between those variables among the two study places.
