Family history and socioeconomic risk factors for non-syndromic cleft lip and palate: a matched case-control study in a less developed country.

Abstract

A "social gradient in health" was seen to link oral malformation with diet components, and several socioeconomic and socio-demographic factors broadly encompassed in low socioeconomic status. Further characterization of risk factors will guide the assemblage of a pro-active counseling and prevention program for families at risk for non-syndromic cleft lip and cleft palate.
