  1. Fulltext. Hispanic origin and neural tube defects in Houston/Harris County, Texas. I : Descriptive epidemiology.

    Article - En anglais


    High prevalences of anencephaly and neural tube defects (NTDs) have recently been recorded for several Texas counties bordering Mexico.

    In addition, a few investigators have reported Hispanics to be at elevated risk for NTDs (anencephaly and spina bifida).

    Factors contributing to this risk have not been established.

    The authors conducted a study of NTDs in Harris County, Texas, to determine the prevalence of each defect.

    Prevalence was established by identifying cases among resident live births and fetal deaths (stillbirths at =20 weeks) occurring from April 1,1989, through December 31,1991.

    Using multiple case ascertainment methods, 59 cases of anencephaly and 32 cases of spina bifida were detected, resulting in prevalences of 3.8 (95% confidence interval 2.9-4.9) and 2.0 (95% confidence interval 1.4-2.8) per 10,000 live births, respectively.

    The ratio of anencephaly prevalence to spina bifida prevalence was 2 : 1 in 1989,1 : 1 in 1990, and 3 : 1 in 1991, with a significant difference in 1991.

    The female : male prevalence ratio was 1.0 for spina bifida and 2.2 for anencephaly, and was higher still for anencephaly among non-Hispanics (prevalence ratio=5.6).

    For each defect, Hispanics experienced a prevalence approximately three times that of non-Hispanics.

    This ethnic difference was greater for males with anencephaly and for females with spina bifida.

    For anencephaly, the Hispanic : white/Anglo prevalence ratio (4.2) and the African-American : white/Anglo ...
