Malformations in 10,000 consecutive births in Tunis.

    Acta Paediatrica Scandinavica

    Summary

    Congenital malformations were studied in 10,000 infants. A high rate of consanguinity was linked to non-syndromic multi-malformed infants, suggesting a genetic influence.

    Area of Science:

    • Medical Science
    • Pediatrics
    • Genetics

    Background:

    • Congenital malformations are a significant cause of infant mortality and morbidity.
    • Understanding the prevalence and risk factors for malformations is crucial for public health initiatives.
    • Previous studies have indicated varying rates of malformations globally, with some regional differences noted.

    Purpose of the Study:

    • To determine the prevalence of congenital malformations in a large cohort of newborn infants in Tunis.
    • To investigate potential associations between malformations and factors such as consanguinity.
    • To compare malformation rates with existing literature.

    Main Methods:

    • A prospective study of 10,000 consecutively born infants (liveborn and stillborn) at a maternity hospital.
    • Detailed medical and social histories were collected, with a specific focus on parental consanguinity.
    • Infants were categorized based on the presence and type (major/minor) of malformations.

    Main Results:

    • A total of 396 infants (3.96%) had malformations, with 248 major and 148 minor.
    • Stillborn infants had a higher malformation rate (13%) compared to liveborn infants (3.7%).
    • A notable finding was a relatively high rate of neural tube defects (2.2/1000).
    • Consanguinity was significantly overrepresented (65%) in parents of infants with non-syndromic multiple malformations.

    Conclusions:

    • Congenital malformations represent a substantial health concern in the studied population.
    • The elevated rate of neural tube defects warrants further investigation and potential public health interventions.
    • Parental consanguinity is a significant risk factor for non-syndromic multiple congenital malformations, highlighting the role of genetic factors.
