[Maternal risk factors associated with anencephaly]

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Genetics and Epidemiology

Context:

• Anencephaly presents a significant public health challenge with a high incidence rate of 2.82 per 1,000 live births.
• Maternal factors, including genetics, environment, and maternal health, are implicated in the etiology of anencephaly.
• This study investigated maternal risk factors for anencephaly in a case-control setting.

Purpose:

• To identify maternal risk factors associated with anencephaly.
• To assess the impact of various maternal exposures and characteristics on anencephaly occurrence.

Summary:

• A case-control study involving 23 cases of anencephaly and 46 controls was conducted.
• No significant associations were found between anencephaly and maternal age, pregnancy history, gestational pathology, high temperatures, occupation, or exposure to chemical/physical agents.
• A protective effect was observed with the administration of multivitamin preparations during gestation.

Impact:

• The findings highlight the potential protective role of multivitamin supplementation in preventing anencephaly.
• Understanding these factors can inform public health strategies and prenatal care guidelines.
• Further research is warranted to elucidate the mechanisms behind the protective effect of multivitamins.
