Consanguineous matings in the Egyptian population

Area of Science:

• Population Genetics
• Human Genetics
• Social Sciences

Background:

• Consanguineous marriages, unions between related individuals, are prevalent in many societies.
• Understanding the incidence and patterns of consanguinity is crucial for assessing potential genetic risks.
• Previous studies have indicated varying rates of consanguineous marriages globally and regionally.

Purpose of the Study:

• To determine the incidence of consanguineous marriages in the Egyptian population.
• To calculate the average inbreeding coefficient within this population.
• To identify variations in consanguinity rates across different geographic and socioeconomic strata.

Main Methods:

• A large-scale survey was conducted, ascertaining 26,554 individuals from diverse Egyptian populations.
• Data collection encompassed individuals from urban, suburban, and rural areas.
• Statistical analysis was employed to determine marriage incidence and inbreeding coefficients.

Main Results:

• The overall incidence of consanguineous marriages was found to be 28.96%.
• The average inbreeding coefficient was calculated at 0.010, considered high.
• Rural areas exhibited the highest incidence of consanguineous unions, with first cousin marriages being the most frequent type.

Conclusions:

• Consanguineous marriage is a significant demographic feature in Egypt, with a high prevalence.
• The observed inbreeding coefficient suggests a substantial level of genetic relatedness within the studied population.
• Targeted public health and genetic counseling initiatives may be warranted, particularly in high-incidence rural areas.
