Relationship between consanguinity and depression in a south Indian population

Area of Science:

• Clinical Psychology
• Human Genetics
• Public Health

Background:

• Consanguinity, defined as marriage between relatives, is a cultural practice in various societies.
• Depression is a prevalent mental health disorder with significant public health implications.
• Understanding factors associated with depression is crucial for targeted interventions.

Purpose of the Study:

• To investigate the potential association between consanguine marriage and depression.
• To determine if this association persists after adjusting for demographic factors like age and sex.

Main Methods:

• A pilot study design was employed.
• Data was collected to assess marriage type (consanguine vs. non-consanguine) and depression status.
• Statistical analysis, including odds ratios with confidence intervals, was used to evaluate the association.

Main Results:

• Consanguine marriage showed a significant association with depression (Odds Ratio = 5.66, CI: 2.42-13.54).
• Age and sex were also found to be associated with depression.
• The adjusted odds ratio for consanguine marriage remained significant (7.66, CI: 3.93-19.45), indicating independent association.

Conclusions:

• Consanguine marriage is independently associated with an increased likelihood of depression.
• Further research is warranted to explore the mechanisms underlying this association.
• Findings may inform public health strategies addressing mental well-being in populations with high consanguinity rates.
