Structural and Contextual Patterns in Family Health History Knowledge among African American Adults: A Mixed-Methods...

Area of Science:

• Sociology
• Public Health
• Genetics

Background:

• Family health history (FHH) is a significant risk factor for chronic diseases.
• Ethnic minorities often exhibit lower FHH awareness, potentially exacerbating health disparities.

Purpose of the Study:

• To examine patterns in African American adults' family health history knowledge.
• To analyze how interpersonal communication with family members influences FHH awareness using social network analysis.

Main Methods:

• A mixed-methods social network analysis was employed.
• African American adults (n=37) completed interviews using a 3-generation family pedigree.
• Key outcome: identifying "personal health informants" who discuss their own health with the participant.

Main Results:

• Participants identified an average of 17% of their family network as personal health informants.
• Informants were more likely to be female, from the maternal side, have chronic conditions, and discuss health with the participant.
• Qualitative data revealed that open communication and disclosure facilitate FHH knowledge, often for preventive reasons or social support.

Conclusions:

• Communication and disclosure patterns significantly impact African Americans' family health history knowledge.
• Culturally relevant public health initiatives are needed to enhance FHH sharing, particularly for paternal relatives, siblings, and extended family.
