The relationship between hostility and blood pressure in children

Area of Science:

• Pediatric health
• Psychology
• Cardiovascular research

Background:

• Hostility is linked to cardiovascular disease in adults.
• The relationship between childhood hostility and blood pressure requires further investigation.
• Obesity is a known factor influencing blood pressure.

Purpose of the Study:

• To examine the association between two dimensions of hostility (expressive and experienced) and resting blood pressure in children.
• To explore the moderating role of obesity in the hostility-blood pressure relationship.
• To compare findings in children with existing adult research on hostility and cardiovascular health.

Main Methods:

• 98 children aged 7–10 years completed hostility assessments (Buss-Durkee Hostility Inventory).
• Blood pressure and obesity levels were measured one week after hostility assessment.
• Multiple regression analyses and analyses of variance were employed to analyze the data.

Main Results:

• Expressive hostility was positively associated with blood pressure, a link that weakened when controlling for obesity.
• Experienced hostility showed a significant inverse relationship with systolic blood pressure.
• Obesity status influenced the association between expressive hostility and blood pressure.

Conclusions:

• Childhood hostility dimensions have distinct relationships with blood pressure.
• The findings suggest potential early-life predictors of cardiovascular risk.
• Further research is warranted to understand the long-term implications of childhood hostility and obesity on cardiovascular health.
