John Henryism and blood pressure differences among black men

Area of Science:

• Psychology
• Public Health
• Sociology

Background:

• The John Henryism legend reflects a cultural narrative for Black Americans facing stressors.
• Perceived control through hard work may influence health outcomes.
• Education is a known social determinant of health.

Purpose of the Study:

• To investigate the relationship between John Henryism, education, and blood pressure in Southern working-class Black men.
• To test the hypothesis that low education combined with high John Henryism predicts higher blood pressure.

Main Methods:

• A community probability sample of 132 Black men (ages 17-60) was surveyed.
• A scale measuring John Henryism (belief in controlling environment via hard work) was administered.
• Blood pressure was measured and analyzed in relation to education and John Henryism scores.

Main Results:

• Men with low education and high John Henryism scores exhibited significantly higher diastolic blood pressure.
• This group had higher blood pressure compared to men scoring high on both measures.
• Findings suggest an interaction between John Henryism, education, and physiological stress response.

Conclusions:

• John Henryism may influence autonomic arousal in response to stressors, particularly among those with lower educational attainment.
• The interplay between perceived control, socioeconomic factors, and health warrants further investigation.
• Culturally relevant concepts like John Henryism can provide insights into health disparities.
