Brief Summary:
To investigate psychosocial and dietary influences on blood pressure in Blacks
Detailed Description:
BACKGROUND
Socioeconomic status as measured by education income andor occupation is generally inversely associated with hypertension-risk John Henryism research is designed to test the psychosocial stress hypothesis that low SES Blacks who are strongly predisposed to overcome difficult life circumstances through effortful active coping might have higher blood pressure than their more relaxed neighbors and that John Henryism and anger suppression are positively correlated in Blacks
The first two years of the project analyzed data collected on 1548 Black and white men and women in Edgecombe County North Carolina The Edgecombe County data were collected in 1983 to provide data for a representative sample of households to be used in evaluating the effectiveness of a community high blood pressure control program Approximately 50 percent of the sample was Black and 56 percent women In the first year measurements were made in all four race-sex groups of the effect-modifying role of John Henryism on education and on alternative measures of SES In the second year analyses were conducted on the degree to which job security marriage and socioeconomic mobility predict blood pressure in each race-sex group
DESIGN NARRATIVE
A survey was conducted of 2017 Black men and women in Pitt County North Carolina Study variables included age sex marital status socioeconomic status SES John Henryism behavioral predisposition to cope actively with psychosocial environmental stressors social support anger-coping style social desirability dietary variables including sodium potassium calcium and alcohol blood pressure height weight and pregnancy In the cross-sectional study blood pressure was the continuous outcome as measured by linear regression Three years after baseline all normotensive persons were re-examined in order to measure changes in blood pressure from baseline after exposure to selected psychosocial and dietary factors The study provided an estimate of the degree to which John Henryism social support anger-coping and dietary factors modify the association between SES and blood pressure in Blacks
The study was renewed in 1993 to re-examine the 1429 respondents 571 men 912 women with untreated mean diastolic blood pressure 95 mmHg at baseline and again at follow-up on changes in blood pressure during the intervening four to five years 1988-199293 The social variables included socioeconomic status John Henryism stress and social support the dietary variables included alcohol sodium potassium and calcium and the anthropometric variables included body mass index BMI and waisthip ratio WHR With an emphasis on SES physical activity dietary habits and cigarette smoking the predictors of weight gain and changes in patterning of body fat were also examined Multiple linear regression was the primary analytic tool used to study these longitudinal relationships In cross-sectional analyses which controlled for physical activity and other important variables the roles of insulin resistance in mediating associations between obesity and blood pressure and stress and blood pressure were also examined
