This study examined the John Henryism hypothesis on blood pressure in an urban population of middle-aged black men and women. The population in which James and colleagues first demonstrated the importance of John Henryism on blood pressure was located in the rural south, where it was demonstrated that less educated John Henry active copers had [...]

Descriptive statistics for the entire sample, split by gender, are shown in Table 1. T-tests revealed a significant difference on BMI between men and women, with women exhibiting greater BMI. There were no other significant differences found on any of the other descriptive variables measured on a continuous scale. The majority (86%) of the sample [...]

Subjects
This study used a sample constructed by a merging of two cohorts from studies examining risk factors for hypertension conducted from 1986 to 1991. Subjects were recruited from Miami-Dade County, FL, through community blood pressure screenings and advertisements in newspapers. All subjects were healthy native English speakers. If a subject was taking a prescribed blood [...]

INTRODUCTION
Population-based surveys indicate that black adults in the United States experience disproportionately higher rates of hypertension than their white counterparts, with 38.0% of black men compared to 28.9% of white men, and 41.0% of black women compared to 24.7% of white women suffering from hypertension. Consequently, a variety of hypotheses have been proposed to account [...]

Our study sample comprised 191 black men and women attending an historically black university. These subjects were comparably distributed by sex and college level. Each subject underwent BMI determination and selected body images that best represented who they thought they were and how they would like to be. Also, each subject answered 20 questions about [...]

There were 96 male students [mean age 20.2 ± (SD) 2.7 years] and 95 female students [mean age 20.2 ± (SD) 1.4 years]. Of these 191 students, 45 were freshman, 48 sophomores, 50 juniors and 48 seniors.

Measures
We measured each student’s height (inches) and weight (pounds). For students age 20 years and older, we calculated body mass index: BMI (kg/m2) = [weight (pounds) / height2 (inches2)] x 703. For students under the age of 20 years, we used the Nutstat module of Epilnfo to determine BMI, BMI percentile and BMI z-score.
