-adrenergic vascular responsiveness, predominantly
in the SABPA black teachers’ cohort.

Their profile of risk for
left ventricular distension and chronic hypertensive status on a
pre-clinical level may elevate the risk for future cardiovascular
events. On a related note, differing cultural coping mechanisms
may enhance hypertensive risk, specifically in black teachers.
Limitations
Our study has some limitations, as important data, such
as sickle cell anaemia, CVD family history or self-reported
dietary intake, were not available to explain the prevalence of
hypertension. However, essential amino acids in DefS black men
from the SABPA study were disturbed compared to their white
counterparts.
40
DefS black men showed higher phenylalanine
and tyrosine (catecholamine precursor) levels, contributing to
higher blood pressure and structural vascular abnormalities.

Conclusion
Results indicated that blacks and whites have different and varied
coping styles based on their respective cultural backgrounds.
Blacks showed higher cardiovascular risk than whites, which
could have been a result of increasing defensiveness and chronic
depression observed among blacks over the three-year period.
Whites showed consistent spiritual-centred coping while utilising
avoidance or loss-of-control coping, with a trend of consistently
seeking less social support or isolation as a coping mechanism.
Differing cultural coping mechanisms reflected hypertension risk
in black teachers.
The consideration of chronic depression during the assessment
and treatment of hypertension could imply distinct treatment
programmes in groups with contrasting cultural backgrounds.
During counselling of depressed patients with hypertension, the
salutary effects of support and spiritual coping may be of great
importance. The beneficial effects of pastoral counselling may
also be considered.
This study would not have been possible without all the participants
who volunteered to be part of the SABPA study, and in-kind analyses of
the collaborators. Funding was obtained by the North-West University,
Potchefstroom, South Africa; the National Research Foundation (NRF) and
the Medical Research Council, South Africa; the Department of Education,
North-West Province; Roche diagnostics, South Africa; and the Metabolic
Syndrome Institute, France.
