Description: Are lay explanatory models of essential hypertension (HBP) the same as the biomedical explanatory model? A questionnaire designed to elicit explanatory models of hypertension was used in a semi-structured interview of 30 middle income, hypertensive and nonhypertensive black Americans in north central New Jersey. Content analysis of the recorded interviews revealed explanatory models that were clearly different from the scientific biomedical explanatory model of high blood pressure. Subjects identified "hyper-tension", which was described as a stress-related phenomenon and high blood pressure (HBP), which was characterized as a physical, measureable and temporary event. The two processes (HBP and hyper-tension) were identified regardless of the degree of biomedical information included in the explanatory model.

The factors most frequently associated with HBP and hypertension were dietary and socioemotional variables, respectively. In addition, the explanatory models included information regarding attitudes and behaviors that may be of value to the nurse when guiding patients in the management of high blood pressure. Generally, the participants considered hypertension to be chronic but not serious unless it led to high pressure. High blood pressure was considered as serious because it is potentially fatal, however it was not viewed as chronic. In addition, black cultural beliefs of the sample were not the sole influences on the formulation of the explanatory models. The other major factors influencing the explanatory models were information obtained from health care and media sources and observation of and discussions with family and friends.

It is evident that people tend to behave according to their beliefs. Hence, strategies to align biomedical and lay explanatory models of hypertension are needed. Therefore, approaches to HBP education may require change in order to dispel myths about hypertension and increase adherence to treatment regimens by those who are hypertensive.
