Knowledge, perceptions and practices of lifestyle-modification measures among adult hypertensives in Nigeria.

Hypertension remains the most rapidly rising cardiovascular disease in Africa. This study was designed to evaluate the perception, knowledge and practices of Nigerian hypertensive patients regarding hypertension and lifestyle modification measures. Consecutive hypertensive patients attending the cardiac clinics of the University of Nigeria Teaching Hospital, Enugu, Nigeria, were recruited. A pre-tested structured interviewer-administered questionnaire was used to collect data. Questions were categorised to elicit patients' demographic characteristics, knowledge, perception and practice of various lifestyle-modification measures. chi(2) tests were performed. More than half (54.2%) of the 260 respondents had no formal, or just primary, education. About 25% were no longer taking their antihypertensive medication. Fifty per cent of the patients thought that hypertension was caused by stress. Most knew about the lifestyle measures through health personnel. More than 50% adopted the lifestyle-modification measures once they became aware of their effects. This study has shown a poor level of perception of hypertension and awareness of the lifestyle-modification measures through the mass media, but a high level of willingness to adopt the lifestyle measures. Concerted strategies are required to change the perception of hypertension and increase the awareness of the lifestyle-modification measures in this part of the world.
