globally, hypertension affects over one billion people, seven million of whom die annually as a direct result of it. Despite the presence of a variety of antihypertensive medications and health education on lifestyle modification, hypertension remains uncontrolled in Namibia. However, the state of patientsí knowledge, attitude and practices in Outapi district is unknown. This study determined the knowledge, attitudes and practices among hypertensive patients on the management of hypertension.
a cross-sectional, quantitative and analytical study was conducted from September to October 2016. The study involved 448 participants, obtained by a systematic sampling method. Structured, close-ended, interviewer administered questionnaire were used to collect data. Bivariate analysis was done to examine the association between dependent (controlled & uncontrolled blood pressure) and independent variables; Odds Ratios (ORs) and their 95% Confidence Intervals (CI) and p-values were calculated. Multiple logistic regression analysis models were also applied. Epi-info 7 software and Microsoft Excel were used to analyze the data.
there was no significant association on controlled blood pressure (BP) among
individuals who knew that eating less salt reduces hypertension (OR = 0.7,
95% CI = 0.4-1.3, p-value = 0.25), and among those who knew that losing weight
drop blood pressure (OR = 1.2, 95% CI = 0.8-1.7, p-value = 0.38). However,
knowing that hypertension can lead to kidney failure was significantly associated
controlled BP (OR = 2.22, 95% CI = 1.23-4.03, p-value = 0.007). Participants
who had positive attitudes to change their lifestyle practices were 1.8 times
more likely to have controlled BP compared to those who did not. The absence
of smoking 196 (85.6%), not taking alcohol 115 (50.2%), adherence to follow-up
dates 177 (77.3%) and treatment intake 180 (78.6%) among BP controlled participants
were significant. Controlled BP was significantly associated with the general
good practices 77.0% (OR = 4.2, 95% CI = 2.6-6.9, p-value = < 0.0001). There
was no association between good knowledge status and BP control (OR = 1.0,
95% CI = 0.7-1.6. p-value = 0.90).
positive attitudes and good practices towards the management of hypertension influence the control of hypertension. We recommended that health workers frequently offer health education to promote patientís knowledge, correct perceptions, beliefs and attitudes toward hypertension management.
