Practice and Sociodemographic Factors Influencing Self-Monitoring of Blood Pressure in Ghanaians with Hypertension.

BACKGROUND

In sub-Saharan Africa, the prevalence of hypertension has assumed epidemic levels and currently accounts for numerous complications such as stroke, heart failure, and kidney damage. Management of hypertension involves both drug and nonpharmacological approaches. Self-monitoring of blood pressure is an important nonpharmacological approach that facilitates early detection of deteriorating blood pressures and complications.

AIMS

We determined the practice and sociodemographic factors influencing self-monitoring of blood pressure among Ghanaians with hypertension.

METHODS

In a cross-sectional design, we recruited four hundred and forty-seven (447) Ghanaians with hypertension receiving care at the hypertensive Outpatient Department (OPD) Clinics of the Medical Department at the Korle-Bu Teaching Hospital (KBTH). The respondents were sampled using a simple random sampling technique of balloting without replacement. A structured questionnaire was used to gather data on the practice of self-monitoring of blood pressure and sociodemographic factors influencing self-monitoring in the respondents. We also measured some anthropometric and haemodynamic indices of the respondents. The data was entered in Microsoft Excel 2010 and exported into SPSS 21.0 to aid with the data analysis. A chi-square test and Student's -test analysis were done to determine the relationship between the practice of self-monitioring and other sociodemographic variables. Data analayses were conducted at a significant level (alpha 0.05) and power of 95% confidence. Thus, < 0.05 was considered statistically significant.

RESULTS

The practice of self-monitoring of blood pressure was 25.3% with more female respondents claiming to practice self-monitoring as compared to their male counterparts (28.6% vs. 20.7%). Awareness of self-monitoring of blood pressure was associated with increased practice of self-monitoring of blood pressure. Health workers (46.8%), colleague patients (39.8%), relatives/spouses (6.7%), and the media (6.7%) were identified as the sources of information about self-monitoring of blood pressure. Awareness of self-monitoring, level of education, valid health insurance, occupation, income levels, and marital status had a significant relationship with self-monitoring of blood pressure among the respondents. Thus, respondents with higher education, awareness of self-monitoring, valid health insurance, formal employment, and higher income were likely to monitor their blood pressure.

CONCLUSION

Several sociodemographic factors influence the practice of self-monitoring of blood pressure in Ghanaians with hypertension. Thus, targeted hypertension education and social-cognitive interventions should focus on these sociodemographic factors so as to improve self-monitoring of blood pressure in order to reduce the complications of hypertension.
