Objective: This study aims to evaluate the association between health related
quality of life and disease state knowledge among hypertensive populations in
Methods: A cross sectional descriptive study was undertaken with a representative cohort of hypertension patients. Using prevalence based sampling techniques, a total of 385 hypertensive patients were selected from two public hospitals in Quetta City, Pakistan. The Hypertension Fact Questionnaire (HFQ) and the European Quality of Life scale (EQ-5D) were used for data collection. Statistical Package for the Social Sciences 16.0 was used to compute descriptive analyses of patients’ demographic and disease related information. Categorical variables were described as percentages while continuous variables were expressed as mean ± standard deviation (SD). Spearman’s rho correlation was used to identify any association between study variables.
Results: The mean (SD) age of the patients was 39.02 (6.59) years, with 68.8% being males (n=265). The mean (SD) duration of hypertension was 3.01 (0.93) years. Forty percent (n=154) had bachelor’s degrees with 34.8% (n=134) working in the private sector. Almost forty one percent (n=140) had a monthly income of more than 15000 Pakistan rupees and 75.1% (n=289) resided in urban areas. The mean EQ-5D descriptive score (0.46±0.28) and EQ-VAS score (63.97±6.62) indicated lower health related quality of life (HRQoL) in our study participants. The mean knowledge score was 8.03 ± 0.42 while the correlation coefficient between HRQoL and knowledge was 0.208 (p< 0.001), indicating a weak positive association.
Conclusions: Results of this study highlight hypertension knowledge is weakly associated with HRQoL, suggesting that imparting knowledge to patients does not necessarily improve HRQoL. More attention should be given to identifying individual factors that affect HRQoL.
