Factors predicting therapeutic behaviors of middle-aged adults with hypertension in Binh Dinh Province, Vietnam
Inadequate adherence behaviors to therapeutic treatment cause failure of controlled hypertension and increased death and disability in hypertensive patients. Based on the Health Promotion model, this cross-sectional design aimed to investigate therapeutic behaviors of Vietnamese middle-aged adults with hypertension, and examine influences of participants’ perceived benefits, perceived barriers, perceived self-efficacy, and perceived nurse support to the therapeutic behaviors. Eighty two participants were randomly recruited. They were diagnosed as having primary hypertension and have visited the Out-patient Clinic of Cardiovascular Department at Binh Dinh General Hospital during the past three months. Self-report questionnaires were utilized for data collection. Descriptive analysis and standard multiple regression were used for research hypotheses testing.
Results showed high levels of therapeutic behaviors, perceived benefits, and perceived self-efficacy. Additionally, moderate levels of perceived barriers and perceived nurse support were also found. Regression analysis disclosed predicting power of perceived self-efficacy (β = .48, p < .001), perceived barriers (β = -.29, p < .01), and perceived benefits (β = .19, p < .05), which could explain up to 60% the variances of the therapeutic behaviors (R2 = .60, F[4,77] = 29.16, p < .001). Perceived nurse support was not significant in explaining the outcome (β = -.03, p > .05), although Pearson correlation was significant.
The findings clarify motivation for therapeutic behaviors among hypertensive middle-aged adults. These results will beneficial to clinical interventions as well as further research to approach hypertension control and promote optimal health in the population.
