A Causal Model of Illness Perception and Change of Lifestyle Behaviors on Blood Pressure in Thais with Hypertension
Keywords:Illness perception, Hypertension, Thailand
Currently, a causal model between Illness perceptions and lifestyle modifications on blood pressure in Thais with hypertension in normal circumstance had not been examined. This study aimed to examine the direct and indirect effects of illness perception, lifestyle modification, and involved factors on systolic (model 1) and diastolic (model 2) blood pressures, using available data from a previous study conducted in 2015 among 660 Thais with hypertension from 4 Bangkok Public Health Centers and 2 primary care units. Data were analyzed using descriptive and path analyses. The results showed that both model 1 or systolic blood pressure model (Chi-square= 31.86, df= 35, p-value=0.620, RMSEA= 0.000, CFI=1.00, and GFI= 0.99) and model 2 or diastolic blood pressure model (Chi-square= 39.46, df= 35, p-value=0.277, RMSEA= 0.014, CFI=1.00, and GFI= 0.99) fitted with the evidence-based data. There were direct effects of illness perception with systolic and diastolic blood pressures. More exercise benefited with lowering systolic but not for diastolic blood pressures. Medication compliance benefited with lowering systolic and diastolic blood pressures. There was a difference between genders on diastolic blood pressure. This study indicated that Illness perception, exercise, and medication compliance were important for controlling high blood pressures
