Predictors of health-promoting behaviour among older adults with hypertension in Indonesia

Objectives:This study aimed to determine the predictors of health-promoting behaviour among older adults with hypertension in Bengkulu City,Bengkulu,Indonesia.Methods:A cross-sectional study was conducted in 333 older adults with hypertension,who were selected using multistage sampling method.Data were obtained by face-to-face interview with structured questionnaires.The questionnaires used in this study included the Health-Promoting Lifestyle Profile II(HPLP II),Hypertension Knowledge-Level Scale(HK-LS),Self-Rated Abilities for Health Practices Scale(SRAHP),Barriers to Health-promoting Behaviour Scales(BAS),Benefits to Health-Promoting Behaviour Scales(BES),Multidimensional Scale of Perceived Social Support(MSPSS)and Situational Influences Questionnaire(SIQ).Data were analysed by using multiple linear regressions.Results:The mean and standard deviation(Mean±SD)of each questionnaire were as follows:HPLP II,2.55±0.19;HK-LS,11.83±3.00;SRAHP,2.00±5.87;BAS,27.89±2.70;BES,34.29±2.29;MSPSS,60.35±8.12;and SIQ,47.71±6.66.According to the multiple linear regression model,36.9% of the variation in health-promoting behaviour among older adults with hypertension can be explained by six variables,namely,education,knowledge,self-efficacy,perceived barriers,social support and situational influences(adjusted R^(2)=0.369).Conclusions:High and good-quality education will increase the level of health-promoting behaviour,whereas barriers,such as expense and time requirement,can decrease it.Situational influences and support from family and friends can also influence the older adult's attempts to change their health behaviour.Increased self-efficacy will clearly result in improved health-promoting behaviour of older adults with hypertension.
