PMID 31406825WHAT IT FOUND
In 333 older Indonesian adults with hypertension, six factors predicted better health-promoting behaviour: self-efficacy, social support, knowledge, education, fewer perceived barriers and supportive situations.
These explained 36.9% of the variance. The study shows what correlates with healthy habits, not what causes them.
Key findings
01Self-efficacy was the strongest predictor of health-promoting behaviour, followed by social support.
02Higher education, better hypertension knowledge, fewer perceived barriers and more supportive situations were also significant positive predictors.
03Income and perceived benefits were related to behaviour but did not significantly explain variance in the final model.

What it does not show
Cross-sectional design cannot establish causation; predictors may be consequences of behaviour rather than causes. Self-reported data from face-to-face interviews may be subject to social desirability bias. The model explained only 36.9% of variance, meaning many other factors influence health-promoting behaviour. Findings are specific to older adults in urban Bengkulu City, Indonesia, and may not generalise to other populations or healthcare systems. No clinical outcomes such as blood pressure control or cardiovascular events were measured.
The easy way to misread this
Do not conclude that improving self-efficacy or social support will cause better health behaviour or lower blood pressure. This study only shows that these factors are associated with healthier behaviour in this population. Intervention studies are needed to test whether targeting these factors changes outcomes.
