People living with hypertension are more likely to intend to follow a physician’s recommendation to take medication but less likely to plan lifestyle changes such as exercising, losing weight, eating better or cutting salt, researchers report in the journal Hypertension.
What the study examined
The research, conducted by teams at three universities including the Annenberg Public Policy Centre at the University of Pennsylvania, used the Health Belief Model to assess which beliefs and perceptions predict treatment intentions among a nationally representative sample. Investigators looked at how perceptions of personal risk, disease severity, the perceived benefits of treatment and barriers to communication with healthcare providers related to patients’ reported intentions.
The authors note that medication and lifestyle approaches are both integral to effective blood-pressure control, but their data suggest different psychological processes drive each behaviour.
“Medication and lifestyle changes are both essential components for treatment of hypertension, but our findings suggest they may be driven by different psychological processes,” said Yotam Ophir, associate professor of communication at the University at Buffalo and an APPC distinguished research fellow.
Key findings and practical implications
The study’s headline finding is straightforward: after a hypertension diagnosis, people tend to report higher intentions to take prescribed medications and lower intentions to adopt recommended lifestyle changes. The trend held even after accounting for whether participants intended to take medication.
Researchers also found that commonly used belief measures in health psychology — such as perceived susceptibility, severity and benefit — were better predictors of medication intentions than of intentions to change behaviours like diet or exercise. That suggests clinicians and public-health programmes may need to broaden their approach to motivate lifestyle change.
- Medication adherence: Diagnosis prompts stronger willingness to start or continue drug therapy.
- Lifestyle change: Diagnosis appears associated with reduced intention to pursue behavioural changes such as increased activity, weight control, healthier eating or salt reduction.
- Predictors differ: Traditional beliefs about risk and benefit predict medication intentions more reliably than lifestyle intentions.
Why this matters for patients and clinicians
Hypertension is a leading chronic condition where both pharmacological and non-pharmacological strategies are recommended. The study indicates that simply diagnosing hypertension and advising patients on risks may be insufficient to prompt the lifestyle adjustments that also reduce cardiovascular risk.
For clinicians, the findings point to the need for tailored conversations and supports that go beyond emphasizing risk and benefit. Practical strategies could include collaborative goal setting, addressing time and resource barriers, referring patients to allied health professionals (such as dietitians or physiotherapists), and providing structured follow-up to make incremental lifestyle changes more feasible.
For patients, the takeaway is that while taking prescribed medication is crucial, so too are sustained changes to diet, activity and weight. If making those changes feels difficult, discussing specific barriers with a healthcare provider or seeking community supports may help.
| Aspect | Reported association after diagnosis |
|---|---|
| Intention to take medication | Higher |
| Intention to adopt lifestyle changes (exercise, diet, weight, salt) | Lower |
The study authors emphasise that their results do not diminish the importance of either approach; rather, they highlight that different motivational levers may be required to support medication adherence and healthy behaviour adoption.
Health systems and practitioners designing hypertension management programmes should consider layered strategies that address practical and psychological barriers to lifestyle change while maintaining clear messaging about medication benefits when appropriate. Such an approach could improve overall blood-pressure control and reduce long-term cardiovascular risk.
