Effectiveness of a motivated, action-based intervention on improving physical activity level, exercise self-efficacy and cardiovascular risk factors of patients with coronary heart disease in Sri Lanka: A randomized controlled trial protocol

Q: What is the clinical evidence from this study?

Study design: RCT. Population: Coronary heart disease (n=150). Intervention: Motivated, action-based intervention (HAPA framework) vs. Usual care. Primary outcome: Physical activity level (measured by IPAQ-SF).

Key result

Planned RCT evaluates a 12-week HAPA-based motivational intervention to improve physical activity in CHD patients.

n=150

Why the study?

Physical activity is recommended for secondary prevention in coronary heart disease, but many patients in Sri Lanka do not engage in adequate physical activity.

Does a culture-specific, motivated, action-based intervention improve physical activity levels, exercise self-efficacy, and cardiovascular risk factors in patients with coronary heart disease?

Population

150 patients with CHD from an inpatient cardiac unit in Batticaloa, Sri Lanka

Comparison

Culture-specific, motivated, action-based intervention plus usual care vs usual care alone

Design

Assessor-blinded randomized controlled trial protocol

Authors

Discussion

Member takes

Implication

Awaits completion before guiding culture-specific PA promotion in CHD; extends HAPA testing to South Asian populations.

Does a culture-specific, motivated, action-based intervention improve physical activity levels, exercise self-efficacy, and cardiovascular risk factors in patients with coronary heart disease?

Population

150 patients with coronary heart disease (CHD) from the inpatients cardiac unit of a hospital in Batticaloa, Sri Lanka

Intervention

Culture-specific, motivated, action-based intervention based on the health action process approach (HAPA) framework, consisting of a face-to-face preparatory session and 12-week sessions (three monthly group education and center-based group exercises, plus three 20-min individualized telephone follow-ups), in addition to usual care

Comparator

Usual care only

Outcome

Physical activity level, exercise self-efficacy, and cardiovascular risk factors assessed immediately after the 12-week intervention and at one-month post-interventionpatient reported

This protocol outlines an assessor-blinded RCT to evaluate a culture-specific, motivated, action-based intervention for improving physical activity and cardiovascular risk factors in Sri Lankan patients with coronary heart disease.

Limitations

General application of the findings may be limited because of the limitation of the population size in a certain district in Sri Lanka
Risk for recall bias on the self-reported outcomes, such as exercise self-efficacy

Karthijekan et al. (2022) conducted an RCT in Coronary heart disease (n=150). Motivated, action-based intervention (HAPA framework) vs. Usual care was evaluated on Physical activity level (measured by IPAQ-SF). A 12-week motivated, action-based intervention based on the HAPA framework is planned to be evaluated for its effectiveness in improving physical activity among patients with coronary heart disease.
