Evaluating the Relationship Between Medication Adherence, Dietary Practices, and Physical Activity in Heart...

Medication adherence is critical to improve quality of life, reduce transplant-related complications, and increase survival. Nonadherent health behaviors after heart transplantation lead to increased morbidity and mortality, decreased quality of life, increased medical costs, and overuse of healthcare services in heart transplant patients (HTR). This study examined the relationship between heart transplant recipients' medication adherence, dietary practices, and physical activity.

This cross-sectional study was conducted at a university hospital's Heart and Lung Transplant Outpatient Clinic. The sample included adult HTR who had undergone transplantation at least 6 months prior. Data were collected using the Basel Assessment of Adherence to Immunosuppressive Medication Scale, a Nutritional Behaviors Questionnaire, and the International Physical Activity Questionnaire Short Form Statistical analyses using SPSS 24.0, with significance set at p < 0.05.

Among 70 participants, 42.85% were non-adherent to immunosuppressive medications. Factors influencing adherence included age and time since transplantation. Dietary assessments revealed that while most patients practiced washing fruits and vegetables, adherence to other food safety measures was low. Physical activity levels indicated that 50% of participants were physically inactive, with high body mass index significantly correlating with lower activity levels. Patients with medication adherence had higher physical activity levels.

The study highlights the critical need for targeted interventions to improve medication adherence, dietary practices, and physical activity among HTR. Addressing these factors is essential for enhancing patient outcomes, reducing morbidity and mortality, and improving quality of life posttransplant. Further research is warranted to explore the barriers and facilitators influencing these health behaviors in diverse populations.
