Cross-sectional study (one time point).

  • Attrition (final N): N=100 (0% attrition)
  • Age: Mean=53.5 years (21 years to 75 years)

  • The results obtained in the general index among women was high, whereas men achieved middle scores. Women scored slightly higher in the individual indicators, particularly prophylactic behaviors and healthy practices. Women complied more conscientiously with the prescriptions, attended regularly planned tests, avoided infections and looked for medical information about disease prevention. They also tried to get sufficient rest and sleep and avoided overwork.
  • The whole group took care of proper nutrition, used diet to prevent atherosclerosis, avoided salt and sugar and significantly reduced their intake of meat and processed meat with preservatives
  • They seek to think positively and live in stable family relationships and friendly relationships. They avoided experiencing strong negative emotions and stress.
Author Conclusion:

Heart transplant patients adopted health-related behaviors at a high level, indicating that post-surgery education should place even greater emphasis on shaping healthy eating habits, prevention-oriented behavior and positive mental attitudes. Heart transplant patients should obtain professional, interdisciplinary assistance to shape healthy behaviors.

Relevance Questions
  1. Would implementing the studied intervention or procedure (if found successful) result in improved outcomes for the patients/clients/population group? (Not Applicable for some epidemiological studies) Yes
  2. Did the authors study an outcome (dependent variable) or topic that the patients/clients/population group would care about? Yes
  3. Is the focus of the intervention or procedure (independent variable) or topic of study a common issue of concern to dieteticspractice? Yes
  4. Is the intervention or procedure feasible? (NA for some epidemiological studies) Yes
