Abstract
            Introduction: This study aimed to assess the functional status of kidney and liver transplant  patients and identify factors associated with improvement in their condition.  
  Methods: A descriptive-analytical study was conducted involving 375 patients, 195 kidney  and 180 liver transplant recipients, from Imam Reza Medical Training Center and transplant  specialists’ offices in Tabriz. Data were collected using the “Personal-social factors of patients”  questionnaire and “Karnofsky Performance Scale Index”, and analyzed using SPSS version  24. Descriptive (mean, standard deviation) and inferential statistical tests (independent t-test,  ANOVA, Pearson correlation), with significance set at P<0.05.  
  Results: Liver transplant patients had an average functional status score of 80.06±9.54, while  kidney transplant patients scored 77.64±8.53, a significant difference. Among kidney recipients,  men demonstrated better functional status, while among liver recipients, women performed  better. Poor economic status, unemployment, and low education was associated with lower  functional levels. In contrast, patients reporting strong social support and physical activity  exhibited higher functional status scores. An inverse relationship was found between age and  functional status, while time since transplantation showed a direct relationship.  
  Conclusion: Employment status, income level, social support, and housing conditions  significantly influence post-transplant functional status. These findings highlight the need for  targeted interventions to improve patient outcomes.
