Gender discrepancies in living related renal transplant donors and recipients.
Renal transplantation is the most successful treatment strategy for patients with ESRD to improve survival and quality of life. The study presented here examines the relationship of gender and living related (LR) transplantation donor and recipient rates in the United States. National data from the United States Renal Data System (USRDS) were used for this study. All LR transplants occurring between 1991 and 1993 among blacks and whites were included (N = 6193). Transplantation and donation rates for men and women were calculated. Poisson regression was used to calculate female/male transplantation and donation rate ratios. Overall, women were 10% less likely to receive a LR transplant than men (rate ratio [RR] = 0.90, P < 0.001). This gender difference increased over time from 1991 (Female/Male RR = 0.95, P = not significant [NS]) to 1993 (RR = 0.85, P < 0.001). In contrast, women were significantly more likely to donate a kidney than men (RR = 1.28, P < 0.001 and RR = 1.29, P < 0.001 among whites and blacks, respectively). Analyses by age subgroups revealed that only among ESRD patients aged 20 to 44 yr was the likelihood of receiving a LR kidney transplant equal for men and women. Higher donation rates among women compared with men were observed in all donor age and race subgroups except young blacks (aged 0 to 19 yr). Recipient gender appeared to influence donation rates. The female-to-male relative donation rates were higher when donations were to female, compared with male, recipients. This study of national data suggests an imbalance in LR donation and transplantation between men and women. Women are more likely to donate a kidney but are less likely to receive a LR transplant than men. Several potential explanatory factors are explored. These findings suggest a need for the development of gender-appropriate interventions to encourage donation among men and LR transplantation among women, to ultimately facilitate greater use of this ESRD treatment modality.
