Pathogenic analysis of post-transplantation obesity: A comprehensive systematic review

Table 4 Comparison of post-transplant obesity incidence and influencing factors by organ type

Index	Adult	Child	Activity	Diet	Ref.
Heart transplant	25-40 per cent of patients’ obesity post-transplantation	The lowest incidence of obesity post-transplantation, the lowest risk of obesity relative to other organ groups	Limited heart function and restricted exercise tolerance	The aggressive use of supplemental nutrition via feeding tubes	[23,24]
Kidney transplantation	21% of patients with CKD have obesity, and CKD patients are the main population for kidney transplantation	The highest incidence of obesity, a cumulative incidence 5-year post-transplantation of 27%	Reduced activity due to dialysis	Supplementary caloric intake via peritoneal dialysis	[22,23]
Liver transplantation	23% of liver transplant candidates have class I obesity, 10% have class II, and 4% have class III	The probability of obesity is lower than that of kidney transplantation and higher than that of heart transplantation	have a critical clinical status at time of transplantation in order to reduce activites	have a critical clinical status at time of transplantation in order to reduce food intake	[23,24]
