Rationale: Kidney transplant recipients are at increased risk of metabolic complications. A Body Shape Index (ABSI) has emerged as a potential marker of visceral fat and metabolic burden, particularly in settings where advanced body composition analysis is not available.

Objective: to assess the relationship between ABSI, metabolic parameters, dietary intake, and clinical factors in kidney transplant recipients.

Methods: A cross-sectional study was conducted in 65 adult kidney transplant recipients. Anthropometric indices of central obesity (ABSI, AVI, WHtR, and Conicity Index) were calculated. Dietary intake was assessed using dietary interviews and the FFQ-6 questionnaire. Clinical and treatment-related data were analyzed. Statistical significance was set at p < 0.05.

Results: Mean BMI was 24.9 ± 4.34 kg/m², with normal body weight in 47.89% of patients. Despite this, central obesity indices indicated fat redistribution, with elevated ABSI (>0.085) in 42.3% of patients.ABSI was associated with age (R = 0.389; p < 0.001) and pre-transplant dialysis duration (p = 0.02), and remained significant in multivariable analysis. Age also correlated with other central obesity indices (all p < 0.01). Dietary analysis showed variability in protein intake (1.04 g/kg/day), excess saturated fat, low MUFA/PUFA intake, high sodium, and low potassium, calcium, and vitamin D.

Conclusion: A substantial proportion of kidney transplant recipients exhibit elevated ABSI despite normal BMI, indicating unrecognized central adiposity. ABSI was associated with age and dialysis exposure, suggesting its role as a marker of cumulative metabolic burden. These findings support the use of ABSI as a simple and clinically useful tool for identifying patients at increased metabolic risk. Dietary assessment may provide additional insight into nutritional and functional status in this population.
