To the Editor,

I read the distinguished study by Beladi Mousavi et al[1] published in March-April 2020 issue of the Saudi Journal of Kidney Diseases and Transplantation. On using the World Health Organization (WHO) criteria, the authors nicely studied body weight and body mass index (BMI) before and after kidney transplantation in a pediatric cohort from Iran. They found an increase in BMI and obesity after renal transplantation.[1] The authors mentioned few study limitations, notably small sample size and short duration of follow-up as well as the lack of evaluation of the exact socio-economic standard of the families and the calorie intake and physical activity of the studied patients.[1] I assume that the following methodological limitation might additionally might bring into question the study results. It is noteworthy that there are various BMI standards in the clinical fields, namely Centers for Disease Control standard, WHO standard, and population-specific standard. Since BMI standard is population-dependent and might vary according to the race, lifestyle habits, and dietary pattern on one hand[2] and the observation that the utilization of local BMI standard could assess overweight/obesity more precisely on the other,[3],[4] Iran has launched its own BMI standard in 2016 to be utilized in the researches and clinical practice.[5] I presume that referring to the national BMI standard rather than WHO standard in the study methodology could elucidate an accurate insight on the correlation between kidney transplantation and anthropometric indices of weight and BMI.

Conflict of interest: None declared.
