Introduction:

 The COVID-19 pandemic has led to change of lifestyle, restrictions of social relations, physical activities, modifications in eating habits, and psychological distress. The COVID-19 pandemic leads to significant weight gain in the general population, but its impact on pediatric patients after kidney transplantation (KTx) is unknown.

Material and methods:

 We retrospectively evaluated body mass index SD scores (BMI-SDS) between September 2019 and September 2021 in 132 pediatric KTx patients followed up at three German pediatric nephrology centers. The patients were categorized according to age (0-11.9 years vs 12-18 years) and sex (female vs. male) in four groups. Data were assessed by a linear mixed model approach.

Results:

 There was no significant change in BMI-SDS in children (0-11.9 years), irrespectively of  sex (boys -0.11 SDS, p=0.22; girls 0.05 SDS, p=0.49). By contrast, a significant increase in BMI-SDS was noted in both male (0.24 SDS) and female (0.20 SDS) teenagers (each p<0.05). In addition, the proportion of obese teenagers tended to increase from 12% to 19% (p=0.08).

Conclusions:

 The COVID19 pandemic was associated with a significant increase in standardized BMI values in adolescents but not in children after KTx. This may further increase the cardiovascular risk in the former population.
