TOPLINE
, with the association, though weaker, still significant among those who do not develop type 2 diabetes or hypertension, in a large cohort study.
METHODOLOGY
- The study included data on 593,660 adolescents aged 16-20, born after January 1, 1975, who had medical assessments as part of mandatory military service in Israel.
- The mean age at study entry was 17.2 and 54.5% were male.
- Early CKD was defined as stage 1 to 2 CKD with moderately or severely increased albuminuria, with an estimated glomerular filtration rate of 60 mL/min/1.73 m2 or higher.
- The study excluded those with kidney pathology, albuminuria, hypertension, dysglycemia, or missing blood pressure or BMI data.
- Participants were followed up until early CKD onset, death, the last day insured, or August 23, 2020.
TAKEAWAY
- With a mean follow-up of 13.4 years, 1963 adolescents (0.3%) overall developed early chronic kidney disease. Among males, an increased risk of developing CKD was observed with a high-normal BMI in adolescence (hazard ratio [HR], 1.8); with overweight BMI (HR, 4.0); with mild obesity (HR, 6.7); and severe obesity (HR, 9.4).
- Among females, the increased risk was also observed with high-normal BMI (HR 1.4); overweight (HR, 2.3); mild obesity (HR, 2.7); and severe obesity (HR, 4.3).
- In excluding those who developed diabetes or hypertension, the overall rate of early CKD in the cohort was 0.2%.
- For males without diabetes or hypertension, the adjusted HR for early CKD with high-normal weight was 1.2; for overweight, HR 1.6; for mild obesity, HR 2.2; and for severe obesity, HR 2.7.
- For females without diabetes or hypertension, the corresponding increased risk for early CKD was HR 1.2 for high-normal BMI; HR 1.8 for overweight; 1.5 for mild obesity and 2.3 for severe obesity.
IN PRACTICE
“These findings suggest that adolescent obesity is a major risk factor for early CKD in young adulthood; this underscores the importance of mitigating adolescent obesity rates and managing risk factors for kidney disease in adolescents with high BMI,” the authors report.
“The association was evident even in persons with high-normal BMI in adolescence, was more pronounced in men, and appeared before the age of 30 years,” they say.
“Given the increasing obesity rates among adolescents, our findings are a harbinger of the potentially preventable increasing burden of CKD and subsequent cardiovascular disease.”

The study was conducted by first author Avishai M. Tsur, MD, of the Israel Defense Forces, Medical Corps, Tel Hashomer, Ramat Gan, Israel and Department of Military Medicine, Hebrew University of Jerusalem Faculty of Medicine, Jerusalem, Israel, and colleagues. The study was published online in JAMA Pediatrics.
LIMITATIONS
The study lacked longitudinal data on clinical and lifestyle factors, including stress, diet and physical activity. While adolescents were screened using urine dipstick, a lack of serum creatinine measurements could have missed some adolescents with reduced eGFR at the study entry. The generalizability of the results is limited by the lack of people from West Africa and East Asia in the study population.
DISCLOSURES
Coauthor Josef Coresh, MD, reported receiving grants from the National Institutes of Health outside the submitted work. No other disclosures were reported.
