The prevalence of pediatric diabetes (types 1 and 2) increased among commercially insured young people in the U.S. from 2002 to 2013, with the highest prevalence among youths ages 12 to 17, a new study led by Boston University School of Public Health (BUSPH) researchers shows.
The study, published in the journal Diabetes Care, found that prevalence of pediatric diabetes increased over the study period, while the prevalence of diabetes nephropathy, or kidney disease, also increased. Although type 1 diabetes — an autoimmune disease — accounts for a majority of childhood and adolescent diabetes, type 2 diabetes has become more common with the increasing rate of childhood obesity, the authors noted.
The research team tracked diabetes prevalence in a large commercial claims database, identifying more than 96,000 pediatric patients with diabetes and 3,161 with diabetic nephropathy from 2002 to 2013.
The annual prevalence of diabetes in the whole pediatric population increased from 1.86 youths per 1,000, to 2.82 per 1,000 (an average 3.7 percent increase per year). Type 1 diabetes rose from 1.48 per 1,000 children to 2.32 per 1,000, while type 2 rose from 0.38 per 1,000 to 0.67 per 1,000 from 2002 to 2006, then declined slightly from 0.56 to 0.49 per 1,000 thereafter.
During the same time period, the prevalence of pediatric patients with diabetic kidney disease rose from 1.16 percent of all pediatric diabetes cases to 3.44 percent.
Study co-author Dr. Susan Jick, director of the Boston Collaborative Drug Surveillance Program at BUSPH and a professor of epidemiology, said the slight decline in type 2 diabetes in the later years of the study was encouraging.
“Diabetes is associated with significant morbidity, so it is very good that the prevalence is going down. We hope that it continues to go down,” she said.
