Incidence of Type 1 Diabetes in Children Nearly Doubled in Some Populations
Terri Lipman presented at the ADA’s 74th Scientific Sessions on her ongoing analysis of the pediatric population in Philadelphia, and showed that the rate of type 1 diabetes is increasing.

Terri Lipman, PhD, CRNP, FAAN, Miriam Stirl Endowed Term Professor of Nutrition, Professor of Nursing of Children, and Assistant Dean for Community Engagement, recently presented at the American Diabetes Association’s 74th Scientific Sessions from June 13-17, 2014 in San Francisco. Her presentation centered on her ongoing analysis of the pediatric population in Philadelphia, and showed that the rate of type 1 diabetes is increasing, with some populations and age groups increasing greatly since the first cohort from 1985 to 1989.

Lipman and colleagues analyzed in-patient and out-patient charts from subjects at Philadelphia hospitals who met WHO registry criteria: those with newly diagnosed diabetes, aged 0 to 14 years, residing in Philadelphia at the time of diagnosis and diagnosed between Jan. 1, 2005, to Dec. 31, 2009.

“Research on the risk factors associated with the significant rise, particularly in young children, must continue. And, most importantly, [increasing awareness among] primary care providers and parents of the rising incidence of type 1 diabetes in young children is crucial,” said Lipman.

The increase in type 1 diabetes was demonstrated in all racial/ethnic groups. The greatest overall racial/ethnic increase was shown in white children with a rate of type 1 diabetes that has increased by 69% since 1985 (P<.001). There was a 33% increase in the rates for blacks and a 10% increase in the rate for Hispanics over the 25 years of study, Lipman said.

“The incidence of type 1 diabetes has increased in all age groups. Most notably, the incidence of type 1 diabetes has more than doubled in the 0- to 4-year age group over the past 20 years (P<.001) and the incidence continues to rise,” she said.

Dr. Lipman’s research stems from issues arising from her clinical practice. Her major areas of research are the epidemiology of diabetes in children, pediatric growth disorders, and racial disparities in children with endocrine disorders. Since 1990, Dr. Lipman has maintained the Philadelphia Pediatric Diabetes Registry - a participating center in the World Health Organization Multinational Project for Childhood Diabetes program, a consortium of 150 centers in 70 countries. It is the only such US registry still active.
