COVID-19 Associated With Increased Diabetes Risk in Youth
Children who have recovered from Covid-19 appear to be at significantly increased risk of developing Type 1 or Type 2 diabetes, researchers at the Centers for Disease Control and Prevention reported on Friday.
A heightened risk of diabetes has already been seen among adults who recovered from Covid, according to some studies. Researchers in Europe have reported an increase in the number of children being diagnosed with Type 1 diabetes since the pandemic started.
But the C.D.C. study is among the first to examine large insurance claim databases in the United States to estimate the prevalence of new diabetes diagnoses in children under age 18 who had Covid or were known to be infected with the coronavirus.
The study used two claim databases from U.S. health plans to look at diabetes diagnoses made in youngsters under 18 over the course of a year or more, starting in March 1, 2020, comparing those who had Covid with those who did not.
The researchers found increases in diabetes in both data sets, though the relative rates were quite different: they found a 2.6-fold increase in new diabetes cases among children in one, and a smaller 30 percent increase in another.
“Even a 30 percent increase is a big increase in risk,” said Sharon Saydah, a researcher at the C.D.C. and lead author of the study. The differences likely result from different ways of classifying children as having Covid, she added.
Dr. Saydah said it was not yet clear whether post-Covid Type 2 diabetes would be a chronic condition in these children, or a transient condition that resolves. (Type 1 diabetes is not reversible.) Most of the children were only followed about four and a half months.
The finding underscores the importance of vaccinating all eligible children against Covid, she added, and using measures like masking and distancing, especially to protect the youngest, who cannot yet be vaccinated.
“It’s really important for clinicians, pediatricians and parents to be aware of the signs and symptoms of diabetes, so they can get their kids diagnosed,” Dr. Saydah said. Increased thirst, frequent urination, unintentional weight loss and fatigue are among the telltale symptoms.
