Youth with T1 Diabetes More Likely to Have AsthmaMonday, October 17, 2011
Children and young adults with diabetes are more likely to have asthma which may affect their ability to manage their diabetes. It may be more challenging for youth with asthma to maintain good glycemic control especially if their asthma is left untreated, according to a new study from the SEARCH Study Group, published online in Pediatrics.
“It is important for parents and health care providers providing care for children and adolescents with type 1 diabetes to recognize and treat symptoms of asthma”
The SEARCH for Diabetes in Youth Study is a large study of youth diagnosed with diabetes before the age of 20 from six clinical centers in California, Colorado, Hawaii, Ohio, South Carolina, and Washington.
Maintaining good blood sugar (glycemic) prevents or delays the onset of diabetic complications in people with diabetes, including children and young adults, but few studies have examined the association between glycemic control and asthma in youth with diabetes. This study examined the relationship between asthma and glycemic control in a racially and ethnically diverse group of 1,994 children and young adults aged 3 through 21 years with diabetes from across the United States. Researchers found the prevalence of asthma among all youth with diabetes was 11 percent, slightly higher than the general population. The prevalence of asthma was 10 percent among youth with type 1 diabetes and 16 percent among youth with type 2 diabetes. According to a previous CDC report, nearly 9 percent of all children and young adults in the United States had asthma.
Among youth with type 1 diabetes, those with asthma were more likely to have higher hemoglobin A1C, indicating poorer glycemic control.
“It is important for parents and health care providers providing care for children and adolescents with type 1 diabetes to recognize and treat symptoms of asthma,” said study lead-author Mary Helen Black, PhD, of the Kaiser Permanente Southern California Department of Research & Evaluation.
Researchers also found that a higher percentage of children with asthma and diabetes who are not taking any prescription medications for their asthma were more likely to have poor glycemic control and therefore had a harder time managing their diabetes. Treating asthma with leukotriene modifiers alone or in combination with rescue inhalers was associated with better glycemic control. In fact, 72 percent of these youth receiving these treatments had good glycemic control.
Among children and young adults with type 1 diabetes, those with asthma were also more likely to be overweight or obese. Researchers found 43 percent of youth with asthma were overweight or obese compared to 32 percent of those without asthma. Although these complex conditions have been on the rise since the 1990’s, the relationship between asthma, diabetes, and obesity is not well understood.
