Physical Activity May Decrease Risk for Comorbidities in Type 1 Diabetes

(HealthDay News) — For patients with type 1 diabetes, regular physical activity is beneficial for glycemic control, diabetes-linked comorbidities and cardiovascular (CV) risk factors, without apparent increase in adverse events, according to a study published in Diabetes Care.

Barbara Bohn, from the University of Ulm in Germany, and colleagues examined the correlation between physical activity and glycemic control or CV risk in a cohort of 18,028 adults with type 1 diabetes. Participants were classified according to self-reported frequency of physical activity (inactive, one to two times per week and more than two times per week).

Results indicated that physical activity was inversely correlated with HbA1c, diabetic ketoacidosis, BMI and dyslipidemia (all P<.0001), as well as hypertension (P=.0150). 

In addition, physical activity was inversely associated with retinopathy and microalbuminuria (both P<.0001). 

No difference was seen between the physical activity groups in terms of severe hypoglycemia (assistance required) (P=.8989); there was an inverse correlation for physical activity with severe hypoglycemia with coma (P<.0001).

“In conclusion, being physically active is associated with reduced cardiovascular risk and better glycemic control without an increase in adverse effects,” the researchers wrote. “Therefore, [physical activity] should be promoted in patients with type 1 diabetes.”
