Two Paths to Diabetes-Related CVD
Both obesity and physical activity are recognized risks for type 2 diabetes
and its cardiovascular disease (CVD) fellow traveler, but does one carry more
weight, so to speak, in the development of morbidity? According to an analysis
of national data reported in the July issue of Diabetes Care,
physical inactivity and obesity are independent risk factors for diabetes and
related cardiovascular comorbidities.
Patrick W. Sullivan, PhD, of Colorado Health Sciences Center, and
colleagues reviewed information from the Medical Expenditure Panel Survey
(MEPS), a comprehensive survey of 68,500 adults conducted 2000–2002.
MEPS collected detailed information about sociodemographic traits and health
conditions, and physical characteristics such as height and weight.
Analysis revealed that the risk of developing diabetes and related CVD risk
factors increased with body mass index (BMI) regardless of the level of
physical activity. Those same risks also increased with physical inactivity
regardless of BMI.
Compared with a normal-weight physically active adult, the risk of diabetes
and related comorbidities was 1.5 times higher in a normal-weight inactive
adult and 1.65 times higher in an overweight inactive adult. The risk of
diabetes and hypertension was 1.7 times greater for a normal-weight inactive
adult and 1.8 times greater for an overweight inactive adult, compared with a
normal-weight physically active adult.
"Both physical activity and obesity seem to be strongly and
independently associated with diabetes and diabetes-related
comorbidities," the group concludes.
