Texas Finds Cardiorespiratory Fitness Reduces Disease Risk among Smokers

Cardiorespiratory fitness is associated with reduced metabolic syndrome risk among smokers, according to researchers from The University of Texas Health Science Center at Houston (UTHealth) School of Public Health. The study was published today in the American Journal of Preventive Medicine.

Smoking is estimated to cause 443,000 deaths each year in the United States, primarily from cancer, cardiovascular diseases, and respiratory disease, according to the Centers for Disease Control and Prevention.

“We know that greater cardiorespiratory fitness reduces the risk of certain diseases, but we wanted to evaluate the effects of fitness on cardiometabolic risk factors specifically among smokers. Study findings indicate that there is an inverse relationship between cardiorespiratory fitness and cardiometabolic risk among adult smokers” said Dr. Darla Kendzor, assistant professor in the department of health promotion and Behavioral Sciences at UTHealth School of Public Health Dallas Regional Campus.

Metabolic syndrome is the clustering of at least three of the following five risk factors: elevated fasting glucose, excess waist circumference, elevated blood pressure, elevated triglycerides and abnormal HDL cholesterol. The presence of metabolic syndrome has been found to increase the risk for cardiovascular disease and type 2 diabetes.

In the study, the risk for metabolic syndrome was reduced for smokers who were either highly or moderately fit. Smokers with the highest level of fitness reduced their risk for metabolic syndrome by 48 percent compared to those in the low fitness category. The moderate fitness group had a 27 percent reduced risk for metabolic syndrome in comparison to those who had low fitness levels.
