Adults who are exposed to secondhand smoke have higher rates of obesity and Type 2 diabetes than do nonsmokers without environmental exposure to tobacco smoke, a new study shows. The results will be presented at The Endocrine Society’s 94th Annual Meeting in Houston.
“More effort needs to be made to reduce exposure of individuals to second hand smoke,” said study co-author Theodore C. Friedman, MD, PhD, chairman of the Department of Internal Medicine at Charles R. Drew University, Los Angeles.
Studies have shown an association between cigarette smoking and an increased rate of Type 2 diabetes despite the fact that most smokers are leaner than nonsmokers and obesity is a risk factor for Type 2 diabetes. Although some studies have suggested a relationship between Type 2 diabetes and passive, or secondhand, smoking, Friedman said these studies have not verified exposure to secondhand smoke through serum (blood) levels of cotinine. Cotinine is a metabolite of nicotine, and serum cotinine measures a person’s exposure to tobacco smoke. Read more
