Ann Inter Med


Recently published in the Annals of Internal Medicine, a new study analyzed the decreases in life span linked to both overweight and obesity in individuals over the age of 40. Over 3,400 participants from the Framingham Heart Study were recruited, aged 30 to 49 years. After measuring for mortality rates, body mass index, and smoking status, the results showed large decreases in life expectancy in those who were overweight or obese. Non-smoking, overweight women lost 3.3 years and men lost 3.1 years. Non-smoking obese men and women lost 7.1 and 5.8 years, respectively. Women who were obese and smokers lost an average of 13.3 years and in the same category, men lost 13.7 years. The authors of this study concluded that these decreases in life expectancy are large due to overweight and obesity and are similar to those of smoking.
