Two Years Longer, to Be Exact

Sit Less; Live Longer

Reducing the time Americans spend sitting to fewer than 3 hours/day would increase life expectancy by 2 years, finds a Pennington Biomed. Res. Ctr. study helmed by Peter Katzmarzyk. The research also indicates that reducing the time spent watching TV to fewer than 2 hours would increase life expectancy by 1.4 years. US adults spend about 5 hours/day sitting. The study highlights "sedentary behavior as an important risk factor, similar to smoking and obesity," says Katzmarzyk who analyzed data on 167,000 adults. It looked at the link between sitting and the risk of dying from any cause over the next 4-14 years. His conclusion: about 27% of deaths could be attributed to sitting; 19% to television watching habits. The study is one among a growing number that suggests sitting may be deadly.

Lower BMI Reduces Death Risk

Ideal BMI Identified by NIH: 22.5 to 24.9

"The ideal woman's BMI from the standpoint of attracting men is 20.8. So you need to choose between a longer life, or a better love life."

A body mass index between 20.0 and 24.9 is associated with the lowest risk of death in healthy, non-smoking, non-Hispanic white adults, finds a study from the National Institutes of Health. Researchers pooled data from 19 long-term studies and found that healthy, non-smoking, overweight women were 13 % more likely to die during the study’s follow-up period than were women with a BMI between 22.5 and 24.9. Researchers report a 44 % increase in risk of death for obese women with BMIs of 30 to 34.9. Results were the same for men. Researchers accounted for lifestyle risk factors and came up with similar results, indicating that BMI plays a large role as a risk factor for death. They plan to broaden the range of the study to include other ethnic and racial groups.
