Underweight women who had never smoked with a BMI of less than 18.5 were 1.5 times more likely to die -- 151 percent more likely -- during a 10-year follow-up than normal weight women who had never smoked with a BMI of 23.5 to 25, although there was more than a 5 percent chance that the difference was due to random chance, according to a new study from the US's National Institute on Aging in Bethesda, Maryland, USA.

To put this another way, women who were normal weight with a BMI of 23.5 to 25, were 34 percent less likely to die than lean women with a BMI of 18.5-23.5. Subjects

Subjects: 149,502 men and 88,184 women, aged 51- to 72-years-old

The study analyzed data over a 10-year follow-up, from 1996 to 2006, on 149,502 men and 88,184 women, aged 51- to 72-years-old, who were participating in the National Institutes of Health–AARP Diet and Health Study.
