Thin Men More Vulnerable to Fractures

September 19, 2008

Men who have low weight in middle age and who reduce their weight, increase the chance of osteoporosis and bone fracture, Norwegian researchers said.

Low weight among middle-age men was related to the risk of osteoporosis three decades later and this risk was significantly affected by weight changes, however, weight increase reduced the risk, Haakon E. Meyer of the Norwegian Institute of Public Health and the University of Oslo said.

The researchers tracked 1,476 men who participated in the Oslo survey in 1972 to 1973 and the Tromso survey in 1974 to 1975 were again studied for, among other things, osteoporosis in the Health Studies in Oslo 2000 to 2001 and Tromso 2001, respectively.

The study showed almost one-third had osteoporosis among the thinnest quarter of men in the 1970s and who later lost weight. In contrast, the quarter of men, who had the highest weight in the 1970s and who hadn’t changed their weight — none had osteoporosis.

Although weight increase and a high weight are beneficial for the skeleton, a stable, healthy weight is still recommended, Meyer said.

The findings are published in The American Journal of Epidemiology.
