Effect of starting age of physical activity on bone mass in the dominant arm of tennis and squash players

Article Abstract:

Starting tennis or squash training near the age of menarche may increase the bone mineral mass in the playing arm of women. Menarche is the start of monthly menstruation, usually between the ages of 9 and 17. Researchers measured the effect of age on bone mineral content among 105 female national-level squash and tennis players and 50 female controls. All women players had higher bone mineral content in their dominant arms compared to controls. However, the mineral content was twice as high in those who had started playing at or before menarche. With a later onset of playing, group averages of bone mineral content dropped accordingly. The least change in bone mass was noticeable in those who started a racket game more than 15 years after menarche.

Increasing number and incidence of fall-induced severe head injuries in older adults: nationwide statistics in Finland in 1970-95 and prediction for the future

Article Abstract:

Increases in the number and incidence of fall-induced severe head injuries in older adults in Finland are discussed based on nationwide statistics, 1970-95. A randomly selected reference group aged 30-39 years was studied as well. The prediction is made that with the at-risk population increasing, there will be many more such injuries and they will be more difficult to treat because the mean age of patients presenting is going up. The rate of increase cannot be explained entirely by demographic changes and vigorous preventive measures should be in place. The injuries are devastating and represent an increasing burden.

Epidemiology of osteoporotic ankle fractures in elderly persons in Finland

Article Abstract:

The frequency of ankle fractures associated with osteoporosis appears to be increasing in Finland. Osteoporosis-associated fractures are those that occur later in life or after minimal stress. Researchers tracked the frequency of osteoporosis-associated ankle fractures in Finland during various years between 1970 and 1994. The incidence of these fractures per 100,000 persons older than 60 years of age increased from 57 in 1970 to 130 in 1994. Both male and female populations showed significant increases in osteoporosis-associated ankle fractures.
