Abstract
As one phase of a comprehensive population study of women, bone density was determined
in the third lumbar vertebra by dual photon absorptiometric technique. The method
involves the use of two radionuclides, which both emit gamma radiation but with different
energies (241 Am with 59.6 keV and 137Cs with 662 keV).
Women in three age strata were studied: 46, 54 and 62 yr. All women aged 46 were still
menstruating, while the age strata 54 and 62 were subdivided into two groups: those
who still menstruated or had been postmenopausal for a short time and those who had
been postmenopausal for many years. The bone mineral content was higher in premenopausal
or recently postmenopausal 54-yr-old women than in women of the same age who had been
postmenopausal for a long time (P < 0.01). A similar trend was found for women aged 62 (P < 0.10). The differences could not be explained by differences in other factors studied,
such as body weight, body height, smoking habits or physical activity. No significant
differences were found when women with similar menopausal status in different age
groups were compared.
