Özet

This study investigated the effect of the number of pregnancies on bone mineral density (BMD) in 320 post-menopausal women aged between 49 and 64 years. Cases were selected from people with similar lifestyles and stratified into five groups according to the number of pregnancies. Each group was divided into two subgroups according to the duration of the menopause (3 - 5 years versus 6 - 10 years). Lumbar (L2 - L4) and femoral neck BMD were measured by dual-energy X-ray absorptiometry and T-score values were used in the statistical evaluation. No significant difference was found between the number of pregnancies and BMD within each group based on the same menopause duration, but a significant correlation was found in most groups based on menopause duration: T-scores decreased as menopause duration increased. Changes in BMD are likely to be related to menopause duration, rather than the number of pregnancies.
