Physical activity and bone mineral density in postmenopausal women without estrogen deficiency in menstrual history
AbstractIntroduction: The estrogen defi ciency after menopause leads to accelerated loss of bone mass. The aim of this study was to examine influence of physical activity on bone mineral density in postmenopausal women who hadn’t a deficit of estrogen in their menstrual history.
Methods: This prospective study included 100 postmenopausal women, ages between 50 and 65, living in Sarajevo area without estrogen deficiency in menstrual history. The women in the examination group had osteoporosis. The women in the control group had osteopenia or normal mineral bone density. Mineral bone density was measured at the lumbar spine and proximal femur by Dual–Energy X–ray Absorptiometry using Hologic QDR-4000 scanner. To assess level of physical activity an International Physical Activity Questionnaire - Long Form was used.
Results: In the examination group of women who had no history of menstrual estrogen deficit, level of physical activity was low in 52.00% female, and in 48.00% women level of physical activity was moderate. In the control group of women who had no history of menstrual estrogen defi cit in 10.00% female level of physical activity was low, and in 90.00% female level of physical activity was moderate. The difference in levels of physical activity between the two groups was statistically significant, X2 test = 20.6, p <0.005.
Conclusion: Results of this study suggest that moderate physical activity has positive impact on bone mineral density in postmenopausal women without estrogen defi ciency in menstrual history and has the potential to reduce rapid bone loss after menopause.
