Influence of osteoporosis risk faktors on bone mass loss in postmenopausal women

Introduction: Estrogen deficiency plays a critical role in the development of osteoporosis. However, some other factors may contribute to bone loss as well. Aim: To show presence of osteoporosis risk factors and to examine its influence on bone mass loss in women with normal menstrual history.Methods: The study included 30 postmenopausal women, ages from 50 to 65 with osteoporosis who entered into menopause before the age of 45, and 30 postmenopausal women, ages from 50 to 65 with osteoporosis who had normal menstrual history. Presence of risk factors has been calculated for both groups and statistical significance of differences between two groups presented.Results: In the group with normal menstrual history 33.33% women had low level of physical activities, 56.66% suffered from insuficient intake of calcium, 63.33% of women were active smokers. Body mass index bellow 19 had 6.66% women, insuficient exposure to the sun was registered in 60%, and 23.33% women were either taking medicaments or had diseases that could cause osteoporosis. Statistical significance of differencies in presence of certain risk factors between two groups was registered for : insuficient daily intake of calcium (p <0.001), insuficient exposure to the sun (p<0.001), and smoking (p <0.001).Conclusion: Results of the study indicate high presence of osteoporosis risk factors in women with normal menstrual history and indicate influence of certain factors (calcium, sun exposure, smoking) on occurence ofosteoporosis in this group
