Dietary calcium intake and osteoporosis in postmenopausal women living in Sarajevo area
Keywords:dietary calcium intake, osteoporosis
AbstractIntroduction: Osteoporosis is a multifactorial polygenetic disease of which the genetic determinants are modulated by hormonal, environmental and nutritional factors. Identifi cation of the risk factors for osteoporosis
related to nutrition is important in the prevention and treatment of this disease, considering that these factors can be modifi ed. The aim of this study was to examine infl uence of dietary calcium intake on bone
mineral density in postmenopausal women who hadn’t a deficit of estrogen in their menstrual history.
Methods: A total of 100 postmenopausal women living in Sarajevo area, aged 50-65 years, without estrogen deficiency in menstrual history were included in the study. Mineral bone density was measured at the lumbar
spine and proximal femur by Dual–Energy X–ray Absorptiometry using Hologic QDR-4000 scanner. Examination and control group were formed based on mineral bone density values. The women in the examination
group had osteoporosis. The women in the control group had osteopenia or normal mineral bone density. Estimates of daily dietary calcium intake were performed based on a Food Frequency Questionnaire.
Results: The average daily intake of dietary calcium among women who had osteoporosis was 967.32 mg, and in women who hadn’t osteoporosis 1195.12 mg. The difference between two groups was statistically signifi
cant (p<0.001). There was registered signifi cant correlation between intake of dietary calcium and mineral bone density in examination (p<0.01) and in control group (p<0.01).
Conclusion: The results of this study have shown that adequate daily intake of dietary calcium in postmenopausal women aged 50-65 years living in Sarajevo area, which hadn’t estrogen defi ciency in their menstrual
history (in the group of women without osteoporosis amounted to 1195.12 mg) has a positive impact on bone mineral density.
