چکیده

مقدمه: وضعیت سلامت زنان پس از یائسگی به دلیل کاهش سریع سطح استروژن به شدت تغییر می کند. انجام فعالیت های پیشگیرانه مناسب می‌تواند باعث سازگاری و سطح سلامت بالاتر در این دوره شود. مطالعه حاضر با هدف مقایسه تراکم و محتوای مواد معدنی و همچنین میزان شیوع استئوپنی و استئوپروز مهره‌های کمری در زنان یائسه فعال و غیر فعال انجام شد.
روش کار: این مطالعه در سال1390 بر روی 12 زن یائسه فعال و 12 زن یائسه غیرفعال 58-50 ساله انجام شد. گروه فعال تجربه حداقل 3 سال برنامه پیاده روی (3 جلسه در هفته و هر جلسه یک ساعت) داشتند، در حالی که گروه غیر فعال هیچگونه برنامه ورزشی مشخصی نداشتند. تراکم و محتوای مواد معدنی و میزان شیوع استئوپنی و استئوپروز استخوان ران به وسیله دستگاه DEXA اندازه‌گیری شد. تجزیه و تحلیل داده ها با استفاده از نرم‌افزار آماری SPSS (نسخه 16) و آزمون های کولموگروف- اسمیرنوف و تی مستقل انجام شد. میزان p کمتر از 05/0 معنی دار در نظر گرفته شد.
یافته ها:تراکم مواد معدنی مهره های کمری و مقادیر Tscore زنان یائسه فعال در تمامی قسمت های اندازه گیری شده بیشتر از زنان غیر فعال بود و تفاوت بین دو گروه از نظر آماری معنی دار بود (002/0=p). همچنین محتوای مواد معدنی استخوان زنان فعال (002/0=p) به جز مهره اول و دوم کمر و مقادیر Zscore به جز مهره اول تا چهارم و کل کمر از زنان غیرفعال بالاتر بود و این اختلاف از نظر آماری معنی دار بود. میزان شیوع استئوپنی و استئوپروز نیز در زنان یائسه فعال کمتر از همتایان غیر فعال بود.
نتیجه گیری: شرکت در فعالیت‌های بدنی ساده نظیر پیاده‌روی می تواند منجر به افزایش تراکم و محتوای موادمعدنی در مهره‌های کمری و در نتیجه کاهش میزان شیوع استئوپورز و استئوپنی و همچنین کاهش خطر شکستگی‌های استخوانی در زنان یائسه شود.

چکیده [English]

Introduction: Background and purpose: The female health status after menopause drastically changes due to rapid decrease in estrogen levels. Appropriate preventive measures can result in improved health and adjustment in this period. In this study, Bone Mineral Density (BMD) and Bone Mineral Content (BMC) of the lumbar spine, as well as the prevalence of spinal osteopenia and osteoporosis, were compared in active and inactive postmenopausal women.
Methods: This study was performed in 2011 on 12 active and 12 inactive postmenopausal women aged 50–58. The active group had walking experience of  at least 3 years (three sessions per week, one hour per session) while the inactive group did not have any apparent physical activity. BMD and BMC and the prevalence of femoral osteopenia and osteoporosis were measured using the DEXA device. The data were analyzed by the Kolmogorov-Smirnov test and independent t-test, using the SPSS software (ver. 16). The values of P < 0.05 were considered significant.
Findings: BMD of lumbar vertebrae and the T-score values of postmenopausal women were higher in all measurements in active women, and there was a statistically significant difference between the two groups (P=0.002). BMC of the lumbar spine of active women was higher (P=0.002) compared with the inactive women, except in the first and second vertebrae. Furthermore, the values of the Z-score of the active women were higher compared with the inactive women except in the first to fourth vertebrae and total lumbar spine and the difference was statistically significant. Osteopenia and osteoporosis were less prevalent in active postmenopausal women compared to the inactive women.
Discussion : Participating in simple physical activities such as walking can increase BMD and BMC of the lumbar spine and decrease the prevalence of osteopenia and osteoporosis as well as the risk of bone fractures in postmenopausal women.
