چکیده

مقدمه: یائسگی طبیعی عبارت است از قطع عادت ماهیانه در خانم‌ها که به دلیل توقف فعالیت فولیکولار تخمدان در طی 12 ماه متوالی، بدون هیچگونه علت پاتولوژیکی و فیزیولوژیکی روی می‌دهد و به پایان‌یافتن دوران باروری در زن می‌انجامد. یائسگی، بر کیفیت زندگی زنان تأثیر می‌گذارد و می‌تواند موجب بروز مشکلاتی همچون پوکی استخوان و بیماری‌های قلبی نیز بشود. در این مطالعه، الگوی سنی یائسگی طبیعی درزنان شهرستان شاهرود مورد بررسی قرار گرفته است.
روش کار: در این مطالعه مقطعی، 1392 خانم 30 ساله و بالاتر ساکن شهر و روستاهای شهرستان شاهرود طی سال 1385 به روش خوشه‌ای، انتخاب و به روش مصاحبه، پرسشنامه حاوی اطلاعات لازم برایشان تکمیل شد. از آنجا که هدف این بررسی، برآورد الگوی سن یائسگی طبیعی بود، لذا موارد غیر طبیعی ناشی از جراحی کنار گذاشته شدند و در نهایت، 1338 خانم، مورد بررسی قرار گرفته و الگوی سن یائسگی آنان با استفاده از شیوع یائسگی در هر گروه سنی، برآورد شد.
نتایج: میانگین±انحراف معیار و میانه سن یائسگی برای شهرستان شاهرود به ترتیب، 7/5±2/53 و 7/50 سال برآورد شد. یائسگی از سن 30 تا تقریباً 42 سالگی به آرامی افزایش می‌یافت؛ اما پس از آن، تا سن تقریباً 54 سالگی سرعت آن رو به افزایش گذاشته و سپس به آرامی رو به کاهش می‌گذاشت.
نتیجه‌گیری: یافته‌ها نشان می‌دهند میانگین سن یائسگی شهرستان شاهرود در مقایسه با سایر نقاط کشور، بالاتر می‌باشد. برای ارزیابی دقیقتر این امر، انجام مطالعات با متدولوژی مناسب، در نقاط مختلف کشور ضروری است.

چکیده [English]

Introduction: Menopause is defined as the permanent cessation of menstruation resulting from the loss of ovarian follicular activity which is recognized to have occurred after 12 consecutive months of amenorrhea, for which there is no other obvious pathological or physiological cause. It leads to changes in the quality of life, osteoporosis and heart diseases in affected women. In this paper the pattern of age of natural menopause in Shahrood (in Semnan province, Iran) was studied.
 
Methods: This cross-sectional study enrolled 1392 women who were 30 years old or older. They were randomly selected using a cluster sampling method and interviewed to fill out a questionnaire including required data. An exclusion criterion was the presence of abnormal menopause due to surgery. Finally 1338 women remained in the study and the pattern of the age of menopause was estimated for them calculating the prevalence of menopause in each age group.
 
Results: Mean and median ages at natural menopause were 53.2 5.7 and 50.7 years respectively. The prevalence of menopause was low from age 30 to 42, but it showed a steady increase to the age of 54 years old. The prevalence of natural menopause slowed down after the age of 54 in our study.
 
Conclusion: Findings of our study showed that mean age at natural menopause in Shahrood is higher than other regions of Iran. However, careful estimation of age at natural menopause needs further studies using appropriate methodology in other regions of Iran.
