OBJECTIVES
Estimation of mean and median age at menopause among Iranian women using a cumulative distribution by region.
METHODS
The number of 8194 women aged between 30 and 65+ who enrolled in National Health Survey in the year 2000 in Iran through cluster sampling were studied and according to their age and the onset of their menopause (12 month consecutive menstrual cessation), the pattern of age at natural menopause has been described using a cumulative distribution.
RESULTS
The median age of menopause has been calculated to be 49.9, 49.2, and 49.6 years in urban, rural, and total population, respectively. While the mean age at menopause in total population was 50.4 years (S.D.=4.3). As it has been shown, the median age of menopause in rural areas (49.2) is earlier than urban areas (49.9). This difference is statistically significant (95% CI: 1.00066, 1.03363).
CONCLUSION
There are different factors influencing age at natural menopause but there are not certain and homogenous results about those factors in different studies. Therefore, it is obvious that exploring these factors in different regions in Iran merit to be done.
目的
利用按地区划分的累积分布来估算伊朗女性绝经的平均年龄和中位数年龄。
方法
对2000年通过整群抽样参与伊朗全国健康调查的8194名年龄在30至65岁以上的女性进行研究，根据她们的年龄和绝经开始时间（连续12个月停经），使用累积分布描述自然绝经年龄模式。
结果
城市、农村和总人口中绝经的中位数年龄分别计算为49.9岁、49.2岁和49.6岁。而总人口中绝经的平均年龄为50.4岁（标准差=4.3）。如图所示，农村地区绝经的中位数年龄（49.2岁）早于城市地区（49.9岁）。这种差异具有统计学意义（95%置信区间：1.00066，1.03363）。
结论
有不同因素影响自然绝经年龄，但不同研究中关于这些因素的结果并不确定且不一致。因此，显然有必要在伊朗不同地区探索这些因素。
