Objective To investigate the current age of natural menopause among women in Beijing and analyze the related factors that influence the age of menopause in women. Methods In 1999, 18 districts (counties) in the Beijing area took 10 sample groups to measure the percentage of stratified clusters, and surveyed 40 to 65-year-old perimenopausal women in the sample group. The average age of natural menopause was 4 8.4 years old. The average age of menopause in the 4 0 to 4 4 groups was 4 7.19 years, and the average age of menopause in the 5 5 to 6 5 years group was 4 9.2 1 years. The average age of spontaneous menopause between the two groups in the recent 20 years was significantly earlier than 2.02 years ( P <0. 0 1). Conclusions Women of childbearing age have the first gestational age and the age at first birth, the decrease in the number of births, and the shortening of the lactation period, leading to a significant increase in the average age of natural menopause in the past 20 years.
