This study reports the descriptive epidemiology of hysterectomy in the Province of Quebec, Canada, from 1981 to 1988. Data on hysterectomies (n = 150,849) among women 15 years and older were obtained from MED-ECHO, a computerized database of hospital discharge summaries. Hysterectomy rates were established, with denominators consisting of the estimated female populations with a uterus. From 1981 to 1988, the age-adjusted rate for hysterectomy declined from 100.4 to 67.4 per 10,000 women with a uterus. Curves representing age-specific rates of hysterectomy revealed a consistent bimodal pattern over time, a first peak occurring in women aged 40 to 44 years, and a second in women aged 65 to 69. Hysterectomy rates for elective conditions such as leiomyoma, endometriosis, disorders of menstruation, and prolapse decreased consistently over time. The proportion of women who had a hysterectomy and simultaneous bilateral oophorectomy declined from 35% in 1981 to 30% in 1988. Despite the substantial decline in the frequency of hysterectomy over the 8-year period, at rates prevailing in 1988, three of ten women would have had a hysterectomy by the age of 60.
本研究报告了1981年至1988年加拿大魁北克省子宫切除术的描述性流行病学情况。15岁及以上女性子宫切除术的数据（n = 150,849）来自MED-ECHO，这是一个医院出院小结的计算机化数据库。确定了子宫切除术的发生率，分母为估计有子宫的女性人口。1981年至1988年，年龄调整后的子宫切除术发生率从每10,000名有子宫的女性100.4例降至67.4例。代表特定年龄子宫切除术发生率的曲线显示，随着时间的推移呈现出一致的双峰模式，第一个高峰出现在40至44岁的女性中，第二个高峰出现在65至69岁的女性中。因子宫肌瘤、子宫内膜异位症、月经紊乱和子宫脱垂等择期病症进行子宫切除术的发生率随时间持续下降。接受子宫切除术并同时进行双侧卵巢切除术的女性比例从1981年的35%降至1988年的30%。尽管在这8年期间子宫切除术的频率大幅下降，但按照1988年的流行率计算，每10名女性中有3名在60岁时会接受子宫切除术。
