400 women in continuous care of a family planning clinic were examined for gallbladder stones by standard ultrasound technique. Gallstones (GS) are found infrequently in nulliparous women (3.1 percent). The prevalence of GS increases with number of births and with age: 11 percent of female under 25 years of age, who have ever born, have GS; women aged 45 years and older who have born two or more children have GS in 35 percent. Duration of use of HC increases with rising age and with number of births. There is no regular relationship between duration of use of HC or total dose respectively and prevalence of gallbladder stones.
Intake of HC has no or only a marginal influence on prevalence of gallbladder stones.
采用标准超声技术对一家计划生育诊所持续护理的400名女性进行胆囊结石检查。未生育女性中胆囊结石（GS）的检出率较低（3.1%）。GS的患病率随生育次数和年龄增加而升高：曾生育的25岁以下女性中，11%患有GS；45岁及以上且生育两个或更多子女的女性中，35%患有GS。激素避孕药（HC）的使用时长随年龄和生育次数增加而增加。HC的使用时长或总剂量与胆囊结石患病率之间均无规律关系。
摄入HC对胆囊结石患病率无影响或仅有轻微影响。
