@entity1 @entity16732
69.1% of @entity1 of childbearing age in Qinzhou City, China, are currently using IUDs. A sample survey of 474 @entity1 had shown that the level of failure of this contraceptive method was undesirably high. 26.16% of the survey respondents experienced @entity16732 expulsion. The highest was among @entity1 in the 25-29 age group (29.15%). It was believed that reported expulsions were most probably user-initiated removals because most @entity1 in this age group had already had a @entity1 , and they would want to have another @entity1 , especially if the 1st @entity1 was a @entity1 . The study also showed that the expulsion rate was higher among those @entity1 who had had and @entity16732 inserted at a young age. The expulsion rate of @entity1 who had the insertion when they were 20-24 was 1.59 times higher than those in the 25-29 age group, and 2.02 times higher than those in 30-35 age group. This suggested that the uterine cavities of younger @entity1 with low parity might be more sensitive to foreign objects. Analysis by types of institution where @entity16732 insertion was provided showed that expulsion was over 3 times higher among those who had had an @entity16732 inserted in village clinics than in hospitals at county level and above. This suggested that the skill of service providers and medical facilities may be correlated with @entity16732 expulsion. Village rural doctors usually received less training and may have limited supplies of different sizes of IUDs which contributed to higher rates of @entity16732 expulsion of their @entity1 . A number of recommendations are made for improving the effectiveness of the @entity16732 . It is necessary to strengthen population education among @entity1 to increase their commitment to fertility control. Service providers should receive proper training before they can perform @entity16732 insertions. Medical professionals having good attitudes and outstanding performance should be rewarded. Those who helped remove IUDs illegally should be subjected to discipline or legal procedures. Regular examination after @entity16732 insertion should be emphasized to ensure its effectiveness.
