In the past 50-60 years, desired and actual family size have decreased and contraceptive use has increased, especially in developing countries. Unmet need for modern contraceptives and unintended pregnancy levels remain significant.
Data compiled by the United Nations and information from national surveys of women of reproductive age are used to examine trends.
Oral contraceptives and condoms have been predominant methods in developed countries; sterilization has been the most common in Latin America and the Caribbean and Asia; hormonal methods, in Africa. Some 222 million women in developing countries have unmet need for modern contraceptives, resulting in 2012 in an estimated 54 million unintended pregnancies and 79,000 maternal deaths more than if they used modern methods.
Improvements are needed in contraceptive information and services as well as in contraceptive methods themselves to increase couples' success in achieving their desired timing and number of children.
在过去的 50-60 年里,人们期望的家庭规模和实际的家庭规模都有所缩小,避孕措施的使用有所增加,尤其是在发展中国家。对现代避孕药具的需求未得到满足以及意外怀孕的比例仍然很高。
利用联合国汇编的数据和来自育龄妇女的国家调查信息来考察趋势。
口服避孕药和避孕套在发达国家一直是主要方法;在拉丁美洲和加勒比地区以及亚洲,绝育是最常见的方法;在非洲,激素方法较为常见。发展中国家约有 2.22 亿妇女对现代避孕药具的需求未得到满足,这导致 2012 年约有 5400 万例意外怀孕和 7.9 万例孕产妇死亡,如果使用现代方法,这些数字本可以减少。
需要改进避孕信息和服务以及避孕方法本身,以提高夫妇实现其期望的生育时间和生育数量的成功率。
