Adolescent pregnancy occurs in all societies, but the level of teenage pregnancy and childbearing varies from country to country. A cross-country analysis of birth and abortion measures is valuable for understanding trends, for identifying countries that are exceptional and for seeing where further in-depth studies are needed to understand observed patterns.
Birth, abortion and population data were obtained from various sources, such as national vital statistics reports, official statistics, published national and international sources, and government statistical offices. Trend data on adolescent birthrates were compiled for 46 countries over the period 1970-1995. Abortion rates for a recent year were available for 33 of the 46 countries, and data on trends in abortion rates could be gathered for 25 of the 46 countries.
The level of adolescent pregnancy varies by a factor of almost 10 across the developed countries, from a very low rate in the Netherlands (12 pregnancies per 1,000 adolescents per year) to an extremely high rate in the Russian Federation (more than 100 per 1,000). Japan and most western European countries have very low or low pregnancy rates (under 40 per 1,000); moderate rates (40-69 per 1,000) occur in Australia, Canada, New Zealand and a number of European countries. A group of five countries--Belarus, Bulgaria, Romania, the Russian Federation and the United States--have pregnancy rates of 70 or more per 1,000. The adolescent birthrate has declined in the majority of industrialized countries over the past 25 years, and in some cases has been more than halved. Similarly, pregnancy rates in 12 of the 18 countries with accurate abortion reporting showed declines. Decreases in the adolescent abortion rate, however, were less prevalent.
The trend toward lower adolescent birthrates and pregnancy rates over the past 25 years is widespread and is occurring across the industrialized world, suggesting that the reasons for this general trend are broader than factors limited to any one country: increased importance of education, increased motivation of young people to achieve higher levels of education and training, and greater centrality of goals other than motherhood and family formation for young women.
青少年怀孕现象在所有社会中都存在,但青少年怀孕和生育的水平因国家而异。对出生和堕胎措施进行跨国分析,对于了解趋势、识别异常国家以及确定哪些地方需要进一步深入研究以理解观察到的模式很有价值。
出生、堕胎和人口数据来自各种来源,如国家生命统计报告、官方统计数据、已发表的国家和国际资料以及政府统计办公室。编制了46个国家在1970 - 1995年期间青少年出生率的趋势数据。46个国家中有33个国家提供了最近一年的堕胎率数据,46个国家中有25个国家可收集到堕胎率趋势数据。
发达国家青少年怀孕水平相差近10倍,从荷兰的极低水平(每年每1000名青少年中有12例怀孕)到俄罗斯联邦的极高水平(每1000名青少年中超过100例)。日本和大多数西欧国家的怀孕率非常低或较低(每1000名青少年中低于40例);澳大利亚、加拿大、新西兰和一些欧洲国家的怀孕率处于中等水平(每1000名青少年中40 - 69例)。白俄罗斯、保加利亚、罗马尼亚、俄罗斯联邦和美国这五个国家的怀孕率为每1000名青少年中70例或更多。在过去25年中,大多数工业化国家的青少年出生率有所下降,在某些情况下下降幅度超过一半。同样,在18个有准确堕胎报告的国家中,有12个国家的怀孕率下降。然而,青少年堕胎率下降的情况不太普遍。
在过去25年中,青少年出生率和怀孕率下降的趋势普遍存在,且在工业化世界中都在发生,这表明导致这一总体趋势的原因比局限于任何一个国家的因素更为广泛:教育的重要性增加、年轻人追求更高水平教育和培训的动力增强,以及对年轻女性而言,成为母亲和组建家庭以外的目标变得更加重要。
