Adolescent pregnancy has been associated with the early childbearing experience of the mothers of adolescents, and young people's education level is believed to be an important factor in this phenomenon.
In 2002, a representative household survey collected data from 3,050 young men and women aged 20-24 in three Brazilian cities. The main measures were mother's age at first birth, daughter's age at first pregnancy and son's age when he first impregnated a partner; ages were dichotomized as younger than 20 and 20 or older. The distribution of respondents by both their own and their mothers' reproductive experience was analyzed in relation to various characteristics, and logistic regressions assessed possible associations between these variables and pregnancy experience.
Thirty percent of women reported getting pregnant before age 20, and 21% of men said they were younger than 20 when they first impregnated a partner. Of these groups, 34% of women and 31% of men reported that their mothers had first given birth at the same age. Both women and men were more likely to have had an early pregnancy experience if their mother had had a child before age 20 (odds ratios, 2.0 and 2.3, respectively). Among women, this positive association disappeared in the final model after adjusting for their education level, whereas among men the association remained after similar adjustment (1.8).
Daughters' and sons' level of education appears to be an important factor in the repetition of adolescent fertility across generations. Efforts are needed to increase access to education and to encourage young people to remain in school.
青少年怀孕与青少年母亲的早育经历有关,而年轻人的教育水平被认为是这一现象的重要因素。
2002 年,一项具有代表性的家庭调查从巴西三个城市的 3050 名 20-24 岁的年轻男性和女性中收集数据。主要措施是母亲的初育年龄、女儿的初次怀孕年龄和儿子首次使伴侣怀孕的年龄;年龄分为<20 岁和≥20 岁。根据受访者自身及其母亲的生育经历的分布情况,分析了与各种特征的关系,并采用逻辑回归评估了这些变量与怀孕经历之间的可能关联。
30%的女性报告在 20 岁之前怀孕,21%的男性报告在 20 岁之前首次使伴侣怀孕。在这些群体中,34%的女性和 31%的男性报告说他们的母亲在同样的年龄初育。如果母亲在 20 岁之前生育过孩子,女性和男性都更有可能有早期怀孕经历(比值比分别为 2.0 和 2.3)。在女性中,在调整了教育水平后,这种正相关关系在最终模型中消失了,而在男性中,在进行类似调整后,这种关联仍然存在(1.8)。
女儿和儿子的教育水平似乎是代际间青少年生育重复的一个重要因素。需要努力增加受教育机会,并鼓励年轻人继续上学。
