Abstract:For the first time since the beginning of Brazil’s fertility decline, its schedule has stopped rejuvenating. A key factor for this phenomenon is the sharp decrease of fertility among teenagers in the first decade of the 21st century. This paper examines recent changes in two determinants of reproductive behavior of adolescents and young women in Brazil: the use of contraceptives and the ideal number of children. Using data from the 1996 Demographic and Health Survey (DHS) and the 2006 Pesquisa Nacional de Demografia e Saúde (PNDS), changes in the use of contraceptives and reproductive preferences according to age groups and cohorts are examined. The results show a great increase in the use of contraception among adolescents and young women and indicate an increase in preference for low parity and a decrease in the average ideal number of children across cohorts. The early fertility schedule in Brazil in addition with lower expectations regarding future fertility strongly suggest that there is a lot of room for further decline of fertility in the country. The study emphasizes recent and not yet investigated changes in adolescents and young women' reproductive behavior in Brazil and sheds light on the likely continuation of changes in the Brazilian fertility schedule and level.

巴西恢复生育计划的终结：来自青少年和年轻女性避孕使用和生殖偏好变化的证据

摘要：巴西生育率下降以来，首次停止了生机勃勃的日程。造成这种现象的一个关键因素是 21 世纪头十年青少年生育率的急剧下降。本文考察了巴西青少年和年轻女性生殖行为的两个决定因素的近期变化：避孕药具的使用和理想的儿童数量。使用来自 1996 年人口与健康调查 (DHS) 和 2006 年国家人口与健康调查 (PNDS) 的数据，根据年龄组和队列检查了避孕药具使用和生育偏好的变化。结果表明，青少年和年轻女性使用避孕方法的人数大幅增加，并表明对低胎次的偏好有所增加，而各队列的平均理想儿童人数有所减少。巴西的早期生育计划以及对未来生育率的较低预期强烈表明该国生育率进一步下降的空间很大。该研究强调了巴西近期和尚未调查的青少年和年轻女性生育行为的变化，并阐明了巴西生育计划和生育水平可能会继续发生变化。巴西的早期生育计划以及对未来生育率的较低预期强烈表明该国生育率进一步下降的空间很大。该研究强调了巴西近期和尚未调查的青少年和年轻女性生育行为的变化，并阐明了巴西生育计划和生育水平可能会继续发生变化。巴西的早期生育计划以及对未来生育率的较低预期强烈表明该国生育率进一步下降的空间很大。该研究强调了巴西近期和尚未调查的青少年和年轻女性生育行为的变化，并阐明了巴西生育计划和生育水平可能会继续发生变化。
