The aim of this study is to identify the prevalence of pregnancy and abortion experience, along with associated factors among street children, adolescents and youths in Porto Alegre and Rio Grande, RS, Brazil. The sampling method in this cross-sectional study was Respondent-Driven Sampling (RDS), innovative in research about hidden populations. Interviews were conducted with 307 subjects, aged 10 to 21 years. In multivariate analysis, Poisson regression with a robust error variance was used. Most of this sample were males, with no contact with school and family. Almost half of the participants had been on the street for five years or more, spending more than 15 hours per day on the streets. The prevalence of pregnancy experience was 29.3%, independently associated with being a girl, having 10 sexual partners or more in the last year, having a fixed sexual partner in the last year, and being older. The prevalence of abortion experience was 10.4%, independently associated with not living with the family, having more than two pregnancies, and being younger. The high prevalence of pregnancy and abortion experience highlights the need for the development of better sexual and reproductive health policies focused on this population.
本研究旨在确定巴西南里奥格兰德州阿雷格里港街头儿童、青少年和青年的怀孕和堕胎经历的患病率及其相关因素。本横断面研究的抽样方法是应答驱动抽样（RDS），这在针对隐藏人群的研究中具有创新性。对307名年龄在10至21岁的受试者进行了访谈。在多变量分析中，使用了具有稳健误差方差的泊松回归。该样本中的大多数为男性，与学校和家庭无联系。几乎一半的参与者在街上流浪了五年或更长时间，每天在街上花费超过15小时。怀孕经历的患病率为29.3%，独立相关因素包括为女性、去年有10个或更多性伴侣、去年有固定性伴侣以及年龄较大。堕胎经历的患病率为10.4%，独立相关因素包括不与家人同住、怀孕超过两次以及年龄较小。怀孕和堕胎经历的高患病率凸显了制定针对这一人群的更好的性与生殖健康政策的必要性。
