To identify sociodemographic characteristics associated with induced abortion of the first pregnancy and quantify the strength of association between them.
Data were gathered from a survey conducted in the district of Diez de Octubre, Havana, Cuba throughout 1991 and the beginning of 1992. The study population was divided into two comparable groups: one group of women whose first pregnancy terminated in induced abortion and a second group of women whose pregnancy terminated in childbirth. For the variables with statistically significant differences, both the crude and adjusted odds ratio were obtained for the one potentially confounding factor:age. Multivariate logistic regression analysis was employed in the final stage.
The sociodemographic characteristic identified as risk factor for induced abortion during the first pregnancy is being younger than 24 years of age, a risk which increased with women who were less than 20 years old, whether single or in union.
Recurrence risk of induced abortion during the first pregnancy is higher in younger women who have not achieved their professional, working or marrying expectations. This situation seem to be incompatible with maternity in the studied group.
确定与首次妊娠人工流产相关的社会人口学特征，并量化它们之间关联的强度。
数据收集自1991年全年及1992年初在古巴哈瓦那十月十日区进行的一项调查。研究人群分为两个可比组：一组是首次妊娠以人工流产告终的女性，另一组是妊娠以分娩告终的女性。对于具有统计学显著差异的变量，针对一个潜在混杂因素：年龄，得出了粗比值比和调整后的比值比。最后阶段采用多因素逻辑回归分析。
被确定为首次妊娠人工流产危险因素的社会人口学特征是年龄小于24岁，对于年龄小于20岁的女性，无论其单身还是已婚，这种风险都会增加。
首次妊娠人工流产的复发风险在未实现职业、工作或结婚期望的年轻女性中更高。在所研究的群体中，这种情况似乎与生育不相容。
