Chedraui, L.A. Hidalgo, M.J. Chávez, G. San Miguel] Objective: Determine social factors related to pregnancy among young adolescents. Methods: We obtained socio-demographic data from early adolescent nulliparas aged ≤15 years. Results: During the study period at the Enrique C. Sotomayor Obstetrics and Gynecology Hospital, Guayaquil-Ecuador 201 early adolescent nulliparous patients of low socio-economic status were surveyed and compared with 201 low socio-economic nulliparous controls aged 20 to 30. Mean age of adolescents was 14±0.6 years, 58.7% of them were aged 14. Age of menarche and sexual initiation was lower among adolescents (11.8±0.9 vs 12.8±2 years and 12.6±1.1 vs 16.2±5 years, respectively, p<0.05). A higher rate of adolescents initiated sexually before menarche onset (18.4% vs 5%, p<0.05). The rate of those who wanted to become pregnant, had adequate prenatal care and had knowledge of conception, used contraception or had knowledge of any contraceptive method prior to pregnancy was significantly lower in adolescents (16.9% vs 86.5%; 37.3% vs 94.5%; 18% vs 70.1%; 6.5% vs 89.5%; 42.8% vs 84.5%, respectively, p<0.05). Age of sexual partner was lower in the adolescent group (20.4±3.4 vs 30±8 years, p<0.05). Compared to controls, higher rates of adolescents were school dropouts, had problems with the law and were involved in domestic violence (87% vs 9.9%, 7.5% vs 0.5%, 44.7% vs 2.5%, respectively, p<0.05). None of the adolescents were living with mother and father in a complete family structure. Parental illiteracy was higher among adolescents (9% vs 3.5%, p<0.05). Conclusion: In this low socio-economic population, early sexual initiation, poor reproductive health knowledge and the disruption of family structure Copyright © 2004 by Walter de Gruyter GmbH & Co.
