Pregnant again? Psychosocial predictors of short-interval repeat pregnancy among adolescent mothers in Mexico City.

Which adolescent mothers are most likely to become pregnant soon after their first delivery? This study identifies and explores selected background, pregnancy, and postpartum predictors of short-interval repeat pregnancy among urban Mexican adolescents who were single when they conceived their first pregnancy. Of 137 adolescents followed until their second postpartum year, 26 had short-interval repeat pregnancies. These pregnancies were most likely to occur if the teenager was married or in consensual union by 5 months postpartum, was not using an IUD, and had a mother who had been an adolescent mother. Being married or in consensual union postpartum was, in turn, predicted by positive reactions of the adolescent and her partner during the first pregnancy. Nonuse of IUD was more likely if the adolescent had left school prior to pregnancy, did not receive support from her partner during the first pregnancy, and had not obtained an IUD before hospital discharge after first delivery. Adolescents whose mothers had been teen mothers came from more disadvantaged families.
