Prevalence of rapid repeat pregnancy and associated factors in adolescents in Caruaru, Pernambuco

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Objectives:

to determine the prevalence and factors associated with the rapid repeat pregnancy (RRP) in pregnant adolescents.

Methods:

a cross-sectional study was carried out with pregnant adolescents assisted at the Family Health Strategies in Caruaru-PE from March to August 2013. A questionnaire with sociodemographic, economic, schooling, gynecological, obstetric and contraceptive characteristics was used. The data were analyzed in the Statistical Package for Social Sciences (SPSS), version 20. Binary logistic regression models were used.

Results:

among the 204 pregnant adolescents interviewed, the data of 26.5% (n = 54) multiparous were analyzed. The occurrence of RRP was 42.6% (n = 23) [95% CI 29.23-56.79]. The variables associated with RRP were non-use of contraceptive methods [OR 7.40 (CI95% 1.56-3.49)] and no previous pregnancy planning [OR 0.19 (95% CI 0.05-0.78)].

Conclusions:

the percentage of RRP in adolescents was high. The non-use of contracep-tive methods increased the chances of RRP, while the no previous pregnancy planning decreased the chances of adolescents getting pregnant again without previous program-ming.

Key words:
Pregnancy in adolescence; Sexual behavior; Reproductive health
