Abstract

Background: The objective of this study was to estimate the prevalence of adolescent pregnancy among sexually active adolescents, and identify the factors associated with this problem.

Methods: A population-based analytical cross-sectional study was conducted using pooled data from the Demographic and Family Health Surveys of Peru, 2015-2019. A total sample of 8850 adolescent girls aged 12 to 19 years who reported a history of sexual intercourse were included. To identify factors related to adolescent pregnancy, the study employed adjusted prevalence ratios (aPR) with 95% confidence intervals (95% CI). The aPR were obtained from a multivariable logistic regression model.

Results: The prevalence of adolescent pregnancy among sexually active adolescents in Peru was 30.9% (95%CI: 29.4-32.4%). In the multivariable analysis; being 17-19 years (aPR: 1.48; 95%CI:1.33-1.64), being married or cohabitant (aPR: 4.01; 95%CI: 3.48-4.61) and belonging to the Quechua ethnicity group (aPR: 1.16; 95%CI: 1.07-1.25), were associated with a higher prevalence. Conversely, the following factors were associated with a lower prevalence of pregnancy: being employed (aPR: 0.81; 95%CI: 0.76-0.86), being currently studying (aPR: 0.43; 95%CI: 0.38-0.49), belonging to the second (aPR: 0.91; 95%CI: 0.85-0.97), third (aPR: 0.81; 95%CI: 0.74-0.89), fourth (aPR: 0.79; 95%CI: 0.69-0.91) and fifth (aPR: 0.59; 95%CI: 0.47-0.75) wealth quintile, initiating sexual relations in middle adolescente (aPR: 0.76; 95%CI: 0.69-0.83) or late adolescence (aPR: 0.40; 95%CI: 0.35-0.46), perceiving a future pregnancy as a problem (aPR: 0.77; 95%CI: 0.72-0.83) and having knowledge of the moment in the cycle when pregnancy can occur (aPR: 0.84; 95%CI: 0.77-0.92).

Conclusions: Approximately three out of ten adolescents who initiated a sexual life had at least one pregnancy. Age, marital status, employment, education, wealth, ethnicity, age at first intercourse, knowledge of when in the cycle she may become pregnant, and perception of future pregnancy were associated with adolescent pregnancy. To decrease the prevalence of teenage pregnancy in Peru, it is imperative to enhance national policies concerning family planning and provide comprehensive sex education targeted at adolescents.
