Background: In South Asian region particularly in Bangladesh, adolescent pregnancy is still a major public concern. Therefore, identification of potential risk factors of adolescent pregnancy and childbearing may help to formulate policy to prevent premature delivery, death and disability.
Objectives: The main objective of this study was to identity the determinants factors of adolescent pregnancy in Bangladesh.
Study design: Retrospective two-stage stratified sample design.
Methods: Data were extracted from nationally representative Bangladesh Demographic and Health Survey conducted in 2011. In this study, age of childbearing was considered as dependent variable and classified as adolescent (≤19 years) and adult (>19 years). Several individual, household and community level factors were considered as the independent variables. Multilevel logistic regression model with household and community random intercept was used to identify the association between dependent and independent variable.
Results: The study found that about 28% adolescent had given birth in Bangladesh. Higher educated women (OR=0.65, 95% CI, 0.49-0.96), husband with higher education (OR=0.69, 95% CI, 0.56-0.84) and age at first marriage after age 15 years (OR=0.50, 95% CI, 0.45-0.55) were found to be protective for adolescent pregnancy. Secondary educated women (OR, 1.21; 95% CI, 1.03-1.39) showing the higher adolescent pregnancy than women with no education. The risk is high among women in Rangpur (OR=1.19; 95% CI, 1.12 1.25), followed by Khulna (OR=1.16; 95% CI, 1.09 1.23), Rajshahi (OR=1.16; 95% CI, 1.09 1.23) division showing among in Barisal division.
Conclusion: Around one fourth of the total pregnancy occurred adolescent age in Bangladesh which is caused by various individual, household and community-level factors. Proper education and increase awareness about the adverse effect of adolescent pregnancy are necessary to reduce occurrence of adolescent pregnancy in Bangladesh.
