The Use of Contraception and Adolescent Fertility in Indonesia

INTRODUCTION: Fertility in adolescents is closely related to the incidence of early marriage which will have an impact on increasing the incidence of pregnancy in adolescents so that it will directly affect the health of mothers and babies. The younger the age at marriage, the higher the fertility rate. AIM: This study aimed to determine the relationship between contraception and fertility among ado­lescents. METHODS: This quantitative study used a cross-sectional design. The population of this study was adolescents aged 15–19 years in Indonesia. The total sample of 7,547 adolescents was selected from the 2017 Indonesia Demographic and Health Survey (IDHS). Multivariate analysis using binary logistic regression was used to analyze the independent variable (contraception use) on the dependent variable (fertility) with education, work status, region, age at first sexual intercourse, economic status, and marital status as the controlled variables. RESULTS: Multiple logistic regression analysis was used to report the relationship between independent and dependent variables controlled by potential confounder variables. The results showed that the odds ratio of contraceptives users was 46 times compared to non-user after being controlled by confounding variables (AOR=4.8; 95%CI 33.857 – 441.046) after controlled by economic status, age at first exual intercourse, and marital status. CONCLUSION: The relationship between contraceptive use and fertility in adolescents is affected by confounding variables such as age at first sexual intercourse, economic status, and marital status. In addition, the odds ratio of contraceptives users was 46 times compared to non-users after being controlled by confounding variables.
