<jats:p>To assess the use of oral contraceptives (OC) in adolescents, using data from a longitudinal, population-based pediatric cohort study (LIFE Child). We also investigated associations between OC use and socioeconomic status (SES), and associations between OC use and potential adverse drug reactions such as effects on blood pressure. We included 609 female participants of the LIFE Child cohort, aged ≥13 to <21 years, who visited the study center between 2012 and 2019. Data collection compromised drug use in the past 14 days, SES, and anthropometric data such as blood pressure. An analysis of covariance was used to detect potential associations between participants’ blood pressure and OC. Multivariate binary logistic regression was used to obtain odds ratios (aOR) adjusted for age and 95% confidence intervals (95% CI). The prevalence of OC use was 25.8%. OC intake was less common in participants with a high SES (aOR 0.30, 95% CI 0.15, 0.62). The mean age at OC initiation did not change between 2012 and 2019. We observed an increased use of second-generation OC (2013: 17.9%, 2019: 48.5%; p = 0.013) and a decreased use of fourth-generation OC (2013: 71.8%, 2019: 45.5%; p = 0.027). We found a higher systolic (mean: 111.74 mmHg, p < 0.001) and diastolic (69.15 mmHg, p = 0.004) blood pressure in OC users compared to non-users (systolic: 108.60 mmHg; diastolic: 67.24 mmHg). Every fourth adolescent took an OC. The share of second-generation OC increased during the study period. OC intake was associated with low SES. OC users had a slightly higher blood pressure than non-users.</jats:p>
