Objective: Previous studies have reported that adolescent pregnancy is associated with higher risks of adverse pregnancy outcomes (APO) compared to pregnancies after the age of 20. Although there have been accumulating evidence regarding age at reproductive event, such as menarche or menopause, and long-term cardiovascular (CVD) risk, there aren’t enough research on the effect of adolescent pregnancy on long-term outcome. This study aimed to evaluate the risk of long-term CVD after adolescent pregnancy using large cohort data.

Study Design: This study was based on the UK biobank database. Participants aged 40 to 69 years, who were recruited between 2006 and 2010, were analyzed. Clinical events were collected from the time of enrollment. The study population was divided into groups of first delivery before and after the age of 20. The risk of atherosclerotic cardiovascular disease (ASCVD) was evaluated according to adolescent pregnancy ( < 20 years) and adult pregnancy ( ≥ 20 years).

Results: Among 182,843 women in the UK biobank, 28,090 women had their first delivery at adolescence with an average age at childbirth of 18.69 years. The adolescent pregnancy group had lower rates of hypertensive disease during pregnancy (HDP) compared to the adult pregnancy group. However, the incidence of ASCVD was 8.4 % (2269/28,090) in the adolescent pregnancy group, compared to the adult pregnancy group. Even after adjusting for confounding variables, the risk of ASCVD remained higher in adolescent pregnancy group (HR 1.320; 95 % CI 1.245 to 1.398, p < 0.001).

Conclusion:

Adolescent pregnancy increases the risk of long-term ASCVD. Healthcare providers should focus on both prenatal care and long-term postpartum management for adolescent pregnancies. To improve potential risks and outcomes, appropriate care and comprehensive support are necessary throughout pregnancy and the postpartum period.
