Pregnancy trends and associated factors among Kenyan adolescent girls and young women pre- and post-COVID-19 lockdown

ABSTRACT

Globally, COVID-19 has had a negative impact on health systems and health outcomes, with evidence of differential gender impacts emerging. The COVID-19 timeline of events spanning from closures and restrictions to phased reopenings is well-documented in Kenya. This unique COVID-19 situation offered us the opportunity to study a natural experiment on pregnancy trends and outcomes in a cohort of Kenyan adolescent girls and young women (AGYW), enrolled in the KENya Single-dose HPV-vaccine Efficacy (KEN SHE) Study. The KEN SHE Study enrolled sexually active AGYW aged 15–20 years from central and western Kenya. Pregnancy testing was performed at enrollment and every 3 months. We determined pregnancy incidence trends pre- and post-COVID-19 lockdown, pregnancy outcomes (delivery, spontaneous, or induced abortion), and postabortion and postpartum contraceptive uptake. Kaplan–Meier survival estimates of incidence rates were used to estimate the cumulative probability of pregnancy during the study period. Cox regression was used to investigate factors associated with pregnancy incidence. Of the 2,223 AGYW included in the analysis, median age was 18.6 IQR (17.6–20.3), >90% had at least secondary school education, 95% were single at the time of enrollment, and 82% had a steady/primary sexual partner. Pregnancy incidence peaked at 2.27 (95% CI [1.84, 2.81])/100 women-years of observation at the end of the first quarter of 2020, a period coinciding with the government-imposed lockdown. AGYW had 60% increased risk of being pregnant during the lockdown when compared to prelockdown period (HR = 1.60, 95% CI [1.25, 2.05]). Among the 514 pregnancies reported, 127 (25%) ended in abortion, of which 66 (52%) were induced abortions. Our findings demonstrate the adverse sexual and reproductive health (SRH) consequences of the COVID-19 pandemic and the lockdown measures among AGYW. As services continue to be disrupted by the pandemic, there is an urgent need to strengthen and prioritize AGYW-centered SRH services, including contraception and safe abortion.
