RESUMEN

Study objectives: The aim of this article is to describe the problem of pregnancy in girls under 15 years of age in the Dominican Republic in the period 2000-2021, to develop a specific indicator for this age group and describing the related factors. Methods: This is an exploratory ecological study, based on secondary data sources, such as birth records from the National Statistics Office (NSO) and the Ministry of Public Health (MPH). We calculated the rates of fertility and pregnancy in early adolescence, as well as analyzed their main determining factors and consequences. Results: Fertility Rate in Early Adolescence (FREA) decreases from 6.27 to 1.04 per thousand in the period 2001-2021. The average FREA for 2015-2021 was 1.78. The average Estimated Rate of Pregnancy in Early Adolescence (ERPEA) for the same period was 3.39. Disability-Adjusted Life Years (DALYs) were 11,620 years. Years of Life Lost (YLL) were 9,665.9 years. The prevalence of Low Birth Weight (LBW) in the under 15-year-old age group was 14.2 %. Conclusions: Pregnancy in childhood implies risks for both the mother and the child, including low birth weight. The official fertility rate is substantially underreported (2.84 vs. 1.79).The fertility rate indicator traditionally used does not accurately measure the number of pregnancies in women, particularly in specific age groups or populations where pregnancies may be interrupted by various factors. Therefore, the use of ERPEA is recommended.We emphasize the need for implementing the proposed indicator for the target group, as well as monitoring Sustainable Development Goal indicator 3.7.2.
