Adolescent abortion in 11 high-income countries including Australia: towards the establishment of a minimum data set

A major public health challenge in Australia is the lack of national adolescent abortion data. This descriptive study identifies, collates and describes publicly available adolescent abortion data in high-income countries including Australia, to describe trends over 10 years and provide recommendations for strengthening data collection.

Data were extracted from publicly available government sources that met inclusion criteria. All relevant adolescent abortion data from 2007 to 2017 were extracted from datasets and analysed.

Eleven high-income countries were included. Incidence data for the adolescent population were available for all countries and states. Incidence of adolescent abortion over 10 years shows a downward trend in all countries. Gestational age at time of abortion was the second-most available variable. The level and type of data across all countries varied; there was a lack of age range standardisation and aggregation of gestational weeks differed, making comparisons difficult.

A minimum data set of standardised abortion information will enable appropriate adolescent abortion policies and services to be developed that are informed by high quality, up-to-date intelligence. Implications for public health: Availability of data affects government's ability to adequately monitor national adolescent health outcomes and plan and evaluate appropriate reproductive health policy and services.
