In the group of young women of school age (<19 years), only one participant (aged 16.1 years) had not completed a qualification of GCSE level/NVQ or higher; this participant also did not describe themselves as being a student/in education. We were therefore confident to define this participant as having ‘no formal qualifications’.
For the adjusted models, this category was combined with ‘friends/acquaintances’ because of the small numbers.
