Finnish Health in Teens study (Fin-HIT)
The Fin-HIT Study is a prospective cohort study including over 11,000 Finnish adolescents (aged 9 - 12 years at enrolment), and nearly 10,000 parents; the vast majority of whom are mothers. The study was initiated in 2011 and the cohort is planned to be followed until 2035. Baseline data collection was between 2011-2014, first follow-up data collection was between 2015-2016, and national health register linkages were conducted in 2017-2018. Participants come from 44 municipalities, including Finland’s largest cities.
