REACH is an accelerated cohort study that comprises 4,353 adolescents in years 7 to 9 of school who were recruited from 12 mainstream secondary schools in London boroughs of Lambeth and Southwark, United Kingdom. The cohorts were recruited and first assessed at age 11 to 12 years (cohort 1, school year 7), 12 to 13 years (cohort 2, school year 8) and 13 to 14 years (cohort 3, school year 9). A sub-sample of around 180 from each cohort (total, around 540) were also recruited to complete more detailed interviews and assessments and provide biological samples at sweeps one and two.
