Tokyo Teen Cohort study (TTC)
The TTC study is a prospective population-based birth cohort study aimed at investigating physiological and psychological development during adolescence. This multidisciplinary study collects data from various sources (parent, child, and interviewer) through multiple methods (maternity record, self-report, interview, neurocognitive tests, biological measures, and neuroimaging). The cohort members for this study were drawn from children who completed the Tokyo Early Adolescence Survey (T-EAS). The participants are from three municipalities of Tokyo, Japan, and 47% of the sample were female.
