Eligibility
Inclusion criteria
Inclusion criteria: Biomarker- outcome associations are tested in child (2-18 years) cohorts and for epigenetics also in adults. Inclusions into the original population-based cohort studies were voluntary.
Exclusion criteria
Exclusion criteria: For genetic studies, to avoid population stratification, ancestries that are different from EU are excluded

|---|---|
| Measures of association (from regression analyses) for biomarker-outcome analyses. For each set of biomarkers (metabolomics, SNP and epigenetic data) an appropriate level of statistical significance is specified. Outcome data on problem behaviors were collected by birth and child cohorts by standardized surveys. The most commonly employed instruments to assess childhood aggressive and attention problems came from the Achenbach System of Empirically based Assessment (ASEBA; Achenbach et al. 2017) and the Strengths and Difficulties Questionnaire (SDQ; Goodman 2001). These two instruments accounted for > 70% of the phenotype data. -Achenbach TM, Ivanova MY, Rescorla LA (2017) Empirically based assessment and taxonomy of psychopathology for ages 1½–90+ years: Developmental, multi-informant, and multicultural findings.
