The Northern Finland Birth Cohort 1986 is a large population-based birth cohort, which aims to promote health and wellbeing of the population. In this paper, we systematically review the psychiatric research performed in the cohort until today, i.e. at the age of 32 years of the cohort (2018). We conducted a systematic literature search using the databases of PubMed and Scopus and complemented it with a manual search. We found a total of 94 articles, which were classified as examining ADHD, emotional and behavioural problems, psychosis risk or other studies relating to psychiatric subjects. The articles are mainly based on two large comprehensive follow-up studies of the cohort and several substudies. The studies have often used also nationwide register data. The studies have found several early predictors for the aforementioned psychiatric outcomes, such as problems at pregnancy and birth, family factors in childhood, physical inactivity and substance use in adolescence. There are also novel findings relating to brain imaging and cognition, for instance regarding familial risk of psychosis in relation to resting state functional MRI. The Northern Finland Birth Cohort 1986 has been utilised frequently in psychiatric research and future data collections are likely to lead to new scientifically important findings.Abbreviations: attention deficit hyperactivity disorder (ADHD); magnetic resonance imaging (MRI)

Background: Children affected by parental traumatic brain injury (TBI) are documented to access more specialised psychiatric services compared to their peers. It remains unknown if the service use indicates psychiatric disorders. Objective: To investigate whether parental TBI increases the overall risk for psychiatric disorders and the risk for specific psychiatric diagnoses in the children affected by parental TBI. Methods: The 1987 Finnish Birth Cohort (n = 59 476) were followed up through national registers from birth to the end of 2008. The diagnoses of cohort members and their parents were obtained from the Care Register of Health Care, provided by the National Institute of Health and Welfare. Results: During the 21-year follow-up, the likelihood for psychiatric diagnoses being assessed in psychiatric care was significantly increased in males with any mental disorder (odds ratio (OR) = 1.43), substance-use-related disorders (OR = 1.71) and behavioural and emotional disorders (OR = 1.75), and in females with disorders of psychological development (OR = 1.85). Conclusions: Children affected by parental TBI are at increased risk for psychiatric disorders: males for externalising disorders and females for developmental disorders. Observed gender interactions in the association between parental TBI and the psychiatric disorders of children warrants further study.
