Aim: The aim of this study was to investigate whether parental somatic illnesses during childhood increase the risk for later psychosis in the offspring. In addition, we examined which parental illnesses in particular are associated with increased risk of psychosis in the offspring.

Method: The data of the Northern Finland Birth Cohort 1986 (NFBC 1986), included 9137 children born alive in northern Finland between the July 1, 1985, and the June 30, 1986. Information regarding the parents’ somatic morbidity was collected through various healthcare registers up to age 28 of the cohort members.

Results: Psychosis was diagnosed in 169 (1.8%) of the cohort members between the ages of 16 and 28. Accumulation of parental somatic diseases was related to later psychosis in the offspring. In addition, some specific somatic diagnostic groups of parents were emphasized in relation to psychosis in the offspring.

Conclusions: Our study findings indicated that parental somatic illness should be taken into account in the prevention of serious mental health problems in their offspring.
