School performance and later diagnoses of nonaffective psychoses, bipolar disorder, and depression.

ABSTRACT:

Objective

It is unclear whether there are differences between specific school subject performance and later psychiatric disorders. We examined whether mean grade point average (MGPA) and specific school subjects associated with diagnoses of nonaffective psychoses, bipolar disorder and depression.

Methods

In this register-based study, we studied the Finnish population born in 1987 who had available MGPA and six specific school grades (age = 15.4-16.4 years; n = 50,508). Grades were analyzed with smoothing splines. Covariates included sex, urbanicity, parental education level and parental diagnosed psychiatric disorders. Outcomes were incident nonaffective psychosis, bipolar disorder and depression diagnosed in specialized services until year 2015 (age = 28.0-28.9 years).
