Abstract

Childhood experiences, personality, and polyunsaturated essential fatty acid (PUFA) composition have all been shown to affect the likelihood of depressive symptoms. Few studies have addressed relationships between these factors in their influence on the occurrence or course of depressive symptoms. The following analysis was designed to do so. Subjects, 15–20 years old, had either begun antidepressant treatment within the preceding month (n = 88), or had never taken psychiatric medications (n = 92). Baseline assessments included a structured diagnostic interview, the self-completed Multiphasic Personality Questionnaire, and a determination of plasma PUFA phospholipid composition. Depressive symptom levels were assessed at baseline and again at 4, 8 and 12 months. Omega-3 composition and general childhood trauma scores were unrelated to each other but both correlated, in predicted directions, with negative emotionality. Low omega-3 composition and history of childhood trauma were associated with persistence of depressive symptoms during follow-up, largely through their effects on negative emotionality. Negative emotionality appears to comprise a final common pathway to depressive disorder through which the diverse risk factors of childhood adversity and low omega-3 composition are expressed.
