Abstract:

OBJECTIVE: In a previous study, the authors demonstrated an association between prenatal famine in middle to late gestation and major affective disorders requiring hospitalization. In this study, they sought to examine the association by using newly identified cases from the Dutch birth cohort used previously to examine the gender specificity of the association and to assess whether this relation is present for both unipolar and bipolar affective disorders.

METHOD: The authors compared the risk of major affective disorder requiring hospitalization in birth cohorts who were and were not exposed, in each trimester of gestation, to famine during the Dutch Hunger Winter of 1944-1945. These cases of major affective disorder requiring hospitalization were newly ascertained from a national psychiatric registry. A larger data set from this registry was used for analysis by gender and diagnostic subtype.

RESULTS: For the newly ascertained cases, the risk of developing major affective disorder requiring hospitalization was increased for subjects with exposure to famine in the second trimester and was increased significantly for subjects with exposure in the third trimester, relative to unexposed subjects. For the cases from the entire period of ascertainment, the risk of developing affective disorder was significantly increased for those exposed to famine during the second and the third trimesters of gestation. The effects were demonstrated for men and women and for unipolar and bipolar affective disorders.

CONCLUSIONS: These results provide support for the authors' previous findings on the association between middle to late gestational famine and affective disorder.

FAB RESEARCH COMMENT:

Findings from this study confirm and extend earlier findings of a link between prenatal famine and subsequent mood disorders in the adult offspring - in the form of depression and bipolar disorder serious enough to require hospitalisation.

The earlier findings (using a smaller dataset) showed an association in males only, and for maternal famine-induced malnutrition in the second trimester of pregnancy.  This study confirmed that link, but also found associations for both male and female offspring, and for prenatal famine in both the second and third trimester.  Furthermore, these associations were found for both unipolar and biploar depression.
