Major and minor depression in pregnancy

Area of Science:

• Obstetrics and Gynecology
• Psychiatry
• Perinatal Mental Health

Background:

• Depression during pregnancy, encompassing major and minor forms, is a significant concern affecting maternal well-being.
• Understanding the temporal dynamics and etiological factors of prenatal depression is crucial for effective intervention.

Purpose of the Study:

• To investigate the onset, duration, and specific risk factors associated with major and minor depressive episodes in pregnant women.
• To differentiate the characteristics of major and minor depression within a prenatal care setting.

Main Methods:

• A cohort of 154 pregnant women attending prenatal care centers were assessed monthly for depressive symptoms using validated scales (Primary Care Evaluation of Mental Disorders, Hospital Anxiety and Depression Scale).
• Statistical analyses included one-way ANOVA with Bonferroni post-hoc tests for continuous variables and Fisher exact test for categorical variables to compare groups.

Main Results:

• Major depression (12.3%) and minor depression (18.1%) were diagnosed. Major depression showed later onset (5.6 months) and longer duration (2.3 months) compared to minor depression (3.5 months onset, 1.6 months duration).
• Risk factors for major depression included prior depressive episodes (OR 9.5) and partner conflict (OR 7.8). Minor depression risk was associated with being a housewife (OR 7.2), prior episodes (OR 4.7), and unwanted pregnancy (OR 2.4).

Conclusions:

• Major and minor depression frequently impact pregnant women, especially those with a history of depression.
• These conditions exhibit different risk profiles, onset times, and durations, with most cases presenting as mild and short-lived.
