From the third month of pregnancy to 1 year postpartum. Prevalence, incidence, recurrence, and new onset of depression. Results from the Perinatal Depression―Research & Screening Unit study

OBJECTIVE Perinatal depression is a particular challenge to clinicians, and its prevalence estimates are difficult to compare across studies. Furthermore, to our knowledge, there are no studies that systematically assessed the incidence of perinatal depression. The aim of this study is to estimate the prevalence, incidence, recurrence, and new onset of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, minor and major depression (mMD) in an unselected population of women recruited at the third month of pregnancy and followed up until the 12th month postpartum. METHOD One thousand sixty-six pregnant women were recruited. Minor and major depression was assessed in a naturalistic, longitudinal study. The Edinburgh Postnatal Depression Scale and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Disorders were administered at different time points during pregnancy and in the postpartum period. RESULTS The period prevalence of mMD was 12.4% in pregnancy and 9.6% in the postpartum period. The cumulative incidence of mMD in pregnancy and in the postpartum period was 2.2% and 6.8%, respectively. Thirty-two (7.3%) women had their first episode in the perinatal period: 1.6% had a new onset of depression during pregnancy, 5.7% in the postpartum period. CONCLUSIONS Our postpartum prevalence figures, which are lower than those reported in the literature, may reflect treatment during the study, suggesting that casting a multiprofessional network around women in need of support may be potentially useful for reducing the effects of this disorder on the mother and the newborn child. Furthermore, our results indicate that women with a history of depression have a 2-fold risk of developing mMD in the perinatal period.

Beyond “postpartum depressions”: Specific anxiety diagnoses during pregnancy predict different outcomes: Results from PND-ReScU

OBJECTIVE Literature underlines that the Edinburgh Postnatal Depression Scale (EPDS) is the most common measure to assess postpartum depression (PPD) worldwide and suggests that the rate of false positives is high. Furthermore, the EPDS does not distinguish between depression and anxiety. This study describes different definitions of PPD and whether pregnancy anxiety disorders are risk factors for different PPDs at both 1month and 1year postpartum. METHOD 1066 women were recruited during pregnancy and followed until the 12th month postpartum (N=500). Women were administered the SCID and completed the PDPI-R during pregnancy. During the postpartum women who had an EPDS score of 13 or more were administered the SCID to distinguish minor or major depressive episodes (mMD) from false positives. RESULTS 41.5% and 44.9% of the PPD assessed with the EPDS were false positives at the 1st month and during the 1st year postpartum respectively. The difference observed in prevalence rates estimated with EPDS and SCID was statistically significant both at the 1st month and during the 1st year postpartum. Overall the effect of anxiety diagnoses in predicting PPD was stronger at the 1st month than during the 1st year postpartum. The role of panic disorder is associated both with probable depression (ES=0.82) and with mMD (ES=0.87) at the 1st month postpartum, and predicted mMD during the 1st year postpartum (ES=0.71). OCD predicted false positives at the 1st month postpartum (ES=0.89). CONCLUSION An antenatal screening of specific anxiety diagnoses could be extremely useful for the prevention of possible postpartum distress outcomes.

P02-373 - Prevalence, incidence, recurrence and new onset of depression durin pregnancy. results from the perinatal depression-research & screening unit (PND-RESCU) study

Objectives Perinatal depression is a particolar challenge to clinicians, and its prevalence estimates are difficult to compare across studies. Furthermore,there are no studies that systematically assessed the incidence of perinatal depression. The aim of this study is to estimate prevalence, incidence, recurrence and new onset of DSM IV minor and major depression (mMD) in an unselected population of pregnant women. Method 1066 pregnant women were recruited at third month of pregnancy (T0), and minor/major depression (mMD) was assessed by the Structured Clinical Interview for DSM IV disorders (SCID I). The SCID I was administered at baseline evaluation (T0), the Edimburgh Postnatal Depression Scale (EPDS) was administered at third, 6th (T1), 8th (T2) month of pregnancy, and the SCID I Mood module was administered to confirme an eventual DSM-IV minor or major depression diagnosis when the EPDS score was≥13. Result The pregnancy period prevalence of mMD was 12,4%.The point prevalence of mMD decreased from 8,6% at the 3rd month of pregnancy to 1,7% at the 8th month of pregnancy.The cumulative incidence of mMD was 2,2%. The weighted incidence of new onsets during pregnancy was 1,6%. The weighted percentage of recurrences during pregnancy was 3,7%. Conclusion The decline in the point prevalence during the second and third trimester of pregnancy found in our study may be attributed to psychological counselling and/or pharmacological treatment.Further studies about new onsets of depression during pregnancy are highly important in order to improve clinical prediction of risk in any individual woman.

The complex interplay between gastrointestinal and psychiatric symptoms in irritable bowel syndrome: A longitudinal assessment: Irritable bowel syndrome and psychiatric symptoms

The aims of this study were to better define the relationship between irritable bowel syndrome (IBS) and psychiatric disorders and to examine the efficacy of paroxetine in the treatment of IBS patients.

PW01-260 - Depression during pregnancy: comparison between pregnant depressed women and non pregnant depressed women

Object Depression during pregnancy is associated to physical symptoms that can impair the functioning of women; furthermore some of the depression somatic symptoms (i.e., sleep disturbance, fatigue, weight change and appetite) are also features of pregnancy. The overlap of symptomatology can interfere with the identification and the diagnosis of the mood episode. Aim of this study is to compare the the depressive phenomenology and the presence of Axis I comorbidity between pregnant and non pregnant depressed women. Method We diagnosed Major Depression (MD) using the Structured Clinical Interview for Axis I Diagnosis DSM IV (SCID I) in 32 pregnant women at third month of pregnancy and 87 non pregnant women and we compared the depressive phenomenology in the two groups. Then we administered the Mood Spectrum Self Repost Last Month (MOOD SR-LM) in the two group in order to study the mood spectrum symptomatology. Result Pregnant depressed women have higher psychomotor retardation, higher levels of concentration and lower agitation than non pregnant depressed women. The severity of depression symptoms was similar in the two depressed groups. Conclusion Our results agree with current litterature about the presence of psychomotor retardation in depressed pregnant women. The higher level of concentration in pregnant women could be explained by the high comorbidity with Generalized Anxiety Disorder (GAD). In the pregnant depressed women the Obsessive-Compulsive Disorder (OCD) and Panic Disorder (PD) comorbidity are more rappresentated.
