Prevalence and related factors of common mental disorders during pregnancy in Japan: a cross-sectional study

Abstract

BackgroundCommon mental disorders (CMD) during pregnancy can have a clearly harmful influence on both mothers and children. Some studies have reported related factors for mental disorders, such as region-specific background. This study examined the prevalence of CMD and its related factors in mid-pregnancy in Japan.MethodsPregnant women between 12 and 24 weeks gestation and aged ≥20 years were consecutively recruited at a maternity hospital in Japan between May 2014 and September 2014. CMD were diagnosed using the Mini-International Neuropsychiatric Interview (MINI), self-rated depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale, and interpersonal traumatic experience was measured using the Life Events Checklist.ResultsAmong 297 eligible pregnant women, 177 participated in the study. Two participants (1.1 %) met the criteria for major depressive disorder. The most frequent diagnosis was agoraphobia (n = 7; 3.9 %). Eleven participants (6.2 %) met the criteria for one or more diagnoses, with 2 participants having two mental disorders and 3 having three mental disorders. Six participants developed CMD after gestation. Logistic regression analysis revealed history of psychiatric disorder, past interpersonal traumatic experience, and feeling pressure to have a child were associated with CMD.ConclusionThese findings indicate a lower prevalence of CMD in mid-pregnancy in Japan than reported in most other countries. Besides the related factors reported previously, feeling pressure to have a child might increase risk for CMD among pregnant women in Japan. Asian cultural background might be related to the lower CMD prevalence and risk factors identified in this study.

A Bayesian multivariate approach to estimating the prevalence of a superordinate category of disorders

“…These data are summarized in Table . Of these data, we retrieved IPD for 1,506 participants (Chaudron & Nirodi, ; Fadzil et al, ; Fairbrother, Janssen, Antony, Tucker, & Young, ; Fisher, Wynter, & Rowe, ; Matthey & Ross‐Hamid, ; Usuda et al, ; Zar, Wijma, & Wijma, ). The average number of disorders measured by a given study was 3.4; Figure depicts the percentage of participants diagnosed with at least one disorder as a function of the number of disorders measured.…”

The Prevalence of Anxiety Disorders During Pregnancy and the Postpartum Period

“…To accomplish this, the correlations between the individual anxiety disorders (representing comorbidity) were estimated using all available individual patient data. 45,46,55,[62][63][64][65] By estimating the correlations amongst disorders, we were also able to provide a meta-analytic summary of the comorbidities between disorders. Finally, study-level prognostic factors were explored by allowing the prevalence of each disorder to depend on one predictor variable at a time.…”

Erratum to: Prevalence and related factors of common mental disorders during pregnancy in Japan: a cross-sectional study

“…After publication of the original article [ 1 ], the authors noticed there was an error to the values for “Generalized anxiety disorder”, “Obsessive-compulsive disorder” and “PTSD (Post traumatic stress disorder)” listed underneath the “% (95% CI)” column. The correct version of Table 2 , is included in this erratum.…”
