Are pregnant women at higher risk of depression underdiagnosis?

Prevalence and associated factors of undiagnosed depression and generalized anxiety disorder among a national sample of women and men in Mozambique in 2022-23

BACKGROUND

The study's objective was to assess adult Mozambicans' prevalence and associated factors of undiagnosed depressive and anxiety disorders.

METHOD

This cross-sectional study analyzed data from the 2022-23 Mozambique Demographic and Health Survey (MDHS), including 13,183 women (aged 15-49 years) and 5380 men (aged 15-54 years) that completed the mental health module.

RESULTS

The analytic women sample (15-49 years) included 1619 females with depressive and/or anxiety disorders. The proportion of undiagnosed depressive and/or anxiety disorders were 81.0 % and 19.0 % had diagnosed depressive and/or anxiety disorders. The analytic men sample (15-54 years) included 288 males with depressive and/or anxiety disorders. The proportion of undiagnosed depressive and/or anxiety disorders was 67.4 % and 32.6 % had diagnosed depressive and/or anxiety disorders. In adjusted logistic regression analysis, Islamic, no, or other religion (Adjusted Odds Ratio-AOR: 1.16, 95 % Confidence Interval (CI): 1.04-1.29), currently pregnant (AOR: 1.13, 95 % CI: 1.05-1.21) were positively associated with undiagnosed depressive and/or anxiety disorders, and almost daily internet use (AOR: 0.75, 95 % CI: 0.64-0.87) was negatively associated with undiagnosed depressive and/or anxiety disorders. In addition, in univariable analysis, poorer wealth status, barriers to health care access (distance and financial) were positively associated with undiagnosed depressive and/or anxiety disorders, and currently working, urban residence, having health insurance coverage and cancer screening were negatively associated with undiagnosed depressive and/or anxiety disorders.

LIMITATIONS

Our findings only referred to participants having positive screening results of depressive and anxiety disorders, and no clinical diagnoses by medical providers were made.

CONCLUSIONS

The study makes a significant contribution to understanding mental health in Mozambique and highlights the critical need for improving mental health services, particularly for undiagnosed cases. These findings can inform policies and programmes aimed at better mental health outcomes across different population groups in Mozambique.

Prevalence of psychiatric disorders during pregnancy-a feasibility study at second trimester ultrasound in the general population (GROUP study): study protocol

INTRODUCTION

During the perinatal period, women have an increased risk for psychiatric disorders, which are highly prevalent in this context. In addition, there are significant delays in diagnosing these conditions, worsening their prognosis and increasing their societal burden. Studies describing psychiatric disorders in the perinatal period often focus on specific disorders; only postpartum depression and, to a lesser extent, anxiety disorders are studied. There are also very few evaluations conducted by clinicians based on a semistructured interview, relying on the diagnostic criteria of international nosography.

METHODS AND ANALYSIS

This multicentric prospective study will recruit 140 adult pregnant women based on randomly selected second trimester (T2) ultrasound consultations. The primary outcome is the prevalence of any psychiatric disorder assessed with a standardised psychiatric assessment, the Mini-International Neuropsychiatric Interview (M.I.N.I.). Within 10 days after the T2 ultrasound appointment, we will conduct the M.I.N.I., collect demographic data, evaluate suicidal behaviour with the Columbia-Suicide Severity Rating Scale, describe negative life events from the past year using the Paykel questionnaire and evaluation of social deprivation (Evaluation of the Deprivation and Inequalities of Health in Healthcare Centres score). Participants will also complete self-administered psychiatric questionnaires that screen for specific pathologies. We will build a biological sample collection. At two months post partum, we will repeat the questionnaires, adding an assessment of mother-child bonding. Patients can choose between in-person or telemedicine visits on both occasions.

ETHICS AND DISSEMINATION

All participants will be required to provide written informed consent. The study has received ethical approval from the French National Committee ('Comité de Protection des Personnes Ouest VI') (approval number: 23.03919.000236). Results will be disseminated through peer-reviewed journal publications and at scientific conferences and meetings.

Prevalence of depressive disorders among pregnant women in Brazil in 2019: A descriptive cross-sectional study

BACKGROUND

Prenatal depression threatens maternal and child well-being and interferes with issues prioritized by the 2030 agenda for the Sustainable Development Goals.

OBJECTIVES

This study aimed to estimate the prevalence of depressive disorders during pregnancy using the Patient Health Questionnaire-9 (PHQ-9).

DESIGN AND SETTING

A cross-sectional study using a sample of pregnant Brazilian women, representative of Brazil as a whole.

METHODS

Data were obtained from the National Health Survey 2019 (PNS-2019), as coordinated by the Instituto Brasileiro de Geografia e Estatística (IBGE). Women aged 18-49 years who were pregnant during PNS-2019 data collection were included. The prevalence of depressive disorders and 95% confidence intervals (95%CI) were calculated.

RESULTS

The prevalence of depression before the current pregnancy was 6.03% (95%CI: 3.80%; 8.25%). Using the PHQ-9, the prevalence of Major Depressive Disorder (MDD) in the current pregnancy was estimated to be 17.39% (95%CI: 12.70%-22.06%) among pregnant women who were targeted by the PNS-2019. Moreover, MDD was 15.26% (95%CI: 10.54%; 19.97%) among those who were free from depression history and in half of the pregnant woman population with depression history. Suicidal ideation has been reported in almost 23% of pregnant women with a history of depression. The two items from Patient Health Questionnaire-2 (PHQ-2) (anhedonia and depressed mood) with a cutoff of ≥ 3 presented similar results.

CONCLUSIONS

Depression during pregnancy affects a non-negligible proportion of pregnant women, thus constituting an important public health problem. Therefore, it is crucial to discuss the implementation of regular screening for depression during prenatal care programs in Brazil.

Joint effects of depression and social determinants of health on mortality risk among U.S. adults: a cohort study

BACKGROUND

Unfavorable social determinants of health (SDoH) are associated with depression. Both depression and SDoH are associated with increased risks of mortality, but their joint impacts on mortality risks remain unclear. This study aims to investigate the joint effects of depression and SDoH on mortality risk.

METHODS

Utilizing data from the National Health and Nutrition Examination Survey (NHANES) 2007-2018, 24,727 adults aged ≥ 20 were included. SDoH was assessed based on the 5 domains outlined in the U.S. Healthy People 2030 initiative. The cumulative number of unfavorable SDoH was calculated and categorized into low and high burden levels. The definition of depression was based on the Patient Health Questionnaire-9 (PHQ-9) scores ≥ 10. The joint associations of depression and SDoH with all-cause, cardiovascular disease (CVD), and cancer mortality were examined using Cox proportional hazard models.

RESULTS

We identified 2,377 (6.84%) all-cause deaths (CVD, 717; cancer, 606) during a median follow-up of 7.0 years. Depression was associated with increased mortality risks, and SDoH could explain 32.4% and 28.3% of the associations between depression and all-cause and CVD mortality, respectively. No significant interactions were observed between depression and SDoH on mortality. However, a low burden of unfavorable SDoH reduced the risk of all-cause mortality in depressed patients (hazard ratio [HR], 0.58; 95% confidence interval [CI]: 0.36-0.92). In the joint analysis, individuals with both depression and a high burden of unfavorable SDoH had the highest risks of all-cause and CVD mortality. Specifically, compared with individuals with no depression and a low burden of unfavorable SDoH, those with depression and a high burden of unfavorable SDoH had higher risks of all-cause (HR, 2.52; 95% CI: 2.01-3.18) and CVD mortality (HR, 2.79; 95% CI: 1.95-3.99).

CONCLUSION

Adults with both depression and a high burden of unfavorable SDoH had the highest risks of all-cause mortality and CVD mortality. The result suggests considering depression and SDoH jointly in developing targeted intervention strategies to improve survival outcomes and calls for larger cohort studies and clinical trials to validate our findings.

Diagnostic error in mental health: a review

Diagnostic errors are associated with patient harm and suboptimal outcomes. Despite national scientific efforts to advance definition, measurement and interventions for diagnostic error, diagnosis in mental health is not well represented in this ongoing work. We aimed to summarise the current state of research on diagnostic errors in mental health and identify opportunities to align future research with the emerging science of diagnostic safety. We review conceptual considerations for defining and measuring diagnostic error, the application of these concepts to mental health settings, and the methods and subject matter focus of recent studies of diagnostic error in mental health. We found that diagnostic error is well understood to be a problem in mental healthcare. Although few studies used clear definitions or frameworks for understanding diagnostic error in mental health, several studies of missed, wrong, delayed and disparate diagnosis of common mental disorders have identified various avenues for future research and development. Nevertheless, a lack of clear consensus on how to conceptualise, define and measure errors in diagnosis will pose a barrier to advancement. Further research should focus on identifying preventable missed opportunities in the diagnosis of mental disorders, which may uncover generalisable opportunities for improvement.

Effects of Two Group Prenatal Care Interventions on Mental Health: An RCT

INTRODUCTION

Perinatal depression and anxiety cost the U.S. health system $102 million annually and result in adverse health outcomes. Research supports that cognitive behavioral therapy improves these conditions, but barriers to obtaining cognitive behavioral therapy have prevented its success in pregnant individuals. In this study, the impact of a cognitive behavioral therapy-based intervention on anxiety, depression, stress, healthy lifestyle beliefs, and behaviors in pregnant people was examined.

STUDY DESIGN

This study used a 2-arm RCT design, embedded in group prenatal care, with one arm receiving a cognitive behavioral therapy-based Creating Opportunities for Personal Empowerment program and the other receiving health promotion content.

SETTING/PARTICIPANTS

Black and Hispanic participants (n=299) receiving prenatal care from 2018 to 2022 in New York and Ohio who screened high on 1 of 3 mental health measures were eligible to participate.

INTERVENTION

Participants were randomized into the manualized Creating Opportunities for Personal Empowerment cognitive behavioral therapy-based program, with cognitive behavioral skill-building activities delivered by advanced practice nurses in the obstetrical setting.

MAIN OUTCOME MEASURES

Outcomes included anxiety, depression, and stress symptoms using valid and reliable tools (Generalized Anxiety Disorder scale, Edinburgh Postnatal Depression Scale, and Perceived Stress Scale). The Healthy Lifestyle Beliefs and Behaviors Scales examined beliefs about maintaining a healthy lifestyle and reported healthy behaviors.

RESULTS

There were no statistically significant differences between groups in anxiety, depression, stress, healthy beliefs, and behaviors. There were significant improvements in all measures over time. There were statistically significant decreases in anxiety, depression, and stress from baseline to intervention end, whereas healthy beliefs and behaviors significantly increased.

CONCLUSIONS

Both cognitive behavioral therapy and health promotion content embedded in group prenatal care with advanced practice nurse delivery improved mental health and healthy lifestyle beliefs and behaviors at a time when perinatal mood generally worsens.

Risk of postpartum readmission for depression in relation to ischaemic placental disease: a population-based study

Background

There are limited data on postpartum readmissions for depression in the United States (US). Specifically, the extent to which ischaemic placental disease (IPD) during pregnancy predisposes patients to develop postpartum depression remains poorly understood. We investigated whether IPD is associated with postpartum readmission for new-onset depression in the first year after delivery.

Methods

In this population-based study, the 2010-2018 Nationwide Readmissions Database was utilised to evaluate rates of postpartum readmission for depression within the calendar year of delivery hospitalisation among patients with and without IPD. IPD was defined as preeclampsia, placental abruption, or small for gestational age (SGA) birth. We expressed associations between IPD and depression readmission based on a confounder-adjusted hazards ratio (HR) with a 95% confidence interval (CI).

Findings

Of 33.3 million delivery hospitalisations, 3,027,084 (9.1%) had IPD. The total follow-up among those with and without IPD were 17,855,830 and 180,100,532 person-months, respectively, with a median follow-up of 5.8 months for both groups. Rates of depression readmission were 95.7 (n = 17,095) and 37.5 (n = 67,536) per 100,000 readmissions among patients with and without an IPD, respectively (HR, 2.39; 95% CI, 2.32-2.47); this risk was the highest for preeclampsia with severe features (HR, 3.14; 95% CI, 3.00-3.29). Patients had a greater risk of readmission if they had any two forms of IPD (HR, 3.02; 95% CI, 2.75-3.33), and those with a concurrent diagnosis of preeclampsia and abruption posed the highest risk (HR, 3.23; 95% CI, 2.71-3.86).

Interpretation

These findings suggested that patients with IPD are at a substantially increased risk of readmission for depression within a year following delivery. This study underscores the need for increased surveillance, improved detection, and faster treatment of depression in this vulnerable population.

Point prevalence and sex-specific associated factors of depression in Latvian general population

Background

This cross-sectional study aimed to determine the current prevalence of depression, and analyze sex-specific associated socio-demographic and health-related factors for depression in a representative sample of the general adult population of Latvia.

Methods

Specially trained professional interviewers conducted computer-assisted face-to-face interviews with a multistage stratified probability sample from the general Latvian adult population (n = 2,687). A 9-item Patient Health Questionnaire (PHQ) was used for assessment of depression. Respondents were interviewed using the specially developed questionnaire about sociodemographic factors as well as the alcohol use disorder module of the Mini International Neuropsychiatric Interview. Binary logistic regression was used to calculate the odds ratios (OR) for the univariate and multivariate logistic analyses.

Results

The point prevalence of depression according to the PHQ-9 was 6.4% (95% CI 5.8-7.6). After adjustment for all independent variables analyzed, being divorced, widowed, or living separately increased the odds of depression [aOR 2.6 (95% CI, 1.2-5.8), p = 0.02] in males. For females, unfinished primary education [aOR 5.2 (95% CI 2.0-13.6), p = 0.001] and economically inactive status [aOR 2.0 (95% CI, 1.1-3.6), p = 0.03] were strongly associated with depression.

Limitations

The cross-sectional design of the study did not allow us to draw conclusions about causality. Patients with bipolar, organic, and symptomatic depression states were not excluded.

Conclusion

The prevalence of depression in the general adult population is 6.4%, with the most significant sex-specific factors associated with depression for males - being divorced, widowed, or living separately, and for females it was poor education and economic inactivity.

Socioeconomic and racial/ethnic inequalities in depression prevalence and the treatment gap in Brazil: A decomposition analysis

Depression is a major global health burden and there are stark socioeconomic inequalities in both the prevalence of depression and access to treatment for depression. In Brazil, racial/ethnic inequalities are of particular concern, but the factors contributing to these inequalities remain mostly unknown. This paper firstly explores determinants of depression and the treatment gap (i.e., untreated afflicted individuals) in Brazil and identifies if socio-economic and health system factors explain changes over time. Secondly, it analyses income and racial/ethnic inequalities in depression and the treatment gap and identifies factors explaining inequalities through decomposition methods. Data from two waves (2013 and 2019) of a representative household-based survey are used. In 2019, 10.8% of adults were depressed, but over 70% of depressed adults did not receive care. Black or brown/mixed Brazilians were more likely to have untreated depression, and region of residence was the most important determinant of these racial/ethnic inequalities. Notably, 44.6% of the difference in the treatment gap between white individuals and black and brown/mixed individuals was not explained by differences in observables, which could potentially be due to discrimination or difficulties in accessing treatment due to other non-observable characteristics. Employment, age, exposure to violence and physical activity are the main contributing factors to income inequalities in depression. These results suggest that policies aimed at improving the levels of exposure of lower-income individuals to risk factors may positively impact mental health and mental health inequalities, while addressing inequalities in service provision and resourcing for mental health and tackling barriers to access stemming from discrimination are essential to bridge the treatment gap equitably.

Mental health in pregnant individuals during the COVID-19 pandemic based on a Swiss online survey

The aim of our study was to evaluate the mental health of pregnant individuals during the early COVID-19 pandemic and the potential factors associated. A Swiss online survey was proposed to individuals who gave birth during the pandemic period from March 2020. The Edinburgh Postnatal Depression Scale (EPDS), Generalized Anxiety Disorder 7 questions (GAD-7), and Impact Event Scale-Revised (IES-R) were evaluated and used to defined mental health impairment as a composite outcome. From October, 2020 to February, 2021, 736 participants responded. The anxiety GAD-7 score was moderate in 9.6% and severe in 2.0%. The EPDS was moderate in 21.5% and severe in 32.9%. The IES-R was moderate in 10.3% and severe in 3.9%. Mental health impairment was reported in 37.0%. The association between the risk of mental health impairment and foreign nationality was significant (OR = 1.48; 95%CI [1.06-2.05]) as well as fetal and pregnancy worries because of coronavirus (OR = 1.46; 95% CI [1.08-1.98]) and 1.65; 95% CI [1.22-2.24]). Adjusted ORs were significant for foreign nationality (aOR = 1.51; 95%CI [1.07-2.13]) and pregnancy worries because of coronavirus (aOR = 1.62; 95%CI [1.10-2.40]). Pregnant people and especially foreign national have a high risk of mental health impairment during the pandemic.
