Feasibility and acceptability of using the Alarm Distress BaBy (ADBB) scale within universal health visiting practice in England: a mixed-methods study protocol

INTRODUCTION

The Alarm Distress BaBy (ADBB) scale developed by Guedeney and Fermanian in 2001, is a validated screening tool designed for use by healthcare practitioners to identify infant social withdrawal. This study will explore the acceptability and feasibility of the use of the full ADBB scale and a modified ADBB (m-ADBB) scale as part of routine health visiting visits in England.

METHODS AND ANALYSIS

A mixed methods sequential exploratory design will be used. Five health visitors will be trained in using the ADBB scale and 20 in the m-ADBB scale, from two National Health Service sites in England. Qualitative semi-structured interviews will be carried out with health visitors after they receive the training and again 2 months after using the scales in routine family health visits. Quantitative data will also be collected from the same participants for a range of items during the study period. The theoretical framework of Normalisation Process Theory will underpin the study, to provide in-depth explanations of the implementation process. Qualitative data will be analysed using thematic analysis. Quantitative data will be analysed using descriptive analysis.

ETHICS AND DISSEMINATION

Ethical approval was granted by the University of Oxford Departmental Research Ethics Committee. Dissemination of results will be via organisational websites, social media platforms, newsletters, professional networks, conferences and journal articles.

Social Determinants and Prevalence of Antenatal Depression among Women in Rural Bangladesh: A Cross-Sectional Study

The prevalence of antenatal depression in Bangladesh ranges from 18 to 33%. Antenatal depression has negative impacts on the mother and child such as suicidal ideations, low birth weight, and impaired fetal development. This cross-sectional study aims to determine the prevalence and social determinants of antenatal depression in rural Sylhet, Bangladesh. Data were collected from 235 pregnant women between March and November 2021. The validated Bangla Edinburgh Postnatal Depression Scale was used to measure antenatal depressive symptoms (ADS). Background information was collected using a structured questionnaire including the Duke Social Support and Stress Scale, pregnancy choices, and WHO Intimate Partner Violence questions. Point-prevalence of antenatal depression was 56%. Intimate partner violence (IPV) before pregnancy (adjusted odds ratio (AOR) 10.4 [95% confidence interval (CI) 2.7-39.7]) and perceived husband's male gender preference (AOR 9.9 [95% CI 1.6-59.6]) were significantly associated with increased odds of ADS among pregnant women. Increased family support was a significant protective factor for ADS (AOR 0.94 [95% CI 0.91-0.97]). Antenatal depression commonly occurs in rural Sylhet, Bangladesh, highlighting the need for improved screening and management within these settings. The findings suggest the need for community-based interventions for women with low family support and experiencing intimate partner violence, and educational programs and gender policies to tackle gender inequalities.

Perceptions and attitudes around perinatal mental health in Bangladesh, India and Pakistan: a systematic review of qualitative data

BACKGROUND

Perinatal mental health (PMH) is a worldwide public health issue crossing cultural boundaries. However, the prevalence of PMH conditions vary considerably. These disparities stem in part from poor understanding and stigma surrounding PMH which hinder pregnant women from seeking mental health care and may exacerbate their conditions. Bangladesh, India and Pakistan are South Asian countries with a higher burden of PMH conditions than in the Global North-West and very different social and cultural norms around gender and mental health. The aim of this systematic review (PROSPERO Ref: CRD42020167903) was to identify, synthesise and appraise the available literature on perceptions and attitudes of perinatal (pregnant and postpartum) women, their families and healthcare providers surrounding PMH in Bangladesh, India and Pakistan.

METHODS

Five electronic databases, MEDLINE, Embase, PsycINFO, Scopus and Web of science, and grey literature were searched using predefined search terms. Qualitative or quantitative articles with a qualitative component reporting perceptions and attitudes surrounding PMH in Bangladesh, India and Pakistan were eligible for inclusion, if published in English between January 2000 and January 2021. The Critical Appraisal Skills Programme Qualitative Research Checklist and Newcastle-Ottawa Scale for cross-sectional studies were used to assess study quality. Findings were synthesised using thematic synthesis, as described by Thomas and Harden 2008.

RESULTS

Eight studies were included. Five overarching themes comprising 17 sub-categories were identified. These descriptive themes were: perceived causes of PMH, perceived symptoms of PMH, perceptions of motherhood, accessing PMH care and emotional sharing and coping strategies. Sociocultural expectations underpin many of the themes identified in this review including the importance of familial and societal causes of PMH, emphasis on physical symptoms, sacredness of motherhood, lack of awareness, stigma, shame, limited resources allocated for mental health and lack of emotional sharing.

CONCLUSIONS

There is a complex range of perceptions and attitudes around PMH which influence women's experiences and access to PMH care. These findings will inform policy and practice through targeted interventions to tackle stigmatising attitudes and increasing education and training for healthcare providers.

Social determinants of antenatal depression and anxiety among women in South Asia: A systematic review & meta-analysis

Background

Pregnancy is a time of major psychological changes making pregnant women more susceptible to depression and anxiety. Prevalence is higher among women living in Bangladesh, India and Pakistan, compared to high-income countries, due to poor understanding and lack of mental health integration within antenatal care. Antenatal depression/anxiety is associated with adverse outcomes including postnatal depression, low birth weight and impaired fetal development. Existing systematic reviews provided only limited information on the social determinants of antenatal depression/anxiety in these South Asian countries.

Objective

This review aimed to identify, synthesise and appraise the evidence on the social determinants associated with antenatal depression and anxiety in women living in Bangladesh, India and Pakistan.

Methods

We searched five databases (MEDLINE, Embase, PsycINFO, Scopus, Web of Science) and PROSPERO. Observational studies published between 1^st January 2000 and 4^th January 2021 were included if they were in the English language, used validated tools for measuring depression/anxiety in pregnant women and reported statistical associations or raw numbers. Summary estimates were obtained using random-effects model. Heterogeneity and publication bias was measured using the I² statistic and Egger’s test, respectively. This review was registered on PROSPERO (reference: CRD42020167903).

Results

We included 34 studies (with 27,379 women). Meta-analysis of Adjusted Odds Ratios (AOR) found that Intimate partner violence (AOR 2.48, 95% CI 1.41–4.33), unplanned pregnancy (AOR 1.53, 95% CI 1.28–1.83), male gender preference (AOR 3.06, 95% CI 1.40–6.72) and poor relationship with in-laws (AOR 2.69, 95% CI 1.25–5.80) were significantly associated with antenatal depression/anxiety.

Conclusion

The review identified a complex range of social determinants of antenatal depression and anxiety in Bangladesh, India and Pakistan. Screening tools to identify pregnant women at high risk should be integrated within antenatal care to prevent adverse outcomes. Knowledge of these social determinants will inform the development of such screening tools and interventions.

Antenatal depression and anxiety and early pregnancy BMI among White British and South Asian women: retrospective analysis of data from the Born in Bradford cohort

BACKGROUND

Maternal obesity has severe physical impacts such as increased chances of pre-eclampsia and gestational diabetes. However, mental health impacts are given less attention within antenatal care. Evidence suggests that women with obesity carry increased risk of maternal depression and anxiety, however, this association is not well researched amongst South Asian women in the UK who are vulnerable to both. The aim of this study was to investigate the association between antenatal depression and anxiety and early pregnancy BMI, within and between White British and South Asian women, using data from the Born in Bradford cohort.

METHODS

Depression and anxiety were assessed using the General Health Questionnaire (GHQ); a GHQ score of > 0 for the depression subscale and > 6 for anxiety. Mother's BMI was stratified into six World Health Organisation BMI categories (underweight, recommended, overweight or obese class 1-3). To determine associations, univariate and multivariate logistic regression models (adjusting for maternal age, education, deprivation and smoking) were used.

RESULTS

There were 7824 women included (3514 White British and 4310 South Asian). South Asian women were more likely to have depression than White British (43.3% vs 36.1% p < 0.0001) and less likely to have anxiety (45.3% vs 48.4% p < 0.01). There were no significant associations between BMI and depression or anxiety in South Asian women. White British women with an overweight BMI had higher odds of anxiety compared with women with a recommended BMI (Adjusted Odds Ratio 1.25, 95% Confidence Interval 1.05-1.47). No significant associations were observed for other BMI categories. Smoking was a risk factor for antenatal depression (AOR 1.32, 95% CI 1.12-1.56; AOR 2.08, 95% CI 1.49-2.91) and anxiety (AOR 1.34, 95% CI 1.14-1.57; (AOR 2.87, 95% CI 2.02-4.07) in both White British and South Asian women, respectively.

CONCLUSIONS

Although South Asian women have a higher prevalence of depression than White women in this cohort, the known associations between maternal obesity and anxiety do not appear to be present. More studies are needed using validated depression tools for South Asian pregnant women. Mental health screening during antenatal care is important for South Asian women, with factors such as smoking considered.

Frequency-dependent top-down modulation of temporal summation by anodal transcranial direct-current stimulation of the primary motor cortex in healthy adults

BACKGROUND

Transcranial direct-current stimulation (tDCS) applied over the primary motor cortex has been shown to be effective in the treatment of a number of chronic pain conditions. However, there is a lack of understanding of the top-down analgesic mechanisms involved.

METHOD

In this study, we investigated the effects of tDCS on the facilitation of subjective sensory and pain scores using a transcutaneous electrically evoked measure of temporal summation. In this randomized, blinded, cross-over study healthy subjects received a single stimulus given at 0.9× pain threshold (pTh) over the L5 dermatome on the lateral aspect of the right leg, followed by a train of 5 stimuli given at 0.5, 1, 5 and 20 Hz before and after 20 min of sham or anodal tDCS (2 mA) applied over the primary motor cortex. Ratings of sensation and pain intensity were scored on a visual analogue scale (VAS).

RESULTS

Temporal summation leading to pain only occurred at higher frequencies (5 and 20 Hz). Sham or real tDCS had no effect over temporal summation evoked at 5 Hz; however, there was a significant analgesic effect at 20 Hz. Sham or real tDCS had no effect over acute, single stimuli-evoked responses.

CONCLUSION

These results indicate that anodal tDCS applied to the primary motor cortex preferentially modulates temporal summation induced by high-frequency electrical stimulation-induced pain. The inhibitory effects of tDCS appear to be dynamic and dependent on the degree of spinal cord excitability and may explain the higher analgesic efficacy in patients with moderate to severe chronic pain symptoms.

SIGNIFICANCE

The analgesic effects of tDCS are dependent on spinal cord excitability. This work provides insight into top-down modulation during acute pain and temporal summation. This knowledge may explain why tDCS has a higher analgesic efficacy in chronic pain patients.
