Bangladesh is highly prone to recurrent flooding that disrupts all four pillars of food security. This study aimed to explore the effect of household food insecurity on the underweight status of women in flood-affected areas of Bangladesh, which remains underexplored.

This is a cross-sectional analysis.

This study was conducted in eight sub-districts (upazilas) across eight districts in Bangladesh that experience severe to moderate river flooding, flash floods and substantial tidal surges.

A total of 532 women participated in the study. The inclusion criteria for participation were as follows: (1) being at least 18 years of age, (2) residing in the household for at least 1 year and (3) having experienced limited food access in the 4 weeks before data collection due to flood-related constraints.

Household food insecurity was measured using the U.S. Agency for International Development Household Food Insecurity Access Scale questionnaire. An underweight status was evaluated through anthropometric measurements of women. Adjusted prevalence ratios (aPRs) were estimated using robust log-linear models.

Moderate food insecurity was the most common (58.3%) among the participants. The prevalence of underweight was the highest (52.1%) in the severely food-insecure group and decreased significantly with improved food security. Severe household food insecurity was strongly associated with a higher prevalence of underweight individuals (aPR = 4.12; 95% CI, 1.60 to 10.60). An underweight status was also prevalent in women from moderately food-insecure households (aPR = 1.75; 95% CI, 0.68 to 4.55).

This study reveals a significant association between household food insecurity and underweight status, highlighting the major challenges faced by women living in flood-prone areas of Bangladesh. These findings emphasise the urgent need to address household food insecurity to improve nutritional outcomes for women in vulnerable communities.

Despite a high disease burden, care-seeking for mental health symptoms is low in Bangladesh, particularly among women.

To evaluate help-seeking behaviours for anxiety and depression symptoms among Bangladeshi women aged 15–49 and its association with women’s empowerment.

Data from the Bangladesh Demographic and Health Survey 2022 including 2881 women reporting anxiety or depression symptoms were analysed. Help-seeking behaviours, sociodemographics and women’s empowerment using the Survey-based Women’s Empowerment (SWPER) index were assessed. Logistic regression models were used to explore associations.

The mean age of participants was 33.3 years (SD 8.7); two-thirds lived in rural areas. In the SWPER index, 83% of women had high empowerment in the attitude to violence domain, 16% in social independence and 60% in decision-making. Among women with anxiety or depression symptoms, 18.7% sought help, mainly from spouses (43%) or family (52%), and 15% consulted doctors. Women aged >30 years (adjusted OR, aOR 1.25, 95% CI 1.02 to 1.53), from rich households (aOR 1.49, 95% CI 1.09 to 1.89), and with secondary (aOR 1.47, 95% CI 1.08 to 2.01) or higher education (aOR 1.56, 95% CI 1.03 to 2.36) were more likely to seek help. High empowerment in attitude to violence (aOR 0.54, 95% CI 0.37 to 0.81) and decision-making (aOR 0.53, 95% CI 0.41 to 0.68) correlated negatively with help-seeking.

Few Bangladeshi women seek help for mental health symptoms, relying on informal sources. Age, education, wealth and employment predict help-seeking, while high empowerment level in attitude to violence and decision-making domain of SWPER index shows an inverse relationship.

Nipah virus (NiV) is a bat-transmitted paramyxovirus causing recurrent, high-mortality outbreaks in South and South-East Asia. As a WHO priority pathogen, efforts are underway to develop therapies like monoclonal antibodies and small-molecule antivirals, which require evaluation in clinical trials. However, trial design is challenging due to limited understanding of NiV’s clinical characteristics. Given the rarity of NiV infections, strategies targeting improved outcomes for the broader acute encephalitis syndrome (AES) patient population, including those with NiV, are essential for advancing therapeutic research. To address these gaps, we designed the Bangladesh AES cohort study to characterise the patient population, clinical features, treatment practices, common aetiologies and outcomes in patients presenting with AES, including NiV infection, as a clinical characterisation study to inform the design of clinical trials for NiV and AES more broadly.

This prospective cohort study will be conducted in Bangladesh, a NiV endemic country with annual outbreaks. In collaboration with the ongoing NiV surveillance programme in Bangladesh, we aim to enrol up to 2000 patients of all ages presenting with AES at three tertiary care hospitals within the Nipah belt. Patients who provide informed consent to participate will be monitored throughout their hospital stay until 90 days post enrolment. Data will be systematically collected through interviews and medical record reviews at several time points: on the day of enrolment, day 3, day 7, the day of critical care admission (if applicable), discharge day and 90 days post enrollment. Additionally, a portion of the cerebrospinal fluid collected under the concurrent NiV surveillance protocol will be tested for an array of viral and bacterial pathogens responsible for encephalitis at the International Centre for Diarrhoeal Disease Research Bangladesh (icddr,b) laboratory.

The study received ethical approval from the Oxford Tropical Research Ethics Committee, University of Oxford, UK (OxTREC Ref: 576–23) and the institutional review board of icddr,b, Bangladesh (icddr,b protocol number: 24016). By characterising the AES patient population, this study will generate essential evidence on key clinical parameters, which will be pivotal in optimising the design of clinical trials for potential interventions aimed at improving outcomes in patients with AES, including those with NiV disease. Findings will be shared with participating hospitals, patients and relevant government stakeholders. Results will also be disseminated through conference presentations and peer-reviewed publications.

The rising burden of non-communicable diseases (NCDs), including mental health disorders (MHDs) such as anxiety and depression, poses a significant public health challenge globally. Evidence suggests that both diabetes and hypertension, the two most prevalent NCDs, are linked to a higher prevalence of MHDs. However, there is a lack of evidence on prevalence of generalised anxiety disorder (GAD) and depression among adults living with both diabetes and hypertension in Bangladesh. We aimed to assess the prevalence of GAD and depression and explore the associated factors among adults living with diabetes and hypertension comorbidity in rural Bangladesh.

We implemented a cross-sectional study.

The study was conducted in Chirirbandar, a sub-district of Dinajpur, Bangladesh.

We interviewed a total of 387 adults living with diabetes and hypertension comorbidity.

We had two primary outcome measures: GAD and depression. Individuals scoring ≥10 on the General Anxiety Disorder-7 scale were considered as having GAD and individuals scoring ≥10 on the Patient Health Questionnaire-9 scale were considered as having depression. The outcome variables were dichotomised based on these scores.

The prevalence of GAD was 7.24% (95% CI 5.04 to 10.29). Education level (grades 5–9) (adjusted OR (AOR): 3.40, 95% CI 1.26 to 9.19) and household wealth status (highest wealth tertile) (AOR: 0.12, 95% CI 0.02 to 0.62) were associated with GAD. The prevalence of depression was 17.83% (95% CI 14.32 to 21.98). Socioeconomic factors associated with depression included unemployment (AOR: 3.26, 95% CI 1.05 to 10.10) and household wealth status (highest wealth tertile) (AOR: 0.45, 95% CI 0.21 to 0.98). Higher odds of depression were also observed among participants with controlled hypertension (AOR: 3.88, 95% CI 1.81 to 8.35). Other factors, such as tobacco use, dietary diversity and physical activity, were not associated with GAD or depression.

A high prevalence of GAD and depression was observed among adults living with diabetes and hypertension comorbidity. The findings from the study emphasise the need for integration of mental health services into the existing non-communicable disease care. The identified factors associated with GAD or depression should be considered to develop targeted interventions for people with hypertension and diabetes comorbidity in Bangladesh.

Selecting an optimal initial dosage of opioid agonist treatment (OAT) balances effectiveness and safety, as initial doses that are too low may be insufficient, potentially prompting clients to seek unregulated drugs to alleviate withdrawal symptoms, which may increase the likelihood of treatment discontinuation. Conversely, initial doses that are too high carry a risk of overdose. As opioid tolerance levels have risen in the fentanyl era, linked population-level data capturing initial doses in the real world provide a valuable opportunity to refine existing guidance on optimal OAT dosing at treatment initiation. Our objective is to determine the comparative effectiveness of alternative initial doses of methadone, buprenorphine-naloxone and slow-release oral morphine at OAT initiation, as observed in clinical practice in British Columbia (BC), Canada.

We propose a population-level retrospective observational study with a linkage of nine provincial health administrative databases in BC, Canada (1 January 2010 to 31 December 2022). Our study includes two time-to-event primary outcomes: OAT discontinuation and all-cause mortality during follow-up. We propose ‘initiator’ target trial analyses for each medication using both propensity score weighting and instrumental variable analyses to compare the effect of different initial OAT doses on the hazard of time-to-OAT discontinuation and all-cause mortality. A range of sensitivity analyses will be used to assess the robustness of the results.

The protocol, cohort creation and analysis plan have been classified and approved as a quality improvement initiative by Providence Health Care Research Ethics Board and the Simon Fraser University Office of Research Ethics. Results will be disseminated to local advocacy groups and decision-makers, national and international clinical guideline developers, presented at international conferences and published in peer-reviewed journals electronically and in print.

The development of mental disorders is multifactorial across the lifespan. The introduction of the exposome concept has enhanced the understanding of life-course environmental factors by encompassing the totality of environmental exposures. While most studies on chronic diseases have applied a single-exposure approach, the exposome approach remains underutilised in mental disorder research. There is a need to better recognise the environmental factors considered in exposome analysis of mental disorders, the methodologies used and the gaps reported. This scoping review aims to map the evidence on the relationship between the exposome and mental disorders across the lifespan, identifying and describing the methodologies used and highlighting the gaps reported.

This scoping review will follow PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and the Population-Concept-Context approach. It will include observational and interventional studies involving populations of all ages in the community or healthcare settings. The search strategy will contain indexed terms in MEDLINE and will be adapted for CINAHL (EBSCO), Scopus, Embase and PsycINFO without restrictions on language or date of publication. For the selection of articles, two independent researchers will screen articles by title and abstract, followed by a full-text assessment. Afterwards, the extracted data will be summarised using a narrative and descriptive analysis.

Ethics approval is not required for this scoping review. Dissemination activities will include peer-reviewed publications and academic presentations.

The use of different electronic devices is increasing among students due to rapid advancements in digital technology. The prevalence of computer vision syndrome (CVS) has increased among school children after the COVID-19 pandemic. Different symptoms of CVS, such as eye strain, headache, blurred vision and visual discomfort, have become major public health problems. This study aimed to assess the prevalence of CVS, identify its risk factors, evaluate parental awareness and examine the impact of COVID-19 on screen time among primary school children in Dhaka, Bangladesh.

Primary data were collected from the parents of 500 primary school students aged 5–14 years using a convenience sampling method through face-to-face interviews. A structured questionnaire was administered to collect demographic information, screen usage patterns, ambient conditions and details regarding the children’s academic performance. The Computer Vision Syndrome Questionnaire scale was used to assess the prevalence and severity of CVS. Various statistical analyses were performed, including ² tests, Fisher’s exact tests and logistic regression, to identify significant predictors of CVS (p

Findings revealed that 16.4% of children were affected by CVS, with key risk factors including age, school year, maternal education and daily screen time. Children with CVS commonly reported headaches and itchy eyes, which negatively impacted their academic performance. Surprisingly, 67.4% of parents were unaware of CVS, and the odds of developing CVS were 3.74 times higher among children using electronic devices for more than 4 hours daily.

The study explored the low prevalence of CVS among primary school students in Dhaka, Bangladesh. Several symptoms, like headaches and eye discomfort, were identified that impaired their academic performance. Additionally, many parents were largely unaware of CVS. Therefore, it is necessary to take proper strategies to be aware of the consequences and lessen the prevalence of CVS to save our future generation.

Methadone and buprenorphine/naloxone are effective medications for people with opioid use disorder; however, interruptions in daily dosing are common and diminish the benefits of these medications. While clinical guidelines in most North American jurisdictions, including British Columbia (BC), recommend dose adjustment after treatment interruptions to varying levels of specificity, the evidence to support these recommendations is limited. We aim to estimate the comparative effectiveness of alternative dose adjustment strategies on subsequent overdose-related acute care visits and discontinuation of opioid agonist treatment in BC, Canada.

Using a linkage of nine health administrative databases, we propose a population-level retrospective cohort study of adults aged 18 years or older in BC who initiated methadone or buprenorphine/naloxone between 1 January 2010 and 31 December 2022. We will specify parallel hypothetical trials, known as target trials, for methadone interruptions of 1–3 days, 4 days and 5–14 days, and buprenorphine/naloxone interruptions of 1–5 days and 6–14 days. Following the index interruption, the primary outcomes are the time to overdose-related acute care visits and treatment discontinuation (interruptions lasting >14 days), with time to all-cause acute care visits as a secondary outcome. The intention-to-treat effect will be estimated using both propensity score and instrumental variable approaches. A range of sensitivity analyses will assess the robustness of our results, including cohort and timeline restriction, alternative definitions of exposure and outcome and alternative estimation strategies.

The protocol, cohort creation and analysis plan have been classified and approved as a quality improvement initiative by Providence Health Care Research Institute and the Simon Fraser University Office of Research Ethics. All data are deidentified, securely stored and accessed in accordance with provincial privacy regulations. Results will be disseminated to local advocacy groups and decision-makers, national and international clinical guideline developers, presented at international conferences and published in peer-reviewed journals electronically and in print.

Rapid urbanisation and the dense population of Bangladesh foster the growth of slum settlements, where poverty and food insecurity are magnified by economic instability and inflationary pressures, adversely affecting psychological health.

This study aimed to assess household food security and its influence on psychological well-being among adults living in urban slums of Bangladesh.

A cross-sectional study using convenient sampling was conducted among 300 adults in slums in Dhaka, Bangladesh, using a semistructured questionnaire to collect data on sociodemographics, food security and mental health status. Multivariable logistic regression analyses were conducted to observe the influence of food insecurity on mental health status, controlling for other covariates.

The majority of the participants experienced food insecurity, with 38.0% expressing severe food insecurity. High levels of psychological distress were observed, including stress (54.7%), anxiety (63.3%) and depression (73.3%). Older adults (aOR 4.5, 95% CI 1.3 to 15.5) and females (aOR 4.1, 95% CI 2.0 to 8.4) had higher odds of experiencing anxiety. Single individuals were more prone to experience depression, while homemakers exhibited elevated levels of both depression and anxiety. Furthermore, moderate to severe food insecurity was significantly associated with higher odds of depression (aOR 2.8, 95% CI 1.2 to 6.7) and anxiety (aOR 8.2, 95% CI 3.3 to 20.3) compared with no or mild food insecurity.

This study highlights the pervasive influence of household food insecurity on urban slum dwellers’ psychological well-being. Addressing vulnerabilities tied to age, marital status and occupation is crucial for alleviating mental health burdens.
