Parents of children with neurodevelopmental disorders often experience high levels of stress that impact their mental health, yet few interventions focus on their well-being. To address this gap, we developed a mental health intervention based on emotional intelligence (EI), designed for delivery in healthcare settings. We hypothesise that enhancing EI can reduce parenting stress and improve psychological well-being. This study aims to assess the effectiveness, cost-effectiveness and feasibility of this EI-based intervention in Bangladesh.

This hybrid type 1 effectiveness-implementation study will include a cluster randomised controlled trial, an implementation analysis and an economic evaluation. Eight child development centres will be randomly assigned in a 1:1 ratio to intervention and waitlist control groups. A total of 480 parents (mothers and fathers) will be recruited. The intervention consists of interactive sessions on EI skills, supported by personal diaries and a mobile app. Data will be collected at baseline and 12 weeks postintervention using validated tools to assess EI, parenting stress, psychological well-being and other mental health outcomes. Implementation will be evaluated using mixed methods to assess feasibility, acceptability and fidelity. Cost-effectiveness will be determined through a cost–utility analysis of direct and indirect costs.

Ethical approval was granted by the Institutional Review Board of Bangladesh Medical University (BSMMU/2022/10733). Written informed consent will be obtained at each stage of data collection and intervention. Findings will be disseminated through open-access publications, plain-language summaries, academic conferences, community workshops and policy briefs. Data will be shared in open-access platforms to inform mental health strategies in low-resource settings globally.

In Bangladesh, evidence on the long-term trajectory of adolescents' sexual and reproductive health (SRH) remains limited, largely due to the lack of longitudinal data to assess the changes over time. To address this gap, the Advancing Sexual and Reproductive Health and Rights (AdSEARCH) project of International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) set up an adolescent cohort study aimed at documenting changes in SRH knowledge, attitudes and practices, and identifying the factors affecting these changes. This article presents the baseline sociodemographic and SRH characteristics of this cohort as a pathway for future analyses.

This cohort study included 2713 adolescents from the Baliakandi Health and Demographic Surveillance System run by icddr,b. The cohort covered three age groups from girls and boys, giving a total of five cohorts: girls aged 12, 14 and 16 years; and boys aged 14 and 16 years. A total of seven rounds of data had been collected at 4-month intervals over 2-years follow-up period.

The majority of adolescents were attending school (90%), and school dropouts were higher among boys. Around 17% of the respondents were involved in income-generating activities, which were mostly boys. Among girls, the mean age of menarche was 12.2 years. Overall, 6% of adolescents had major depressive disorder, with prevalence increasing with age. Gender differences were evident regarding knowledge about conception and contraception. Egalitarian attitudes towards social norms and gender roles were found higher among girls (52%) compared to boys (11%). The majority of adolescents reported experiencing social/verbal bullying (43%), followed by physical violence (38%) and cyberbullying (4%).

This article presents the baseline findings only. A series of papers is in the pipeline for submission to different peer-reviewed journals. The findings from this study will be used to support data-driven policy formulation for future adolescent health programmes.

The aim of this study was to analyse associations between crowded housing and children’s indoor living environment, respiratory and allergic disorders and general health.

A cross-sectional study.

Sweden, using data from the Swedish National Environmental Health Survey 2019.

The study sample included 48 512 children (aged 6–10 months, 4 years and 12 years). We also investigated associations in vulnerable subgroups, such as children with asthma and those living under unfavourable socioeconomic conditions.

Primary outcomes in the living environment were at least one sign of mould, poor indoor air quality, unpleasant odours, too warm indoors in summer and too cold indoors in winter. Primary outcomes for children’s health were asthma, airway problems, breathing difficulties, rhinitis symptoms, mould and mites allergy, pollen allergy, furred pet allergy and good general health.

About one in five children lived in an overcrowded home. Factors from the indoor living environment such as perceived poor indoor air quality and mould were significantly associated with crowded housing. Moreover, children who lived in overcrowded conditions were less likely to report good general health than children in non-crowded households (OR 0.64, 95% CI 0.54 to 0.76). This association was even stronger in children with asthma (OR 0.51, 95% CI 0.34 to 0.77). Few significant associations were, however, observed with the respiratory and allergic health outcomes.

Crowded housing is associated both with a poor indoor environment and with poorer general health in children. Children with asthma may experience even poorer general health.

Research indicates the effectiveness of participatory interventions to address rapid rises in type 2 diabetes in low-income countries. Understanding their transferability to different contexts is a priority. We aimed to analyse how the COVID-19 post-lockdown context and adjustments to a participatory learning and action intervention affected theorised mechanisms of effect in rural Bangladesh and to examine the broader implications of this context and intervention adjustments for developing optimal contexts for participatory interventions.

Mixed methods using longitudinal qualitative and quantitative observation data, focus group discussions and interviews with group and community members and project personnel. We used descriptive content analysis, guided by realist evaluation research questions about context, implementation and mechanisms. We used team reflection to enhance the rigour of our analysis.

Cluster-randomised trial in Alfadanga upazila, Faridpur district, in the central region of Bangladesh. The intervention was implemented between January 2020 and December 2022, during the COVID-19 pandemic.

Participatory group members, community members and project personnel (n=32). Structured observations of participatory groups (n=1820) and unstructured observations of groups and their environments (n=15).

Participatory learning and action community groups of men and women implemented by community-based facilitators.

Due to COVID-19, the participatory learning and action (PLA) intervention was not implemented as planned, which had major effects on the time available to develop the intervention with communities. Communities learnt about diabetes and were motivated to address its causes at an individual level, but community action was a more challenging mechanism to trigger. The post-pandemic context made it difficult to build community rapport, and strategies to engage communities through home visits were challenging. Communities’ prior negative experience in working together and in working with non-governmental organisations led to low community cohesion and low motivation to address diabetes collectively. This also resulted in expectations that the implementing organisation would implement community actions and incentivise attendance at meetings. This misalignment of expectations further disabled relationship building, and community strategies addressing the social causes of diabetes were largely not enacted.

PLA has optimal effects when time is available to build trust and social cohesion. These are contextual elements and mechanisms that need to be activated to enable critical reflection and community action to develop an enabling environment to address type 2 diabetes.
