Child undernutrition is linked to substantial national economic and health losses in low- and middle-income countries, including Rwanda. Although the causal and contextual factors contributing to chronic malnutrition in children in Rwanda have been explored, the role of the mothers’ mental health has not been fully investigated. This study aims to determine the prevalence of major depressive disorders, generalised anxiety and suicide risk among mothers in Rwanda and to explore their association with child stunting.

This study used a cross-sectional, population-based design.

Participants included children aged 1–36 months (n=601) and their mothers (n=601) in Rwanda’s Northern Province. Mothers’ mental health was assessed using four modules from the Mini International Neuropsychiatric Interview, based on the Diagnostic and Statistical Manual of Mental Disorders. Child anthropometric measurements followed WHO guidelines.

The primary outcome of the study was child stunting that was defined as a height-for-age Z (HAZ) score

Among the 601 mothers assessed, generalised anxiety disorder had the highest prevalence (36.6%), followed by recurrent major depressive disorder (27.3%), current major depressive disorder (22.7%) and current suicide risk (18.2%). Among the children, 27.1% were stunted, with prevalence rising from 9.8% in infants (1–12 months) to 39.9% in toddlers (25–36 months). Current major depressive disorders in mothers were associated with child stunting (adjusted OR 1.67; 95% CI 1.06 to 2.61). Affected children had lower HAZ scores (–1.68±1.36 vs –1.30±1.09; p=0.004), and excess relative risk (ERR) analysis confirmed depression as a significant risk factor (ERR: 1.56; p=0.005).

Mental health disorders in mothers, especially depression, showed a significant association with child stunting. Addressing mental health disorders in mothers is essential for improving child nutritional outcomes.

Despite an increasing amount of research related to gender-affirming treatment (GAT) outcomes among transgender and gender-diverse (TGD) people (ie, people who experience discomfort or distress in the misalignment between their gender and sex assigned at birth) in recent years, the evidence base for current recommendations is suboptimal. One contributing factor is the heterogeneity in the outcomes and outcome measures used. This study seeks to address this challenge by developing a foundational core outcome set (COS) to be used for TGD adults receiving GAT in Sweden.

Recommendations from the Core Outcome Measures in Effectiveness Trials initiative will be used to address this aim in four phases. Phase 1, an umbrella review of peer-reviewed literature and international guidelines in GAT will be conducted to identify relevant outcomes. In phase 2, we will solicit input from TGD individuals through the review of patient and interest organisations’ reports and an anonymous survey to identify outcomes of personal significance. In phase 3, using the Delphi method, 2–3 rounds of assessment will be conducted where researchers, healthcare professionals, policy-makers and TGD adults rate the identified outcomes by perceived importance. In phase 4, a consensus meeting will convene representatives from all stakeholder groups to finalise the COS.

The results of this study will consist of a COS for GAT regarding TGD adults in Sweden. Participant survey responses will be evaluated using interpretive analysis to identify core outcomes. During each of the Delphi rounds, Likert-type scale ratings will be aggregated for outcomes to advance or be eliminated in each round.

The study has received ethical approval by the Swedish Ethical Review Authority (Umeå medicine department, Registration number: 2024-04672-01). The results of this study will be published open-access and disseminated through TGD interest organisations and a Swedish research network for gender dysphoria.
