In Africa, 75% of households are exposed to household air pollution (HAP), a key contributor to cardiovascular disease (CVD). In Nigeria, 90 million households rely on solid fuels for cooking, and 40% of adults have hypertension. Though clean fuel and clean stove (CF-CS) technologies can reduce HAP and CVD risk, their adoption in Africa remains limited.

Using the Exploration, Preparation, Implementation and Sustainment framework, this cluster-randomised controlled trial evaluates the implementation and effectiveness of a community mobilisation (CM) strategy versus a self-directed condition (i.e., receipt of information on CF-CS use without CM) on adoption of CF-CS technologies and systolic blood pressure (SBP) reduction among 1248 adults from 624 households across 32 peri-urban communities in Lagos, Nigeria. The primary outcome is CF-CS adoption at 12 months; secondary outcomes are SBP reduction at 12 months and sustainability of CF-CS use at 24 months. Adoption is assessed via objective monitoring of stove usage with temperature-triggered iButton sensors. SBP is assessed in 2 adults per household using validated automated blood pressure monitor. Generalised linear mixed-effects regression models will be used to assess study outcomes, accounting for clustering at the level of the peri-urban communities (unit of randomisation) and households. To date, randomisation is completed, and a total of 1248 households have enrolled in the study. The final completion of the study is expected in June 2026.

The study was approved by the Institutional Review Boards (IRB) of NYU Grossman School of Medicine (primary IRB of record; protocol ID: i21-00586; Version 6.0 approved on 4 June 2024), and Lagos State University Teaching Hospital (protocol ID: LREC 06/10/1621). Written consent was obtained from all participants. Findings will inform scalable and culturally appropriate strategies for reducing HAP and CVD risk in low-resource settings. Results will be disseminated through peer-reviewed publications, conference presentations and stakeholder engagements.

All those born with functioning ovaries will eventually experience menopause, and many will be symptomatic. However, significant gaps in the evidence base for menopause care remain. This National Institute for Health and Care Research James Lind Alliance Menopause Priority Setting Partnership (MAPS) will engage with clinicians and those with lived experience globally to determine the leading priorities for future menopause research.

MAPS will follow the established James Lind Alliance methodology which has already resulted in over 100 ‘top 10’ research priorities across health domains. It will be led by a steering group comprised of clinicians and lived experience members. Leveraging the networks of steering group members and partner organisations, the priority setting partnership will identify evidence uncertainties using an online survey. Evidence checking will be undertaken to determine which questions have already been answered. Prioritisation will be done in two stages, initially by online survey and then at a face-to-face workshop.

Ethical approval was not required. The final top 10 priorities for menopause, as ranked by stakeholders at the final consensus workshop, will be disseminated in the relevant peer-reviewed journals. A final report will be available on the MAPS and James Lind Alliance websites. The leading priorities will inform the future global research agenda for menopause.
