Community Mobilization for Improved Clean Cookstove Uptake, Household Air Pollution Reduction, and Hypertension Prevention

Using a focused implementation research framework, the EPIS (Exploration, Preparation, Implementation and Sustainment) model in a type-2 hybrid design, the study will be conducted in 3 phases: 1) A pre-implementation phase that will use the Exploration and Preparation domains of EPIS to: a) explore barriers and facilitators of Clean Fuel- Clean- Stove (CF-CS) use, and b) develop a culturally-tailored CM strategy for CF-CS use; 2) An Implementation phase that will use the Implementation domain of EPIS to compare in a cluster RCT of 32 peri-urban communities (640 households), the effect of CM vs. a self-directed condition (i.e. receipt of information on CF-CS use without CM) on adoption of CF-CS use; and systolic BP reduction; 3) A post-implementation phase that will use the Sustainment domain of EPIS to evaluate the effect of CM strategy vs. self-directed condition on sustainability of the CF-CS use in 640 households across the randomly assigned 32 peri-urban communities in Nigeria. The Lagos State University College of Medicine (LASUCOM) working with the MOH will oversee research coordination in Nigeria.

About this study

This study will use CM to engage in the community dialogues, organize outreach facilitation, and advocacy for the adoption of bioethanol-based and liquified petroleum gas (LPG) CF-CS across participating households. The choice of CM strategy is deliberate because, unlike western culture, African cultures are largely based on communal hierarchy.

Treatment and study plan

Community Mobilization

Behavioral

The Community Mobilization (CM) strategy will include: (1) Community advisory board [comprising local community-based organizations, government officials, and residents], that will provide leadership support and buy-in for adoption of Clean Fuel- Clean- Stove (CF-CS) use; (2) Trained MoH community health extension workers, community health officers, community mobilizers and health education officers, who will form community action teams (CAT) to facilitate the implementation of CF-CS use via provision of support, knowledge exchange and performance feedback to the primary cooks in participating households; (3) Community dialogues with residents and households focused on shared concerns on the significance and importance of CF-CS use.

Primary outcomes

  1. Percent of Households Who Have Adopted CF-CS at Baseline

    Time frame: Baseline

    Adoption defined as utilization of the CF-CS for more than 50% of cooking activities based on the metric developed by the Global Alliance for Clean Cookstoves. All traditional stoves and the bioethanol-based CF-CS in the participating households will be equipped with the iButtons SUMs to assess their use. Trained study staff will collect iButton temperature data during household visits.

  2. Percent of Households That Have Adopted CF-CS at Month 12

    Time frame: Month 12

    Adoption defined as utilization of the CF-CS for more than 50% of cooking activities based on the metric developed by the Global Alliance for Clean Cookstoves. All traditional stoves and the bioethanol-based CF-CS in the participating households will be equipped with the iButtons SUMs to assess their use. Trained study staff will collect iButton temperature data during household visits.

Secondary outcomes

  1. Change in Mean Systolic Blood Pressure From Baseline to Month 12

    Time frame: Baseline, Month 12

    Blood pressure readings assessed with a validated automated BP device. At each visit, three readings will be taken by trained research coordinators using an automated BP monitor. The average of three BP readings will be used as the measure for each study visit.

  2. Percent of Participants Who Have Adopted CF-CS at Month 24

    Time frame: Month 24

    Measure of sustainability. Adoption defined as utilization of the CF-CS for more than 50% of cooking activities based on the metric developed by the Global Alliance for Clean Cookstoves. All traditional stoves and the bioethanol-based CF-CS in the participating households will be equipped with the iButtons SUMs to assess their use. Trained study staff will collect iButton temperature data during household visits.
