Despite improvements in WASH services in Bangladesh, consistent hygiene practices and equitable access to WASH facilities remained challenging in disaster prone char areas. The JAMUNA Project implemented by Bangladesh Red Crescent Society aimed to improve WASH conditions and hygiene practices in vulnerable populations of Sariakandi Upazila, Bogura District. Objectives: To explore accessibility, adoption and accessibility of hygiene related WASH interventions and their influences on hygiene practices at the community level. Methods: A concurrent mixed-methods implementation research study was conducted in two unions of Sariakandi Upazila covered by the JAMUNA Project using CFIR framework. The study population included adult married men and women for the quantitative survey, and adult beneficiaries who had received WASH infrastructure support or were exposed to WASH interventions for the qualitative component. The sample size for the quantitative data collection was 85 participants, while qualitative data were collected through 8 IDI and 2 FGDs. Systematic random sampling method was applied for the survey data collection while purposive sampling was used for the qualitative data collection. The analysis was conducted using STATA MP 17.0 version for the quantitative and qualitative data were analyzed using framework thematic analysis. Results: Most households had access to improved sanitation facilities and improved water sources. However, inconsistent handwashing with soap at key times was observed. Handwashing after toilet use was more commonly practiced than before food preparation and eating. Access to a tube well did not ensure the presence of a functional handwashing facility. tationted space was identified as a main barrier to establishing handwashing facilities and participants described perception of maintaining the presence of soap and water availability at the facilities. Several households reported soap inside the latrine and soap availability at the handwashing facilities which facilitated handwashing practices. Practical demonstrations during courtyard sessions were identified as a facilitator for improving handwashing behaviours. In contrast, financial constraints such as initial procurement costs for latrine construction materials and delayed reimbursement were identified as key barriers, particularly among household with poor income. Conclusions: The study found high reported access WASH facilities and variable hygiene practices in the study areas. The JAMUNA Project interventions were perceived to support hygiene related practices, although gaps in consistent handwashing practices and access to basic handwashing facilities remained limited. The provision of soap or promotion of soap availability based on the community perceptions and existing practices, should be incorporated in future implementation. The reimbursement process should be revised to better reach the households with low income.61 pagesen-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalBRAC University theses are protected by copyright.
