Handwashing with soap is a fundamental practice for preventing communicable diseases, particularly in resource-constrained settings like Nepal, where various factors influence maternal handwashing behaviours. A systematic search encompassing PubMed/Medline, Embase, PsycINFO, CINAHL and grey literature source was conducted. Extracted eligible articles underwent descriptive analysis and their quality assessment was carried out following STROBE guidelines. From the initial screening of 187 database articles and 18 from grey literature, a total of 120 full text articles and records were retrieved to evaluated for inclusion in the review, identifying nine articles meeting the inclusion criteria for the review. Maternal handwashing with soap frequencies varied during critical moments ranging from 6% to 100%, and a 47% availability of soap and water at the household level was reported. Factors influencing handwashing included education, wealth, ecology, and participation in health promotion campaigns. Barriers included knowledge gaps, contrary beliefs, unavailability of soap and water, financial constraints, maternal demotivation, and low participation in decision-making. Limitations include study design heterogeneity (cross-sectional, Randomized Controlled Trials-RCT, Cohort), sample size variability, and geographical bias, potentially limiting generalizability of this study, limited reporting on soap and water availability for mothers at the household level is noted, and temporal variability introduces study inconsistency. Availability of soap, water, and effective health education is crucial for promoting sustained handwashing practices. Community-based interventions involving mothers in decision making and policy initiatives are essential for overcoming barriers and promote behavioural change to improve public health outcomes. This paper aims to determine the rates of handwashing with soap among mothers in Nepalese households and explore the factors associated with the uptake of handwashing. [ABSTRACT FROM AUTHOR]

Behaviour change is central to the prevention of many population health problems, yet it is typically difficult to initiate and sustain. This paper reports on an evaluation of a water, sanitation and hygiene (WASH) intervention in mid-western Nepal, with particular focus on the drivers and barriers for handwashing with soap/ash and elimination of open defecation. The research was conducted during October–November 2014, two and half years following the intervention’s end-point. Qualitative data were collected from the target community (n = 112) via group discussions, interviews and drawings/stories of ‘most significant change’. Households’ handwashing/water facilities and toilets were observed. Analysis was informed by a model that highlights environmental, psychosocial and technological factors that shape hygiene behaviours across multiple levels, from the habitual to the structural (Dreibelbis et al. 2013). Findings indicate the intervention has supported development of new norms around hygiene behaviours. Key drivers of sustained hygiene behaviour were habit formation, emotional drivers (e.g. disgust, affiliation), and collective action and civic pride; key constraints included water scarcity and socio-economic disadvantage. Identifying and responding to the drivers and constraints of hygiene behaviour change in specific contexts is critical to sustained behaviour change and population health impact.
