Influence of social factors on adoption of sanitation practices in rural areas: a mixed methods study in Nzaui, Kenya

INTRODUCTION: provision of adequate sanitation is among the common strategies of preventing sanitation-related diseases. However, provision of sanitation facilities may only be a sustainable solution if the population´s behavior changes and positive perception is embraced. This paper highlights the influence of social factors on adoption of sanitation practices. METHODS: convergent mixed methods design was employed. Quantitative data was gathered using structured questionnaires from 100 household heads selected using cluster and simple random techniques. Logistic regression analysis was performed to explore factors that influenced adoption of sanitation practices. Qualitative data was gathered from a purposively selected focus group and analyzed thematically. RESULTS: many (57%) of the participants were males. The average age for participants was 39 years, standard deviation (SD)=0.20. From the multivariable regression analysis with adjusted odds, household heads being aged 18-33 years (OR 1.76, 95% CI: 0.62-3.02, p=0.015) and safety of latrines (OR 1.72, 95% CI: 0.70-5.15, p<0.001) was associated with increased open defecation chances; whereas being a female (OR 0.16 95% CI: 0.06-1.81, P=0.01), availability of open spaces near households (OR 0.12, 95% CI: 0.05-1.13, p=0.30), and mason skills (OR 0.29, 95% CI: 0.13-1.65) were associated with reduced likelihood of open defecation practices. Further, being a female (OR 1.06, 95% CI: 0.18-3.16, p=0.043), having knowledge on safe sanitation (OR 1.01, 95% CI: 0.74-3.08, p=0.02), engaging skilled masons for toilet construction (OR 1.299, 95% CI: 1.01-8.95, p=0.005) and financial stability (OR 1.95, 95% CI: 0.98-23.40, P=0.032<0.001) were positively associated with adoption of improved toilets. CONCLUSION: the sanitation status in the study area was mainly poor due to the influence of multiple factors like gender, absence of toilets, knowledge on safe sanitation, poverty, mason skills and toilet location in relation to safety. The findings showed the need for innovative planning approaches based on the social aspects of communities for progress in sanitation standards in rural areas. Such approaches should adhere to the sanitation hardware versus software components of communities to promote active utilization of the available toilets, construction of improved toilets and reduction of open defecation.
