Chapter One — 1.1 Background to the Study

Over the past decade, the relationship between water, sanitation and hygiene (WASH) interventions and prevalence of non-communicable diseases has become a subject of considerable debate among scholars and industry practitioners alike, particularly within the context of Osun State where operating conditions differ markedly from more developed markets.

Osun State presents a useful setting for examining this relationship precisely because the conditions there — structural, regulatory, and behavioural — differ from those typically assumed in the broader literature, most of which draws on evidence from more developed economies.

1.2 Statement of the Problem

While water, sanitation and hygiene (WASH) interventions is widely discussed in policy and industry circles, empirical evidence on its actual effect on prevalence of non-communicable diseases within Osun State remains sparse and, in places, contradictory. This lack of localized, rigorous evidence makes it difficult for decision-makers to know with confidence whether current approaches to water, sanitation and hygiene (WASH) interventions are helping or hindering prevalence of non-communicable diseases — a gap this study sets out to close.

1.3 Objectives of the Study

1. To examine the effect of Water, Sanitation and Hygiene (WASH) Interventions on prevalence of non-communicable diseases in Osun State.
2. To assess the extent to which water, sanitation and hygiene (WASH) interventions influences prevalence of non-communicable diseases within the study area.
3. To identify the challenges associated with water, sanitation and hygiene (WASH) interventions in relation to prevalence of non-communicable diseases.
4. To recommend strategies for optimizing water, sanitation and hygiene (WASH) interventions in order to improve prevalence of non-communicable diseases.

1.4 Research Questions

1. What is the effect of water, sanitation and hygiene (WASH) interventions on prevalence of non-communicable diseases in Osun State?
2. To what extent does water, sanitation and hygiene (WASH) interventions influence prevalence of non-communicable diseases within the study area?
3. What challenges are associated with water, sanitation and hygiene (WASH) interventions in relation to prevalence of non-communicable diseases?
4. What strategies can be adopted to optimize water, sanitation and hygiene (WASH) interventions in order to improve prevalence of non-communicable diseases?

1.5 Significance of the Study

Beyond its academic contribution to the field of public health, this study has practical value for management teams within Osun State seeking to understand how water, sanitation and hygiene (WASH) interventions translates into measurable outcomes around prevalence of non-communicable diseases. It is equally useful to students and future researchers looking for a localized empirical reference on this relationship.

1.6 Scope of the Study

The study is limited to an examination of Water, Sanitation and Hygiene (WASH) Interventions and its relationship with prevalence of non-communicable diseases within the context of Osun State. It reflects a clearly defined scope of analysis and relies on data and perspectives available within that scope; generalizing the findings beyond this specific context should therefore be done with appropriate caution.
