A Comparative Study of Household Water, Sanitation and Hygiene (WASH) Covariates Across Socioeconomic Strata

Abstract

Background: Water, sanitation, and hygiene (WASH) are essential for a healthy and productive life. High-quality access to these services reduces disease occurrence and spread in communities. Developing countries, including Pakistan, face significant challenges in providing these facilities. This study aims to highlight WASH-related service disparities in Pakistani households based on socioeconomic strata. Methodology: A stratified random sampling strategy was used, with a sample size of 1200 households based on the PDHS 2019 special survey. Descriptive analysis and chi-square tests were conducted to assess the association between wealth quintiles and WASH access. Results: The study found that 82.4% of households had access to improved sources of drinking water. Only 4.8% of households in the lowest quintile had access to improved drinking water sources. Water unavailability for at least one day per week was 13% higher among the lower quintiles. Forty-four percent of households using improved sanitation facilities belonged to the two highest strata, while poorer households predominantly used unimproved sanitation facilities. Conclusion: Lower-quality WASH access is more prevalent among lower wealth quintiles, increasing the risk of disease and infection. Further research is needed to inform policymakers and develop plans to reduce inequalities in access to WASH services.
