In the Environmental Domain, the sociodemographics that were moderately correlated were marital status (V = .362) and occupational status (rpb = .321). These two factors had a stronger relationship to environmental quality of life (QoL) compared to the other variables, which showed only weak correlations.

Marital status affected the Environmental Domain because having a spouse often provided emotional, financial, and practical support—such as assistance with transportation to dialysis, navigating the healthcare system, and maintaining a safe, stable home environment. Married patients tended to have better access to resources that improve environmental QoL, while single, divorced, or widowed individuals sometimes struggled with these supports, impacting their living conditions and access to care. Occupational status also influenced the Environmental Domain significantly. Employed patients benefited from better financial stability, allowing them to afford safer housing, better transportation, and necessary healthcare services. On the other hand, unemployed patients often faced financial hardships, limiting their environmental supports and worsening their ability to maintain a healthy and stable living situation.

Thus, marital and employment statuses moderately affected how CKD patients experienced their environment, while other factors like age, sex, education, income, and comorbidities had only weak effects.
