The COVID-19 pandemic has inhibited people's help-seeking behaviors (HSBs). In particular, older people in rural communities experienced limited access to medical care, which negatively affected their quality of life (QOL). Within HSB, self-management of mild symptoms may mitigate the difficulties experienced by older people in rural communities. However, few studies have examined the relationship between self-management and QOL. Therefore, we conducted a prospective cohort study to clarify this relationship. Our participants were over 65 years of age and lived in rural communities. QOL was measured with the EuroQol 5-Dimension 5-Level (EQ-5D-5L). Demographic data and QOL were collected from participants via questionnaires in 2021 and 2022. The exposure group showed a significantly greater change in EQ-5D-5L health status index scores than the control group (p = 0.002). In addition, the exposure group scored significantly lower than the control group on the EQ-5D-5L dimension "usual activities" in 2021 and on all dimensions in 2022. Thus, self-management of mild symptoms may improve QOL among older people in rural communities during the COVID-19 pandemic. Educational interventions for this population regarding self-management could improve QOL for entire communities.
