Objectives Adequate physical activity is essential for promoting healthy life expectancy among older adults. Park accessibility is an important environmental determinant of physical activity and may support multimorbidity management in this population. However, evidence on the association between park accessibility and multimorbidity remains limited, particularly in nationally representative Korean samples. This study examined the association between park accessibility and multimorbidity among older Korean adults.
Methods This cross-sectional study analyzed data from 10,078 individuals aged ≥65 years who participated in the 2023 National Survey of Older Koreans. Multiple logistic regression was used to examine the association between park accessibility and multimorbidity after adjustment for covariates. Stratified analyses assessed this association by physical activity level, and additional logistic regression analyses evaluated associations between park accessibility and common chronic diseases.
Results The prevalence of multimorbidity among older adults was 64.8%. After adjustment for all covariates, older adults living 30–59 minutes’ walking distance from a park had higher odds of multimorbidity than those living <15 minutes from a park (adjusted odds ratio, 1.33; 95% confidence interval, 1.12–1.59). Among the common chronic diseases examined, hypertension was significantly associated with park accessibility.
Conclusion Greater park accessibility may support physical activity and green-space exposure and may thereby contribute to multimorbidity management and healthy life expectancy among older adults.

<title>Objectives</title>
<p>The aim of this study was to investigate comorbidities in patients with end-stage renal disease, and to compare health-related quality of life (HRQOL) according to the type, and number of comorbidities.</p></sec>
<sec>
<title>Methods</title>
<p>A total of 250 adults undergoing hemodialysis were recruited at local clinics. HRQOL was measured using the 12-item Medical Outcomes Study Short Form questionnaire. Data were analyzed using descriptive statistics, analysis of variance, and <italic>t</italic> test.</p></sec>
<sec>
<title>Results</title>
<p>Around 70.8% of patients with end stage renal disease had 1 or more comorbidities, and the most common comorbidities were hypertension, diabetes, and cardiovascular disease. HRQOL was significantly different based on the number of comorbidities (F = 9.83, <italic>p</italic> < 0.001). The effect of comorbidities on the scores for mental health domains of the HRQOL questionnaire was not conclusive compared with the scores for the physical domain which were conclusive. Among the comorbidities, diabetes was associated with a lower quality of life.</p></sec>
<sec>
<title>Conclusion</title>
<p>The customized management of diabetic and hypertensive patients is necessary for the early detection and prevention of chronic kidney disease, and slowing the progression of renal disease and managing cardiovascular risk factors is essential.</p></sec>
