Purpose: This study aimed to identify socioeconomic clusters of older adults and compare cardiovascular healthamong the identified clusters.
Methods: A secondary analysis was performed using the data from 3,303 older adults(over 65 years of age; 56.5% women) who participated in the Korean National Health and Nutrition Examination Survey(2016~2017). A two-step cluster analysis was used to identify older adults’ socioeconomic clusters based on 11 factorsassociated with Socioeconomic Status (SES). Differences in the cardiovascular health outcomes among the identifiedclusters were analyzed using the x2 test and one-way ANOVA.
Results: A three-cluster solution was selected (p<.001)composed of low (n=715), middle (n=1,425), and high-SES clusters (n=1,163). The three clusters differed significantlyin the prevalence of diabetes (p<.010), hypertension (p<.001), and metabolic syndrome (p<.001), with greaterprevalence in the lower SES clusters. Similarly, systolic blood pressure (p<.001), body mass index (p<.010), andtotal cholesterol (p<.010) differed significantly among the clusters in the same pattern.
Conclusion: Older adults oflower SES clusters should be a crucial target group for health promotion interventions aimed at the prevention andmanagement of cardiovascular disease risk factors. Tailored interventions can be developed by understandingintersecting SES risk factors in this group.
