Metabolic syndrome and related factors in early-old and late-old cancer survivors

[Purpose] The purpose of this study was to examine the prevalence of, and factors associated with, metabolic syndrome in older cancer survivors by comparing early-old (65–74 years) and late-old (≥75 years) groups using nationally representative data.[Methods] A cross-sectional secondary data analysis was performed. Logistic regression was used to identify factors associated with metabolic syndrome in each age group.[Results] The prevalence of metabolic syndrome was 41.7% in the early-old group and 43.7% in the late-old group. In both groups, a body mass index ≥25 kg/m² was significantly associated with metabolic syndrome. Adherence to aerobic physical activity and high sugar intake were inversely associated with metabolic syndrome in the early-old group, and moderate-intensity physical activity was inversely associated, and high household income was positively associated, with metabolic syndrome in the late-old group.[Conclusion] Risk factors for metabolic syndrome differ between early-old and late-old cancer survivors. Tailored health strategies that reflect subgroup characteristics are required to manage risks and improve survivorship care.
