Prevalence of metabolic syndrome and its association with physical capacity, disability, and self-rated health in Lifestyle Interventions and Independence for Elders Study participants
Abstract
Objectives: To evaluate the prevalence of metabolic syndrome (MetS) and its association with physical capacity, disability, and self-rated health in older adults at high risk of mobility disability, including those with and without diabetes mellitus.
Design: Cross-sectional analysis.
Setting: Lifestyle Interventions and Independence for Elders (LIFE) Study.
Participants: Community-dwelling sedentary adults aged 70 to 89 at high risk of mobility disability (Short Physical Performance Battery (SPPB) score ≤9; mean 7.4 ± 1.6) (N = 1,535).
Measurements: Metabolic syndrome was defined according to the 2009 multiagency harmonized criteria; outcomes were physical capacity (400-m walk time, grip strength, SPPB score), disability (composite 19-item score), and self-rated health (5-point scale ranging from excellent to poor).
Results: The prevalence of MetS was 49.8% in the overall sample (83.2% of those with diabetes mellitus, 38.1% of those without). MetS was associated with stronger grip strength (mean difference (Δ) = 1.2 kg, P = .01) in the overall sample and in participants without diabetes mellitus and with poorer self-rated health (Δ = 0.1 kg, P < .001) in the overall sample only. No significant differences were found in 400-m walk time, SPPB score, or disability score between participants with and without MetS, in the overall sample or diabetes mellitus subgroups.
Conclusion: Metabolic dysfunction is highly prevalent in older adults at risk of mobility disability, yet consistent associations were not observed between MetS and walking speed, lower extremity function, or self-reported disability after adjusting for known and potential confounders. Longitudinal studies are needed to investigate whether MetS accelerates declines in functional status in high-risk older adults and to inform clinical and public health interventions aimed at preventing or delaying disability in this group.
Keywords: Short Physical Performance Battery; grip strength; metabolic syndrome; mobility disability; self-rated health.
