Associations between sarcopenic obesity and the risk of cardiovascular-kidney-metabolic syndrome progression: insights from the China health and retirement longitudinal study
摘要
This study aimed to explore the association between sarcopenic obesity (SO) and advanced stages of cardiovascular-kidney-metabolic (CKM) syndrome, as well as to prospectively examine its relationship with cardiovascular events in CKM stages 0–3.
MethodsData were drawn from the China Health and Retirement Longitudinal Study (2011–2020) encompassing a median follow-up of 9.0 years for incident cardiovascular events. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 criteria. Non-sarcopenic participants with optimal body mass index or waist circumference served as the reference group. Outcome was major adverse cardiovascular events (MACEs) defined as a composite of all-cause death, cardiovascular problem, and stroke. Multivariable logistic regression and Cox proportional hazards models were employed to assess associations.
ResultsA total of 6,766 participants (age 60.0 ± 9.9 years, 46.9% male) were included. At baseline, SO was associated with a significantly higher likelihood of advanced CKM stages [OR (95% CI): 3.317 (2.533, 4.345)] compared to reference. Similarly, sarcopenic overweight [OR (95% CI): 3.171 (2.601, 3.865)] and sarcopenic abdominal obesity [OR (95% CI): 3.268 (2.662, 4.013)] were also linked to higher odds of advanced CKM stages. Over a median follow-up of 9.0 years, 1,322 participants (21.1%) from CKM stages 0–3 experienced MACEs. After adjusting for multiple covariates, SO was associated with an increased risk of MACEs [HR (95% CI): 2.248 (1.789, 2.824)] compared to reference. Similarly, sarcopenic overweight [HR (95% CI): 1.768 (1.465, 2.135)] and sarcopenic abdominal obesity [HR (95% CI): 1.730 (1.414, 2.115)] were also associated with an elevated risk of MACEs.
ConclusionsSO was significantly associated with more advanced stages of the CKM spectrum. Furthermore, among individuals categorized with CKM stages 0–3 and without pre-existing cardiovascular disease, SO was independently associated with a substantially elevated risk of future MACEs.
