Study on the relationship between hemoglobin concentration and metabolic syndrome in the elderly
Objective To explore the relationship between hemoglobin concentration and metabolic syndrome(MetS)and its components in elderly individuals,and to provide a scientific basis for the prevention and treatment of MetS in the elderly.Methods A total of 35 966 elderly people aged ≥65 who underwent health examinations at a community health service center in a certain district of Qingdao from January 1 to December 31,2021 were selected as the research subjects.Ac-cording to the third percentile of hemoglobin concentration,they were divided into three groups:T1(＜132 g/L),T2(132-144 g/L),and T3(≥144 g/L).Logistic regression analysis was used to investigate the impact of hemoglobin on MetS and its components.Results There were 18 202 MetS patients,with a prevalence rate of 50.60％.The waist circ-umference(t=71.23,P＜0.001),systolic blood pressure(t=50.66,P＜0.001),diastolic blood pressure(t=29.51,P＜0.001),triglycerides(t=68.01,P＜0.001),fasting blood glucose(t=63.17,P＜0.001),and hemoglobin(t=24.12,P＜0.001)levels in the MetS group were higher than those in the non MetS group,but the high-density lipopro-tein cholesterol content in the MetS group was lower than that in the non MetS group(t=27.19,P＜0.001),and the differences were statistically significant.The results of logistic regression analysis showed that after controlling for confounding factors,the risk of MetS(95％CI:1.80-2.01),abdominal obesity(95％CI:1.52-1.73),hypertension(95％CI:1.31-1.51),hyperglycemia(95％CI:1.47-1.64),and dyslipidemia(95％CI:1.28-1.44)in the hemoglo-bin T2 group was 1.91,1.62,1.41,1.44,and 1.36 times higher than that in the T1 group,respectively,with all P＜0.001.The risk of MetS(95％CI:2.09-2.34),abdominal obesity(95％CI:1.84-2.12),hypertension(95％CI:1.53-1.77),hyperglycemia(95％CI:1.56-1.74),and dyslipidemia(95％CI:1.33-1.49)in the T3 group was 2.21,1.98,1.65,1.64,and 1.41 times higher than that in the T1 group,respectively,with all P＜0.001.Conclusion Hemo-globin is associated with MetS and its components,and hemoglobin levels can serve as a clinical predictive indicator for MetS and its components in the elderly.
