ABSTRACT
Objective:
To explore the association between hair trace element and all-cause death in the elderly in Hainan Province.Methods:
The subjects of the study were elderly people from China Hainan Centenarian Cohort Study, a total of 163 elderly were included. The association between hair trace element level and all-cause death was analyzed by using Cox proportional risk regression model.Results:
After fully adjusting the covariates, the multiple Cox proportional hazards regression analyses showed that selenium (Se), manganese (Mn), strontium (Sr) concentrations in hair were significantly associated with all-cause mortality, the hazard ratio (HR) were 0.72 (95%CI 0.54-0.98, P=0.035), 1.50 (95%CI 1.07-2.11, P=0.020) and 0.54 (95%CI 0.37-0.79, P=0.001), respectively. Subgroup and cross analysis showed that hair copper (Cu) were significant association with death in the people with anemia, the HR were 1.81 (95%CI 1.13-2.88, P=0.013). And, hair Mn interacted with anemia, the HR was 0.46 (95%CI 0.22-0.94, P=0.033).Conclusions:
Se, Mn and Sr concentrations in hair were associated with the elevated risk for all-cause death in the elderly in Hainan. Se, Mn and Sr concentrations in hair can be used as a reference index for the prediction of the death risk of long-lived elderly in community, suggesting that the daily diet of elderly people are rich and diverse, in order to maintain normal and balanced trace element content in the body.
