Abstract:
Objective:To assess the levels and abnormal rates of trace elements and vitamins among older patients in Beijing Hospital, and to analyze the correlations between these measured indicators.Methods:This study selected 49 older individuals who underwent physical examinations at Beijing Hospital between May 2021 and March 2024.The participants were divided into two age groups: 60-79 years old(23 cases)and 80-100 years old(26 cases). Levels' differences of trace elements and vitamins between the two age groups were analyzed.Pearson correlation analysis was used to investigate the correlations among the tested indicators, and multivariate analysis was conducted using a generalized linear regression model.Results:Among the 49 older individuals, the overall abnormal rate for trace element test results was 8.16%(4 cases), with 2 cases of iron(Fe)deficiency(4.08%)and 2 cases of calcium(Ca)deficiency(4.08%). The overall abnormal rate for vitamin test results was 24.49%(12 cases), which included 5 cases of vitamin B2 deficiency(10.20%), 1 case of vitamin C deficiency(2.04%), and 6 cases of vitamin D deficiency(12.24%). Statistically significant differences were observed between the two age groups in zinc(Zn)and vitamin C levels( t=2.84, 2.83; P=0.007, 0.007). Pearson correlation analysis revealed correlations among 19 pairs of indicators.The top five correlations were between plumbum(Pb)and cadmium(Cd)( r=0.769, P<0.001), Fe and manganese(Mn)( r=0.685, P<0.001), Ca and magnesium(Mg)( r=0.677, P<0.001), vitamin B12 and vitamin C( r=0.455, P=0.001), and vitamin B9 and vitamin D( r=0.422, P=0.003), respectively.The results of the multivariate analysis indicated that, after adjusting for the effects of age group and gender, statistical differences in correlations remained among the remaining trace elements and vitamins, except for those between vitamin B1 and vitamin B12, vitamin B1 and vitamin C, and vitamin A and vitamin D (all P<0.05). Conclusions:The deficiency rates of trace elements and vitamins remain notably high among older patients in our hospital, underscoring the necessity for enhanced nutritional supplementation and regular monitoring of trace element and vitamin levels within this population.Furthermore, a correlation exists between trace elements and vitamins, which offers valuable insights for the diagnosis and treatment of related diseases.
