Abstract:

Objective To understand the levels of Mn,Fe,Zn,Ca,and Mg elements in the hair of the adults, and to discuss their correlations with the body mass index(BMI).Methods A total of 657 adults,which were sampled through random cluster sampling method,were enrolled by questionnaire survey,physical examination,and hair sample collection. The levels of Mn,Fe,Zn,Ca,and Mg elements in the hair were detected by ICP-MS method.Results There were siginficant differences of the levels of Mn,Fe,Zn,Ca,and Mg elements in hair of the adults with different genders and ages(P<0.05).322(49.0%)adults exceeded the BMI standard in 657 adults. There were no significant differences of the BMI and BMI exceeded rates between the adults with different genders(P>0.05).There were significant differences of the BMI and BMI exceeded rates between the adults with different ages (P<0.05).The BMI exceeded rate was high in the adults aged 40-69 years,and it reached the highest in the adults aged 50-59 years. The levels of five kinds of mineral elements in the BMI exceeded adults were lower than those with normal BMI(P<0.05).After age and gender were controlled,the partial correlation analysis results showed BMI had negative correlation with Mn(rs=-0.117,P=0.003),Fe(rs=-0.114,P=0.004),Ca(rs=-0.108,P=0.006) and Mg(rs=-0.089,P=0.023) elements; and had no correlations with Zn element (rs=0.045,P=0.247).Conclusion Age and gender are the potential influencing factors for the levels of mineral elements in human.The levels of Mn,Fe,Zn,Ca,and Mg elements of the BMI exceeded adults are decreased significantly. The BMI exceeded adults should pay attention to the intake of mineral elements reasonably.
