An investigation of the metal concentrations of calcium, copper, iron, magnesium, and zinc in three groups of young female hair (n = 180), from women aged between 15 to 19 years, with different body mass indexes (BMI) of BMI < 18, BMI between 18 and 23, and BMI > 24 was performed using atomic absorption spectroscopy (AAS). The hair samples were washed with organic solvent (normal hexane : ethyl alcohol : acetone, v/v, 4 : 2 : 1) to remove the external contents and then digested with a microwave digester. The hair samples were analyzed using a flame atomic absorption spectrophotometer. The BMI < 18 group (n = 45) had the highest concentrations of calcium, copper, iron, magnesium and zinc while the BMI between 18 and 23 group (n = 75) had the second highest concentrations. The BMI > 24 group (n = 60) had the lowest concentrations. Further -more, when we compared the concentrations of calcium, copper, iron, magnesium, and zinc between the groups with BMI < 18 and BMI > 24, there are significant differences (p < 0.05) in the calcium, copper, magnesium, and zinc concentrations between these two groups. The difference was especially significant (p < 0.01) in iron concentration.
