*Mean, standard error, and median were calculated for the values of vitamin A. Significant difference by socio-demographic factors was determined using nonparametric median test
^§If the difference was significant among more than two groups, multiple-comparison was further conducted by Student-Newman-Keuls (SNK). The same characters (a,b,c,d) indicated non-significant difference between the two sub-groups, while the different characters indicated significant difference, p < 0.05
