And there was no significant difference in anxiety between acutely ill children and healthy children. There was significant difference in anxiety between groups of ill and healthy children(P<0.01) .The anxiety of ill children was higher than that of healthy children. 2) There was no significant correlation between children's anxiety and their age. 3) There was no significant difference in children's anxiety related to frequency of hospital admission. 4) There was significant correlation between children's anxiety and duration of illness(P<0.01). The longer the duration of illness is, the higher children's anxiety is. 5) There was significant difference in mothers' anxiety between groups of fatally ill and chronically ill children(P<0.05).
