  OBJECTIVE
  investigation of vitamin D sufficiency in children with recurrent bronchitis (RB), living in Zaporozhye, by examining of 25(OH)D and parathormone serum level. The study involved 120 children aged 4 to 10 years, divided into 2 groups (60 children each): 1) children, occasionally ill with acute respiratory infections, 2) children with RB. Investigation of serum 25(OH)D was conducted between November and February. Decrease of vitamin D3 below 30 ng/ml in serum was observed in 85% (р<0,05) patients with RB (insufficiency), below 20 ng/ml - in 15% (deficit). The children aged 4-10 years with RB, who living in Zaporozhye, have decrease of serum 25(OH)D that characterizes their vitamin D3 supply as insufficient.
