METHODS In 5 poor counties of Gansu Province, children aged 4 - 12 months were enrolled and divided into two groups. In addition to the usual home-made complementary food, all the children were fed one package of either formula I or formula UI per day, protein and micronutrient were supplemented in formula I group. Formula II provided the same energy as formula I . Both groups were supplemented with vitamin A, weight and height measurements have been done every 3 months, and hemoglobin tests were done every 6 month. Development quotient was measured when they were aged 24 month.
  
  
  RESULTS
  Development quotient of 475 children were tested. The difference of Development quotient between the two groups is statistically significant ( P < 0.05), gross motor development also is different (P < 0.05), there are no difference in time of supplements, nutrition status, sex ratio, mother' s education between two group, but hemoglobin and anemia prevalence of children in formula I group is significant lower than Formula II group.
