Objective To evaluate the intervention effects of Identification and Management of Feeding Difficulties (IMFeD) tools for eating behavior problem in children, and to provide scientific basis for standardized intervention measures. Methods Prospective randomized controlled clinical study method was used for 211 children with the eating behavior problems in 8 communities and 4 kindergartens in Shenyang.The intervention group was used by IMFeD tools, the control group was used by the common health care technology. Results After 5 follow-up within 9 months, The comprehensive decreased scoreΔ (M9-M0) of the eating behavior problems in the intervention group was higher than that in control group, the difference was statistically significant(P＜0.01).In different age group, that of 3 and 4 years old group had statistically significant difference(P＜0.01);Comparison before and after the intervention group was decreased significantly(t=21.2, P＜0.01), and the decreased score increased gradually with the increase of age;Through the comparison of the intervention group and the control group, the protective rate of IMFeD tool was 66.8%, the index of effectiveness was 3.0;The protective rate was 85.2% through the comparison of M9 and M0 in the intervention group, the effect index was 6.7; NNT was 1.3 (95%CI:1.2~1.5). Conclusion Effects of applying IMFeD tool is obvious for diagnosing, classifying and intervening the eating behavior problems of children.
