Systematic Review: Dietary Intervention only Decreases the Risk of Iron Deficiency Anemia among Children

ron Deficiency Anemia is the most common type of anemia related to malnutrition worldwide. It represents a major problem in developing countries. Purpose: To determine the effect of dietary intervention only on the occurrence of IDA. Methods: In 6 articles with 8 eligible outcomes, a total of 676 individuals were included within the present systematic review with no of cases 339 and 337 control. Dietary intervention is mainly to eat about 3040 g of liver, sheep liver, chicken liver, or 12 eggs, or 30 red dates, etc. before or after the meal once a day. Result: clinical recovery—clinical symptoms disappeared completely, and hemoglobin returned to normal. Clinically effective—clinical symptoms relieved, and the rise of HB >15 g/dl. Invalid— clinical symptoms did not improve or obviously improve, and the rise of HB to 15 g/dl. Dietary intervention was associated with an average change in clinical effectiveness from 94.0% to 100.0%. The clinical effect was increased in dietary intervention in all six trials, among which three trials had a statistical increase of clinical effect. Tests for heterogeneity showed no significant differences across studies, thus the fixed effect model was employed. The overall pooled estimate of or in the dietary intervention on children with IDA was 5.03 (95%) CI: 3.098.18, Z = 6.50, P<0.001. Conclusion: Dietary intervention on children with IDA was established that had a beneficial effect.
