Information on morbidity and socioeconomic also were recorded. The evaluate the degree of improvement, score on nutritional status, BSR and XCR were made. The result showed that after 6 month there were improvement in anthropometry status, morbidity rate, Hb, Ht, BSR, Ig G and CXR for both groups. The treatment group was improved in 72 percent subjects meanwhile the control group was improved in 58 percent subjects. Analysis for scoring improvement showed that the treatment group had better improvement 2.4 times than the control group.
