To investigate the effect of vitamin A and Zn supplementation on vitamin A status, haemoglobin level and defecation of children with persistent diarrhea, a total of 160 paediatric patients were randomly assigned to one of four intervention groups: daily supplementation of 1,500 IU VA for 14 days; daily Zn supplementation for 14 days; daily supplementation with both VA and Zn for 14 days; no supplementation. One hundred twenty-seven children with persistent diarrhea finished intervention (33 were lost to follow-up). Among the 127 children, 41 (32.28%) had anaemia, 104 (81.89%) had a VA deficiency and 38 (29.92%) had an iron insufficiency. Supplementation with VA or VA + Zn enhanced the serum VA levels and ameliorated anaemia. Supplementation with Zn and VA + Zn for 5 days significantly improved defecation, where the VA + Zn treatment resulted in superior outcomes. After 14 days of intervention, the total effectiveness rates were 93.94%, 96.77% and 96.67% in the three groups, significantly greater than that of the non-supplementation group (72.73%). These results indicate that single VA or concurrent VA + Zn supplementation can improve vitamin A status, haemoglobin level and defecation. However, concurrent VA + Zn supplementation is the optimal option and can shorten the duration of persistent diarrhea and markedly improve nutritional status.
