Therefore , vitamin A supplementation alone may reduce the risk of anemia , by improving hemoglobin and ferritin levels in individuals with low serum retinol levels
ABSTRACT Anemia is a worldwide public health problem that can be related to many causes , including vitamin A deficiency .
The aim of this study was to assess and estimate the effect of vitamin A supplementation ( VAS ) on iron status biomarkers and anemia in humans .
Effects of egg and vitamin A supplementation on hemoglobin, retinol status and physical growth levels of primary and middle school students in Chongqing, China.
Lack of protein and vitamin A influences the growth of student in impoverished mountain areas . The aim of the study was to assess the effects of egg and vitamin A supplementation on hemoglobin , serum retinol and anthropometric indices of 10 - 18 years old students of a low socioeconomic status . A total number of 288 students from four boarding schools were r and omly selected by using cluster sampling method in Chongqing , and they were assigned into supplement group and control group non-r and omly . Students in supplement group received a single 200,000 international units vitamin A and 1 egg/day ( including weekends ) for 6 months . The control group did not receive any supplementation . We measured hemoglobin , serum retinol and height and weight at baseline and after supplementation . The supplementation increased the mean hemoglobin concentration by 7.13 g/L compared with 1.38 g/L in control group ( p<0.001 ) , the mean serum retinol concentration by 0.31 μmol/L compared with 0.09 μmol/L in the control group ( p=0.005 ) , the mean height-for-age z score by 0.05 compared with 0.03 in the control group ( p=0.319 ) , the mean weight-for-age z score by 0.05 compared with -0.12 in the control group ( p<0.001 ) . Our results revealed that egg and vitamin A supplementation is an effective , convenient , and practical method to improve the levels of hemoglobin , serum retinol and prevent the deterioration of growth in terms of weight for primary and middle school students from outlying poverty-stricken areas . Our intervention did not have a beneficial effect on linear growth
Therefore , vitamin A supplementation alone may reduce the risk of anemia , by improving hemoglobin and ferritin levels in individuals with low serum retinol levels
