Abstract

OBJECTIVE

To analysis the vitamin A nutritional status of 6-to 17-year-old children and adolescents between 2010-2012 in rural China.

METHODS

Based on the China Health and Nutrition Survey 2010-2012 project, the serum vitamin A samples of children and adolescents from survey sites of rural area were selected by random sampling method, and 5888 cases of samples were detected using the high performance liquid chromatography method to evaluate their vitamin A nutritional status.

RESULTS

The serum retinol concentration of children and adolescents in rural area was( 1. 44 ± 0. 58) μmol/L, and were( 1. 40 ± 0. 56) μmol/L in general rural areas and( 1. 46 ± 0. 60) μmol/L in poverty rural areas respectively( t = 1. 88, P < 0. 05). The serum retinol concentration of6-to 11-year-old were( 1. 31 ± 0. 53) μmol/L and( 1. 37 ± 0. 60) μmol/L, and serumretinol concentration of 12-to 17-year-old were( 1. 52 ± 0. 57) μmol/L and( 1. 52 ±0. 60) μmol/L( t = 11. 90 and t = 5. 54, P < 0. 05). The prevalence of vitamin A deficiency was 5. 53%, and were 6. 14% in general rural areas and 4. 55% in poverty rural areas, respectively( P > 0. 05). The prevalence of marginal vitamin A deficiency were 18. 75%, and were 19. 17% in general rural areas and 18. 07% in poverty rural areas, respectively( P > 0. 05).

CONCLUSION

The situation of vitamin A deficiency in rural China are still widespread, the high prevalence of marginal vitamin A deficiency is more prominent.

摘要

目的

分析2010 - 2012年中国农村6至17岁儿童及青少年的维生素A营养状况。

方法

基于2010 - 2012年中国健康与营养调查项目，采用随机抽样方法选取农村调查点儿童及青少年的血清维生素A样本，共5888例样本采用高效液相色谱法检测，以评估其维生素A营养状况。

结果

农村儿童及青少年血清视黄醇浓度为（1.44±0.58）μmol/L，一般农村地区为（1.40±0.56）μmol/L，贫困农村地区为（1.46±0.60）μmol/L（t = 1.88，P < 0.05）。6至11岁儿童血清视黄醇浓度为（1.31±0.53）μmol/L，12至17岁儿童血清视黄醇浓度为（1.52±0.57）μmol/L；一般农村地区6至11岁儿童血清视黄醇浓度为（1.37±0.60）μmol/L，12至17岁儿童血清视黄醇浓度为（1.52±0.60）μmol/L（t = 11.90及t = 5.54，P < 0.05）。维生素A缺乏患病率为5.53%，一般农村地区为6.14%，贫困农村地区为4.55%（P > 0.05）。边缘性维生素A缺乏患病率为18.75%，一般农村地区为19.17%，贫困农村地区为18.07%（P > 0.05）。
