【摘要】：目的分析2010—2012年中國農村地區(qū)6~17歲兒童青少年維生素A營養(yǎng)狀況。方法基于2010—2012年中國居民營養(yǎng)與健康監(jiān)測項目,采用多階段分層與人口成比例的隨機抽樣方法,以一般農村和貧困農村地區(qū)調查點送檢的兒童青少年血清樣本為研究對象,采用單純隨機抽樣法共抽取樣品5888份,高效液相色譜法(HPLC法)測定血清視黃醇濃度,評價農村兒童青少年的維生素A營養(yǎng)狀況。結果中國農村兒童青少年血清視黃醇濃度為(1.44±0.58)μmol/L,其中一般農村和貧困農村分別為(1.40±0.56)μmol/L和(1.46±0.60)μmol/L(t=1.88,P0.05)。6~11歲組一般農村和貧困農村血清視黃醇濃度分別為(1.31±0.53)μmol/L和(1.37±0.60)μmol/L,均顯著低于12~17歲組的(1.52±0.57)μmol/L和(1.52±0.60)μmol/L(t=11.90和t=5.54,P0.05)。農村兒童青少年維生素A總缺乏率為5.53%,其中一般農村和貧困農村分別為6.14%和4.55%;邊緣缺乏率為18.75%,其中一般農村和貧困農村分別為19.17%和18.07%,差異均無統計學意義。結論中國農村地區(qū)兒童青少年的維生素A缺乏仍普遍存在,其中邊緣缺乏情況較為突出。
[Abstract]:Objective to analyze the vitamin A nutritional status of children and adolescents aged 6 to 17 years in rural China from 2010 to 2012. Methods based on the nutrition and health monitoring project of Chinese residents from 2010 to 2012, a multi-stage stratified and population-proportional random sampling method was used. The serum samples of children and adolescents in general rural areas and poor rural areas were studied. A total of 5888 samples were collected by random sampling method. The serum retinol concentration was determined by HPLC. Results the serum retinol concentrations of Chinese rural children and adolescents were 1.44 鹵0.58 渭 mol / L, 1.40 鹵0.56 渭 mol/L and 1.46 鹵0.60 渭 mol / L respectively in rural and poor rural areas, respectively. Results the serum retinol concentrations of Chinese rural children and adolescents were 1.48 鹵0.58 渭 mol / L and 1.46 鹵0.60 渭 mol / L respectively. 611 years old in rural and poor rural areas, respectively, were 1.40 鹵0.56 渭 mol/L and 1.46 鹵0.60 渭 mol / L respectively. The concentrations of yellow alcohol were 1.31 鹵0.53 渭 mol/L and 1.37 鹵0.60 渭 mol / L, respectively, which were significantly lower than those of 120-17 years old group (1.52 鹵0.57) 渭 mol/L and 1.52 鹵0.60 渭 mol/L(t=11.90 and Tet 5.54 渭 mol/L(t=11.90, respectively. The total vitamin A deficiency rate of rural children and adolescents was 5.53, of which 6.14% and 4.55 were in rural and poor rural areas, respectively, and the marginal deficiency rate was 18.75b. The difference was not statistically significant between villages and poor rural areas. Conclusion Vitamin A deficiency in children and adolescents in rural areas of China is still widespread. The lack of edge is more prominent.
