To evaluate nutritional status of vitamin A( VA) among Chinese rural fertile women in 2010-2012.
A multi-stage stratified sampling and population proportional stratified random sampling method was used and the participants of rural fertile women who were 18-44 years old and had completed personal information data during the 2010-2012 National Nutrition and Health Survey were included( n = 1279). The level of serum retinol, rate of VA marginal deficiency anddeficiency among the fertile women were analyzed.
In 2010-2012, the P50( P25-P75) level of serum retinol was 1. 63( 1. 28-2. 10) μmol/L for Chinese rural fertile women, 1. 60( 1. 25-2. 05) μmol/L for fertile women from ordinary rural area and1. 70( 1. 32-2. 17) μmol/L for fertile women from poverty rural area. The level of serum retinol of fertile women from poverty rural area was statistically higher than that of ordinary rural area( P = 0. 007). The rate of VA marginal deficiency and deficiency among the Chinese rural fertile women was 9. 46% and 3. 05%, respectively. The rate of VA marginal deficiency and deficiency among the fertile women from ordinary rural area and poverty rural area was 9. 82%, 4. 13%, 9. 03% and 1. 74%, respectively. The rate of VA deficiency among the fertile women from ordinary rural was statistically higher than that of poverty rural( P = 0. 013), but no statistically differences in the rate of VA marginal deficiency were found( P > 0. 05). Moreover, the statistically differences of rate of VA marginal deficiency and deficiency were also observed in the different regions and educational level( only VA deficiency). There were no statistically differences of VA marginal deficiency and deficiency were found in the other variables.
The different extent of VA deficiency still present and more popular for the VA marginal deficiency among Chinese fertile women.
评估2010 - 2012年中国农村育龄妇女维生素A（VA）的营养状况。
采用多阶段分层抽样和人口比例分层随机抽样方法，纳入2010 - 2012年全国营养与健康调查中年龄在18 - 44岁且完成个人信息数据的农村育龄妇女参与者（n = 1279）。分析育龄妇女血清视黄醇水平、VA边缘缺乏率和缺乏率。
2010 - 2012年，中国农村育龄妇女血清视黄醇的P50（P25 - P75）水平为1.63（1.28 - 2.10）μmol/L，普通农村地区育龄妇女为1.60（1.25 - 2.05）μmol/L，贫困农村地区育龄妇女为1.70（1.32 - 2.17）μmol/L。贫困农村地区育龄妇女血清视黄醇水平在统计学上高于普通农村地区（P = 0.007）。中国农村育龄妇女VA边缘缺乏率和缺乏率分别为9.46%和3.05%。普通农村地区和贫困农村地区育龄妇女VA边缘缺乏率和缺乏率分别为9.82%、4.13%、9.03%和1.74%。普通农村地区育龄妇女VA缺乏率在统计学上高于贫困农村地区（P = 0.013），但VA边缘缺乏率无统计学差异（P > 0.05）。此外，在不同地区和教育水平（仅VA缺乏）中也观察到VA边缘缺乏率和缺乏率的统计学差异。在其他变量中，VA边缘缺乏和缺乏无统计学差异。
中国育龄妇女存在不同程度的VA缺乏，且VA边缘缺乏更为普遍。
