目的了解中国农村育龄妇女维生素A营养状况。方法采用多阶段分层与人口成比例的整群随机抽样方法,选取参加2010—2012年中国居民营养与健康状况调查并有完整个人信息的18~44岁农村育龄妇女作为研究对象,共纳入1279人,分析调查对象维生素A水平及维生素A缺乏率和边缘缺乏率。结果中国农村育龄妇女的血清视黄醇水平为1.63(1.28~2.10)μmol/L,普通农村和贫困农村分别为1.60(1.25~2.05)μmol/L和1.70(1.32~2.17)μmol/L,差异有统计学意义(F=5.66,P=0.018)。中国农村育龄妇女的维生素A边缘缺乏率及缺乏率分别为9.46%和3.05%,普通农村为9.82%和4.13%,贫困农村为9.03%和1.74%,普通农村与贫困农村育龄妇女维生素A缺乏率比较差异有统计学意义(χ~2=6.11,P=0.013),边缘缺乏率比较差异无统计学意义(χ~2=0.23,P=0.632);北方农村育龄妇女维生素A缺乏率、边缘缺乏率分别为1.24%和5.81%,南方农村育龄妇女维生素A缺乏率及边缘缺乏率分别为4.14%和11.67%,南北方育龄妇女维生素A缺乏率及边缘缺乏率比较差异有统计学意义(P<0.05);小学及以下、初中、高中及以上农村育龄妇女维生素A缺乏率分别为1.56%、3.79%和5.03%,差异有统计学意义(χ~2=7.09,P=0.029)。此外,不同年龄、不同家庭收入、不同家庭人口数、不同婚姻状况农村育龄妇女维生素A缺乏率及边缘缺乏率以及不同文化程度农村育龄妇女维生素A边缘缺乏率比较差异均无统计学意义。结论中国农村育龄妇女仍存在不同程度的维生素A缺乏,其中边缘性缺乏更为普遍。
Objective To understand the nutritional status of vitamin A in Chinese women of childbearing age. Methods A stratified population random sampling method was used to select rural women of childbearing age 18-44 who participated in the survey of nutrition and health condition of Chinese residents with complete personal information from 2010 to 2012 as the research object and included 1279 People, analysis of the level of vitamin A and vitamin A deficiency and lack of marginal rate. Results The level of serum retinol was 1.63 (1.28-2.10) μmol / L in rural women of childbearing age in China and 1.60 (1.25-2.05) μmol / L and 1.70 (1.32-2.17) μmol / L in rural areas and poor rural areas, respectively There was a statistically significant (F = 5.66, P = 0.018). The incidence of vitamin A deficiency and deficiency in rural women of childbearing age in China were 9.46% and 3.05%, 9.82% and 4.13% in rural areas and 9.03% and 1.74% in poor rural areas respectively. The vitamin A deficiency rate in rural women and women of reproductive age (Χ ~ 2 = 6.11, P = 0.013). There was no significant difference in marginal rate between the two groups (χ ~ 2 = 0.23, P = 0.632) Rates were 1.24% and 5.81% respectively. The rates of vitamin A deficiency and marginal deficiency in rural women of childbearing age in southern China were 4.14% and 11.67%, respectively. There was significant difference in the rate of vitamin A deficiency and marginal deficiency among women of childbearing age in the north and south (P < 0.05). The vitamin A deficiency rate of women of childbearing age in primary school, junior high school, high school and above were 1.56%, 3.79% and 5.03% respectively, with statistical significance (χ ~ 2 = 7.09, P = 0.029). In addition, there was no significant difference in the incidence of vitamin A deficiency and marginal deprivation among rural women of childbearing age at different ages, different family incomes, different family sizes, and different marital status, as well as the marginal deficiency of vitamin A in rural women of childbearing age at different educational levels. Conclusion There are still some levels of vitamin A deficiency in rural women of childbearing age in China. Among them, the lack of marginalization is more common.
