摘要

充足的α -生育酚对育龄女性很重要。我们研究了莫桑比克中部14 - 19岁女孩的饮食摄入和α -生育酚以及α和γ -生育酚状态指标的来源。我们还探讨了与α -和γ -生育酚状态相关的因素。参与者(508人)来自2010年进行的横断面ZANE研究。我们招募了两个独立的样本,一个在1月至2月,另一个在5月至6月。我们采集静脉血样本并进行24小时饮食回忆访谈。在抽血时,11%的参与者怀孕了,10%的参与者正在哺乳。在两个季节的总样本中,α -生育酚的中位数摄入量为6⋅7 mg/d,血浆α -和γ -生育酚的平均浓度分别为13⋅5和0⋅75 μmol/l,维生素E不足(α -生育酚<12 μmol/l)的发生率为36⋅7% (95% CI: 31⋅9-42⋅0%)。无论使用何种三个指标(血浆浓度、α -生育酚:总胆固醇比率、γ -生育酚:α -生育酚比率),季节和哺乳期状态都是α -生育酚状态的重要预测因子。哺乳期母亲与α -生育酚水平呈负相关,而在1 - 2月采集血液样本(芒果和深绿色绿叶蔬菜是α -生育酚的主要来源)与α -生育酚水平呈正相关。综上所述,维生素E不足在莫桑比克中部地区很常见,而且由于饮食的季节性变化,情况可能有所波动。我们认为,在资源贫乏的环境中,哺乳期母亲尤其有α -生育酚状态差的风险。

Prevalence of vitamin E inadequacy, dietary intake and sources of alpha-tocopherol, and predictors of alpha- and gamma-tocopherol status in adolescent girls in Central Mozambique
Abstract An adequate alpha-tocopherol status is important for females at reproductive age. We studied the dietary intake and sources of alpha-tocopherol and alpha- and gamma-tocopherol status indicators in 14–19-year-old girls in Central Mozambique. We also explored factors associated with alpha- and gamma-tocopherol status. The participants (n 508) were from the cross-sectional ZANE Study that was conducted in 2010. We recruited two separate samples, one in January–February and the other in May–June. We collected venous blood samples and conducted 24 h dietary recall interviews. At the time of blood sampling, 11 % of participants were pregnant and 10 % were lactating. In the total sample, both seasons combined, the median intake of alpha-tocopherol was 6⋅7 mg/d, the mean plasma alpha- and gamma-tocopherol concentrations were 13⋅5 and 0⋅75 μmol/l, respectively, and the prevalence of vitamin E inadequacy (alpha-tocopherol <12 μmol/l) was 36⋅7 % (95 % CI: 31⋅9–42⋅0 %). Season and lactation status were significant predictors of alpha-tocopherol status regardless of which the three indicators (plasma concentration, alpha-tocopherol:total cholesterol ratio, gamma-tocopherol:alpha-tocopherol ratio) were used. Being a lactating mother was negatively associated and having a blood sample taken in January–February, when the main sources of alpha-tocopherol were mango and dark green leafy vegetables, was positively associated with alpha-tocopherol status. In conclusion, vitamin E inadequacy was common in Central Mozambique, and the status may fluctuate due to seasonal changes in the diet. We suggest that lactating mothers are specifically at risk of poor alpha-tocopherol status in resource-poor settings.
