A biochemical assessment of the vitamin and trace element status of 756 institutionalized elderly men and women, 66-103 years old (average 83.5 +/- 7.6 y), was conducted in 26 nursing homes in different areas of France. Serum concentrations of beta- and alpha-carotene, beta-cryptoxanthin, lycopene, retinol, alpha- and gamma-tocopherol, vitamin C, zinc and selenium were measured. A difference in biochemical markers according to sex was observed for vitamins E and C: elderly women had higher levels of alpha-tocopherol and vitamin C than elderly men. When expressed as a ratio of cholesterol, the difference between sexes for alpha-tocopherol disappeared. Simple regression analysis showed that most vitamins and trace elements were significantly negatively correlated with age. A high prevalence of low concentrations of vitamin C, zinc and selenium was revealed.
在法国不同地区的26家养老院中，对756名年龄在66至103岁（平均83.5±7.6岁）的机构养老男女进行了维生素和微量元素状况的生化评估。测量了血清中β-胡萝卜素、α-胡萝卜素、β-隐黄质、番茄红素、视黄醇、α-生育酚、γ-生育酚、维生素C、锌和硒的浓度。观察到维生素E和C的生化指标存在性别差异：老年女性的α-生育酚和维生素C水平高于老年男性。当以胆固醇的比例表示时，α-生育酚的性别差异消失。简单回归分析表明，大多数维生素和微量元素与年龄呈显著负相关。结果显示维生素C、锌和硒低浓度的患病率很高。
