[目的 ]观察膳食抗氧化剂对老年性白内障的影响。[方法 ]选择潍坊市 30名 60～ 75岁健康志愿者 (A组 )与 30名老年性白内障患者 (B组 )。对 B组人群进行 1 5个月的膳食营养指导 ,于营养干预前后 ,通过 7日询问法调查两组人群膳食中抗氧化剂的摄入量 ,检测血清谷胱甘肽过氧化物酶及视力等。 [结果 ]营养干预前 B组膳食抗氧化剂每日摄入量、血液抗氧化酶活力明显低于 A组 P <0 .0 1 )。营养干预后 B组视黄醇当量、维生素 E、维生素 C、硒的每日摄入量明显增加 ,血清中超氧化物歧化酶与谷胱甘肽过氧化物酶活性、血清硒含量明显升高 ,血清脂质过氧化产物丙二醛含量显著降低 P <0 .0 1 ) ;视力下降得到控制。[结论 ]膳食抗氧化剂的摄入量不足可能与老年性白内障有一定关系 。
