摘要:
方法: 参与者填写的基线频率问题纳尔人。基线和年度镜头照片是集中分级的。 Multivariate models controlling for previously identified risk factors for cataracts tested for the association of cataracts with reported dietary intake, using the lowest quintile as reference.
MAIN OUTCOME MEASURES: Cataract surgery, cataract status (type and severity) at baseline, and development of白内障。
结果: 在基线时,饮食中核黄素和B12增加与核和皮质晶状体不相关。在比较有或没有白内障的人的比较中,核黄素摄入量最高的人与那些最低的摄入量具有以下关联:轻度核白内障:优势比(OR),0.78; 95%置信区间(CI),0.63-0.97;中度核白内障:或0.62; 95%CI,0.43-0.90;和轻度皮质性白内障:或0.80; 95%CI,0.65-0.99。对于B12,结果是:轻度核白内障:或0.78; 95%CI,0.63-0.96;中度核白内障:或0.62; 95%CI,0.43-0.88;和轻度皮质性白内障:或0.77; 95%CI,0.63-0.95。与最低的五分之一(OR,0.67; 95%CI,0.45-0.99)相比,最高的饮食B6摄入量与中度核透镜不透明度的风险降低有关。烟酸和B12的最高饮食摄入水平与未服用中心(辉瑞,纽约,纽约)多种维生素的参与者中轻度核或轻度皮质性白内障的风险降低有关。对于在研究期间服用多种维生素的参与者,饮食叶酸的最高摄入量与轻度后囊膜的风险增加有关不透明的发展。 No statistically significant associations were found between lutein plus zeaxanthin intake and presence at baseline or development of nuclear or cortical lens opacity outcomes.
CONCLUSIONS: These findings are consistent with earlier studies suggesting that dietary intake of B vitamins may affect the occurrence of age-related lens不熟悉。保证进一步调查。
