  • 简介:目的通过快速评估可避免盲系统评估四川省冕宁县50岁以上人群视力障碍患病率致残原因。方法在2011年6月至8月使用RAAB系统对四川省冕宁县50岁以上居民采用分层、整群随机抽样方法抽取2850人,根据人口比例,分为57个人群组,每个人群组人数为50人,每个人群组采用紧凑段抽样(compactsegmentsampling,CSS),当紧凑段抽样不可行时,采用配额抽样。使用简易视力卡检测视力,用便携式裂隙灯直接检眼镜检查晶状体及眼底情况以明确导致视力残疾原因。结果在冕宁县抽样调查2850人中,2817人接受了检查(98.8%),参照1973年世界卫生组织(WorldHealthOrganization,WHO)视力损伤标准,共有视力残疾者537人,患病率为19.1%,其中盲111人,盲患病率为3.9%(95%可信区间:3.2%-4.7%),严重视力损伤69人,其患病率2.4%(95%可信区间:1.8%-3.1%);视力损伤357人,其患病率12.7%(95%可信区间:10.5%-14.9%),其中可避免盲占87.4%。结论1.冕宁县50岁及以上人群盲患病率为3.9%,严重视力损伤患病率2.4%;视力损伤患病率12.7%,其中可避免盲占87.4%。未经治疗白内障仍然是该县最主要致残原因。2.RAAB系统作为一种在人群中快速筛查可避免调查方法,准确性好,简单实用、高效,重复性强。

  • 简介:目的:探讨中老年人膳食碳水化合物及脂肪摄入与年龄相关白内障(age-relatedcataract,ARC)危险性之间关系。方法:采用以医院为基础病例对照研究方法。病例由45~85岁360例白内障患者组成,对照由同期入住相同医院360例非白内障患者组成,采取1∶1匹配。采用自行设计调查表对研究对象进行调查,内容包括人口学特征、生活方式、以及既往史等,同时还采用一份有效半定量化食物频率调查表(FFQ),获取研究对象膳食营养素摄入情况。应用多因素Logistic回归分析估计碳水化合物及脂肪摄入与ARC关联比值比(OR)及其相应95%可信区间(CI)。结果:调整多种潜在性混杂因素后,碳水化合物摄入增加可使发生ARC危险性升高,与摄入为最低四分位数对照相比较,摄入为最高四分位数病例发生ARCOR为2.161(95%CI:1.107~5.016,P〈0.001)。同样,多不饱和脂肪酸摄入也与ARC呈正相关,摄入为最高四分位数病例发生ARC危险性是最低四分位数对照3倍(OR=2.989,95%CI:1.764~5.062,P〈0.001)。总脂肪摄入与ARC无关(P=0.778)。结论:膳食碳水化合物及多不饱和脂肪酸摄入增加可使发生ARC危险性升高,合理营养、平衡膳食可能有助于预防ARC。
