To report the prevalence and the associated factors leading to cataract among the Iranian population living in Gilan Province, Iran.
This population-based cross-sectional study was performed from June to November 2014 on 2,975 residents aged ≥ 50 years old living in urban and rural regions of the Gilan Province in Iran. A representative sample of residents in the province was recruited into the study through door-to-door visiting, and baseline data were collected by questionnaire. All participants were referred to the medical center for comprehensive ophthalmic examination, laboratory tests, and blood pressure measurement.
Among the population, 2,588 (86.99%) subjects were eligible to be included in this study, categorized either into the cataract or the non-cataract group. The mean age of participants was 62.59 ± 8.92 years, and 57.5% were female. Higher prevalence of cataract was found in individuals of older ages (odds ratio (OR) = 1.13; 95% confidence interval (CI) = 1.10 to 1.16; P < 0.001) and a history of previous ocular surgery (OR = 5.78; 95% CI = 2.28 to 14.63; P < 0.001). At the same time, a lower prevalence of cataract was seen in patients exposed to sunlight for more than 4 h per day (OR = 0.49; 95% CI = 0.32 to 0.73; P = 0.001).
Cataract affects 50.50% of the study population, especially those over 80. The mildest form of cataract, grade zero, is the most common. Surgery for cataract has good outcomes. The risk of cataract is higher for those older or who have had eye surgeries. People not affected by cataract tend to be exposed to more sunlight.
报告居住在伊朗吉兰省的伊朗人群中白内障的患病率及相关因素。
2014年6月至11月，对居住在伊朗吉兰省城乡地区的2975名年龄≥50岁的居民进行了这项基于人群的横断面研究。通过挨家挨户走访招募该省居民的代表性样本，并通过问卷调查收集基线数据。所有参与者均被转至医疗中心进行全面眼科检查、实验室检查和血压测量。
在该人群中，2588名（86.99%）受试者符合纳入本研究的条件，分为白内障组或非白内障组。参与者的平均年龄为62.59±8.92岁，女性占57.5%。年龄较大者（优势比（OR）=1.13；95%置信区间（CI）=1.10至1.16；P<0.001）和既往有眼部手术史者（OR=5.78；95%CI=2.28至14.63；P<0.001）白内障患病率较高。同时，每天暴露在阳光下超过4小时的患者白内障患病率较低（OR=0.49；95%CI=0.32至0.73；P=0.001）。
白内障影响了50.50%的研究人群，尤其是80岁以上者。最轻微的白内障形式，即零级，最为常见。白内障手术效果良好。年龄较大或有眼部手术史者患白内障的风险较高。未患白内障的人往往暴露在更多阳光下。
