Prevalence and Risk Factors for Adult Cataract in the Jingan District of Shanghai

Abstract

Purpose. We report the prevalence of age-related cataract (ARC) in the Jingan district of Shanghai and analyze the risk factors for ARC to be better prepared for the increasing burden of cataracts as a significant cause of visual impairment worldwide. Methods. From March to June 2010, a population-based, cross-sectional study was conducted in a community selected by stratified cluster sampling in the Jingan district of Shanghai. Residents aged 40 and older were recruited and investigated by questionnaires and ophthalmic examination. Univariate and multivariate logistic regression models were used to evaluate the association of these risk factors with any cataract. Results. A total of 2894 subjects aged 40 years and above were included in our study. Nine hundred forty-eight people (32.8%) were diagnosed with cataract, including 845 with bilateral cataracts (29.2%) and 292 with moderate and severe visual impairment (low vision, 10.1%). There were significant differences in low vision among different age groups and gender (Χ2age = 84.420, P age < 0.001, Χ2gender = 7.696, P gender = 0.021). For any cataract, we found age (OR = 1.107, 95% CI: 1.094–1.120) and refractive error (OR = 1.352, 95% CI: 1.127–1.622) were independent risk factors. Conclusion. The prevalence of cataract is estimated to be nearly one-third of the sample, increasing with age. We provided further evidence that age and refractive error are independent cataract risk factors.

Characteristics of cataract patients who underwent cataract surgery in H. L. Manambai Abdulkadir hospital Sumbawa

“…Estrogen also functions as a protective hormone against oxidative stress which is related to lens opacification. 2,3 In this study, there were more men underwent cataract surgery with a ratio of 54.26% and 45.7% to women. This is consistent with a study conducted by Fang et al although 60% of cataract patients are women, men are 1.39 times more likely to undergo cataract surgery than women.…”

“…Worldwide cataract prevalence is dominated by women. 3 Older age and lower socioeconomic status are associated with greater differences in cataract incidence by sex. 9 There is also a decrease in estrogen hormone in women during menopause which increases the risk of cataracts.…”

“…2 Age is a factor the main risk of developing cataracts in men and women. Accumulation of oxidative stress in the lens, refractive disorders, smoking, exposure to UV rays, chronic diseases such as hypertension and diabetes are also said to be risk factors for cataracts 3 . Based on data from the WHO, out of 1 billion people, as many as 94 million cases of distance vision problems or blindness are caused by cataracts.…”

Treatment of Basal Cell Carcinoma of the Lower Eyelid With High-Dose-Rate Brachytherapy

“…Our experience demonstrated a significant incidence of grade 3 cataracts, often bilateral, which could be due to a cohort with a median age of 76 years at diagnosis, corresponding to a baseline risk of age-related cataracts over 40% [ 11 , 12 ]. The available dosimetric data did not allow for correlation analysis in this study, but considering the low median dose at 0.1cc of the lens, the authors express reservations about affirming a clear association between the administered treatment and the development of cataracts.…”

Risk factors for Self-Reported Diagnosed Cataract among older adults in Poland. Findings from PolSenior2 Study.

“…Cataract is the leading cause of reversible blindness and visual impairment worldwide [1], including Poland [2,3]. Epidemiological studies have shown that cataract results from multiple contributing factors [1,4,5,6,7,8,9,10,11,12,13,14,15]. Risk factors for, and causes of, cataract include ageing, genetics, lifestyle exposure, behaviors, infections, various health conditions, and socioeconomic factors [1,4,5,6,7,8,9,10,11,12,13,14,15].…”
