PURPOSE: To estimate the prevalence of lens opacities in a group of elderly people and evaluate their relation with diverse risk factors. METHODS: Cross-sectional observational study of the cohort of all persons over the age of 64 years from an urban area and a rural nucleus of the province of Cuenca, Spain. Information on sociodemographic parameters and smoking was compiled using a structured questionnaire. A physical examination was made in which weight, height, and waist circumference were measured, and an ophthalmologic examination was made of visual acuity and lens opacities. Cataracts were classified using the method of the WHO cataract group. RESULTS: The study included 1155 subjects out of 1435 elderly persons who were invited to participate (response rate 80.5%). The prevalence of cataract in men was 69.2% and in women, 65.5% (p>0.05). The percentage of persons with aphakia/pseudophakia was 17.8% in men and 17.5% in women (p>0.05). In a logistic regression model, age, obesity of more than 35 kg/m2, and low educational level were associated with the presence of cataract or aphakia/pseudophakia. CONCLUSIONS: The prevalence of cataract in people over 64 years is similar to that of other countries, but the prevalence of subjects with previous surgery for cataracts is the highest reported in the literature. Age, body mass index of more than 35 kg/m2, and low educational level were associated with the probability of having cataracts or undergoing surgery for cataracts.
