RESUMO
PURPOSE: To estimate the prevalence of cataract in the middle-aged urban population and the relation between cataract and metabolic syndrome and metabolic syndrome components. METHODS: The survey was carried out in Kaunas City, Lithuania, from 2001 to 2002, according to WHO MONICA study protocol. The ophthalmologic investigation was performed for 1282 respondents (573 men and 709 women) aged 35-64 years. Cataract was defined at slit lamp using LOCS III method. Metabolic syndrome was defined by ATP III criteria. RESULTS: Cataract was found in 17.6% of men and 19.0% of women (p>0.05). Metabolic syndrome was detected in 19.5% of men and 25.7% of women (p<0.05). After distribution of persons into 10-year age groups (35-44, 45-54, 55-64), the prevalence of cataract and metabolic syndrome among men and women significantly increased with age. A relation between cataract and metabolic syndrome was found for men aged 55-64 years and for women aged 45-64 years: the prevalence of cataract in men with metabolic syndrome was 1.3 times higher (43.8% vs 32.9%; OR=1.59 [95% CI, 0.77-3.26]) and in women with metabolic syndrome 1.4 times higher (31.8% vs. 22.6%; OR=1.60 [95% CI, 1.03-2.49]) than in persons of the same age and sex without metabolic syndrome. For men aged 4-64 years cataract was significantly related to central obesity (OR=1.80 [95% CI, 1.01-3.20]) and for women aged 45-64 years cataract was significantly related to higher arterial pressure (OR=1.98 [95% CI, 1.21-3.25]), central obesity (OR=1.54 [95% CI, 1.01-2.35]), and elevated level of serum triglycerides (OR=1.86 [95% CI, 1.20-2.90]). CONCLUSIONS: The results of this study show that the prevalence of cataract in urban women 45-64 years of age with metabolic syndrome was significantly higher than in women of this age without metabolic syndrome.
