[BDSP. Notice produite par INIST Gf8R0x0z. Diffusion soumise à autorisation]. The POLA (Pathologies Oculaires Liées à l'Age) Study is a population-based study of cataract and age-related macular degeneration and their risk factors being carried out among 2,584 residents of Sète, southern France, aged 60-95 years. Recruitment took place between June 1995 and July 1997. Cataract classification was based on a standardized lens examination by slit lamp, according to Lens Opacities Classification System III. This paper presents results obtained from cross-sectional analysis of the first phase of the study. In polytomous logistic regression analyses, an increased risk of cataract was found for female sex (cataract surgery : odds ratio (OR)=3.03 ; cortical cataract : OR=1.67), brown irises (cortical, nuclear, and mixed cataracts : OR=1.61), smoking (cataract surgery : OR=2.34 for current smokers and OR=3.75 for former smokers), known diabetes of 10 or more years'duration (posterior subcapsular, cortical, and mixed cataracts and cataract surgery : OR=2.72), use of oral corticosteroids for at least 5 years (posterior subcapsular cataract : OR=3.25), asthma or chronic bronchitis (cataract surgery : OR=2.04), cancer (posterior subcapsular cataract : OR=1.92), and cardiovascular disease (cortical cataract : OR=1.96). Decreased risk of cataract was found with higher education (all types of cataract and cataract surgery : OR=0.59), hypertension (cataract surgery : OR=0. (...)
