d ucation It was concluded: ‘This study of twins provides further evidence that cigarette smoking increases risk while fish consumption and omega-3 fatty acid intake reduce risk of AMD’. Incident age-related maculopathy The objective of the second study was to assess longitudinal associations between dietary fat and incident age-related maculopathy (ARM) in an older, population-based, historical cohort.2 A total of 3,654 persons, 49 years or older, participated; of whom 2,335 (75.1 per cent of survivors) were re-examined after five years. Dietary data were collected from 2,895 people (79 per cent) at baseline by means of a semi-quantitative food frequency questionnaire to calculate dietary fat intakes. The results obtained showed that: • Participants with the highest versus lowest quintiles of n-3 polyunsaturated fat intake had lower risk of incident early ARM (odds ratio 0.41); AJPCPE CONTINUING PROFESSIONAL EDUCATION • a 40 per cent reduction of incident early ARM was associated with fish consumption at least once a week (odds ratio 0.58); • fish consumption at least three times per week could reduce the incidence of late ARM (odds ratio 0.25). No association between incident ARM and butter, margarine, or nut consumption was found. It was concluded: ‘A regular diet high in n-3 polyunsaturated fat, especially from fish, suggests protection against early and late ARM in this older Australian cohort. Our study could not confirm deleterious effects of higher polyunsaturated fat intakes reported by other clinic-based studies.’ 1. Seddon JM, George S, Rosner B.
