Abstract

PurposeThe purpose of the CAP (Creteil AMD PHRC-funded) Study was to analyze risk factors of exudative age-related macular degeneration (AMD) in a large French case–control population.Patients and methodsOne thousand and twenty-four patients with exudative AMD and 275 controls were recruited. Information about lifestyle, medical history, and dietary intake were collected. Associations of risk factors were estimated using logistic regression.ResultsAfter multivariate adjustment, CFH Y402H and ARMS2 A69S polymorphisms were associated with very high risk for exudative AMD (OR = 6.21 and OR = 11.7, respectively, p < 0.0001). Risk for exudative AMD was increased in current smokers (OR = 3.79, p = 0.0003) and former smokers having quitted since less than 20 years ago (OR = 2.30, p = 0.002), but not in former smokers having quitted since 20 years or more ago (OR = 0.81, p = 0.43). Heavy smokers (at least 25 pack-years) were particularly at risk (OR = 3.61, p < 0.0001). Use of cooking oils rich in omega 3 fatty acids was significantly associated with a reduced risk of exudative AMD (OR = 0.55, 95 % CI: 0.36–0.84, p = 0.006), as well as a high consumption of fruits (OR = 0.60, 95 % CI: 0.37–0.98, p = 0.04), but not the consumption of fish, vegetables or oils rich in omega 6. High waist circumference was associated with increased risk for exudative AMD (OR = 2.53, p < 0.0001), but not hypercholesterolemia, hypertension, or body mass index.ConclusionsThe CAP Study confirms major…

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
