Life Style and Food Habits Questionnaire in the Portuguese Population Aged 55 or More

October 7, 2015 updated by: Rufino Silva, Association for Innovation and Biomedical Research on Light and Image

Life Style and Food Habits Questionnaire in the Portuguese Population Aged 55 or More.

The study population will be selected from the "Epidemiological study on the prevalence of Age related Macular Degeneration in Portugal" (Protocol N. CC-01-2009) where retinal photographic grading (current gold standard for AMD assessment) was performed to confirm AMD diagnostic. This study provides a population-based sample in which precise and contemporary information on the frequency of nutritional and lifestyle risk factors will be collected, enabling to evaluate whether the separate and/or joint effects of these factors, if found significant, are likely to have a major public health impact in terms of AMD.
