Knowledge and barriers relating to fish consumption in older Australians.

Among 854 Australians ≥ 51 years of age, this cross-sectional survey explored knowledge regarding finfish consumption, sources of information on fish and omega 3 fatty acids, what barriers limit finfish consumption and what factors predict its consumption. The survey consisted of a validated quantitative fish frequency questionnaire with additional questions on barriers and knowledge relating to finfish. Twelve percent of respondents consumed oily fish ≥ 2 times per week. Cost was the most frequently (37%) reported barrier for fresh finfish consumption. In multiple regression analysis, respondents' exposure to multiple sources of information (odds ratio (95% confidence interval): 1.135 (1.01, 1.28), who correctly identified the current recommendations for fish consumption; 1.87 (1.13, 3.07), agreed that fish improves general health; 3.57 (1.13, 11.30), and reported fewer barriers towards canned fish consumption; 0.59 (0.41, 0.84) were more likely to consume ≥ 2 servings of fresh finfish per week. Education and health programs need to be readily available highlighting current recommendations for fish consumption and how targets can be achieved. Meal plans with various finfish/seafood and amounts of omega 3 fatty acids required to achieve recommendations, and within a suitable budget, is likely to be an important strategy to target older consumers to increase consumption.
