Abstract
  • Main research question: How is seafood consumption influenced by overweight and health beliefs in a region of traditional high-level fish consumption? Materials and methods: A randomly drawn sample of women aged 45-69 years who live in Northern Norway answered a self-administrated questionnaire about eating habits, socioeconomic factors and questions related to health sent to them by mail; 7556 women answered the questionnaire (response rate 56.1%) analyzed by logistic regression methods. Findings: The mean consumption of seafood was 15 times a month. There were 46% of the respondents who were overweight, 77% agreed that food is important for health and 55% had a desire to reduce weight. Overweight women consumed less lean fish than normal weight women (OR=0.8). Fish consumption was not associated to the desire to reduce weight. However, a general healthy food consumption pattern was both a strong predictor for weekly fish consumption and for normal weight and for the desire to reduce weight. Very high family income was associated to higher fat fish consumption (OR=1.9) normal body weight and for the desire to reduce weight (OR=2.1). High fish consumption in childhood and the belief that food is important for health were both strong predictors high fish consumption (OR 2.1 and 1.4 respectively for lean fish). Kids <7 years in the household predicted processed fish consumption (OR=2.9) but not the beliefs that food is important for health, that is predicted by teenagers in the households (OR+1.4). Education predicted high fat fish consumption, while age was a strong predictor for high lean fish consumption (OR=1.88 for >60 years compared to 45-49 years). Main conclusion: Higher fish consumption was predicted the more consumers' believe and behave according to foods importance to health, but not by overweight or desire to reduce weight. High fish consumption in childhood and high level of education and income in the population was also predictors of high fish consumption. Promoting of seafood as a low calorie healthy food and improving the healthy aspects of processed fish products may increase seafood consumption. The consumption effect will most probably be strongest among consumers with highest education and income. Teaching kids and teenagers eating seafood improves seafood consumption as adult.
