  1. Consumption of seafood -The influence from overweight and health beliefs. By Torbjorn Trondsen, T. Braaten, E. Lund and AE Eggen University of Tromso

  2. Main research question: • How is seafood consumption influenced by overweight and health beliefs in a region of traditional high-level fish consumption? Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  3. Materials and methods: • A randomly drawn sample of women aged 45–69 years who live in Northern Norway • 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 estimating Odds Ratio Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  4. Exploratory study. Relationships for investigation • Final model 45 significant independent variable measures Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  5. Characteristics of sample • Mean consumption of seafood 15 times a month • Lean fish (Cod, haddock etc.) 8/month • Processed fish (cakes, sticks, puddings, etc.) 5.2/month • Fatty fish (salmon, trout, mackerel, etc.) 1.8/month • 46% of the respondents were overweight • 77% agreed that food is important for health • 55% had a desire to reduce weight Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  6. Health, overweight and seafood consumption Food important for health Fish in childhood Education length Age > 50-59 + + Teenagers in household + _ + + Healthy food consumption pattern Fish consumption + + Very high income _ _ _ Age >50 Health status + Overweight + + + Desire to reduce weight _ Age >60 Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  7. Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  8. Belief about health and food • H1. Fat and lean fish, but not processed fish consumption, are associated with the perception that food is important for health • The belief that food is important for health as predictors for • Fatty fish consumption (OR=1,24) • Lean fish consumption (OR=1.38) Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  9. Fish consumption and Overweight (BMI>25) • H2. Fish consumption is lower among overweight women than among normal weighty, but fish is not on the weight reducing diet • Overweight women consumed less lean fish than normal weight women (OR=0.8) • Fish consumption was not associated to the desire to reduce weight • Consumption of vegetable and fruit (5-a-day), smoking and physical activity predict for the desire to reduce weight Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  10. Fish consumption and healthy food consumption pattern • H3. Fish consumption increases among consumers changing to a healthy food consumption pattern • A healthy food consumption pattern measured as: • Consumption of 5-a-day vegetables and fruit, fish oil daily, fat spread on bread, food supplements daily, wine weekly • a strong predictor for • weekly fish consumption • normal weight • the desire to reduce weight Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  11. Education and age • H4. Fish consumption increases with increasing age and education length • Education predicted • high fat fish consumption • Age a strong predictor for high lean fish consumption (OR=1.88 for >60 years compared to 45-49 years) Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  12. Income as predictor • H5.Fish consumption increases when families grow into very high-income levels • Very high family income was associated to • higher fat fish consumption (OR=1.9) • normal body weight • the desire to reduce weight (OR=2.1) Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  13. Childhood and Children in household • H6. High fish consumption in childhood increases both lean and fat fish consumption as adult, while children in household increases the consumption of processed fish • High fish consumption in childhood (3+ a week) • a strong predictors for • Lean fish consumption (OR=2.1) • Processed fish consumption (OR=1.25) • Kids <7 years in the household predicted • processed fish consumption (OR=2.9) • Teenagers in the household (not smaller children) predicted the beliefs that food is important for health (OR=1.4) Trondsen T:Seafood, overweight and health beliefs. IIFET 2002

  14. Main conclusions • Higher fish consumption if • 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 • Promoting seafood as a low calorie healthy food • Improving the healthy aspects of processed fish • Teaching kids and teenagers eating seafood improves seafood consumption as adult • The strength of these predictions • constrained by market barriers • purchasing power, supply, products, prices etc Trondsen T:Seafood, overweight and health beliefs.
