Kothe - ASBHM - What do young people know

  1. 1. WHAT DO YOUNG PEOPLE KNOWABOUT AUSTRALIAN DIETARYGUIDELINES?Results from two studies EMILY KOTHE VANESSA ALLOM & BARBARA MULLAN
  2. 2. BACKGROUND› Australian dietary guidelines recommend that adults consume two servings of fruit and five servings of vegetables each day.› This recommendation has been widely promoted in the Australian community through the Go for 2&5 social marketing campaign.› Young Australians (19-24 years) are less likely than any other age group to consume adequate amounts of fruit and vegetables. 2
  3. 3. UNDERSTANDING CONSUMPTIONSTUDY ONE› AIM: - To investigate the specific factors relevant to healthy eating behaviours in Australian young adults using a qualitative design.› DESIGN: - 45 young adults participated in focus group discussions about fruit and vegetables. - Discussions lasted 1-2 hours and involved 5-7 participants. - All focus groups were transcribed verbatim and analysed using framework analysis. 3
  4. 4. UNDERSTANDING CONSUMPTIONSTUDY ONE› RESULTS: - Analysis identified a number of barriers to consumption that fell into the a priori coding frame. - Significant knowledge gaps and misunderstandings were also identified. - Participants reported feeling confused about dietary guidelines - Many groups could not correctly report dietary guidelines - Many participants were unsure what foods contributed to dietary guidelines - Participants repeatedly made comments that appeared reveal significant knowledge gaps relating to serving sizes 4
  5. 5. UNDERSTANDING CONSUMPTIONSTUDY ONE› CONCLUSION: - Most fruit and vegetable promotion campaigns assume that people have a certain level of knowledge about fruits and vegetables. - Young people may not know enough to understand - and adhere to - dietary guidelines 5
  6. 6. QUANTIFYING KNOWLEDGE GAPSSTUDY TWO› AIM: - To quantitatively investigate the fruit and vegetable related knowledge of a sample of Australian young people.› DESIGN: - One-hundred and six young adults (mean age = 19 years) completed a web- based questionnaire that assessed recall and understanding of Australian dietary guidelines for fruit and vegetable consumption. - Recall of the guidelines, serving size knowledge, and food knowledge were all assessed. 6
  7. 7. QUANTIFYING KNOWLEDGE GAPSSTUDY TWO› RESULTS: - Knowledge of Australian dietary recommendations was assessed using both unprompted and prompted methods. - Unprompted recall: - 43% of individuals correctly reported the RDI of fruit - 54% of individuals correctly reported the RDI of vegetables. - Prompted recall: - 48% of individuals correctly reported the RDI of fruit - 64% of individuals correctly reported the RDI of vegetables. - Only 9% of participants correctly reported the Australia dietary guidelines for both fruit and vegetable consumption. 7
  8. 8. QUANTIFYING KNOWLEDGE GAPSSTUDY TWO› RESULTS: - Serving size knowledge was assessed using a serving size approximation task. Participants were asked to report the serving size for two fruits and two vegetables (apple, grapes, carrot and lettuce) Correct Incorrect Don’t Know Apple 61 34 0 Grapes 41 47 0 Carrot 30 57 4 Lettuce 30 38 4 8
  9. 9. QUANTIFYING KNOWLEDGE GAPSSTUDY TWO› RESULTS: - Food Product Knowledge was assessed using a recipe task. Participants were provided with a recipe and asked to indicate which foods would contribute to their daily intake of fruit and vegetables. % of participants who correctly classified the ingredient Carrot 97 Celery 96 Potato 90 Turnip 86 Canned tomato 78 Onion 71 Tomato paste 23 9
  10. 10. QUANTIFYING KNOWLEDGE GAPSSTUDY TWO› CONCLUSIONS: - Young adults in study two appeared to have significant gaps in all three domains of fruit and vegetable related knowledge. - Only a small minority of individuals could report both the fruit and vegetable guidelines - Many participants could not accurately report serving sizes or correctly identify foods which contribute to their daily intake of fruit and vegetables. - Knowledge gaps were consistent with knowledge gaps and misconceptions revealed in study one. These knowledge gaps show the need for a fresh approach to fruit and vegetable promotion in this population. 10
