Background• Dietary patterns are associated with nutrition-related chronic
diseases such as obesity, diabetes, cardiovascular disease, and cancer
• Poor dietary patterns among adolescents and young adults in Canada

Primary Research ObjectiveTo investigate if and how young people in Canada comprehend and use serving size and %DV information on the current and
modified NFts when choosing and comparing foods.

STUDY 1 used qualitative methods to explore the process by which young people engage with, understand, and use serving size and %DV information on the current and modified NFts.
STUDY 2 consists of a quantitative survey with 2,000 participants between the ages of 16-24 years from across Canada.

STUDY 1Design Overview:
• Verbal Protocol + semi-structured interviews within randomized stimulus conditions and asked to “think aloud” while participating in 2 Behavioural Tasks
• 26 participants • 50% 16 – 18 years / 19 – 24 years• 50% Male / Female • June – August 2013

Task #1 – Hypothetical purchase situation• Price and taste are most important factors
when choosing foods.“Get more, get a better bang for my buck.”
• The nutrition information on the NFt considered when choosing foods varies between participants.
“I mean I don’t personally know too much about like the pros and cons of different vitamins, and different stuff.”
• Simple at-a-glance symbols and colours can support interpretation of nutrition information.
“There is a term next to calories that I noticed immediately when scanning the box. I have never seen both those terms before.”

Task #2: Functional Survey with NFts
“More than the other product.”
![Page 14: Nutrition Labelling: Understanding and Use of Nutrition Facts Tables among Young People in Canada Erin Hobin Public Health Ontario May 28, 2014 Erin.Hobin@oahpp.ca](https://reader036.vdocuments.net/reader036/viewer/2022062516/56649e585503460f94b51303/html5/thumbnails/14.jpg)
PublicHealthOntario.ca
Task #2: Functional Survey with NFts• Do not know what the daily recommended amount is for
different nutrients and were unable to use %DV information.
“I don’t know what the daily value is.”
• Using the same metrics (e.g., %DV) for positive nutrients (e.g., calcium) and negative nutrients (e.g., saturated fat) may cause confusion for participants.
“You should always get 100% DV.”
• Participants randomized to the NFt conditions with standard serving sizes performed significantly better on survey tasks requiring comparisons across products.
“More than the other product.”
• No sense of whether high amounts of saturated fat are a good or bad thing; however, participants randomized to the NFt conditions with simple descriptors or colour coded %DV information performed significantly better on survey task requiring interpretation of %DV information.
“High” indicates high amount.”

Key take-away message• Standard serving sizes across similar products can support
food choices and more prescriptive information leaves less for interpretation and places information into context.
![Page 16: Nutrition Labelling: Understanding and Use of Nutrition Facts Tables among Young People in Canada Erin Hobin Public Health Ontario May 28, 2014 Erin.Hobin@oahpp.ca](https://reader036.vdocuments.net/reader036/viewer/2022062516/56649e585503460f94b51303/html5/thumbnails/16.jpg)

Relevance• Aligned with several food-related
recommendations made in the Healthy Kids Report section 2.5.
• Results can provide evidence to support more effective regulatory changes to Nutrition Facts tables.
• Translate findings to communicating nutrition information on front-of-package and menu labelling initiatives.
• Guide school curricula.

Next Steps• Conduct Study 2 – online survey with
2,000 participants across Canada
• Expose participants to same 6 experimental conditions testing current NFT compared to standardized serving sizes and simple descriptors and colours to interpret %DV information
• Specific applications of NFt such as more prominent display of calories, including “added sugars” information
