Food consumed away from homehas poor nutritional value1

Increased consumption of fast food associated with becoming overweight or obese.2,3

One quarter of the Canadian food dollar is spent on food away from home.4

Background

3

Menu labelling is currently mandatory in several US jurisdictions

United States will implement menu labelling federally in 2014 – via Patient Protection and Affordable Care Act

Canada has no mandatory menu labelling– Informed Dining voluntary program in BC – Government of Ontario announced Healthy Eating

Decisions Made Easy Act

Background

5

Evidence for menu labelling is mixed

Reviews suggest little impact at a population level5,6,7

• Some impact upon population subgroups• Impact varies upon settings

Little literature examining menu labeling in a Canadian context

The Ottawa Hospital Menu Labelling Program

6

Developed by Nutrition and Foodservices team with support from clinical nutrition team and external experts.

Identified an opportunity to implement a new menu labelling program with digital menu boards during renovations at the Civic hospital

Intervention components 5 digital menu boards with nutritional values for

calories, sodium, saturated fat and total fat.

7 Information provided for most food items

Civic Cafeteria Jan 2011

8

Intervention components

Health logo for items that meet the developed nutritional standards.

Educational campaign at the entrance to the seating area.

2, 085 exit interviews– Wave 1 n=1,003– Wave 2 n=1,082

10 minute intercept survey• Food ordered in the cafeteria• Noticing and use of menu labelling

Methods

Nutritional analysis of food ordered and consumed

Nutrition information obtained from The Ottawa Hospital Nutrition Services (using C-Bord)

Several estimations made:• Items from the salad bar• Items lacking adequate description

16

Methods

Analysis

3 primary outcomes• Noticing nutrition information• Using nutrition information• Nutrient consumption

Regression models used to test differences• Wave• Site

17

Analysis

Socio-demographics • age, gender, ethnicity, income, education, BMI

Consumer and behavioural demographics • consumer type, frequency of visiting the

cafeteria, use of nutrition labels when shopping for food, frequency of eating out, self-reported general health, and dieting behaviour in the previous year
