In-Store Food Marketing Research
Innovative strategies to
market healthier foods and
de-market junk foods
Karen Glanz, PhD, MPH

In-Store Food Marketing
Deserves attention as a unique focus –
distinct from media marketing, digital
marketing, and package labeling
Shoppers/buyers are usually adults, but
they are often influenced by children
Significant Research Gaps
Little research on children
related to IN-STORE marketing
Lack of representation of diverse
population groups
(race/ethnicity, income, education)
Limited research on consumer
behavior & health in real-life
settings
CONCEPTUAL FRAMEWORK:
Marketing the 4 P’s
Price: coupons, specials, private label/store brands
* Promotion: In-store vs. out-of-store; signage; banners;
taste-testing; shopper marketing”; single- vs. cross-brand
promotion; store nutrition guidance systems
* Placement: Location of products in store; influence of
assortments (quantity and variety); placement on shelves;
quantity of facings/shelf-space; store layout
Products: Nutrient composition; packaging; health
claims; targeting markets; effects of color and naming
* Most robust in-store marketing intervention opportunities
Pilot Study in progress
(The Food Trust, U of Penna, Temple University)
GOAL: evaluate impact of in-store
marketing strategies to…
–
–
–
–
Increase sales of healthy children’s foods
Decrease sales of empty calories from energy-dense,
low-nutrient children’s foods
Be profitable or cost-neutral to retailers/manufacturers
Improve customer satisfaction & loyalty
Pilot test observational measure:
Grocery Marketing Environment Assessment
Product Category Focus
• Known role in excess weight or weight gain prevention
• Nutritional content {CALORIES} varies within category
• Child-relevant
• Strong brand competition
• Potential to be revenue-neutral for retailers
• Can increase healthy, decrease unhealthy,
and/or shift the balance
Cereal
Milk
Beverages (SSB/0-calorie)
Salty snacks
Frozen entrees
Frozen dairy desserts
Canned pasta
Frozen entrees
Healthy check-out aisles
Study Phases & Design
Review previous sales data (select products)
Consumer focus groups
Design interventions
Randomize stores (4 tx, 4 control)
Implement interventions 4-6 months
MEASURES
Weekly sales data, 1 yr pre, weekly, post-intvn
Intercept interviews
Observations
Grocery Marketing Environment Assessment
pre-post
MEASUREMENT
Needed!
Feasible measures of the
4 P’s for in-store food retail
environments (measures exist for products)
Separate dimensions (e.g., placement, promotion)
Composite ‘scores’ to prompt and evaluate change
Maximize objectivity (e.g., use sales data)
Clear, feasible, reliable, disseminable
FIRST-GENERATION MEASURES
GroPromo (Kerr, Sallis, Bromby & Glanz; in review 2011)
Measures placement and promotion for several
categories of foods
Studied in 3 neighborhoods in San Diego
Good inter-rater reliability
Discriminant validity
Criterion validity (compared to customer receipts)
Health Responsibility Index (Dibbs/NCC, 2004 in UK)
Nutritional content of store brand (sodium, fat, sugar)
Labeling information
In-store promotions (shelf space, less healthy snacks @ checkouts
Customer information & advice
Overall Score
Research Methods
Balance between internal & external validity
Controlled experiments
Advantages: determine causal effects, manipulate
variables of interest
Disadvantages: if done in lab settings they may
differ from real-life situations
Field studies & natural experiments
Advantages: closer estimate of real-world
effects
Disadvantages: expensive, hard to control
external factors & events
Design Approaches
(micro to macro)
“Micro” includes laboratory
experiments, often not in
real-world settings
“Meso” includes analogue
stores, with experiments
and/or observation
“Macro” is in real-world settings,
ideally sustainable
Balancing pros & cons: Controlled
experiments in real store settings
Uses advantages of previous two approaches
Where industry-researcher partnerships have
the most potential payoff
From a public health perspective
Maximizes scientific rigor + real-world
applicability
Can build on controlled/lab experiments
Better chance of dissemination &
sustainability over time
Issues to consider
and Opportunities to use
•
•
•
•
•
•
•
Will need to tackle the unhealthy options
Brand-based vs. health-based marketing
Loyalty card users
Slotting allowances
Displays and signage – in-store triggers
Audio and shopping-cart displays
Information: on-packages and elsewhere
Challenges
Working together – supermarkets (want people to buy
more) and public health researchers (want people to buy
less of common products)
Consumer price and value sensitivity (wanting more food
for their money)
Defining ‘categories’ for sales data isn’t as easy as it seems
Balancing industry’s profit motive, consumer desire for
value, & health experts’ goal to reducing childhood
obesity
