DNPA’s Weight Management
Research to Practice Series
The R2P Series
Translating science to practice
R2P Series
• The R2P series is a way to address the
need for a user-friendly summary of
the evidence supporting key topics in
weight management.
• Each installment in the series consists
of two related components.
R2P Series
Purpose
– DNPA responded to requests from funded
states and partners for a user-friendly way to
stay current on existing evidence supporting
relevant weight management topics.
– Also interested in ways to address these
topics in practice.
– Started out with DNPA’s main strategies and
expertise and are beginning to expand to
other topic areas working with other divisions.
R2P Series
Process
– Scientific review and synthesis of the
literature
– Consumer tool developed, as appropriate
– Clearances - CDC and Dietary Guidelines
– Graphics
– Final product posted on website and
promoted at professional conferences and
through email listservs
– Professional graphics files available for
printing
R2P Series
Structure
– Practitioner piece
• Research brief (5 to10 pages) summarizing
evidence, not a comprehensive review
– Consumer Tool
• Shorter (4 to 6 pages) of consumer messages
and easy “how to” ideas
– Power point presentations
• Presentation of the practitioner piece for
practitioners to use with colleagues, funders,
partners, etc.
R2P Series
Structure of Practitioner Piece
– Background – genesis of topic
– Build case of available literature
• Review of primary sources
• Review of reviews
– Identify research gaps
– Practice section of practitioner piece
• General tips that address all levels of the socioecological model
• References included
R2P Series
Structure of Consumer Tool
– Translate message of Practitioner piece
into consumer friendly messages without
changing the scientific basis
– Brochure with “tips”
– Game board
– Gathering of resources, i.e. links to other
websites
– Open structure to fit each topic best
R2P Series
Structure of Power Point Presentation
Presentation of literature review from
practitioner piece
– Same message and wording in a
presentation format
– Includes “notes’ for presenter
– Includes all references
R2P Series
Distribution
Current plans for distribution:
• Posting on DNPA website
• Sending out link through listservs
• Presentations at national conferences
• Professional Organizations
• Printing – when funds are available and with
partners
• Availability of print ready files
R2P Series
Excerpts from current practitioner and
consumer pieces:
1. Can eating fruits and vegetables help
people manage their weight?
2. Do increased portion sizes affect how
much we eat?
3. Does drinking beverages with added
sugars increase the risk of overweight?
R2P Series
Can eating fruits and vegetables help
people manage their weight?
• Concludes that replacing foods of high
energy density with foods of low energy
density, such as fruits and vegetables, can
be an important part of a weight
management strategy.
• Topics covered include: energy density and
volume of food and dietary interventions

Can eating fruits and
vegetables help people
to manage their weight?
There are many proposed strategies for losing
or maintaining weight.
This presentation looks at only one strategy:
substituting low-energy-dense fruits and
vegetables for foods with high energy density in
order to lower the number of calories consumed.
References to all studies are in “Can fruits and vegetables help people to
manage their weight?” in the CDC Web site:
www.cdc.gov/nccdphp/dnpa and in the notes in this electronic
PowerPoint presentation.
A literature review* found similar findings:
 Short-term studies (< 1mo.): Low-energy-dense foods
promoted feeling full, reduced hunger, and provided
fewer calories.
 Long-term studies (> 1mo.): Low-energy-dense foods
promoted moderate weight loss.
 Studies lasting longer than 6 months: Weight loss was
three times greater for people who ate foods of lowenergy-density than for people who simply ate low-fat
foods.

Intervention 4: Increased Fruits and Vegetables with
Decreased Fat Intake*
 Participants consumed a daily diet that included specific
amounts of fruits, vegetables, juice and fiber, and
provided 15%-20% of energy from fat.
After 1 year:
 Energy-adjusted intake of vegetables and dietary fiber,
but not fruit, was associated with a decrease in body mass
index (BMI).
 A decrease in percent energy from fat was not associated
with a drop in BMI.

evidence from a randomized controlled trial. Cancer 2001;91:25-34.
Research Review
 Very few studies examined a direct relationship between
eating fruits and vegetables and losing weight.
 Some studies had few participants.
 Many studies focused on fruits and vegetables in the
context of treating high blood pressure or cardiac
disease—but also reported on weight loss.
 Some studies examined the short-term impact of eating
fruits and vegetables on energy intake.
R2P Series
Do increased portion sizes affect how much
we eat?
• Examines the science that underlies the
notion that large portion sizes have
contributed to weight gain among
Americans.
• Topics covered include: trends in increasing
portion sizes, portion size affects how much
we consume during an eating occasion, and
assessing amount of intake.

Does drinking beverages with added sugars
increase the risk of overweight?
An overview of the following are provided:
added sugar and the contribution of sugarsweetened beverages (SSB) to caloric
intake, the association of SSB and body
weight, interventions to reduce SSB,
contextual factors influencing what we
drink.
