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 socio-ecological 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 PresentationPresentation of literature review from practitioner piece– Same message and wording in a

presentation format– Includes “notes’ for presenter– Includes all references

R2P Series

DistributionCurrent 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 low- energy-density than for people who simply ate low-fat foods.

Intervention 4: Increased Fruits and Vegetables withDecreased 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.

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 sugar-sweetened beverages (SSB) to caloric intake, the association of SSB and body weight, interventions to reduce SSB, contextual factors influencing what we drink.
