Clinical Trial Summary
There is a large body of literature regarding efficacious intervention strategies for
treating childhood obesity. Unfortunately, the degree to which efficacious programs have been
packaged for translation in micropolitan and surrounding rural areas is unclear-an important
issue when considering the prevalence of obesity is higher in rural areas when compared to
urban areas. Epstein's Traffic Light Diet (TLD) is likely the most studied pediatric weight
management intervention (PWMI) and has demonstrated efficacy across a wide range of
randomized controlled trials in children 6-12 years of age. Building Healthy Families (BHF)
is an adaptation of the TLD and has been implemented in a micropolitan city and achieved
clinically and statistically significant reductions in child BMI z-score (-0.27±0.22)-a
similar magnitude of effect relative to previous efficacy trials. The investigators have
created online resources for organizations interested in delivering PWMIs, training modules
for related interventions, and participant-facing program materials that could be combined
into a 'turn-key' approach for communities interested in reducing childhood obesity to adopt,
adapt and sustain it in other micropolitan/rural communities. The primary aim is to
collaboratively refine and develop an intervention package for the BHF that includes
materials necessary for others to implement the intervention in new metropolitan/rural
locations. The second aim is to perform a rigorous, mixed-methods pilot implementation study
using an innovative community application process to identify 4 to 8 new communities to pilot
test the utility of the packaged PWMI and training materials while determining factors that
predict adoption, implementation and sustainability. The investigators will also use a
learning collaborative implementation strategy to improve implementation fidelity and local
context and facilitation capacity in communities interested in delivering BHF. The third aim
is to use the pilot evaluation data and results of the sustainability action plan to refine
program and training materials and develop a dissemination plan to move the program to other
communities. The approach will use an implementation research explanatory process and outcome
model to test hypotheses related to implementation and sustainability, engaging community/
clinical partners in the implementation and sustainability process, and evaluate outcomes at
both the individual and organizational level.
Description:
Since the early 1980s, a number of efficacious pediatric weight management interventions
(PWMI) have been developed to reduce child weight status. Epstein's Traffic Light Diet (TLD)
is likely the most studied PWMI and has demonstrated efficacy across a wide range of
randomized controlled trials in children up to and older than 12 years of age. This work and
the majority of efficacious PWMI have been based in large urban areas delivered through a
hospital or medical center and the most recent childhood obesity treatment recommendations do
not address geographically underserved audiences or settings where all members of an
interdisciplinary team may not exist. As a result, there is no information on the degree to
which evidence-based PWMIs have been translated into micropolitan (cities<50,000) and rural
settings. This is an important issue when considering the prevalence of obesity is higher,
socioeconomic status and access to preventive healthcare is lower, and 20% of the nation's
populations reside in rural areas based on the most recent census data. A related issue is
the potential mismatch between the resources and expertise used to deliver research and
hospital-based PWMIs in urban, when compared to micropolitan and rural, areas. Thus,
adoption, implementation, and sustainability may be limited in micropolitan and surrounding
rural areas unless adaptations are made that leverage multiple systems within the community
that interact with families and children and strategies include a balanced focus on reach and
effectiveness to increase the likelihood of having a public health impact. To address these
issues the research team has implemented an adapted version of the TLD in Kearney, Nebraska,
developed and used training approaches for PWMI for underserved micropolitan settings, and
conducted a number of implementation trials focused on planning for, and evaluating, PWMI
reach, effectiveness, adoption, implementation and maintenance (RE-AIM). This includes
research examining models of participant identification and engagement within settings where
a large proportion of children are screened for obesity-schools and primary care pediatric
clinics. Building Healthy Families (BHF), the investigators' TLD adaptation, includes the
required or more contact hours through regular and frequent in-person contact with families
and leverages the expertise and time of health professionals from a variety of local
organizations. BHF has been implemented locally and successfully achieved clinically and
statistically significant reductions in child BMI z-score (-0.27±0.22). Through collaborative
efforts the research team has developed online resources for organizations interested in
delivering PWMIs, training modules for related interventions, and participant-facing program
materials that could be combined into a 'turn-key' approach for communities interested in
reducing childhood obesity. The investigators preliminary work demonstrates that the adapted
TLD intervention can achieve a similar magnitude of effect relative to previous efficacy
trials, that the associated training materials and approaches can result in a high level of
implementation fidelity, and that ongoing program adaptations to address local needs can be
made. To date, the research team has not combined all of these approaches and materials as a
turn-key package that could be adopted, adapted, and sustained in other micropolitan/rural
communities.
The first aim is to collaboratively refine and develop an intervention package for the TLD
that includes all of the materials necessary for others to implement the intervention in new
micropolitan and rural locations. The second aim is to perform a rigorous, mixed-methods
pilot implementation research study using an innovative community application process to
identify 4 to 8 new communities to pilot test the utility of the packaged PWMI and training
materials when coupled with a learning collaborative facilitation strategy and sustainability
action planning process in supporting PWMI adoption, implementation, and sustainability when
compared to receiving access to the packaged program and training materials alone. Additional
outcomes will include start-up and ongoing costs while tracking intervention reach,
representativeness, and effectiveness in reducing and maintaining child weight status
relative to a matched cohort. The third aim is to use the pilot evaluation data and results
of the sustainability action plan to refine program and training materials and develop a
dissemination plan to move the program to other communities.
To complete these aims the investigators will engage an existing partnerships that includes
local schools and pediatricians in Kearney, NE and the Great Plains IDeA Clinical and
Translational Research Network Community Advisory Board who has identified childhood obesity
treatment, particularly in rural areas, across North Dakota, South Dakota, and Nebraska as a
priority. As is recommended, the approach will use an implementation research explanatory
process, and outcome model to test hypotheses related to implementation and sustainability,
engaging community/clinical partners in the implementation and sustainability process, and
evaluate outcomes at both the individual and organizational level. Specifically, the
Promoting Action on Research Implementation in Health Services (PARIHS) Framework will be
used as the explanatory model and the RE-AIM framework to track individual reach,
representativeness, effectiveness and organizational cost, adoption, implementation, and
sustainability.
