Adoption, implementation, and sustainability of early childhood feeding, nutrition and active play interventions in real-world settings: a systematic review. Int J Behav Nutr Phys Act 2023; 20:32. [PMID: 36941649 PMCID: PMC10029282 DOI: 10.1186/s12966-023-01433-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 03/05/2023] [Indexed: 03/23/2023] Open
Abstract
BACKGROUND Instilling healthy dietary habits and active play in early childhood is an important public health focus. Interventions supporting the establishment of nutrition and active play behaviours in the first years of life have shown positive outcomes and long-term cost-effectiveness, however, most are research trials, with limited evidence regarding real-world application. Implementation science theories, models and frameworks (TMFs) can guide the process of research translation from trial to real-world intervention. The application of TMFs within nutrition and active play intervention studies in early childhood (< 5 years) is currently unknown. This systematic review identified the use of TMFs and barriers/ enablers associated with intervention adoption, implementation, and sustainability in early childhood nutrition and active play interventions implemented under real-world conditions. METHODS Six databases were searched for peer-reviewed publications between 2000-2021. Studies were included if primary outcomes reported improvement in diet, physical activity or sedentary behaviours amongst children aged < 5 years and interventions were delivered under real-world conditions within a community and/or healthcare setting. Two reviewers extracted and evaluated studies, cross checked by a third and verified by all authors. Quality assessment of included studies was completed by two authors using the Mixed Methods Appraisal Tool (MMAT). RESULTS Eleven studies comprising eleven unique interventions were included. Studies represented low, middle and high-income countries, and were conducted across a range of settings. Five TMFs were identified representing four of Nilsen's implementation model categories, predominantly 'evaluation models'. Ninety-nine barriers/facilitators were extracted across the three intervention phases-Implementation (n = 33 barriers; 33 facilitators), Sustainability (n = 19 barriers; n = 9 facilitators), Adoption (n = 2 barriers; n = 3 facilitators). Identified barriers/facilitators were mapped to the five domains of the Durlak and DuPre framework, with 'funding', 'compatibility' and 'integration of new programming' common across the three intervention phases. CONCLUSIONS Findings demonstrate that there is no systematic application of TMFs in the planning, implementation and/or evaluation of early childhood nutrition and active play interventions in real-world settings, and selective and sporadic application of TMFs occurs across the intervention lifespan. This apparent limited uptake of TMFs is a missed opportunity to enhance real-world implementation success. TRIAL REGISTRATION PROSPERO (CRD42021243841).

Abstract
Background: Sustained implementation of moderate to high-intensity interventions to treat childhood obesity meets many barriers. This report uses the Centers for Disease Control and Prevention's (CDC's) Replicating Effective Programs framework to describe and evaluate the implementation of a 5-year health care-community collaborative program. Methods: Interviews with program leadership provided information on setting, organizational culture, program creation and adaptation, and costs. Administrative data were used for number of sessions and their characteristics; referrals; and 2018-2019 participant enrollment, attendance, completion numbers, and completer outcomes. Results: Preconditions for this program were high childhood obesity prevalence, and the complementary strengths of the health care organization (primary care treatment referral stream, population health orientation, alternative Medicaid funding) and the community organization (accessible space and time, staffing model, and organization mission). Preimplementation steps included collaborative design of a curriculum and allocation of administrative tasks. Implementation led to simultaneous deployment in as many as 17 community locations, with sessions offered free to families weekday evenings or weekends, delivered in English or Spanish. From 2018 to 2019, 2746 children were referred from nearly 300 providers, 832 (30.3%) enrolled, and 553 (66.3%) attended at least once, with 392 (70.8% of attenders and 47.1% of enrolled) completing the program. Outcomes in completers included improvement in %BMIp95 [-2.34 (standard deviation, SD 4.19)] and Progressive Aerobic Cardiovascular Endurance Run (PACER) laps [2.46 (SD 4.74)], p < 0.0001 for both. Evolution, including in referral process, Spanish program material and delivery, and range of ages, occurred continuously rather than at discrete intervals. Major system disruptions also affected the implementation. Maintenance of the program relied on the health care organization's administrative team and the collaboration with the community organization. Conclusion: This program's collaboration across organizations and ongoing adaptation were necessary to build and sustain a program with broad reach and positive health outcomes. The lessons learned may be helpful for other programs.

Abstract
This study investigated the policy processes related to the 2012 adoption of the Jamie's Ministry of Food programme by the Victorian Government in Australia. The aim was to provide insight into obesity prevention policy change processes to help strengthen future health promotion action. State-level government policy processes were examined through key informant interviews and a review of relevant documentation. Data were analysed using the Multiple Streams Theory and the Advocacy Coalition Framework in order to understand influences on relevant policy processes and strategies used by policy advocates to facilitate policy adoption. We found that policy adoption was facilitated by dedicated national funding for preventive health at that time, the relatively small number of stakeholders involved in the policy development process and the anticipated support for the programme by the general public due to the association with celebrity chef, Jamie Oliver. We identified that policy brokers aligned the policy with decision-maker ideologies and broader government objectives, and proactively managed potential criticisms. Evidence of intervention effectiveness was not a major driver of policy adoption. We conclude that, iven the complexity of policy processes for obesity prevention, multiple, reinforcing strategies are likely to be needed to facilitate policy change. Support for the adoption of obesity prevention policies is likely to increase when framing of policy options aligns with decision-maker values and has broad public appeal.

Abstract
Background: Health message framing, including gain or loss frames, can influence perceptions of child health messaging. It is unknown how characteristics such as political party and education may impact policymakers' message frame preference and perceived strength of child obesity messages. The purpose of this study was to examine preferred child obesity message frame, perceived strength of child obesity messages, and group differences among state policymakers. Methods: A cross-sectional online survey was administered in-person to state representatives and senators via electronic tablet between February and May, 2019, at a midwest State Capitol building. Participants were asked their message frame preference and perceived strength of child obesity messages related to long-term health, school, geographic region, military readiness, cost-savings, and the workforce. They were also asked who was responsible for preventing child obesity and strategies to prevent it. Data were analyzed descriptively and via chi-square tests for group differences. Results: One hundred fifteen state policymakers completed the survey. Participants overall favored gain-framed messages, which were perceived as stronger than loss-framed. Parents were viewed as most responsible overall for preventing child obesity, with Republicans (vs. Democrats; χ2 = 8.54; p = 0.008) and those with less education (vs. more; χ2 = 5.97; p = 0.029) perceiving them as more responsible (χ2 = 8.54; p = 0.008). Democrats viewed the food industry as more responsible (χ2 = 11.4; p = 0.001) than Republicans. Increasing physical activity, nutrition education, and fresh fruits and vegetables in schools were the most preferred prevention strategies. Conclusions: Child health advocates should consider using gain-framed messages related to child obesity when communicating with policymakers, and targeting their preferred strategies may enhance policy development.

Abstract
OBJECTIVES To describe outcomes of a 4-year physical activity (PA) and nutrition intervention (2013-2017) in Dove Springs, a low-income urban community in Texas. METHOD Go! Austin/Vamos! Austin is a place-based intervention targeting the built and social environments of PA and nutrition. Baseline and follow-up measures related to PA and nutrition were obtained from 357 parent-child dyads (final n = 236) in the intervention community and a control community. A three-level dose of exposure measure was created to indicate the amount of exposure to intervention activities across the 4 years. Pre-post changes in key outcomes by level of exposure and contrasts across "high exposure" and "no exposure" categories were obtained using repeated-measures regression, adjusting for important confounders. RESULTS "High exposure" adult participants showed consistently more favorable changes than "no exposure" participants across a variety of indicators, including positive perceptions and utilization of community PA resources, amount of moderate PA, utilization of retail outlets offering fresh produce, and measures of healthy eating. Few improvements were seen in child-level outcomes. CONCLUSIONS Community interventions can successfully improve health-promoting behaviors provided they ensure sufficient dose of exposure.

A longitudinal implementation evaluation of a physical activity program for cancer survivors: LIVESTRONG® at the YMCA. Implement Sci Commun 2020; 1:63. [PMID: 32885218 PMCID: PMC7427880 DOI: 10.1186/s43058-020-00051-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Accepted: 06/15/2020] [Indexed: 12/19/2022] Open
Abstract
Purpose Increased physical activity (PA) levels in cancer survivors are associated with decreased risk of recurrence and mortality as well as additional positive health outcomes. PA interventions have shown to be efficacious, though many lack translation to and sustainability in community settings. We used dimensions of the RE-AIM framework to evaluate LIVESTRONG® at the YMCA, a nation-wide community-based PA program for cancer survivors delivered at Ys. Methods This was a longitudinal study design using national LIVESTRONG at the YMCA data compiled between 2010 and 2018. Data is from all YMCAs who deliver LIVESTRONG at the YMCA, submitted by Program Directors to the YMCA-USA. We assessed reach (number of participants), adoption (associations offering the program), implementation (conducting 3 fidelity checks), and organizational level maintenance (associations recently offering program). We also examined relationships between organizational characteristics (years of program existence and association area household income) and program implementation factors with member conversion rates. Results As of 2018, LIVESTRONG at the YMCA has reached 62,044 survivors and 245 of the 840 (29.2%) of Y associations have adopted the program. Among the adopters, 91% were aware of fidelity checks; implementation of observational (62.3%), goal setting (49.9%), and functional (64.6%) checklists varied. Most (95.1%) adopters reported offering ≥ 1 LIVESTRONG session per year (organizational-level maintenance) and a facility-level mean membership conversion percentage of 46.9 ± 31.2%. Fewer years implementing the program and higher association area household income were significantly associated with a greater membership conversion rate vs their comparison. In a multiple regression model controlling for organizational characteristics, conducting the fidelity checks independently (observational, β = 8.41; goal-setting, β = 9.70; and functional, β = 9.61) and collectively (β = 10.82; 95% CI 5.90–16.80) was positively associated with higher membership conversion rates. Conclusions LIVESTRONG at the YMCA, in its early years, has shown promise for high reach, while adoption at more associations could be facilitated. Implementing fidelity checks along with organizational characteristics were associated with membership conversion rate. Identification of association-level strategies to increase reach, adoption, implementation, and maintenance may increase the impact of this community-based PA program.

Abstract
Background Connect for Health is an evidence-based weight management program with clinical- and family-facing components for delivery in pediatric primary care for families of children ages 2 to 12 years. We used the Consolidated Framework for Implementation Research (CFIR) to guide formative work prior to national implementation. The purpose of this study was to describe the process and results of stakeholder engagement and program adaptation. Methods We used mixed qualitative and quantitative methods to iteratively adapt and optimize the program by assessing needs and perspectives of clinicians and parents, as well as contextual barriers, facilitators, and organizational readiness for the uptake of the proposed program tools and implementation strategies. We conducted interviews with primary care clinicians from four health care organizations in Boston, MA; Denver, CO; and Greenville, SC, and used principles of immersion-crystallization for qualitative analyses. We also conducted surveys of parents of children with a body mass index ≥ 85th percentile. Results We reached thematic saturation after 52 clinician interviews. Emergent themes representing the CFIR domains of intervention characteristics, outer and inner setting, and process included (1) importance of evidence-based clinical decision support tools that integrate into the workflow and do not extend visit time, (2) developing resources that respond to family’s needs, (3) using multimodal delivery options for family resources, (4) addressing childhood obesity while balancing competing demands, (5) emphasizing patient care rather than documentation and establishing sustainability plans, and (6) offering multiple training methods that incorporate performance feedback. Of the parents surveyed (n = 400), approximately 50% were Spanish-speaking and over 75% reported an annual income < $50,000. Parents affirmed the importance of addressing weight management during well-child visits, being provided with referrals and resources, and offering multiple methods for resource delivery. Decisions about program modifications were made at the program and healthcare-system level and based on stakeholder engagement findings. Modifications included cultural, geographic, and target audience adaptations, as well as varied resource delivery options. Conclusions To ensure the fit between the Connect for Health program and national implementation settings, adaptations were systematically made through engagement of clinician and parent stakeholders to support adoption, sustainability, and health outcomes.

Scaling-up evidence-based obesity interventions: A systematic review assessing intervention adaptations and effectiveness and quantifying the scale-up penalty. Obes Rev 2019; 20:964-982.

Abstract
Maximizing the benefits of investments in obesity research requires effective interventions to be adopted and disseminated broadly across populations (scaled-up). However, interventions often need considerable adaptation to enable implementation at scale, a process that can reduce the effects of interventions. A systematic review was undertaken for trials that sought to deliver an obesity intervention to populations on a larger scale than a preceding randomized controlled trial (RCT) that established its efficacy. Ten scaled-up obesity interventions (six prevention and four treatment) were included. All trials made adaptations to interventions as part of the scale-up process, with mode of delivery adaptations being most common. A meta-analysis of body mass index (BMI)/BMI z score (zBMI) from three prevention RCTs found no significant benefit of scaled-up interventions relative to control (standardized mean difference [SMD] = 0.03; 95% CI, -0.09 to 0.15, P = 0.639 - I2 = 0.0%). All four treatment interventions reported significant improvement on all measures of weight status. Pooled BMI/zBMI data from prevention trials found significantly lower effects among scaled-up intervention trials than those reported in pre-scale-up efficacy trials (SMD = -0.11; 95% CI, -0.20 to -0.02, P = 0.018 - I2 = 0.0%). Across measures of weight status, physical activity/sedentary behaviour, and nutrition, the effects reported in scaled-up interventions were typically 75% or less of the effects reported in pre-scale-up efficacy trials. The findings underscore the challenge of scaling-up obesity interventions.
