A Comprehensive Planning Framework for Designing Effective Physical Activity Interventions in Youth.

BACKGROUND: Effective physical activity (PA) interventions are needed to counter the insufficient and declining levels of PA in youth. These require an updated, comprehensive planning framework that consolidates recent decades of progress in promoting PA in young children, children, and adolescents. Effective PA interventions require program planning and conceptual model development that target a coordinated and multilevel set of age-specific PA determinants. Accordingly, this paper presents a comprehensive planning framework that researchers can use to design intervention research to promote PA in youth. METHODS: The first author conducted targeted searches through Google Scholar to compile PA models/frameworks/guides applicable to youth, a comprehensive set of PA determinants, and determinant-linked strategies to promote PA focusing on review articles. The information was summarized in tables, synthesized, and used to create a planning framework, all of which were reviewed by coauthors. RESULTS: The APPLE Framework for Planning PA Opportunities for Youth (APPLE = Age, PA focus, Place and time, Leverage relevant influences and strategies, and ensure Enjoyable PA opportunities) incorporated all core elements from targeted reviews to create a comprehensive planning framework. The APPLE Planning Framework has a set of questions/prompts that guide the intervention planning process and conceptual model templates to organize planning efforts for designing intervention research. CONCLUSIONS: The APPLE Framework for Planning PA Opportunities for Youth will enable researchers to develop comprehensive conceptual models to guide the design of PA interventions for youth. Future research should refine the model and its components to enable PA intervention research in youth to move forward.

Determinants of Change in Physical Activity in Children during the Transition from Elementary to High School.

INTRODUCTION: Effective public health interventions targeting factors that influence physical activity are urgently needed to reduce the age-related decline in physical activity in youth. The purpose of this study was to identify associations between physical activity and a set of potential influences on physical activity in children as they transition from elementary to high school. METHODS: Participants were 951 children from South Carolina school districts who completed outcome and independent variable measures on at least two time points from the 5th to 11th grades in 2010-2017. The primary outcome variable was physical activity, measured by accelerometry. Independent variables included a comprehensive set of variables in the child, parent/home, school, and community domains. Children, parents and school administrators, and staff completed questionnaires to assess psychosocial and home, school, and neighborhood environmental influences. Growth curve analyses identified independent variables associated with physical activity over time, either as a main effect or as an interaction with age. RESULTS: As main effects, self-efficacy, self-schema, sport participation, weekday outdoor hours, importance of child participating in sports and physical activity, safe to play outside, and Physical Activity Resource Assessment weighted score were positively associated with physical activity. The associations between physical activity and enjoyment motivation, appearance motivation, weekend outdoor time, and home equipment exhibited significant interactions with age. Enjoyment motivation influenced physical activity during the earlier years, whereas the remaining three variables influenced physical activity in the later years. CONCLUSIONS: Interventions should target multiple domains of influences that may vary by age.

Association of physical activity, sedentary behavior, diet quality with adiposity: a longitudinal analysis in children categorized by baseline weight status.

BACKGROUND/OBJECTIVES: Childhood obesity rates have increased in recent years. The effectiveness of future public health interventions to reduce childhood obesity will be enhanced by a better understanding of behavioral factors that influence adiposity in children as they transition from childhood to adolescence. The purpose of this study was to examine whether initial weight status modifies the longitudinal associations of physical activity, sedentary behavior, and diet quality with changes in adiposity over time. SUBJECTS/METHODS: A total of 658 children (45% boys) were stratified into 3 groups based on 5th grade BMI percentiles ( < 85th, 85-95th, > 95th) and followed from 5th grade to 6th and/or 7th grade. Study variables, including fat-mass-index (FMI), moderate-to-vigorous physical activity (MVPA), diet quality, and sedentary behavior, were measured at 5th, 6th, and/or 7th grades. Separate growth curve models were conducted within each weight status group to examine the associations between MVPA, sedentary behavior, diet quality and adiposity, operationalized as FMI. All models controlled for sex, maturity offset, race, and parent education. RESULTS: Of the 658 children, 53% were classified with normal weight at baseline, 18% with overweight, and 29% with obesity. Associations between MVPA, sedentary behavior, diet quality and FMI varied within each weight status group. MVPA was negatively associated with adiposity (FMI) for all weight status groups. Diet quality and sedentary behavior were associated with adiposity only in children with obesity at baseline; neither diet quality nor sedentary behavior was associated with FMI for those with overweight. CONCLUSIONS: MVPA was negatively associated with adiposity (FMI) in all weight status groups, suggesting that MVPA may protect against higher adiposity. Sedentary behavior and diet quality were associated with adiposity only in children with obesity at baseline; neither sedentary behavior nor diet quality was associated with FMI for children with overweight.

Understanding Commitment of Local Food Banks, Faith-Based Organizations, and Schools to Provide Nongovernment Food Programs.

Background: Nongovernment food assistance is typically provided to families by faith-based organizations, schools, and food banks. Community organizations appear to be strongly committed to these programs, but little is known about the basis for this commitment. Objectives: The aim of this study was to examine the values and identities of community organizations to understand the reasons for their commitment to providing nongovernment food assistance. Methods: Thirty-three in-depth interviews were conducted with 36 leaders at faith-based organizations (19 participants), schools (14 participants), and a local food bank (3 participants) in South Carolina. Observations were made, and informational documents (e.g., flyers and pamphlets) were reviewed. Thematic coding using the constant comparative method was guided by the policy concepts of organizational perspectives, values, and identities. Results: Nongovernment food programs offered participants volunteering opportunities to become involved with community organizations, which in turn increased financial support for the sustainability of these programs. School participants regarded themselves as a mechanism through which food programs were provided because of their commitment to students and believed they have limited capacity to make proposals to influence the food programs. Seeking to improve the well-being of the community by ending hunger was not the primary value on which organizations focused; instead, it was the process of fulfilling other values (e.g., forming or maintaining relationships within the community), maintaining identity, and appealing to their participants that strengthened their commitment to nongovernment food programs. Conclusion: Nongovernment programs are meant to be a solution to food insecurity complementary to government programs. Commitment to nongovernment programs fulfills organizational identities, wants, and assumptions, but a consequence of commitment to food programs, derived from fulfilling other values, is that the roots of hunger in a community become obscured and alternative solutions are ignored or rejected.

Longitudinal changes in domains of physical activity during the transition from elementary school to high school in the U.S.

OBJECTIVES: To describe patterns of age-related change in self-reported physical activity domains within a heterogeneous sample of boys and girls in the U.S. transitioning from elementary to high school. DESIGN: Prospective cohort study. METHODS: Participants included n = 644 children recruited in 5th grade (10.5 ±â€¯0.5 years old, 45 % female) who completed the Physical Activity Choices survey at least twice over 5 time points (5th, 6th, 7th, 9th and 11th grade). Participants' self-reported physical activities were categorized into organized and non-organized activities, and a comprehensive variable was created as the product of the total number of physical activities reported in the past 5 days, the number of days spent in each activity, and the total time spent in each activity. Descriptive statistics and growth curve models (controlling for covariates) for the total sample and by sex were examined for total, organized, and non-organized physical activities from ages 10 to 17. RESULTS: There was a significant age by gender interaction (p < 0.05) for time spent in non-organized physical activities. Specifically, both sexes had similar patterns of decline before age 13, while boys increased after age 13 and girls declined and then maintained. In contrast, boys and girls declined in organized physical activities from ages 10 to 17 (p < 0.001). CONCLUSIONS: We observed stark differences in the age-related change between organized and non-organized physical activities and marked differences in the patterns of non-organized physical activities between boys and girls. Future research should examine physical activity interventions that consider age-, sex-, and domain-specific physical activity options for youth.

A process for converting an in-person training to increase church capacity to implement physical activity and healthy eating practices and policies to an online format.

The implementation of evidence-based public health programs into practice is critical for improving health, but trainings for organizational change agents are often not scalable. To describe the process of converting a training that targets faith-based organizational capacity development from an in-person to an online format. We engaged in an iterative process to convert the training delivery mode from in-person to online that included assessing stakeholder support, consulting the literature on best practices, seeking a design team, consolidating content, designing engaging lessons, and building an online site. Feedback from end-users and other audiences was incorporated throughout. Pilot participants with characteristics like intended training users were then recruited via community and faith-based partner networks. They rated their agreement with statements about the effectiveness as well as design and functionality of each lesson and the overall training (1 = strongly disagree, 5 = strongly agree) and participated in a structured follow-up interview. Nine pilot participants (representing 9 churches in 7 states; 6 African American, 5 with health ministries) rated the online lessons favorably (all ratings ≥ 4.5). Most (90.4%) perceived the lesson duration to be "just right" and spent 52.5 ± 9.9 minutes/lesson. Participants evaluated the overall training positively (all ratings ≥ 4.7). Lesson content, resources, multimedia, and program ideas were most-liked aspects of lessons, while content, staff responsiveness, discussion board, and pace were most-liked aspects of the overall training in open-ended and interview responses. This paper shares a replicable process for converting training modalities from in-person to online with the goal of increased scalability.

A Summary of One Research Team's Contributions to Understanding Physical Activity Behavior in Children and Youth.

Schools are well-positioned to provide physical activity opportunities to help youth achieve the recommended 60 or more daily minutes of moderate-to-vigorous physical activity. The Children's Physical Activity Research Group (CPARG) at the University of South Carolina has focused on understanding physical activity in school-aged youth for 30+ years. The purpose of this article was to critically review (CPARG) contributions to the field in school settings and school-age youth. We reviewed 127 published CPARG articles from six research projects conducted between 1993-2019. The review was guided by questions in five categories: measurement of physical activity and its determinants, characteristics of physical activity behavior, correlates/determinants of physical activity, physical activity interventions, and race/ethnicity and physical activity. Results were summarized by question and synthesized across categories. CPARG contributions included assessing physical activity levels, patterns, forms, and contexts; identifying and measuring physical activity correlates/determinants; and conducting school-based physical activity interventions. Identifying multiple domains of physical activity determinants enables researchers and practitioners to select/design age-appropriate, valid, and reliable instruments to assess determinants. Focusing on determinants enables them to create effective physical activity interventions, environments, programs, and policies in schools. These efforts must address race/ethnicity differences, ensuring that measurement instruments and intervention strategies are culturally appropriate.

Influence of implementation strategies on implementation outcomes in a statewide dissemination of Faith, Activity, and Nutrition (FAN).

Faith-based organizations are promising settings for implementation science because they can reach populations bearing a disproportionate burden of chronic disease. This study examined how implementation strategies influenced implementation outcomes in Faith, Activity, and Nutrition (FAN) statewide dissemination. Ninety-three (9%) of 985 invited churches enrolled; 91 (98%) and 83 (89%) completed baseline and 12-month assessments. Community Health Advisors trained and provided phone technical assistance to church committees, led by a FAN coordinator. Church committees were charged with developing plans and installing healthy eating (HE) and physical activity (PA) policies, opportunities, messages and pastor support (implementation outcomes). Structural equation modeling examined how implementation strategies influenced implementation outcomes. Nearly all (99%) FAN coordinators and 60% of pastors attended training, 57% of committees submitted program plans and 51%/54% (HE/PA) of committees met 'every few months'. Statistically significant (P < 0.05) model paths showed positive influences of strategies on implementation outcomes: pastor training on HE and PA pastor support; plan completion on HE and PA messages, PA policies and opportunities as well as FAN committee meetings and committee meetings on HE pastor support, HE policies, PA opportunities and HE and PA messages. This study advances implementation science and provides a model applicable to organizations such as worksites and schools.

The Faith, Activity, and Nutrition (FAN) dissemination and implementation study: changes in and maintenance of organizational practices over 24 months in a statewide initiative.

BACKGROUND: Few studies have examined the impact of ecological health promotion interventions on organizational practices over time, especially in faith-based settings. This statewide dissemination and implementation study examined change in organizational practices and their predictors across a 24-month period, as well as maintenance of change. METHODS: Using a pre-post quasi-experimental design, church coordinators from 92 United Methodist Churches in South Carolina (42% predominantly African American congregations) completed surveys at baseline, and immediate, 12-, and 24-months post-training regarding physical activity (PA) and healthy eating (HE) organizational practices consistent with the Faith, Activity, and Nutrition (FAN) program (opportunities, policies, pastor support, messages) and possible predictors. The study was guided by the RE-AIM framework and the Consolidated Framework for Implementation Research (CFIR). Mixed model repeated measures analyses examined change in organizational practices over time. Regression models examined CFIR predictors of 24-month PA and HE organizational practices, controlling for baseline practices. Churches were also classified as maintainers (implemented at 12 and 24 months), non-sustained implementers (implemented at 12 but not 24 months), delayed implementers (implemented at 24 but not 12 months), and low implementers (implemented at neither 12 nor 24 months) for each FAN component. RESULTS: PA and HE organizational practices increased over time (p < .0001). CFIR domains (and constructs within) of intervention characteristics (adaptability, relative advantage, cost/time), inner setting (relative priority, organizational rewards, readiness, congregant needs), characteristics of the implementer (self-efficacy, perceived benefits), and implementation process (engaging opinion leaders, engaging champions) were important predictors of 24-month PA and HE organizational practices. Over half of churches implementing PA policies, PA messages, HE policies, and HE opportunities at 12 months were maintainers at 24 months, and one-third were maintainers for PA opportunities, HE messages, and PA and HE pastor support. Furthermore, 16% of 12-month non-implementers were delayed implementers at 24 months for PA policies and 31% were delayed implementers for HE policies. CONCLUSIONS: This study makes important contributions to the faith-based health promotion literature by including a large sample of churches, testing an ecological intervention approach, and assessing organizational practices over a 24-month period. Study findings can guide technical assistance and program adaptations over time. TRIAL REGISTRATION: This study was registered in clinicaltrials.gov NCT02868866 on August 16, 2016.

Longitudinal association of biological maturation with physical activity behaviors in girls transitioning from 5th to 7th grade.

INTRODUCTION: This longitudinal study determined if social cognitive variables influence physical activity in girls stratified on the basis of maturity status. METHODS: Participants attended South Carolina public schools (Mage in 5th grade = 11.1 years) and included a cohort of 529 girls who provided physical activity data in the 5th grade and in 6th and/or 7th grade. The measure of maturity status was age at peak height velocity (APHV) estimated from maturity offset when the children were in the 5th grade. The Earlier Maturity (EM) group included girls whose APHV was one standard deviation or more below the mean APHV for the full sample. All other girls were placed in the Later Maturity (LM) group. Physical activity was assessed at each time point via accelerometry. Social-cognitive variables were assessed at each time point by a questionnaire measuring self-efficacy, enjoyment, competence, appearance, fitness, and social motives for physical activity. Growth curves for the total, Earlier Maturing, and Later Maturing groups assessed relationships between physical activity over time and time-varying social cognitive variables. RESULTS: Physical activity was lower in the Earlier Maturing group and was positively associated with self-efficacy and enjoyment motivation in the total group. These relationships were observed in the 5th grade and maintained through 7th grade. In the Later Maturing group, we observed positive relationships between physical activity and self-efficacy, enjoyment and competence motivation. CONCLUSIONS: Strategies to increase confidence, skills, and enjoyment of physical activity may only be effective for promoting activity among later maturing girls.

Patterns of age-related change in physical activity during the transition from elementary to high school.

This study was designed: 1) to describe patterns of age-related change in total and moderate-to-vigorous physical activity (MVPA) in children as they transitioned from elementary school to high school, and 2) to determine if those patterns differed across demographic sub-groups formed on the basis of gender, race/ethnicity, parent education (socioeconomic status), and urbanicity. A cohort of children (analysis sample, N = 951) was comprised of students drawn from two public school districts in South Carolina. Physical activity was measured by accelerometry on at least two and up to five occasions between 2010 and 2017. Growth curve analyses were performed to describe the pattern of age-related change in the physical activity variables for the full sample and for demographic sub-groups. A relatively steep age-related decline in total physical activity was observed in children before age 14, with a slower rate after that age. Physical activity was lower in girls than boys, and the age-related rate of decline was steeper in girls. Physical activity patterns did not differ across race/ethnicity groups, but children of parents with less education were more active than children of parents with more education. Children living in rural areas participated in less MVPA than children living in urban settings, and this difference increased with increasing age. These findings indicate that children experience a particularly steep decrease in physical activity as they transition from elementary to middle school, and this trend is particularly prominent in girls, children living in rural areas, and children of parents with college education.

Pathways of influences leading to adoption of the Faith, Activity and Nutrition (FAN) program in a statewide initiative.

RE-AIM (Reach, effectiveness, Adoption, Implementation, Maintenance) and CFIR (Consolidated Framework for Implementation Research) are complementary frameworks guiding research on dissemination and implementation of evidence-based interventions and factors influencing this process. Faith, Activity, and Nutrition (FAN) is an evidence-based program that increased physical activity and fruit and vegetable intake in faith-based settings. The aims of this adoption study were to quantify state-wide church level adoption rates and congregant reach of FAN in accordance with RE-AIM guidelines, and to explore the association of CFIR-derived constructs of the church inner setting and pastor characteristics with FAN adoption. Church recruitment was documented, and data were collected via telephone-administered surveys from 93 pastors in adopting churches and 60 pastors in non-adopting churches. Qualitative Comparative Analysis (QCA) identified combinations of CFIR-derived church and pastor characteristics sufficient for FAN adoption. As defined by RE-AIM, church-level FAN adoption was 11.7 % and congregant-level reach was 20.0 %. Fourteen pathways to adoption were identified; seven of these featured the presence of a culture of concern for congregant health along with openness to new ideas. Results suggest early assessment of these two CFIR-derived inner setting constructs may help identify faith-based organizations predisposed to undertake a comprehensive, environmental intervention to promote congregant health.

Operationalizing and Testing the Concept of a Physical Activity Desert.

BACKGROUND: The prevalence of childhood obesity is higher in economically and socially deprived areas. Higher levels of physical activity reduce the risk of excessive weight gain in youth, and research has focused on environmental factors associated with children's physical activity, though the term "physical activity desert" has not come into wide use. METHODS: This exploratory study operationalized the term "physical activity desert" and tested the hypothesis that children living in physical activity deserts would be less physically active than children who do not. A cross-sectional study design was applied with 992 fifth-grade students who had provided objectively measured physical activity data. Five of 12 possible elements of the built environment were selected as descriptors of physical activity deserts, including no commercial facilities, no parks, low play spaces, no cohesion, and the presence of incivilities. RESULTS: Univariate and multivariate analyses showed that only the absence of parks was associated with less physical activity in children. CONCLUSION: Children living in a "no park" zone were less active than their counterparts who lived near a park. This study contributes preliminary conceptual and operational definitions of "physical activity desert." Future studies of physical activity deserts should be undertaken in larger and more diverse samples.

Program Implementation and Church Members' Health Behaviors in a Countywide Study of the Faith, Activity, and Nutrition Program.

Implementation research of health programs in faith-based organizations is lacking. The Faith, Activity, and Nutrition (FAN) program helps churches improve physical activity and fruit and vegetable behaviors of members. This study examined associations between implementation of FAN intervention components and church members' physical activity, fruit and vegetable behaviors, and self-efficacy for improving these behaviors. FAN was implemented in 35 churches in a southeastern US county. After attending in-person training, led by community health advisors, church committees received 12 months of telephone-delivered technical assistance to implement FAN according to 4 components: increasing opportunities, increasing guidelines and policies, increasing pastor support, and increasing messages for physical activity and healthy eating in their church. In this correlational study, FAN coordinators (n = 35) for each church reported baseline practices in 2015 and 12-month follow-up implementation of the 4 components for physical activity and healthy eating in 2016. Church members (n = 893) reported perceived implementation, physical activity and fruit and vegetable behaviors, and self-efficacy at 12-month follow-up in 2016. Independent variables were coordinator-reported baseline practices, baseline-adjusted 12-month implementation, and member-perceived 12-month implementation. Multilevel modeling examined associations between independent variables and member-reported 12-month physical activity and fruit and vegetable behaviors and self-efficacy. Coordinator-reported 12-month implementation of fruit and vegetable opportunities was associated with member fruit and vegetable consumption. Member perceptions at 12 months of church physical activity opportunities, pastor support, and messages were associated with higher self-efficacy for physical activity; pastor support and messages were positively associated with physical activity. Member perceptions at 12 months of fruit and vegetable opportunities, pastor support, and messages were associated with higher fruit and vegetable consumption and self-efficacy. Member-perceived implementation was more strongly associated with member behaviors than coordinator-reported implementation. Providing opportunities for healthy eating during already scheduled events may be an effective strategy for improving fruit and vegetable behavior.

Predictors of implementation in the Faith, Activity, and Nutrition dissemination and implementation study: application of the Consolidated Framework for Implementation Research (CFIR) in a statewide initiative.

Faith-based organizations, with broad reach and trust, are well-positioned to promote health. The purpose of the study was to examine 12-month implementation and its predictors in the statewide Faith, Activity, and Nutrition (FAN) dissemination and implementation (D&I) study. Churches (n = 93; 42% predominantly African American) in the [South Carolina] Conference of the United Methodist Church trained by Community Health Advisors participated in the study. Church FAN coordinators (n = 92) completed implementation surveys regarding opportunities, policies, messages, and pastor support for physical activity (PA) and healthy eating (HE) at baseline and 12 months. FAN coordinators and pastors (n = 93) completed CFIR-based measures at baseline, immediate post-training, and 12 months. Repeated measures ANOVAs tested change in PA and HE implementation composite scores; Cohen's d indicated magnitude of change. Mixed model linear regression tested whether CFIR items predicted 12-month implementation, controlling for baseline implementation. PA (d = 1.42) and HE (d = 2.05) implementation increased significantly over time. PA and HE implementation were significantly greater in predominantly African American (versus White) congregations, and HE implementation was greater in churches with <500 members. FAN coordinators' ratings of the inner setting (networks/communication, culture, tension for change, organizational rewards, readiness, and congregant needs) and implementation process (engaging opinion leaders and champions) domains were most predictive of implementation outcomes. Few pastor ratings related to implementation outcomes. This study identified constructs, guided by CFIR, that may be important for understanding PA and HE implementation in churches. Future studies will need to test them for replication. Greater changes in implementation outcomes among African American churches underscores the potential of promoting health equity through this setting.

Associations between three measures of physical activity and selected influences on physical activity in youth transitioning from elementary to middle school.

Measurement of physical activity is challenging, and objective and subjective methods can be used. The purposes of this study were to apply structural equation modeling in: 1) examining the associations between three distinct measures of physical activity and three factors that are often found to be correlated to physical activity in children, and 2) examining the associations of the combination of three measures with the same correlates in a cohort of youth followed from 5th to 7th grade. A total of 409 children (45% boys) had complete physical activity data derived from accelerometers, self-report by youth, and proxy-report by parents. The potential correlates of physical activity included self-efficacy, physical activity support, and facilities for physical activity. Structural equation models were used to assess the relationship between physical activity and the correlates. The structural equation models examining associations between individual measures of physical activity and selected correlates showed that parent-reported and child self-reported physical activity were associated with parental support for physical activity and self-efficacy. Objectively measured physical activity was associated only with facilities for physical activity. A structural equation model showed that a composite expression of physical activity, based on the inclusion of all three individual measures, was associated with all three correlates of physical activity. In conclusion, combining measures of physical activity from different sources may improve the identification of correlates of physical activity. This information could be used to plan more effective physical activity interventions in children and youth.

Implementation Monitoring of a Promotora-Led, Home-Based Obesity Prevention Pilot Study With Latino Preschool Children and Their Mothers.

BACKGROUND: Latino preschool children have higher rates of obesity than children from other racial/ethnic backgrounds. Few effective, culturally-tailored obesity prevention interventions exist that have focused on Latino preschool children, and even fewer have published results of the process evaluation. The purpose of this paper was to monitor reach, fidelity, and completeness of implementation to determine whether ANDALE, a promising promotora-led, home-based pilot study to prevent obesity in Latino preschool children, was implemented as planned. METHODS: Guided by a logic model, we assessed reach, implementation fidelity and completeness through descriptive analyses of multiple data sources. Reach was assessed through attendance records. Fidelity was assessed via observation checklist and completeness was assessed via survey with both parents and promotoras in a subsample of 12 families. RESULTS: Promotoras recruited participants primarily through their own social networks and delivered the intervention to 50 families (mother-child dyads); the majority were of Mexican-origin, low-acculturation, dual-parent households. Nearly all (98%) families completed the whole 10-week intervention. Results demonstrated completeness and fidelity of implementation were acceptable in a subsample of 12 families. In sum, 75% of families in the subsample met the criteria (≥75%) for overall implementation of essential program elements (i.e., reach, completeness, and fidelity). CONCLUSION: Evidence suggests that ANDALE was delivered with high levels of completeness and fidelity in this sample of Latino families with preschool-aged children. These results support implementation of ANDALE in a large, randomized trial.

Healthy Eating and Physical Activity Interventions in Faith-Based Settings: A Systematic Review Using the Reach, Effectiveness/Efficacy, Adoption, Implementation, Maintenance Framework.

CONTEXT: Faith-based health interventions may improve obesity-related health behaviors, including healthy eating and physical activity. However, the generalizability of results and comprehensiveness of reporting for critical design elements sufficient for large-scale implementation and broad public health impact are unclear. This review assesses the degree to which faith-based healthy eating and physical activity programs report intervention elements using the reach, effectiveness/efficacy, adoption, implementation, maintenance framework. EVIDENCE ACQUISITION: A systematic literature search was initiated in June 2017, and updated searches concluded in December 2019. Articles were included if they (1) were published in an English language peer-reviewed journal, (2) were conducted in the U.S., (3) were interventions, (4) included individual-level healthy eating or physical activity behavioral outcomes, (5) were conducted within an organizational setting, and (6) were faith-based. Intervention elements were extracted, and comprehensiveness of reporting for intervention elements was assessed according to reach, effectiveness/efficacy, adoption, implementation, maintenance domains. EVIDENCE SYNTHESIS: A total of 38 interventions (46 articles) met the inclusion criteria. Most were conducted at the individual/interpersonal level (66%); few included additional elements of policy or environmental change (34%). Most interventions showed favorable changes in at least 1 health behavior outcome. No intervention addressed all reach, effectiveness/efficacy, adoption, implementation, maintenance indicators. The mean level of reporting was low for all reach, effectiveness/efficacy, adoption, implementation, maintenance dimensions (reach: 2.3 of 5 [SD=1.0] indicators, efficacy/effectiveness: 2.3 of 4 [SD=0.8] indicators, adoption: 3.7 of 6 [SD=1.4] indicators, implementation: 1.3 of 3 [SD=0.6] indicators, maintenance: 0.3 of 3 [SD=0.5] indicators). CONCLUSIONS: Studies reporting outcomes of faith-based interventions to improve healthy eating/physical activity behaviors lack the information necessary to understand the potential for broad dissemination and implementation in community settings. Future studies should report on the considerations for the translation and dissemination of evidence-based programs to expand public health impact.

Personal, Social, and Environmental Influences on Physical Activity in Groups of Children As Defined by Different Physical Activity Patterns.

BACKGROUND: Interventions promoting physical activity (PA) in youth have had limited success, in part because studies with methodological challenges have yielded an incomplete understanding of personal, social, and environmental influences on PA. This study described changes in these factors for subgroups of youth with initially high PA that decreased (Active-Decline) compared with children with initially low PA that decreased (Inactive-Decline) from fifth to ninth grades. METHODS: Observational, prospective cohort design. Participants (n = 625) were fifth-grade children recruited in 2 school districts and followed from elementary to high school. Students and their parents responded to questionnaires to assess personal, social, and perceived physical environmental factors in the fifth (mean age = 10.5 [.5] y) and ninth (mean age = 14.7 [.6] y) grades. Analyses included a mixed-model 2-way repeated analysis of variances. RESULTS: Children in the Active-Decline compared with those in the Inactive-Decline group showed a more favorable profile in 6 of 8 personal variables (perceived barriers, self-efficacy, self-schema, enjoyment, competence, and fitness motives) and 4 of 6 social variables (friend support, parent encouragement, parent support, and parent-reported support). CONCLUSIONS: The results suggest efforts to promote PA should target selected personal, social, and perceived environmental factors beginning before age 10 and continuing through adolescence.

The Faith, Activity, and Nutrition (FAN) Dissemination and Implementation Study: 24-Month Organizational Maintenance in a Countywide Initiative.

Introduction: Despite the important role that faith-based organizations can play in eliminating health disparities, few studies have focused on organizational change and maintenance of interventions in this setting, making their long-term impact unknown. This study reports 24-month maintenance of the Faith, Activity, and Nutrition (FAN) program in a southeastern county. Previously reported findings of reach, adoption, implementation, and effectiveness are also summarized. Methods: Church coordinators from 35 intervention churches (97% predominantly African American) located in a rural, medically underserved county in South Carolina were interviewed at baseline (2015), and 12- and 24-months post-training regarding implementation of physical activity (PA) and healthy eating (HE) components of the FAN program. Guided by the RE-AIM framework, organizational maintenance was defined as church coordinator-reported 24-month implementation of the four FAN components (providing opportunities, setting guidelines/policies, sharing messages, engaging pastor). Repeated measures analyses (mixed models) examined change in implementation over time. Churches were also classified as maintainers, non-sustained implementers, and low implementers for each FAN component. Statistical analyses were conducted in 2019. Results: Church coordinators reported significantly greater implementation of both PA and HE FAN components at 12 and 24 months compared to baseline (medium to large effects). The percentage of churches classified as maintainers ranged from 21 to 42 and 27 to 94% across PA and HE components, respectively. Most churches (58% for PA, 97% for HE) were maintaining at least one FAN component at 24 months. Conclusions: These promising findings position FAN well for the national implementation study now underway. Trial Registration: This study is registered at www.clinicaltrials.gov NCT02868866.
