Parents' recalled experiences of the child centred health dialogue in children with overweight: a qualitative study.

BACKGROUND: Because overweight and obesity are still increasing and prevention of childhood obesity is more likely to be effective when initiated in preschool children, the Child Health Service in the south of Sweden developed a structured child-centred health dialogue model targeting all 4-year-old children and their families. The aim of this study was to describe parents' recalled experiences of this health dialogue in children with overweight. METHODS: A qualitative inductive approach with purposeful sampling was used. Thirteen individual interviews with parents (including 11 mothers and 3 fathers) were conducted and analysed with qualitative content analysis. RESULTS: The analysis resulted in two categories: 'A valuable visit with a subtle individual impact' that described parents' recalled experiences of the health dialogue and 'There is a complex interaction between weight and lifestyle' that reflected the parents' perceptions of the relationship between their children's weight and lifestyle. CONCLUSIONS: Parents recalled the child-centred health dialogue as important and described discussing a healthy lifestyle as one of the obligations of the Child Health Service. Parents wanted confirmation that their family lifestyle was healthy; however, they did not want to discuss the relationship between their family lifestyle and their children's weight. Parents expressed that when their child followed the child's growth curve, then this indicated healthy growth. This study supports using the child-centred health dialogue as a model to provide structure for discussing a healthy lifestyle and growth but highlights the difficulties of discussing body mass index and overweight, especially in the presence of children.

Qualitative Evaluation of University Students' Experience Delivering an Obesity Prevention Programme in Elementary Schools.

The Coordinated Approach to Child Health (CATCH) programme is an accredited obesity prevention programme in the United States, teaching children about nutrition, physical activity, and screen time limits. This study aimed to evaluate the perceptions of undergraduate and graduate student leaders' about their experience delivering the CATCH programme in elementary schools in Northern Illinois school districts during the 2019-2020 school year and its impact on their personal and professional skills and on programme participants. An email questionnaire was sent to eligible students. Grounded theory was used to analyze the students' responses. Two researchers assigned codes to the data and identified themes. Twenty-one students responded (50% response rate). Six identified themes include "purpose of CATCH programme," "school facilities and resources," "university students experience with CATCH lessons and activities," "benefits to university student," "benefits to children and teachers," and "identified weaknesses and suggested improvements to CATCH." University students delivering the CATCH programme appreciated the opportunity to practice in a real-world setting, gained transferable professional skills, increased programme content knowledge, identified CATCH programme benefits/strengths, and planned to apply lessons learned to future practice.

System approaches to childhood obesity prevention: ground up experience of adaptation and real-world context.

OBJECTIVE: Childhood obesity prevention is critical to reducing the health and economic burden currently experienced by the Australian economy. System science has emerged as an approach to manage the complexity of childhood obesity and the ever-changing risk factors, resources and priorities of government and funders. Anecdotally, our experience suggests that inflexibility of traditional research methods and dense academic terminology created issues with those working in prevention practice. Therefore, this paper provides a refined description of research-specific terminology of scale-up, fidelity, adaptation and context, drawing from community-based system dynamics and our experience in designing, implementing and evaluating non-linear, community-led system approaches to childhood obesity prevention. DESIGN: We acknowledge the importance of using a practice lens, rather than purely a research design lens, and provide a narrative on our experience and perspectives on scale-up, fidelity, context and adaptation through a practice lens. SETTING: Communities. PARTICIPANTS: Practice-based researcher experience and perspectives. RESULTS: Practice-based researchers highlighted the key finding that community should be placed at the centre of the intervention logic. This allowed communities to self-organise with regard to stakeholder involvement, capacity, boundary identification, and co-creation of actions implemented to address childhood obesity will ensure scale-up, fidelity, context and adaptation are embedded. CONCLUSIONS: We need to measure beyond primary anthropometric outcomes and focus on evaluating more about implementation, process and sustainability. We need to learn more from practitioners on the ground and use an implementation science lens to further understand how actions work. This is where solutions to sustained childhood obesity prevention will be found.

Rethinking sustainability in childhood obesity prevention interventions: learning from South Australia's Obesity Prevention and Lifestyle (OPAL) Programme.

Increases in childhood obesity have occurred across a relatively short time-period, yet childhood obesity prevention is a longer-term game. Programmes have only identified population-level changes after 12 years of on-the-ground activity [Romon et al.]. Community stakeholders can impact the success of public health interventions [Ganter et al.; Lee et al.] and they have been identified as a critical success factor for programme sustainability [Schell et al.]. Qualitative research with stakeholders (n = 59) provides their insights and understandings of the sustainability of OPAL, a South Australian childhood obesity prevention programme. Stakeholders identified activities that they thought contributed to improved sustainability of action such as embedding obesity prevention into organizational policy and plans; and installation of infrastructure within communities to modify physical environments. In contrast, there was little appetite for sustaining OPAL or other formulations of a childhood obesity prevention programme. This research has implications for planning and implementation of community-based childhood obesity prevention initiatives when considering the balance of the portfolio of activities for implementation.

Examining correlates of feeding practices among parents of preschoolers.

Background: Parent feeding practices play a critical role in children's eating behaviors. Limited research has explored child-level correlates of parent feeding practices. Aim: To identify correlates of feeding practices (responsive and controlling) among parents of preschoolers US. Methods: Participants included parents (n = 273) of preschoolers (3-5 years), recruited from Early Care and Education settings (n = 24) located in a metropolitan city in the US. Analysis included descriptives, correlations, and multiple regression. Results: For responsive feeding practices, positive associations included child's weight with unintentional modeling (ß = .17, 95% CI [0.12, 0.53]), child vegetable consumption with behavioral role modeling (ß = 0.22, 95% CI [0.17, 0.44]), and parent monitoring with verbal modeling (ß = 0.21, 95% CI [0.12, 0.34]). For controlling feeding practices, parent restriction was positively associated with child weight concern (ß = 0.22, 95% CI [0.13, 0.39]) and parent monitoring (ß = 0.13, 95% CI [0.01, 0.19]), whereas child vegetable consumption was negatively associated (ß = -0.16, 95% CI [-0.27, -0.05]). Pressure to eat was negatively associated with child weight concern (ß = -0.18, 95% CI [-0.45, -0.09]), child fruit consumption (ß = -0.12, 95% CI [-0.37, -0.01]), household income (ß = -0.13, 95% CI [-0.30, -0.02]), and parent weight (ß = -0.14, 95% CI [-0.60, -0.05]), Conclusions: Findings highlight the importance of child characteristics when examining correlates of parent feeding practices, demonstrating bidirectional interactions between parent feeding practices and children's eating behaviors. Considering child-level correlates may improve the implementation of responsive feeding practices and reduce controlling feeding practices.

Process evaluations of early childhood obesity prevention interventions delivered via telephone or text messages: a systematic review.

BACKGROUND: Increasingly, public health interventions are delivered via telephone and/or text messages. Recent systematic reviews of early childhood obesity prevention interventions have not adequately reported on the way interventions are delivered and the experiences/perceptions of stakeholders. We aimed to summarise the literature in early childhood obesity prevention interventions delivered via telephone or text messages for evidence of application of process evaluation primarily to evaluate stakeholders' acceptability of interventions. METHODS: A systematic search of major electronic databases was carried out using the Population, Intervention, Comparison, Outcomes framework. Studies were included if interventions were delivered via telephone/text messages; aimed at changing caregivers' behaviours to prevent early childhood obesity; with one or more outcomes related to early obesity risk factors such as breastfeeding, solid feeding, tummy time, sleep and settling, physical activity and screen time; published from inception to May 2020. All eligible studies were independently assessed by two reviewers using the Cochrane Collaboration tool for assessing risk of bias. Qualitative studies were assessed using the Consolidated Criteria for Reporting Qualitative Research and Standards for Reporting Qualitative Research tools. RESULTS: Twenty-four studies were eligible, and the overall risk of bias was low. Eight studies (33%) had evidence of process evaluation that examined participants' perceptions of interventions. Participants appreciated the convenience of receiving interventions via telephone or text messages. 63% of all studies in this review showed improvement in one or more behaviours related to childhood obesity prevention. Participants were likely to modify behaviours if they received information from a credible source such as from health professionals. CONCLUSION: There is limited reporting of stakeholders' experiences in early obesity prevention studies delivered by telephone or text messages. Only one-third of studies examined participants' acceptability and the potential for delivery of childhood obesity prevention interventions conveniently using this mode of delivery. Interventions delivered remotely via telephone or text messages have the potential to reach equal or a greater number of participants than those delivered via face-to-face methods. Future research should build in process evaluation alongside effectiveness measurements to provide important insight into intervention reach, acceptability and to inform scale up.

Quantifying parent engagement in the randomized Fuel for Fun impact study identified design considerations and BMI relationships.

BACKGROUND: Parent participation in children's health interventions is insufficiently defined and measured. This project quantified parent participation to enable future examination with outcomes in an intervention focused on 4th graders, aged 9-11 years, and their families living in northern Colorado. METHODS: Indices were developed to measure type (Parent Participation Profile; PPP) and intensity (Parent Engagement Intensity; PEI) of engagement in Fuel for Fun (FFF), an asymmetric school-and family-based intervention for 4th graders. Study arm-specific participation opportunities were catalogued and summed to calculate the PPP. An algorithm considered frequency, effort, convenience, and invasiveness of each activity to calculate PEI. Indices were standardized (0-100%) using study arm-specific divisors to address asymmetric engagement opportunities. Parents who completed ≥75% of the PPP were defined as Positive Deviants. Youth height and weight were measured. Youth BMI percentile change was compared with parent Positive Deviant status using general linear modeling with repeated measures that included the participation indices. RESULTS: Of 1435 youth, 777 (54%) had parent participation in at least one activity. Standardized means were 41.5 ± 25.4% for PPP and 27.6 ± 20.9% for PEI. Demographics, behaviors or baseline FFF outcomes did not differ between the Positive Deviant parent (n = 105) and non-Positive Deviant parents (n = 672); but more Positive Deviant parents followed an indulgent feeding style (p = 0.015). Standardized intensity was greater for Positive Deviant parents; 66.9 ± 20.6% vs 21.5 ± 12.7% (p < 0.001) and differences with non-Positive Deviant parents were related to activity type (p ≤0.01 for six of eight activities). Standardized participation intensity was associated with engagement in a greater number of standardized activity types. Among participating parents, standardized intensity and breadth of activity were inversely related to the youth BMI percentile (n = 739; PEI r = -0.39, p < 0.001; PPP r = -0.34, p < 0.001). Parent engagement was not associated with parent BMI change. CONCLUSIONS: An activity-specific intensity schema operationalized measurement of parent engagement in a complex, unbalanced research design and can serve as a template for more sensitive assessment of parent engagement. Positive deviance in parent engagement was not a function of personal, but rather activity characteristics. PPP and PEI increased with fewer requirements and convenient, novel, and personalized activities. Parent engagement indices affirmed lower engagement by parents of overweight/obese youth and concerns about target reach.

Translation of two healthy eating and active living support programs for parents of 2-6 year old children: a parallel partially randomised preference trial protocol (the 'time for healthy habits' trial).

BACKGROUND: Parents are key decision makers and role models in establishing and maintaining healthy behaviours in their children. Interventions involving parents have been shown to be more effective than those that do not, but there are barriers to participation. Efficacy trials have previously been conducted on two such parent-focussed healthy eating and active living interventions with the potential to overcome these barriers - Healthy Habits (telephone-based) and Time2bHealthy (online) with promising results. Further research is now required to determine the effectiveness of these interventions in a real-world context. The Time for Healthy Habits study is a 3-arm partially randomised preference trial which aims to evaluate the effectiveness and cost-effectiveness of two theory-based programs to promote healthy eating and appropriate levels of movement behaviours (physical activity, sedentary behaviour and sleep) for parents of 2- to 6-year-old children (Healthy Habits Plus telephone-based program and Time2bHealthy online program), when compared to a comparison group receiving written materials. METHODS: Participants will be recruited across five Local Health Districts in New South Wales, Australia. The partially randomised preference design initially allows for participants to decide if they wish to be randomised or opt to select their preferred intervention and has been recommended for use to test effectiveness in a real-world setting. Both interventions incorporate multiple behaviour change techniques and support parents to improve their children's healthy eating, and movement behaviours (physical activity, sedentary behaviour and sleep) and run for 12 weeks, followed by a 3-month and 9-month post-baseline follow-up. Participants will also be asked to complete a process evaluation questionnaire at the completion of the intervention (3-months post-baseline). Outcomes include fruit and vegetable intake (primary outcome), non-core food intake, weight status, physical activity, sedentary behaviour, and sleep habits. DISCUSSION: To our knowledge, this is the first translational research trial evaluating the effectiveness and cost-effectiveness of a healthy eating and active living intervention in the 2- to 6-years age group. The results will build the evidence base in regard to translation of effective childhood obesity prevention interventions and inform the implementation and delivery of community based childhood obesity prevention programs.

Club Fit: Development of a Physical Activity and Healthy Eating Intervention at a Boys & Girls Club After School Program.

Children and adolescents from minority and low income backgrounds face social and environmental challenges to engaging in physical activity and healthy eating to maintain a healthy weight. In this study, we present pilot work to develop and implement a multi-component physical activity and healthy eating intervention at a Boys & Girls Club (BGC) afterschool program. Using a community-based participatory approach, BGC staff and academic researchers developed intervention components informed by formative studies and based on a Social Ecological Theory framework. Components included healthy eating and physical activity policy implementation, staff training, a challenge and self-monitoring program for healthy behaviors, a peer-coaching program for healthy behaviors, and a social marketing campaign. We assessed pilot feasibility through a single group, pre-post study design with measures collected at baseline and 6 months. The sample included 61 children with a mean age of 10.4 years. Mean (SD) body mass index (BMI) percentile was 72.8 (28.9); 47.5% were in the healthy weight range for their age. We found statistically significant improvements of self-efficacy and motivation for physical activity. Self-efficacy and motivation for fruit and vegetable consumption, sugary beverage consumption, and screen time improved but were not statistically different from baseline. We found no improvements of perceived social support, objectively measured physical activity, or self-reported dietary quality. Though BMI did not improve overall, a dose effect was observed such that attendance in Club Fit specific programming was significantly correlated with decreased BMI z scores. Processes and products from this study may be helpful to other communities aiming to address childhood obesity prevention through afterschool programs.

The perception of school food-service professionals on the implementation of the Healthy, Hunger-Free Kids Act of 2010: a mixed-methods study.

OBJECTIVE: To: (i) understand the nutrition attitudes, self-efficacy, knowledge and practices of school food-service personnel (SFP) in Nebraska and (ii) identify potential barriers that schools face in offering healthy school meals that meet the US Department of Agriculture (USDA) nutrition standards. DESIGN: Convergent parallel mixed-methods study. SETTING: Kindergarten-12th grade schools in Nebraska, USA.ParticipantsSFP (260 survey participants; fifteen focus group participants) working at schools that participate in the USDA National School Lunch Program. RESULTS: Mixed-methods themes identified include: (i) 'Mixed attitudes towards healthy meals', which captured a variety of conflicting positive and negative attitudes depending on the situation; (ii) 'Positive practices to promote healthy meals', which captured offering, serving and promotion practices; (iii) 'Mixed nutrition-related knowledge', which captured the variations in knowledge depending on the nutrition concept; and (iv) 'Complex barriers', which captured challenges with time, support and communication. CONCLUSIONS: The study produced relevant findings to address the barriers identified by SFP. Implementing multicomponent interventions and providing training to SFP may help reduce some of the identified barriers of SFP.

The impact of HENRY on parenting and family lifestyle: Exploratory analysis of the mechanisms for change.

BACKGROUND: Childhood obesity is a major public health concern. In the United Kingdom, a quarter of children are overweight or obese at age 5 years. Overweight and obese children are more likely to develop serious health issues such as diabetes later in life. Consequently, there is an urgent need for effective, early obesity prevention and intervention. This study investigated the impact of an 8-week child obesity intervention-HENRY (Health Exercise Nutrition for the Really Young)-designed to help parents with preschool children develop the skills and knowledge needed to improve family lifestyle and well-being. We were particularly interested in exploring the potential mechanisms by which HENRY may have a positive impact. METHOD: Focus groups (n = 7, total participants = 39) were completed with mothers attending the HENRY programme at one of seven locations across England. They took place within 2 weeks of programme completion. Follow-up telephone interviews were completed with a subsample of participants (n = 10) between 17 and 21 weeks later. RESULTS: Parents consistently reported enhanced self-efficacy in terms of improved confidence in their ability to encourage healthier behaviours such as eating fruit and vegetables and increasing physical activity, and improvements to family health behaviours. Many changes were reportedly sustained at follow-up. Data provided insights into the potential mechanisms that created the conditions for the positive changes. Participants described the importance of mutual support, being listened to by facilitators, and encouragement to identify their own ideas. Their comments indicated the success of a solution-focused, strength-based, partnership approach to supporting family lifestyle change. CONCLUSION: The results of this study contribute to the body of evidence suggesting that HENRY may have a positive impact on parenting and family lifestyle behaviour. Although data were collected in 2011, the findings contribute to an understanding of the components of effective obesity prevention in young children.

Development and testing of a novel survey to assess Stakeholder-driven Community Diffusion of childhood obesity prevention efforts.

BACKGROUND: Involving groups of community stakeholders (e.g., steering committees) to lead community-wide health interventions appears to support multiple outcomes ranging from policy and systems change to individual biology. While numerous tools are available to measure stakeholder characteristics, many lack detail on reliability and validity, are not context specific, and may not be sensitive enough to capture change over time. This study describes the development and reliability of a novel survey to measure Stakeholder-driven Community Diffusion via assessment of stakeholders' social networks, knowledge, and engagement about childhood obesity prevention. METHODS: This study was completed in three phases. Phase 1 included conceptualization and online survey development through literature reviews and expert input. Phase 2 included a retrospective study with stakeholders from two completed whole-of-community interventions. Between May-October 2015, 21 stakeholders from the Shape Up Somerville and Romp & Chomp interventions recalled their social networks, knowledge, and engagement pre-post intervention. We also assessed one-week test-retest reliability of knowledge and engagement survey modules among Shape Up Somerville respondents. Phase 3 included survey modifications and a second prospective reliability assessment. Test-retest reliability was assessed in May 2016 among 13 stakeholders involved in ongoing interventions in Victoria, Australia. RESULTS: In Phase 1, we developed a survey with 7, 20 and 50 items for the social networks, knowledge, and engagement survey modules, respectively. In the Phase 2 retrospective study, Shape Up Somerville and Romp & Chomp networks included 99 and 54 individuals. Pre-post Shape Up Somerville and Romp & Chomp mean knowledge scores increased by 3.5 points (95% CI: 0.35-6.72) and (- 0.42-7.42). Engagement scores did not change significantly (Shape Up Somerville: 1.1 points (- 0.55-2.73); Romp & Chomp: 0.7 points (- 0.43-1.73)). Intraclass correlation coefficients (ICCs) for knowledge and engagement were 0.88 (0.67-0.97) and 0.97 (0.89-0.99). In Phase 3, the modified knowledge and engagement survey modules included 18 and 25 items, respectively. Knowledge and engagement ICCs were 0.84 (0.62-0.95) and 0.58 (0.23-0.86). CONCLUSIONS: The survey measures upstream stakeholder properties-social networks, knowledge, and engagement-with good test-retest reliability. Future research related to Stakeholder-driven Community Diffusion should focus on prospective change and survey validation for intervention effectiveness.

A formative study to understand perspectives of families eligible for a pediatric obesity program: a qualitative study.

BACKGROUND: Raising Well® (RW) was initiated in 2015 by Envolve PeopleCare™ at the request of health plans seeking a solution to work with families on Medicaid that have a child with overweight or obesity. RW uses expert clinical coaches via phone contact to deliver an educational intervention promoting lifestyle change to families with at least one overweight or obese child in an eligible Medicaid health plan. This gives RW significant potential for reach and population impact. This project aimed to understand how to maximize this impact by exploring perspectives of RW, using a conceptual framework informed by the Conceptual Model of Implementation Research, including assessment of the feasibility, acceptability, and appropriateness of RW; determining satisfaction among those experiencing coaching; identifying reasons individuals do not participate; and developing recommendations to enhance interest and participation. METHODS: Semi-structured interviews were conducted with 70 RW-eligible families across four states, who were described as: active participants, respondents who dropped or stopped RW, and RW non-participants. Following the interviews, the transcripts were coded inductively and deductively using a grounded theory approach, considering themes from the conceptual framework; themes also emerged from the data. RESULTS: From this sample, 19 families reported to be active coaching participants, 24 had dropped coaching, and 27 were RW non-participants. A number of themes were identified. Feasibility themes included coaches' flexibility and willingness to work with the family's schedule. Acceptability themes suggest providing actionable strategies tailored to the family's context and needs, beyond just nutrition information and tips, early in the coaching relationship so the family perceives a benefit for continued participation. With regard to appropriateness, families were also interested in other methods of communication including email, texting, and in person visits. Access to resources for activity and healthy eating in their local community was also recommended. CONCLUSIONS: RW has the potential to improve health and promote wellness. To enhance the impact of this program, RW could incorporate these findings to promote feasibility, acceptability, and appropriateness and improve program implementation. Strategies may include modifying the information provided or the mode of delivering the information.

A cluster randomised controlled trial evaluating the effectiveness and cost-effectiveness of the daily mile on childhood obesity and wellbeing; the Birmingham daily mile protocol.

BACKGROUND: Childhood obesity prevention is a public health priority. Children spend a large proportion of their waking time in school; therefore this is an appropriate setting to implement obesity prevention initiatives. Anecdotal reports suggest that implementing The Daily Mile in schools has had positive effects on childhood obesity, academic attainment and wellbeing. This trial aims to measure the effectiveness of The Daily Mile for improving health and wellbeing. METHODS: This protocol describes a cluster randomised controlled trial (RCT) in 40 primary schools located in Birmingham, UK. Eligible participants are children in years 3 (aged 7-8) and 5 (aged 9-10). The study compares The Daily Mile (intervention) to usual practice (control) in relation to health and wellbeing. The Daily Mile intervention involves an additional 15 min of running or walking integrated into the school day, throughout a 12 month study period. The primary clinical outcome is body mass index (BMI) z-scores at 12 months following introduction of the intervention. The cost per Quality Adjusted Life Year (QALY) is the primary outcome of the economic evaluation. Secondary outcomes include wellbeing, physical fitness and teacher reported academic attainment. DISCUSSION: This study is the first RCT investigating the clinical and cost-effectiveness of The Daily Mile. A range of outcomes will be measured to evaluate the broader wellbeing and academic benefits in addition to clinical outcomes typically measured in childhood obesity prevention trials. The intervention is simple and low-cost, therefore if the benefits are demonstrated it has enormous potential to influence future policy. TRIAL REGISTRATION: ISRCTN: 12698269 .

Methods and design of a 10-week multi-component family meals intervention: a two group quasi-experimental effectiveness trial.

BACKGROUND: Given the ongoing childhood obesity public health crisis and potential protective effect of family meals, there is need for additional family meals research, specifically experimental studies with expanded health outcomes that focus on the at-risk populations in highest need of intervention. Future research, specifically intervention work, would also benefit from an expansion of the target age range to include younger children, who are laying the foundation of their eating patterns and capable of participating in family meal preparations. The purpose of this paper is to address this research gap by presenting the objectives and research methods of a 10-week multi-component family meals intervention study aimed at eliciting positive changes in child diet and weight status. METHODS: This will be a group quasi-experimental trial with staggered cohort design. Data will be collected via direct measure and questionnaires at baseline, intervention completion (or waiting period for controls), and 10-weeks post-intervention. Setting will be faith-based community center. Participants will be 60 underserved families with at least 1, 4-10 year old child will be recruited and enrolled in the intervention (n = 30) or waitlist control group (n = 30). The intervention (Simple Suppers) is a 10-week family meals program designed for underserved families from racial/ethnic diverse backgrounds. The 10, 90-min program lessons will be delivered weekly over the dinner hour. Session components include: a) interactive group discussion of strategies to overcome family meal barriers, plus weekly goal setting for caregivers; b) engagement in age-appropriate food preparation activities for children; and c) group family meal for caregivers and children. Main outcome measures are change in: child diet quality; child standardized body mass index; and frequency of family meals. Regression models will be used to compare response variables results of intervention to control group, controlling for confounders. Analyses will account for clustering by family and cohort. Significance will be set at p < 0.05. DISCUSSION: This is the first experimentally designed family meals intervention that targets underserved families with elementary school age children and includes an examination of health outcomes beyond weight status. Results will provide researchers and practitioners with insight on evidence-based programming to aid in childhood obesity prevention. TRIAL REGISTRATION: NCT02923050 . Registered 03 October 2016.

Big hearts, small hands: a focus group study exploring parental food portion behaviours.

BACKGROUND: The development of healthy food portion sizes among families is deemed critical to childhood weight management; yet little is known about the interacting factors influencing parents' portion control behaviours. This study aimed to use two synergistic theoretical models of behaviour: the COM-B model (Capability, Opportunity, Motivation - Behaviour) and Theoretical Domains Framework (TDF) to identify a broad spectrum of theoretically derived influences on parents' portion control behaviours including examination of affective and habitual influences often excluded from prevailing theories of behaviour change. METHODS: Six focus groups exploring family weight management comprised of one with caseworkers (n = 4), four with parents of overweight children (n = 14) and one with parents of healthy weight children (n = 8). A thematic analysis was performed across the dataset where the TDF/COM-B were used as coding frameworks. RESULTS: To achieve the target behaviour, the behavioural analysis revealed the need for eliciting change in all three COM-B domains and nine associated TDF domains. Findings suggest parents' internal processes such as their emotional responses, habits and beliefs, along with social influences from partners and grandparents, and environmental influences relating to items such as household objects, interact to influence portion size behaviours within the home environment. CONCLUSION: This is the first study underpinned by COM-B/TDF frameworks applied to childhood weight management and provides new targets for intervention development and the opportunity for future research to explore the mediating and moderating effects of these variables on one another.

Testing an Integrated Model of Program Implementation: the Food, Health & Choices School-Based Childhood Obesity Prevention Intervention Process Evaluation.

Childhood obesity is a complex, worldwide problem. Significant resources are invested in its prevention, and high-quality evaluations of these efforts are important. Conducting trials in school settings is complicated, making process evaluations useful for explaining results. Intervention fidelity has been demonstrated to influence outcomes, but others have suggested that other aspects of implementation, including participant responsiveness, should be examined more systematically. During Food, Health & Choices (FHC), a school-based childhood obesity prevention trial designed to test a curriculum and wellness policy taught by trained FHC instructors to fifth grade students in 20 schools during 2012-2013, we assessed relationships among facilitator behaviors (i.e., fidelity and teacher interest); participant behaviors (i.e., student satisfaction and recall); and program outcomes (i.e., energy balance-related behaviors) using hierarchical linear models, controlling for student, class, and school characteristics. We found positive relationships between student satisfaction and recall and program outcomes, but not fidelity and program outcomes. We also found relationships between teacher interest and fidelity when teachers participated in implementation. Finally, we found a significant interaction between fidelity and satisfaction on behavioral outcomes. These findings suggest that individual students in the same class responded differently to the same intervention. They also suggest the importance of teacher buy-in for successful intervention implementation. Future studies should examine how facilitator and participant behaviors together are related to both outcomes and implementation. Assessing multiple aspects of implementation using models that account for contextual influences on behavioral outcomes is an important step forward for prevention intervention process evaluations.

Camp NERF: methods of a theory-based nutrition education recreation and fitness program aimed at preventing unhealthy weight gain in underserved elementary children during summer months.

BACKGROUND: The number of obese children in the US remains high, which is problematic due to the mental, physical, and academic effects of obesity on child health. Data indicate that school-age children, particularly underserved children, experience unhealthy gains in BMI at a rate nearly twice as fast during the summer months. Few efforts have been directed at implementing evidence-based programming to prevent excess weight gain during the summer recess. METHODS: Camp NERF is an 8-week, multi-component (nutrition, physical activity, and mental health), theory-based program for underserved school-age children in grades Kindergarten - 5th coupled with the USDA Summer Food Service Program. Twelve eligible elementary school sites will be randomized to one of the three programming groups: 1) Active Control (non-nutrition, physical activity, or mental health); 2) Standard Care (nutrition and physical activity); or 3) Enhanced Care (nutrition, physical activity, and mental health) programming. Anthropometric, behavioral, and psychosocial data will be collected from child-caregiver dyads pre- and post-intervention. Site-specific characteristics and process evaluation measures will also be collected. DISCUSSION: This is the first, evidence-based intervention to address the issue of weight gain during the summer months among underserved, school-aged children. Results from this study will provide researchers, practitioners, and public health professionals with insight on evidence-based programming to aid in childhood obesity prevention during this particular window of risk. TRIAL REGISTRATION: NCT02908230/09-19-2016.

Parents Working Together: development and feasibility trial of a workplace-based program for parents that incorporates general parenting and health behaviour messages.

BACKGROUND: Parenting programs integrating general parenting and health behaviour messaging may be an effective childhood obesity prevention strategy. The current study explored workplaces as an alternate setting to deliver parenting programs. METHODS: This study involved two phases. The objective of the first phase was to explore interest in and preferred delivery mode of a workplace program that addresses general parenting and health behaviours. The objective of the second phase was to adapt and test the feasibility and acceptability of a pre-existing program that has been successfully run in community settings for parents in their workplace. To achieve the first objective, we conducted 9 individual or small group qualitative interviews with 11 workplace representatives involved in employee wellness/wellness programming from 8 different organizations across Southwestern Ontario. To achieve the second objective, we adapted a pre-existing program incorporating workplace representatives' suggestions to create Parents Working Together (PWT). We then tested the program using a pre/post uncontrolled feasibility trial with 9 employees of a large manufacturing company located in Guelph, Ontario. RESULTS: Results from the qualitative phase showed that a workplace parenting program that addresses general parenting and health behaviour messages is of interest to workplaces. Results from the feasibility trial suggest that PWT is feasible and well received by participants; attendance rates were high with 89 % of the participants attending 5 or more sessions and 44 % attending all 7 sessions offered. All participants stated they would recommend the program to co-workers. Just over half of our parent participants were male (55.6 %), which is a unique finding as the majority of existing parenting programs engage primarily mothers. Impact evaluation results suggest that changes in children's and parents' weight-related behaviours, as well as parents' reports of family interfering with work were in the desired direction post-intervention; however, confidence intervals substantially overlapped zero. Contrary to expectations, parents also reported an increase in restrictive feeding practices. CONCLUSION: Our results indicate that a workplace-based program that addresses general parenting skills and weight-related behaviours may be a feasible way to engage and educate parents, including fathers. A full-scale trial is needed to examine the effectiveness of this approach.

Community Stakeholders' Perceptions of Major Factors Influencing Childhood Obesity, the Feasibility of Programs Addressing Childhood Obesity, and Persisting Gaps.

Prior research has identified numerous factors contributing to increased rates of childhood obesity. However, few studies have focused explicitly on the experience of community stakeholders in low-income communities. This study sought to capture the perspectives of these on-the-ground experts regarding major factors contributing to childhood obesity as well as gaps in current prevention and control efforts. We conducted semi-structured interviews with 39 stakeholders from different community sectors (e.g., healthcare providers, childcare providers, teachers). Data were drawn from the Massachusetts Childhood Obesity Research Demonstration project, a multi-level, multi-sector intervention designed to reduce childhood obesity being implemented in two low-income communities in Massachusetts. Interviews were conducted at baseline, transcribed, coded using grounded theory approach, and analyzed in NVivo 10.0. The vast majority of stakeholders had recently participated in obesity prevention strategies, and nearly all of them identified gaps in prevention efforts either within their organizations or in the broader community. In addition to factors previously identified in the literature, several themes emerged including the need to change policies to increase physical activity during school, offer healthier snacks in schools and afterschool programs, and increase communication and collaboration within the community in prevention efforts. Community stakeholders can impact the success of interventions by bridging the gap between science and lived experience. The results of this study can guide future research by highlighting the importance of including stakeholders' frontline experiences with target populations, and using information on identified gaps to augment intervention planning efforts.
