Evolution of a Coalition Network during a Whole-of-Community Intervention to Prevent Early Childhood Obesity.

Background: Community coalitions often lead and coordinate "whole-of-community" childhood obesity prevention interventions. A growing body of work suggests that coalition network ties, which facilitate transmission of information and advocacy, may be a key part of how such leadership operates. This study provides an understanding of the structure of coalition networks and how this structure changes over time. Methods: We administered semiannual network surveys during a pilot whole-of-community intervention in Somerville, MA (2015-2017). Participants included 16 multisector coalition members and their nominated discussion partners ("first-degree alters") related to childhood obesity prevention. Coalition and first-degree alter respondents named up to 20 discussion partners and reported ties' interaction frequency and perceived influence. Networks were assessed with visualization, descriptive analysis, and exponential random graph models. Results: Total network included 558 stakeholders representing community-based organizations, parents, health care, childcare, universities, among others. Size and membership varied over time. We observed the largest network (n = 256) during intervention planning, and the largest proportion of stakeholders communicating frequently (daily/weekly) about childhood obesity prevention during the peak intervention period. Networks were sparsely interconnected (1%-3% of possible ties observed) and most and least centralized at baseline and follow-up, respectively. Over time, ties were increasingly perceived as influential and siloed within community groups. Conclusions: The network's extensive evolving membership may indicate access to a wide range of resources, ideas, and an ability to broadly disseminate intervention messages. The attenuating network hierarchy over time may have supported more equal participation and control over intervention efforts. Future research should assess generalizability of network patterns, network influences on implementation processes, and possible network interventions.

Community-based sugar-sweetened beverage intervention associated with short-term improvements in self-rated oral health.

To assess the efficacy of a community-based childhood obesity prevention intervention targeting Sugar-sweetened beverage (SSB) consumption on self-rated oral health among children and their parents/caregivers. This study is a secondary analysis of data from a pilot site-randomized intervention (H2 GO!) targeting SSB consumption and obesity risk among children. The 6-week SSB behavioural intervention was implemented in two Massachusetts Boys and Girls Club sites that were matched for size and racial/ethnic composition. Children ages 9-12years and their parents/caregivers were eligible to participate. Data on self-rated oral health and sociodemographics were obtained via self-report surveys at baseline, 2 and 6months. Generalized linear mixed regression models were used to estimate 2- and 6-month change in oral health associated with the intervention. Data are from 100 child participants (46% female; 38% Black, 20% Hispanic, 13% White, 12% Multiracial, 11% Asian) and 87 parent participants (78.2% female; 37.9% Hispanic, 29.9% Black, 14.9% Asian, 10.3% White). At baseline, 47% of child participants rated their oral health as good, followed by very good (32%), fair (11%) and excellent (10%). Among parents, 46.3% rated their oral health as good, followed by very good (29.3%), excellent (9.8%), fair (9.7%) and poor (4.9%). The intervention was associated with 2- and 6-month improvements in child participants' mean self-rated oral health scores (β=0.78; 95% CI: 0.48, 1.087; P<.001; β=0.98; 95% CI: 0.61, 1.34; P<.001, respectively) and with 2-month improvements in parent participants' mean self-rated oral health (β=0.42; 95% CI: 0.016, 0.82; P=.042). Short-term improvements in oral health among children and their parents/caregivers were observed among those participating in a SSB behavioural intervention. Community-based behavioural programmes targeting SSB consumption may be a promising approach to promote oral health as well as prevent childhood obesity.

Exploring healthcare professionals' views of the acceptability of delivering interventions to promote healthy infant feeding practices within primary care: a qualitative interview study.

Early-life nutrition plays a key role in establishing healthy lifestyles and preventing chronic disease. This study aimed to (1) explore healthcare professionals' (HCP) opinions on the acceptability of and factors influencing the delivery of interventions to promote healthy infant feeding behaviours within primary care and (2) identify proposed barriers/enablers to delivering such interventions during vaccination visits, to inform the development of a childhood obesity prevention intervention. A qualitative study design was employed using semi-structured telephone interviews. Data were analysed using qualitative content analysis; findings were also mapped to the Theoretical Framework of Acceptability (TFA). Primary care in Ireland. Twenty-one primary care-based HCP: five practice nurses, seven general practitioners, three public health nurses, three community dietitians and three community medical officers. The acceptability of delivering interventions to promote healthy infant feeding within primary care is influenced by the availability of resources, HCP's roles and priorities, and factors relating to communication and relationships between HCP and parents. Proposed barriers and enablers to delivering interventions within vaccination visits include time constraints v. opportunistic access, existing relationships and trust between parents and practice nurses, and potential communication issues. Barriers/enablers mapped to TFA constructs of Affective Attitude, Perceived Effectiveness and Self-Efficacy. This study provides a valuable insight into HCP perspectives of delivering prevention-focused infant feeding interventions within primary care settings. While promising, factors such as coordination and clarity of HCP roles and resource allocation need to be addressed to ensure acceptability of interventions to HCP involved in delivery.

Opportunities for Impact: Health Promotion in Rural Early Care and Education Environments

Early care and education settings are essential partners in the battle against childhood obesity. We describe an Extension-facilitated early childhood obesity prevention intervention conducted in 25 rural early care and education settings. A total of 148 policy, systems, or environmental changes were achieved, reaching approximately 450 young children. Systems changes were the most prevalent outcome achieved. The experiences of Extension professionals in promoting policy, systems, and environmental changes are highlighted as are implications for other Extension systems and professionals promoting policy, systems, or environmental changes in early care and education settings.

Child Obesity Prevention Intervention in Kuwaiti Summer Camps Targeting Health Behaviors in Nutrition, Physical Activity, and Screen Time

Objective: To assess the effectiveness of an eight-week nutrition and physical activity intervention, entitled: “My Healthy Habits”, at summer camps to prevent obesity, reduce screen time, promote healthy eating habits and physical activity among children. Material and Methods: Eight-week pretest-posttest: intervention versus a comparison group was conducted, in two comparable summer camps in Kuwait and randomized at the site level. Convenient sampling (n=79) included children aged 6-10, receiving 8 weeks of nutrition education: 2 days/week, 40 minutes/day and physical activity sessions: 4 days/week for 20 minutes/day. Outcomes included: the Modified Healthy Habits Survey (items about diet, physical activity and sedentary behavior) and anthropomorphic: Body mass index (BMI) for age and gender percentile and waist-to-height ratio (WHtR). Group changes were measured by independent t-test, and within group changes by the McNemar’s test (categorical data) and paired t-test (interval data). Results: Significant increases in nutrition knowledge scores (from 4.3±1.7 to 10.5±1.2) and in the total score of the major food groups (from 10.0±2.6 to 13.7±2.2) were observed from pretest to posttest. Healthy eating significantly increased (from 12.8±1.8 to 14.5±1.5) for the intervention group only; however, intake of French fries, chips (FF) and sugarsweetened beverages (SSB) remained the same for both groups. Physical activity increased and screen time decreased,only in the intervention group. The participants’ BMI and WHtR decreased significantly in the intervention group: p-value=0.001. Conclusion: Healthy food and physical activity increased, while screen time decreased. Consumption of unhealthy food (FF and SSB) remains an issue.

Applying the Behavior Change Technique Taxonomy to Four Multicomponent Childhood Obesity Interventions.

Applying the Behavior Change Technique Taxonomy has the potential to facilitate identification of effective childhood obesity intervention components. This article evaluates the feasibility of coding Childhood Obesity Prevention and Treatment Consortium interventions and compares reliability between external taxonomy-familiar coders and internal intervention-familiar coders. After training, coder pairs independently coded prespecified portions of intervention materials. An adjudication process was used to explore coding discrepancies. Reliability between internal and external coders was moderate (prevalence and bias-adjusted kappa .38 to .55). Reliability for specific target behaviors varied with substantial agreement for physical activity (.63 to .76) and moderate for dietary intake (.44 to .63). Applying the taxonomy to these interventions was feasible, but agreement was modest. Coding discrepancies highlight the importance of refining coding to capture the complexities of childhood obesity interventions, which often engage multiple recipients (e.g., parents and/or children) and address multiple behaviors (e.g., diet, physical activity, screen time).

Prenatal and Pediatric Primary Care-Based Child Obesity Prevention Program: A Randomized Trial.

To determine impact of a primary care-based child obesity prevention intervention beginning during pregnancy on early childhood weight outcomes in low-income Hispanic families. A randomized controlled trial comparing mother-infant pairs receiving either standard care or the Starting Early Program providing prenatal and postpartum nutrition counseling and nutrition parenting support groups targeting key obesity-related feeding practices in low-income groups. Primary outcomes were reduction in weight-for-age z-scores (WFAzs) from clinical anthropometric measures, obesity prevalence (weight for age ≥95th percentile), and excess weight gain (WFAz trajectory) from birth to age 3 years. Secondary outcomes included dose effects. Pregnant women (n = 566) were enrolled in the third trimester; 533 randomized to intervention (n = 266) or control (n = 267). Also, 358 children had their weight measured at age 2 years; 285 children had weight measured at age 3 years. Intervention infants had lower mean WFAz at 18 months (0.49 vs 0.73, P = .04) and 2 years (0.56 vs 0.81, P = .03) but not at 3 years (0.63 vs 0.59, P = .76). No group differences in obesity prevalence were found. When generalized estimating equations were used, significant average treatment effects were detected between 10-26 months (B = -0.19, P = .047), although not through age 3 years. In within group dose analyses at 3 years, obesity rates (26.4%, 22.5%, 8.0%, P = .02) decreased as attendance increased with low, medium, and high attendance. Mean WFAz and growth trajectories were lower for the intervention group through age 2 years, but there were no group differences at age 3. Further study is needed to enhance sustainability of effects beyond age 2.

Childhood Obesity Evidence Base Project: A Rationale for Taxonomic versus Conventional Meta-Analysis.

Introduction: There is a great need for analytic techniques that allow for the synthesis of learning across seemingly idiosyncratic interventions. Objectives: The primary objective of this paper is to introduce taxonomic meta-analysis and explain how it is different from conventional meta-analysis. Results: Conventional meta-analysis has previously been used to examine the effectiveness of childhood obesity prevention interventions. However, these tend to examine narrowly defined sections of obesity prevention initiatives, and as such, do not allow the field to draw conclusions across settings, participants, or subjects. Compared with conventional meta-analysis, taxonomic meta-analysis widens the aperture of what can be examined to synthesize evidence across interventions with diverse topics, goals, research designs, and settings. A component approach is employed to examine interventions at the level of their essential features or activities to identify the concrete aspects of interventions that are used (intervention components), characteristics of the intended populations (target population or intended recipient characteristics), and facets of the environments in which they operate (contextual elements), and the relationship of these components to effect size. In addition, compared with conventional meta-analysis methods, taxonomic meta-analyses can include the results of natural experiments, policy initiatives, program implementation efforts and highly controlled experiments (as examples) regardless of the design of the report being analyzed as long as the intended outcome is the same. It also characterizes the domain of interventions that have been studied. Conclusion: Taxonomic meta-analysis can be a powerful tool for summarizing the evidence that exists and for generating hypotheses that are worthy of more rigorous testing.

Healthy Habits, Happy Homes Scotland (4HS) feasibility study: Translation of a home-based early childhood obesity prevention intervention evaluated using RE-AIM framework

ObjectiveHealthy Habits, Happy Homes (4H) is a home-based, pre-school childhood obesity prevention intervention which demonstrated efficacy in North America which we translated to Scotland (4HS) by considering contextual factors and adapting study design. RE-AIM Framework was used to assess 1) extent to which development of 4HS intervention (including recruitment) was participatory and inclusive; 2) feasibility of translating a complex public health intervention from one setting to another; 3) extent to which translation was pragmatic and 4) fidelity of intervention to the principles of Motivational Interviewing (MI). Study designFeasibility testing, process evaluation and measurements of intervention fidelity were undertaken to evaluate the translation of 4H to an economically deprived area of Scotland (4HS). Methods4HS study processes; participatory approach, recruitment methods, level of pragmatism were evaluated using the RE-AIM framework. Qualitative and quantitative measures identified key implementation features and functioning of 4HS intervention. Fidelity MI principles was determined through coding of audiotapes using Motivation Interviewing Treatment Integrity (MITI) code. ResultsKey facilitators for positive impact with families, included: inclusive recruitment methods, appropriate channels of communication and correspondence (Reach) with n ​= ​126 enquiries and n ​= ​26 (21%) families recruited. Positive links with local parents and community workers integral to the research process at n ​= ​9 meetings (Effectiveness). 61.5% of families lived in the most deprived data zone in Scotland, 23% were one parent families, thus awareness and consideration of local contextual factors (Adoption) and locally relevant materials were important. 4HS was feasible to deliver, pragmatic in nature and intervention demonstrated good fidelity to MI (Implementation). ConclusionTranslation of 4H from North America to Scotland was successful. Future studies should consider implementation of 4HS approach within routine practice within the UK (practice based evidence) or through thoughtful evaluation in a future trial (evidence based practice).

Influence of pre-schooler and parent nutrition education on carotenoid levels of Mexican-heritage children.

To determine the mediating effect of direct preschool and parent nutrition education on changes in skin carotenoids scores over 2 years in children of Mexican heritage. In a quasi-experimental, community-based study, two school districts were randomly assigned to either a comparison group (parent workshops unrelated to nutrition) or a childhood obesity prevention intervention group which included nutrition education at family nights for parents and at school for children. Changes in skin carotenoid intensity scores (diffCAROT, year 2015 minus 2013) were measured in children as a proxy for fruit and vegetable consumption using Resonance Raman Spectroscopy. Two rural, low-income, school districts from a county in California's Central Valley. 316 Mexican heritage families with children aged 3-8 years. Intervention group children improved over 2 years in skin carotenoid scores relative to comparison group children (diffCAROT mean +1419 (sd 9540) v. -3473 (sd 9272), P = 0·0001). Parent attendance at nutrition education classes partially mediated the intervention effect on diffCAROT (P = 0·02). Controlling for child's age and other covariates, participation in preschool during the study had a significant positive effect on diffCAROT among intervention children compared with controls (P < 0·03), whereas no significant difference by group was observed among those not enrolled in preschool or already enrolled in elementary school. Programmes that combine direct parent and preschool nutrition education may be effective in low-income Mexican heritage families to improve children's intake of fruit and vegetables.

Understanding, comparing and learning from the four EPOCH early childhood obesity prevention interventions: A multi-methods study.

Childhood obesity is a global problem. Early obesity prevention interventions are complex and differ in effectiveness. Novel frameworks, taxonomies and experience from the Early Prevention of Obesity in CHildren (EPOCH) trials were applied to unpack interventions. Deconstruct interventions into their components (target behaviours, delivery features and behaviour change techniques [BCTs]). Identify lessons learned and future recommendations for intervention planning, delivery, evaluation and implementation. This multi-methods study deconstructed the four EPOCH interventions into target behaviours, delivery features and BCTs from unpublished and published materials using systematic frameworks. Additionally, semi-structured interviews were conducted with intervention facilitators and principal investigators. Each trial targeted between 10 and 14 obesity-related behaviours. Key variations in delivery features related to intensity, delivery mode and tailoring. BCTs consistently used across trials included goal-setting, social support, shaping knowledge, role-modelling and credible source. Recommendations from interview analyses include the importance of stakeholder collaboration and consideration of implementation throughout the study process. The combination of frameworks, methodologies and interviews used in this study is a major step towards understanding complex early obesity prevention interventions. Future work will link systematic intervention deconstruction with quantitative models to identify which intervention components are most effective and for whom.

Translation of two healthy eating and active living support programs for parents of 2\u20136\u2009year old children: a parallel partially randomised preference trial protocol (the \u2018time for healthy habits\u2019 trial)

BackgroundParents 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.MethodsParticipants 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.DiscussionTo 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.Trial registrationUTN: U1111–1228-9748, ACTRN: 12619000396123p.

Interventions commenced by early infancy to prevent childhood obesity—The EPOCH Collaboration: An individual participant data prospective meta‐analysis of four randomized controlled trials

Childhood obesity is a significant global problem. Childhood obesity prevention interventions may be more effective when started very early in life before metabolic and behavioural patterns are established. A prospectively planned, individual participant data meta-analysis of four randomized controlled trials. Participants were first-time mothers of term infants. Trial interventions commenced during pregnancy or early infancy and comprised education and support delivered via group sessions and/or home visits. Control group families accessed existing local well-child health care. The primary outcome was body mass index (BMI) z score at 18 to 24 months; 2196 mother-child dyads were available for analysis. Intervention children had lower BMI z scores at 18 to 24 months than control children (-0.12 adjusted mean; 95% confidence interval, -0.22 to -0.02, P = .017). There was some evidence that the BMI z score reduction was greater in settings with limited well-child health care programmes (interaction P value = .03). Improvements were also detected in television viewing time, feeding practices, and breastfeeding duration. Parent-focused intervention programmes that commence by early infancy and which aim to establish a trajectory of healthy lifestyle behaviours produced a modest but statistically significant reduction in BMI z score, which if replicated on a wider scale may have important public health implications.

Understanding the association between mother's education level and effectiveness of a child obesity prevention intervention: a secondary analysis of an RCT.

to explain differences in effectiveness of paediatrician-led motivational interviewing (MI) in decreasing body mass index (BMI) between children of mothers with low or high education level. secondary analysis of a randomised control trial. individually randomized controlled trial previously conducted from 2011 to 2013 in the province of Reggio Emilia (Emilia-Romagna Region, Northern Italy). Eligible participants included in the trial were 372 (187 in the MI group and 185 in the control group) overweight children (BMI percentile >= 85th and < 95th) aged between 4 and 7 years, residing in the province of Reggio Emilia and under the care of paediatrician for >= 12 months. The intervention included 5 MI sessions based on the transtheoretical model of addiction and behavioural change delivered at 1, 4, 7, and 12 months after the baseline visit, when families had to define specific goals in changing physical activity (PA) and diet behaviours. primary: BMI score variation (ΔBMI) from baseline to 12 months; secondary: percentage of changes in parent-reported PA and dietary behaviours. a significant effect of MI on ΔBMI in children whose mothers had high education level (ΔBMI = -0.62; 95%CI -0.92;-0.32) were observed. Children of women with high education level in MI group had more improvements in set unstructured PA, decreasing screen time and sweet snacks consumption, while children with less educated mothers had improvements in consuming more vegetable soup and less desserts, sweet snacks, and sugary beverages. Highly educated mothers chose for their children to drink fewer sugary beverages and to increase PA. Less educated mothers most frequently chose as goals having breakfast, eating more fruit and vegetables, eating fewer snacks, and having less screen time. Overall achievement was similar in the two strata for diet goals, but higher for PA goals in the high education level stratum. MI intervention was not effective in reducing BMI in children of mothers with low education level. This does appear to be weakly or not associated with goal choices and achievement within MI, it is rather an effect of unmeasured behaviours which possibly mediate association between MI and BMI reduction.

A collaborative approach to developing sustainable behaviour change interventions for childhood obesity prevention: Development of the Choosing Healthy Eating for Infant Health (CHErIsH) intervention and implementation strategy.

There is growing recognition of the need for effective behaviour change interventions to prevent chronic diseases that are feasible and sustainable and can be implemented within routine health care systems. Focusing on implementation from the outset of intervention development, and incorporating multiple stakeholder perspectives to achieve this, is therefore essential. This study explores the development of the Choosing Healthy Eating for Infant Health (CHErIsH) childhood obesity prevention intervention and implementation strategy to improve infant feeding behaviours. Five qualitative and quantitative evidence syntheses, two primary qualitative studies, and formal/informal consultations were conducted with practice, policy, research, and parent stakeholders. The Behaviour Change Wheel was used to guide the integration of findings. The CHErIsH intervention targets parent-level behaviour change and comprises (1) brief verbal messages and (2) trustworthy resources, to be delivered by health care professionals (HCPs) during routine infant vaccination visits. The implementation strategy targets HCP-level behaviour change and comprises (1) a local opinion leader, (2) incentivized training, (3) HCP resources and educational materials, (4) electronic delivery prompts, (5) awareness-raising across all primary care HCPs, and (6) local technical support. This study provides a rigorous example of the development of an evidence-based intervention aimed at improving parental infant feeding behaviours, alongside an evidence-based behaviour change strategy to facilitate implementation and sustainability in primary care. This approach demonstrates how to systematically incorporate multiple stakeholder perspectives with existing literature and move from multiple evidence sources to clearly specified intervention components for both the intervention and implementation strategy. Statement of Contribution What is already known? Incorporating insights from practice, policy, and public/patient stakeholders plays a key role in developing behaviour change interventions that are feasible and sustainable and can be implemented within routine health care systems. However, there are limited examples that provide in-depth guidance of how to do this using a systematic approach. What this study adds? This study describes an innovative use of the Behaviour Change Wheel to integrate multiple sources of evidence collected from practice, policy, research, and parent stakeholders to concurrently develop an evidence-based intervention to improve parental infant feeding behaviours and an implementation strategy to facilitate sustainable delivery by health care professionals in routine primary care.

Starting Early Program Impacts on Feeding at Infant 10 Months Age: A Randomized Controlled Trial.

Background: Disparities in obesity-promoting feeding patterns begin in pregnancy and infancy, underscoring the need for early primary prevention in high-risk groups. We sought to determine the impact of a primary care-based child obesity prevention intervention beginning during pregnancy on maternal infant feeding practices, knowledge, and styles at 10 months in low-income Hispanic families. Methods: The Starting Early Program (StEP) randomized controlled trial enrolled pregnant women at a third trimester visit. Women (n = 533) were randomized to standard care or an intervention with prenatal/postpartum individual nutrition counseling and nutrition and parenting support groups coordinated with pediatric visits. Feeding practices (breastfeeding, family meals, juice, and cereal in the bottle) were assessed using questions from the Infant Feeding Practices Study II. Feeding styles were assessed using the Infant Feeding Style Questionnaire. We analyzed impacts on feeding practices, knowledge, and styles using regression analyses adjusting for covariates. Results: Four hundred twelve mothers completed 10-month assessments. Intervention mothers were more likely to give breast milk as the only milk source [adjusted odds ratio (AOR) 1.65, 95% confidence interval (CI) 1.06-2.58] and have daily family meals (AOR 1.91, 95% CI 1.19-3.05), and less likely to give juice (AOR 0.60, 95% CI 0.39-0.92) or cereal in the bottle (AOR 0.54, 95% CI 0.30-0.97) compared to controls. Intervention mothers were more likely to exhibit lower pressuring, indulgent and laissez-faire feeding styles, and to have higher knowledge. Attending a greater number of group sessions increased intervention impacts. Conclusions: StEP led to reduced obesity-promoting feeding practices and styles, and increased knowledge and provides great potential for population-scalability.

Supporting healthy lifestyle behaviours in families attending community playgroups: parents\u2019 perceptions of facilitators and barriers

BackgroundEstablishing healthy nutrition, activity, and sleep behaviours early in life is a key strategy in childhood obesity prevention. Parents are the primary influence on the development and establishment of obesity-related behaviours in young children. There is evidence that autonomy supporting parenting practices are crucial for the development of self-regulation and the internalisation of healthy behaviours in children. It is therefore imperative that parenting practices are targeted as part of an obesity prevention intervention. However, there is limited understanding of barriers and facilitators to parents using autonomy supporting parenting practices with their children aged 0–5 years. Therefore, the aim of the study was to identify barriers and facilitators to using autonomy supporting parenting practices. A secondary aim was to determine parent preferences in respect to an intervention program to be delivered in community playgroups.MethodsParents were recruited through Playgroup Queensland (PGQ), a not-for-profit organisation in Brisbane, Australia, to attend a focus group during their usual playgroup session. The focus group interview guide was designed to promote discussion among the participants in respect to their shared experiences as parents of young children. The focus group transcripts were coded and analysed using qualitative content analysis. Five focus groups with parents (n = 30) were conducted in May 2018. Most of the participants were mothers [1], and the majority (76%) had a child at playgroup aged between 2 and 4 years.ResultsThe support and guidance received from other parents at playgroup was a facilitator to autonomy supporting parenting practices. Barriers included beliefs around the need to use rewards to encourage child eating, beliefs around the need for screens as babysitters, and feeling disempowered to change sleep behaviours. Parents were enthusiastic about a potential program that would leverage off the existing playgroup support networks, but they did not want to be “educated”, or to lose their “playgroup time” to an intervention. Rather they wanted strategies and support to deal with the frustrations of food, screen and sleep parenting.ConclusionThese results will be used to inform the development of a childhood obesity prevention intervention to be delivered in a community playgroup setting.

Association between Early Maternal Depression and Child Growth: A Group-Based Trajectory Modeling Analysis.

Background: Childhood overweight and obesity have become a primary social and public health concern. Over the past 30 years, rates of childhood overweight and obesity in the United States have increased dramatically from 6% to 35%. A potential risk factor of interest is maternal depression. To date, there are mixed findings available on the association between maternal depression and childhood obesity development, and there is a dearth of longitudinal research available. To address these gaps in the literature, this study investigated the association between maternal depression at age 1 and/or age 3 years and childhood obesity longitudinally. Methods: This study used data from the Fragile Families Child Wellbeing Study (FFCWS) to investigate the research questions. FFCWS is a national dataset that has information on 4898 women, and their children, from predominantly nonmarital, low-income minority groups in the United States. This study used information collected at the birth of the child (wave 1) through age 9 years (wave 5). The analytic sample consisted of 3500 mother-children dyads. Group-based trajectory modeling and multivariable logistic regression were used. Results: The results indicated that there was no association between maternal depression and childhood obesity development in this sample of low-income and mostly minority participants. Maternal prepregnancy BMI, number of biological children in the house, and Latino ethnicity were significant predictors of risky growth trajectories in the full sample. Suggestions for designing childhood obesity prevention interventions based on research are discussed.

Impact of Parent Engagement in Childhood Obesity Prevention Interventions on Anthropometric Indices among Preschool Children: A Systematic Review.

Background: Home environment, modeling of weight-related behaviors, and general parenting style are very important predictors of obesity in children. The effect of parent engagement in prevention of obesity in children is not clear. The main objective of this systematic review was to address the effects of parent engagement in obesity prevention interventions on anthropometric changes among preschool children. Methods: PubMed/Medline, Cochrane Library, ISI Web of Knowledge, Scopus, Science Direct, and Google Scholar were searched. Eligible studies were randomized controlled trials in last 10 years (from 2008 until February 14, 2018), which had a parent engagement in obesity prevention interventions (as an intervention) and children's anthropometric indices (as an outcome). Results: Twenty-six studies were included. Half of studies targeted both parents and children, and the rest targeted only parents. Types of interventions ranged from a simple motivational interviewing to professional skill training approaches. Studies that targeted overweight or obese children in their intervention containing training sessions followed by maintenance for parents and those that focused on individual support for overweight children and their parents, resulted in higher improvement in BMI and other outcomes. Conclusions: Anthropometric indices and BMI are not appropriate for reflecting the effectiveness of parent engagement in obesity prevention interventions. Having an individual component in the intervention and focusing more on parents vs. children in the intervention may result in improvement in anthropometric outcomes. Focusing on weight-related behaviors as the main outcome in both, children and parents, rather than anthropometric indices, is highly recommended for future reviews.

Perceptions and Impact of a Youth-led Childhood Obesity Prevention Intervention among Youth-leaders

ABSTRACT Objective: To evaluate the impact of a youth-led nutrition intervention on youth-leaders themselves Design: Mixed methods, including: in-depth interviews and a quasi-experimental quantitative study comparing youth-leaders and nonparticipant comparison youth Analysis: Qualitative analysis using direct content analysis. Difference-in-differences analyses assessing quantitative program impact. Results: Youth-leaders perceived that the intervention impacted themselves, the youth-participants, and their respective social networks. Youth-leaders experienced greater increases in intentions to eat healthfully (p = .04), and greater decreases in support for healthy eating from their friends (p = .01), than the comparison group. Conclusions/Implications: Youth-leaders reported multiple levels of intervention impact, and increased intentions for healthy eating; however, additional research is needed to enhance impact on behavioral outcomes.
