The Healthy Children, Strong Families intervention promotes improvements in nutrition, activity and body weight in American Indian families with young children

Factors of success, barriers, and the role of frontline workers in Indigenous maternal-child health programs: a scoping review

BACKGROUND

Despite considerable investment in maternal-child programs in Canada, there has been little positive impact on the health of Indigenous mothers and their children. The reasons for this are unclear and there is a need to identify how such programs can be successfully implemented. Community input is essential for successful programs; however, it is unclear what the contributions of frontline workers have been in the health program process, i.e., program development, delivery, and evaluation. Based on these identified gaps, this scoping review aimed to: (1) identify factors of success and barriers to successful Indigenous maternal-child community health programs for mothers and their children aged 0-6 years; and (2) explore how frontline workers are included in the program process.

METHODS

This scoping review was completed using the Arksey and O'Malley framework, informed by Levac et al. Four data bases (Medline, CINAHL, Embase, and Scopus), grey literature, and reference lists were searched for relevant materials from 1990-2019. Data was extracted from included articles and analysed using descriptive statistics, thematic analysis with the Braun and Clarke framework, and a Principal Component Analysis.

RESULTS

Forty-five peer-reviewed and grey articles were included in the review. Factors of program success included: relationship building; cultural inclusion; knowledge transmission styles; community collaboration; client-centred approaches; Indigenous staff; and operational considerations. Barriers included: impacts of colonization; power structure and governance; client and community barriers to program access; physical and geographical challenges; lack of staff; and operational deficits. Frontline workers were found to have a role in program delivery (n = 45) and development (n = 25). Few (n = 6) had a role in program evaluation.

CONCLUSION

Although a better understanding of the frontline worker role in maternal-child health programs was obtained from the review, in a large proportion of literature the authors could not determine if the role went beyond program delivery. In addition, no direct input from frontline workers and their perspectives on program success or barriers were identified, suggesting areas to explore in future research. This review's findings have been applied to inform a community-based participatory research project and may also help improve the development, delivery, and evaluation of Indigenous maternal-child health programs.

Components in downstream health promotions to reduce sugar intake among adults: a systematic review

Excessive sugar consumption is well documented as a common risk factor for many Non-Communicable Diseases (NCDs). Thus, an adequate intervention description is important to minimise research waste and improve research usability and reproducibility. A systematic review was conducted to identify components in published evidence interventions pertaining to the health promotions on reducing sugar intake among adults. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and used the Mixed Methods Appraisal Tool (MMAT) for quality appraisal. The period for the selected study was from 2000 to 2022, and articles were retrieved from Web of Science (WOS), Medline, Scopus, and PubMed. The target population was adults aged 18 years old and above who underwent intervention to assess the changes in their sugar intake. Data sources and all human epidemiologic studies were included. Out of the 9,333 papers identified, 25 were included. The overall quality of evidence of the studies was considered moderate. Apart from the characteristics of the reviewed studies, components of interventions are including the basis of theoretical or model for the intervention, which majority use Social Cognitive Theory, followed by PRECEDE-PROCEED model, socio-ecological and process-improvement theories and Transtheoretical Model; providers, who are commercial provider, qualified nutritionist, professor of nutrigenomics and nutrigenetics, doctor, dietitian nutritionist, lifestyle coaches, and junior public health nurses; duration of the intervention and follow-up time, varies from as short as one month to as long as 24 months; material provided either softcopy or hardcopy; tailoring approach, based on the individual goals, the process of change, genotype analysis, beliefs, barriers, and sociocultural norms; delivery mechanism either face-to-face or technology-mediated; and tools to measure the sugar consumption outcome mostly used Food Frequency Questionnaire (FFQ), besides 24-h dietary recalls, and food diaries. There are various components in downstream health promotion to reduce sugar intake among adults that can be adapted according to the local health promotion and intervention context. More well-designed interventions using integration components are encouraged in further studies.

Systems map of interventions to improve dietary intake of pre-school aged children: A scoping review

Implementation and sustaining impact of early childhood nutrition interventions in practice remains a challenge. An understanding of the extent to which determinants across multiple levels of the food system are being addressed may improve success. This literature review aimed to synthesise the evidence on interventions targeting dietary intake and eating behaviours in preschool children using a systems approach. Eligible studies included intervention studies targeting the dietary intake of preschool children aged 2-5 years in high income countries, published in English after January 2000. Interventions were categorised to the Determinants of Nutrition and Eating (DONE) framework for children developed and evaluated by experts across multiple fields. The framework maps and ranks 411 factors driving eating behaviours and nutrition and can be used to systematically summarise determinants. DONE ranks each determinant for its perceived research priority. A total of 160 eligible studies were identified. Most interventions targeted interpersonal (n = 101, 63.1%) and individual (n = 85, 53.1%) level determinants, with fewer targeting environmental (n = 55, 34.4%) and policy level (n = 17, 10.6%) determinants. The most frequently addressed determinants were Parental Resources and Risk Factors (n = 85) and Children's Food Knowledge, Skills and Abilities (n = 67). These determinants had a Moderate research priority rating. Home Food Availability and Accessibility at the environmental level is classified as the highest research priority, however, only 15 of 160 interventions addressed this determinant. This review highlights home food availability and accessibility as potential leverage points for future interventions to improve children's dietary intake and eating behaviours.

Culturally adapting an evidence-based intervention to promote a healthy diet and lifestyle for Yup'ik Alaska native communities

Underserved populations are at increased risk for obesity and related cardiovascular disease, type 2 diabetes, and other chronic diseases. Lack of access to healthy foods, sedentary behaviour, and other social environmental factors contribute to disease risk. Yup'ik Alaska Native communities are experiencing lifestyle changes that are likely to affect their cardiometabolic risks. Barrera & Castro's Cultural Adaptation Framework was used to adapt an evidence-based intervention (EBI) originally designed for Latino communities for use in Yup'ik communities. Focus groups and key informant interviews were held in two Yup'ik communities. Major themes included causes of obesity, barriers and facilitators to healthy foods and physical activity, and intervention ideas. The adaptation process was guided by a Community Planning Group of Yup'ik women and included information gathering, preliminary adaptation design, preliminary adaptation tests, and adaptation refinement. Two of the adapted educational modules were pilot tested. Involving community members as co-researchers in cultural adaptation is vital for an EBI to be effective in another population. Small group gatherings led by local lay health workers are culturally appropriate and may be an effective health promotion model in Yup'ik communities. Social environmental factors affecting healthy food availability and physical activity need further exploration.

Family-centred interventions for Indigenous early childhood well-being by primary healthcare services

BACKGROUND

Primary healthcare, particularly Indigenous-led services, are well placed to deliver services that reflect the needs of Indigenous children and their families. Important characteristics identified by families for primary health care include services that support families, accommodate sociocultural needs, recognise extended family child-rearing practices, and Indigenous ways of knowing and doing business. Indigenous family-centred care interventions have been developed and implemented within primary healthcare services to plan, implement, and support the care of children, immediate and extended family and the home environment. The delivery of family-centred interventions can be through environmental, communication, educational, counselling, and family support approaches.

OBJECTIVES

To evaluate the benefits and harms of family-centred interventions delivered by primary healthcare services in Canada, Australia, New Zealand, and the USA on a range of physical, psychosocial, and behavioural outcomes of Indigenous children (aged from conception to less than five years), parents, and families.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was 22 September 2021.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), cluster RCTs, quasi-RCTs, controlled before-after studies, and interrupted time series of family-centred care interventions that included Indigenous children aged less than five years from Canada, Australia, New Zealand, and the USA. Interventions were included if they met the assessment criteria for family-centred interventions and were delivered in primary health care. Comparison interventions could include usual maternal and child health care or one form of family-centred intervention versus another.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were 1. overall health and well-being, 2. psychological health and emotional behaviour of children, 3. physical health and developmental health outcomes of children, 4. family health-enhancing lifestyle or behaviour outcomes, 5. psychological health of parent/carer. 6. adverse events or harms. Our secondary outcomes were 7. parenting knowledge and awareness, 8. family evaluation of care, 9. service access and utilisation, 10. family-centredness of consultation processes, and 11. economic costs and outcomes associated with the interventions. We used GRADE to assess the certainty of the evidence for our primary outcomes.

MAIN RESULTS

We included nine RCTs and two cluster-RCTs that investigated the effect of family-centred care interventions delivered by primary healthcare services for Indigenous early child well-being. There were 1270 mother-child dyads and 1924 children aged less than five years recruited. Seven studies were from the USA, two from New Zealand, one from Canada, and one delivered in both Australia and New Zealand. The focus of interventions varied and included three studies focused on early childhood caries; three on childhood obesity; two on child behavioural problems; and one each on negative parenting patterns, child acute respiratory illness, and sudden unexpected death in infancy. Family-centred education was the most common type of intervention delivered. Three studies compared family-centred care to usual care and seven studies provided some 'minimal' intervention to families such as education in the form of pamphlets or newsletters. One study provided a minimal intervention during the child's first 24 months and then the family-centred care intervention for one year. No studies had low or unclear risk of bias across all domains. All studies had a high risk of bias for the blinding of participants and personnel domain. Family-centred care may improve overall health and well-being of Indigenous children and their families, but the evidence was very uncertain. The pooled effect estimate from 11 studies suggests that family-centred care improved the overall health and well-being of Indigenous children and their families compared no family-centred care (standardised mean difference (SMD) 0.14, 95% confidence interval (CI) 0.03 to 0.24; 2386 participants). We are very uncertain whether family-centred care compared to no family-centred care improves the psychological health and emotional behaviour of children as measured by the Infant Toddler Social Emotional Assessment (ITSEA) (Competence domain) (mean difference (MD) 0.04, 95% CI -0.03 to 0.11; 2 studies, 384 participants). We assessed the evidence as being very uncertain about the effect of family-centred care on physical health and developmental health outcomes of children. Pooled data from eight trials on physical health and developmental outcomes found there was little to no difference between the intervention and the control groups (SMD 0.13, 95% CI -0.00 to 0.26; 1961 participants). The evidence is also very unclear whether family-centred care improved family-enhancing lifestyle and behaviours outcomes. Nine studies measured family health-enhancing lifestyle and behaviours and pooled analysis found there was little to no difference between groups (SMD 0.16, 95% CI -0.06 to 0.39; 1969 participants; very low-certainty evidence). There was very low-certainty evidence of little to no difference for the psychological health of parents and carers when they participated in family-centred care compared to any control group (SMD 0.10, 95% CI -0.03 to 0.22; 5 studies, 975 parents/carers). Two studies stated that there were no adverse events as a result of the intervention. No additional data were provided. No studies reported from the health service providers perspective or on outcomes for family's evaluation of care or family-centredness of consultation processes.

AUTHORS' CONCLUSIONS

There is some evidence to suggest that family-centred care delivered by primary healthcare services improves the overall health and well-being of Indigenous children, parents, and families. However, due to lack of data, there was not enough evidence to determine whether specific outcomes such as child health and development improved as a result of family-centred interventions. Seven of the 11 studies delivered family-centred education interventions. Seven studies were from the USA and centred on two particular trials, the 'Healthy Children, Strong Families' and 'Family Spirit' trials. As the evidence is very low certainty for all outcomes, further high-quality trials are needed to provide robust evidence for the use of family-centred care interventions for Indigenous children aged less than five years.

EASO and EFAD Position Statement on Medical Nutrition Therapy for the Management of Overweight and Obesity in Children and Adolescents

INTRODUCTION

This position statement on medical nutrition therapy in the management of overweight or obesity in children and adolescents was prepared by an expert committee convened by the European Association for the Study of Obesity (EASO) and developed in collaboration with the European Federation of the Associations of Dietitians (EFAD).

METHODS

It is based on the best evidence available from systematic reviews of randomized controlled trials on child and adolescent overweight and obesity treatment and other relevant peer-reviewed literature.

RESULTS

Multicomponent behavioural interventions are generally considered to be the gold standard treatment for children and adolescents living with obesity. The evidence presented in this position statement confirms that dietary interventions can effectively improve adiposity-related outcomes. Dietary strategies should focus on the reduction of total energy intake through promotion of food-based guidelines that target modification of usual eating patterns and behaviours. These should target increasing intakes of nutrient-rich foods with a lower energy density, specifically vegetables and fruits, and a reduction in intakes of energy-dense nutrient-poor foods and beverages. In addition, higher intensity, longer duration treatments, delivered by interventionists with specialized dietetic-related skills and co-designed with families, are associated with greater treatment effects.

DISCUSSION

Such interventions should be resourced adequately so that they can be implemented in a range of settings and in different formats, including digital or online delivery, to enhance accessibility.

Home- and Community-Based Interventions for Physical Activity and Early Child Development: A Systematic Review of Effective Strategies

This systematic review examined the effects of home/family and community-based interventions on physical activity (PA) and developmental outcomes in early childhood. A search strategy was employed using four electronic databases (Academic Search Complete, CINAHL Complete, MEDLINE, and SPORTDiscus). Interventions investigating weight status (i.e., BMI), physical activity, sedentary behavior, and/or motor proficiency that took place in home, family, or community settings were assessed. Studies were eligible if they were peer-reviewed, available in English, published between 2011 and 2021, and if samples consisted of healthy young children (2-5 years old). There were 24 studies retained (8351 participants) spanning from the United States (n = 12), Australia (n = 3), Canada (n = 2), Switzerland (n = 2), Finland (n = 2), Netherlands (n = 1), and other Eastern European countries (n = 2). There were 19 studies that incorporated home/family-based approaches and 14 studies that incorporated community-based approaches. Studies ranged in intervention duration from 6 weeks to 24 months. It suggests that improving PA participation in young children was especially challenging to solicit improvement (only 25% of all studies found significant improvement in PA after intervention). Distributing educational material to parents/families, consistent, direct contact with parents, and encouraging community engagement were identified as effective strategies to promote physical activity, healthy weight status, and motor skills in young children.

Community-Based Participatory Research (CBPR) to Enhance Participation of Racial/Ethnic Minorities in Clinical Trials: A 10-Year Systematic Review

There has not been a significant improvement in the rate of clinical trial accrual in more than 20 years. Worse, the challenge of inadequate representation among racial and ethnic minorities also persists, deepening disparities in health. Community-Based Participatory Research (CBPR) is a participatory communication method that centers on effective dialogue between researchers and community stakeholders with the goal of creating an equitable partnership for health and social change. The objective of the current study was to provide an update since a systematic review in 2012, on the current status of the empirical research, with a particular focus on the elements of CBPR methods used to improve the rate of accrual of members of racial and ethnic minority communities for clinical trials. Our systematic review found a large increase in the number of CBPR related studies and studies related to racial and ethnic representation in research. More than 85% of studies employing CBPR methods saw statistically positive outcomes. Specifically, the elements of CBPR that are associated with these positive outcomes include community partner participation in (1) a study advisory committee, (2) data collection, (3) the development of interventions, and (4) participant recruitment. However, the results of our study indicate that researchers need to be more transparent about the extent of community participation as well as more thoroughly and accurately describe the nature of the partnership with members of minority communities in order to build upon the scientific literature on community-engaged methods.

Preventing and treating childhood overweight and obesity in children up to 5 years old: A systematic review by intervention setting

The prevalence of childhood obesity is increasing worldwide with long-term health consequences. Effective strategies to stem the rising childhood obesity rates are needed but systematic reviews of interventions have reported inconsistent effects. Evaluation of interventions could provide more practically relevant information when considered in the context of the setting in which the intervention was delivered. This systematic review has evaluated diet and physical activity interventions aimed at reducing obesity in children, from birth to 5 years old, by intervention setting. A systematic review of the literature, consistent with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, was performed. Three electronic databases were searched from 2010 up to December 2020 for randomised controlled trials aiming to prevent or treat childhood obesity in children up to 5 years old. The studies were stratified according to the setting in which the intervention was conducted. Twenty-eight studies were identified and included interventions in childcare/school (n = 11), home (n = 5), community (n = 5), hospital (n = 4), e-health (n = 2) and mixed (n = 1) settings. Thirteen (46%) interventions led to improvements in childhood obesity measures, including body mass index z-score and body fat percentage, 12 of which included both parental/family-based interventions in conjunction with modifying the child's diet and physical activity behaviours. Home-based interventions were identified as the most effective setting as four out of five studies reported significant changes in the child's weight outcomes. Interventions conducted in the home setting and those which included parents/families were effective in preventing childhood obesity. These findings should be considered when developing optimal strategies for the prevention of childhood obesity.

Family‐based interventions for preventing overweight or obesity among preschoolers from racial/ethnic minority groups: A scoping review

Objective

This scoping review aimed to synthesize the published literature on family‐based childhood obesity prevention interventions from 2015 to 2021 that focused on children 2–5 years of age from racial and/or ethnic minority households.

Methods

A PICOS (population, intervention, comparison, outcome, and setting) framework was used to guide the development of the research question, search strategy, and inclusion/exclusion criteria. To be included, the study must have been a randomized controlled trial or quasi‐experimental trial that enrolled participants 2–5 years of age and their caregivers who identified as being from a racial and/or ethnic minority group in the United States. The study must have also examined a family‐based intervention that incorporated components to prevent childhood obesity (i.e., fruits and vegetable intake, parental responsive feeding, physical activity), be conducted in a remote (i.e., online, text, mail), home, community, primary care setting, or early childhood education institution setting, and report on body mass index (BMI, kg/m²), BMI z‐score, anthropometric measures (weight, waist circumference, fat mass, etc.), changes in health behaviors, or increase in nutritional knowledge.

Results

Fourteen individual studies were identified. Most interventions used multiple components for promoting nutritional knowledge and behavioral changes among families. Eight interventions included culturally tailored components targeting four aspects: (1) language barriers, (2) food choices, (3) relationships between family members, and (4) rapport building.

Conclusions

There is limited research in this field focusing on children from racial and/or ethnic minority groups. Future efforts should invest in developing culturally appropriate interventions for these groups.

Involvement of Non-Parental Caregivers in Obesity Prevention Interventions among 0-3-Year-Old Children: A Scoping Review

INTRODUCTION

We examined the scope of literature including non-parental caregiver involvement in child obesity prevention interventions.

METHODS

We conducted a scoping review following the Arksey and O'Malley framework, including only studies reporting the effect of an intervention on growth, weight, or early childhood obesity risk among children ages 0 to three years, published between 2000 and 2021. Interventions that did not include non-parental caregivers (adults regularly involved in childcare other than parents) were excluded.

RESULTS

Of the 14 studies that met the inclusion criteria, all were published between 2013 and 2020, and most interventions (n = 9) were implemented in the United States. Eight of the 14 interventions purposefully included other non-parental caregivers: five included both parents and non-parental caregivers, and the remaining three included only non-parental caregivers. Most interventions (n = 9) showed no significant impact on anthropometric outcomes. All interventions found improvements in at least one behavioral outcome (e.g., food groups intake (n = 5), parental feeding practices (n = 3), and screen time (n = 2)). This review can inform future interventions that plan to involve non-parental caregivers, which may be beneficial in shaping early health behaviors and preventing obesity early in life.

Identifying effective intervention strategies to reduce children's screen time: a systematic review and meta-analysis

BACKGROUND

Excessive screen time ([Formula: see text] 2 h per day) is associated with childhood overweight and obesity, physical inactivity, increased sedentary time, unfavorable dietary behaviors, and disrupted sleep. Previous reviews suggest intervening on screen time is associated with reductions in screen time and improvements in other obesogenic behaviors. However, it is unclear what study characteristics and behavior change techniques are potential mechanisms underlying the effectiveness of behavioral interventions. The purpose of this meta-analysis was to identify the behavior change techniques and study characteristics associated with effectiveness in behavioral interventions to reduce children's (0-18 years) screen time.

METHODS

A literature search of four databases (Ebscohost, Web of Science, EMBASE, and PubMed) was executed between January and February 2020 and updated during July 2021. Behavioral interventions targeting reductions in children's (0-18 years) screen time were included. Information on study characteristics (e.g., sample size, duration) and behavior change techniques (e.g., information, goal-setting) were extracted. Data on randomization, allocation concealment, and blinding was extracted and used to assess risk of bias. Meta-regressions were used to explore whether intervention effectiveness was associated with the presence of behavior change techniques and study characteristics.

RESULTS

The search identified 15,529 articles, of which 10,714 were screened for relevancy and 680 were retained for full-text screening. Of these, 204 studies provided quantitative data in the meta-analysis. The overall summary of random effects showed a small, beneficial impact of screen time interventions compared to controls (SDM = 0.116, 95CI 0.08 to 0.15). Inclusion of the Goals, Feedback, and Planning behavioral techniques were associated with a positive impact on intervention effectiveness (SDM = 0.145, 95CI 0.11 to 0.18). Interventions with smaller sample sizes (n < 95) delivered over short durations (< 52 weeks) were associated with larger effects compared to studies with larger sample sizes delivered over longer durations. In the presence of the Goals, Feedback, and Planning behavioral techniques, intervention effectiveness diminished as sample size increased.

CONCLUSIONS

Both intervention content and context are important to consider when designing interventions to reduce children's screen time. As interventions are scaled, determining the active ingredients to optimize interventions along the translational continuum will be crucial to maximize reductions in children's screen time.

The Families and Schools for Health Project: A Longitudinal Cluster Randomized Controlled Trial Targeting Children with Overweight and Obesity

This cluster randomized controlled trial aimed at overweight and obese children compared three treatments. Two psychoeducation interventions for parents and children were conducted: Family Lifestyle (FL) focused on food and physical activity; Family Dynamics (FD) added parenting and healthy emotion management. A third Peer Group (PG) intervention taught social acceptance to children. Crossing interventions yielded four conditions: FL, FL + PG, FL + FD, and FL + FD + PG-compared with the control. Longitudinal BMI data were collected to determine if family- and peer-based psychosocial components enhanced the Family Lifestyle approach. Participants were 1st graders with BMI%ile >75 (n = 538: 278 boys, 260 girls). Schools were randomly assigned to condition after stratifying for community size and percent American Indian. Anthropometric data were collected pre- and post-intervention in 1st grade and annually through 4th grade. Using a two-level random intercept growth model, intervention status predicted differences in growth in BMI or BMI-M% over three years. Children with obesity who received the FL + FD + PG intervention had lower BMI gains compared to controls for both raw BMI (B = -0.05) and BMI-M% (B = -2.36). Interventions to simultaneously improve parent, child, and peer-group behaviors related to physical and socioemotional health offer promise for long-term positive impact on child obesity.

Measurement of screen time among young children aged 0-6 years: A systematic review

The impact of screen-based devices on children's health and development cannot be properly understood without valid and reliable tools that measure screen time within the evolving digital landscape. This review aimed to summarize characteristics of measurement tools used to assess screen time in young children; evaluate reporting of psychometric properties; and examine time trends related to measurement and reporting of screen time. A systematic review of articles published in English across three databases from January 2009 to April 2020 was undertaken using PROSPERO protocol (registration: CRD42019132599) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included articles measured screen time as outcome, exposure, or confounder in children 0-6 years. The search identified 35,868 records, 1035 full-text articles were screened for eligibility, and 622 met inclusion criteria. Most measures (60%) consisted of one to three items and assessed duration of screen time on a usual day. Few measures assessed content (11%) or coviewing (7%). Only 40% of articles provided a citation for the measure, and only 69 (11%) reported psychometric properties-reliability n = 58, validity n = 19, reliability and validity n = 8. Between 2009 and 2019, the number of published articles increased from 28 to 71. From 2015, there was a notable increase in the proportion of articles published each year that assessed exposure to mobile devices in addition to television. The increasing number of published articles reflects increasing interest in screen time exposure among young children. Measures of screen time have generally evolved to reflect children's contemporary digital landscape; however, the psychometric properties of measurement tools are rarely reported. There is a need for improved measures and reporting to capture the complexity of children's screen time exposures.

Health promotion interventions supporting Indigenous healthy ageing: a scoping review

Aging well is a priority in Canada and globally, particularly for older Indigenous adults experiencing an increased risk of chronic conditions. Little is known about health promotion interventions for older Indigenous adults and most literature is framed within Eurocentric paradigms that are not always relevant to Indigenous populations. This scoping review, guided by Arksey and O'Malley's framework and the PRISMA-ScR Checklist, explores the literature on Indigenous health promoting interventions across the lifespan, with specific attention to Indigenous worldview and the role of older Indigenous adults within these interventions. To ensure respectful and meaningful engagement of Indigenous peoples, articles were included in the Collaborate or Shared Leadership categories on the Continuum of Engagement. Fifteen articles used Indigenous theories and frameworks in the study design. Several articles highlighted engaging Elders as advisors in the design and/or delivery of programs however only five indicated Elders were active participants. In this scoping review, we suggest integrating a high level of community engagement and augmenting intergenerational approaches are essential to promoting health among Indigenous populations and communities. Indigenous older adults are keepers of essential knowledge and must be engaged (as advisors and participants) in intergenerational health promotion interventions to support the health of all generations.

A Scoping Review of the Use of Indigenous Food Sovereignty Principles for Intervention and Future Directions

Indigenous food sovereignty (IFS) represents a community-led movement with potential to reduce health inequities, but no scoping review of the impact of taking an IFS approach on intervention research has been conducted. This review sought to: 1) describe intervention studies that employ IFS principles, and 2) describe the impact of studies using IFS principles on food access, eating patterns, diet quality, physical activity, and health. Through a literature review, 4 IFS principles were identified: 1) community ownership, 2) inclusion of traditional food knowledge, 3) inclusion and promotion of cultural foods, and 4) environmental/intervention sustainability. Twenty intervention studies published between January 1, 2000 and February 5, 2020 were included. Most of the studies that scored high in IFS principles saw a positive impact on diet. This review found evidence supporting the value of IFS principles in the development, implementation, and evaluation of health interventions for Indigenous communities.

Effectiveness of programs aimed at obesity prevention among Indigenous children: A systematic review

Given the significant health burden of childhood obesity, it is imperative that effective programs be better understood. When evaluating obesity prevention efforts, one must recognize the contextual factors which drive the disproportionate risk of obesity between populations. This systematic review sought to understand if programs aimed at obesity prevention and/or the promotion of healthy lifestyle behaviours for Indigenous children are effective. We conducted a search using Medline, EMBASE, PsychINFO, ERIC, CINAHL and iPORTAL databases from inception to August 13, 2019. We included experimental and quasi-experimental studies. The main outcomes of interest were change in anthropometrics, nutrition or physical activity. Our narrative synthesis included an assessment of study quality using the Effective Public Health Practice Project Quality assessment tool. A total of 34 studies met selection criteria. Most studies used a quasi-experimental design (n = 25) and were assessed as low to moderate quality (n = 32). Three studies showed a significant change in anthropometric measures, 14 studies demonstrated at least one significant nutrition-related behaviour or dietary-pattern change, and six studies demonstrated a significant impact on physical activity. This systematic review of programs to prevent obesity among Indigenous children finds a limited impact on anthropometric measurements. Future studies must prioritize Indigenous knowledge and ways of knowing to lead all phases of development, implementation, and evaluation of programs.

Caring for American Indian and Alaska Native Children and Adolescents

American Indian and Alaska Native (AI/AN) populations have substantial health inequities, and most of their disease entities begin in childhood. In addition, AI/AN children and adolescents have excessive disease rates compared with the general pediatric population. Because of this, providers of pediatric care are in a unique position not only to attenuate disease incidence during childhood but also to improve the health status of this special population as a whole. This policy statement examines the inequitable disease burden observed in AI/AN youth, with a focus on toxic stress, mental health, and issues related to suicide and substance use disorder, risk of and exposure to injury and violence in childhood, obesity and obesity-related cardiovascular risk factors and disease, foster care, and the intersection of lesbian, gay, bisexual, transgender, queer, and Two-Spirit and AI/AN youth. Opportunities for advocacy in policy making also are presented.

Determining Effective Nutrition Intervention Strategies and the Subsequent Impact on Nutrition Knowledge, Dietary Adherence, and Health Outcomes among American Indian/Alaska Native Youth (2-18 Years of Age): a Systematic Review

The PRISMA style literature review was used to determine effective nutrition intervention strategies and their subsequent impact on nutrition knowledge, dietary adherence, and health outcomes among American Indian/Alaskan Native (AI/AN) youth. Peer-reviewed articles published between January 1980 and December 2019 were extracted from PubMed, CINAHL, Cochrane, and PsychInfo databases. A 4-point inclusion criterion was established to include articles with AI/AN youth, nutrition intervention, and presented health outcomes. A quality criteria checklist was used to assess the articles. A total of 12 studies were included in this study. Interventions that incorporated cultural adaptations (e.g., storytelling), theoretical frameworks (e.g., community-based participatory), active learning (e.g., cooking), tribal partnership, and caregiver involvement slightly improved nutrition knowledge, dietary adherence, and health outcomes. Overall, this review revealed that incorporating cultural aspects with input from the community in a nutrition program has a positive impact on AI/AN youths. Steps can be taken at the policy level to direct obesity and non-communicable disease prevention efforts among AI/AN youth.

Language, Culture, and Collectivism: Uniting Coalition Partners and Promoting Holistic Health in the Menominee Nation

Recent perspectives on Indigenous health have recognized language, culture, and values as central to well-being and recovery from historical trauma. Health coalitions, which identify community health concerns and mobilize members to implement strategies for change, have begun to shift their focus from programs to policy, systems, and environmental change but have been slower to recognize the possibilities of centering Indigenous ways of being in their work. This article details a case study of the Menominee Wellness Initiative, an Indigenous health coalition that has increasingly made language, culture, and collective values the focus of their health promotion work, and often due to the participation and influence of community organizers in the coalition. The study is presented as a collaborative writing effort between coalition members and academic partners. Qualitative data were gathered through observations of coalition meetings; in-depth, semistructured interviews with coalition members; and interactive data analysis discussions within the collaborative writing team. In the results, we describe how the shift in the coalition's framework came to be and the influence this shift has had on the coalition, its activities, and its community impacts. These findings illustrate and extend understanding of several principles of Collaborating for Equity and Justice and supports literature and practice related to health promotion through the centering of Indigenous ways.

Childhood Obesity Evidence Base Project: A Systematic Review and Meta-Analysis of a New Taxonomy of Intervention Components to Improve Weight Status in Children 2-5 Years of Age, 2005-2019

Objective: To evaluate the efficacy of childhood obesity interventions and conduct a taxonomy of intervention components that are most effective in changing obesity-related health outcomes in children 2-5 years of age. Methods: Comprehensive searches located 51 studies from 18,335 unique records. Eligible studies: (1) assessed children aged 2-5, living in the United States; (2) evaluated an intervention to improve weight status; (3) identified a same-aged comparison group; (4) measured BMI; and (5) were available between January 2005 and August 2019. Coders extracted study, sample, and intervention characteristics. Effect sizes [ESs; and 95% confidence intervals (CIs)] were calculated by using random-effects models. Meta-regression was used to determine which intervention components explain variability in ESs. Results: Included were 51 studies evaluating 58 interventions (N = 29,085; mean age = 4 years; 50% girls). Relative to controls, children receiving an intervention had a lower BMI at the end of the intervention (g = 0.10, 95% CI = 0.02-0.18; k = 55) and at the last follow-up (g = 0.17, 95% CI = 0.04-0.30; k = 14; range = 18-143 weeks). Three intervention components moderated efficacy: engage caregivers in praise/encouragement for positive health-related behavior; provide education about the importance of screen time reduction to caregivers; and engage pediatricians/health care providers. Conclusions: Early childhood obesity interventions are effective in reducing BMI in preschool children. Our findings suggest that facilitating caregiver education about the importance of screen time reduction may be an important strategy in reducing early childhood obesity.

A case study of using the He Pikinga Waiora Implementation Framework: challenges and successes in implementing a twelve-week lifestyle intervention to reduce weight in Māori men at risk of diabetes, cardiovascular disease and obesity

Background

Māori men have stark health inequities around non-communicable diseases. This study describes the case of a partnership attempting to develop and implement a culturally centred intervention through a collaborative partnership to potentially address the inequities. In particular, the partnership followed a participatory, co-design approach using the He Pikinga Waiora (HPW) Implementation Framework; the study presents lessons learnt in addressing health inequities following this framework.

Methods

The partnership involved a university research team and a Māori community health provider. They engaged with other stakeholders and several cohorts of Māori men through a co-design process to adapt a 12-week lifestyle intervention. The co-design process was documented through meeting notes and interviews with partners. Two cohorts participated in separate single group pre-intervention/post-intervention designs with multi-method data collection. Key outcome measures included weight loss, self-reported health, physical activity, and nutrition. Post-intervention data collection included qualitative data.

Results

The co-design process resulted in a strong and engaged partnership between the university team and the provider. There were significant challenges in implementing the intervention including having two additional partner organisations dropping out of the partnership just after the initial implementation phase. However, a flexible and adaptable partnership resulted in developing two distinct lifestyle interventions run with 32 Māori men (in two different cohorts of 8 and 24). All but one in the first cohort completed the programme. The first cohort had a modest although statistically insignificant improvement in weight loss (d = 1.04) and body mass index (BMI; d = 1.08). The second cohort had a significant reduction in weight loss (d = 1.16) and BMI (d = 1.15). They also had a significant increase in health-related quality of life (d = 1.7) and self-rated health (d = 2.0).

Conclusion

The HPW Framework appears to be well suited to advance implementation science for Indigenous communities in general and Māori in particular. The framework has promise as a policy and planning tool to evaluate and design interventions for chronic disease prevention in Indigenous communities. Despite this promise, there are structural challenges in developing and implementing interventions to address health inequities.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Testing the effects of interventions to increase consumption of fruit and vegetables, including those focused on specific child-feeding strategies or broader multicomponent interventions targeting the home or childcare environment is required to assess the potential to reduce this disease burden.

OBJECTIVES

To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and two clinical trials registries to identify eligible trials on 25 January 2020. We searched Proquest Dissertations and Theses in November 2019. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included trials to identify further potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risks of bias of included trials; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included 80 trials with 218 trial arms and 12,965 participants. Fifty trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fifteen trials examined the impact of parent nutrition education only in increasing child fruit and vegetable intake. Fourteen trials examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. Two trials examined the effect of a nutrition education intervention delivered to children in increasing child fruit and vegetable intake. One trial examined the impact of a child-focused mindfulness intervention in increasing vegetable intake. We judged 23 of the 80 included trials as free from high risks of bias across all domains. Performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining trials. There is low-quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption, equivalent to an increase of 5.30 grams as-desired consumption of vegetables (SMD 0.50, 95% CI 0.29 to 0.71; 19 trials, 2140 participants; mean post-intervention follow-up = 8.3 weeks). Multicomponent interventions versus no intervention has a small effect on child consumption of fruit and vegetables (SMD 0.32, 95% CI 0.09 to 0.55; 9 trials, 2961 participants; moderate-quality evidence; mean post-intervention follow-up = 5.4 weeks), equivalent to an increase of 0.34 cups of fruit and vegetables a day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.13, 95% CI -0.02 to 0.28; 11 trials, 3050 participants; very low-quality evidence; mean post-intervention follow-up = 13.2 weeks). We were unable to pool child nutrition education interventions in meta-analysis; both trials reported a positive intervention effect on child consumption of fruit and vegetables (low-quality evidence). Very few trials reported long-term effectiveness (6 trials), cost effectiveness (1 trial) or unintended adverse consequences of interventions (2 trials), limiting our ability to assess these outcomes. Trials reported receiving governmental or charitable funds, except for four trials reporting industry funding.

AUTHORS' CONCLUSIONS

Despite identifying 80 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains limited in terms of quality of evidence and magnitude of effect. Of the types of interventions identified, there was moderate-quality evidence that multicomponent interventions probably lead to, and low-quality evidence that child-feeding practice may lead to, only small increases in fruit and vegetable consumption in children aged five years and under. It is uncertain whether parent nutrition education or child nutrition education interventions alone are effective in increasing fruit and vegetable consumption in children aged five years and under. Our confidence in effect estimates for all intervention approaches, with the exception of multicomponent interventions, is limited on the basis of the very low to low-quality evidence. Long-term follow-up of at least 12 months is required and future research should adopt more rigorous methods to advance the field. This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available.

MAIN RESULTS

We included 78 trials with 214 trial arms and 13,746 participants. Forty-eight trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fifteen trials examined the impact of parent nutrition education in increasing child fruit and vegetable intake. Fourteen trials examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake.

Performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining trials. There is very low-quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption equivalent to an increase of 4.45 g as-desired consumption of vegetables (SMD 0.42, 95% CI 0.23 to 0.60; 18 trials, 2004 participants; mean post-intervention follow-up = 8.2 weeks). Multicomponent interventions versus no intervention has a small effect on child consumption of fruit and vegetables (SMD 0.34, 95% CI 0.10 to 0.57; 9 trials, 3022 participants; moderate-quality evidence; mean post-intervention follow-up = 5.4 weeks), equivalent to an increase of 0.36 cups of fruit and vegetables per day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.12, 95% CI -0.03 to 0.28; 11 trials, 3078 participants; very low-quality evidence; mean post-intervention follow-up = 13.2 weeks). We were unable to pool child nutrition education interventions in meta-analysis; both trials reported a positive intervention effect on child consumption of fruit and vegetables (low-quality evidence).

There was very low-quality evidence that child-feeding practice may lead to, and moderate-quality evidence that multicomponent interventions probably lead to small increases in fruit and vegetable consumption in children aged five years and younger. It is uncertain whether parent nutrition education interventions are effective in increasing fruit and vegetable consumption in children aged five years and younger. Given that the quality of the evidence is very low or low, future research will likely change estimates and conclusions. Long-term follow-up of at least 12 months is required and future research should adopt more rigorous methods to advance the field. This is a living systematic review.

Strengthening adolescents' connection to their traditional food system improves diet quality in remote Alaska Native communities: results from the Neqa Elicarvigmun Pilot Study

In remote Alaska Native communities, traditional foods are inextricably linked to health and food security. Degradation of the traditional food system over the past several decades has resulted in a shift in dietary patterns that have contributed to increased rates of chronic diseases and food insecurity among Alaska Native People. Interventions are needed to address this. Our objectives were to evaluate the preliminary efficacy of a school-based intervention-Neqa Elicarvigmun or the Fish-to-School Program-on diet quality, fish intake, and attitudes and beliefs around traditional foods (specifically fish) using a pre-post comparison group design with data collection occurring at three time points. Study participants were 76 middle and high school students in two remote Alaska Native communities (population <900) in southwestern Alaska. We used a participatory approach to design the school-based, multilevel intervention that included activities in the cafeteria, classroom, and community. Multilevel analyses showed that students in the experimental community showed significant improvements in diet quality compared to the comparison community (Beta = 4.57; p < .05). Fish intake, measured using the stable nitrogen isotope ratio of hair, a validated biomarker, also increased significantly in the experimental community (Beta = 0.16; p < .05). Leveraging the cultural and physical resources of the traditional food system for the Neqa Elicarvigmun program represents a strength-based approach that improves diet quality, increases adolescents' connection to their traditional culture, and by promoting the local food system supports food security. Embedding the program into the local culture may result in faster adoption and greater sustainability of the program.

How patient and community involvement in diabetes research influences health outcomes: A realist review

BACKGROUND

Patient and public involvement in diabetes research is an international requirement, but little is known about the relationship between the process of involvement and health outcomes.

OBJECTIVE

This realist review identifies who benefits from different types of involvement across different contexts and circumstances. Search strategies Medline, CINAHL and EMBASE were searched to identify interventions using targeted, embedded or collaborative involvement to reduce risk and promote self-management of diabetes. People at risk/with diabetes, providers and community organizations with an interest in addressing diabetes were included. There were no limitations on date, language or study type.

DATA EXTRACTION AND SYNTHESIS

Data were extracted from 29 projects using elements from involvement frameworks. A conceptual analysis of involvement types was used to complete the synthesis.

MAIN RESULTS

Projects used targeted (4), embedded (8) and collaborative (17) involvement. Productive interaction facilitated over a sufficient period of time enabled people to set priorities for research. Partnerships that committed to collaboration increased awareness of diabetes risk and mobilized people to co-design and co-deliver diabetes interventions. Cultural adaptation increased relevance and acceptance of the intervention because they trusted local delivery approaches. Local implementation produced high levels of recruitment and retention, which project teams associated with achieving diabetes health outcomes.

DISCUSSION AND CONCLUSIONS

Achieving understanding of community context, developing trusting relationships across sectors and developing productive partnerships were prerequisites for designing research that was feasible and locally relevant. The proportion of diabetes studies incorporating these elements is surprisingly low. Barriers to resourcing partnerships need to be systematically addressed.

Implementation effectiveness of health interventions for indigenous communities: a systematic review

BACKGROUND

Translating research into practice is an important issue for implementing health interventions effectively for Indigenous communities. He Pikinga Waiora (HPW) is a recent implementation framework that provides a strong foundation for designing and implementing health interventions in Indigenous communities for non-communicable diseases around community engagement, culture-centred approach, systems thinking and integrated knowledge translation. This study addresses the following research question: How are the elements of the HPW Implementation Framework reflected in studies involving the implementation of a non-communicable disease health intervention in an Indigenous community?

METHODS

A systematic review was conducted using multiple databases. Studies were included if they involved the implementation or evaluation of a health intervention targeting non-communicable diseases for Indigenous communities in Australia, Canada, New Zealand or the United States of America. Published quantitative and qualitative literature from 2008 to 2018 were included. Methodological appraisal of the included articles was completed using the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information. Data on the population, topic, methods, and outcomes were detailed for each individual study. Key data extracted included the HPW elements along with study characteristics, who delivered the intervention and health outcomes. Data analysis involved a qualitative synthesis of findings as guided by a coding scheme of the HPW elements.

RESULTS

Twenty-one studies were included. Health topics included diabetes, nutrition, weight loss, cancer and general health. The key themes were as follows: (a) two thirds of studies demonstrated high levels of community engagement; (b) from the culture-centred approach, two-thirds of studies reflected moderate to high levels of community voice/agency although only a third of the studies included structural changes and researcher reflexivity; (c) about a quarter of studies included multi-level outcomes and activities consistent with systems thinking, 40% had individual-level outcomes with some systems thinking, and 33% included individual-level outcomes and limited systems thinking; and (d) almost 40% of studies included high levels of end user (e.g., policy makers and tribal leaders) engagement reflective of integrated knowledge translation, but nearly half had limited end-user engagement.

CONCLUSIONS

The HPW Implementation Framework is a comprehensive model for potentially understanding implementation effectiveness in Indigenous communities. The review suggests that the studies are reflective of high levels of community engagement and culture-centredness. The long-term sustainability and translation of evidence to practice may be inhibited because of lower levels of systems thinking and integrated knowledge translation.

The Healthy Children, Strong Families 2 (HCSF2) Randomized Controlled Trial Improved Healthy Behaviors in American Indian Families with Young Children

BACKGROUND

American Indian (AI) families experience a disproportionate risk of obesity due to a number of complex reasons, including poverty, historic trauma, rural isolation or urban loss of community connections, lack of access to healthy foods and physical activity opportunities, and high stress. Home-based obesity prevention interventions are lacking for these families.

OBJECTIVE

Healthy Children, Strong Families 2 (HCSF2) was a randomized controlled trial of a healthy lifestyle promotion/obesity prevention intervention for AI families.

METHODS

Four hundred and fifty dyads consisting of an adult primary caregiver and a child ages 2 to 5 y from 5 AI communities were randomly assigned to a monthly mailed healthy lifestyle intervention toolkit (Wellness Journey) with social support or to a child safety control toolkit (Safety Journey) for 1 y. The Wellness Journey toolkit targeted increased fruit/vegetable (F/V) intake and physical activity, improved sleep, decreased added sugar intake and screen time, and improved stress management (adults only). Anthropometrics were collected, and health behaviors were assessed via survey at baseline and at the end of Year 1. Adults completed surveys for themselves and the participating child. Repeated measures analysis of variance was used to assess change over the intervention period.

RESULTS

Significant improvements to adult and child healthy diet patterns, adult F/V intake, adult moderate-to-vigorous physical activity, home nutrition environment, and adult self-efficacy for health behavior change were observed in Wellness Journey compared with Safety Journey families. No changes were observed in adult body mass index (BMI), child BMI z-score, adult stress measures, adult/child sleep and screen time, or child physical activity. Qualitative feedback suggests the intervention was extremely well-received by both the families and our community partners across the 5 participating sites.

CONCLUSIONS

This multi-site community-engaged intervention addressed key gaps regarding family home-based approaches for early obesity prevention in AI communities and showed several significant improvements in health behaviors. Multiple communities are working to sustain intervention efforts. This trial was registered at clinicaltrials.gov as NCT01776255.

Interventions for preventing obesity in children

EDITORIAL NOTE

This Cochrane review is now out of date and should not be used for reference. It has been split into four age groups and updated. Please refer to the 5‐11 and 12‐18 age group Cochrane reviews which were published in May 2024: https://doi.org/10.1002/14651858.CD015328.pub2 https://doi.org/10.1002/14651858.CD015330.pub2 The 2‐4 age group Cochrane review is planned for publication in September 2024.

BACKGROUND

Prevention of childhood obesity is an international public health priority given the significant impact of obesity on acute and chronic diseases, general health, development and well-being. The international evidence base for strategies to prevent obesity is very large and is accumulating rapidly. This is an update of a previous review.

OBJECTIVES

To determine the effectiveness of a range of interventions that include diet or physical activity components, or both, designed to prevent obesity in children.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, PsychINFO and CINAHL in June 2015. We re-ran the search from June 2015 to January 2018 and included a search of trial registers.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of diet or physical activity interventions, or combined diet and physical activity interventions, for preventing overweight or obesity in children (0-17 years) that reported outcomes at a minimum of 12 weeks from baseline.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data, assessed risk-of-bias and evaluated overall certainty of the evidence using GRADE. We extracted data on adiposity outcomes, sociodemographic characteristics, adverse events, intervention process and costs. We meta-analysed data as guided by the Cochrane Handbook for Systematic Reviews of Interventions and presented separate meta-analyses by age group for child 0 to 5 years, 6 to 12 years, and 13 to 18 years for zBMI and BMI.

MAIN RESULTS

We included 153 RCTs, mostly from the USA or Europe. Thirteen studies were based in upper-middle-income countries (UMIC: Brazil, Ecuador, Lebanon, Mexico, Thailand, Turkey, US-Mexico border), and one was based in a lower middle-income country (LMIC: Egypt). The majority (85) targeted children aged 6 to 12 years.Children aged 0-5 years: There is moderate-certainty evidence from 16 RCTs (n = 6261) that diet combined with physical activity interventions, compared with control, reduced BMI (mean difference (MD) -0.07 kg/m2, 95% confidence interval (CI) -0.14 to -0.01), and had a similar effect (11 RCTs, n = 5536) on zBMI (MD -0.11, 95% CI -0.21 to 0.01). Neither diet (moderate-certainty evidence) nor physical activity interventions alone (high-certainty evidence) compared with control reduced BMI (physical activity alone: MD -0.22 kg/m2, 95% CI -0.44 to 0.01) or zBMI (diet alone: MD -0.14, 95% CI -0.32 to 0.04; physical activity alone: MD 0.01, 95% CI -0.10 to 0.13) in children aged 0-5 years.Children aged 6 to 12 years: There is moderate-certainty evidence from 14 RCTs (n = 16,410) that physical activity interventions, compared with control, reduced BMI (MD -0.10 kg/m2, 95% CI -0.14 to -0.05). However, there is moderate-certainty evidence that they had little or no effect on zBMI (MD -0.02, 95% CI -0.06 to 0.02). There is low-certainty evidence from 20 RCTs (n = 24,043) that diet combined with physical activity interventions, compared with control, reduced zBMI (MD -0.05 kg/m2, 95% CI -0.10 to -0.01). There is high-certainty evidence that diet interventions, compared with control, had little impact on zBMI (MD -0.03, 95% CI -0.06 to 0.01) or BMI (-0.02 kg/m2, 95% CI -0.11 to 0.06).Children aged 13 to 18 years: There is very low-certainty evidence that physical activity interventions, compared with control reduced BMI (MD -1.53 kg/m2, 95% CI -2.67 to -0.39; 4 RCTs; n = 720); and low-certainty evidence for a reduction in zBMI (MD -0.2, 95% CI -0.3 to -0.1; 1 RCT; n = 100). There is low-certainty evidence from eight RCTs (n = 16,583) that diet combined with physical activity interventions, compared with control, had no effect on BMI (MD -0.02 kg/m2, 95% CI -0.10 to 0.05); or zBMI (MD 0.01, 95% CI -0.05 to 0.07; 6 RCTs; n = 16,543). Evidence from two RCTs (low-certainty evidence; n = 294) found no effect of diet interventions on BMI.Direct comparisons of interventions: Two RCTs reported data directly comparing diet with either physical activity or diet combined with physical activity interventions for children aged 6 to 12 years and reported no differences.Heterogeneity was apparent in the results from all three age groups, which could not be entirely explained by setting or duration of the interventions. Where reported, interventions did not appear to result in adverse effects (16 RCTs) or increase health inequalities (gender: 30 RCTs; socioeconomic status: 18 RCTs), although relatively few studies examined these factors.Re-running the searches in January 2018 identified 315 records with potential relevance to this review, which will be synthesised in the next update.

AUTHORS' CONCLUSIONS

Interventions that include diet combined with physical activity interventions can reduce the risk of obesity (zBMI and BMI) in young children aged 0 to 5 years. There is weaker evidence from a single study that dietary interventions may be beneficial.However, interventions that focus only on physical activity do not appear to be effective in children of this age. In contrast, interventions that only focus on physical activity can reduce the risk of obesity (BMI) in children aged 6 to 12 years, and adolescents aged 13 to 18 years. In these age groups, there is no evidence that interventions that only focus on diet are effective, and some evidence that diet combined with physical activity interventions may be effective. Importantly, this updated review also suggests that interventions to prevent childhood obesity do not appear to result in adverse effects or health inequalities.The review will not be updated in its current form. To manage the growth in RCTs of child obesity prevention interventions, in future, this review will be split into three separate reviews based on child age.

The Impact of a Healthy Weight Intervention Embedded in a Home-Visiting Program on Children's Weight and Mothers' Feeding Practices

OBJECTIVE

To examine whether a healthy weight intervention embedded in the Parents as Teachers (PAT) home visiting program, which was previously found to improve mothers' body mass index (BMI) and obesity-related behaviors, changed the BMI of preschool children or maternal feeding practices.

METHODS

This stratified randomized trial included preschool-aged children at risk for overweight whose mothers were overweight or had obesity (n = 179). The Healthy Eating and Active Living Taught at Home (HEALTH) intervention was based on the Diabetes Prevention Program. Differences were examined using repeated-measures mixed-ANOVA models.

RESULTS

Compared with PAT usual care, the HEALTH intervention had no effect on children's BMI or maternal feeding practices. However, combined analyses showed that children's BMI percentile decreased (P  = .007), BMI z-scores were maintained (P  = .19), and 3 of 8 feeding practices improved over time (P < .05).

CONCLUSIONS AND IMPLICATIONS

Additional research is needed to assess the effectiveness of PAT to prevent preschool-age obesity using rigorous designs (eg, group-randomized trials) and to identify its active components. HEALTH is ready to be scaled up to prevent maternal weight gain through embedding within the national PAT program.

Overnight sleep duration and obesity in 2-5 year-old American Indian children

BACKGROUND

Sleep has emerged as a potentially modifiable risk factor for obesity in children.

OBJECTIVES

The purpose of this investigation was to evaluate the association between overnight sleep duration and obesity among American Indian (AI) children ages 2-5 years.

METHODS

Data were examined from the baseline assessment of children enrolling in the Healthy Children, Strong Families study, which is a randomized lifestyle intervention trial in five diverse rural and urban AI communities nationally among children ages 2-5 years. Multivariable models were built to assess the relationship between sleep duration and BMI z-score while controlling for potential sociodemographic and behavioural covariates.

RESULTS

Three hundred and ninety-eight children had sufficient data to be included in analysis. In multivariable models controlling for potential covariates, overnight sleep duration was significantly and inversely associated with BMI z-score (B = -0.158, t = -1.774, P = 0.006). Similarly, when controlling for covariates, children who slept 12 or more hours had significantly lower BMI z-scores compared with those who slept 8 to 10 h (P = 0.018) or less than 8 h (P = 0.035); the difference between 12+ hours and 10 to 12-h groups did not reach statistical significance (P = 0.073) but supported a linear relationship between overnight sleep duration and BMI. Weekday-to-weekend variability in overnight sleep duration was not associated with BMI z-score (B = 0.010, t = 0.206, P = 0.837).

CONCLUSIONS

Overnight sleep duration is independently and inversely related to BMI z-score among AI children ages 2-5 years, even when controlling for important sociodemographic and obesogenic lifestyle factors. This represents the first report, to our knowledge, of sleep duration as a risk factor for obesity among AI children.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future non-communicable diseases, including cardiovascular disease. Interventions to increase consumption of fruit and vegetables, such as those focused on specific child-feeding strategies and parent nutrition education interventions in early childhood may therefore be an effective strategy in reducing this disease burden.

OBJECTIVES

To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and two clinical trials registries to identify eligible trials on 25 January 2018. We searched Proquest Dissertations and Theses in November 2017. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included studies to identify further potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risks of bias of included studies; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included 63 trials with 178 trial arms and 11,698 participants. Thirty-nine trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Fourteen trials examined the impact of parent nutrition education in increasing child fruit and vegetable intake. Nine studies examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. One study examined the effect of a nutrition education intervention delivered to children in increasing child fruit and vegetable intake.We judged 14 of the 63 included trials as free from high risks of bias across all domains; performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining studies.There is very low quality evidence that child-feeding practices versus no intervention may have a small positive effect on child vegetable consumption equivalent to an increase of 3.50 g as-desired consumption of vegetables (SMD 0.33, 95% CI 0.13 to 0.54; participants = 1741; studies = 13). Multicomponent interventions versus no intervention may have a very small effect on child consumption of fruit and vegetables (SMD 0.35, 95% CI 0.04 to 0.66; participants = 2009; studies = 5; low-quality evidence), equivalent to an increase of 0.37 cups of fruit and vegetables per day. It is uncertain whether there are any short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.12, 95% CI -0.03 to 0.28; participants = 3078; studies = 11; very low-quality evidence).Insufficient data were available to assess long-term effectiveness, cost effectiveness and unintended adverse consequences of interventions. Studies reported receiving governmental or charitable funds, except for four studies reporting industry funding.

AUTHORS' CONCLUSIONS

Despite identifying 63 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains limited. There was very low- and low-quality evidence respectively that child-feeding practice and multicomponent interventions may lead to very small increases in fruit and vegetable consumption in children aged five years and younger. It is uncertain whether parent nutrition education interventions are effective in increasing fruit and vegetable consumption in children aged five years and younger. Given that the quality of the evidence is very low or low, future research will likely change estimates and conclusions. Long-term follow-up is required and future research should adopt more rigorous methods to advance the field.This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available.

Development of a Culturally Informed Child Safety Curriculum for American Indian Families

American Indian (AI) children are disproportionately affected by unintentional injuries, with injury mortality rates approximately 2.3 times higher than the combined rates for all children in the United States. Although multiple risk factors are known to contribute to these increased rates, a comprehensive, culturally informed curriculum that emphasizes child safety is lacking for this population. In response to this need, academic and tribal researchers, tribal community members, tribal wellness staff, and national child safety experts collaborated to develop a novel child safety curriculum. This paper describes its development and community delivery. We developed the safety curriculum as part of a larger randomized controlled trial known as Healthy Children, Strong Families 2 (HCSF2), a family-based intervention targeting obesity prevention in early childhood (2-5 years). During the development of the HCSF2 intervention, participating tribal communities expressed concern about randomizing enrolled families to a control group who would not receive an intervention. To address this concern and the significant disparities in injuries and unintentional death rates among AI children, we added an active control group (Safety Journey) that would utilize our safety curriculum. Satisfaction surveys administered at the 12-month time point of the intervention indicate 94% of participants (N = 196) were either satisfied or very satisfied with the child safety curriculum. The majority of participants (69%) reported spending more than 15 min with the curriculum materials each month, and 83% thought the child safety newsletters were either helpful or very helpful in making changes to improve their family's safety. These findings indicate these child safety materials have been well received by HCSF2 participants. The use of community-engaged approaches to develop this curriculum represents a model that could be adapted for other at-risk populations and serves as an initial step toward the creation of a multi-level child safety intervention strategy.

Interventions for increasing fruit and vegetable consumption in children aged five years and under

BACKGROUND

Insufficient consumption of fruits and vegetables in childhood increases the risk of future chronic diseases, including cardiovascular disease.

OBJECTIVES

To assess the effectiveness, cost effectiveness and associated adverse events of interventions designed to increase the consumption of fruit, vegetables or both amongst children aged five years and under.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE and Embase to identify eligible trials on 25 September 2017. We searched Proquest Dissertations and Theses and two clinical trial registers in November 2017. We reviewed reference lists of included trials and handsearched three international nutrition journals. We contacted authors of included studies to identify further potentially relevant trials.

SELECTION CRITERIA

We included randomised controlled trials, including cluster-randomised controlled trials and cross-over trials, of any intervention primarily targeting consumption of fruit, vegetables or both among children aged five years and under, and incorporating a dietary or biochemical assessment of fruit or vegetable consumption. Two review authors independently screened titles and abstracts of identified papers; a third review author resolved disagreements.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and assessed the risks of bias of included studies; a third review author resolved disagreements. Due to unexplained heterogeneity, we used random-effects models in meta-analyses for the primary review outcomes where we identified sufficient trials. We calculated standardised mean differences (SMDs) to account for the heterogeneity of fruit and vegetable consumption measures. We conducted assessments of risks of bias and evaluated the quality of evidence (GRADE approach) using Cochrane procedures.

MAIN RESULTS

We included 55 trials with 154 trial arms and 11,108 participants. Thirty-three trials examined the impact of child-feeding practices (e.g. repeated food exposure) in increasing child vegetable intake. Thirteen trials examined the impact of parent nutrition education in increasing child fruit and vegetable intake. Eight studies examined the impact of multicomponent interventions (e.g. parent nutrition education and preschool policy changes) in increasing child fruit and vegetable intake. One study examined the effect of a nutrition intervention delivered to children in increasing child fruit and vegetable intake.We judged 14 of the 55 included trials as free from high risks of bias across all domains; performance, detection and attrition bias were the most common domains judged at high risk of bias for the remaining studies.Meta-analysis of trials examining child-feeding practices versus no intervention revealed a positive effect on child vegetable consumption (SMD 0.38, 95% confidence interval (CI) 0.15 to 0.61; n = 1509; 11 studies; very low-quality evidence), equivalent to a mean difference of 4.03 g of vegetables. There were no short-term differences in child consumption of fruit and vegetables in meta-analyses of trials examining parent nutrition education versus no intervention (SMD 0.11, 95% CI -0.05 to 0.28; n = 3023; 10 studies; very low-quality evidence) or multicomponent interventions versus no intervention (SMD 0.28, 95% CI -0.06 to 0.63; n = 1861; 4 studies; very low-quality evidence).Insufficient data were available to assess long-term effectiveness, cost effectiveness and unintended adverse consequences of interventions. Studies reported receiving governmental or charitable funds, except for three studies reporting industry funding.

AUTHORS' CONCLUSIONS

Despite identifying 55 eligible trials of various intervention approaches, the evidence for how to increase children's fruit and vegetable consumption remains sparse. There was very low-quality evidence that child-feeding practice interventions are effective in increasing vegetable consumption in children aged five years and younger, however the effect size was very small and long-term follow-up is required. There was very low-quality evidence that parent nutrition education and multicomponent interventions are not effective in increasing fruit and vegetable consumption in children aged five years and younger. All findings should be considered with caution, given most included trials could not be combined in meta-analyses. Given the very low-quality evidence, future research will very likely change estimates and conclusions. Such research should adopt more rigorous methods to advance the field.This is a living systematic review.

Assessing and Communicating the Value of Biomedical Research: Results From a Pilot Study

PURPOSE

Assessing the impact of research requires an approach that is sensitive both to the context of the research and the perspective of the stakeholders trying to understand its benefits. Here, the authors report on a pilot that applied such an approach to research conducted at the Collaborative Center for Health Equity (CCHE) of the University of Wisconsin School of Medicine and Public Health.

METHOD

The pilot assessed the academic impact of CCHE's work; the networks between CCHE and community partners; and the reach of CCHE's programs, including an attempt to estimate return on investment (ROI). Data included bibliometrics, findings from a stakeholder survey and in-depth interviews, and financial figures.

RESULTS

The pilot illustrated how CCHE programs increase the capacity of community partners to advocate for their communities and engage with researchers to ensure that research benefits the community. The results illustrate the reach of CCHE's programs into the community. The authors produced an estimate of the ROI for one CCHE program targeting childhood obesity, and values ranged from negative to positive.

CONCLUSIONS

The authors experienced challenges using novel assessment techniques at a small scale including the lack of comparator groups and the scarcity of cost data for estimating ROI. This pilot demonstrated the value of research from a variety of perspectives-from academic to community. It illustrates how metrics beyond grant income and publications can capture the outputs of an academic health center in a way that may better align with the aims of the center and stakeholders.

Household food insecurity and dietary patterns in rural and urban American Indian families with young children

BACKGROUND

High food insecurity has been demonstrated in rural American Indian households, but little is known about American Indian families in urban settings or the association of food insecurity with diet for these families. The purpose of this study was to examine the prevalence of food insecurity in American Indian households by urban-rural status, correlates of food insecurity in these households, and the relationship between food insecurity and diet in these households.

METHODS

Dyads consisting of an adult caregiver and a child (2-5 years old) from the same household in five urban and rural American Indian communities were included. Demographic information was collected, and food insecurity was assessed using two validated items from the USDA Household Food Security Survey. Factors associated with food insecurity were examined using logistic regression. Child and adult diets were assessed using food screeners. Coping strategies were assessed through focus group discussions. These cross-sectional baseline data were collected from 2/2013 through 4/2015 for the Healthy Children, Strong Families 2 randomized controlled trial of a healthy lifestyles intervention for American Indian families.

RESULTS

A high prevalence of food insecurity was determined (61%) and was associated with American Indian ethnicity, lower educational level, single adult households, WIC participation, and urban settings (p = 0.05). Food insecure adults had significantly lower intake of vegetables (p < 0.05) and higher intakes of fruit juice (<0.001), other sugar-sweetened beverages (p < 0.05), and fried potatoes (p < 0.001) than food secure adults. Food insecure children had significantly higher intakes of fried potatoes (p < 0.05), soda (p = 0.01), and sports drinks (p < 0.05). Focus group participants indicated different strategies were used by urban and rural households to address food insecurity.

CONCLUSIONS

The prevalence of food insecurity in American Indian households in our sample is extremely high, and geographic designation may be an important contributing factor. Moreover, food insecurity had a significant negative influence on dietary intake for families. Understanding strategies employed by households may help inform future interventions to address food insecurity.
