Barriers and facilitators of childhood obesity prevention policies: A systematic review and meta-synthesis

Objectives

Childhood obesity is one of the worldwide considerable public health challenges and many factors can play a role in its management. Therefore, this article examined the facilitators and barriers of childhood obesity prevention (COP) policies.

Methods

This systematic review of qualitative studies was conducted via a search of the SCOPUS, PubMed, and Google Scholar databases between 1 January 2010 and 11 February 2022 and examined factors that influence the implementation of COP policies at a community approach.

Results

The parents' reluctance to engage in COP activities, lack of sufficient knowledge, and financial problems were the most reported barriers at the individual level. In addition, the beliefs about COP at the sociocultural level and limited funding and resources, time limitations in stakeholders at the implementation level, and lack of policy support at the structural level were the most frequently reported barriers. Further, effective communication between stakeholders and parents and school staff at the sociocultural level and flexibility of the intervention, delivery of healthy food programs in schools, low-cost and appropriate resources, and the availability of appropriate facilities are the most frequently reported facilitators in the structural level.

Conclusion

Individual, sociocultural, and structural level-related barriers and facilitators influence the implementation of COP policies. Most of the barriers and facilitators in this systematic review were related to the structural level.

Stakeholders perspectives of barriers and facilitators of childhood obesity prevention policies in Iran: A Delphi method study

Background

The prevalence of obesity among children and adolescents is one of the most important health challenges of the present century. Many factors affect the prevention policies related to this health problem and make their implementation difficult. This study examined perceived barriers and facilitators of childhood obesity prevention policies by stakeholders.

Methods

A qualitative descriptive research design based on Delphi method was conducted. In addition, semi-structured one-to-one interviews were conducted with childhood obesity prevention policy stakeholders (n=39) and initial identification of barriers and facilitators in this area. Interviews were digitally recorded, transcribed verbatim, and finally analyzed, followed by using thematic analysis. Subsequently, two-round Delphi panel was done by sending e-mails to stakeholders (21 stakeholders participated in the first round and 15 stakeholders in the second round) for the final selection of barriers and facilitators of obesity prevention policies among children and adolescents in Iran.

Results

The identified barriers and facilitators were divided into three levels: individual, executive, and structural. Barriers and facilitators of the structural level showed a high score and priority regarding obesity prevention policies among children and adolescents.

Conclusion

The existence of significant barriers at all three levels and especially at the structural level were among the concerns of stakeholders.

[Entorno social y obesidad infantil: implicaciones para la investigación y la práctica en Estados Unidos y en los países latinoamericanos]

The environments of children influence their risk for childhood obesity through, among other factors, a child's weight-related behaviors (i.e., diet and physical activity). In this article, we present evidence on social environmental factors associated with a child's diet and physical activity, and more generally, the prevention and control of childhood obesity among Hispanic/Latinx children in the United States and children from countries in Latin America. Using a socio-ecologic lens, we present evidence from cross-sectional and longitudinal studies conducted in the United States involving Hispanic/Latinx children, and evidence from studies involving children in Latin America. Studies examining parenting factors in the home environment (e.g., parenting strategies) are especially emphasized, with more limited evidence on social environmental factors in other lived contexts (e.g., school). The influence of acculturation on social relationships cuts across levels of the socio-ecological framework. Intervention research identified strategies and research gaps for intervening on social factors to promote healthy behaviors and reduce risk for childhood obesity. Community health workers and others forms of peer support were identified as relevant approaches at multiple levels of the socio-ecological framework. This article concludes with directions for future research to further understand the environment using newer information and communication technologies.

Children's perceptions of their parent's parenting strategies and child influence on purchases in a supermarket

This field study identified, through observation, child influence on food and beverage purchases within a supermarket, as well as the influence of the children's perceptions of their parents' parenting strategies related to eating behaviors on these purchases. Four supermarkets were recruited to participate and agreed to allow recruitment of parent-child dyads and implementation of data collection protocols within their stores. Parent-child (7-14 yo) dyads were recruited to wear eye-tracking glasses during the supermarket visit, complete separate individual interviews, and have their store receipts scanned. The receipt data provided evidence of what was purchased, including overall purchases, as well as purchases of energy-dense, nutrient-poor foods and beverages. The eye-tracking data, together with the receipt data, identified which items were requested by the child and purchased. The child interviews provided the child's perceptions of parenting strategies (i.e., parental monitoring, control). Seventy-six dyads agreed to participate and completed the study protocols. During most of the shopping trips, items were purchased as a result of child-initiated request interactions. Children's perceptions of their parent's use of monitoring was consistently associated with fewer purchases overall and of energy-dense, nutrient-poor items, and with reduced child influence on what was purchased.

Cross-Site Process Evaluation Results for the Early Childhood Education Center Setting: CORD Study

Background: The Childhood Obesity Research Demonstration project aimed to deliver evidence-based obesity prevention interventions to at-risk families at three demonstration sites. The interventions were delivered in multiple settings, including early childhood education centers (ECECs), public schools, and primary care clinics. An evaluation center conducted cross-site process, impact, and sustainability evaluations. Results of the cross-site process evaluation for the ECECs will be described. Methods: Reach (proportion of the target population who participated), dose delivered (materials and interventions that were distributed), and fidelity (proportion of planned intervention components delivered) were assessed at two levels (researcher-to-provider and provider-to-family levels). Standardized data forms were completed by research team members at each demonstration site with assistance from the evaluation center. Results: The Childhood Obesity Research Demonstration project reached 5174 children and 390 teachers in 58 ECECs. The centers delivered an average of 3.9 hours of training to teachers. A total of 1382 different types of materials were distributed to providers, and from 1.3 to 4.3 hours of technical support were delivered to centers monthly. For fidelity at the researcher-to-provider level, 49.5% (n = 370) of eligible teachers completed all training sessions. Considerable variations across demonstration sites in reach, dose delivered, and fidelity across were observed. Conclusion: The Childhood Obesity Research Demonstration project reached large numbers of children, families, teachers, and ECECs. Maintaining intervention fidelity while reaching large numbers of at-risk individuals proved to be a challenge.

Prevention and Management of Childhood Obesity and Its Psychological and Health Comorbidities

Childhood obesity has become a global pandemic in developed countries, leading to a host of medical conditions that contribute to increased morbidity and premature death. The causes of obesity in childhood and adolescence are complex and multifaceted, presenting researchers and clinicians with myriad challenges in preventing and managing the problem. This article reviews the state of the science for understanding the etiology of childhood obesity, the preventive interventions and treatment options for overweight and obesity, and the medical complications and co-occurring psychological conditions that result from excess adiposity, such as hypertension, nonalcoholic fatty liver disease, and depression. Interventions across the developmental span, varying risk levels, and service contexts (e.g.,community, school, home, health care systems) are reviewed. Future directions for research are offered with an emphasis on translational issues for taking evidence-based interventions to scale in a manner that will reduce the public health burden of the childhood obesity pandemic.

Process Evaluation and Lessons Learned From Engaging Local Policymakers in the B'More Healthy Communities for Kids Trial

Partnerships linking researchers to the policymaking process can be effective in increasing communication and supporting health policy. However, these policy partnerships rarely conduct process evaluation. The Policy Working Group (Policy WG) was the policy-level intervention of the multilevel B'More Healthy Communities for Kids (BHCK) trial. The group sought to align interests of local policymakers, inform local food and nutrition policy, introduce policymakers to a new simulation modeling, and sustain intervention levels of BHCK. We conducted an evaluation on the Policy WG between July 2013 and May 2016. We evaluated process indicators for reach, dose-delivered, and fidelity and developed a SWOT (strengths, weaknesses, opportunities, and threats) analysis. The policy intervention was implemented with high reach and dose-delivered. Fidelity measures improved from moderate to nearly high over time. The number of health-related issues on policymakers' agenda increased from 50% in the first 2 years to 150% of the high standard in Year 3. SWOT analysis integrated a stakeholder feedback survey to consider areas of strength, weakness, opportunity, and threats. Although the fidelity of the modeling was low at 37% of the high standard, stakeholders indicated that the simulation modeling should be a primary purpose for policy intervention. Results demonstrate that process evaluation and SWOT analysis is useful for tracking the progress of policy interventions in multilevel trials and can be used to monitor the progress of building partnerships with policymakers.

Implementation of B'More Healthy Communities for Kids: process evaluation of a multi-level, multi-component obesity prevention intervention

B'More Healthy Communities for Kids was a multi-level, multi-component obesity prevention intervention to improve access, demand and consumption of healthier foods and beverages in 28 low-income neighborhoods in Baltimore City, MD. Process evaluation assesses the implementation of an intervention and monitor progress. To the best of our knowledge, little detailed process data from multi-level obesity prevention trials have been published. Implementation of each intervention component (wholesaler, recreation center, carryout restaurant, corner store, policy and social media/text messaging) was classified as high, medium or low according to set standards. The wholesaler component achieved high implementation for reach, dose delivered and fidelity. Recreation center and carryout restaurant components achieved medium reach, dose delivered and fidelity. Corner stores achieved medium reach and dose delivered and high fidelity. The policy component achieved high reach and medium dose delivered and fidelity. Social media/text messaging achieved medium reach and high dose delivered and fidelity. Overall, study reach and dose delivered achieved a high implementation level, whereas fidelity achieved a medium level. Varying levels of implementation may have balanced the performance of an intervention component for each process evaluation construct. This detailed process evaluation of the B'More Healthy Communities for Kids allowed the assessment of implementation successes, failures and challenges of each intervention component.

Understanding paediatric patients' attitudes toward obesity and expectations prior to entering a weight management program

Objective

This qualitative study explored attitudes toward weight management and knowledge of healthy, active living among paediatric patients referred to a weight management program. The objective of this study was to determine the emotional state and attitudes of patients entering into a paediatric weight management program.

Methods

Study participants (aged 7 to 17 years old) were recruited during clinic orientation. Semistructured interviews were conducted, audiotaped and transcribed verbatim. Qualitative content analysis generated a thematic coding scheme, identifying concepts and linkages in the data. Study rigour was achieved collaboratively through an audit trail, and data triangulation.

Results

Fifteen patients (median age 11 years) consented to interviews. Three recurring themes emerged: emotions, motivation and learning. A total of nine subthemes were identified. Four key spheres of influence (family, peers, school and health care providers) affected the patient's outlook on obesity positively by providing support or negatively by adversely influencing their emotions and motivation. The level of individual motivation to engage in the weight management program varied. A positive outlook toward learning about obesity from school officials and health care providers emerged.

Conclusions

This study provided insight regarding paediatric attitudes related to entering a weight management program. The negative emotional state and sometimes fear of the program expressed should be considered by the referring physician and by clinicians in weight management programs engaging in their care.
