Effectiveness and safety of interventions to manage childhood overweight and obesity: An Overview of Cochrane systematic reviews

A Proposed Pediatric Clinical Cardiovascular Health Reference Standard

INTRODUCTION

Clinical cardiovascular health is a construct that includes 4 health factors-systolic and diastolic blood pressure, fasting glucose, total cholesterol, and body mass index-which together provide an evidence-based, more holistic view of cardiovascular health risk in adults than each component separately. Currently, no pediatric version of this construct exists. This study sought to develop sex-specific charts of clinical cardiovascular health for age to describe current patterns of clinical cardiovascular health throughout childhood.

METHODS

Data were used from children and adolescents aged 8-19 years in six pooled childhood cohorts (19,261 participants, collected between 1972 and 2010) to create reference standards for fasting glucose and total cholesterol. Using the models for glucose and cholesterol as well as previously published reference standards for body mass index and blood pressure, clinical cardiovascular health charts were developed. All models were estimated using sex-specific random-effects linear regression, and modeling was performed during 2020-2022.

RESULTS

Models were created to generate charts with smoothed means, percentiles, and standard deviations of clinical cardiovascular health for each year of childhood. For example, a 10-year-old girl with a body mass index of 16 kg/m2 (30th percentile), blood pressure of 100/60 mm Hg (46th/50th), glucose of 80 mg/dL (31st), and total cholesterol of 160 mg/dL (46th) (lower implies better) would have a clinical cardiovascular health percentile of 62 (higher implies better).

CONCLUSIONS

Clinical cardiovascular health charts based on pediatric data offer a standardized approach to express clinical cardiovascular health as an age- and sex-standardized percentile for clinicians to assess cardiovascular health in childhood to consider preventive approaches at early ages and proactively optimize lifetime trajectories of cardiovascular health.

Four year evaluation of a parent advisory group to support a research program for knowledge translation in child health

BACKGROUND

In 2016, we developed a pediatric parent advisory group to inform our research program which creates innovative knowledge translation (KT) tools for parents on priority topics related to acute childhood illness. We implemented a mixed methods strategy to evaluate the experiences of group members. The purpose of this paper is to present the findings from parent evaluations over four years and to discuss our experiences collaborating with the group over a multi-year period.

METHODS

We conducted year-end surveys and interviews of group members to understand parents' perceptions of their experiences, group management, researcher interaction, and other outcomes of advisory group participation from 2018 to 2021. We applied a mixed methods approach, collecting and analyzing both quantitative (survey) and qualitative (survey/interview) data. Survey data were analyzed by term using descriptive statistics (i.e., frequencies, percentages). Open-ended survey responses were analyzed by conventional content analysis. Interview data were analysed thematically.

RESULTS

Year-end survey response rates and interview participation varied over the years. Responses to evaluation questions were generally positive and most improved over time. Results prompted changes to improve P-PAG operations, such as changes to location of meetings, communications about the group's purpose, offering sufficient context for discussion items, and providing feedback about how members' input was used. Themes identified from the qualitative data related to the importance of certain aspects of group functioning, positive views of the group's current management, and potential areas for improvement. Parents regularly expressed a desire for more diversity in the group's membership and an interest in hearing more about how the research program's activities fit into the broader healthcare system and their impacts on health outcomes.

CONCLUSIONS

Our experience in establishing, managing, and evaluating a parent advisory group over many years has resulted in valuable insights regarding patient engagement in health research and sustaining an advisory group over time. We have learned that an intentional and iterative approach with regular evaluations and responsive changes has been essential for fostering meaningful engagement. Significant resources are required to maintain the group; in turn, the group has made substantial and diverse contributions to the research program and its outputs.

Comparison of a Telehealth-Based Intensive Treatment Program with a Rewarding App vs. On-Site Care for Youth with Obesity: A Historical Cohort Study

The recommended treatment for children with obesity includes numerous consultations by a multidisciplinary team, which is very cumbersome. Telehealth can assist in administering frequent care to children with obesity, yet the exact approaches and modes of delivery are still explored. During the COVID-19 pandemic, we developed an intensive telehealth-based treatment program that included a rewarding app for children with obesity. The aim of this study was to compare 6-month changes in body mass index (BMI) and body fat percent between participants in the program (n = 70) vs. children that underwent historic on-site care (n = 87). After 6 months, more participants in the telehealth group continued treatment compared to the on-site group (79% vs. 60%, p < 0.001). A significant reduction in the median BMI z-score (zBMI) was seen after 6 months in both groups (p < 0.01), with a similar proportion of zBMI reductions (71% in the telehealth group, 75% in the comparison group, p = 0.76). No statistically significant differences were found between the study groups in 6-month changes in BMI, zBMI, body fat percent or fat z-scores. We conclude that our telehealth program, which was executed during the COVID-19 pandemic, resulted in a high proportion of children with zBMI reduction that was comparable with the more personal on-site care.
