Background: This study aimed to assess the implementation and access to telehealth-delivered pediatric weight management (PWM) during the initial phase of the COVID-19 pandemic at six US PWM programs (PWMP) using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. Methods: The COVID-19 period (COVID) was defined in this retrospective, multisite study as the time when each site closed in-person care during 2020. The Pre-COVID period (Pre-COVID) was an equivalent time frame in 2019. Patients were stratified by visit completion status. Patient characteristics for COVID and Pre-COVID were compared to examine potential changes/disparities in access to care. Results: There were 3297 unique patients included across the six sites. On average, telehealth was initiated 4 days after in-person clinic closure. Compared with Pre-COVID, COVID (mean duration: 9 weeks) yielded fewer total completed visits (1300 vs. 2157) and decreased revenue (mean proportion of nonreimbursed visits 33.30% vs. 16.67%). Among the completed visits, COVID included a lower proportion of new visits and fewer patients who were male, non-English speaking, Hispanic, or Asian and more patients who were Black or lived ≥20 miles from the program site (p < 0.05 for all). Among no-show/canceled visits, COVID included more patients who had private insurance, older age, or a longer time since the last follow-up. Conclusion: Rapid implementation of telehealth during COVID facilitated continuity of PWM care. Clinic volume and reimbursement were lower during COVID and differences in the patient population reached by telehealth emerged. Further characterization of barriers to telehealth for PWM is needed.

Objective: The aim of this study was to examine associations of childhood physical activity, sedentary behavior, and dietary intake with adiposity trajectories from childhood to adolescence. Methods: Quebec Adipose and Lifestyle Investigation in Youth (QUALITY) cohort (n = 630) data from 3 time points (8-10, 10-12, and 15-17 years) for 377 Caucasian children with parental obesity were analyzed. Height and weight, physical activity and sedentary behavior (7-day accelerometry), screen time (self-reported), and dietary intake (three 24-hour diet recalls) were measured. Group-based trajectory modeling identified longitudinal trajectories of body-mass index z-scores (zBMIs). Inverse probability of exposure-weighted multinomial logistic regressions examined associations between baseline lifestyles and zBMI trajectory groups. Results: Six trajectory groups were identified: Stable-Low-Normal-Weight (two groups, 5.7% and 33.0%, which were combined), Stable-High-Normal-Weight (24.8%), Stable-Overweight (19.8%), Stable-Obesity (8.8%), and Overweight-Decreasers (7.9%). For every additional portion of fruits and vegetables, the likelihood of being in the group of Overweight-Decreasers increased by 29% (odds ratio [OR]: 1.29, 95% confidence interval [CI]: 1.09-1.55) compared with the reference group (Stable-Low-Normal-Weight). For every additional hour of sedentary behavior, the likelihood of belonging to the group of Overweight-Decreasers increased 2-fold (OR: 1.99, 95% CI: 1.28-3.21) and Stable-Obesity increased 1.5-fold (OR: 1.56, 95% CI: 1.08-2.23), compared with the reference. Every additional 10 minutes of moderate-to-vigorous physical activity was associated with a lower likelihood of belonging to the Stable-Obesity group (OR: 0.75, 95% CI: 0.61-0.89) and to the group of Overweight-Decreasers (OR: 0.79, 95% CI: 0.64-0.95) compared with the reference. Finally, children were more likely to belong to the Stable-Obesity group with each additional hour/day of screen time (OR: 1.23, 95% CI: 1.01-1.58). Conclusions: Trajectories of zBMIs from childhood to late adolescence were stable, except for one group which decreased from overweight in childhood to normal weight in adolescence. The latter had more favorable baseline dietary intake of fruits and vegetables. ClinicalTrials.org no. NCT03356262.

Background: A bidirectional association between shape and weight concerns (SWC) and physical activity (PA) has been previously documented. This relationship may be particularly salient among youth with overweight/obesity, given that social marginalization of larger bodies has been associated with elevated SWC and barriers to PA. This pilot study explores reciprocal relationships between momentary SWC and accelerometer-assessed PA behavior. Methods: Youth with overweight/obesity (N = 17) participated in a 14-day ecological momentary assessment protocol, during which they were prompted to respond to questions about SWC several times per day. They also continuously wore Actiwatch 2 accelerometers to capture light and moderate-to-vigorous PA behavior. Results: Hierarchical linear modeling revealed a unidirectional association between SWC and PA, whereby after engaging in a higher duration of PA, participants reported lower SWC. SWC did not predict subsequent PA. Conclusion: The findings support a negative temporal relationship between PA and SWC. While further work is needed to replicate and extend these preliminary findings, they may suggest that PA acutely benefits SWC among youth with overweight and obesity.

Background: Childhood obesity (CO) is rapidly increasing in prevalence and developing into a health crisis of developed nations. The condition is associated with increased risk of developing various comorbidities later in life. Current treatment algorithms primarily target family education. Thus, this study aims to understand the quality of information online regarding CO and common comorbidities, determine the readability of online information, and report patterns in public interest over time using Google Trends. Methods: Four validated quality of information tools and 6 readability tools were implemented across 36 websites derived from 4 Google searches. Pearson's correlation coefficient was used to determine the associations between Google Trends' relative search volumes (RSVs) and biennial BMI-based cumulative proportion of CO. Results: Results showed variable information quality among the websites as scores ranged from "fair" to "very poor." Using six readability formulas, no website scored at or below the sixth grade reading level recommended by the American Medical Association. Google Trends' RSVs for the term "Childhood Obesity" were repeatedly increased in the months that fall in the US academic school year (October-November and February-May), and decreased within months in the US vacation periods (December-January and June-September). Search volumes were also negatively correlated with CO and pediatric type 2 diabetes prevalence. Conclusions: In summary, while Google Trends analysis showed that schools may play a role in increasing interest and awareness online, quality of information and readability analysis displayed that the information and its accessibility are far too variable to be reliable.

Background: Children with disabilities are twice as likely to have overweight/obesity than their typically developing peers. Higher weights in these individuals may compound challenges already experienced with their disability, including mobility and activities of daily living. However, children with disabilities often find it challenging accessing weight management care. It is therefore important to understand the experiences and needs of the health care professionals (HCPs) who work in specialized pediatric weight management clinics about providing weight-related care to children with disabilities. Methods: Employing an interpretive description approach, purposeful sampling was used to recruit 17 HCP participants working in pediatric weight management settings in Canada. Qualitative semistructured interviews were conducted online or via telephone. All interview recordings were transcribed and a reflexive thematic analysis approach was used to develop themes from the data. Results: Four themes were developed: (1) infrequent referrals leads to a lack of experience with children with disabilities; (2) adapting group-based clinics can be challenging; (3) perceived lack of disability-specific knowledge causes moral distress; and (4) disability-specific training and greater interdisciplinary collaboration are desired. Conclusions: This work identifies the urgent need for more evidence-based, specialized, weight-related treatment options for children with disabilities, as well as more support for HCPs working in existing programs.

Background: Transgender/gender diverse (TGD) youth are at risk for weight-related problems. We describe factors associated with their body mass index (BMI) category. Methods: Chart review of 228 TGD patients, 12-20 years (u = 15.7, standard deviation 1.3), 72% female assigned at birth. BMI percentile was calculated using CDC growth charts. We examined bivariate relationships of 18 clinically derived factors, utilizing analysis of variance (ANOVA) for continuous variables and chi-squared/Fisher's exact test for categorical variables. Nonparametric Classification and Regression Tree (CART) analyses were used to predict BMI category. Results: Almost half (49.6%) of TGD youth presenting for their initial visit for pediatric gender-affirming care fell in the healthy weight range, 4.4% in the underweight range, 16.7% in the overweight range, and 29.4% in the obese range. Self-described weight, weight management intentions, unhealthy weight management, prescription of psychiatric medications, and medications associated with weight gain were associated with BMI category. Use of psychiatric medications (54.8%) and medications associated with weight gain (39.5%) was associated with BMI in the overweight/obese categories. Youth with obesity most often reported unhealthy weight management. In CART models, self-described weight was the strongest predictor of BMI category. Conclusion: TGD youth have high rates of underweight and overweight/obesity. Unhealthy BMI should be treated as part of gender-affirming care. Self-described body weight is associated with weight category. More than half of TGD youth were prescribed psychiatric medications; those with overweight and obesity were more likely prescribed psychiatric and medications with associated weight gain. Youth with obesity were most likely to use unhealthy weight management.

Background: Childhood obesity can be addressed through family-based pediatric weight management; however, treatment enrollment in the United States is low. This study aimed to identify parental factors associated with intentions to initiate a family-based pediatric weight management program. Methods: Cross-sectional survey data were collected from an online panel of US parents with at least one 5- to 11-year-old child identified as likely to have overweight or obesity. Participants viewed a video about a hypothetical family-based pediatric weight management program, rated their 30-day initiation intentions for that program, and answered additional related questionnaires. Results: Participants (n = 158) identified as White/Caucasian (53%) or Black/African American (47%), were primarily female (61.4%) and married/cohabitating (81.6%) with children who were predominantly girls (53.2%) and, on average, 9-year-olds. Higher parents' perception of program effectiveness predicted initiation intentions (p < 0.001), while concern for their child's weight and parent depression and anxiety levels did not. Higher initiation intentions and perceived program effectiveness were reported by Black/African American participants (p < 0.01) and those with at least a bachelor's degree (p < 0.01) compared to White/Caucasian participants and those without a bachelor's degree, respectively. Initiation intentions were higher for those with greater financial security (p = 0.020) and fewer than three children in the home (p = 0.026). Participants endorsed initiation barriers of time constraints (25%), possible lack of enjoyment for the child (16.9%), and lack of family support (15%). Conclusions: Future program enrollment efforts may need to focus on strategies to increase perceived program effectiveness, although further research is needed that measures actual enrollment in real-world contexts.

Background: There is a range of responses among individuals seen for medical management of their obesity. This retrospective analysis of longitudinal data considers the relationship between identified prediabetes and subsequent weight change among children (8-17 years) in a weight management clinic. Methods: Analysis included 733 patients (2687 visits in 2008-2016) with overweight and obesity (but not diabetes) whose referral laboratories included a hemoglobin A1c (HbA1c) within 90 days. Mixed-effects modeling examined the association between baseline prediabetes (serum HbA1c 5.7%-6.4%) and growth curve of percentage of the 95th percentile for BMI (%BMIp95). Random effects (individual growth curves) and fixed effects (prediabetes status, starting age and %BMIp95, sex, race/ethnicity, and linear slope and quadratic term of months since the initial visit) were modeled. Interactions between prediabetes and elapsed time estimated the influence of a recent prediabetic-range HbA1c on weight during the subsequent 12 months. Results: Mean %BMIp95 was 125.5% (SD 22.5), corresponding to severe obesity, and 35% had prediabetes. Adjusted monthly decrease in %BMIp95 was stronger for children with prediabetes compared with the peers in this clinic (slope: -0.62, standard error 0.10, p < 0.001). Conclusion: There was greater weight improvement among children with prediabetes compared with their peers with normal HbA1c.

Rates of class III, or greater, obesity have risen among adolescents in the United States. Metabolic and bariatric surgery (MBS) is a safe and effective treatment option for severe obesity among teenagers that results in improvements in cardiometabolic and psychosocial health. Despite its effectiveness, MBS remains largely underutilized and misconceptions exist among providers, parents/guardians, and adolescents. In addition, adolescents who have undergone MBS procedures report there are some topics they wish they had known more about before surgery and express concern that their unique needs are not understood. One potential solution to address these concerns includes preoperative educational materials tailored for adolescents. Currently, there are no standardized recommendations for preoperative educational materials. This editorial suggests the use of community-engaged research, and qualitative methodology, to consult with the primary stakeholder groups of preoperative adolescents, postoperative adolescents, parents/guardians, and clinicians to develop tailored materials that address the unique needs of adolescents undergoing surgical treatment for obesity.
