Obesity in children and adolescents: epidemiology, causes, assessment, and management.

This Review describes current knowledge on the epidemiology and causes of child and adolescent obesity, considerations for assessment, and current management approaches. Before the COVID-19 pandemic, obesity prevalence in children and adolescents had plateaued in many high-income countries despite levels of severe obesity having increased. However, in low-income and middle-income countries, obesity prevalence had risen. During the pandemic, weight gain among children and adolescents has increased in several jurisdictions. Obesity is associated with cardiometabolic and psychosocial comorbidity as well as premature adult mortality. The development and perpetuation of obesity is largely explained by a bio-socioecological framework, whereby biological predisposition, socioeconomic, and environmental factors interact together to promote deposition and proliferation of adipose tissue. First-line treatment approaches include family-based behavioural obesity interventions addressing diet, physical activity, sedentary behaviours, and sleep quality, underpinned by behaviour change strategies. Evidence for intensive dietary approaches, pharmacotherapy, and metabolic and bariatric surgery as supplemental therapies are emerging; however, access to these therapies is scarce in most jurisdictions. Research is still needed to inform the personalisation of treatment approaches of obesity in children and adolescents and their translation to clinical practice.

Is online self-regulatory training effective in weight control? A pilot experiment on adolescence obesity during coronavirus-19 lockdown.

OBJECTIVE: Studies have shown that obesity is associated with decreased executive function. Impaired executive functions lead to poor self-regulation, which in turn may result in persistence of unhealthy behaviors, including eating behaviors, throughout life. Increasing self-regulation in childhood and adolescence has positive effects on creating healthy behaviors such as reducing unnecessary eating and changing unhealthy eating habits. The main purpose of this study is to evaluate an intervention package based on cognitive self-regulation training in changing eating behaviors and reducing obesity in children and adolescents. METHODS: Fifty-six students with obesity aged 12-16 years participated in the study in three groups (cognitive self-regulation training [CSRT], diet, and control). The CSRT group received twenty 30-min online training sessions with a diet over 10 weeks. The diet group received only a diet with no other intervention, and the control group did not receive any intervention. RESULTS: The results of our 2 × 3 repeated-measures ANOVA showed that the CSRT group had a mean BMI decrease of 2.21 (kg/m² ) after ten weeks, and 3.24 (kg/m² ) at the follow-up time. The diet group had a BMI decrease of 0.49 (kg/m² ) at the ten weeks. In addition, the results showed that the CSRT had a significant reduction in eating behaviors such as external eating and emotional eating. However, the other two groups showed no changes in eating behaviors. CONCLUSIONS: Our results show that online cognitive self-regulation training has been effective in weight loss and eating behaviors. This study shows promising evidence for the efficacy of the online CSRT-training as a weight stabilization intervention in children with obesity.

Talking About Childhood Obesity.

While discussing obesity with pediatric patients and their families can be difficult, it is an essential step toward appropriate weight management. There is paucity of data regarding language preferences when discussing obesity in this population. In this pilot qualitative study, we interviewed 8 parents of patients diagnosed with obesity to identify language and communication preferences for discussing their child's weight. Interviews were analyzed for emerging themes. Important trends appeared revealing that parents prefer neutral, medical terms discussed at well-child checks or obesity-specific visits. Providers should frame lifestyle changes as positive for all patients and set achievable goals with the help of visual aids. Our analysis uncovered several important communication strategies that can better equip providers to discuss obesity with their pediatric patients. This research may serve as a foundation for larger studies into the topic.

Randomized controlled trial to test the efficacy of a brief, communication-based, substance use preventive intervention for parents of adolescents: Protocol for the SUPPER Project (Substance Use Prevention Promoted by Eating family meals Regularly).

BACKGROUND: Substance use among adolescents in the U.S. is associated with adverse physical and mental health outcomes in the long-term. Universal youth-focused substance use prevention programs have demonstrated effectiveness but are often not sustainable due to the significant amount of time, effort, and resources required. We describe a trial protocol for a brief, low-participant-burden intervention to improve substance use-specific parent-child communication through the promotion of family meals and increased parental engagement. METHODS: This study is a parallel-group randomized controlled trial designed to assess the efficacy of a 13-week intervention. A total of 500 dyads of parents and their 5th-7th grade children are recruited from across Massachusetts. Dyads are randomized to the intervention or attention-control condition using block urn randomization, based on child grade, gender, and school. Parents/guardians in the substance use preventive intervention arm receive a short handbook, attend two meetings with an interventionist, and receive two SMS messages per week. Parents/guardians in the control arm receive the same dose but with content focused on nutrition, physical activity, and weight stigma. Participant dyads submit videos of family meals, audio recordings of prompted conversations, and quantitative surveys over an 18-month period (baseline, 3, 6, 12, 18 months post-intervention). The primary outcomes measure the quantity and quality of parent-child substance use conversations and proximal child indicators (i.e., substance use attitudes and expectancies, affiliation with substance-using peers, and intentions and willingness to use substances). The secondary outcome is child substance use initiation. DISCUSSION: This is a novel, brief, communication-focused intervention for parents/guardians that was designed to reduce participant burden. The intervention has the potential to improve parent-child engagement and communication and conversations about substance use specifically and decrease child substance use risk factors and substance use initiation. TRIAL REGISTRATION: ClinicalTrials.gov NCT03925220. Registered on 24 April 2019.

Telehealth: A Useful Tool for the Management of Nutrition and Exercise Programs in Pediatric Obesity in the COVID-19 Era.

The COVID-19 pandemic has led to the implementation of policies that mandate various restrictions on daily life, including social distancing, the closure of public services and schools, and movement limitations. Even though these restrictive measures decreased the COVID-19 spread, they may have detrimental effects on various lifestyle components such as physical inactivity, sedentary behavior, and dietary habits, influencing the maintenance of weight and contributing to obesity among children and adolescents. The coexistence of childhood obesity and COVID-19 and changes in the bioecological environment have put children and adolescents at increased risk for developing obesity and exacerbating the severity of this disorder. The use of telehealth technology is a modern approach useful for the delivery of health care services by health care professionals, where distance is a critical factor. Telehealth is effective in promoting increased self-monitoring and behavioral change, and provides the opportunity to perform online nutritional support and exercise training programs to promote a healthy lifestyle and reduce sedentary behaviors in children and adolescents. Telehealth, including tele-exercise and tele-nutrition, has the potential to address many of the key challenges in providing health services, including in patients with obesity during the COVID-19 outbreak. This narrative review aims to describe the role of telehealth as an opportunity in the management of pediatric obesity in the COVID-19 era, and to deliver nutrition and exercise programs for the maintenance of health.

The lockdown effects on a pediatric obese population in the COVID-19 era.

BACKGROUND: The social consequences of COVID-19 pandemic are universally known. In particular, the pediatric population is dealing with a radical lifestyle change. For some risk categories, such as overweight or obese children, the impact of home confinement has been greater than for others. The increased sedentary life, the wrong diet and social distancing have stopped the chance of losing weight. The aims of this study were to analyse the impact of COVID-19 lockdown on the behavior changes in a obese pediatric population and to explore the correlation between the new lifestyle and the level of parental instruction. METHODS: Data show features of 40 obese and overweight pediatric patients of our Clinic in Messina (Italy). We evaluated weight, height, BMI and other biochemical parameters: total cholesterol, HDL, LDL, triglyceride, transaminases, glycemia and insulinemia. After the lockdown, we contacted all patients in order to get some information about diet, physical activity and sedentary lifestyle changes in correlation to the level of their parents' instruction. Additionally, we also evaluated 20 children twice from a clinical and laboratory perspective. RESULTS: The study showed an increase of daily meals during COVID-19 lockdown (3.2 ± 0.4 vs 5 ± 1, P < 0.001). In particular, children whose parents have primary school diploma ate a greater significant number of meals during the lockdown, compared to those who have parents with secondary school diploma (P = 0.0019). In addition, the 95% of patients did low physical activity during the lockdown and the 97.5% spent more time in sedentary activity. Even if BMI's values don't show significant differences, they have increased after the lockdown. We didn't find any correlation between biochemical parameters before and after the lockdown. CONCLUSION: The lockdown has had bad consequences on good style of life's maintenance in overweight and obese children. The absence of a significant correlation between the worsening of biochemical parameters and the lockdown doesn't allow to exclude any long-term consequences. It's safe to assume that, if the hours spent in sedentary activity and the number of meals don't diminish, there will probably repercussion on the biochemical parameters.

COVID-19 related anxiety in children and adolescents with severe obesity: A mixed-methods study.

Recent studies report negative mental health effects of the COVID-19 related lockdown measures in general paediatric cohorts. Since obesity is a risk factor for COVID-19 in adults, children (including adolescents) with obesity might perceive themselves to be vulnerable. Using a combined quantitative and qualitative approach, we explored COVID-19 related anxiety in paediatric patients with severe obesity in the Netherlands using semi-structured telephone interviews and the Paediatric Quality of Life Inventory (PedsQL) questionnaire, which had also been completed by the study population at baseline in the year prior to the COVID-19 outbreak. In total, 75 families participated in the semi-structured telephone interviews during the lockdown, April 2020. Characteristics of included patients were: median age 10.5 years (interquartile range = 7.6-15.2); 52% female; mean BMI standard deviation score 3.8 (SD = 1.0). COVID-19 related anxiety was reported for 24/75 (32%) children. The mean decrease in PedsQL score between baseline visit and COVID-19 outbreak did not differ between children for whom anxiety was reported vs those for whom it was not (mean change -10.3 ± 36.5 vs -3.3 ± 24.4, P = .54). Self-imposed strict quarantine measures were taken by 19/75 (25%) families. During follow-up, several families reported that the previous contact alleviated their anxiety. In conclusion, healthcare professionals should address possible COVID-19 related anxiety in children with severe obesity. Addressing COVID-19 related anxiety could mitigate its potential negative effects.

Parental misperception of their child's weight status and how weight underestimation is associated with childhood obesity.

OBJECTIVES: Obesity is a major public health concern worldwide. This study aims to investigate the accuracy of parental perception of child's weight and related factors as well as how underestimation is associated with the prevalence of childhood obesity. METHODS: Data from 793 parents and respective children (6-10 years) were collected during the spring of 2013 and 2014. Height and weight were measured and used to calculate body mass index and obesity was classified using the International Obesity Task Force. Parents' perception of child's weight and socio-demographic characteristics were accessed by a questionnaire. Statistical tests were used, controlling for biological and social covariates. RESULTS: About 33% of parents misperceived their child's weight, of which 93% underestimated it. Different factors were found associated with greater parental underestimation according to children's weight status (ie, younger age) and sex (ie, higher mother's BMI, lower parental education, and household income for girls; living in an urban place for boys). Underestimation among girls, compared to boys, was more associated with socio-economic features of the family. For both sexes, children with excess weight were more likely to be underestimated by their parents. Parents who underestimated their child's weight were 10 to 20 times more likely to have an obese child. CONCLUSIONS: Findings suggest a social desirability bias in parental reports of child weight status. While some parents recognize their child's weight, others may feel embarrassed to discuss the fact that their child is overweight/obese and may feel reluctant in seeking the advice of a health care professional.

Weighing the Cost of Obesity: One Solution Does Not Fit All For This Complicated Disease.

Obesity causes or contributes to a range of fatal and debilitating health conditions. On top of this, obesity has emerged as one of the largest contributing factors in severe illness and death among those who contract COVID-19, according to several studies.
