Pediatric Obesity

OBJECTIVES: This scoping review informs a health economics perspective on the treatment of paediatric obesity. The results detail recently published research findings on the cost-effectiveness of paediatric obesity treatments and identify key characteristics of cost-effective interventions. METHODS: A structured search was applied to six databases with no data restriction through March 2023: Medline, Embase, Cochrane CENTRAL, CINAHL, and PsycINFO. Studies that included a cost analysis of an individual level, weight management intervention (behavioural, pharmacotherapy, and surgical) in youth, with obesity, ages 2 to 21 years were eligible for inclusion...

BACKGROUND: Evidence from Latin America suggests that children embedded in South-to-North migrant networks (i.e. relatives who live abroad, typically in the United States) are at increased risk of excess weight. It is unclear if the same findings apply to children embedded in Latin American intraregional migration or South-to-South migration networks. OBJECTIVE: To compare excess weight among Colombian children embedded in South-to-South migration networks (n = 334) to children with non-migrant parents (n = 4272) using Colombia's 2015 National Survey of the Nutritional Situation...

BACKGROUND: Paediatric obesity disproportionately impacts individuals from minoritized racial and ethnic backgrounds. Recent guidelines support use of anti-obesity pharmacotherapy for adolescents with obesity, but the potential impact on disparities in obesity prevalence has not been evaluated. OBJECTIVES: To model changes in obesity prevalence with increasing utilization of anti-obesity pharmacotherapy among adolescents. METHODS: Data representative of American adolescents ages 12-17 years were obtained from the National Health and Nutrition Examination Survey, cycles 2011 through pre-pandemic 2020...

BACKGROUND: Obesity is a heterogeneous disease with variable treatment response. Identification of the unique constellation of contributors to obesity may allow for targeted interventions and improved outcomes. OBJECTIVE: Identify empirically derived phenotypes of pediatric patients with obesity based on appetitive and psychological correlates of obesity. METHODS: This cross-sectional study included patients aged 5-12 years who were treated in a weight management clinic and completed standard intake questionnaires including Child Eating Behavior Questionnaire (CEBQ), Vanderbilt ADHD Scale and Pediatric Symptom Checklist...

BACKGROUND: The relationship between sugar-free beverage (SFB) intake and childhood obesity among Chinese children is unknown. OBJECTIVES: To describe the status of SFB consumption among children and adolescents in China and assess the association between SFB intake and different types of obesity. METHODS: The study was based on the baseline data of an ongoing cohort project named Evaluation and Monitoring on School-based Nutrition and Growth in Shenzhen (EMSNGS)...

AIMS: This research explores the relationships between food addiction (FA), eating behaviours, and weight status in school-aged children and adolescents, aiming to understand how FA influences weight. METHODS: By using a cross-sectional design, 426 healthy children and their parents were enroled in Eastern China. FA was assessed using the Chinese version of the Dimensional Yale Food Addiction Scale for Children 2.0 (dYFAS-C 2.0), while eating patterns were identified using latent profile analysis (LPA) derived from the Children's Eating Behaviour Questionnaire (CEBQ)...

BACKGROUND: The metabolic load-capacity index (LCI), which represents the ratio of adipose to skeletal muscle tissue-containing compartments, is potentially associated with cardiometabolic diseases. OBJECTIVES: To examine the associations between the LCI and cardiometabolic risk factors in children and youth with obesity. METHODS: This is a cross-sectional study including 10-18 years-old participants with a BMI of ≥95th ...

BACKGROUND: Youth in rural areas are disproportionally affected by obesity. Given the unique barriers rural populations face, tailoring and increasing access to obesity interventions is necessary. OBJECTIVE: This paper evaluates the effectiveness of iAmHealthy, a family-based paediatric obesity intervention delivered to rural children, compared to a Newsletter Control. METHODS: Participating schools (n = 18) were randomly assigned to iAmHealthy or Newsletter Control...

OBJECTIVE: To estimate national and provincial prevalence of obesity and excess weight in the child and adolescent population in Spain by sex and sociodemographic characteristics, and to explore sources of inequalities in their distribution, and their geographical patterns. METHODS: ENE-COVID is a nationwide representative seroepidemiological survey (68 287 participants) stratified by province and municipality size (April-June 2020). Participants answered a questionnaire which collected self-reported weight and height, that allowed estimating crude and model-based standardized prevalences of obesity and excess weight in the 10 543 child and adolescent participants aged 2-17 years...

OBJECTIVE: To investigate population trajectories of behavioural risk factors of obesity from childhood to adolescence and their associations with body mass index (BMI) in children across European regions. METHODS: Data were harmonised between the European multi-centre IDEFICS/I.Family and the Amsterdam Born Children and their Development Cohort. Participants were aged 2.0-9.9 and 5.0-7.5 years at baseline, respectively, and were followed until age 18 years...

BACKGROUND: Cord blood (CB) leptin is positively associated with adiposity at birth, but the association with child adiposity is unclear. OBJECTIVES: We hypothesized that CB leptin is positively associated with adiposity in peripubertal children and with childhood leptin. METHODS: Leptin was measured in 986 CB and 931 childhood stored samples from a prospective birth cohort. Adiposity measures were collected at birth and mean age 11.5 years...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is on the rise among youth. Identifying biomarkers of NAFLD progression/risk can aid in prevention efforts. AIMS: This pilot study investigated associations of two endotoxin biomarkers-lipopolysaccharide-binding protein (LBP) and anti-endotoxin core immunoglobulin G (EndoCab)-with markers of NAFLD among 99 Latino/Latina adolescents (11-19 years) with obesity. MATERIALS & METHODS: We used linear regression to examine associations of each endotoxin biomarker (per 1-SD) with hepatic fat fraction (HFF), liver volume, and liver stiffness...

BACKGROUND AND OBJECTIVES: Breastfeeding during infancy is associated with healthier beverage consumption later in childhood, but little is known about this relation during infancy. This was a longitudinal study of breastfeeding and less healthy beverage consumption during the first year of life, in a birth cohort study conducted 2013-2018 in the Southeastern United States (n = 666). METHODS: We estimated monthly rates of 100% juice and sugar-sweetened beverage (SSB) consumption comparing infants who were exclusively or partially breastfed, versus those who were not, in multivariable adjusted models...

BACKGROUND: Previous research on the association between body mass index (BMI) and visual impairment (VI) in youth has reported inconsistent findings. We aimed to investigate this association in a national cohort of Israeli adolescents. METHODS: This retrospective, population-based, cross-sectional study included 1 697 060 adolescents (56.4% men; mean age 17 years) who underwent mandatory pre-military service assessments from 1993 to 2017. BMI was classified based on the US age- and sex-matched percentiles...

BACKGROUND: There is evidence for a link between hyperactivity and obesity, especially among older children. Both conditions seem to be multifactorial in origin and hypotheses of common underlying issues, such as emotional dysregulation, have been suggested. However, studies of the co-occurrence of the two conditions in younger age groups have been inconclusive. OBJECTIVES: We aimed to study the longitudinal associations of psychological strengths and difficulties at 4 years of age with health behaviours, body composition, physical fitness, and cardiovascular disease (CVD) risk factors 5 years later...

BACKGROUND: Body composition between prepubertal children and adolescents varies, and it is unclear how physical activity and sedentary behaviour affect adolescent body composition. OBJECTIVES: This study aimed to examine the associations of physical activity and screen time with overall and specific fat depots in the general adolescent population. METHODS: In a population-based prospective cohort study, among 3258 adolescents aged 13 years, physical activity and screen time were assessed via self-report questionnaires...

BACKGROUND: Neighbourhood factors are associated with cardiovascular health in adults, but these relationships are under-explored in youth. OBJECTIVES: To characterize the associations between neighbourhood factors and child and adolescent health among youth with obesity. METHODS: Data were drawn from patient health records at a pediatric weight management clinic (n = 2838) and the Child Opportunity Index (COI). Exposures were area-level neighbourhood factors (commute duration, walkability, greenspace and industrial pollutants)...

OBJECTIVE: To examine changes in leukocyte telomere length (LTL) during and after a behavioural weight control program for children with obesity. METHODS: We measured LTL among a cohort of 158 children 8-12 years of age with a body mass index greater than or equal to the 95th percentile for age and sex. Children were 55% female, 29% white, 52% Latinx, 8% Asian and 11% Pacific Islander, other or multiethnic. All children participated in a 6-month, family-based, group behavioural weight control program and were assessed before treatment, after treatment and 1 year after the end of treatment...
