Abstract
Zusammenfassung
Hintergrund Mehr als 340 Millionen Kinder gelten weltweit als übergewichtig oder adipös, ihre Anzahl nahm in den letzten Jahren – auch durch die Coronapandemie – erheblich zu. Eine alternative Behandlung zur Reduzierung des Übergewichts, die in den Empfehlungen bisher keine große Beachtung findet, stellt das sogenannte hochintensive Intervalltraining (HIIT) dar.
Ziel Darstellung der Wirksamkeit von hochintensivem Intervalltraining auf den BMI und Körperfettanteil übergewichtiger und adipöser Kinder im Alter von 6–13 Jahren.
Methode Die Erstellung der systematischen Übersichtsarbeit orientierte sich an den PRISMA-Guidelines. Für die Literaturrecherche wurden die Datenbanken MEDLINE, Cochrane Library, CINAHL, Embase, Sports Medicine & Education Index und Web of Science nach Studien mit hochintensivem Intervalltraining für übergewichtige und adipöse Kinder durchsucht. Die Bewertung der methodischen Studienqualität erfolgte mittels PEDro-Skala, MINORS und Risk of Bias. Die Berichtsqualität wurde anhand von CONSORT und TREND bewertet.
Ergebnisse Es wurden 6 randomisierte kontrollierte Studien und 2 kontrollierte klinische Studien mit 479 HIIT-Teilnehmenden betrachtet. Diese zeigten, dass hochintensives Intervalltraining positive Auswirkungen auf den BMI und Körperfettanteil übergewichtiger und adipöser Kinder hat.
Schlussfolgerung Hochintensives Intervalltraining ist eine kinderfreundliche und zugleich effektive Alternative zur Behandlung von übergewichtigen und adipösen Kindern. Weitere klinische Studien sind erforderlich, um die Ergebnisse zu bekräftigen.

Abstract
Gender-specific differences in the prevalence, incidence, comorbidities, prognosis, severity, risk factors, drug-related aspects and outcomes of various medical conditions are well documented. We present a literature review on the extent to which research in this field has developed over the years, and reveal gaps in gender-sensitive awareness between the clinical portrayal and the translation into gender-specific treatment regimens, guidelines and into gender-oriented preventive strategies and health policies. Subsequently, through the lens of gender, we describe these domains in detail for four selected medical conditions: Asthma, obesity and overweight, chronic kidney disease and coronavirus disease 2019. As some of the key gender differences become more apparent during adolescence, we focus on this developmental stage. Finally, we propose a model which is based on three influential issues: (1) Investigating gender-specific medical profiles of related health conditions, rather than a single disease; (2) The dynamics of gender disparities across developmental stages; and (3) An integrative approach which takes into account additional risk factors (ethnicity, socio-demographic variables, minorities, lifestyle habits etc.). Increasing the awareness of gender-specific medicine in daily practice and in tailored guidelines, already among adolescents, may reduce inequities, facilitate the prediction of future trends and properly address the characteristics and needs of certain subpopulations within each gender.

Abstract
OBJECTIVE The objective of this study was to examine the prevalence and characteristics of comorbidities in obese and morbidly obese children with a comparison between the 2 sets of children. METHODS This was a retrospective electronic chart review of obese and morbidly obese children and adolescents as defined by body mass index. We evaluated medical history of comorbid conditions, medication use, and cardiovascular risk markers, including blood pressure, lipid profile, and glycosylated hemoglobin. RESULTS There were 1,111 subjects (African American = 635; non-Hispanic white = 364; Hispanic = 36; others = 86), of which 274 were obese and 837 were morbidly obese children with a mean age of 12.7 ± 3.37 years. Morbidly obese children had a higher prevalence of prediabetes (19.5% of obese versus 27.3% of morbidly obese; P<.0001) and type 2 diabetes (39.8% of obese versus 52.4% of morbidly obese; P<.0001). Use of medications for treatment of asthma was significantly higher in the morbidly obese group compared with the obese group (21% versus 14%; P = .01). CONCLUSION Morbidly obese children have a higher prevalence of diabetes, prediabetes, and use of asthma medications compared with obese children.

The association between physical activity and healthcare costs in children--results from the GINIplus and LISAplus cohort studies. BMC Public Health 2015; 15:437. [PMID: 25925399 PMCID: PMC4423115 DOI: 10.1186/s12889-015-1721-6] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2014] [Accepted: 03/30/2015] [Indexed: 12/20/2022] Open
Abstract
Background Physical inactivity in children is an important risk factor for the development of various morbidities and mortality in adulthood, physical activity already has preventive effects during childhood. The objective of this study is to estimate the association between physical activity, healthcare utilization and costs in children. Methods Cross-sectional data of 3356 children aged 9 to 12 years were taken from the 10-year follow-up of the birth cohort studies GINIplus and LISAplus, including information on healthcare utilization and physical activity given by parents via self-administered questionnaires. Using a bottom-up approach, direct costs due to healthcare utilization and indirect costs resulting from parental work absence were estimated for the base year 2007. A two-step regression model compared effects on healthcare utilization and costs for a higher (≥7 h/week) versus a lower (<7 h/week) level of moderate-to-vigorous physical activity (MVPA) adjusted for age, gender, BMI, education and income of parents, single parenthood and study region. Recycled predictions estimated adjusted mean costs per child and activity group. Results The analyses for the association between physical activity, healthcare utilization and costs showed no statistically significant results. Different directions of estimates were noticeable throughout cost components in the first step as well as the second step of the regression model. For higher MVPA (≥7 h/week) compared with lower MVPA (<7 h/week) total direct costs accounted for 392 EUR (95% CI: 342–449 EUR) versus 398 EUR (95% CI: 309–480 EUR) and indirect costs accounted for 138 EUR (95% CI: 124–153 EUR) versus 127 EUR (95% CI: 111–146 EUR). Conclusions The results indicate that childhood might be too early in life, to detect significant preventive effects of physical activity on healthcare utilization and costs, as diseases attributable to lacking physical activity might first occur later in life. This underpins the importance of clarifying the long-term effects of physical activity as it may strengthen the promotion of physical activity in children from a health economic perspective.

Korber K. Potential transferability of economic evaluations of programs encouraging physical activity in children and adolescents across different countries--a systematic review of the literature. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2014; 11:10606-21.

Abstract
Physical inactivity is an increasing problem. Owing to limited financial resources, one method of getting information on the cost-effectiveness of different types of prevention programs is to examine existing programs and their results. The aim of this paper is to give an overview of the transferability of cost-effectiveness results of physical activity programs for children and adolescents to other contexts. Based on a systematic review of the literature, the transferability of the studies found was assessed using a sub-checklist of the European Network of Health Economic Evaluation Databases (EURONHEED). Thirteen studies of different physical activity interventions were found and analyzed. The results for transferability ranged from “low” to “very high”. A number of different factors influence a program’s cost-effectiveness (i.e., discount rate, time horizon, etc.). Therefore, transparency with regard to these factors is one fundamental element in the transferability of the results. A major point of criticism is that transferability is often limited because of lack of transparency. This paper is the first to provide both an overview and an assessment of transferability of economic evaluations of existing programs encouraging physical activity in children and adolescents. This allows decision makers to gain an impression on whether the findings are transferable to their decision contexts, which may lead to time and cost savings.

Abstract
The aim of this study is to assess the association between different patterns of Body Mass Index (BMI) development from birth on and later healthcare utilisation and costs in children aged about 10 years based on two birth cohort studies: the GINIplus study (3287 respondents) and the LISAplus study (1762 respondents). Direct costs were estimated using information on healthcare utilisation given by parents in the 10-year follow-up. To meet this aim, we (i) estimate BMI-standard deviation score (BMIZ) trajectories using latent growth mixture models and (ii) examine the correlation between these trajectories and utilisation of healthcare services and resulting costs at the 10-year follow-up. We identified three BMI-trajectories: a normative BMIZ growth class (BMI development almost as in the WHO growth standards), a rapid BMIZ growth up to age 2 years class (with a higher BMI in the first two years of life as proposed by the WHO growth standards) and a persistent rapid BMIZ growth up to age 5 years class (with a higher BMI in the first five years of life as proposed by the WHO growth standards). Annual total direct medical costs of healthcare use are estimated to be on average €368 per child. These costs are doubled, i.e. on average €722 per child, in the group with the most pronounced growth (persistent rapid BMIZ growth up to age 5 years class).

Abstract
As in most countries, overweight and obesity among children and adolescents have dramatically increased in Germany over the last two decades. This serious public-health challenge has stimulated many efforts to curb the pediatric obesity epidemic. In this article, the authors briefly describe these efforts and examine the role of health economics in informing German health policies and evaluating the outcomes of interventions aimed at reducing pediatric obesity. The findings indicate that the tools of health-economic analysis have rarely been used to guide the development of strategies to prevent pediatric obesity and to support decision-making on the use of the scarce resources available for preventive actions. The authors give some reasons why health economics has not been an important policy tool so far and make some recommendations for how this could be changed. Reasons impeding health economics playing a more important role in this area are the existence of many unsolved issues in the methods of health economic evaluation and large gaps in the knowledge base on the effectiveness of interventions. Nevertheless, these methods should be considered to be indispensible tools of health policy development. However, taking into account the broad range of political and societal concerns related to pediatric obesity, decision-making in this area will ultimately rest on a process of deliberate thinking integrating different perspectives among, which health economics will be one.

Abstract
Objectives: To test the effects of body weight maintenance, gain, and loss on health care utilisation in terms of outpatient visits to different kinds of physicians in the general adult population. Methods: Self-reported utilisation data were collected within two population-based cohorts (baseline surveys: MONICA-S3 1994/95 and KORA-S4 1999/2001; follow-ups: KORA-F3 2004/05 and KORA-F4 2006/08) in the region of Augsburg, Germany, and were pooled for present purposes. N=5,147 adults (complete cases) aged 25 to 64 years at baseline participated. Number of visits to general practitioners (GPs), internists, and other specialists as well as the total number of physician visits at follow-up were compared across 10 groups defined by body mass index (BMI) category maintenance or change. Body weight and height were measured anthropometrically. Hierarchical generalized linear regression analyses with negative binomial distribution adjusted for sex, age, socioeconomic status (SES), survey, and the need factors incident diabetes and first cancer between baseline and follow-up were conducted. Results: In fully adjusted models, compared to the group of participants that maintained normal weight from baseline to follow-up, the following groups had significantly higher GP utilisation rates: weight gain from normal weight (+36%), weight loss from preobesity (+39%), maintained preobesity (+34%), weight gain after preobesity (+43%), maintained moderate obesity (+48%), weight gain from moderate obesity (+107%), weight loss from severe obesity (+114%), and maintained severe obesity (+83%). Regarding internists, those maintaining moderate obesity reported +107% more visits; those with weight gain from moderate obesity reported +91%. The latter group also had +41% more consultations with other physicians. Across all physicians, mean number of visits were estimated at 7.8 per year for maintained normal weight, 9 for maintained preobesity, 11 for maintained moderate obesity, and 12 for maintained severe obesity. Among those with weight loss, the mean number of visits were 8.7, 10.6 and 10.8 for baseline preobesity, moderate obesity, and severe obesity, respectively. Finally, those with weight gain from normal weight and preobesity reported 9.4 and 9.3 visits, respectively, and those with baseline moderate and follow-up severe obesity reported 13.1 visits (the most overall). Women reported higher GP and other physician utilisation. While all utilisation rates increased with age, GP utilisation was lower in middle to high SES groups. Conclusion: Compared to maintained normal weight over a 7- to 10-year period, maintained overweight, weight gain and weight loss are associated with higher outpatient physician utilisation in adults, especially after baseline obesity. These effects only partly became insignificant after inclusion of incident diabetes or first cancer into the model. Future research should further elucidate the associations between weight development and health care utilisation by BMI status and the mechanisms underlying these associations.

Abstract
The obesity epidemic has transformed children's healthcare, such that diabetes, hypertension and the metabolic syndrome are phrases more commonly used by child health providers than ever before. This article reviews the economic consequences of this epidemic for healthcare delivery systems, both in the short term when obesity has been associated with increased utilization, and in the long term where increased likelihood of adult obesity and cardiovascular disease is well documented. Large investments through research and prevention are needed and are likely to provide strong returns in cost savings, and would optimally emerge through a cooperative effort between private and government payers alike.

Abstract
OBJECTIVE This review aims to put an economic perspective on childhood and adolescent obesity by providing an overview on the latest literature on obesity-related costs and the cost effectiveness of interventions to prevent or manage the problem. METHODS The review is based on a comprehensive PubMed/Medline search performed in October 2011. RESULTS Findings on the economic burden of childhood obesity are inconclusive. Considering the different cost components and age groups, most but not all studies found excess health care costs for obese compared with normal-weight peers. The main limitations relate to short study periods and the strong focus on health care costs, neglecting other components of the economic burden of childhood obesity. The results of the economic evaluations of childhood and adolescent obesity programs support the expectation that preventive and management interventions with acceptable cost effectiveness do exist. Some interventions may even be cost saving. However, owing to the differences in various methodologic aspects, it is difficult to compare preventive and treatment approaches in their cost effectiveness or to determine the most cost-effective timing of preventive interventions during infancy and adolescence. CONCLUSION To design effective public policies against the obesity epidemic, a better understanding and a more precise assessment of the health care costs and the broader economic burden are necessary but, critically, depend on the collection of additional longitudinal data. The economic evaluation of childhood obesity interventions poses various methodologic challenges, which should be addressed in future research to fully use the potential of economic evaluation as an aid to decision making.

Abstract
Over the last two decades, the prevalence of obesity has risen worldwide. As obesity is a confirmed risk factor for a number of diseases, its increasing prevalence nurtures the supposition that obesity may present a growing and significant economic burden to society. The objective of this study is to analyse the correlation between body mass index (BMI) and future direct and indirect costs, as well as the correlation between changing BMI and future in(direct) costs. Health care utilisation and productivity losses were based on data from 2581 participants aged 25-65 years (1994/95) from two cross-sectional, population-representative health surveys (MONICA/KORA-survey-S3 1994/95 and follow-up KORA-survey-F3 2004/05) in Augsburg, Germany. The predicted average adjusted total direct costs per year and per user were estimated to be €1029-(healthy weight), €1093-(overweight) and €1040-(obesity). There are significantly greater future costs in the utilisation of general practitioners per user and per year at higher obesity levels (€72; €75; €96). The average total direct costs per person for those who stay in the same BMI class are €982, €1000 and €973. An overweight participant who becomes obese incurs significant costs of internists of €160 compared with those who remain overweight (€124). An overweight user incurs indirect costs of €2474, compared with €2136 for those who remain a healthy weight. There is a trend for higher predicted (in)direct costs when people are overweight or obese compared with healthy weight persons 10 years earlier. Potential cost savings could be attained if preventive programs effectively targeted these individuals.

Abstract
BACKGROUND Childhood obesity is a growing public health burden. Among German children and adolescents, 15% are overweight (including obese) and 6.3% are obese according to a national reference. This is the first German study to assess aspects of the economic burden associated with overweight and obesity in children and adolescents based on a representative cross-sectional survey. METHODS Based on the German Interview and Examination Survey for Children and Adolescents (KiGGS), direct costs induced by utilisation of healthcare services (physician and therapist visits, hospital stays) were assessed using a bottom-up approach. To investigate the impact of body mass index (BMI) on costs, univariate analyses were performed and multivariate generalised mixed models were estimated. RESULTS Average annual total costs were estimated to be €442 (95% CI [402-486]). Bivariate analysis showed considerable differences between BMI groups in physician costs, but not for hospital or therapist costs. High socioeconomic status, residence in west Germany and underweight had a significant negative impact on total costs in multivariate analysis. The effect of overweight on total costs is positive but not significant; neither is the effect of obesity. However, overweight and obese children exhibit significantly higher physician costs and a higher probability of being high utilisers of healthcare services. DISCUSSION The economic implications of overweight and obesity are, to some extent, already visible in childhood. The results suggest that obese children should be classified as priority group for prevention. Despite limitations, this study provides important information concerning the relevance of childhood obesity as a health problem.

Abstract
Obesity among children and adolescents is a growing public health burden. According to a national reference among German children and adolescents aged 3-17 years, 15% are overweight (including obese) and 6.3% are obese. This study aims to assess the economic burden associated with overweight and obesity in children based on a cross-sectional survey from two birth cohort studies: the GINI-plus - German Infant Nutritional Intervention plus Non-Intervention study (3287 respondents aged 9 to <12 years) and the LISA-plus study - Influence of life-style factors on the development of the immune system and allergies in East and West Germany (1762 respondents aged 9 to <12 years). Using a bottom-up approach, we analyse direct costs induced by the utilisation of healthcare services and indirect costs emerging from parents' productivity losses. To investigate the impact of Body Mass Index (BMI) on costs, we perform various descriptive analyses and estimate a two-part regression model. Average annual total direct medical costs of healthcare use are estimated to be €418 (95% CI [346-511]) per child, split between physician (22%), therapist (29%), hospital (41%) and inpatient rehabilitation costs (8%). Bivariate analysis shows considerable differences between BMI groups: €469 (severely underweight), €468 (underweight), €402 (normal weight), €468 (overweight) and €680 (obese). Indirect costs make up €101 per year on average and tend to be higher for obese children, although this was not statistically significant. Drawing on these results, differences in healthcare costs between BMI groups are already apparent in children.

Abstract
PURPOSE OF REVIEW The rising prevalence of obesity amongst children and adolescents is a growing public health burden. This study reviews recent studies, first, examining the economic consequences of childhood obesity, and, second, evaluating the cost-effectiveness of programs to prevent and to manage childhood obesity. RECENT FINDINGS Evidence of the impact of childhood obesity on healthcare costs for children is ambiguous. Although one study did not find increasing costs with increasing body mass index (BMI), in some other studies this effect was visible--partly only in subgroups. The evaluation studies show that in order to reach acceptable cost-effectiveness values, interventions cannot focus solely on physical activity, but must include nutrition as an intervention target. Moreover, there is some evidence supporting the expectation that childhood obesity prevention may be successful in combining health gains with net cost savings. SUMMARY There is a need to estimate the costs of childhood obesity as an essential part of identifying cost-effective treatment and prevention measures. Given the diversity and shortcomings of the methodological approaches chosen in the existing evaluation studies, there is an urgent need both for more standardized economic evaluations of those measures and more methodological research.

Abstract
Pediatric obesity is increasing worldwide and disproportionately affects the economically and socially disadvantaged. Obese children are at risk of developing the (dys)metabolic syndrome, insulin resistance, early-onset type 2 diabetes mellitus, polycystic ovarian syndrome, hypertension, hyperlipidemia, and obstructive sleep apnoea. Those with diabetes may have mixed features of type 1 and type 2 diabetes mellitus. Pediatric obesity is the result of persistent adverse changes in food intake, lifestyle, and energy expenditure. It may be because of underlying a genetic syndrome or a conduct disorder. Children living in urban settings often lack safe, affordable, and accessible recreational facilities. Tight educational schedules mean less free time, while computer games and television have become preferred recreational activities. More families are eating out or eating take-out meals and processed foods at home because of pressures of work and time constraints. Consumer advertising targeted at children and the ready availability of vending machines encourage unwise food choices. Some children eat excessively because they are depressed, anxious, sad, or lonely. Often families and obese children are aware of the need for healthy eating and exercise but are unable to translate knowledge into weight loss. Population-based measures such as public education, school meal reforms, child-safe exercise friendly environments, and school-based and community-based exercise programs have been shown to be successful to varying degrees, but there remain individuals who will need special help to overcome obesity. Overeating (e.g. binge eating) may be a manifestation of disordered coping behavior but may also be because of defects in the neural and hormonal control of appetite and satiety. New pharmacological approaches are targeting these areas. We need a coordinated approach involving government, communities, and healthcare providers to provide a continuum of population-based interventions, focused screening, and personalized multidisciplinary interventions for the obese child and family.
