Health related quality of life associated with extreme obesity in adolescents - results from the baseline evaluation of the YES-study.

ABSTRACT: BACKGROUND:Obesity can significantly reduce health-related quality of life (HRQoL) and may lead to numerous health problems even in youths. This study aimed to investigate whether HRQoL varies among youths with obesity depending on grade of obesity and other factors. METHODS:For the Youths with Extreme obesity Study (YES) (2012-2014), a prospective multicenter cohort study, a baseline sample of 431 obese and extremely obese adolescents and young adults (age 14 to 24?years, BMI ?30?kg/m2) was recruited at four German university medical centers and one job center. Obesity grade groups (OGG) were defined according to BMI (OGG I: 30-34.9?kg/m2, OGG II: 35-39.9?kg/m2, OGG III (extreme obesity): ?40?kg/m2). HRQoL was measured with the Euroqol-5D-3?L (EQ-5D-3?L), DISABKIDS chronic generic (DCGM-31) and the KINDLR obesity module. Differences between OGGs were assessed with logistic and linear regression models, adjusting for age, sex, and study center in the base model. In a second regression analysis, we included other characteristics to identify possible determinants of HRQoL. RESULTS:Three hundred fifty-two adolescents (mean age: 16.6 (±2.4), mean BMI: 39.1 (±7.5) kg/ m2) with available HRQoL data were analysed. HRQoL of youths in all OGGs was markedly lower than reference values of non-obese adolescents. Adjusting for age and sex, HRQoL of youths in OGG III significantly impaired compared to OGG I. Youths in OGG III were 2.15 times more likely to report problems with mobility in the EQ-5D-3?L than youths in OGG I. A mean difference of 9.7 and 6.6 points between OGG III and I were found for DCGM-31 and KINDL respectively and 5.1 points between OGG II and I for DCGM-31. Including further variables into the regression models, showed that HRQoL measured by DCGM-31 was significantly different between OGGs. Otherwise, female sex and having more than 4?h of daily screen time were also associated with lower HRQoL measured by DCGM-31 and KINDL. CONCLUSION:HRQoL of adolescents with obesity is reduced, but HRQoL of adolescents with extreme obesity is particularly affected. Larger and longitudinal studies are necessary to understand the relation of extreme obesity and HRQoL, and the impact of other lifestyle or socioeconomic factors.

Project description:BackgroundThe well-being of persons with overweight and obesity, in particular of children and adolescents, may be impaired. The present study investigates the health-related quality of life (HRQoL) of girls and boys with overweight and obesity living in Germany as compared to those of normal-weight, while taking a selection of relevant determinants of HRQoL into account.MethodsThe sample comprises 1771 children and adolescents aged 11 to 17 years that took part in the cross-sectional German Health Interview and Examination Survey for Children and Adolescents (KIGGS Wave 2, 2014-2017). Sex-and age-specific BMI (kg/m2) percentiles were utilized to classify overweight and obesity. HRQoL was measured with the KIDSCREEN-27 questionnaire, which gathers detailed information about the five dimensions physical and psychological well-being, well-being regarding peers (i.e., social acceptance), parents (i.e., autonomy) and within the school environment. Multiple regression analyses were performed with HRQoL dimensions as outcomes to test for differences between children and adolescents with normal-weight vs. those with overweight and vs. those with obesity, separately for girls and boys. In a next step, age, physical activity, media consumption, social support and self-efficacy were considered as potential confounders in the analyses.Results18.7% of the children and adolescents under study were affected by overweight and among them 8.0% by obesity. After adjusting for potential confounders, overweight and obesity were associated with lower physical well-being as compared to normal weight in both sexes (boys with overweight: standardized beta [β] = -.14, standard error [SE] = .03, p < .001, and obesity: β = -.16, SE = .03, p < .001; girls with overweight: β = -.09, SE = .04, p = .011, and obesity: β = -.11, SE = .03, p = .003). Results moreover suggest lower levels of psychological (β = -.10, SE = .04, p = .002) and parent-related well-being (β = -.08, SE = .04, p = .036) of boys with obesity as compared to normal-weight peers.ConclusionHRQoL of German children and adolescents with overweight and obesity is impaired according to physical well-being in general, while psychological and parent-related well-being is particularly affected in boys. Public health approaches should therefore promote children and adolescents with overweight and obesity by improving diverse facets of HRQoL as well as relevant associated factors (i.e., media consumption, self-efficacy) in general and in boys in particular.

Project description:IntroductionChildren and adolescents with overweight and obesity have an impaired health-related quality of life (HRQoL). However, it is unclear which of these children are most affected in their physical, psychological, and social functioning. Therefore, this study aimed to evaluate HRQoL in treatment-seeking children and adolescents with overweight, obesity, and severe obesity.MethodsA cross-sectional study was performed at the Centre for Overweight Adolescent and Children's Healthcare (COACH). Children and adolescents (8-17 years) with overweight, obesity, and severe obesity were included. The primary outcome was the self-reported HRQoL measured with the KIDSCREEN-27.ResultsA total of 419 participants with overweight (N = 121), obesity (N = 182), and severe obesity (N = 116) were included. One-way ANOVA analysis showed that children and adolescents with severe obesity reported significantly lower physical well-being (41.25 ± 13.14) compared to those with overweight (47.91 ± 12.53; p < 0.001) and obesity (46.74 ± 11.93; p < 0.001). Furthermore, impaired psychological well-being was found in the group with severe obesity (45.14 ± 13.27) in comparison to the group with overweight (50.90 ± 9.48; p < 0.001) and obesity (49.71 ± 10.95; p = 0.002). Multivariable linear regression analysis, while correcting for age, sex, cardio metabolic health risk, and ethnicity, revealed similar results. Additionally, children and adolescents with severe obesity scored lower regarding autonomy and parent relation than those with overweight (B = 3.95; p = 0.009). In almost all groups and dimensions of the KIDSCREEN-27, caregivers scored lower compared to the children and adolescents themselves. Furthermore, a low child-caregiver agreement seemed to exist, especially in the children and adolescents with overweight.ConclusionThe HRQoL of treatment-seeking children and adolescents with overweight and obesity was most affected in children and adolescents with the most severe grade of obesity. Following these findings, lifestyle intervention programs targeting childhood obesity should be aware of this even more vulnerable group so that treatments can be tailored according to their needs.

Project description:Prevalence rates of overweight and obesity have increased in German children and adolescents in the last three decades. Adolescents with extreme obesity represent a distinct risk group. On the basis of data obtained by the German Child and Youth Survey (KiGGS) and the German district military offices we estimate that the group of extremely obese adolescents (BMI???35 kg/m2) currently encompasses approximately 200.000 adolescents aged 14 to 21 yrs. Conventional approaches focusing on weight reduction have largely proven futile for them. In addition, only a small percentage of adolescents with extreme obesity seek actively treatment for obesity while contributing disproportionately strong to health care costs. Because of somatic and psychiatric co-morbidities and social problems adolescents with extreme obesity require special attention within the medical care system. We have initiated the project "Medical and psychosocial implications of adolescents with extreme obesity--acceptance and effects of structured care, short: 'Youths with Extreme Obesity Study (YES)'", which aims at improving the medical care and social support structures for youths with extreme obesity in Germany.We focus on identification of these subjects (baseline examination) and their acceptance of diagnostic and subsequent treatment procedures. In a randomized controlled trial (RCT) we will investigate the effectiveness of a low key group intervention not focusing on weight loss but aimed at the provision of obesity related information, alleviation of social isolation, school and vocational integration and improvement of self-esteem in comparison to a control group treated in a conventional way with focus on weight loss. Interested individuals who fulfill current recommended criteria for weight loss surgery will be provided with a structured preparation and follow-up programs. All subjects will be monitored within a long-term observational study to elucidate medical and psychosocial outcomes. Our aim is to evaluate realistic treatment options. Therefore inclusion and exclusion criteria are minimized. We will recruit adolescents (age range 14-21 years) with extreme obesity (BMI???35 kg/m2) (extreme group) within 24 months (120 per centre, 5 centres) as well as obese adolescents being at risk for developing extreme obesity (BMI???30-34.9 kg/m2) (at risk group). Follow-up evalutations will be performed biannually after inclusion for several years depending on additional funding. In sum, we aim at establishing evaluated health care structures for extremely obese adolescents.The results of YES will be of importance for a frequently neglected group of individuals, for whom current medicine has little to offer in terms of structured access to empirically evaluated therapeutic programs. Thus, the results will be both a help for the adolescents within the study and for others in the future given that the trial will lead to a positive finding. Moreover, it will help practitioners and therapists to deal with this neglected group of individuals.Project registration numbers for each subproject: 1.)

Project description:BackgroundAutonomy is recognized as important for individual well-being and constitutes one dimension in the KIDSCREEN-instrument measuring health related quality of life (HRQoL) in children and adolescents. However, the autonomy questions in KIDSCREEN are restricted to opportunities to influence leisure time activities, which is a form of autonomy as volition. Yet, there are other aspects of autonomy that might be related to adolescent's HRQoL. The aims of the present study were first to investigate the psychometric properties of a scale measuring autonomy in adolescence from a control perspective (AAC) including its relation to the autonomy dimension in KIDSCREEN, and second; to investigate AACs ability to predict each of the 10 dimensions constituting KIDSCREEN.MethodsStudents (n = 154) aged 15-16 years who were recruited from schools located in both low (two schools) and high (two schools) socioeconomic status (SES) areas in Sweden participated in a cross-sectional study. The adolescents answered a questionnaire including a new 6-item scale measuring perceived autonomy and HRQoL assessed by the KIDSCREEN-52 instrument. A factor analyses was computed to investigate the relation between the items in the AAC scale and the autonomy items in the KIDSCREEN instrument. Hierarchical regression analyses were computed to investigate if the AAC scale predicted HRQoL in any of the 10 dimensions in KIDSCREEN after controlling for gender, SES and the original autonomy scale included in KIDSCREEN.ResultsThe factor analysis showed that all the items from the autonomy scale loaded in one factor and that all the items from the AAC scale loaded in another dimension. The hierarchical regression models showed that the AAC scale uniquely predicted HRQoL in all dimensions of the KIDSCREEN instrument after controlling for gender, SES and the original autonomy scale included in KIDSCREEN-52. A high level of perceived autonomy was associated with a high level of HRQoL for both scales.ConclusionA new scale for measuring autonomy from a control perspective has been presented and shown to differ from autonomy as volition. Both forms of autonomy are positively related to HRQoL in adolescence 15-16 years old.

Project description:AimsCross-sectional studies demonstrated associations of several sociodemographic and psychosocial factors with generic health-related quality of life (HRQoL) in children and adolescents. However, little is known about factors affecting the change in child and adolescent HRQoL over time. This study investigates potential psychosocial risk and protective factors of child and adolescent HRQoL based on longitudinal data of a German population-based study.MethodsData from the BELLA study gathered at three measurement points (baseline, 1-year and 2-year follow-ups) were investigated in n = 1,554 children and adolescents aged 11 to 17 years at baseline. Self-reported HRQoL was assessed by the KIDSCREEN-10 Index. We examined effects of sociodemographic factors, mental health problems, parental mental health problems, as well as potential personal, familial, and social protective factors on child and adolescent HRQoL at baseline as well as over time using longitudinal growth modeling.ResultsAt baseline, girls reported lower HRQoL than boys, especially in older participants; low socioeconomic status and migration background were both associated with low HRQoL. Mental health problems as well as parental mental health problems were negatively, self-efficacy, family climate, and social support were positively associated with initial HRQoL. Longitudinal analyses revealed less increase of HRQoL in girls than boys, especially in younger participants. Changes in mental health problems were negatively, changes in self-efficacy and social support were positively associated with the change in HRQoL over time. No effects were found for changes in parental mental health problems or in family climate on changes in HRQoL. Moderating effects for self-efficacy, family climate or social support on the relationships between the investigated risk factors and HRQoL were not found.ConclusionThe risk factor mental health problems negatively and the resource factors self-efficacy and social support positively affect the development of HRQoL in young people, and should be considered in prevention programs.
