Self-rated and parent-rated quality of life (QoL) for community-based obese and overweight children

Somatic complaints as a mediator in the association between body mass index and quality of life in children and adolescents

BACKGROUND

Children and adolescents with overweight are known to have lower Quality of Life (QoL) compared to peers with a normal weight. QoL is a broad concept and is associated with many factors. A better understanding of the factors associated with QoL in children and adolescents and their impact on the association between overweight/obesity and QoL, may help to develop and improve interventions that lead to an improvement in QoL in children/adolescents with a high body mass index (BMI > 25). This study investigated the possible mediating effects of somatic complaints and general practitioner consultations in the association between overweight/obesity and QoL in children and adolescents.

METHODS

For the current study, cross-sectional data were used from a longitudinal study, the DOERAK cohort, collected from general practitioners' medical files and through questionnaires. This cohort included 2-18 year olds with normal weight and overweight. Uni- and multivariate regression analyses were performed to gain more insight into variables associated with QoL. Mediation analyses were performed to investigate the possible mediating effects of somatic complaints and GP consultations in the association between overweight/obesity and QoL in children.

RESULTS

In the total sample of 733 participants aged 2-18 years, participants with normal weight had a significantly higher QoL (83.64, SD10.65) compared to participants with overweight (78.61, SD14.34) and obesity (76.90, SD13.63) at baseline. The multivariate analyses showed that a lower socio-economic status (SES), higher BMIz, and the presence of somatic complaints are associated with a lower QoL. The mediation analysis showed a significant effect of the indirect pathway of BMIz on QoL through somatic complaints (β = - 0.46, 95% CI[- 0.90, - 0.06]).

CONCLUSION

BMIz has a direct impact on QoL in children and adolescents. Somatic complaints seem to mediate the effect of BMIz on QoL.

Poor Health Related Quality of Life and Unhealthy Lifestyle Habits in Weight-Loss Treatment-Seeking Youth

Obesity is associated with unhealthy lifestyle behaviors and poor Health Related Quality of Life (HRQOL). The cumulative effect of lifestyle behaviors on HRQOL has been demonstrated in chronically ill adolescents, but not in adolescents with obesity. The present study aimed to assess the association between HRQOL and adherence to the Mediterranean Diet (MD) and/or low levels of physical activity (PA) in a large sample of outpatient adolescents with overweight or obesity seeking weight loss treatment. Four-hundred-twenty participants were enrolled from 10 Italian outpatient clinics. The demographics and anthropometric features, KIDMED scores, and exercise levels of the participants were collected, together with parental features. The HRQOL was assessed by the Pediatric Quality of Life Inventory (PedsQL™), Adolescents Version 4.0. PedsQL total score and functioning subscales were lower in adolescents who reported one or two unhealthy habits. Compared with the high/intermediate groups, the risk of low HRQOL was twice as high for each unit increase in BMI SDS, while the percentage was reduced by 12.2% for every unit increase in the KIDMED score and by 32.3% for each hour increase of exercise. The clustering of these two unhealthy behaviors conferred a 120% higher risk of low HRQOL. Similarly, adolescents displaying better diet quality and/or a physically more active lifestyle have better physical and psychological functioning. Further studies are needed to disclose whether these characteristics may be predictive of better adherence to weight loss treatment.

Weight Stigma Model on Quality of Life Among Children in Hong Kong: A Cross-Sectional Modeling Study

We proposed a model to examine the relationship among different types of weight-related stigmas and their relationship to quality of life (QoL). We recruited 430 dyads of elementary school children [mean age = 10.07 years; n_boy = 241 (56.0%); n_overweight = 138 (32.1%)] and their parents. Parents completed QoL instruments about their children assessing generic QoL and weight-related QoL. Children completed QoL instruments assessing generic QoL and weight-related QoL and stigma scales assessing experienced weight stigma, weight-related self-stigma, and perceived weight stigma. Experienced weight stigma was significantly associated with perceived weight stigma, and in turn, perceived weight stigma was significantly associated with weight-related self-stigma. However, experienced weight stigma was not directly associated with weight-related self-stigma. In addition, experienced stigma was negatively associated with both child-rated and parent-rated QoL. Perceived weight stigma was associated only with parent-rated weight-related QoL but not child-rated QoL. Self-stigma was associated with child-rated QoL but not parent-rated QoL. Moreover, perceived weight stigma and weight-related self-stigma were significant mediators in the association between body weight and children's QoL; experienced weight stigma was not a significant mediator. The study findings can be used to inform healthcare providers about the relationship among different types of stigmas and their influence on child-rated and parent-rated QoL and help them develop interventions to address the global trend of overweight/obesity in youth and pediatric populations.

Psychological distress and quality of life in Iranian adolescents with overweight/obesity: mediating roles of weight bias internalization and insomnia

PURPOSE

To examine whether weight-related self-stigma (aka weight bias internalization) and insomnia are potential predictors of psychological distress and quality of life (QoL) among Iranian adolescents with overweight (OW)/obesity (OB). To examine whether weight-related self-stigma and insomnia are potential mediators in the relationship between excess weight and health outcomes of distress and QoL.

METHODS

All participants (n = 934; 444 males; mean age = 15.7 ± 1.2 years; zBMI = 2.8 ± 1.0) completed questionnaires on weight-related self-stigma and insomnia at baseline. Six months later, they completed questionnaires on psychological distress and QoL to assess health outcomes. Relationships among variables were tested using mediation analyses with bootstrapping method.

RESULTS

Weight-related self-stigma significantly mediated the effects of zBMI on psychological distress (effect = 0.22; bootstrapping SE = 0.09; 95% CI = 0.08, 0.45), psychosocial QoL (effect = - 0.64; bootstrapping SE = 0.19; 95% CI = - 1.10, - 0.32), and physical QoL (effect = - 1.35; bootstrapping SE = 0.54; 95% CI = - 2.43, - 0.26). Insomnia also significantly mediated the effects of zBMI on psychological distress (effect = 2.18; bootstrapping SE = 0.31; 95% CI = 1.61, 2.81), psychosocial QoL (effect = - 0.89; bootstrapping SE = 0.33; 95% CI = - 1.60, - 0.28), and physical QoL (effect = - 0.83; bootstrapping SE = 0.42; 95% CI = - 1.69, - 0.02). Full mediations were found in psychosocial QoL; partial mediations were found in psychological distress and physical QoL.

CONCLUSIONS

Weight-related self-stigma and insomnia were significant mediators in the effects of excess weight on health outcomes. Therefore, it is important to identify and treat weight-related self-stigma and insomnia for adolescents with OW/OB.

Depression, anxiety, and stress mediate the associations between internet gaming disorder, insomnia, and quality of life during the COVID-19 outbreak

BACKGROUND

For many individuals, the COVID-19 outbreak has increased their psychological distress, changed their behaviors, and impacted their health. With more time spent indoors, many individuals have engaged in increased videogame playing. However, the associations between such behaviors during the COVID-19 outbreak period is unclear.

OBJECTIVE

The present study examined the mediating role of psychological distress (depression, anxiety, and stress) in the association between internet gaming disorder (IGD) and two health outcomes (insomnia quality of life) among adolescents during this COVID-19 pandemic.

METHODS

A cross-sectional study comprising adolescents (N = 1512) aged 13-18 years (mean age = 15.51 years) was utilized to assess measures on insomnia, depression, anxiety, and stress, IGD, and quality of life during the COVID-19 pandemic.

RESULTS

There were small to large significant relationships between the variables. Psychological distress (i.e., depression, anxiety, and stress) served as a strong mediator in the association between IGD and insomnia and quality of life. IGD directly influenced insomnia and quality of life among the participants.

CONCLUSIONS

IGD is associated with different psychosocial outcomes comprising multiple pathways. Parents need to pay special attention to how much time and how frequently their children play videogames. Parents may need to assist their children in coping with psychological distress during the ongoing COVID-19 pandemic period.

The Mediating Effects of Eating Disorder, Food Addiction, and Insomnia in the Association between Psychological Distress and Being Overweight among Iranian Adolescents

With obesity and excess weight remaining a serious concern worldwide, investigating the mechanisms underlying this is of great importance. Psychological distress is a possible trigger contributing to excess weight for adolescents. Moreover, the association between psychological distress and excess weight may be mediated by eating disorder, food addiction, and insomnia. The present study utilized parallel mediation analysis to assess the aforementioned associations and possible mediation effects among Iranian adolescents. Through stratified and clustered sampling, adolescents (N = 861; mean ± SD age = 15.9 ± 3.2; 372 males) participated and were followed for a one-year period. Excess weight (standardized body mass index, z-BMI); psychological distress (Depression, Anxiety, and Stress Scale-21); eating disorder attitudes (Eating Attitude Test-26); food addiction (Yale Food Addiction Scale for Children); and insomnia (Insomnia Severity Index) were assessed. Eating disorder attitudes, food addiction, and insomnia were significant mediators in the association of psychological distress and z-BMI. Additionally, psychological distress had direct effects on z-BMI. Given that eating disorder attitudes, food addiction, and insomnia showed mediated effects in the temporal association of psychological distress and excess weight, healthcare providers are encouraged to design programs on improving these three mediators to help adolescents overcome excess weight problems.

Mediated effects of eating disturbances in the association of perceived weight stigma and emotional distress

PURPOSE

This study aimed to examine the relationships between perceived weight stigma, eating disturbances, and emotional distress across individuals with different self-perceived weight status.

METHODS

University students from Hong Kong (n = 400) and Taiwan (n = 307) participated in this study and completed several questionnaires: Perceived Weight Stigma questionnaire; Three-factor Eating Questionnaire; Hospital Anxiety and Depression Scale. Each participant self-reported their height, weight, and self-perceived weight status.

RESULTS

After controlling for demographics, perceived weight stigma was associated with eating disturbances (β = 0.223, p < 0.001), depression (β = 0.143, p < 0.001), and anxiety (β = 0.193, p < 0.001); and eating disturbances was associated with depression (β = 0.147, p < 0.001) and anxiety (β = 0.300, p < 0.001) in the whole sample. Additionally, eating disturbances mediated the association between perceived weight stigma and emotional distress. Similar findings were shown in the subsamples who perceived themselves as higher weight or normal weight and in the male and female subsamples. However, in the subsamples who perceived themselves as lower weight, only the links between eating disturbances and emotional distress were significant.

CONCLUSION

Perceived weight stigma was associated with eating disturbances and emotional distress in young adults with both higher and normal weight. Eating disturbances were associated with emotional distress regardless of participants' weight status.

Self and parent-proxy rated health-related quality of life (HRQoL) in youth with obesity: are parents good surrogates?

PURPOSE

Consideration of health-related quality of life (HRQoL) and wellbeing outcomes is important to guide healthcare services for youth with obesity, yet youth perspectives may differ from their parents. This study compared youth and parental HRQoL reports and evaluated levels of concordance across HRQoL domains and as a function of youth age, youth gender and parent informant (mother and father).

METHODS

376 youths with obesity, recruited from community (N = 223) and hospital settings (N = 153), and their parents (N = 190 mothers; N = 91 fathers), completed the PedsQL. Parental and youth agreement across subgroup dyads (mother; father; child gender; child age) were evaluated using Wilcoxon signed-rank test, intra-correlations coefficients (ICCs) and Bland-Altman plots.

RESULTS

Compared to norms, HRQoL levels (youth self-report and parental proxy reports) were lower in all domains. Both mother and fathers' HRQoL reports were significantly lower than youths, most notably in physical HRQoL. Youth-parent concordance ranged from poor to moderate (ICC = 0.230-0.618), with lowest agreement for Physical HRQOL. Mothers were better proxies with ICCs being significant in all domains. Youth-father ICCs were significant only for Social (ICC = 0.428) and School (ICC = 0.303) domains. Girl-mother agreement was significant across all domains, while girl-father agreement was significant only in the Social domain (ICC = 0.653). Both mothers and fathers were poor raters for boys, and younger youths (aged ≤ 12), with non-significant ICCs in most HRQoL domains.

CONCLUSIONS

Parents are poor surrogates for youth HRQoL. Clinicians should be cognizant that parents are not necessarily accurate proxies for youths, and exercise caution when interpreting parent-proxy scores.

The Predictive Relationship of Health Related Quality of Life on Objectively-Measured Sleep in Children: A Comparison Across BMI Ranges

Sleep is considered a major factor related to children's general quality of life with regards to their health outcomes, general well-being, and daily life functions. Kid-KINDL, a health-related quality of life (HRQOL) measure, was used in a consecutive 12-week longitudinal study to compare the association between children's quality of life (QoL) and sleep duration across different BMI ranges. To reduce recall bias, each child wore an electronic pedometer on their wrist to record their sleep duration. The Pearson χ2 test, one-way analysis of variance (ANOVA), and mixed effect repeated measures analysis was used to investigate the association between children's QoL and their sleep duration. The original QoL scores showed that underweight children had lower emotional, family relationship, friendship, and school-related scores, and that overweight children had lower physical satisfaction and self-esteem scores. Emotional (beta = -0.3, p < 0.01) and family relationships (beta = 0.20, p = 0.01) significantly influenced the sleep duration of underweight children. The score of emotional well-being decreased by 0.3, while sleep duration increased by an hour. The poorer the emotional well-being of children, the longer they slept. The score of family well-being increased by 0.2, while sleep duration increased by an hour. The better family quality children had, the longer they slept; For overweight children, the score of family well-being increased by 0.08, while sleep duration increased by an hour (beta = 0.08, p = 0.04). Their sleep got longer when they had better family quality. Physical and school satisfaction scores also significantly affected the sleep duration of obese children. When the score of physical and school increased by 0.09, the sleep duration increases by an hour (beta = 0.09, p = 0.01; beta = 0.09, p < 0.01, respectively). The better the quality of physical condition and school life was, the longer sleep they would get. This study might be the first longitudinal study to evaluate the relationship between QoL and sleep duration, using an objective device but subjective questionnaires, across BMI ranges in a pediatric population.

Attitudes toward and beliefs about obese persons across Hong Kong and Taiwan: wording effects and measurement invariance

Background

The psychosocial consequences of obesity are important but often underrated. The Attitudes Toward Obese Persons (ATOP) and Beliefs About Obese Persons (BAOP) scales used to measure weight-related bias have little psychometric information, especially in East Asian contexts. The objective of this study was to use rigorous statistical methods to demonstrate the psychometric properties of these two instruments in Hong Kong and Taiwanese college students.

Methods

A convenience sample of 707 students was recruited from the universities in Hong Kong and Taiwan. Several competing confirmatory factor analyses (CFAs) were conducted to confirm the factorial structure of the ATOP and BAOP. The best fit models for the ATOP and BAOP were chosen for the examination of the measurement invariance across subcultures. We then compared configurable models with or without loading and/or intercept constrained before correlating the latent constructs between the best models for the ATOP and BAOP.

Results

The comparison in multiple CFAs found that the model with one factor and two correlated-wording-method factors outperformed the other models for both the ATOP and BOAP. However, the internal consistency was suboptimal (ATOP: α = .56 to .80; BTOP: α = .57 to .65) and the measurement invariance was somewhat unsupported among the Hong Kong and Taiwan samples. Moreover, after controlling wording effects, the latent construct of the ATOP was moderately associated with that of BAOP (r = .356; p < .001).

Conclusion

Chinese versions of the ATOP and BAOP can be treated as a unidimensional factor for use in Hong Kong and Taiwan university students. However, further refinements of both instruments may be needed before using them to capture the social attitudes and beliefs toward obesity individuals, which is expected to advance our understanding of weight-related bias in East Asian contexts.

The relationship between children's overweight and quality of life: A comparison of Sizing Me Up, PedsQL and Kid-KINDL

Background/Objective: Overweight and obese children are likely to encounter negative impact on psychological well-being and quality of life (QoL). Hence, for overweight and obese children, measuring QoL could go beyond simply assessing objective medical parameters and cover their physical health, psychological well-being, and social interaction. Generic (Kid-KINDL and Pediatric Quality of Life Inventory [PedsQL]) and weight-related (Sizing Me Up) measures are two major types of QoL measurement instruments; however, little is known about the differences between them. Method: We recruited 569 3rd to 6th graders from eleven schools in Southern Taiwan. In addition to the three QoL questionnaires, the Child Depression Inventory and Rosenberg Self-Esteem Scale were applied. Results: Depression had significantly negative associations with all three QoL questionnaires. Self-esteem was only associated with Kid-KINDL. Body mass index had a significantly stronger relationship with Sizing Me Up than its relationships with PedsQL and Kid-KINDL. In other words, the items related to body size concerns in Size Me Up significantly contributed to impaired overweight/obese children’s QoL. Conclusions: The study further identified the characters and strength of these QoL measures for better suggestions on evaluating physical and psychological issues for overweight/obese children.

Metabolic correlates of health-related quality of life among overweight and obese adolescents

BACKGROUND

Little is known about the metabolic factors associated with the health-related quality of life (HRQOL) among obese youths. The aim of this study is to assess metabolic correlates of HRQOL in a clinical sample of Taiwanese overweight and obese (OW/OB) adolescents.

METHODS

OW/OB adolescents (age 11-19 years) were recruited and compared to their normal-weight counterparts in a tertiary hospital. HRQOL was assessed by the Pediatric Quality of Life Inventory (PedsQL). Student t tests and Cohen's d were used to compare the differences in the PedsQL scores between normal-weight and OW/OB participants who were stratified by their cumulative number of cardiometabolic risk factors (CRF). Pearson's correlation and multivariate linear regression analyses were applied to identify predictors of PedsQL.

RESULTS

OW/OB adolescents (n = 60) reported lower PedsQL scores than those of normal-weight peers. The negative effects were even larger in OW/OB participants with more than one CRF. Body mass index z-scores and serum alanine aminotransferase (ALT) levels were negatively correlated with overall and subscales of PedsQL (r = - 0.283 to - 0.431). Multivariate linear models showed ALT to be the most salient factor associated with poor obesity-related HRQOL.

CONCLUSION

Taiwanese OW/OB adolescents, particularly those having additional CRF, reported worse HRQOL. Impaired liver functions may predispose OW/OB subjects to even worse HRQOL.

The self-reported quality of life of Lithuanian children with asthma was comparable to Western populations

AIM

Quality of life (QoL) has been widely researched among children with asthma in Western countries, but there is a lack of data from eastern Europe, where the prevalence is relatively low, but hospital admission rates are higher. We evaluated the overall level and major determinants of QoL in Lithuanian children aged 5-11 years with asthma.

METHODS

This study was carried out in six asthma outpatient clinics in the two largest cities of Lithuania from January 2015 to July 2016. The children's QoL was measured using the Pediatric Quality of Life Inventory (PedsQL) asthma module, which was completed by the child and one parent.

RESULTS

We collected questionnaires from 226 children (68% boys) with a mean age of eight (±2) years: 65% had mild asthma, 31% had moderate asthma and 4% had severe asthma. One in 10 had been hospitalised in the preceding 6 months. The mean self-reported QoL score was 74 and the parent-reported QoL score was 73. QoL was associated with asthma severity and control, shortness of breath and the child's general health, but not socioeconomic factors.

CONCLUSION

The overall level and major determinants of QoL in children with asthma in Lithuania were comparable with Western populations.

Validating Sizing Them Up: A parent-proxy weight-related quality-of-life measure, with community-based children

Background/Objective: A weight-related Quality of Life (QoL) questionnaire elicits parents' perceptions to understand the impacts of weight on children's QoL. Sizing Them Up, a parent-proxy of a weight-related instrument, is a proper measure for the purpose, but its psychometric properties have not been validated on a non-clinical child population. This study aimed to thoroughly examine the psychometric properties of the Sizing Them Up on a non-clinical child population. Methods: Children from Taiwan (M age  = 11; SD = 1.02; N = 236) filled out a weight-related QoL instrument (Sizing Me Up) while their parents completed Sizing Them Up and two generic QoL instruments. Confirmatory factor analysis (CFA), concurrent validity, and known-group validity were conducted. Results: CFA supported the factor structure of Sizing Them Up. The concurrent validity of the Sizing Them Up total score was satisfactory: r = .46 to .53 with other QoL instruments. Known-group validity was supported as obese children had significantly lower Sizing Them Up total score than did normal-weight and underweight children. Conclusions: We extended the use of Sizing Them Up from clinically obese children to a community-based sample of underweight as well as overweight children. Healthcare providers may use Sizing Them Up to measure the weight-related QoL for children.

Cardiometabolic Risk Factors and Health-Related Quality of Life in Adolescents with Obesity

BACKGROUND

A number of research studies have demonstrated a decrease in health-related quality of life (HRQL) measures among obese children. Moreover, the causes of HRQL impairments are not completely clear. Adolescent obesity is oftentimes associated with other cardiometabolic risk factors (CRFs); hence, the aim of our research was to estimate the frequency of CRFs and to determine whether there is an association between CRFs and HRQL scores among obese adolescents.

METHODS

Our research included 92 treatment-seeking obese adolescents (11-17 years), 34 males. We looked at medical records and performed physical examinations, including anthropometry and laboratory evaluations. PedsQL™ 4.0 was used to assess the HRQL score. Logistic regression models were used to identify CRFs associated with worse HRQL scores, both in total and in each domain.

RESULTS

The vast majority (70.6%) of adolescents had at least one CRF in addition to obesity. A cluster of three to four CRFs was found in 23.3% and was associated with males more than with the degree of obesity [odds ratio (OR) 4; confidence interval (95% CI) 1.3-11.6, p = 0.01]. HRQL scores in emotional functioning domain and scores of HRQL total were directly associated with waist circumference Z-score (OR 4.1; 95% CI 1.1-14.9, p = 0.03 and OR 3.4; 95% CI 1-11.6, p = 0.049). Hypertension was associated with worsening HRQL scores in school functioning domain (OR 3.3; 95% CI 1-10.9, p = 0.049).

CONCLUSION

Obesity in adolescents is associated with a high frequency of associated CRFs and decreased HRQL scores. Although CRFs have an influence on reducing adolescents' HRQL, they are not a determining factor.

Raters Interpret Positively and Negatively Worded Items Similarly in a Quality of Life Instrument for Children

Measurement invariance is an important assumption to meaningfully compare children's quality of life (QoL) between different raters (eg, children and parents) and across genders. Moreover, QoL instruments may combine using negatively and positively worded items-a common method to reduce response bias. However, the wording effects may have different levels of impact on different raters and genders. Our aim was to investigate the measurement invariance of Kid-KINDL, a commonly used QoL instrument, across genders and raters and to consider the wording effects simultaneously. Third to sixth graders (208 boys and 235 girls) completed the self-rated Kid-KINDL, and 1 parent each of 241 children completed the parent-rated Kid-KINDL. The wording effects were accounted for by correlated traits-uncorrelated methods model. The measurement invariance was examined using multigroup confirmatory factor analysis. Item loadings and item intercepts were invariant across gender and rater when we simultaneously accounted for the wording effects of Kid-KINDL. Our results suggest that Kid-KINDL could be used to compare QoL across gender and that parent-rated Kid-KINDL could be used to measure children's QoL. Specifically, the invariant factor loadings across child-rated and parent-rated Kid-KINDL suggest that the score weights in each item were the same for both children and parents (ie, the important items identified by the children are the same items identified by the parents). The invariant item intercepts suggest that both children and parents share the same threshold for each item. Based on the results, we tentatively recommend that each score of a parent-rated Kid-KINDL can stand for each child's QoL.

Quality of life in children with Prader Willi Syndrome: Parent and child reports

PURPOSE

The purpose of this study was to evaluate the use of the Peds QL4.0 instrument to assess quality of life (QL) in children with Prader Willi Syndrome (PWS). This study also sought to compare differences in parent and child report as well as between children with PWS and without PWS.

METHODS

Parents and children with PWS (N=44) completed the PedsQL 4.0 instrument. A sub-sample of children completed the Peds QL 4.0 a second time to assess test-retest reliability. A comparison sample of children who were obese but without PWS (N=66) also completed the PedsQL 4.0.

RESULTS

PedsQL 4.0 showed acceptable internal consistency for the child report (αs >0.72) and was acceptable for 4 out of the 6 scales for the parent report (αs >0.66). Test-retest reliability coefficients showed support for the reliability of the instrument (ICCs>0.64). Parents perceived lower QL than children with PWS. Children with PWS also showed lower QL than children without PWS.

CONCLUSIONS

This study provides support for the use of the PedsQL 4.0 instrument in children with PWS. As observed in other populations, parents perceive a lower QL for their children with PWS than the children themselves.

Child-rated versus parent-rated quality of life of community-based obese children across gender and grade

Background

Quality of life (QoL), which can be examined using self-reports or parental reports, might help healthcare providers understand obese children’s subjective well-being in several domains of life. Community-based obese children report their QoL lower than their parents do. However, the differences between child- and parent-reported QoL have neither been tested across gender and grade nor analyzed by item. This study probed the relationship between obesity and QoL item scores in children, and compared child-reported with parent-reported QoL stratified by gender and grade.

Methods

One hundred eighty-seven dyads of 8- to 12-year-old children (60 obese, 127 normal-weight) and their parents were recruited. QoL was assessed using both child- and parent-reported Pediatric Quality of Life Inventory 4.0 (PedsQL) questionnaires.

Results

Regression analyses showed specific difficulties with physical and emotional QoL in third- and fourth-grade obese boys (β = 0.278-0.620), and specific problems with social functioning in fifth- and sixth-grade obese girls (β = 0.337-0.411). Moreover, parents seemed unaware of the specific difficulties that their children faced (β = 0.274-0.435).

Conclusions

Obese children seemed to have their difficulties from third to fifth grade, respectively, and their parents seemed unaware of them. Thus, parents need to be more aware of specific difficulties related to childhood obesity.

Health related quality of life of obese adolescents in Kuwait

Background

Obesity impairs health related quality of life (HRQL) in adolescents, but most evidence in this area has mostly come from western societies. We wanted to test the hypothesis that obesity impairs HRQL in Kuwaiti adolescents, and to test for differences in HRQL assessed by self-report and parent-proxy report.

Methods

In 500 Kuwaiti 10–14 year olds HRQL was assessed using the Peds QL^TM with both adolescent self-reports (n = 500) and parent-proxy reports (n = 374).

Results

Obesity was not significantly associated with HRQL in regression analysis. In a paired comparison of 98 pairs of obese adolescents vs. 98 healthy weight peers, impairment of HRQL reached significance only for physical score (95% CI = −1.5, -9.4), not for psychosocial score or total score. In a paired comparison of parent-proxy vs. self-reports for the obese adolescents, total score (95% CI = −4.9, -10.9), physical score (95% CI = −3.2, -11.0), and psychosocial score (95% CI = −4.2, -10.8) were all significantly lower in the parent reports.

Conclusions

Obesity is not associated with marked impairment of HRQL in adolescents in Kuwait, in contrast to studies in western societies. This may reflect cultural differences in attitudes towards obesity.
