Childhood obesity and its physical and psychological co-morbidities: a systematic review of Australian children and adolescents

Childhood obesity and adolescent follow-up depressive symptoms: exploring a moderated mediation model of body esteem and gender

Obesity is a well-recognized risk factor for adolescent depressive symptoms, but mediating mechanisms of this association have scarcely been studied. This study is unique in examining an indirect pathway of this link via body esteem (BE) prospectively from childhood (8-12 years) to adolescence (13-18 years). In addition, potential gender moderation was examined. This study utilized data from a case-control study comparing 100 children with and without obesity matched on important confounders (age, gender, and socioeconomic status). Our findings provide support for the mediating role of BE in the link between childhood weight status and adolescent depressive symptoms at a 5-year follow-up. This mediation effect did not differ between boys and girls. The findings suggest the relevance of specifically targeting children's BE in preventive intervention programs among children with obesity to prevent future mental health problems.

Meeting 24-h movement behavior guidelines is associated with academic engagement, social-emotional functioning in obese/overweight youth

BACKGROUND

The 24-h movement behavior (24-HMB) guidelines suggest that the integration of adequate sleep (SL), increased physical activity (PA), and limited screen time (ST) has general health benefits. However, associations of meeting integrated guidelines with academic engagement and social-emotional functioning among obese/overweight youth have yet to be fully examined. Thus, we aimed to investigate the associations between meeting 24-HMB guidelines and the above-presented outcome measures among this unique group.

METHODS

In this cross-sectional study, 2800 children and adolescents (youth aged 6-17 years old) that were retrieved from the National Survey of Children's Health (NSCH) were included for data analysis. Exposure of interests included adherence to 24-HMB guideline(s), while indicators of academic engagement and social-emotional functioning were operationalized. Furthermore, multiple logistic regression was conducted while adjusting for social-demographic variables including age, sex, ethnicity, household income, parental education level and mental health status.

RESULTS

The percentages of meeting 24-HMB guidelines varied greatly across different combinations: 1399 participants (49.96 %) met 1 of the 3 guidelines, 580 participants (20.91 %) met 2 guidelines, while only 91 participants (2.94 %) met all 3 guidelines. Meeting integrated guidelines was selectively associated with higher odds of indicators (showing interest/curiosity in learning, caring about school performance, and completing all required homework) of academic engagement. Additionally, Meeting SL + ST guideline (OR = 0.52, 95%CI: 0.29-0.93, p < 00.05) was associated with lower odds of serious difficulty in concentrating, remembering, and making decisions, while meeting ST + SL guideline (OR = 1.67, 95%CI: 1.03-2.69, p < 00.05) was more likely to be good at making and keeping friendships. Furthermore, meeting all 3 guidelines was associated with less argumentative behaviors (OR = 0.58, 95%CI: 0.33-0.99, p < 00.05) and a higher level of resilience (OR = 3.51, 95%CI: 1.88-6.54, p < 00.01), while meeting any two integrated guidelines was associated with a higher level of resilience (OR = 1.72, 95%CI: 1.09-2.71, p < 00.05).

CONCLUSION

Findings have indicated the role of meeting 24-HMB guidelines, especially integrated guidelines in the healthy development of obese/overweight youth. Policymakers should implement a long-term plan for this unique group to engage in physical activity, achieve enough sleep, and limit screen time.

Trajectories of Sugar-Sweetened Beverage Intake in Early Life: Evidence from a Birth Cohort Study

Infancy and early childhood are periods of dietary transition. Early exposure to specific foods and the establishment of dietary habits during this period can shape long-term food preferences and have lasting effects on health. This study aimed to examine the longitudinal trajectories of sugar-sweetened beverage (SSB) intake in Australian children from birth to age 3 years and identify early-life and socioeconomic factors influencing those trajectories. Mother-infant dyads (n = 934) from the Healthy Smiles Healthy Kids birth cohort study were interviewed on their weekly frequency of SSB intake at 4-month, 8-month, 1-year, 2-year, and 3-year age points. Group-based trajectory modelling analysis was performed to identify trajectories for SSB intake among Australian children. A multivariable logistic regression was performed to identify the maternal and child-related predictors of resulting trajectories. The intake of SSBs showed two distinct quadratic trajectories (high and low) with age. While the two trajectories remained distinctive throughout, the SSB consumption for both groups consistently increased between 4 months and 2 years of age and subsequently stabilised. Compared to low SSB consumers (75%), the high SSB consumers (25%) were significantly more likely to be living in households with three or more children (relative risk (RR): 1.59, 95%CI: 1.02-2.48), had low maternal education (left school < year 12-RR: 1.75, 95%CI: 1.09-2.81; completed year 12-RR: 1.57, 95%CI: 1.02-2.81), and resided in highly/the most socioeconomically disadvantaged areas (highly disadvantaged-RR: 1.89, 95%CI: 1.13-3.18; most disadvantaged-RR: 2.06, 95%CI: 1.25-3.38). Children's SSB intake patterns are established early in life as they transition from infancy to preschool age, and the trajectories of intake established during early childhood are strongly influenced by socioeconomic factors. Hence, interventions targeted to limit SSB intake and improve nutrition amongst children should occur in early life.

Paediatric obesity diagnosis and intervention practices in Australian hospitals - Australia-wide survey

AIM

Previous studies suggest a lack of a unified approach in identifying and addressing children with obesity while being inpatients in individual Australian hospitals. Our study aimed to describe current clinical practice across Australia and identify discrepancies that can aid in developing a more unified response to children identified with obesity as hospital inpatients.

METHODS

A cross-sectional exploratory online survey was distributed to major paediatric in-patient departments in Australia, with a response rate of 68%. Questions focused on education, identification, interventions and attitudes towards a national protocol.

RESULTS

Twenty percent of respondents indicated that staff in their department regularly record body mass index, 66% address weight issues and only 8% consistently refer to appropriate outpatient services. Although 88% of respondents believe that a national protocol for addressing paediatric obesity would be beneficial, respondents emphasised concerns regarding their local resources.

CONCLUSION

Our study can inform the development of a guideline for a unified response to opportunistically identify children with overweight and obesity as inpatients.

Self-Perception Profile, Body Image Perception and Satisfaction in Relation to Body Mass Index: An Investigation in a Sample of Adolescents from the Campania Region, Italy

(1) Background: Body image dissatisfaction has been commonly reported in adolescents with overweight/obesity and has been related to a lack of motivation to change lifestyle behaviors. Plus, a better perception of physical fitness has been related to a higher self-perception in physical aspect and social items in youths. (2) Methods: A total of 120 (59.2% males, mean age of 12.3 ± 0.9 years) middle-school adolescents participated in the present study. Anthropometric measurements were assessed following the standard procedures. Body weight perception and body image satisfaction were assessed using the Silhouette Figure Body Images Test. Self-perception profile, perceived physical fitness, and perceived difficulties in conducting physical tasks were assessed by using structured questionnaires. (3) Results: Overweight was present in 27.5% adolescents and obesity in 32.5%. A total of 89.7% of adolescents with obesity did not have a real perception of his/her weight status and 84.6% of adolescents with obesity were not satisfied with his/her body image. The self-perception of physical appearance, perceived difficulties in running, perceived overall fitness, and perceived speed/agility were lower in adolescents who were unsatisfied with their body image. Body image satisfaction was positively associated with the self-perception of physical appearance and overall fitness and negatively associated with perceived difficulties in running, independently of sex, age, and BMI. (4) Conclusions: Adolescents with obesity did not have a real perception of their weight status and were unsatisfied with their body image. The positive association between body satisfaction, a better perception of overall fitness, and less difficulties in conducting physical tasks suggests the protective role of the components of physical activity and health-related fitness on body acceptance in a critical period of life.

Mental health and BMI in children and adolescents during one year in obesity treatment

BACKGROUND

Mental health plays a major role in children and adolescents with obesity. The aim of this study was (1) to compare mental health in children with obesity with the background population and (2) to investigate if mental health changed during one year in an obesity treatment program.

METHODS

Data on self-reported mental health was collected in 107 children and adolescents (mean age 13.2 years) with obesity at first visit in an obesity treatment program and at one year follow-up (n = 47). Mental health was assessed by eight questions from the Danish Health Behaviour in School-aged Children (HBSC) questionnaire: (1) self-rated health (2) life satisfaction (3) feeling low (4) body-image (5) loneliness (6) self-esteem (7) self-efficacy and (8) social competence. Data was compared to a reference population based on HBSC data. BMI-SDS was based on Danish reference values.

RESULTS

Children and adolescents with obesity had significantly higher odds of reporting negative body image and feeling low and lower odds of reporting high self-rated health and high self-esteem compared to a reference population. There was no difference between the groups regarding life-satisfaction, social competence, self-efficacy or feeling lonely. There were no significant changes in mental health from first visit to one-year follow-up.

CONCLUSION

Our findings highlight the mental health difficulties in children and adolescents with obesity, and the importance of addressing these issues in obesity treatment. The results also indicate that children with obesity have psychosocial resources that should be exploited in treatment protocols.

Effect of physical activity on anxiety, depression and obesity index in children and adolescents with obesity: A meta-analysis

FOR FULL-LENGTH ARTICLES

This study systematically identified the effects of physical activity (PA) on depression, anxiety and weight-related outcomes among children and adolescents with overweight/obesity. EMBASE, The Cochrane Library, Web of Science, and PubMed were searched from January 1, 2000 to August 1, 2022 for peer-reviewed papers. Meta-analyses were conducted to ascertain the effect of physical activity on symptoms of anxiety, depression and weight-related outcomes in overweight/obese children and adolescents. Twenty-five studies representing 2188 participants, with median age 12.08 years old (8.3 to 18.44 years) were included. Depressive and anxiety symptoms, BMI, BMI z-scores, weight, waist circumference and height were evaluated. After incorporating the effects of PA interventions on children and adolescents with overweight/obesity, PA could improve depressive and anxiety symptoms, but not obesity indexes except waist circumference. While, PA combined with other interventions have a significant effect both on anxiety symptoms and BMI compared to pure PA intervention. In terms of intervention duration, we observed that durations falling within the range of 8 to 24 weeks exhibited the most positive effects on reducing depressive symptoms.

FOR SHORT COMMUNICATIONS

We included 25 articles on the effects of physical activity on psychological states such as depression and anxiety, weight, BMI and other weight-related indicators in children and adolescents with overweight/obesity. We attempted to determine the most appropriate type of physical activity intervention for children and adolescents with overweight/obesity, as well as the most appropriate population characteristics and duration by combining the outcome data from each article. This has a great enlightening effect for health workers to carry out corresponding strategies in the future.

Long-term changes in eating-related problems and quality of life in children with overweight and obesity attending a 10-week lifestyle camp

BACKGROUND

Eating-related problems (e.g., binge eating (BE)) and impaired quality of life (QoL) is more prevalent in children with overweight and obesity. This study aimed to investigate changes in self-reported overeating (OE), BE, and QoL in children with overweight or obesity attending multicomponent 10-week lifestyle camps with a 52-weeks follow-up. Additionally, the study sought to investigate whether self-reported OE/BE before camp was associated with changes in QoL.

METHODS

Children aged 7 to 14-years could attend camp if they had overweight/obesity, were lonely, unhappy, or had social or family-related problems. In this study only children with overweight and obesity were included (n:185). OE, BE, and QoL were measured using self-reported questionnaires.

RESULTS

In total, 38 % of the children reported regular BE at baseline. Regular OE, occasional BE, and occasional OE was reported by 14 %, 13 %, and 11 %, respectively, while 24 % reported no eating-related problems. The relative risk of experiencing eating-related problems decreased at 10-weeks compared to baseline. Additionally, the probability of regular OE (RR 0.12 (95 % CI 0.04;0.38) (X2 = 8.44, p = 0.004)) and regular BE (RR 0.01 (95 % CI 0.00;0.11) (X2 = 9.91, p = 0.002)) remained lower at 52-weeks relative to baseline. All QoL dimensions improved after camp, and the presence of self-reported OE and regular BE at baseline was significantly associated with lower QoL at baseline, 10 and 52-weeks.

CONCLUSION

Children self-reporting OE and BE may be a particular vulnerable group that needs more support from camp staff and healthcare professionals to improve QoL.

Physical activity level correlates with obesity-related factors, but not with fundamental movement skills in preschool children: a cross-sectional study

This study aimed to examine the differences in physical activity (PA) level, fundamental movement skill (FMS), and obesity-related factors in preschoolers. A cross-sectional study was conducted in 426 preschool children aged 3-5 years. Participants were assigned to the low PA group (LPAG), moderate PA group (MPAG), and high PA group (HPAG) according to the total score obtained in the PA questionnaire for young children. FMS and obesity-related factors were also analyzed. PA was compared by age and sex, and FMS and obesity-related factors were compared between groups. Significant differences were found according to sex. Boys were more active than girls in the 3-4 years age group, but no significant differences were observed at the age of 5 years. LPAG showed lower FMS than MPAG and HPAG, although this was not statistically significant. However, body mass index (BMI), BMI z-score, body fat, and muscle mass showed significant differences in terms of PA levels. Consideration of age and sex is crucial in promoting PA among preschoolers. Additionally, better obesity-related factors are associated with higher PA levels, and FMS may be a useful tool in evaluating health and fitness.

The temporal stability of maternal parenting style and child feeding practices: A six-wave longitudinal study

Although parenting styles and child feeding practices are conceptualized as distal, static predictors of child eating and weight outcomes, few studies have examined the temporal stability (i.e., change over time) of these parenting measures. Also, parental characteristics, such as mental health or socio-demographics, may make it more or less difficult to sustain consistent parenting behavior. This study examined the temporal stability of parenting styles and child feeding practices and the association between temporal stability indices with maternal sociodemographic and mental health characteristics. The analytic sample included 161 ethnically diverse mothers enrolled in a six-wave bi-annual longitudinal study. During each wave, mothers reported on their parenting styles and child feeding practices using validated self-report questionnaires. Temporal stability indices for parenting styles were moderate for authoritative (ICC = 0.57) and authoritarian (ICC = 0.70) styles, yet high for permissive (ICC = 0.78) styles. Temporal stability scores for child feeding practices were low for discipline (ICC = 0.33), limit setting (ICC = 0.33), monitoring (ICC = 0.36), and pressure to eat (ICC = 0.34); however, restriction (ICC = 0.53) and role modeling of healthy eating were moderate (ICC = 0.73). Greater income and education status were positively associated with stability in authoritative, authoritarian, and permissive parenting styles, as well as with limit setting, monitoring, role modeling of healthy eating, and pressure to eat feeding practices. Higher anxiety and depressive symptoms and lower self-esteem were negatively associated with permissive parenting styles and role modeling of healthy eating. Findings show that maternal parenting styles and child feeding practices fluctuate over time, and sociodemographic and mental health characteristics are related to stability of some of these parenting styles and behaviors.

Efficacy of eHealth interventions to reduce depression symptoms in individuals with obesity: a systematic review of randomized controlled trials

Introduction

Obesity and depression are inter-related health concerns, demanding a high level of treatment and costs in the health care system. The development of eHealth interventions that simultaneously address obesity and mental health can be supportive in this regard. However, evidence of the efficacy of eHealth interventions in the treatment of depression symptoms in individuals with obesity is lacking. The aim of this systematic literature review is to evaluate the efficacy of existing eHealth interventions for individuals with obesity that target depression symptoms.

Methods

We systematically searched electronic databases (Cochrane Library, PubMed, Scopus) to identify studies published in English between January 2016 and January 2023, that focused on eHealth interventions, targeting depression symptoms in individuals with obesity people. Exclusion criteria were study objectives that (1) focused specifically on one or more metabolic comorbidities of individuals with obesity, e.g., hypertension, hyperlipidemia, diabetes; (2) focused specifically on eating disorders comorbidities e.g., binge eating disorder, and (3) focused specifically on patients before or after bariatric surgery.

Results

The database search identified 214 records. Six articles were included in this review. Sample sizes ranged from 70 to 1267 participants of ages 18-60 years. All included studies were randomized controlled trials. Two of the six included studies were web-based interventions guided either by medical doctors or psychologists. All interventions included video, printed materials, and interactive parts of which two studies integrated elements of Cognitive Behavioural Therapy and Social Cognitive Therapy. The findings showed that eHealth treatment services, supported and guided throughout the intervention had high acceptance and efficacy in the reduction of depression symptoms among individuals with obesity.

Conclusion

EHealth interventions that address and target both mental and physical health with interactive strategies calls for better efficacy in the reduction of depression symptoms. Future eHealth interventions that target depression symptoms in individuals with obesity should integrate digital strategies that address both mental and physical health through interactive modules.

Mediation of the association between social environmental characteristics of family childcare home and weight status in children by diet quality

BACKGROUND

The food and beverages served in family childcare homes (FCCHs) may play an important role in the development of childhood overweight and obesity. This analysis examines whether children's diet quality mediates the relationship between foods and beverages served in FCCHs and preschool-aged children's weight status.

METHODS

Trained and certified staff conducted observations for two days in each FCCH, using the Environment and Policy Assessment and Observation (EPAO) measure to determine the foods and beverages served to children (N = 370) in FCCHs (N = 120). They also used the Dietary Observation in Child Care (DOCC) protocol to assess children's food and beverage intake during childcare, from which we calculated the Healthy Eating Index-2015 (HEI), a measure of diet quality. Height and weight were measured for each child with parent consent from which the child's body mass index (BMI) z-scores were calculated. A multilevel mediation analysis was conducted to indicate whether children's diet quality mediates the relations between food and beverage served in FCCHs and preschool-aged children's weight status.

RESULTS

Children's total HEI scores significantly mediated the relationship between the EPAO subscale Food Provided and children's BMI z-scores (B=-0.01, p < .05, 95% CI = [-0.03, - 0.002]). Further, the EPAO subscale Food Provided was positively associated with the total HEI score (B = 0.75, p < .01, 95% CI = [0.32, 1.18]). Total HEI scores were negatively associated with BMI z-score (B=-0.01, p < .05, 95% CI = [-0.02, - 0.001]).

CONCLUSION

Children's diet quality did significantly mediate the relationship between the food served in FCCHs and children's weight status. More longitudinal studies with longer follow-up periods need to be conducted to confirm these relationships. Further, future studies need to examine the relationships between a broader spectrum of FCCH environmental characteristics and home environment with children's weight status, as well as other mediators including physical activity.

A Review of the Role of Built Environment and Temperature in the Development of Childhood Obesity

The burden of obesity is rising globally and is studied widely, yet the evidence for the association of environmental factors (both built and natural) with childhood obesity remains inconsistent. A relation with temperature as a proxy for natural environmental factors for obesity has not been reviewed previously. The purpose of this review was to assimilate updated evidence on environmental factors of childhood obesity. Three databases, MEDLINE (Medical Literature Analysis and Retrieval System Online), Web of Science, and Cochrane, were searched for articles related to the effect of built environment and temperature on childhood obesity in 6-12-year-olds published in the last five years. Twelve studies were identified: four longitudinal and eight cross-sectional. The studies were appraised using the National Institute of Health Quality (NIH) Assessment Tool. A review of included studies showed that built environmental features like higher residential and population density, higher intersection density, more playgrounds, and all park features like the presence or availability of parks, high number of parks, proximity to parks, and an increased park land area, showed a protective association against childhood obesity while land use mix showed a promoting association for the development of childhood obesity. Inconclusive evidence was observed for other built environmental features. The search strategy did not retrieve any literature published in the past five years studying the association between temperature and the development of childhood obesity. Standardization of definitions of exposure and outcome measures is recommended. Further research studying the relationship between environmental temperature and the development of childhood obesity is recommended.

Effect of a Multifaceted Intervention on Children's Body Image and the Mediating Role of Body Image in Changes in Adiposity Indicators

Besides genetic factors and energy-related behaviors, psycho-cultural factors are also important in obesity etiology. Previous studies have suggested that improving body image might be an effective method for managing body weight. Thus, this study aimed to evaluate the effects of a multifaceted intervention on the body image of children and explore whether body image played a mediating role in changes in adiposity indicators. This study was embedded in a cluster randomized controlled trial, involving 1287 children from 24 primary schools in three cities in China (Beijing, Changzhi and Urumqi). The 9-month multifaceted intervention on childhood obesity included five components (three targeted children and two targeted environments), and randomization was performed by an independent person who was blinded to the schools. Two indicators (body size perception and body size expectation) were chosen to characterize body image and were measured by Ma figural stimuli at baseline and the end of the trial. Changes in body image indicators were classified as conducive to weight loss or not. Other anthropometric measures and self-reported behaviors were also collected at both time points. Generalized linear mixed models were used in the analyses. Compared to the controls (n = 648), the proportion of body size perception conducive to weight loss increased in the intervention group (n = 639), with an odds ratio of 2.42 (95%CI: 1.70~3.45, p < 0.001). The proportion of body size expectation conducive to weight loss also increased more in the intervention group than in the controls (OR = 1.74, 95%CI: 1.14~2.66, p = 0.010). In children whose baseline nutritional status was "normal weight with higher BMI" or "overweight/obese", the improvements in body size perception and body size expectation partly mediated the association between the intervention and changes in BMI, BMI Z score, waist circumference and body fat percentage (p < 0.05). This multifaceted study effectively improved the body image of children, which, in turn, led to beneficial changes in adiposity indicators. For the first time, body size perception and body size expectation have been confirmed to be important factors associated with the beneficial effect of a childhood obesity intervention, suggesting that body image components should be generalized in the future.

Paths towards a healthier BMI among short and adequate sleepers: A pathway network analysis considering movement behaviors in low-income preschoolers

INTRODUCTION

Short sleep duration has been seen as a predictor of higher body mass index (BMI) in youth. Sleep duration varies substantially along early childhood, and the paths towards a healthier BMI, considering the other movement behaviors (physical activity-PA and screen time) are unexplored in preschoolers.

AIM

To construct a sleep-BMI model to capture the direct and indirect paths to intervening towards a healthier BMI, according to low-income preschoolers' compliance with the other movement behaviors.

METHODS

Two hundred and seventy two preschoolers (4.5 ± 0.0; 138 boys) participated in the study. Sleep and screen time (ST) were assessed in a face-to-face interview with primary caregivers. PA was assessed using accelerometer (wGT3X-BT). Preschoolers were categorized as compliant or not with sleep, screen time, total and moderate to vigorous PA recommendations. BMIz-score was calculated according to preschoolers' sex and age. All the assessed variables, besides sex and age were included in a Network Pathway Analysis (NPA) according to age as nodes.

RESULTS

At 3 years old, a direct and negative path between sleep-BMIz score was observed. At four and 5 years old, this relationship became positive. Further, girls were more compliant with sleep, ST and total PA recommendations. Total PA (TPA) showed the highest expected influence value in the general, 3 and 4 years old NPA.

CONCLUSION

The NPA analysis showed different directions for the relationship between sleep and BMIz score, according to age. Intervention strategies to a healthier BMI among preschoolers compliant or not with sleep recommendations should focus in increasing TPA.

The skeletal and dental age advancements of children and adolescents with overweight and obesity: A systematic review and meta-analysis

INTRODUCTION

Over the past decades, a trend of increasing obesity among children has emerged. This study aimed to evaluate and summarize the impacts of overweight and obesity on children's and adolescents' skeletal and dental developmental advancement that may influence orthodontic management.

METHODS

Registered with the Prospective Register of Systematic Reviews (registration no. CRD42022347488), this study complies with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Particularly, relevant original studies on skeletal or dental age evaluation were screened from accessible electronic databases and supplemented by hand-searching. Meta-analysis was recruited to calculate differences (and their 95% confidence interval [CI]) between subjects with overweight or obese and normal-weight counterparts.

RESULTS

After applying the inclusion and exclusion criteria, 17 articles were selected for the final review. Two of the 17 selected studies were found to have a high risk of bias and moderate the other 15. A meta-analysis detected no statistically significant difference in skeletal age between children and adolescents with overweight and normal-weight counterparts (P = 0.24). However, the dental age of children and adolescents with overweight was found to be 0.49 years (95% CI, 0.29-0.70) advanced in comparison with normal-weight counterparts (P <0.00001). In contrast, children and adolescents with obesity were found to have advanced skeletal age by 1.17 (95% CI, 0.48-1.86) years (P = 0.0009) and dental age by 0.56 (95% CI, 0.37-0.76) years (P <0.00001) compared with their normal-weight counterparts.

CONCLUSION

Because the orthopedic outcomes of the orthodontic intervention are closely tied to the skeletal age of the patients, these results suggest that the orthodontic evaluation and treatment of children and adolescents with obesity might occur earlier than that of the normal-weight population.

The influence of immigrant background and parental education on overweight and obesity in 8-year-old children in Norway

BACKGROUND

Little is known about the prevalence of overweight/obesity and socio-economic position (SEP) in children with immigrant background in Scandinavia. The purpose of this study is to examine the prevalence of overweight/obesity by immigrant background among children in Norway and to explore the role of SEP in explaining differences in weight status.

METHODS

Anthropometric data from 8,858 children (age 8.3 years) from the population-based Norwegian Childhood Growth Study were used. Information about immigrant background, country of origin, and parental education (used as an indicator of SEP) were provided by Statistics Norway. For children with immigrant background, regional background was determined based on country of origin. Prevalence ratios (PR) were estimated for overweight/obesity and weight-to-height-ratio (WHtR) ≥ 0.5 by immigration and regional background, using generalized estimating equation log-binominal models adjusting for sex, age, survey year (model 1), residential area, population density (model 2) and parental education (model 3).

RESULTS

Children with immigrant background had a higher prevalence of overweight/obesity and WHtR ≥ 0.5 than non-immigrant background children. Adjusted for parental education, children with an immigrant background from Southern and Eastern Europe, Asia except South-Asia, and Africa had a higher prevalence of overweight/obesity [PR: 1.37 (95% confidence interval (CI): 1.10-1.72), 1.28 (1.05-1.57), 1.47 (1.13-1.91), respectively] than children with a non-immigrant background. Children originating from Asia except South-Asia had a higher prevalence of WHtR ≥ 0.5 (PR: 1.64, CI: 1.25-2.15) compared to non-immigrant background children. The adjustment for parental education did not substantially change the results.

CONCLUSION

Children with immigrant background had higher prevalence of overweight/obesity than non-immigrant background children. The difference varied according to region of origin but not substantially according to parental education. There is a need for culturally acceptable preventative measures targeting the parents of immigrant background children.

Mediation of the Association between Social Environmental Characteristics of Family Childcare Home and Weight Status in Children by Diet Quality

Background

The food and beverages served in family childcare homes (FCCHs) may play an important role in the development of childhood overweight and obesity. This analysis examines whether children's diet quality mediates the relationship between foods and beverages served in FCCHs and preschool-aged children's weight status.

Methods

Trained and certified staff conducted observations for two days in each FCCH, using the Environment and Policy Assessment and Observation (EPAO) measure to determine the foods and beverages served to children (N=370) in FCCHs (N=120). They also used the Dietary Observation in Child Care (DOCC) protocol to assess children's food and beverage intake during childcare, from which we calculated the Healthy Eating Index-2015 (HEI), a measure of diet quality. Height and weight were measured for each child with parent consent from which the child's body mass index (BMI) z-scores were calculated from. A multilevel mediation analysis was conducted to indicate whether children's diet quality mediates the relations between food and beverage served in FCCHs and preschool-aged children's weight status.

Results

Children's total HEI scores significantly mediated the relationship between the EPAO subscale "Food provided" and children's BMI z-scores (B=-.01, p<.05, 95% CI = [-.03, -.002]). Further, the EPAO subscale "Food provided" was positively associated with the total HEI score (B=.75, p<.01, 95% CI = [.32, 1.18]). Total HEI scores were negatively associated with BMI z-score (B=-.01, p<.05, 95% CI = [-.02, -.001]).

Conclusion

Children's diet quality did significantly mediate the relationship between the food served in FCCHs and children's weight status. More longitudinal studies with longer follow-up periods need to be conducted to confirm these relationships. Further, future studies need to examine the relationships between a broader spectrum of FCCH environmental characteristics and home environment with children's weight status, as well as other mediators including physical activity.

Evaluation of depression, anxiety symptoms, emotion regulation difficulties, and self-esteem in children and adolescents with obesity

OBJECTIVE

Pediatric obesity negatively affects many areas of mental health, especially anxiety and depression. This study aimed to investigate the effects of obesity on anxiety, depression, self-esteem, and emotion regulation in children and adolescents.

METHODS

Our study included 50 children and adolescents aged 11-17 years with a diagnosis of obesity and 48 control participants. The Revised Child Anxiety and Depression Scale (RCADS), Rosenberg Self-Esteem Scale (RSE), Difficulties in Emotion Regulation Scale (DERS), and Piers-Harris Children's Self-Concept Scale 1 (PHCSCS) were administered to all participants.

RESULTS

A significant difference was found between the groups (p < 0.05) in the analysis of the PHCSCS and RCADS total score; the GAD, PD, SOC, and MDD subscale scores; the DERS total score; the Clarity, Impulse, Strategies, Goals subscale scores; and the RSE Self-Esteem subscale. A significant correlation was found between the PHCSCS, RCADS, DERS, and RSE total scores and some subscale scores (p < 0.05).

CONCLUSION

On the basis of the results, it was determined that children and adolescents with obesity had high levels of anxiety and depression symptoms, they had lower self-esteem, and had more difficulties in emotion regulation. Furthermore, those with anxiety and depression symptoms had lower self-esteem, and the children who had problems in emotion regulation also had lower self-esteem. Anxiety, depression, low self-esteem, and difficulties in emotion regulation can negatively affect obesity treatment. Therefore, screening and treatment of these conditions are of great importance.

Examination of relationship factors between psychological resilience and social support in adolescent obesity

PURPOSE

Childhood obesity is one of the most severe public health problems, and psychiatric conditions have been associated with obesity. In this study, we aimed to investigate psychological resilience and possible related factors in adolescents with obesity.

METHOD

The study included 90 adolescents with obesity and 100 healthy adolescents of similar age. Data were collected using a sociodemographic information form, the Child and Youth Resilience Measure-28 (CYRM-28), and the Multidimensional Scale of Perceived Social Support. Scale scores were compared by Pearson's correlation coefficient test with SPSS-23. Multiple linear regression was performed to describe the relationships between variables.

RESULTS

The adolescents participating in the study were similar in terms of age and gender. Psychological resilience and social support in the obesity group were lower than in the control group (p < 0.05). A negative relationship was found between body mass index (BMI) and resilience levels of adolescents with obesity, and a positive relationship was found between social support and resilience levels (p = 0.027 and p < 0.001, respectively). The perceived family and significant other social support subscale scores of adolescents in the obesity group were significantly lower than in the control group (p = 0.037 and p = 0.023, respectively). The most related variable with the CYRM-28 was the level of perceived social support: standardized β = 0.409; t(151) = 5.626; p < 0.001.

CONCLUSION

A higher BMI has a negative effect on psychological resilience, and family support tends to be lower in these cases. New studies are needed to clarify whether this result is one of the causes of obesity or one of its consequences.

Association between Weight Status and Mental Health among Korean Adolescents: A Nationwide Cross-Sectional Study

This study explored the relationship between adolescents’ weight status and mental health problems. It specifically investigated the weight perceptions of obese adolescents and the effect on their mental health. This cross-sectional study was based on the data of adolescents aged 12–18 years from the Korean National Health and Nutritional Examination Survey (2010–2019). Data regarding anthropometric measurements, health conditions, and socioeconomic status were extracted, and the associations between weight status (actual, perceived, or misperceived) and mental health conditions (depressed mood, perceived stress, and suicidal ideation) were analyzed using complex sample multiple logistic regression after adjusting for possible confounders. A total of 5683 adolescents (53.1% boys and 46.9% girls) were included in this study, with a mean age of 15.1 years. Among the participants, actual, perceived, and misperceived status of being overweight were observed in 20.8%, 32.7%, and 18.4%, respectively. Additionally, depressed mood, perceived stress, and suicidal ideation were observed in 9.1%, 25.7%, and 7.4% of Korean adolescents, respectively, with higher prevalences in girls for all three conditions. Actual weight status was not significantly associated with mental health conditions in either sex. Furthermore, girls who perceived themselves to be overweight, regardless of their actual body weight, or who had overestimated their actual weight were more likely to have experienced depressed mood and stress, while boys who perceived themselves to be underweight were more likely to have experienced suicidal ideation than participants with an average weight perception or an accurate recognition of their weight status. Conversely, in overweight/obese participants, perceived weight status was not associated with mental health conditions. In conclusion, perceived weight status and its discrepancy with actual body weight were more strongly associated with an increased risk of mental health problems than actual weight status itself among Korean adolescents. Therefore, adolescents’ perceptions of their body image and weight-related attitude should be assessed to promote their mental health.

Household food insecurity and changes in BMI z-score in a pediatric obesity management clinic

BACKGROUND

Multicomponent lifestyle interventions are fundamental in pediatric obesity management. However, whether household food insecurity influences the efficacy of such interventions remains undocumented.

OBJECTIVE

The objective was to compare changes in body mass index z-score (BMIz) among children whose family received lifestyle counseling at a pediatric obesity management clinic in Montreal (Canada) according to their household food security status.

METHODS

This is a retrospective, longitudinal analysis of medical records of children (2-17 years) with overweight or obesity who received lifestyle counseling at a pediatric obesity management clinic. The number of visits at the clinic and the duration of the follow-up were individualized. Household food security status was assessed using Health Canada's Household Food Security Survey Module at the first visit at the clinic. BMIz was calculated and updated at each visit. A reduction of ≥0.25 in BMIz between the last and the first visit at the clinic was considered clinically meaningful. Statistical significance was considered at P<0.05.

RESULTS

Among the 214 children included in the study, 83 (38.8%) lived in a food insecure household. In multivariable-adjusted analyses, differences in BMIz between the last and the first appointment tended to be smaller among children who lived in a food insecure household compared with those in a food secure household [ΔBMIz_{food insecurity}=-0.432 (95% confidence interval (CI): -0.672, -0.193) vs ΔBMIz_{food security}=-0.556 (95% CI: -0.792, -0.319; P=0.14)]. Differences were most notable in the first 6 months of follow-up. The odds ratio of achieving a clinically significant reduction in BMIz over follow-up associated with household food insecurity, compared with household food security, was 0.57 (95% CI: 0.31, 1.05; P=0.07).

CONCLUSIONS

In this sample of children followed at a pediatric obesity clinic, those who lived in a food insecure household experienced smaller BMIz reductions compared with those who lived in a food secure household.

The interplay between emotion regulation, interpersonal problems and eating symptoms in individuals with obesity: A network analysis study

INTRODUCTION

A complex and bidirectional relationship between eating and psychological symptoms in individuals with obesity has been proposed. This study aims to identify the specific processes playing a role in this association, using a data-driven approach.

METHODS

Two hundred ninety-four adults with obesity, including 106 (36 %) with binge-eating disorder, were consecutively admitted to a specialized public center. They completed self-report questionnaires to assess emotion regulation, interpersonal problems, self-esteem, binge-eating symptoms, and expectancies regarding eating behaviors. To assess the interplay among eating and psychological variables, a network analysis was used. The bridge function analysis was also performed to identify the bridge nodes among three communities (eating symptoms, interpersonal and emotional problems).

RESULTS

The network was stable. Limited access to emotion regulation strategies, eating helps manage negative affect, and non-assertiveness were the nodes with the highest strength centrality. Lack of emotional clarity, non-assertiveness, socially inhibition, and binge-eating were the nodes with the highest bridge strength.

LIMITATIONS

The main limitation of the study is the cross-sectional nature of the findings which prevents to infer causality regarding the association between symptoms in the network.

DISCUSSION

An interplay between eating symptoms and affective and interpersonal factors characterizes individuals with obesity. Across the variety of psychological problems associated with obesity, the present study suggests specific psychological variables and their connections that could be addressed to improve treatment outcome.

Parental Influences on Physical Activity and Screen Time among Preschool Children from Low-Income Families in Brazil

Background: Children from low-middle income countries (LMIC) are disproportionately affected by obesity, and low physical activity (PA) and high screen time (ST) are major contributors. Parents are key influencers on children's PA and ST, yet, no study has investigated relationships between parenting practices and children's PA and ST in LMIC families. This study examined parental influences on PA and ST among preschool-aged children from low-income families in Brazil. Methods: Parents completed a validated, culturally adapted interviewer-administered survey assessing child ST and parenting practices. Child sedentary time, total movement, and energetic play were measured by accelerometery. Results: Data were available on 77 parent-child dyads [mean age 4.6 years (standard deviation = 0.8), 53% male, and 41% mixed-race]. Parenting practices associated with greater PA were use of PA to reward/control behavior (rho = 0.34-0.49), limiting or monitoring ST (rho = 0.30), explicit modeling/enjoyment of PA (rho = 0.24), verbal encouragement for PA (rho = 0.30), and importance and value of PA (rho = 0.24-0.38; p < 0.05). Parenting practices associated with higher ST were rules around active play indoor (rho = 0.23), use of ST to reward/control behavior (rho = 0.30), exposure to screens (rho = 0.40), and explicit modeling/enjoyment of ST (rho = 0.50; p < 0.05). Conclusion: Recognized parenting practices such as explicit modeling of PA and ST, monitoring and limiting ST, and rules and restrictions about PA and ST are associated with young children's PA and ST in low-income Brazilian families. The findings identify potential targets for family-based interventions to promote healthy lifestyle behaviors and prevent childhood obesity.

Impact of Physical Activity-Based Interventions on Children and Adolescents' Physical Self-Concept: A Meta-Analysis

Background: Observational studies associate physical activity (PA) with improved perceptions of children and adolescents' physical self-concept (PSC) and global self-concept (GSC). However, only a few PA-based interventions exist for improving PSC and their results have been inconclusive. Objective: To determine the effect of specific PA-based programmes on the PSC (including its sub-dimensions) and GSC of children and adolescents, and to assess possible moderators. Methods: The databases Web of Science, Scopus, SportDiscus, PubMed, CINAHL, and Cochrane Library were reviewed in February 2020. Only studies with pre-post measurements and control groups were included. The impact of PA-based interventions was explored through different meta-analyses and moderator analyses. Results: Altogether, 20 studies were included in the meta-analysis. Positive and significant effects of PA were determined on self-perceived physical appearance (g = 0.13; 95% CI = 0.03, 0.23), self-perceived sport competence (g = 0.30; 95% CI = 0.09, 0.51), self-perceived physical fitness (g = 0.19; 95% CI = 0.05, 0.32), PSC (g = 0.31; 95% CI = 0.10, 0.52), and GSC (g = 0.17; 95% CI = 0.01, 0.33). The existence of additional interventions in PA-based programmes (e.g., interventions focused on psychological factors or healthy habits) moderated the influence of PA on self-perceived sport competence and physical fitness. Moreover, environment and time were distinguished as moderators for self-perceived physical appearance and sport competence. Further, intervention type, gender, and frequency of intervention moderated the effects of PA on PSC. Conclusions: PA-based interventions, especially in school, seem to be beneficial for the development of positive physical self-perceptions.

Normative Values and Psychometric Properties of EQ-5D-Y-3L in Chilean Youth Population among Different Weight Statuses

BACKGROUND

This study aimed to provide population norms among children and adolescents in Chile using the EQ-5D-Y-3L questionnaire and to examine its feasibility and validity among body weight statuses.

METHODS

This was a cross-sectional study in which 2204 children and adolescents (aged 8-18 years) from Chile completed a set of questionnaires providing sociodemographic, anthropometric and health-related quality of life (HRQoL) data using the five EQ-5D-Y-3L dimensions and its visual analogue scale (EQ-VAS). Descriptive statistics of the five dimensions and the EQ-VAS were categorized into body weight status groups for the EQ-5D-Y-3L population norms. The ceiling effect, feasibility and discriminant/convergent validity of the EQ-5D-Y-3L were tested.

RESULTS

The dimensions of the EQ-5D-Y-3L questionnaire presented more ceiling effects than the EQ-VAS. The validity showed that the EQ-VAS could discriminate among body weight statuses. However, the EQ-5D-Y-3L index (EQ-Index) demonstrated a non-acceptable discriminant validity. Furthermore, both the EQ-Index and the EQ-VAS presented an acceptable concurrent validity among weight statuses.

CONCLUSIONS

The normative values of the EQ-5D-Y-3L indicated its potential use as a reference for future studies. However, the validity of the EQ-5D-Y-3L for comparing the HRQoL among weight statuses could be insufficient.

The Association of Maternal BMI with Overweight among Children Aged 0-59 Months in Kenya: A Nationwide Cross-Sectional Study

Childhood overweight is a growing global public health challenge and is prevalent in many countries. We aimed at exploring the prevalence of childhood overweight and the association of maternal body mass index (BMI), maternal demographic factors, and child-related factors with childhood overweight among Kenyan children aged 0-59 months. This study utilized Kenya's 2014 demographic and health survey, which was based on national representative cross-sectional data. A total of 8316 children and their mothers' data were analyzed. Overweight in children and maternal BMI were defined using WHO standard criteria. Multivariate logistics regression models were used to study the association of maternal BMI and childhood overweight. Nationally 5% of Kenyan children aged 0-59 months are overweight (5.5% male vs. 3.8% female). The highest prevalence in overweight among children was found in Central region (6.9%) and lowest in North Eastern (3.1%) which could be explained by the various economic disparities. Maternal BMI with underweight was associated with lower odds (OR 0.30, 95% CI 0.14-0.64) whereas, overweight and obesity were associated with higher odds of overweight (OR for overweight 1.64, 95% CI 1.28-2.11 and OR for obesity 1.74, 95% CI 1.22-2.47) among their children compared to normal weight mothers. Overweight among children is of great concern and therefore initiatives to tackle both child and maternal health are urgently needed.

Combined high-intensity interval training as an obesity-management strategy for adolescents

Effective and safe exercise protocols for obesity management in adolescents are imperative. This study aimed to analyse compliance, efficacy, and safety of combined high-intensity interval training circuit (HIIT) in the management of obesity (including overweight) in adolescents, compared to traditional training (TT). Data from 55 adolescents (47.3% girls) (TT n = 31; HIIT n = 24), aged 12-18 (mean age of 14.3 ± 1.7), with overweight and obesity (median BMI z-score of 2.95), were assessed at baseline and month 6 (Clinicaltrials.gov/NCT02941770). During the 6-month intervention, participants in both exercise groups attended two exercise sessions/week (60 min/session) along with a set of appointments with a paediatrician, nutritionist, and exercise physiologist. Forty-six participants completed the intervention (TT n = 23; HIIT n = 23). Exercise session attendance (≥80%) was significantly higher among HIIT participants (73.9 vs. 13.0%, p < .001). HIIT, but not TT, showed a significant decrease in BMI z-score (d = 0.40, p < .001), body fat mass (BFM, %) (d = 0.41, p = .001), and trunk fat mass (d = 0.56, p < .001), as well as a significant increase in muscle mass (MM, %) (d = 0.28, p = .001) between baseline and 6 months. According to generalized estimating equations, time-by-attendance interactions (instead of time-by group) were found in BMI z-score (β = 0.25, 95%CI: 0.17, 0.33), BFM (β = 2.29, 95%CI: 1.02, 3.56), trunk fat mass (β = 2.94, 95%CI: 1.70, 4.18), and MM (β = -1.16, 95%CI: -1.87, -0.45). No adverse events were reported during HIIT sessions. Although compliance may mediate the impact of an exercise protocol on health-related outcomes, HIIT showed to be safe, with higher compliance compared to TT, which may result in improved outcomes overtime.

Associations between trajectories of obesity prevalence in English primary school children and the UK soft drinks industry levy: An interrupted time series analysis of surveillance data

BACKGROUND

Sugar-sweetened beverages (SSBs) are the primary source of dietary added sugars in children, with high consumption commonly observed in more deprived areas where obesity prevalence is also highest. Associations between SSB consumption and obesity in children have been widely reported. In March 2016, a two-tier soft drinks industry levy (SDIL) on drinks manufacturers to encourage reformulation of SSBs in the United Kingdom was announced and then implemented in April 2018. We examined trajectories in the prevalence of obesity at ages 4 to 5 years and 10 to 11 years, 19 months after the implementation of SDIL, overall and by sex and deprivation.

METHODS AND FINDINGS

Data were from the National Child Measurement Programme and included annual repeat cross-sectional measurement of over 1 million children in reception (4 to 5 years old) and year 6 (10 to 11 years old) in state-maintained English primary schools. Interrupted time series (ITS) analysis of monthly obesity prevalence data from September 2013 to November 2019 was used to estimate absolute and relative changes in obesity prevalence compared to a counterfactual (adjusted for temporal variations in obesity prevalence) estimated from the trend prior to SDIL announcement. Differences between observed and counterfactual estimates were examined in November 2019 by age (reception or year 6) and additionally by sex and deprivation quintile. In year 6 girls, there was an overall absolute reduction in obesity prevalence (defined as >95th centile on the UK90 growth charts) of 1.6 percentage points (PPs) (95% confidence interval (CI): 1.1, 2.1), with greatest reductions in the two most deprived quintiles (e.g., there was an absolute reduction of 2.4 PP (95% CI: 1.6, 3.2) in prevalence of obesity in the most deprived quintile). In year 6 boys, there was no change in obesity prevalence, except in the least deprived quintile where there was a 1.6-PP (95% CI: 0.7, 2.5) absolute increase. In reception children, relative to the counterfactual, there were no overall changes in obesity prevalence in boys (0.5 PP (95% CI: 1.0, -0.1)) or girls (0.2 PP (95% CI: 0.8, -0.3)). This study is limited by use of index of multiple deprivation of the school attended to assess individual socioeconomic disadvantage. ITS analyses are vulnerable to unidentified cointerventions and time-varying confounding, neither of which we can rule out.

CONCLUSIONS

Our results suggest that the SDIL was associated with decreased prevalence of obesity in year 6 girls, with the greatest differences in those living in the most deprived areas. Additional strategies beyond SSB taxation will be needed to reduce obesity prevalence overall, and particularly in older boys and younger children.

Experiences of nurses and coordinators in a childhood obesity prevention trial based on motivational interviewing within Swedish child health services

Purpose

To explore the experiences of nurses and coordinators in the PRIMROSE childhood obesity prevention trial, and to understand the factors that might help to improve the outcome of future primary prevention of obesity.

Methods

Using a qualitative approach, data were obtained by interviewing nine intervention nurses and three regional study coordinators. All participants were female. The interviews were transcribed and analysed using content analysis.

Results

Two themes emerged: The nurses experienced that it was rewarding to participate in the trial, but challenging to combine the intervention with regular work; and The study coordinators experienced that they were in a difficult position handling the conflicting needs of the research group and the nurses’ commitment to usual child health care services. The importance of support, encouragement, briefer and simpler intervention, and adaptation of the training in motivational interviewing to the setting was emphasized. Stress and lack of time were major barriers to deliver the intervention as intended.

Conclusions

Although the PRIMROSE intervention was developed in collaboration with representatives from the child health services, and additional research funding was provided to compensate for time spent working with the trial, nurses experienced stress and time constraints. .

Building capacity for the use of systems science to support local government public health planning: a case study of the VicHealth Local Government Partnership in Victoria, Australia

OBJECTIVE

To present an approach to build capacity for the use of systems science to support local communities in municipal public health and well-being planning.

DESIGN

Case study.

SETTING

Local government authorities participating in the VicHealth Local Government Partnership in Victoria, Australia.

PARTICIPANTS

Local government staff members were trained in community-based system dynamics (CBSD), and group model building (GMB) techniques to mobilise local community efforts. The trained local government facilitation teams then delivered GMB workshops to community stakeholder groups from 13 local government areas (LGA)s.

MAIN OUTCOMES

Training in CBSD was conducted with council facilitation teams in 13 LGAs, followed by the local delivery of GMB workshops 1-3 to community stakeholders. Causal loop diagrams (CLD) representing localised drivers of mental well-being, healthy eating, active living or general health and well-being of children and young people were developed by community stakeholders. Locally tailored action ideas were generated such as well-being classes in school, faster active transport and access to free and low-cost sporting programmes RESULTS: Overall, 111 local government staff participated in CBSD training. Thirteen CLDs were developed, with the stakeholders that included children, young people and community members, who had participated in the GMB workshops across all 13 council sites. Workshop 3 had the highest total number of participants (n=301), followed by workshop 1 (n=287) and workshop 2 (n=171).

CONCLUSIONS

Local facilitation of the CBSD process has developed community informed and locally relevant CLDs that will be used to lead local action to improve the well-being of children and young people. Training employees in CBSD is one approach to increase systems thinking capacity within local government.

Childhood Obesity and Incorrect Body Posture: Impact on Physical Activity and the Therapeutic Role of Exercise

Obesity is associated with various dysfunctions of the organism, including musculoskeletal problems. In this narrative review, we aim to consider postural problems in children and adolescents with obesity, focusing on the relationship with its negative impact on physical activity, and to discuss the role of exercise as a therapeutic approach. The body reacts to excess weight by changing its normal balance, and the somatosensory system of children with obesity is forced to make major adjustments to compensate for postural problems. These adaptations become more difficult and tiring if activities that require continuous postural changes and multi-tasking are engaged in. Children with obesity have less body control and functional ability due to the excess fat mass, which reduces their ability to perform motor skills and take part in physical activity. Appropriate early interventions for the management of musculoskeletal problems are needed to ensure healthy growth and to prevent comorbidities in childhood and adulthood. Prevention programs must be based not only on the reduction of body weight but also on the definition of correct postural habits from an early age. It is equally important to provide correct information on the types and doses of physical activity that can help prevent these problems.

Barriers and enablers to the implementation of school-based obesity prevention strategies in Jeddah, KSA

Introduction

Despite schools' recognised role in mitigating childhood overweight, many schools fail to implement physical activity or nutrition strategies. The current study explored the enablers and barriers to implementing obesity prevention strategies in Jeddah, KSA.

Methods

This research is based on 14 semi-structured interviews with intermediate school principals and sports teachers to gain insight into their perception of barriers and enablers to implementing obesity prevention strategies. Themes were deductively generated from the data.

Results

Participants estimated the prevalence of overweight and obesity among their students to be between 3 and 15% with an increasing trend, particularly among female students. Participants identified five categories of barriers to implementation of obesity prevention intervention: curriculum; schools strategies promoting healthy weight; lack of resources; student’s lifstyle; and a lack of teachers in nutrition and sports. School regulations, staff and sufficient resources were the most frequently reported enablers. Participants also identified food services, awareness, and partnerships as barriers and enablers.

Conclusion

There is a need for better infrastructure and financial support for schools and professional development opportunities for teachers from the Saudi Ministry of Education. The Ministry also needs to support the development of multilevel health promotion strategies at school and home and reach out to the broader community.

The Influence of Adolescent Sport Participation on Body Mass Index Tracking and the Association between Body Mass Index and Self-Esteem over a Three-Year Period

This study aimed to (1) investigate gender-specific characteristics associated with low sport participation among UK adolescents, and (2) assess gender-specific BMI tracking, and gender-specific associations between BMI and self-esteem based on different levels of adolescent sport participation. Participants were 9046 (4523 female) UK adolescents. At 11- and 14 years self-esteem was self-reported and BMI was calculated from objectively measured height and weight. At 11- years sport participation was parent-reported. Gender-specific sport participation quartile cut-off values categorised boys and girls separately into four graded groups. Gender-specific χ² and independent samples t tests assessed differences in measured variables between the lowest (Q1) and highest (Q4) sport participation quartiles. Adjusted linear regression analyses examined BMI tracking and associations between BMI and self-esteem scores. Gender-specific analyses were conducted separately for sport participation quartiles. Compared to Q4 boys and girls, Q1 boys and girls were more likely to be non-White, low family income, have overweight/obesity at 11 years and report lower self-esteem at 11 years and 14 years. BMI at 11 years was positively associated with BMI at 14 years for boys and girls across sport participation quartiles. BMI at 11 years was inversely associated with self-esteem scores at 11 years for Q1 and Q2 boys, and Q1 and Q4 girls. BMI at 11 years was inversely associated with self-esteem scores at 14 years for Q1, Q3 and Q4 boys, and Q1, Q2, Q3 and Q4 girls. Gender and sport participation influence BMI tracking and the BMI and self-esteem association among adolescents.

Pediatric youth who have obesity have high rates of adult criminal behavior and low rates of homeownership

Objectives:

The social outcomes in adulthood for pediatric patients with obesity are not well-described. This study investigated lifetime criminal behavior and homeownership in youth with obesity.

Methods:

Retrospective data on all children enrolled in the weight management program from 1999 to 2009 and who completed exercise testing were collected. Demographic and public record collection included body habitus, death records, real estate transactions, and criminal conviction history with comparisons made to published normative data.

Results:

In the children with obesity studied (N = 716; 12.0 ± 3.1 years old), the now-adult patients (28.5 ± 3.7 years) had a 1.5% mortality rate (11/716). Overall, 9.6% of these adults were convicted of a felony compared to ~7% lifetime prevalence in Ohio (p = 0.03). Also, 14.7% of study patients purchased a home compared to 38.3% of Midwest adults <30 years old (p < 0.0001). Mortality, history of a criminal conviction, or homeownership was associated with any exercise or study parameter.

Conclusion:

Children with obesity appear to have greater social risk than their peers in adulthood with higher rates of criminal behavior and lower rates of homeownership. This appears to highlight the need for treatment in this vulnerable group of children and young adults.

Does a Healthy Lifestyle Lower the Elevated Risk of Obesity Caused by Caesarian Section Delivery in Children and Adolescents?

Background: Both caesarean section (CS) and lifestyle were linked with child adiposity. This study aimed to investigate whether CS delivery is linked with elevated risk of child adiposity regardless of a healthy lifestyle. Methods: All the subjects in this study came from a baseline survey of a national school-based program on healthy lifestyle interventions against adiposity among Chinese children and adolescents. A questionnaire was used to collect the information on delivery mode and lifestyle. According to the weighted lifestyle score, subjects were categorized into healthy, intermediate, and unhealthy lifestyle. Results: A total of 44,961 children aged 6−18 years were enrolled in the current study. Overall, 41.9% (18,855/44,961) of children were delivered by CS. Compared with children delivered by vaginal delivery, children delivered by CS had a higher adiposity risk (OR = 1.56; 95%CI: 1.46−1.66; p < 0.001) after adjustment for age, sex, region, mother adiposity, ethnicity, and weighted lifestyle factors. Compared with children with a healthy lifestyle, children with an unhealthy lifestyle had a higher risk of child adiposity (OR = 1.31; 95%CI: 1.19−1.44). Children delivered by CS who had an unhealthy lifestyle had a 106% higher (OR = 2.06; 95%CI: 1.79−2.37) risk of child adiposity compared with children delivered by vaginal delivery who had a healthy lifestyle. However, keeping a healthy lifestyle in later life seems not to offset the increased risk of child adiposity caused by CS (OR = 1.59; 95%CI: 1.39−1.82). Conclusions: Both CS and unhealthy lifestyle were linked with child adiposity risk. Keeping a healthy lifestyle did not counteract the elevated risk of child adiposity caused by CS.

The Association between Obesity and Depression among Children and the Role of Family: A Systematic Review

One of the most critical factors that affects or leads to obesity is depression. However, another point of view is that obesity leads to depression. This systematic review estimates evidence arising from observational and systematic studies concerning the association between obesity and depression in children and adolescents. Moreover, the role of the family environment is investigated in this review. A systematic literature search was performed for research conducted between 2014 and 2021 on PubMed. The basic inclusion criteria were the language, study issue and type, and age of the participants. Studies that examined non-healthy populations, or were not related, or with no access were excluded. Titles and abstracts were screened independently, and full-text manuscripts meeting inclusion criteria were extracted. Finally, twenty-seven studies were retained. Most of them highlighted a positive association between obesity and depression. However, it is not clear whether obesity leads to depression or vice versa. Our review also revealed that the role of the family in this association has not been well studied and understood, since only one study addressed the issue. The evidence from our review emphasizes major public health issues; therefore, appropriate health policies should be developed. Moreover, additional research is required to fully understand the role of the family environment in the association between depression and obesity in childhood.

Assessing Body Esteem in Adolescents: psychometric properties of the Spanish version of the Body Esteem Scale (BESAA-S)

Background

“How do I perceive my own body?“ is a central question during adolescence, which addresses the subjective assessment of body image, called Body Esteem. Although concern about body esteem increases during adolescence, there is a lack of psychometrically validated measures to assess it specifically among Spanish adolescents.

Objective

This study aims to validate the Body-Esteem Scale for Adolescents and Adult populations (BESAA), a widely used measure of body esteem across cultures, among the Spanish adolescent population.

Methods

The cross-cultural adequacy and acceptability of the Argentinian-Spanish version by Forbes et al., (2012) were pilot tested and the questionnaire was completed by 1,258 students (Mage = 15.56). Next, several psychometric analyses were carried out: exploratory (AFE) and confirmatory (CFA) factorial structure, convergent and discriminant validity, nomological validity, internal consistency, and temporal reliability.

Results

The AFE and CFA supported a reduced Spanish version of the BESAA of 14 items (BESAA-S) and maintained the original three-factor structure (BE-Weight, BE-Appearance, and BE-Attribution subscales). The BESAA-S showed acceptable internal consistency and strong test-retest reliability. Discriminant validity between subscales was appropriate, and convergent validity was appropriate except for the BE-Attribution subscale. Nomological validity was supported through significant correlations with body appreciation, general self-esteem, sociocultural attitudes towards appearance, and disordered eating symptoms. Body esteem was negatively associated with weight status.

Conclusions

This study presents a culturally appropriate, shortened Spanish BESAA as a reliable instrument for body esteem assessment among Spanish speaking adolescents.

Parents' experiences following conversations about their young child's weight in the primary health care setting: a study within the STOP project

BACKGROUND

In primary healthcare, conversations between clinicians and parents about young children's overweight are key to providing support and initiating weight management. However, given the sensitivity of this topic, these conversations are difficult for both clinicians and parents and are sometimes delayed or avoided. To understand the emotional impact of these conversations, this study aims to shed light on parents' experiences following conversations with primary care nurses about their child's overweight.

METHODS

Participants were recruited through a childhood obesity randomized controlled trial (RCT) conducted in Sweden. Telephone-based semi-structured interviews were conducted with 17 parents (mean age 40; the majority were women (n = 12/17), had a university degree (n = 14/17) and were born in Sweden (n = 13/16)). Their children were between 3 and 7 years old (mean age 4.8 years) with overweight (n = 7) or obesity (n = 10). The interviews were recorded, transcribed, and analyzed using thematic analysis.

RESULTS

Two main themes were developed. Theme 1, 'Receiving the overweight/obesity diagnosis', explores parents' reactions to the conversation with the primary care nurse. Depending on how the nurse presented the topic, conversations either fostered an alliance between the parent and the nurse, encouraging parents to reflect and develop insights about the child's and the family's needs (subtheme Conversations that empower), or felt limited, uncomfortable, or belittling (subtheme Conversations that provoke resistance). Theme 2, 'Parenting a child with a formal diagnosis of obesity', explores challenges parents faced following the weight conversations, including managing their own feelings and concerns (subtheme Fear of transferring weight anxiety), dealing with others' reactions (subtheme Involve family and manage surroundings) and asking for and receiving support from health care professionals (subtheme Obtain support from health care professionals).

CONCLUSIONS

While conversations with primary care nurses about children's weight were often emotional, most parents felt these conversations were ultimately helpful, as they encouraged them to enact positive lifestyle changes. Importantly, when nurses initiated conversations in a responsive, non-blaming way, inviting parents to reflect on their situation, parents felt more supported and empowered. These findings convey the importance of providing communication skills training to pediatric healthcare professionals, with particular focus on childhood overweight and obesity.

Perceptions of a family-based lifestyle intervention for children with overweight and obesity: a qualitative study on sustainability, self-regulation, and program optimization

BACKGROUND

Family-based lifestyle interventions (FBLIs) are an important method for treating childhood weight problems. Despite being recognized as an effective intervention method, the optimal structure of these interventions for children's overweight and obesity has yet to be determined. Our aim was to better understand participants' (a) implementation of behaviour strategies and long-term outcomes, (b) perceptions regarding the optimal structure of FBLIs, and (c) insights into psychological concepts that may explain the success of these programs.

METHODS

Purposive sampling was used to recruit participants. We conducted focus groups as well as one-to-one interviews with parents (n = 53) and children (n = 50; aged 7-13, M = 9.4 yr, SD = 3.1) three months following their involvement in a 10-week, multi-component, FBLI involving education and activities relating to healthy nutrition, physical activity, and behavior modification. Using an interpretivist approach, a qualitative study design was employed to examine participant experiences.

RESULTS

We identified three higher-order categories: (a) participants' program experiences and perceptions (b) lifestyle changes post-program, and (c) recommendations for optimizing family-based programs. Themes identified within these categories included (a) support and structure & content, (b) diet and physical activity, and (c) in-program recommendations and post-program recommendations.

CONCLUSIONS

We identified several challenges that can impair lasting behavior change (e.g., physical activity participation) following involvement in a FBLI. On optimizing these programs, participants emphasized fun, interactive content, interpersonal support, appropriate educational content, and behavior change techniques. Concepts rooted in motivational theory could help address calls for greater theoretical and mechanistic insight in FBLIs. Findings may support research advancement and assist health professionals to more consistently realize the potential of these interventions.

Changes and differences in school food standards (2010-2021) and free school meal provision during COVID-19 across the UK: Potential implications for children's diets

This paper explores changes to school food standards from 2010, free school meal provision during the COVID-19 pandemic across the UK and potential implications for children's diets. To obtain information on UK school food policies and free school meal provision methods we reviewed several sources including news articles, policy documents and journal articles. School food is an important part of the UK's health agenda and commitment to improving children's diets. Each UK nation has food-based standards implemented, however, only Scotland and Wales also have nutrient-based standards. School food standards in each nation have been updated in the last decade. Universal free school meals are available for children in the first 3 years of primary school in England and the first 5 years of primary school in Scotland, with plans announced for implementation of free school meals for all primary schoolchildren in Scotland and Wales. There is a lack of consistent monitoring of school food across the UK nations, and a lack of reporting compliance to the standards. Each nation differed in its response and management of free school meals during COVID-related school closures. Further, there are issues surrounding the monitoring of the methods to provide free school meal support during school closures. The role of school food has been highlighted during COVID-19, and with this, there have been calls for a review of free school meal eligibility criteria. The need for improved and consistent monitoring of school food across the UK remains, as does the need to evaluate the impact of school food on children's diets.

Physical Activity and Screen Time Practices of Family Child Care Providers: Do They Meet Best Practice Guidelines?

Background: Child care settings significantly influence children's physical activity (PA) and screen time (ST) behaviors, yet less research has been conducted in family child care homes (FCCHs) than in child care centers. While a few studies have measured family child care providers' (FCCPs') PA practices, none have used observation to assess which specific evidence-based, best practice guidelines FCCPs met or did not meet, and no previous studies have included Latinx providers. This article examines FCCPs' adherence to PA and ST best practice guidelines using primarily observational methods with diverse FCCPs (including Latinx). Methods: We examined baseline data from a cluster randomized trial including surveys and observational data collected at the FCCH to assess whether providers met specific PA and ST best practices from the Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) and the American Academy of Pediatrics. Results: Providers completed a telephone survey and participated in two full-day observations (n = 127; 72% Hispanic). Overall, only 4 of 14 PA and ST best practices were met by >50% of providers including: leading a planned PA class more than once a week; no ST during meal or snack; not modeling sedentary behavior; and providing families with information about children's ST. Best practices least likely to be met (<20% of providers) include: providing children with >60 minutes of outdoor play daily; providing children with >45 minutes of adult-led PA each day; participating in outdoor PA with children; participating in indoor PA with children; prompting and praising children for being active; and talking with children informally about the importance of PA. Conclusions: While FCCPs engage in some positive PA and ST practices, many providers do not meet best practice guidelines. There is a need for more research about how to overcome providers' personal and environmental barriers for meeting these guidelines as well as interventions and supports to overcome these barriers.

Possible Relationship Between the Oral and Gut Microbiome, Caries Development, and Obesity in Children During the COVID-19 Pandemic

The COVID-19 pandemic has brought health damage and socioeconomic disruptions, together with lifestyle disorders around the world. Children are one of the most commonly affected, mainly due to social isolation and changes in eating habits and physical activities. This way, the risk of weight gain and obesity is possibly enhanced, as well as poor oral hygiene conditions and early childhood caries (ECC) development during the lockdown. In children under 6 years of age, ECC is defined as carious lesions in one or more primary teeth, with or without cavitation. Importantly, alterations in the oral microbiome caused by changes in children lifestyles have much more than a local impact on oral tissues, interplaying with the gut microbiome and influencing systemic environments. Recent studies have been exploring the oral health conditions, eating habits, and weight gain in the childhood population during the COVID-19 pandemic; however, there is a lack of information concerning the association among oral and gut microbiome, dental caries, and obesity in the COVID-19 era. In this context, this review aimed at analyzing a possible relationship between the oral and gut microbiome, caries, and obesity in children during the COVID-19 pandemic.

Long-acting amylin analogues for the management of obesity

PURPOSE OF REVIEW

To summarize recent developments of long-acting amylin analogues for the treatment of obesity and to outline their mode of action.

RECENT FINDINGS

Amylin is a pancreatic hormone acting to control energy homeostasis and body weight. Activity at the calcitonin and amylin receptors in the area postrema seems to - at least partly - be responsible for these effects of amylin. Both preclinical and early-stage clinical studies investigating long-acting amylin receptor analogues demonstrate beneficial effects on body weight in obesity. Cagrilintide, a novel amylin analogue suitable for once-weekly administration, is in phase II clinical development and has shown promising body weight reducing effects alone and in combination with the glucagon-like peptide 1 receptor agonist semaglutide.

SUMMARY

Long-acting amylin analogues have emerged as a possible pharmacotherapy against obesity, but more studies are needed to support the utility and long-term effects of this strategy in relevant populations.

Simply too much: the extent to which weight bias internalization results in a higher risk of eating disorders and psychosocial problems

PURPOSE

Weight bias internalization (WBI) is associated with negative health consequences such as eating disorders and psychosocial problems in children. To date, it is unknown to what extent WBI considerably raises the risk of negative outcomes.

METHODS

Analyses are based on cross-sectional data of 1,061 children (9-13 years, M = 11, SD = 0.9; 52.1% female) who filled in the WBI scale (WBIS-C). First, ROC analyses were run to identify critical cut-off values of WBI (WBIS-C score) that identify those who are at higher risk for psychosocial problems or eating disorder symptoms (as reported by parents). Second, it was examined whether WBI is more sensitive than the relative weight status in that respect. Third, to confirm that the cut-off value is also accompanied by higher psychological strain, high- and low-risk groups were compared in terms of their self-reported depressive symptoms, anxious symptoms, body dissatisfaction, and self-esteem.

RESULTS

WBIS-C scores ≥ 1.55 were associated with a higher risk of disturbed eating behavior; for psychosocial problems, no cut-off score reached adequate sensitivity and specificity. Compared to relative weight status, WBI was better suited to detect disturbed eating behavior. Children with a WBIS-C score ≥ 1.55 also reported higher scores for both depressive and anxious symptoms, higher body dissatisfaction, and lower self-esteem.

CONCLUSION

The WBIS-C is suitable for identifying risk groups, and even low levels of WBI are accompanied by adverse mental health. Therefore, WBI is, beyond weight status, an important risk factor that should be considered in prevention and intervention.

Parents’ perceptions of their child’s weight among children in their first year of primary school: a mixed-methods analysis of an Australian cross-sectional (complete enumeration) study

Background/Objectives

To describe trends in overweight/obesity in early childhood for all children and those whose parents are concerned about their weight. To describe parents’ perceptions of their child’s weight and differences by their child’s anthropometric and sociodemographic factors.

Subjects/Methods

Analysis of the Kindergarten Health Check, a survey of all children enrolled in their first year of primary education in the Australian Capital Territory. Analysis of detailed data for 2014–2017, including qualitative analysis of parents’ comments on weight, and trends for 2001–2017.

Results

71,963 children participated in the survey between 2001 and 2017 (20,427 between 2014 and 2017). The average age of children (2001–2017) was 5 years and 9.6 months at the time of their physical health check. 2377 children (3.5%) were classified as obese based on measured body mass index (BMI) between 2001 and 2017, and a further 7766 (11.6%) overweight. Similar proportions were seen for 2014–2017. Among children with overweight/obesity in 2014–2017, 86.4% of parents (2479/2868) described their children’s weight as healthy and 13.3% (382/2868) as overweight/obese. Just 11.5% (339/2946) of parents whose children were later measured with overweight/obesity identified having a concern about their child’s weight.

Parental comments varied widely and were often incongruent with the known health risks associated with their child’s measured BMI. Comments from parents whose children were measured as obese often were normalising e.g., “born big, always big. Definitely NOT overweight, just bigger all over”, whilst parents of children in the healthy range expressed concerns about underweight.

Conclusion

Parents do not accurately perceive their child’s weight and few document concerns, even among children measuring in the obese BMI category. This lack of concern makes early interventions challenging as parents are in the “pre-contemplative” stage of behaviour change and may see public health campaigns or clinicians’ attempts to address their child’s weight as irrelevant or unhelpful.

Sugar-sweetened beverage consumption and overweight and obesity in adolescents in Ho Chi Minh City, Vietnam: a population-based analysis

BACKGROUND

The aim of this research was to describe the patterns of consumption of multiple sugar-sweetened beverages (including modern and traditional ones) among adolescents in Ho Chi Minh City and to identify a possible relationship between this consumption and overweight, obesity, and other factors.

METHODS

A secondary analysis from a cross-sectional study of 11-15-year-old students from 31 junior high schools across Ho Chi Minh City was used. We measured the students' anthropometric status and assessed beverage consumption using a validated Food Frequency Questionnaire. Multivariate logistic regression models were used to identify the association between the consumption of sugar-sweetened beverages, obesity and other factors.

RESULTS

The sugar-sweetened beverages (SSB) ranged widely from modern soft drinks and powdered drinks to traditional sugar-added fruit and leaf juices, and milk-based drinks. These beverages were very popular among 2,660 participants with 36% consuming at least one variety daily. Factors positively associated with sugar-sweetened beverage consumption included a higher level of physical activity, higher consumption of fast foods, and daily fruit and vegetable consumption. We found a negative association between milk-based SSBs and the overweight and obesity status of the students, i.e. every kcal more of fresh milk with sugar and condensed milk can reduce an obesity odd of 0.005 (95% CI [0.002-0.008], p < 0.001) and 0.004 (95% CI [0.002-0.010], p = 0.044) consecutively. None of the other SSBs was significantly related to adolescent overweight and obesity.

CONCLUSIONS

Milk-based drinks potentially protect adolescents against overweight and obesity. Further research to assess this protection is needed.
