DEVELOPMENT, FEASIBILITY, AND ACCEPTABILITY OF A BEHAVIORAL WEIGHT AND SYMPTOM MANAGEMENT INTERVENTION FOR BREAST CANCER SURVIVORS AND INTIMATE PARTNERS.

BackgroundWeight gain is common for breast cancer survivors and associated with disease progression, recurrence, and mortality. Traditional behavioral programs fail to address symptoms (i.e., pain, fatigue, distress) experienced by breast cancer survivors that may interfere with weight loss and fail to capitalize on the concordance in weight-related health behaviors of couples. This study aimed to develop and examine the feasibility and acceptability of a behavioral weight and symptom management intervention for breast cancer survivors and their intimate partners.Materials and MethodsInterviews were conducted with N=14 couples with overweight/obesity to develop the intervention. Intervention feasibility and acceptability were examined through a single-arm pilot trial (N=12 couples). Patterns of change in intervention targets were examined for survivors and partners.ResultsThemes derived from interviews were used to develop the 12-session couple-based intervention, which included components from traditional behavioral weight management interventions, appetite awareness training, and cognitive and behavioral symptom management protocols. Couples also worked together to set goals, create plans for health behavior change, and adjust systemic and relationship barriers to weight loss. Examples were tailored to the experiences and symptom management needs of breast cancer survivors and partners. The intervention demonstrated feasibility (attrition: 8%; session completion: 88%) and acceptability (satisfaction). Survivors and partners experienced reductions in weight and improvements in physical activity, eating behaviors, emotional distress, and self-efficacy. Survivors evidenced improvements in fatigue and pain.ConclusionsA behavioral weight and symptom management intervention for breast cancer survivors and partners is feasible, acceptable, and is potentially efficacious.

Changes in Weight-Related Health Behaviors and Social Determinants of Health among Youth with Overweight/Obesity during the COVID-19 Pandemic.

Objectives: To assess changes in weight-related health behaviors and social determinants of health (SDoH) among youth with overweight/obesity during the coronavirus disease 2019 (COVID-19) pandemic. Methods: We assessed weight-related health behaviors (physical activity, screen time, sleep, and diet) and SDoH (food insecurity, income/childcare, and caregivers' perceived stress) before vs. during the pandemic with a survey administered August-October 2020 to caregivers of 2-17-year olds and adolescents 13-17 years old with BMI ≥85th percentile seen in clinic within 6 months prepandemic. We analyzed changes in continuous variables using paired t-tests and categorical variables with McNemar's or Fisher's exact tests, and the influence of social determinants on behavior change using multivariable regression models. Results: A total of 129 caregivers and 34 adolescents completed surveys. Compared with prepandemic, caregivers reported youth decreased moderate/vigorous physical activity (-87.4 [205.7] minutes/week, p < 0.001) and increased recreational screen time (2.5 [2.1] hours/day, p < 0.001). Fewer had regular bedtimes (before: 89% and during: 44%, p < 0.001) and more ate most meals with television (before: 16% and during: 36%, p < 0.001). Food insecurity increased from 27% to 43% (p < 0.001), 45% reported reduced household income, and caregivers with moderate/high perceived stress scale scores increased from 43% to 64% (p < 0.001). Moderate/high caregiver stress and food insecurity were associated with greater magnitudes of adverse behavior change. Conclusion: Alarming changes in health behaviors among youth with overweight/obesity, particularly among those with stressed caregivers and food insecurity, may increase prevalence of obesity-related comorbidities and exacerbate health disparities. There is an urgent need to expand access to effective interventions for overweight/obesity that address psychosocial stressors.

Health Behaviors in the LGB+ Population: Variation Across Adulthood

Health behaviors, which predict physical and mental health, are patterned by social factors, with some groups engaging in more health-enhancing behaviors than others. LGB+ people face more economic and social barriers to participation in healthy behaviors, along with the stress of discrimination that could lead to unhealthy behaviors to cope. Although some studies have examined variation in health behaviors by sexual identity, they focus almost exclusively on adolescents and young adults. However, such differences may decline across adulthood, as stress related to sexual identity declines with age among LGB+ individuals. Addressing this issue, we use data from the National Health Interview Survey (2016-2018) to examine differences by sexual identity in substance use, weight-related behaviors, healthcare utilization, and sleep. We compare the patterns across three age groups – young, middle-aged, and older adults. Results for each health behavior reveal that differences by sexual identity are indeed greatest among young adults. The magnitude is smaller in middle age, and no significant differences by sexual minority status are observed at older ages.

Characterizing behavior change techniques used in the self-management of binge eating and weight: Applying a user-centered design approach

User-centered design methods aim to increase intervention engagement by focusing on consumers' needs and preferences. We conducted a needs assessment (the first step in user-centered design) via a digital diary study to understand how individuals with recurrent binge eating (≥12 episodes in 3 months) and obesity (BMI ≥30 kg/m2) manage these problems in their day-to-day lives and the approaches they use to change their behavior. Specifically, we applied the Behavior Change Technique (BCT)-Taxonomy to characterize which standardized BCTs individuals use to change binge eating and health-related behaviors and their motivations to use them, to inform the design of a mobile intervention. We analyzed qualitative data from 22 adults (64% female, 32% White) who submitted 176 diary entries. For each entry, we coded the BCTs used, motivation for use, and whether the BCT(s) were perceived as beneficial for behavior change. Across participants, investigators identified 50 of the 93 standardized BCTs (54%). Each participant used an average of 12 (SD = 4) BCTs, most commonly Behavior Substitution (72.3%), Distraction (68.2%), Goal Setting (Behavior) (63.6%), Action Planning (59.1%) and Adding Objects to the Environment (59.1%). More BCTs were coded as beneficial (49%) versus detrimental (24%) or neutral (27%). Techniques were most commonly motivated by preventing binge eating (95.5%), losing weight (95.5%), reducing unhealthy food choices (90.9%), or managing stress (59.1%). Results help inform how interventions could be designed to support consumers in changing binge eating and weight-related behaviors, although such designs would need to be tested for their impact on engagement and outcomes.

Ecological Momentary Assessment of Weight-Related Behaviors in the Home Environment of Children From Low-Income and Racially and Ethnically Diverse Households: Development and Usability Study.

BackgroundEcological momentary assessment (EMA) is an innovative tool for capturing in-the-moment health behaviors as people go about their daily lives. EMA is an ideal tool to measure weight-related behaviors, such as parental feeding practices, stress, and dietary intake, as these occur on a daily basis and vary across time and context. A recent systematic review recommended standardized reporting of EMA design for studies that address weight-related behaviors.ObjectiveTo answer the call for reporting study designs using EMA, this paper describes in detail the EMA design of the Family Matters study and how it was adapted over time to improve functionality and meet the needs of a racially, ethnically, and socioeconomically diverse sample.MethodsFamily Matters is an incremental, 2-phased, mixed methods study, conducted with a racially and ethnically diverse, immigrant and refugee sample from largely low-income households, designed to examine risk and protective factors for child weight and weight-related behaviors in the home environment. The Family Matters study intentionally recruited White, Black, Hmong, Latino, Native American, and Somali parents with young children. Parents in phase 1 of the study completed 8 days of EMA on their smartphones, which included signal-contingent surveys (eg, asking about the parent’s stress at the time of the survey), event-contingent surveys (eg, descriptions of the meal the child ate), and end-of-day surveys (eg, overall assessment of the child’s day).ResultsA detailed description of EMA strategies, protocols, and methods used in phase 1 of the Family Matters study is provided. Compliance with EMA surveys and participants’ time spent completing EMA surveys are presented and stratified by race and ethnicity. In addition, lessons learned while conducting phase 1 EMA are shared to document how EMA methods were improved and expanded upon for phase 2 of the Family Matters study.ConclusionsThe results from this study provided an important next step in identifying best practices for EMA use in assessing weight-related behaviors in the home environment.International Registered Report Identifier (IRRID)DERR1-10.2196/30525

HomeStyles-2: Randomized controlled trial protocol for a web-based obesity prevention program for families with children in middle childhood

BackgroundParents are children's primary role models, are food and physical activity gatekeepers, and create the home structure/lifestyle environment. Thus, parents strongly influence children's weight-related behaviors and have the opportunity to cultivate a “culture of health” within the home. Yet, there is a dearth of evidence-based obesity prevention intervention programs, especially for families with children aged 6–11 years, commonly called middle childhood. MethodsThe aim of the HomeStyles-2 online learning mode RCT is to determine whether this novel, age-appropriate, family intervention enables and motivates parents to shape home environments and weight-related lifestyle practices (i.e.,diet, exercise, sleep) to be more supportive of optimal health and reduced obesity risk in middle childhood youth more than those in the control condition. The RCT will include the experimental group and an attention control group. The participants will be parents with school-age children who are systematically randomly assigned by computer to study condition. The HomeStyles intervention is predicated on the social cognitive theory and a social ecological framework. The RCT will collect sociodemographic characteristics of the participant, child, and partner/spouse; child and parent health status; parent weight-related cognitions; weight-related behaviors of the parent and child; and weight-related characteristics of the home environment. Deliverables Enrollment for this study will begin in 2022. DiscussionThis paper describes these aspects of the HomeStyles-2 intervention: rationale; sample eligibility criteria and recruitment; study design; experimental group intervention theoretical and philosophical underpinnings, structure, content, and development process; attention control intervention; survey instrument development and components; outcome measures; and planned analyses.

The impact of a community-based intervention on weight, weight-related behaviours and health-related quality of life in primary school children in Victoria, Australia, according to socio-economic position

BackgroundApproximately a quarter of Australian children are classified as overweight or obese. In high-income countries, childhood obesity follows a socio-economic gradient, with greater prevalence amongst the most socio-economically disadvantaged children. Community-based interventions (CBI), particularly those using a systems approach, have been shown to be effective on weight and weight-related behaviours. They are also thought to have an equitable impacts, however there is limited evidence of their effectiveness in achieving this goal.MethodsSecondary analysis was conducted on data collected from primary school children (aged 6–13 years) residing in ten communities (five intervention, five control) involved in the Whole of Systems Trial of Prevention Strategies for Childhood Obesity (WHO STOPS) cluster randomised trial in Victoria, Australia. Outcomes included Body Mass Index z-score (BMI-z) derived from measured height and weight, self-reported physical activity and dietary behaviours and health related quality of life (HRQoL). Repeat cross-sectional data from 2015 (n = 1790) and 2019 (n = 2137) were analysed, stratified by high or low socio-economic position (SEP). Multilevel linear models and generalised estimating equations were fitted to assess whether SEP modified the intervention effect on the outcomes.ResultsThere were no overall changes in BMI-z for either SEP strata. For behavioural outcomes, the intervention resulted in a 22.5% (95% CI 5.1, 39.9) point greater improvement in high-SEP compared to low-SEP intervention schools for meeting physical activity guidelines. There were also positive dietary intervention effects for high SEP students, reducing takeaway and packaged snack consumption, although there was no significant difference in effect between high and low SEP students. There were positive intervention effects for HRQoL, whereby scores declined in control communities with no change in intervention communities, and this did not differ by SEP.ConclusionThe WHO STOPS intervention had differential effects on several weight-related behaviours according to SEP, including physical activity. Similar impacts on HRQoL outcomes were found between high and low SEP groups. Importantly, the trial evaluation was not powered to detect subgroup differences. Future evaluations of CBIs should be designed with an equity lens, to understand if and how these types of interventions can benefit all community members, regardless of their social and economic resources.

The Impact of Structured versus Less-Structured Days on Weight-Related Behaviors in Rural Children

Research utilizing the ‘Structured Days Hypothesis’ suggests that children’s weight-related behaviors are more favorable on days with more structure, routine, and consistency. The purpose of this study was to investigate weight-related behaviors of rural children on ‘structured’ versus ‘less-structured’ days. A 14-day repeated measures observational study was conducted of 52 parent-child dyads (child mean age 9.2 ± SD 1.9 years; 60% female). Participating parents/guardians reported evening screen-time and sleep (duration and timing). Mixed effect models compared behaviors between structured (e.g., school or camp day) and less-structured days (no formal program). Parent reported sleep duration of their child was −63 minutes/night less (95%CI: −74.6, −50.7 min/night), bed/wake times were earlier, and all children engaged in less screen time after 8:00PM on structured days compared to less-structured days (−34.5 min, 95%CI: −42.0, −27.1). Initial evidence suggests that on structured days children engage in favorable weight-related behaviors compared to less-structured days. Additional research with larger and more diverse samples of rural children is warranted; however, given preliminary findings social work practitioners in rural communities should increase social service-related program and planning that promote interventions focused on positive changes in children’s weight related behaviors.

The Relationship of Perceived Body Image, Body Mass Index and Physical Activity with Weight Status among Students at King Abdulaziz University Hospital

Aim: Identify the relation between poor esteem for body image and weight-related behaviors. The results will help increase awareness and improve students’ lifestyles to have a better body image and achieve ideal body weight.&#x0D; Methods: A cross-sectional study was conducted among King Abdulaziz University medical students (n= 460) between July to the end of August 2019. Data was collected using the International physical activity questionnaire (IPAQ), figure rating scale (FRS) and analyzed using SPSS software.&#x0D; Result: The results showed that the average Body Mass Index (BMI) was 24.80 ± 11.89. Participant sex was an important factor influencing the prevalence of obesity; male students were more obese than female students with a significant difference (p&lt;0.001). The level of body satisfaction was also affected by gender. Students in preclinical years were more likely to gain weight more than clinical years students.&#x0D; Conclusion: The results show a significant relationship between body satisfaction and gender (P&lt;0.0001) despite having diverse BMIs. Overweight and obese males and females' participants had the lowest body satisfaction. Females who were too thin and had low BMIs described themselves as normal, while males describe themselves as too thin. Conversely, females with high BMIs described themselves as too fat, while males described themselves as normal. This could be due to different factors. Also, underweight females and males have high body satisfaction, which can lead to dangerous behaviors to maintain low body weight which cause negative health consequences.

Emerging Adults and Social Distancing During COVID-19: Who Was More Likely to Follow Guidelines and What Were the Correlates With Well-Being and Weight-Related Behaviors?

The aim of this study is to identify the prevalence, predictors, and psychosocial well-being (depressive symptoms, stress) and weight-related behavior (eating behaviors, physical activity, and sedentary behavior) correlates of social distancing during COVID-19 among emerging adults. A rapid-response survey was sent to participants ( n=720; mean age=24.7 ± 2.0 years, 62% female) in a population-based cohort study in Minnesota during April–October 2020. Half of emerging adults reported fully social distancing. Emerging adults from White backgrounds were least likely to social distance while those from Asian backgrounds were most likely to social distance, in addition to those living with a parent. Females who partially/did not social distance reported less healthy eating behaviors, while males and “essential workers” reported higher levels of psychosocial distress. Public health messaging and practical supports for social distancing may need to be made more relevant to emerging adults during public health crises. Resources may need to differ depending on sex of emerging adult.

Parenting Stress, Child Weight-Related Behaviors, and Child Weight Status.

Background: There has been limited examination of the association between parenting stress and child weight-related behaviors. We aimed to determine whether parenting stress is associated with child weight-related behaviors, including physical activity, screen time, diet, sedentary time, and eating in the absence of hunger (EAH). Secondarily, we assessed association between parenting stress and child weight status. Methods: Mother-child dyads (N = 291) enrolled in the Newborn Epigenetic STudy (NEST), a longitudinal cohort study, completed surveys to describe parenting stress, and child diet. Children participated in the EAH task and wore accelerometers to assess sedentary time and physical activity. Child weight status was assessed using measured height and weight. Outcomes and exposures were examined using generalized linear models and restricted cubic splines as appropriate based on linear lack-of-fit test. Results: Child sedentary time and vegetable consumption were inversely associated with parenting stress (Total Stress B = -0.78; 95% confidence interval [CI]: -1.35 to -0.20; p = 0.017; and Total Stress adjusted odds ratio [aOR] = 0.98; 95% CI: 0.99 to 1.00; p = 0.022, respectively). Child screen time was directly associated with parenting stress (Total Stress = aOR 1.01; 95% CI: 1.00-1.02; p = 0.032). Fast-food intake was nonlinearly associated with parenting stress. There was no evidence of association between parenting stress and child EAH, physical activity, or weight status. Associations between parenting stress and child weight-related behaviors were not moderated by race or family structure. Conclusions: Parenting stress was associated with important child weight-related behaviors but not weight status. Management of parenting stress may represent a reasonable adjunct to family-based behavioral interventions.

Relation of social network support to child health behaviors among children in treatment for overweight/obesity.

Little is known about the influence of social network support on child health behaviors in the context of weight-loss interventions. This study examined the associations between a child's co-participation (i.e., network support) in weight-related health behaviors (i.e., physical and sedentary activity, eating behavior) and the child's own health behaviors during family-based behavioral treatment (FBT). Children (n = 241) with overweight/obesity (mean age = 9.4 ± 1.3y; 63% female) completed semi-structured interviews assessing network support for healthy/unhealthy eating and physical/sedentary activity, and a 3-day dietary recall. Physical activity was assessed with accelerometry, and sedentary activity was measured via parent-reported child screen time use. All assessments were taken at baseline and after 4months of FBT. Hierarchical linear regressions examined changes in network support as they related to changes in health behaviors from baseline to the end of FBT. Changes in network support for healthy eating were related to changes in vegetable, but not fruit, intake across FBT, while changes in network support for unhealthy eating were negatively related to changes in diet quality. Changes in network support for sedentary activity were negatively related to changes in minutes of physical activity and positively related to changes in screen time. The present findings suggest that a child's network support for health behaviors may relate to behavior change among children during FBT and provide opportunities for targeted intervention.

Effect of school-based body mass index reporting in California public schools: a randomized clinical trial

Importance Annually, US schools screen millions of students’ body mass index (BMI) and report the results to parents, with little experimental evidence on potential benefits and harms. Objective To determine the impact of school-based BMI reporting on weight status and adverse outcomes (weight stigmatization and weight-related perceptions and behaviors) among a diverse student population. Design, Setting, and Participants Cluster randomized clinical trial. The Fit Study (2014-2017) randomized 79 California schools to BMI screening and reporting (group 1), BMI screening only (group 2), or control (no BMI screening or reporting [group 3]) in grades 3 to 8. The setting was California elementary and middle schools. Students in grades 3 to 7 at baseline participated for up to 3 years. A modified intent-to-treat protocol was used. Data analysis was conducted from April 13, 2017, to March 26, 2020. Interventions School staff assessed BMI each spring among students in groups 1 and 2. Parents of students in group 1 were sent a BMI report each fall for up to 2 years. Main Outcomes and Measures Changes in BMIzscore and in adverse outcomes (based on surveys conducted each fall among students in grades 4 to 8) from baseline to 1 and 2 years of follow-up. Results A total of 28 641 students (14 645 [51.1%] male) in grades 3 to 7 at baseline participated in the study for up to 3 years. Among 6534 of 16 622 students with a baseline BMI in the 85th percentile or higher (39.3%), BMI reporting had no effect on BMIzscore change (−0.003; 95% CI, −0.02 to 0.01 at 1 year and 0.01; 95% CI, −0.02 to 0.03 at 2 years). Weight dissatisfaction increased more among students having BMI screened at school (8694 students in groups 1 and 2) than among control participants (5674 students in group 3). Results of the effect of BMI reporting on other adverse outcomes were mixed: compared with the control (group 3), among students weighed at school (groups 1 and 2), weight satisfaction declined more after 2 years (−0.11; 95% CI, −0.18 to −0.05), and peer weight talk increased more after 1 year (0.05; 95% CI, 0.01-0.09); however, concerning weight control behaviors declined more after 1 year (−0.06; 95% CI, −0.10 to −0.02). Conclusions and Relevance Body mass index reports alone do not improve children’s weight status and may decrease weight satisfaction. To improve student health, schools should consider investing resources in evidence-based interventions. Trial Registration ClinicalTrials.gov Identifier:NCT02088086

Translation of the Weight-Related Behaviours Questionnaire into a Short-Form Psychosocial Assessment Tool for the Detection of Women at Risk of Excessive Gestational Weight Gain.

The identification and measurement of psychosocial factors that are specific to pregnancy and relevant to gestational weight gain is a challenging task. Given the general lack of availability of pregnancy-specific psychosocial assessment instruments, the aim of this study was to develop a short-form psychosocial assessment tool for the detection of women at risk of excessive gestational weight gain with research and clinical practice applications. A staged scale reduction analysis of the weight-related behaviours questionnaire was conducted amongst a sample of 159 Australian pregnant women participating in the Women and Their Children’s Health (WATCH) pregnancy cohort study. Exploratory factor analysis, univariate logistic regression, and item response theory techniques were used to derive the minimum and most predictive questions for inclusion in the short-form assessment tool. Of the total 49 questionnaire items, 11 items, all 4 body image items, n = 4 attitudes towards weight gain, and n = 3 self-efficacy items, were retained as the strongest predictors of excessive gestational weight gain. These within-scale items were highly correlated, exhibiting high item information function value statistics, and were observed to have high probability (p < 0.05) for excessive gestational weight gain, in the univariate analysis. The short-form questionnaire may assist with the development of tailored health promotion interventions to support women psychologically and physiologically to optimise their pregnancy weight gain. Confirmatory factor analysis is now required.

E-&mHealth interventions targeting nutrition, physical activity, sedentary behavior, and/or obesity among children: A scoping review of systematic reviews and meta-analyses.

Childhood obesity is a public health concern. Electronic and mobile health (e-&mHealth) approaches can facilitate the delivery of interventions for obesity prevention and treatment. Synthesizing reviews of e-&mHealth interventions to improve weight and weight-related behaviors (physical activity, sedentary behavior, and diet) is useful to characterize the current scope of the literature and identify opportunities for future reviews and studies. Using a scoping review methodology, we aimed to evaluate the breadth and methodological quality of systematic reviews and meta-analyses of e-&mHealth interventions targeting weight and weight-related behaviors in children and adolescents aged <19 years. A systematic search of seven databases was conducted, including reviews published between 2000 and 2019. Review characteristics were extracted, and methodological quality was assessed using the AMSTAR 2 tool. Forty-five systematic reviews and meta-analyses were included. All reviews evaluated intervention efficacy (100%), but few assessed other aspects (20% in total) such as cost-effectiveness. Smartphone applications (47%), text messages (44%), and websites (35%) were the main modalities. Weight (60%), physical activity (51%), and diet (44%) were frequently assessed, unlike sedentary behavior (8%). Most reviews were rated as having critically low or low methodological quality (97%). Reviews that identify the effective active ingredients of interventions and explore metrics beyond efficacy are recommended.

Weekend night vs. school night sleep patterns, weight status, and weight-related behaviors among adolescents

ObjectiveIn this study, we examine associations between objectively measured weekend night vs. school night sleep patterns, weight status, and weight-related behaviors among adolescents. DesignCross-sectional study. SettingFive Minnesota high schools that started early (7:30 or 7:45 AM) in Spring 2016. ParticipantsNinth grade students, ages 14.5-16 years (n = 284). MeasurementsStudents completed surveys, had body measurements taken, and wore sleep (wrist) actigraphs for 1 week (n = 284). We examined weekend night-school night differences in sleep duration and sleep timing. We then assessed whether these factors were related to weight status and weight-related behaviors (eating behaviors, food consumption, physical activity, beverage consumption) using generalized linear mixed models. ResultsOn average, students slept 1.5 hours (95% confidence interval 1.3-1.7) more and had a sleep midpoint 1.9 hours (1.8-2.1) later on weekend nights compared to school nights. Female students had larger increases in sleep duration on weekend nights than males but similar timing differences. Sleep duration differences were uncorrelated with sleep timing differences (r = 0.01). Neither duration nor timing differences were associated with overweight, obesity, or any of the eating behaviors we examined. However, sleeping longer on weekend nights than on school nights was associated with lower probability of being active 6-7 days per week (p = .02). ConclusionsAdolescents have substantial sleep duration and sleep timing differences on weekend nights vs. school nights. While these differences may not be associated with weight status or weight-related behaviors, they reflect the reality that most adolescents have schedules that restrict their sleep.

School Safety Among Sexual and Gender Minority Adolescents: Implications for Eating and Weight Control Behaviors.

Unhealthy weight control and disordered eating behaviors are prevalent among adolescents who identify as a gender and/or sexual minority (SGM). The current study examined how perceptions of school safety contribute to reduced negative weight control and eating behaviors across adolescents with diverse sexual and gender identities. Data on perceptions of school safety, as well as negative weight control and disordered eating behaviors (ie, binge eating, eating to cope), were drawn from a large national sample of SGM secondary school students (ie, grades 7-12; N=17,112; LGBTQ National Teen Survey). Differences in negative weight control and disordered eating behaviors emerged as a function of gender identity and sexual orientation. School safety was significantly associated with fewer negative weight control behaviors (B=-0.30, p < .001), reduced binge eating (B=-0.19, p < .001), and less eating to cope (B=-0.21, p < .001). Despite slight variation in the strength of these associations, the protective effects of school safety were significant across sexual and gender identities. Findings suggest that efforts to support feelings of school safety among SGM students are likely to have positive implications for eating and weight-related behaviors, and emphasize the need for interventions to promote climates of safety and inclusion within the school setting.

Urban environment and childhood obesity outcomes and weight-related behaviours in primary school children

BACKGROUND AND AIM: Urban environments are characterised by many factors that may influence children’s lifestyle and increase the risk of childhood obesity, but multiple urban exposure patterns have scarcely been studied. We evaluated the association between multiple urban exposures and childhood obesity outcomes and weight-related behaviours. METHODS: We conducted a cross-sectional study including 2213 children aged 9-12 years in Sabadell, Spain. We estimated air pollution, green spaces, built/food environment, traffic and noise at residential addresses through a total of 28 exposure variables. Childhood obesity outcomes included body mass index (BMI), waist circumference and body fat. Weight-related behaviours included diet (fast food and sugar-sweetened beverage consumption), physical activity, sedentary behaviour, sleep duration and well-being. Associations between exposures and outcomes were estimated in single and multiple-exposure regression models and in a hierarchical clustering on principal components analysis. RESULTS:Forty percent of children were overweight or obese. In single exposure models, very few associations were observed between the urban exposures and obesity outcomes or weight-related behaviours. In multiple exposure models, associations between increased access to unhealthy food environment and higher obesity outcomes became statistically significant (e.g. OR (overweight/obesity status) = 1.20 [95% CI: 1.01; 1.44). Cluster analysis identified 5 clusters of urban exposures. Compared to the most neutral cluster, children in the a priori most harmful cluster (high air pollution, road traffic, and road noise) had a higher BMI and higher odds of overweight/obesity (β (zBMI) = 0.17, [95% CI: 0.01, 0.17]; OR (overweight/obesity) = 1.36, [95% CI: 0.99, 1.85]); the clusters were not associated with the weight-related behaviours. CONCLUSIONS:This study suggests that an urban environment with higher levels of ambient air pollution, traffic and noise is associated with increased childhood obesity risk, but not with weight-related behaviours. A holistic approach capturing urban exposures patterns to evaluate multiple urban exposures is important for future studies KEYWORDS: External exposome, Multi-pollutant/Multi-media, Obesity and metabolic disorders, Children's environmental health
