Characterization of Courtesy Stigma Perceived by Parents of Overweight Children with Bardet-Biedl Syndrome

The Effect of Parent-Targeted Obesity Messaging on Parental Weight Talk Intention: A Randomized Controlled Experiment

It is unknown if parent-targeted health messages about childhood obesity affect parental weight communication with children (e.g., encouraging a child to diet). This randomized, controlled, online experiment assessed the effects of exposure to different message frames on parental intentions to 1) engage in weight communication with their child and, 2) follow the health advice in the message. A diverse sample of U.S. parents (N = 452) were randomly assigned to one of three conditions: 1) a mock news article emphasizing childhood obesity (weight-framed message) with health behavior advice for parents; 2) an article with identical health behavior advice for parents, but framed within the context of improving children's school performance (school-framed message); and 3) a no-treatment control group. Following message exposure, parents completed online surveys assessing their intention to engage in weight communication and the recommended health behaviors. Hierarchical linear regression was used to assess the relationship between experimental condition and the outcome variables. Parents in the weight-frame condition were significantly more likely to report intention to engage in weight communication with their child than parents in the control group, while there was no difference between the school-frame condition and the control group. Parents in both message conditions were equally likely to report intention to adopt the health advice, but parental weight-based self-stigma moderated the relationships. Parent-targeted health advice that features childhood obesity may encourage parents to engage in weight communication with their children. Our findings can inform the development of health messages targeting parents about children's weight-related health.

Global cancer stigma research: a U.S. National Cancer Institute workshop report

Stigma is a social process characterized by negative beliefs, attitudes, and stereotypes associated with a specific attribute or characteristic that leads to discrimination and social exclusion. Stigma manifests across the cancer control continuum and remains a key challenge for cancer prevention and control worldwide. In this commentary, we provide an overview of the U.S. National Cancer Institute's (NCI) Global Cancer Stigma Research Workshop, a multi-disciplinary international conference held virtually in September 2022, which focused on the intersection of cancer and stigma. The meeting was unique in its convening of researchers, advocates, clinicians, and non-governmental and governmental organizations, who-as a collective-provided overarching topics, cross-cutting considerations, and future directions for the cancer stigma research community to consider, which we describe herein. In summary, studying cancer stigma comprehensively requires a holistic, adaptive, and multifaceted approach-and should consider interrelated factors and their intersection within diverse cultural and social contexts worldwide. Collectively, there was a call for: an inclusive approach, encouraging researchers and practitioners to identify and measure cancer stigma as a driver for cancer health inequities globally; an expansion of existing research methodology to include diversity of experiences, contexts, and perspectives; and collaborations among diverse stakeholders to develop more effective strategies for reducing stigma and improving cancer outcomes. Such efforts are essential to cultivating effective and equitable approaches to preventing and treating cancer worldwide.

Bardet-Biedl syndrome: A clinical overview focusing on diagnosis, outcomes and best-practice management

Bardet-Biedl syndrome (BBS) is a genetic disorder characterized by early-onset obesity, polydactyly, genital and kidney anomalies, developmental delay and vision loss due to rod-cone dystrophy. BBS is an autosomal recessive disorder with >20 implicated genes. The genotype-phenotype relationship in BBS is not clear, and there may be additional modifying factors. The underlying mechanism is dysfunction of primary cilia. In BBS, receptor trafficking in and out of the cilia is compromised, affecting multiple organ systems. Along with early-onset obesity, hyperphagia is a prominent symptom and contributes significantly to clinical morbidity and caregiver burden. While there is no cure for BBS, setmelanotide is a new pharmacotherapy approved for treatment of obesity in BBS. The differential diagnosis for BBS includes other ciliopathies, such as Alstrom syndrome, and other genetic obesity syndromes, such as Prader-Willi syndrome. Careful clinical history and genetic testing can help determine the diagnosis and a multidisciplinary team is necessary to guide clinical management.

An Examination of Parental Weight Stigma and Weight Talk Among Socioeconomically and Racially/Ethnically Diverse Parents

Parental communication about body weight can influence children's emotional well-being and eating behaviors. However, little is known about the role of parental self-stigma concerning weight and social position variables (ie, race/ethnicity, income, and gender) in weight communication. This study examined how parents' self-stigmatization for their own weight (ie, weight bias internalization) and self-stigmatization for their child's weight (ie, affiliate stigma) relates to weight talk frequency with their children, and whether these associations vary across parental race/ethnicity, income, and gender. Parents (n = 408) completed a cross-sectional, online survey about their weight communication and self-stigmatization. Linear regression was used to examine the relationships among these variables, including interactions between the stigma variables and social position variables in predicting weight talk. Higher levels of weight bias internalization and affiliate stigma were strongly associated with increased parental weight talk frequency; parents who endorsed higher levels of internalized bias about their own weight expressed greater affiliate stigma for their child's weight, regardless of demographic characteristics or weight status. Associations between the stigma variables and weight talk outcomes were stronger among fathers and parents of higher income. Findings highlight the importance of considering weight stigma variables in parental weight communication research.

Factors contributing to emotional distress when caring for children with imperforate anus: a multisite cross-sectional study in China

Background

Imperforate anus (IA) has a life-long impact on patients and their families. The caregivers of children with IA (CoCIA) might experience distress, which could be detrimental to them physically and mentally. However, there are limitations in the related studies. This study aimed to investigate the prevalence of IA and the associated factors contributing to the distress experienced by CoCIA.

Methods

A cross-sectional study was conducted in three tertiary children's hospitals from November 2018 to February 2019. Distress was assessed using the Chinese version of the Kessler Psychological Distress Scale, and possible determinants were assessed by the Caregiver Reaction Assessment, the Parent Stigma Scale, the Parent Perception of Uncertainty Scale, and the Social Support Scale. Demographic and clinical information was also collected. Multiple regression analysis was performed to explore the association between variables.

Results

Out of 229 CoCIA, 52.9% reported experiencing a high level of distress or above. The data analysis revealed that health problems associated with caregiving, stigma, uncertainty, social support, and children who underwent anal reconstruction surgery 1 year before or earlier could significantly predicate caregivers' distress, and these factors could explain 50.1% of the variance.

Conclusions

The majority of the caregivers of children with IA experience high levels of distress, particularly when their children undergo anal reconstruction surgery 1 year before or earlier. Additionally, health problems related to caregiving, stigma, uncertainty, and low social support could significantly predicate caregivers' distress. It is important for clinical staff to be aware of the prevalent situation of caregivers' distress and to make targeted interventions focused on addressing modifiable factors that should be carried out in family-based care.

Caregiver burden in Bardet-Biedl syndrome: findings from the CARE-BBS study

BACKGROUND

Bardet-Biedl syndrome (BBS) is a rare, genetically heterogeneous obesity syndrome associated with hyperphagia. Given the early onset of BBS symptoms in childhood and multifaceted complications, this study aimed to quantify the caregiver burden associated with BBS.

METHODS

A cross-sectional, multi-country survey of caregivers from the United States (US), United Kingdom (UK), Canada, and Germany was designed to quantify the extent of caregiver burden associated with obesity and hyperphagia symptoms (i.e., uncontrollable hunger) among patients with BBS.

RESULTS

A total of 242 caregivers across the four countries met the inclusion criteria and completed the survey. The mean (standard deviation [SD]) age of the caregivers was 41.9 (6.7) years, and the mean (SD) age of individuals with BBS in their care was 12.0 (3.7) years. Hyperphagia contributed to a BBS diagnosis in 230 of 242 individuals (95.0%). On average, caregivers used eight different weight management approaches for those in their care and expressed a strong desire for more effective weight management methods. Based on the Impacts of Hyperphagia: Caregiver version, patients' hyperphagia had a moderate-to-severe impact on caregiver mood (56.6%), sleep (46.6%), and relationships (48.0%). Caregivers reported experiencing a high level of personal strain (mean [SD], 17.1 [2.9]) and family impact (mean [SD] score, 26.0 [3.8]) due to BBS, as measured by the Revised Impact on Family Scale. Among caregivers in the workforce, there also was high impairment in total work productivity (mean [SD], 60.9% [21.4%]) due to caring for patients with BBS according to the Work Productivity and Activity Impairment. More than half (53%) of the caregivers reported spending over 5,000 out-of-pocket in local currency for medical expenses for the patient with BBS in their care.

CONCLUSIONS

Obesity and hyperphagia have negative impacts on the lives of caregivers of patients with BBS. The burden is demonstrated to be multifaceted, with various components that may interact with and confound each other, including intensive weight management efforts, productivity loses, impaired family dynamics and out-of-pocket medical expenses.

Burden of hyperphagia and obesity in Bardet-Biedl syndrome: a multicountry survey

BACKGROUND

Signs and symptoms of Bardet-Biedl syndrome (BBS) occur during early childhood, progress over time, and place substantial, multifaceted burden on patients and their caregivers. Hyperphagia may be a contributing factor to early-onset obesity in BBS; however, there are limited insights into its impacts on patients and caregivers. We quantified disease burden as it relates to the physical and emotional impacts of hyperphagia in BBS.

METHODS

The CAREgiver Burden in BBS (CARE-BBS) study was a multicountry, cross-sectional survey of adult caregivers of patients with BBS who have had hyperphagia and obesity. The survey consisted of questionnaires including Symptoms of Hyperphagia, Impacts of Hyperphagia, Impact of Weight on Quality of Life (IWQOL)-Kids Parent Proxy, and Patient-Reported Outcome Measurement Information System (PROMIS) v1.0-Global Health 7. In addition, clinical characteristics, medical history, and weight management questions were included. Outcomes were scored and summarized descriptively in aggregate and by country, age, and obesity severity according to weight class.

RESULTS

There were 242 caregivers of patients with BBS who completed the survey. Caregivers observed hyperphagic behaviors throughout the day, with negotiating for food (90%) and waking up and asking or looking for food during the night (88%) being the most frequent. Hyperphagia had at least a moderate negative impact on most patients' mood/emotions (56%), sleep (54%), school (57%), leisure (62%), and familial relationships (51%). Hyperphagia affected concentration at school (78%), and symptoms of BBS contributed to patients missing ≥ 1 day of school a week (82%). Responses from the IWQOL-Kids Parent Proxy suggested obesity most greatly negatively affected physical comfort (mean [standard deviation (SD)], 41.7 [17.2]), body esteem (41.0 [17.8]), and social life (41.7 [18.0]). On the PROMIS questionnaire, mean (SD) global health score for pediatric patients with BBS and overweight or obesity (36.8 [10.6]) was lower than the general population (mean, 50).

CONCLUSIONS

Evidence from this study suggests that hyperphagia and obesity may have broad negative impacts on the lives of patients with BBS, including physical health, emotional well-being, school performance, and personal relationships. Therapies that target hyperphagia may alleviate the extensive clinical and nonclinical impacts experienced by patients with BBS and their caregivers.

Interview-Based Patient- and Caregiver-Reported Experiences of Hunger and Improved Quality of Life with Setmelanotide Treatment in Bardet-Biedl Syndrome

INTRODUCTION

Bardet-Biedl syndrome (BBS) is a rare genetic disease associated with hyperphagia, a pathologic insatiable hunger, due to impaired signaling in the melanocortin-4 receptor (MC4R) pathway. The impact of hyperphagia on the lives of patients with BBS and their families has not been fully characterized.

METHODS

Patients with BBS or their caregivers who participated in clinical trials of the MC4R agonist setmelanotide (NCT03013543 and NCT03746522) were included in this qualitative study. Telephone interviews were conducted using a semistructured interview guide to explore patient experience and caregiver observations of hyperphagia before and during setmelanotide treatment.

RESULTS

Nineteen interviews (8 patients, 11 caregivers) were conducted. The term "hunger" (rather than "hyperphagia") was used in interviews to ensure common terminology. Before setmelanotide treatment, all participants described their (or their child's) hunger as all-consuming, leading to an obsessive focus on food. Nine participants recalled intense, continuous hunger, and most participants (5 patients, 10 caregivers) reported lack of control with eating. Negative impacts on patients' lives included difficulties with concentration, emotional and physical manifestations, and impaired relationships. All participants experienced or observed improvements in hunger and health outcomes during treatment, the most meaningful of which included weight loss and decrease in obsessive focus on food and food-seeking behaviors. All participants reported improvements in either physical and/or emotional well-being and being satisfied with setmelanotide.

CONCLUSIONS

Hyperphagia and resulting food-seeking behaviors have notable negative impacts on quality of life in patients with BBS and caregivers. Setmelanotide improved hyperphagia, reduced body weight and obsessive focus on food, and facilitated improvements in physical and emotional well-being for both patients and caregivers.

Diabetes mellitus in Bardet Biedl syndrome

PURPOSE OF REVIEW

Bardet Biedl syndrome (BBS) is a rare disease characterized by obesity and hyperphagia. Despite the very high prevalence of paediatric and adult obesity in this population, the prevalence of diabetes mellitus is not well described.

RECENT FINDINGS

Studies in small and moderately large cohorts suggest a high prevalence of traditional risk factors for diabetes mellitus in people with BBS. People with BBS appear to have a high prevalence of insulin resistance and metabolic syndrome. Small cohort studies have identified high rates of sleep disordered breathing, including sleep apnoea syndrome. Recent research has characterized traditional behavioural risk factors such as sleep hygiene and physical inactivity in people with BBS. High rates of insufficient sleep and prolonged sedentary time suggest behavioural targets of interventions to treat or prevent diabetes mellitus. Hyperphagia, likely caused by defects in the hypothalamic melanocortin-4 receptor (MC4R) neuronal pathway, pose additional challenges to behavioural interventions to prevent diabetes mellitus.

SUMMARY

Understanding the prevalence of diabetes mellitus and other metabolic disorders in people with BBS and the impact of traditional risk factors on glucose regulation are important to developing effective treatments in this population.

Bardet-Biedl Syndrome: Current Perspectives and Clinical Outlook

The Bardet Biedl syndrome (BBS) is a rare inherited disorder considered a model of non-motile ciliopathy. It is in fact caused by mutations of genes encoding for proteins mainly localized to the base of the cilium. Clinical features of BBS patients are widely shared with patients suffering from other ciliopathies, especially autosomal recessive syndromic disorders; moreover, mutations in cilia-related genes can cause different clinical ciliopathy entities. Besides the best-known clinical features, as retinal degeneration, learning disabilities, polydactyly, obesity and renal defects, several additional clinical signs have been reported in BBS, expanding our understanding of the complexity of its clinical spectrum. The present review aims to describe the current knowledge of BBS i) pathophysiology, ii) clinical manifestations, highlighting both the most common and the less described features, iii) current and future perspective for treatment.

Quality of life improvements following one year of setmelanotide in children and adult patients with Bardet-Biedl syndrome: phase 3 trial results

BACKGROUND

Bardet-Biedl syndrome is a rare genetic disease associated with hyperphagia and early-onset, severe obesity. There is limited evidence on how hyperphagia and obesity affect health-related quality of life in patients with Bardet-Biedl syndrome, and on how management of these symptoms may influence disease burden. This analysis evaluated changes in health-related quality of life in adults and children with Bardet-Biedl syndrome in a Phase 3 trial following 1 year of setmelanotide treatment (ClinicalTrials.gov identifier: NCT03746522).

METHODS

Patients with Bardet-Biedl syndrome and obesity received 52 weeks of treatment with setmelanotide and completed various self-reported health-related quality of life measures. Patients aged < 18 years or their caregiver completed the Pediatric Quality of Life Inventory (PedsQL; meaningful improvement, 4.4-point change); adults aged ≥ 18 years completed the Impact of Weight on Quality of Life Questionnaire-Lite (IWQOL-Lite; meaningful improvement range, 7.7-12-point change). Descriptive outcomes were reported in patients with data both at active treatment baseline and after 52 weeks of treatment.

RESULTS

Twenty patients (< 18 years, n = 9; ≥ 18 years, n = 11) reported health-related quality of life at baseline and 52 weeks. For children and adolescents, PedsQL score mean change from baseline after 52 weeks was + 11.2; all patients with PedsQL impairment at baseline (n = 4) experienced clinically meaningful improvement. In adults, IWQOL-Lite score mean change from baseline was + 12.0. Of adults with IWQOL-Lite impairment at baseline (n = 8), 62.5% experienced clinically meaningful improvement. In adults, IWQOL-Lite score was significantly correlated with changes in percent body weight (P = 0.0037) and body mass index (P = 0.0098).

CONCLUSIONS

After 1 year of setmelanotide, patients reported clinically meaningful improvements across multiple health-related quality of life measures. This study highlights the need to address the impaired health-related quality of life in Bardet-Biedl syndrome, and supports utility of setmelanotide for reducing this burden.

Parents of Children With High Weight Are Viewed as Responsible for Child Weight and Thus Stigmatized

Courts in seven U.S. states have removed children with "obesity" from parental custody until children could maintain "healthy weights." These rulings-alongside qualitative reports from parents of children with high weight (PoCHs)-suggest that PoCHs are judged as bad parents. Yet little work has tested whether people genuinely stigmatize PoCHs or what drives this phenomenon. In three experiments with U.S. online community participants (N = 1,011; two preregistered), we tested an attribution theory model: Social perceivers attribute children's weights to parents and thus stigmatize those parents. Experiments 1 and 2 support this model (across parent and child gender). Experiment 3 manipulated attributions of parental responsibility for child weight, revealing attenuated stigma with low attributions of responsibility. Findings are among the first to describe and explain stigma toward a large demographic (parents of children with obesity)-with real-world implications (e.g., for family separation, health care)-and may additionally illuminate the psychology underlying stigma toward parents of children with other potentially stigma-evoking identities.

Monitoring and Management of Bardet-Biedl Syndrome: What the Multi-Disciplinary Team Can Do

Bardet – Biedl syndrome is a rare autosomal recessive multisystem non-motile ciliopathy. It has heterogeneous clinical manifestations. It is caused by mutations in 26 genes encoding BBSome proteins, chaperonines, and IFT complex. The main clinical features are: retinal cone-rod dystrophy, central obesity, postaxial polydactyly, cognitive impairment, hypogonadism and genitourinary anomalies, and kidney disease. The onset of clinical manifestations is variable which makes the diagnosis difficult in some patients. Because of the multiple system involvement, a multidisciplinary approach is necessary. The purpose of this review is to provide monitoring and management directions for a better approach to these patients.

Weight Stigma by Association Among Parents of Children With Obesity: A Randomized Trial

OBJECTIVE

To experimentally test weight stigma and weight stigma by association in a parent-child relationship using a large, community-based sample.

METHODS

We conducted a randomized experiment on Amazon Mechanical Turk using an online survey. Participants were randomly assigned to view a picture of a parent-child dyad, for which the parent and child's gender (male vs. female) and weight status (with obesity vs. without obesity) were manipulated. Participants read identical parenting descriptions that adhered to the American Academy of Pediatrics' parenting recommendations, then rated the parent's perceived effectiveness, helpfulness, and level of caring using a parenting questionnaire based on Barnhart et al (2013).

RESULTS

Participants (N = 1862; Mage = 36.8 [11.2] years) rated parents of children with obesity as less effective compared to parents of children without obesity (P = .010) and parents with obesity as less effective compared to parents without obesity (P = .033). Participants also rated parents with obesity as less helpful compared to parents without obesity (P = .021). No differences emerged in perceived caring. Parenting evaluations did not differ across daughters versus sons or mothers versus fathers.

CONCLUSIONS

Parents of children with obesity may experience weight stigma by association, which could have direct consequences for the parents, the children, and the parent-child relationship.

Courtesy stigma of parents of children with Down syndrome: Adaptation process and transcendent stage

Courtesy stigma, which arises from close connections to people with stigmatized characteristics, negatively affects interpersonal relations. This study aimed to evaluate courtesy stigma and the adaptation process of parents of children with Down syndrome based on semi-structured interviews with 23 Japanese parents. The interview themes were (a) negatively perceived interpersonal experiences and coping strategies; (b) information disclosure and others' responses; and (c) positively perceived interpersonal experiences. The interview data were transcribed and analyzed based on a grounded theory approach. The results suggested that parents perceived and experienced multidimensional courtesy stigma, and they used various coping strategies categorized in combinations of passive-active and internal-external. All parents disclosed information about their child's diagnosis to others, and reverse disclosure (i.e., revealing own relations with people with disabilities) was characteristically observed thereafter. Through active interaction and reflection, the parents cultivated social relationships, compassion, world views, and community involvement, which led to the transcendent stage. However, internal conflict as a mediator between people with and without Down syndrome re-emerged even after achieving the transcendent stage. These findings could help to develop interventions in genetic counseling for parents to deal with interpersonal relationship difficulties.

Clarification of stigma concepts in research with families of individuals with neurodevelopmental disabilities

Stigma concepts among families of individuals with neurodevelopmental disabilities have received increased attention from researchers in the past decade. With a growing number of studies published, there are also notable discrepancies in conceptualizations and uses of stigma terms among scholars. These variations may result in inadequate comparisons of findings across studies and a failure to generalize the results. Therefore, I have compared various stigma concepts and offered key features of each term as well as suggested methodology for facilitating stigma research.

Experiences of weight stigma in adolescents with severe obesity and their families

AIM

To describe the experiences of weight stigma in adolescents with severe obesity and their parents.

DESIGN

Qualitative descriptive secondary analysis.

METHODS

A secondary analysis on 31 transcripts from a larger study of 46 transcripts conducted between February 2019 and June 2020. Semi-structured interviews were conducted with 19 parents (n = 17 mothers, n = 2 fathers) and 12 adolescents (n = 7 male, n = 5 female). Interviews were digitally audio recorded, transcribed and analysed using conventional content analysis.

RESULTS

Four common themes were identified reflecting experiences of weight stigma: weight-based teasing and bullying, interactions with healthcare providers (HCPs), family interactions and blame. Subthemes were fairness and impact on mental health.

CONCLUSION

This secondary analysis adds to the sparse literature documenting the experiences of weight stigma from adolescents with severe obesity and their families. It is important to understand the experiences of weight stigma from the adolescent and parent perspective as it can inform healthcare, education and policies across communities and facilitate holistic health for this vulnerable population.

IMPACT

The need for research to better understand how experiences of weight stigma correlate with physiological and psychological outcomes and inform innovative interventions are critical to improve treatment of severe obesity. Healthcare providers across disciplines are in a strategic position to change the paradigm through which we provide care to youth with severe obesity and guide families in supporting their children's weight management efforts without contributing to weight stigma.

Sleep and physical activity patterns in adults and children with Bardet-Biedl syndrome

Background

Overweight and obesity are common features of the rare disease Bardet–Biedl syndrome (BBS). Sleep and physical activity are behaviors that might impact overweight and obesity and thus may play a key role in the health and well-being of people with BBS. Objectively-measured sleep and physical activity patterns in people with BBS are not well known. We evaluated objectively-measured sleep and physical activity patterns in the largest cohort to date of people with BBS.

Results

Short sleep duration, assessed using wrist-worn accelerometers, was common in both children and adults with BBS. Only 7 (10%) of adults and 6 (8%) of children met age-specific sleep duration recommendations. Most adults 64 (90%) achieved recommended sleep efficiency. The majority of children 26 (67%) age 6–12 years achieved recommended sleep efficiency, but among children age 13–18, only 18 (47%). In both adults and children, sleep duration was significantly negatively correlated with duration of prolonged sedentary time. In children age 6–12 sleep duration was also significantly related to total activity score, children with lower sleep duration had lower total activity scores.

Conclusions

Insufficient sleep duration is very common in people with BBS. Prolonged sedentary time and short sleep duration are both potentially important health-related behaviors to target for intervention in people with BBS.

Bardet-Biedl syndrome: Weight patterns and genetics in a rare obesity syndrome

BACKGROUND

Bardet-Biedl syndrome (BBS) is a rare genetic disorder that severely inhibits primary cilia function. BBS is typified by obesity in adulthood, but pediatric weight patterns, and thus optimal periods of intervention, are poorly understood.

OBJECTIVES

To examine body mass differences by age, gender, and genotype in children and adolescents with BBS.

METHODS

We utilized the largest international registry of BBS phenotypes. Anthropometric and genetic data were obtained from medical records or participant/family interviews. Participants were stratified by age and sex categories. Genotype and obesity phenotype were investigated in a subset of participants with available data.

RESULTS

Height and weight measurements were available for 552 unique individuals with BBS. The majority of birth weights were in the normal range, but rates of overweight or obesity rapidly increased in early childhood, exceeding 90% after age 5. Weight z-scores in groups >2 years were above 2.0, while height z-scores approached 1.0, but were close to 0.0 in adolescents. Relative to those with the BBS10 genotype, the BBS1 cohort had a lower BMI z-score in the 2-5 and 6-11 age groups, with similar BMI z-scores thereafter. Children with biallelic loss of function (LOF) genetic variants had significantly higher BMI z-scores compared to missense variants.

CONCLUSION

Despite normal birth weight, most individuals with BBS experience rapid weight gain in early childhood, with high rates of overweight/obesity sustained through adolescence. Children with LOF variants are disproportionally affected. Our findings support the need for earlier recognition and initiation of weight management therapies in BBS.

"I Feel Like Less of a Mom": Experiences of Weight Stigma by Association among Mothers of Children with Overweight and Obesity

Background: Parents of children with higher weight are blamed and shamed for their children's weight. However, parents' experiences of this form of stigma, termed weight stigma by association, are poorly understood. The objective of this study was to investigate the sources, forms, and impacts of weight stigma by association among mothers of children with overweight or obesity. Methods: In this qualitative study, mothers who reported concern about their children's weight participated in semistructured interviews administered by the research team. A coding scheme was developed and reliably applied to interview transcripts. Mothers' self-reported sociodemographic information, and height and weight were measured. Results: Thirty-four mothers (Mage: 43.4 years; 26.5% non-Hispanic Black or African American, 70.6% with obesity) participated in the study. Mothers reported that family members were a common source of negative comments about their children's weight; these comments were often critical of mothers' parenting and in some cases contributed to negative affect among mothers. Many mothers also reported negative experiences during children's physicians' visits as a result of their children's weight. Almost all mothers expressed guilt and sadness for their perceived role in their children's weight status, expressing regret that they did not parent differently. Conclusions: Mothers of children with overweight and obesity are frequently the target of weight stigma by association and experience negative cognitions and emotions regarding their perceived role in their children's weight. Continued research is needed to elucidate the impacts of stigma by association due to child weight on parents' health, the parent/child relationship, and children's health.

Who's a good boy? Effects of dog and owner body weight on veterinarian perceptions and treatment recommendations

Background:

Weight bias against persons with obesity impairs health care delivery and utilization and contributes to poorer health outcomes. Despite rising rates of pet obesity (including among dogs), the potential for weight bias in veterinary settings has not been examined.

Subjects/Methods:

In two online, 2×2 experimental studies, the effects of dog and owner body weight on perceptions and treatment recommendations were investigated in 205 practicing veterinarians (Study 1) and 103 veterinary students (Study 2). In both studies, participants were randomly assigned to view one of four vignettes of a dog and owners with varying weight statuses (lean vs. obesity). Dependent measures included emotion/liking ratings toward the dog and owners; perceived causes of the dog’s weight; and treatment recommendations and compliance expectations. Other clinical practices, such as terms to describe excess weight in dogs, were also assessed.

Results:

Veterinarians and students both reported feeling more blame, frustration, and disgust toward dogs with obesity and their owners than toward lean dogs and their owners (p values<0.001). Interactions between dog and owner body weight emerged for perceived causes of obesity, such that owners with obesity were perceived as causing the dog with obesity’s weight, while lean owners were perceived as causing the lean dog’s weight. Participants were pessimistic about treatment compliance from owners of the dog with obesity, and weight loss treatment was recommended for the dog with obesity when presenting with a medical condition ambiguous in its relationship to weight. Veterinarians and students also reported use of stigmatizing terms to describe excess weight in dogs.

Conclusions:

Findings from this investigation, with replication, have implications for training and practice guidelines in veterinary medicine.

Caring for a child with Bardet-Biedl syndrome: A qualitative study of the parental experiences of daily coping and support

This study aimed to explore the parental experiences of having a child with Bardet-Biedl syndrome (BBS) and how parents managed to cope with this situation. Five parents of children with BBS (0-18 years old) participated in semistructured in-depth interviews. Inductive thematic analysis was used to identify themes. The parents experienced distress due to a lack of knowledge on BBS in their support system (e.g., school staff, clinicians, and family members), and they found it stressful to coordinate with multiple support services. Socialization at work, support from family members, and communicating with other parents who are in a similar situation promoted better coping and adaptations to daily life. Results highlight the importance of parents receiving adequate support while they face daily challenges. An increased knowledge on how rare disorders impact family life is needed in the support system.

Relationships between Stigma, Social Support, and Distress in Caregivers of Chinese Children with Imperforate Anus: A Multicenter Cross-Sectional Study

PURPOSE

This study was conducted to explore the relationships between stigma, social support, and distress in caregivers of children with imperforate anus (IA) and determine whether social support mediates the relationship between stigma and distress.

DESIGN AND METHODS

This cross-sectional study was conducted in three tertiary children's hospitals in Eastern China. Primary caregivers completed the Social Support Scale and the Chinese versions of the Parent Stigma Scale and Kessler Psychological Distress Scale, and provided their demographic information. The children's demographic and clinical data were also collected. The hypothesized relations were explored using structural equation modeling via the bootstrap method.

RESULTS

A total of 229 caregivers were enrolled. Distress was positively associated with stigma (r = 0.396, P < 0.01) and negatively associated with social support (r = -0.413, P < 0.01) in all dimensions (r = 0.314-0.346, P < 0.01). Stigma was also negatively correlated with social support (r = 0.280, P < 0.01). Furthermore, social support could partially mediate the relationship between stigma and distress (b = 0.135; 95% confidence interval: 0.072, 0.233).

CONCLUSIONS

Stigma can increase caregivers' distress, while social support can reduce it. Stigma can also negatively influence caregivers' social support. Therefore, stigma should be mitigated to enhance caregivers' social support and decrease their distress.

PRACTICE IMPLICATIONS

The study findings may aid in the identification of the psychological status of caregivers of children with IA, and also inform targeted intervention programs.

Stigma: A biocultural proposal for integrating evolutionary and political-economic approaches

OBJECTIVES

Stigma-the process by which people become socially discredited because they hold a characteristic that is classified as unacceptable or undesirable-has barely been considered in biocultural analyses. Yet, it provides an acute point of articulation for evolutionary and political-economic perspectives on human variation, including the biocultural production of health disparities. To explain the theoretical integration of the two perspectives to stigma, we first lay out some operationalizable definitions of stigma, and review feasible methods to capture them in the field. We then test the roles of predictors suggested from evolutionary (respondent's level of disgust, fear of contagion) and political-economic (respondent's perceived social standing and negative social labeling of those who violate hygiene norms) theories of stigma.

METHODS

We used survey, interview, and behavioral report data from a study of hygiene behaviors at four local community sites in Guatemala, Fiji, New Zealand, and the United States (N = 300). We applied a hierarchical GLMM design that treats site as a random effect.

RESULTS

The independent influences of both variable sets are evident in publicly visible forms of reported hygiene behaviors, specifically the exhibition of clean bodies, clothes, and homes.

CONCLUSION

We propose that the study of stigma provides a productive operationalizable space to engage the promise of the biocultural synthesis to integrate evolutionary and political-economic models of health and human variation.

Abandoning Medical Authority: When Medical Professionals Confront Stigmatized Adolescent Sex and the Human Papillomavirus (HPV) Vaccine

Despite authority's centrality to the medical profession, providers routinely forgo their medical authority during clinical encounters. Research focuses on patients challenging medical authority but indicates these confrontations are uncommon and providers seldom relinquish their authority in response. Using rare data of 75 audio recordings of adolescent vaccine discussions during clinical encounters and interviews with and observations of medical staff, I examine how staff leverage or abandon their medical authority to convince parents to vaccinate. I find medical professionals use less authority when at risk of stigmatizing patients: Medical professionals are less authoritative when recommending human papillomavirus (HPV) vaccination versus other adolescent vaccines, particularly when addressing the need to vaccinate before sexual onset due to concerns of labeling the child as sexually active. Medical staff defer to parents in ways that potentially discourage HPV vaccine uptake: They encourage HPV vaccination less than other vaccines and infrequently challenge parents' sex-related reasons for vaccine refusal.

Intergenerational Association of Maternal Obesity and Child Peer Victimization in the United States

Drawing on the intergenerational stress proliferation theory, the courtesy stigma thesis, and the buffering ethnic culture thesis, this study examines the association between maternal obesity and child's peer victimization and whether this association varies for white and black children. Based on longitudinal data from a nationally representative sample of mother-child pairs in the U.S. Panel Study of Income Dynamics Child Development Supplement, negative binomial models show that maternal obesity is associated with increased frequency of peer victimization, even after controlling for family socioeconomic status, child weight status, health status, self-esteem, and demographic characteristics. The association was significant only for white children. Given the developmental significance of child peer relations and the social disparities in obesity, future studies need to explicitly test causal mechanisms underlying the association to decide whether obesity may function as a family stressor (versus an individual stressor) that contributes to the intergenerational reproduction of inequality.

Bad news: Families' experiences and feelings surrounding the diagnosis of Zika-related microcephaly

The rapidly increasing number of cases of Zika virus and limited understanding of its congenital sequelae (e.g., microcephaly) led to stories of fear and uncertainty across social media and other mass communication networks. In this study, we used techniques generic to netnography, a form of ethnography, using Internet-based computer-mediated communications as a source of data to understand the experience and perceptions of families with infants diagnosed with Zika-related microcephaly. We screened 27 YouTube™ videos published online between October 2015 and July 2016, during which the Zika epidemic started, peaked, and declined. We identified three themes: (a) experiencing the news of a diagnosis of Zika-associated microcephaly; (b) experiencing feelings and expectations of the 'imperfect' child; and (c) seeking to understand microcephaly to care for the child. We found that families experienced distressing feelings of shock, sadness, hopelessness, and pain, while dealing with emerging and sometimes conflicting information being transmitted by news outlets, uncertainty about the child's health, and healthcare providers' lack of clarity to guide the family members. The 'unknown' factor of ZIKA was an additional stressful factor in the experience of the families.

Managing Bardet-Biedl Syndrome-Now and in the Future

Bardet-Biedl syndrome is a rare autosomal recessive multisystem disorder caused by defects in genes encoding for proteins that localize to the primary cilium/basal body complex. Twenty-one disease-causing genes have been identified to date. It is one of the most well-studied conditions in the family of diseases caused by defective cilia collectively known as ciliopathies. In this review, we provide an update on diagnostic developments, clinical features, and progress in the management of Bardet-Biedl syndrome. Advances in diagnostic technologies including exome and whole genome sequencing are expanding the spectrum of patients who are diagnosed with Bardet-Biedl syndrome and increasing the number of cases with diagnostic uncertainty. As a result of the diagnostic developments, a small number of patients with only one or two clinical features of Bardet-Biedl syndrome are being diagnosed. Our understanding of the syndrome-associated renal disease has evolved and is reviewed here. Novel interventions are developing at a rapid pace and are explored in this review including genetic therapeutics such as gene therapy, exon skipping therapy, nonsense suppression therapy, and gene editing. Other non-genetic therapies such as gene repurposing, targeted therapies, and non-pharmacological interventions are also discussed.

Courtesy stigma: A concealed consternation among caregivers of people affected by leprosy

This study explored experiences of courtesy stigma among caregivers of people affected by leprosy. Using a qualitative research approach, twenty participants were purposively selected and in-depth interviews conducted. The interviews were audio-recorded, transcribed, and analyzed to identify emerging themes that addressed objectives of the study. The findings indicated that caregivers of people affected by leprosy experienced courtesy stigma. Evidence showed that fear of contagion underpinned caregivers' experiences, especially in employment and romantic relationships. In addition, participants adopted different strategies (disregarding, concealment, education, faith-based trust) to handle courtesy stigma. The findings demonstrate that psychosocial support and financial assistance to caregivers are necessary considerations for attainment of effective care for people affected by leprosy.

Walking in the shoes of caregivers of children with obesity: supporting caregivers in paediatric weight management

To incorporate the perspectives and experiences of family caregivers of children with obesity, the KidFit Health and Wellness Clinic, a paediatric weight management programme, embedded feedback opportunities into various stages of programme development. Caregivers were eligible to participate if their children had completed initial 4-week group-based pilot programming or were currently receiving treatment in 10 or 12 week group-based programming. Data were collected through feedback session discussions, audio-recorded, transcribed verbatim and analysed thematically. In total, 6 caregivers participated in the pilot group feedback session and 32 caregivers participated in the structured group feedback sessions. Caregivers reported that healthy lifestyle strategies first communicated by clinic staff to children during group sessions provided expert validation and reinforcement when discussing similar messages at home. Caregivers reported feeling isolated and blamed for causing their children's obesity and appreciated the supportive forum that group-based programming provided for sharing experiences. Since experiences of blame and isolation can burden caregivers of children with obesity, paediatric weight management programmes might consider including peer support opportunities and discussion forums for ongoing social support in addition to education about lifestyle change.

The association between parent-reported provider communication quality and child obesity status: Variation by parent obesity and child race/ethnicity

OBJECTIVE

To examine the association between healthcare provider communication quality and child obesity status, and the role of parent obesity and child race/ethnicity regarding this association.

METHODS

We conducted a cross-sectional secondary data analysis with the 2011-2013 Medical Expenditures Panel Survey of parents with children ages 6-12 (n=5390). We used multivariable logistic regression to examine the association of parent-reported healthcare provider communication quality (explaining well, listening carefully, showing respect, and spending enough time) with child obesity status, and effect modification by parent obesity and child race/ethnicity.

RESULTS

Parents of obese children were more likely to report that their child's healthcare provider listened carefully (OR=1.41, p=0.002) and spent enough time (OR=1.33, p=0.022) than parents of non-obese children. Non-obese parents of obese children experienced better communication in the domains of listening carefully (p<0.001) and spending enough time (p=0.007). Parents of obese non-Hispanic Asian children and non-Hispanic Black children were more likely to report that providers explained things well (p=0.043) and listened carefully (p=0.012), respectively.

CONCLUSION

Parents of obese children experienced better communication if parents were non-obese or children were non-Hispanic Black or Asian.

PRACTICE IMPLICATIONS

Healthcare providers should ensure effective communication with obese parents of obese children.

Anticipated stigma and blameless guilt: Mothers' evaluation of life with the sex-linked disorder, hypohidrotic ectodermal dysplasia (XHED)

Practical experience of a genetic disorder may influence how parents approach reproduction, if they know their child may be affected by an inherited condition. One important aspect of this practical experience is the stigmatisation which family members may experience or witness. We outline the concept of stigma and how it affects those in families with a condition that impacts upon physical appearance. We then consider the accounts given by females in families affected by the rare sex-linked disorder, X-linked hypohidrotic ectodermal dysplasia (XHED), which principally affects males but can be passed through female carriers to affect their sons. The stigmatisation of affected males is as important in the accounts given by their womenfolk as the physical effects of the condition; this impacts on their talk about transmission of the disorder to the next generation. Perspectives may also change over time. The mothers of affected sons differ from their daughters, who do not yet have children, and from their mothers, who may express more strongly their sense of guilt at having transmitted the condition, despite there being no question of moral culpability. We conclude with suggestions about other contexts where the possibility of stigma may influence reproductive decisions.
