Physical activity and sleep changes among children during the COVID-19 pandemic.

Daily routines, including in-person school and extracurricular activities, are important for maintaining healthy physical activity and sleep habits in children. The COVID-19 pandemic significantly disrupted daily routines as in-person school and activities closed to prevent spread of SARS-CoV-2. We aimed to examine and assess differences in objectively measured physical activity levels and sleep patterns from wearable sensors in children with obesity before, during, and after a period of school and extracurricular activity closures associated with the COVID-19 pandemic. We compared average step count and sleep patterns (using the Mann-Whitney U Test) before and during the pandemic-associated school closures by using data from activity tracker wristbands (Garmin VivoFit 3). Data were collected from 94 children (aged 5-17) with obesity, who were enrolled in a randomized controlled trial testing a community-based lifestyle intervention for a duration of 12-months. During the period that in-person school and extracurricular activities were closed due to the COVID-19 pandemic, children with obesity experienced objectively-measured decreases in physical activity, and sleep duration. From March 15, 2020 to March 31, 2021, corresponding with local school closures, average daily step count decreased by 1655 steps. Sleep onset and wake time were delayed by about an hour and 45 min, respectively, while sleep duration decreased by over 12 min as compared with the pre-closure period. Step counts increased with the resumption of in-person activities. These findings provide objective evidence for parents, clinicians, and public health professionals on the importance of in-person daily activities and routines on health behaviors, particularly for children with pre-existing obesity. Trial Registration: Clinical trial registration: NCT03339440.

Experimental Therapeutics: Opportunities and Challenges Stemming From the National Institute of Mental Health Workshop on Novel Target Discovery and Psychosocial Intervention Development.

There has been slow progress in the development of interventions that prevent and/or reduce mental-health morbidity and mortality. The National Institute of Mental Health (NIMH) launched an experimental-therapeutics initiative with the goal of accelerating the development of effective interventions. The emphasis is on interventions designed to engage a target mechanism. A target mechanism is a process (e.g., behavioral, neurobiological) proposed to underlie change in a defined clinical endpoint and through change in which an intervention exerts its effect. This article is based on discussions from an NIMH workshop conducted in February 2020 and subsequent conversations among researchers using this approach. We discuss the components of an experimental-therapeutics approach such as clinical-outcome selection, target definition and measurement, intervention design and selection, and implementation of a team-science strategy. We emphasize the important contributions of different constituencies (e.g., patients, caregivers, providers) in deriving hypotheses about novel target mechanisms. We highlight strategies for target-mechanism identification using published and hypothetical examples. We consider the decision-making dilemmas that arise with different patterns of results in purported mechanisms and clinical outcomes. We end with considerations of the practical challenges of this approach and the implications for future directions of this initiative.

Intervening on Social Comparisons on Social Media: Electronic Daily Diary Pilot Study.

BACKGROUND: Literature has underscored the dark aspects of social media use, including associations with depressive symptoms, feelings of social isolation, and diminished self-esteem. Social comparison, the process of evaluating oneself relative to another person, is thought to contribute to these negative experiences such that people with a stronger tendency to compare themselves with others are particularly susceptible to the detrimental effects of social media. Social media as a form of social connection and communication is nevertheless an inevitable-and arguably integral-part of life, particularly for young adults. Therefore, there is a need to investigate strategies that could alter the manner in which people interact with social media to minimize its detrimental effects and maximize the feelings of affiliation and connection. OBJECTIVE: This pilot study examined the feasibility, acceptability, and effectiveness of a brief web-based intervention designed to alter engagement with social media and promote psychological well-being by encouraging social savoring as an alternative to social comparison. Social savoring was operationalized as experiencing joyful emotions related to the happiness of someone else's experiences (ie, feeling happy for someone else). METHODS: Following an intensive longitudinal design, 55 college students (mean age 19.29, SD 0.93 years; n=43, 78% women and n=23, 42% White) completed baseline measures (individual differences, psychological well-being, connectedness, and social media use) and then 14 days of daily surveys on their social media activity and well-being. On day 8, the group that was randomized to receive the intervention watched a video instructing them on the skill of social savoring and was asked to practice this skill during days 8 to 14. RESULTS: Overall, participants reported positive perceptions of the intervention. Participants who watched the intervention video reported significantly higher performance self-esteem (P=.02) at posttest than those in the control condition, after controlling for baseline levels. Participants also reported significantly higher state self-esteem (P=.01) on days in which they engaged in more social savoring while using social media, and the use of social savoring increased significantly (P=.01) over time, suggesting that participants found it helpful. Participants in both conditions reported significantly lower levels of social comparison (control: P=.01; intervention: P=.002) and higher levels of connectedness (control: P<.001; intervention: P=.001) at posttest than at baseline. CONCLUSIONS: Initial evidence from this pilot study suggests that a web-based social savoring intervention may help minimize the potentially harmful consequences of social media use, at least in some domains. Future work is needed to examine the effectiveness and acceptance of this intervention in different age groups and in clinical samples that are in part characterized by higher levels of comparison with others (eg, people with eating disorders).

Examination of perfectionism and self-concept constructs across stages of eating disorder recovery in men: An exploratory study.

OBJECTIVE: This study examined perfectionism and self-concept constructs across eating disorder recovery stages in men, using a conceptualization of recovery that encompasses physical, behavioral, and cognitive recovery. METHOD: Participants were 35 men with an eating disorder history (Mage = 26.60 years, SD = 10.81), categorized as in full recovery, in partial recovery, or with a current eating disorder diagnosis/pathology, and 27 men with no eating disorder history (controls; Mage = 26.44 years, SD = 10.08). Data for determining recovery status were collected from surveys, interviews, and measured weight and height; perfectionism and self-concept were assessed via surveys. RESULTS: Among the perfectionism constructs, the greatest magnitude of effect sizes involving the fully recovered group was for socially prescribed perfectionism where this group had lower levels of perfectionism than the eating disorder diagnosis/pathology group (Hedge's g = -1.72) or the partially recovered group (Hedge's g = -1.56). For the self-concept constructs, effect sizes involving the fully recovered group and the other recovery status groups were all large (absolute values: 0.76-1.58) and reflected a large magnitude of difference with fully recovered men having higher self-esteem and self-efficacy and lower social comparison than men with a current eating disorder diagnosis or pathology or those partially recovered. CONCLUSION: Full recovery in men was associated with healthy self-concept constructs and with low socially prescribed perfectionism. Future research with larger samples should seek to replicate these findings and, using a longitudinal design, examine these constructs as potential predictors or maintenance factors of comprehensive eating disorder recovery in men.

Experiences of mimicry in eating disorders.

BACKGROUND: People unknowingly mimic the behaviors of others, a process that results in feelings of affiliation. However, some individuals with eating disorders describe feeling "triggered" when mimicked. This study explores the effects of implicit non-verbal mimicry on individuals with a history of an eating disorder (ED-His) compared to healthy controls (HCs). METHOD: Women (N = 118, nED-His = 31; Mage = 21 years) participated in a laboratory task with a confederate trained to either discreetly mimic (Mimicry condition) or not mimic (No-Mimicry condition) the mannerisms of the participant. Participants rated the likability of the confederate and the smoothness of the interaction. RESULTS: Participants in the No-Mimicry condition rated the confederate as significantly more likable than in the Mimicry condition, and ED-His rated the confederate as more likable than HCs. ED-His in the Mimicry condition rated the interaction as less smooth than HCs, whereas this pattern was not found in the No-Mimicry condition. Among ED-His, longer disorder duration (≥ 3.87 years) was associated with less liking of a confederate who mimicked and more liking of a confederate who did not mimic. CONCLUSIONS: We discuss the implications of these findings for interpersonal therapeutic processes and group treatment settings for eating disorders. Our study on subtle, nonverbal mimicry revealed differences in social behavior for women with a history of an eating disorder compared to healthy women. For participants with an eating disorder history, a longer duration of illness was associated with a worse pattern of affiliation, reflected in lower liking of a mimicker. Further research on how diverging processes of affiliation may function to perpetuate the chronicity of eating disorders and implications for treatment is needed.

Shuffle the Decks: Children Are Sensitive to Incidental Nonrandom Structure in a Sequential-Choice Task.

As children age, they can learn increasingly complex features of environmental structure-a key prerequisite for adaptive decision-making. Yet when we tested children (N = 304, 4-13 years old) in the Children's Gambling Task, an age-appropriate variant of the Iowa Gambling Task, we found that age was negatively associated with performance. However, this paradoxical effect of age was found only in children who exhibited a maladaptive deplete-replenish bias, a tendency to shift choices after positive outcomes and repeat choices after negative outcomes. We found that this bias results from sensitivity to incidental nonrandom structure in the canonical, deterministic forms of these tasks-and that it would actually lead to optimal outcomes if the tasks were not deterministic. Our results illustrate that changes in decision-making across early childhood reflect, in part, increasing sensitivity to environmental structure.

Complex functional brain network properties in anorexia nervosa.

BACKGROUND: Anorexia nervosa (AN) is a disorder characterized by an incapacitating fear of weight gain and by a disturbance in the way the body is experienced, facets that motivate dangerous weight loss behaviors. Multimodal neuroimaging studies highlight atypical neural activity in brain networks involved in interoceptive awareness and reward processing. METHODS: The current study used resting-state neuroimaging to model the architecture of large-scale functional brain networks and characterize network properties of individual brain regions to clinical measures. Resting-state neuroimaging was conducted in 62 adolescents, 22 (21 female) with a history of AN and 40 (39 female) healthy controls (HCs). Sensorimotor and basal ganglia regions, as part of a 165-region whole-brain network, were investigated. Subject-specific functional brain networks were computed to index centrality. A contrast analysis within the general linear model covarying for age was performed. Correlations between network properties and behavioral measures were conducted (significance q < .05). RESULTS: Compared to HCs, AN had lower connectivity from sensorimotor regions, and greater connectivity from the left caudate nucleus to the right postcentral gyrus. AN demonstrated lower sensorimotor centrality, but higher basal ganglia centrality. Sensorimotor connectivity dyads and centrality exhibited negative correlations with body dissatisfaction and drive for thinness, two essential features of AN. CONCLUSIONS: These findings suggest that AN is associated with greater communication from the basal ganglia, and lower information propagation in sensorimotor cortices. This is consistent with the clinical presentation of AN, where individuals exhibit patterns of rigid habitual behavior that is not responsive to bodily needs, and seem "disconnected" from their bodies.

Individuals with anorexia nervosa (AN) usually report a fear of gaining weight. They often develop a dislike and distrust of their bodies, feeling that their bodies had somehow let them down. These fears can in turn lead to dangerous weight loss behaviors. Magnetic resonance imaging of the brain is a tool that helps highlight the underlying biological processes associated with AN. In the current study we aim to investigate how the connections in key regions of the brain are related to clinical and behavioral factors associated with AN. We found regions of two main networks were associated with body dissatisfaction and drive for thinness, which are key features of AN. The brain regions involved help explain why patients with AN have characteristics of feeling disconnected from their bodies, having difficulty labeling and regulating emotions, responding to biological needs such as hunger and fatigue, and differentiating experiences that will be rewarding. These results can help guide interventions that will be directed towards helping individuals with AN to better sense, decipher, and act on the various signals being communicated by their body.

Rigidity and Sensory Sensitivity: Independent Contributions to Selective Eating in Children, Adolescents, and Young Adults.

Objective: Selective or "picky" eating (SE) refers to rejection of a wide range of familiar and unfamiliar foods based on aversions to their sensory properties. When severe, SE can cause symptoms of avoidant/restrictive food intake disorder (ARFID), including weight loss, nutritional deficiencies, and/or psychosocial impairment. SE is highly prevalent in autism spectrum disorder (ASD) compared to both typical development and other developmental disorders. A possible explanation for the high prevalence of SE in ASD is the effect of core ASD symptoms, repetitive/restrictive behaviors (e.g., rigidity), and sensory sensitivity on feeding behaviors. These traits are found not only in ASD but also in other clinical groups and the general population, albeit often at subclinical levels. Identifying mechanisms of SE across various populations is critical to inform intervention approaches.Methods: In 263 unselected children ages 5-17, 534 unselected college students ages 18-22, 179 children with anxiety/obsessive spectrum disorders ages 5-17, and 185 children with ASD ages 4-17, we explored the unique contributions of sensory (i.e., oral texture and olfactory) sensitivities and rigidity as predictors of self/parent-reported SE.Results: In each sample, rigidity and oral texture sensitivity, controlling for olfactory sensitivity, age, and gender, emerged as significant, independent predictors of SE.Conclusions: This is the first study to highlight the importance of cognitive/behavioral rigidity to SE, and one of the first to illustrate the domain-specificity of the relationship between sensory sensitivity and SE.

Parent strategies for expanding food variety: Reflections of 19,239 adults with symptoms of Avoidant/Restrictive Food Intake Disorder.

OBJECTIVE: To characterize helpful parent feeding strategies using reflections on childhood eating experiences of adults with symptoms of Avoidant/Restrictive Food Intake Disorder (ARFID). METHOD: We explored a unique text-based dataset gathered from a population of N = 19,239 self-identified adult "picky eaters." The sample included adults with symptoms of ARFID as evidenced by marked interference in psychosocial functioning, weight loss/sustained low weight, and/or nutritional deficiency (likely ARFID), and non-ARFID participants. We leveraged state-of-the-art natural language processing (NLP) methods to classify feeding strategies that were perceived as helpful or not helpful. The best classifiers that distinguished helpful approaches were further analyzed using qualitative coding according to a grounded theory approach. RESULTS: NLP reliably and accurately classified the perceived helpfulness of caregivers' feeding strategies (82%) and provided information about features of helpful parent strategies using recollections of adults with varying degrees of food avoidance. Strategies perceived as forceful were regarded as not helpful. Positive and encouraging strategies were perceived as helpful in improving attitudes toward food and minimizing social discomfort around eating. Although food variety improved, adults still struggled with a degree of avoidance/restriction. DISCUSSION: Adults perceived that positive parent feeding strategies were helpful even though they continued to experience some degree of food avoidance. Creating a positive emotional context surrounding food and eating with others may help to eliminate psychosocial impairment and increase food approach in those with severe food avoidance. Nevertheless, additional tools to optimize parent strategies and improve individuals' capacity to incorporate avoided foods and cope with challenging eating situations are needed.

A mixed-methods approach to conceptualizing friendships in anorexia nervosa.

BACKGROUND: Individuals with anorexia nervosa have reported feelings of loneliness, social anhedonia, and interpersonal difficulties. This study sought to clarify the nature of interpersonal relationships in adults with anorexia, which may help improve existing interventions while also facilitating the attainment of something that might compete with the drive for thinness: friendships. METHODS: The present study used a mixed-methods approach to investigate friendship experiences in three groups: anorexia (n = 27), participants with a history of anorexia who are weight restored (n = 20), and healthy controls (n = 24). Thematic analysis was used to isolate the most prevalent themes that emerged from an open-ended interview of experiencing friendships in a subset of participants. Three self-report questionnaires investigating friendship valuation and attachment styles were also administered. RESULTS: 11 unique themes emerged in the data: social comparison, reciprocity, trust, fear of negative evaluation, perceived skills deficit, logistical barriers, reliability, identity issue, low interest, similarity, and conflict avoidance. Only 17% of those with anorexia reported experiencing friendships as positive, relative to 82% of healthy controls and 52% of weight restored participants. Lastly, on self-report measures, participants with anorexia reported greater reliance on themselves versus others, greater use of care-seeking behaviors, and more fear/anger at the thought of losing an attachment figure (p < .05 in all cases). CONCLUSION: Results suggest that individuals with anorexia have particular challenges which interfere with the formation and maintenance of friendships, such as viewing friendships negatively and struggling with social comparisons in friendships. Assessing and addressing barriers to intimacy may motivate those with anorexia to relinquish dangerous symptoms that maintain the illness.

Children's Beliefs about Pain: An Exploratory Analysis.

Functional abdominal pain (FAP) is one of the most common childhood medical complaints, associated with significant distress and impairment. Little is known about how children understand their pain. Do they attribute it to personal weakness? Do they perceive pain as having global impact, affecting a variety of activities? How do they cope with pain? We explored the pain beliefs of 5- to 9-year-old children with FAP using a novel Teddy Bear Interview task in which children answered questions about a Teddy bear's pain. Responses were analyzed quantitatively and qualitatively. Results indicate that the majority of young children with FAP are optimistic about pain outcomes. Children generated many types of coping strategies for Teddy's pain and adjusted their calibration of Teddy's pain tolerance dependent on the activity being performed. Early warning signs also emerged: a subset of children were pessimistic about Teddy's pain, and several children identified coping strategies that, while developmentally appropriate, could lead to excessive help seeking if not intervened upon (e.g., physician consultation and shot). The Teddy Bear Interview allows children to externalize their pain, making it a useful tool to access cognitive pain constructs in younger children. Thus, these findings highlight the importance of early intervention for childhood FAP.

The diagnosis of avoidant restrictive food intake disorder in the presence of gastrointestinal disorders: Opportunities to define shared mechanisms of symptom expression.

OBJECTIVE: Individuals with a gastrointestinal (GI) disorder often alter their diet to manage GI symptoms, adding complexity to understanding the diverse motivations contributing to food avoidance/restriction. When a GI disorder is present, the DSM-5 states that Avoidant/Restrictive Food Intake Disorder (ARFID) can be diagnosed only when eating disturbance exceeds that expected. There is limited guidance to make this determination. This study attempts to address this gap by characterizing the presentation of ARFID in adults with and without a self-reported GI disorder. METHOD: Participants were 2,610 adults ages 18-44 who self-identified as "picky eaters." Participants reported on motivations for food avoidance, affective experiences towards food, and perceived impairment. Responses were compared across four groups: GI issues and likely ARFID (L-ARFID/GI), L-ARFID-only, GI-only, and No-ARFID/No-GI. RESULTS: Groups with a GI disorder (L-ARFID/GI, GI-only) reported more fear of aversive consequences of eating than those without a GI disorder, while groups with L-ARFID (L-ARFID, L-ARFID/GI) evidenced significantly greater sensory aversion to food and indifference to food or eating, negative emotional reactions to food and overall disgust sensitivity, and eating related impairment. DISCUSSION: Consideration of the interplay of a GI disorder with ARFID can add precision to case conceptualization. Food avoidance may be attempts to manage fears of aversive consequences that are augmented by a history of GI symptoms, while sensory aversions and negative emotional reactions towards foods may be more elevated in ARFID. These findings emphasize the need to consider an ARFID diagnosis in patients with GI disorders to optimize care.

Do children with recurrent abdominal pain grow up to become adolescents who control their weight by fasting? Results from a UK population-based cohort.

OBJECTIVE: Gastrointestinal (GI) problems are common in eating disorders, but it is unclear whether these problems predate the onset of disordered eating. Recurrent abdominal pain (RAP) is the most prevalent GI problem of childhood, and this study aimed to explore longitudinal associations between persistent RAP (at ages 7 and 9) and fasting for weight control at 16. METHOD: The Avon Longitudinal Study of Parents and Children (ALSPAC) is a UK population cohort of children. Childhood RAP was reported by mothers and defined as RAP 5+ (5 pain episodes in the past year) in our primary analysis, and RAP 3+ (3 pain episodes) in our sensitivity analysis. Fasting for weight control was reported by adolescents at 16. We used logistic regression models to examine associations, with adjustments for potential confounders. RESULTS: After adjustments, we found no association between childhood RAP 5+ and adolescent fasting for weight control at 16 (OR 1.30 (95% Confidence Intervals [CI] 0.87, 1.94) p = .197). However, we did find an association between RAP 3+ and later fasting, in the fully adjusted model (OR 1.50 [95% CI 1.16, 1.94] p = .002), and after excluding those with pre-existing anxiety (OR 1.52 [95% CI 1.17, 1.97] p = .002). DISCUSSION: Our findings suggest a possible independent contribution of RAP to later risk of fasting for weight control, and RAP should be enquired about in the assessment of eating disorders. However, frequency of childhood abdominal pain (as captured by ALSPAC) may be less important to long-term outcomes than functional impairment.

Longitudinal associations of trauma exposure with disordered eating: Lessons from the Great Smoky Mountains Study.

Disordered eating is prevalent among trauma survivors, yet little is known about mechanisms underlying this relation. We explored cross-sectional and longitudinal associations of trauma exposure and posttraumatic stress disorder symptoms (PTSD) with disordered eating among 1,420 community-based youth participating in the Great Smoky Mountain Study. Participants were interviewed about trauma exposure, PTSD symptoms, and disordered eating at regular intervals throughout childhood, adolescence, and early adulthood. Our findings confirmed associations of all forms of trauma exposure (violent, sexual, and other) with disordered eating symptoms in childhood and adulthood, although the pattern of results varied by disordered eating symptom and trauma exposure type. Only non-sexual, non-violent trauma exposure in childhood had significant associations with any disordered eating symptoms in adulthood. Within childhood, trauma exposures but not PTSD symptoms showed significant longitudinal associations with bulimia nervosa symptoms and sustained appetite changes and preoccupation with eating. In adulthood, PTSD symptoms but not trauma exposures showed significant longitudinal associations only with bulimia nervosa symptoms. The association of specific PTSD clusters on bulimia nervosa symptoms was significant for reexperiencing, whereas hyperarousal symptoms trended toward significance. The impact of trauma exposures on disordered eating may vary by developmental period.

Weight-Related Behaviors of Children with Obesity during the COVID-19 Pandemic.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, children and families have had to adapt their daily lives. The purpose of this study was to describe changes in the weight-related behaviors of children with obesity after the onset of the COVID-19 pandemic. Methods: Semistructured interviews (n = 51) were conducted from April to June 2020 with parents of children with obesity. Families were participants in a randomized trial testing a clinic-community pediatric obesity treatment model. During interviews, families described their experience during the COVID-19 pandemic, with a particular emphasis on children's diet, physical activity, sleep, and screen time behaviors. Rapid qualitative analysis methods were used to identify themes around changes in children's weight-related behaviors. Results: The mean child age was 9.7 (±2.8) years and the majority of children were Black (46%) or Hispanic (39%) and from low-income families (62%). Most parent participants were mothers (88%). There were differences in the perceived physical activity level of children, with some parents attributing increases in activity or maintenance of activity level to increased outdoor time, whereas others reported a decline due to lack of outdoor time, school, and structured activities. Key dietary changes included increased snacking and more meals prepared and consumed at home. There was a shift in sleep schedules with children going to bed and waking up later and an increase in leisure-based screen time. Parents played a role in promoting activity and managing children's screen time. Conclusions: The COVID-19 pandemic has created unique lifestyle challenges and opportunities for lifestyle modification. Clinical Trials ID: NCT03339440.

Increased emotional eating behaviors in children with autism: Sex differences and links with dietary variety.

LAY ABSTRACT: Although "picky" eating is well documented in autism spectrum disorder, emotional eating has rarely been investigated. This study examined emotional over- and under-eating based on parent ratings of these behaviors in 4- to 17-year-old children with autism spectrum disorder (n = 190) as compared to same-age typically developing children (n = 119). Children with autism spectrum disorder were rated as exhibiting both more emotional over-eating and more emotional under-eating behaviors than their typically developing peers. Furthermore, while sex differences in these emotional eating behaviors were not observed in the typically developing children, girls with autism spectrum disorder were rated as experiencing more emotional over-eating behaviors than boys with autism spectrum disorder. Finally, among all children with autism spectrum disorder, emotional over-eating was linked with increased consumption of sweet foods and decreased consumption of vegetables. These findings have implications for better understanding eating habits in children with autism spectrum disorder and suggest that emotional eating behaviors might have both immediate and downstream health impacts.

Do interoceptive accuracy and interoceptive sensibility predict emotion regulation?

INTRODUCTION: Interoception refers to awareness, interpretation, and integration of sensations in the body. While interoceptive accuracy has long been regarded as a core component of emotional experience, less is known about the relationship of interoceptive accuracy and related facets of interoception to emotion regulation deficits. This study explores how interoceptive accuracy and interoceptive sensibility relate to emotion regulation in a non-clinical sample. METHODS: Undergraduate participants completed a heartbeat perception task and the Multidimensional Assessment of Interoceptive Awareness (Noticing and Body Listening sub-scales), and rated their confidence in performance on the heartbeat perception task. Participants also completed self-report measures of emotional awareness and regulation (Profile of Emotional Competence, intrapersonal emotion identification and emotion regulation sub-scales), and rated their use of different coping strategies (Brief COPE). RESULTS: Noticing predicted emotion identification, emotion regulation, and the use of adaptive but not maladaptive coping strategies. Heartbeat perception accuracy did not significantly contribute to the prediction of any outcome variables. DISCUSSION: Future work is needed to extend these findings to clinical populations. The results from this study support the use of interoceptive training interventions to promote emotional wellbeing.

The clash of culture and cuisine: A qualitative exploration of cultural tensions and attitudes toward food and body in Chinese young adult women.

OBJECTIVE: Accumulating evidence suggests that the prevalence of eating disorders among Chinese women is a public health concern. Prior studies have drawn linkages between conflicting cultural values, identity confusion, and eating disorder symptomatology, which may be relevant for understanding the rise of eating disorders amidst China's rapid economic and sociocultural transformation. Here, we explore how women's experiences with traditional eating norms and modernizing norms of femininity may shape their food and body attitudes. METHOD: Chinese young adult women (N = 34; aged 18-22 years) participated in semi-structured interviews focusing on experiences with norms surrounding eating and ideal feminine appearance, perceived conflict between these norms, and their responses to perceived conflict. Interviews were conducted via email (n = 27) or via Skype (n = 7). Participants were not asked about past or present diagnoses of eating disorders. Analysis of responses was guided by the principles of thematic analysis. RESULTS: Women reported encounters with cultural eating norms and feminine appearance norms, and described factors that motivated continued or discontinued adherence to these norms. Women reported strategies of conflict resolution, which resulted in different emotional and behavioral outcomes including eating disorder symptoms. DISCUSSION: Women's experiences with norms surrounding eating and appearance indicate the centrality of these encounters in the formation of individual and interpersonal values. Our findings suggest the importance for clinicians to assist clients in exploring the meanings behind internalized attitudes toward food and body, and to help clients balance interpersonal and individual needs.
