Classifying and characterizing Chinese young adults reporting picky eating: A latent profile analysis

Peer Teasing and Restrained Eating among Chinese College Students: The Chain Mediating Role of Negative Coping Styles and Negative Physical Self

This study aimed to determine whether negative coping styles and negative physical self sequentially mediate the relationship between peer teasing and restrained eating among Chinese university students. In total, 1127 participants (66.9% women, average age = 18.43 years; age range, 14-26 years) completed the Perception of Teasing Scale, Coping Style Questionnaire, Negative Physical Self Scale, and the Chinese version of the Restraint Scale. The mediational analysis showed that, after controlling for age, sex, and body mass index (BMI), peer teasing was related to restrained eating behaviors through (a) the mediating effect of negative coping styles, (b) the mediating effect of negative physical self, and (c) the chain-mediating effect of negative coping styles and negative physical self. This study showed for the first time that negative coping styles and negative physical self may chain mediate the association between peer teasing and restrained eating. It also provides suggestions for clinical practices as to strategies for controlling restrained eating.

Higher meal disengagement and meal presentation are uniquely related to psychological distress and lower quality of life in undergraduate students

Objective: Picky eating, which occurs in emerging adulthood and is associated with psychological distress and quality of life, has historically been conceptualized as unidimensional despite research suggesting it is a multifaceted construct. Participants: An undergraduate sample (N = 509; Mage = 19.96). Methods: A cross-sectional survey assessed picky eating facets (food variety, meal disengagement, meal presentation, and taste aversion), disordered eating, anxiety, depression, stress, obsessive compulsive disorder (OCD), and social phobia symptoms, and quality of life. Results: Meal disengagement was uniquely related to higher anxiety, depression, stress, and social phobia symptoms and lower quality of life, whereas meal presentation was uniquely related to higher anxiety, stress, and OCD symptoms, beyond covariates and disordered eating. Food variety and taste aversion were not uniquely related to outcomes. Conclusions: Considering picky eating multidimensionally may yield important insights beyond the broader construct in terms of its relationship with psychological well-being in undergraduates.

Picky eating is associated with lower life satisfaction and elevated psychological distress and psychosocial impairment in Chinese pregnant women

OBJECTIVE

This study assessed picky eating in pregnant women by exploring whether picky eating is associated with pregnant women's well-being, including life satisfaction, psychological distress, and psychosocial impairment.

METHOD

Data collected were from 345 Chinese pregnant women (M age = 29.95 years, SD = 5.58). Pearson correlation analyses were conducted to examine zero-order correlations between picky eating and well-being variables (i.e., life satisfaction, psychological distress, and psychosocial impairment). Hierarchical multiple regressions were conducted to examine the unique associations of picky eating with well-being variables, adjusting for demographic and pregnancy-related characteristics and thinness-oriented disordered eating.

RESULTS

Picky eating was significantly and negatively correlated with life satisfaction (r = -.24, p < .001) and positively correlated with psychological distress (r = .37, p < .001) and psychosocial impairment (r = .50, p < .001). When adjusting for covariates and thinness-oriented disordered eating, picky eating was still significantly associated with lower life satisfaction, higher psychological distress, and higher psychosocial impairment.

DISCUSSION

The findings suggest that picky eating may be a significant correlate of pregnant women's poorer well-being. Future research with longitudinal designs is warranted to further examine the temporal associations between picky eating and pregnant women's well-being.

PUBLIC SIGNIFICANCE

Picky eating behaviors are poorly understood in pregnant women. Our results revealed that higher picky eating behaviors were associated with lower life satisfaction and higher psychological distress and psychosocial impairment in Chinese pregnant women. Researchers and clinicians may consider picky eating in the assessment and treatment of mental health and disordered eating in pregnant women.

Food insecurity and disordered eating behaviors in children and adolescents: A systematic review

This study is the first systematic review to investigate the relationship between food insecurity (FI) and disordered eating behaviors exclusively in children and adolescents. Database searches were conducted in PUBMED, Embase, PsycINFO, ProQuest, and Gale OneFile: Informe Académico using English and Spanish search terms. Studies were included if they were published before August 2022, included youth aged 18 years and below, included either parent- or child-report of food security status, included either parent- or child-report of child disordered eating behaviors, and examined the relationship between food security status and child disordered eating behaviors. Following independent title/abstract and full-text screening, 20 studies were included in the review. There were 13 cross-sectional studies, five longitudinal studies, and two qualitative studies, from the United States (19 studies), and Bangladesh (1 study). Sample sizes ranged from 33 to 6077. Findings generally indicated a relationship between FI and behaviors such as binge eating, loss-of-control eating, eating in the absence of hunger, unhealthy weight control behaviors, and picky eating in children and adolescents, though this association varied depending on the type of disordered eating behavior assessed and FI severity. Results highlight the importance of screening for disordered eating behaviors among youth with FI towards eating disorder prevention and intervention. However, given the limited number of primary research articles examining this relationship in youth, further hypothesis-driven research is needed. In addition, more global representation and additional longitudinal studies are needed to further examine the generalizability and temporality of FI and disordered eating in children and adolescents.

Negative emotional eating patterns among American university students: A replication study

Emotional eating (EE) has been consistently associated with obesity, weight gain, and certain eating disorders (EDs). Given the cultural influence on food consumption and eating styles, comparison of EE patterns of individuals in culturally distinct nations (e.g., USA and China) could yield interesting differences in findings. However, given the increasing convergence in eating practices between the above-mentioned nations (e.g., higher reliance on outdoor eating at restaurants among Chinese adolescents), EE patterns might share significant similarities. The present study examined EE patterns of American college students and is a replication of the study done by He, Chen, Wu, Niu, and Fan (2020) on Chinese college students. Responses of 533 participants (60.4% women, 70.1% White, aged 18-52 (mean age = 18.75, SD = 1.35), mean self-reported body mass index = 24.22 kg/m² and SD = 4.77) on the Adult Eating Behavior Questionnaire (Emotional overeating and emotional undereating subscales) were examined using Latent Class Analysis to identify specific patterns of EE. Participants also completed questionnaire measures of disordered eating and associated psychosocial impairment, depression, stress, and anxiety symptoms, and a measure of psychological flexibility. A solution with four classes emerged, i.e., emotional over- and undereating (18.3%), emotional overeating (18.2%), emotional undereating (27.8%), and non-emotional eating (35.7%). Current findings replicated and extended findings from He, Chen, et al. (2020) in that the emotional over- and undereating class exhibited the highest risks for depression, anxiety, stress, and psychosocial impairment due to disordered eating symptoms as well as lower psychological flexibility. Individuals who have difficulty with awareness and acceptance of their emotions appear to engage in the most problematic form of EE and could benefit from Dialectical behavior therapy and Acceptance and commitment therapy skills training.

How multiple threats to safety affects quality of life for picky eating adults: A new explanatory model

Picky eating describes a pattern of eating characterised by a narrow dietary range with rejection of both novel and familiar foods. Research has suggested that picky eating in adulthood is associated with several negative psychosocial outcomes including impaired quality of life. This research aimed to build and test a model explaining the relationship between picky eating and quality of life. 230 participants were recruited via online support forums for picky eating, and an undergraduate research participation scheme. Participants completed self-report measures of picky eating, sensory sensitivity, disgust, anxiety, fear of negative evaluation and eating related quality of life. Regression analysis indicated that picky eating, disgust sensitivity, anxiety, and fear of negative evaluation were all associated with impaired eating-related quality of life. A theoretical model was then devised which aimed to explain the interactions between these factors, and Path Analysis indicated that this model was a good fit for the data. This Safety in Picky Eating and Quality of life (SPEQ) model suggests that threat perception and the drive for safety underlies the relationship between picky eating and impaired quality of life. The SPEQ model provides a preliminary basis for understanding how picky eating impacts quality of life in adulthood.

Satisfaction with Food: Profiles of Two-Parent Families with Adolescent Children

The objectives of this study were to distinguish family profiles based on the level of satisfaction with food-related life (SWFoL) of mothers, fathers, and adolescents, and to characterize the profiles based on the three family members' diet quality and nutritional status, family's eating habits, parental feeding practices, parent's nutritional knowledge, and sociodemographic characteristics. Questionnaires were applied to a sample of 300 two-parent families with adolescent children, aged between 10 and 17 years, in Temuco, Chile. The questionnaires used were: satisfaction with food-related life (SWFoL); adapted healthy eating index (AHEI); family eating habits questionnaire (FEHQ); and the nutritional knowledge subscale. They also answered questions about eating habits and provided data to determine BMI and sociodemographic characteristics. Four different profiles were identified with respect to SWFoL: "Families satisfied with their food" (50.6%); "Fathers and mothers moderately satisfied with their food, children satisfied" (23.2%); "Families extremely satisfied with their food" (16.6%); and "Fathers and mothers satisfied with their food, children extremely dissatisfied" (9.7%). The profiles demonstrated heterogeneity in SWFoL. Higher levels of SWFoL (mothers, fathers and adolescents) were associated with healthier eating habits. These results contribute to new studies that enable understanding of how families' healthy eating habits are part of improving quality of life.

Food approach and avoidance appetitive traits in university students: A latent profile analysis

Eating behaviors are influenced by many factors including appetitive traits. Few studies have utilized latent profile analysis (LPA) to examine food approach and food avoidance appetitive traits. This study utilized LPA to define cluster profile groups based on appetitive traits in undergraduate and graduate/professional students at a large University in the southwest United States. Students completed a cross-sectional online survey in fall 2020 assessing demographic information, appetitive traits via the Adult Eating Behavior Questionnaire (AEBQ), and anxiety via the Generalized Anxiety Disorder Scale (GAD-7; higher scores indicate more severe anxiety symptoms). Appetitive traits were combined into eight scales (four food approach and four food avoidance traits). Latent profile analyses were conducted to identify homogenous subgroups of participants based on AEBQ scale scores. The final sample included 1243 students (mean age = 26.5 years, 73% female, 59% White, 57% undergraduates). LPA revealed four cluster profile groups: Cluster 1 (moderate eaters: lower than mean scores for food approach and avoidance traits), Cluster 2 (food seekers and avoiders: higher than mean scores for food approach and avoidance traits), Cluster 3 (food seekers: higher than mean scores for food approach traits), and Cluster 4 (food avoiders: higher than mean scores for food avoidance traits). Distribution of age, gender, race/ethnicity, and student status differed significantly between clusters. GAD-7 score was highest in Cluster 2 (food seekers and avoiders) and lowest in Cluster 1 (moderate eaters). Among the four LPA-defined cluster profile groups, students who endorsed both food approach and avoidance traits reported more severe anxiety symptoms compared to moderate eaters, food seekers, and food avoiders. It is useful to consider clusters of appetitive traits instead of individual appetitive traits when examining associations with physical and mental health.

The imputation of structure in random patterns as a cognitive factor predicting adult picky eating behavior

We raise the hypothesis that adult picky eating behavior may be related to subjects' tendency to impute structure in random stimuli. We test said hypothesis in an empirical study which operationalizes subjects' objective abilities and subjective decision criteria in discriminating between correlated and independent signals in terms of the classic Signal Detection Theory. A robust regularized Bayesian multiple regression analysis indicates that liberal subjective decision criteria which indicate a tendency to over-impute structure when trying to discriminate between random and correlated patterns are associated with elevated scores of picky eating while controlling for several other variables. The predictive power of our discriminating procedure appears comparable to that of related eating dispositions. Our results strongly suggest that cognitive factors might indeed have substantial and meaningful relationships with certain eating behaviors.

The relationship between body weight and dietary restraint is explained by body dissatisfaction and body image inflexibility among young adults in China

OBJECTIVE

Eating disorders and obesity are commonly recognized as key public health concerns worldwide. Although rates of obesity and disordered eating have traditionally been lower in China than Western countries, these rates are on the rise. As such, interest is growing in identifying mechanisms that may address these conditions. While associations between body weight and dissatisfaction are well established, burgeoning research aims to examine how these factors are related to dietary restraint and body image inflexibility. This study aimed to explore the possible mediation effect of body dissatisfaction and body image inflexibility between body weight (body mass index) and dietary restraint. Furthermore, we explored how these relationships differed across men and women.

METHODS

A sample of 1068 young adults (563 females and 505 males) in China participated in the study. Participants completed the Eating Disorder Inventory and Three-Factor Eating Questionnaire as well as the Body Image-Acceptance and Action Questionnaire.

RESULTS

Results showed that: (1) body dissatisfaction and body image inflexibility fully mediated the relationship between body mass index and dietary restraint; (2) this model fit both genders, although differences were found in the regression coefficients between the mediation model for men and women.

CONCLUSION

These findings support body image dissatisfaction and inflexibility as mediators of the relationship between body weight and dietary restraint, highlighting these as potential mechanisms for treatment.

LEVEL OF EVIDENCE

Level III, case-control analytic study.

Validation of the Chinese Version of the Body Image Acceptance and Action Questionnaire and the Mediating Role of Body Image Flexibility in the Relationship Between Body Dissatisfaction and Psychological Distress

The psychometric properties of the Chinese version of the Body Image Acceptance and Action Questionnaire (C-BI-AAQ) and its short form (C-BI-AAQ-5) were examined with a sample of Chinese undergraduates (n =1,068, 52.6% female). The factor structure, measurement reliability, measurement invariance across gender, and latent gender mean difference of the two scales were explored. Confirmatory factor analysis was used to examine the factor structure of the C-BI-AAQ and the C-BI-AAQ-5. The original one-factor structure was replicated for both the C-BI-AAQ and the C-BI-AAQ-5. Both the C-BI-AAQ and C-BI-AAQ-5 showed good internal consistency, test-retest reliability, and convergent and discriminant validity (e.g., relationship patterns in the expected directions with theoretically similar psychological flexibility, and with theoretically dissimilar body dissatisfaction, and psychological distress). The C-BI-AAQ-5 was shown to be equivalent to the C-BI-AAQ. Furthermore, strict measurement invariance across gender was confirmed for both the C-BI-AAQ and C-BI-AAQ-5, and latent mean difference tests showed that men had higher levels of body image flexibility than women. Thus, both the C-BI-AAQ and C-BI-AAQ-5 appear to be psychometrically sound instruments for use in the Chinese young adult population. In addition, body image flexibility measured by both the C-BI-AAQ and the C-BI-AAQ-5 fully mediated the relationship between body dissatisfaction and psychological distress.

Estimated prevalence of eating disorders in Singapore

OBJECTIVE

There is a lack of research on the prevalence of eating disorders (EDs) in Singapore. The aims of our study were to (a) estimate the prevalence of EDs, risk status, and help-seeking behaviors among adults in Singapore, (b) examine gender differences between ED status groups, and (c) characterize clinical profiles of ED status groups.

METHOD

We administered a cross-sectional survey that included a validated EDs screening tool to adults in Singapore.

RESULTS

A total of 797 Singaporean adults ages 21-77 years completed the ED screen. The majority of participants screened positive for a current DSM-5 clinical ED (6.2%), other specified feeding or ED (37.0%) or at high risk of developing an ED (19.5%). Only 1.6% of those who screened positive for an ED reported currently being in treatment. The ratio of males to females who screened positive for an ED was nearly 1:1. The clinical profiles of ED groups were consistent with the clinical presentations found in Western nations.

DISCUSSION

This is the first study in Singapore to estimate the prevalence of EDs in a large sample of adults. Results highlight the urgent need for more ED research and expansion of prevention and treatment programs to address the high prevalence of ED psychopathology in Singapore.

The interaction of negative psychological well-being and picky eating in relation to disordered eating in undergraduate students

The extant literature on picky eating focuses on children, leaving adults understudied. A sparse and mixed evidence base suggests relationships exist between picky eating and disordered eating in adults. The present study furthered this research by examining shared negative psychological correlates as moderators that may strengthen relationships between picky eating and disordered eating in undergraduate students. Participants (N = 509; 76.3% female) completed a cross-sectional survey assessing picky eating (Adult Picky Eating Questionnaire), disordered eating (Binge Eating Scale and Eating Disorder Examination-Questionnaire), and negative psychological correlates including anxiety, depression, and stress (Depression, Anxiety and Stress Scale - 21 Items), inflexible eating (Inflexible Eating Questionnaire), obsessive compulsive disorder (Short Obsessive Compulsive Disorder Screener), and social eating anxiety (adapted Social Phobia Scale) symptoms. Positive relationships were observed between picky eating and binge eating, dietary restraint, eating concerns, overall eating pathology, and all negative psychological correlates. Moderation analyses examined if negative psychological correlates strengthened relationships between picky eating and disordered eating. Higher inflexible eating and anxiety and stress symptoms interacted with higher picky eating in relation to disordered eating, specifically eating concerns. Interactions between picky eating and negative psychological correlates did not explain variance in binge eating, dietary restraint, and overall eating pathology. Findings complement research demonstrating overlap between picky eating and disordered eating and highlight specific negative psychological correlates that may strengthen relationships between picky eating and disordered eating. Researchers and clinicians interested in concurrent picky eating and disordered eating should consider these negative psychological correlates given their potential to worsen disordered eating.

Appetitive Traits in a Population-Based Study of Polish Adolescents within the PLACE-19 Study: Validation of the Adult Eating Behavior Questionnaire

Appetitive traits of food approach or food avoidance are commonly measured using the Adult Eating Behavior Questionnaire (AEBQ). However, there is no Polish version of the AEBQ validated for adolescents, and to the best of our knowledge, no study completed with the Polish version of the AEBQ has been published thus far. The present study aimed to validate the AEBQ in a population-based sample of Polish secondary school students and to assess differences in appetitive traits between boys and girls within the Polish Adolescents' COVID-19 Experience (PLACE-19) Study. The PLACE-19 Study was conducted in a group of 2448 adolescents recruited in May 2020 through the random quota sampling of secondary schools. The AEBQ was used to assess food approach subscales (Food Responsiveness, Emotional Over-Eating, and Enjoyment of Food) and food avoidance subscales (Satiety Responsiveness, Emotional Under-Eating, Food Fussiness, and Slowness in Eating). To validate the questionnaire, the standardized factor loadings within confirmatory factor analysis (CFA) with weighted least squares (WLS) were analyzed, and invariance was verified. The CFA presented good model fit, with χ² = 4826.105 (degrees of freedom (df) = 384), root mean square error of approximation (RMSEA) = 0.069 (90% confidence interval (CI): 0.067, 0.070), comparative fit index (CFI) = 0.90, and standardized root mean square residual (SRMR) = 0.08. The results revealed that, compared to the configural invariance model, the metric invariance model did not result in significantly decreased model fit, with ΔCFI = -0.002 and ΔRMSEA = -0.001, which were lower than the recommended cutoffs of 0.010 and 0.015, respectively. The scalar invariance model also did not result in significantly decreased fit of the model over the metric invariance model, with ΔCFI = -0.005 and ΔRMSEA = 0.000. Girls reported higher levels of Food Responsiveness (p < 0.0001), Emotional Over-Eating (p < 0.0001), Satiety Responsiveness (p < 0.0001), Emotional Under-Eating (p < 0.0001), and Slowness in Eating than boys (p < 0.0001), and the total AEBQ scores of girls were also higher (p < 0.0001). Positive inter-correlations were observed between all food approach subscales, as well as between Emotional Under-Eating and all food approach subscales for girls, boys, and the total sample; positive inter-correlations were also observed between the majority of food avoidance subscales. The present study confirmed the validity of the AEBQ in the studied population, and supported the associations between appetitive traits assessed using the AEBQ; it also indicated higher scores of both food approach and food avoidance subscales in girls than in boys in a population-based sample of Polish secondary school students.

Patterns of negative emotional eating among Chinese young adults: A latent class analysis

There is ample evidence suggesting that negative emotional eating is closely related to disordered eating behaviors. However, most previous studies on the topic focused only on emotional over-eating, but neglected emotional under-eating. Moreover, previous studies also mainly used variable-oriented methods by reducing negative emotional eating to a single dimension, which limits our understanding of individual differences in negative emotional eating. In this study, we used a person-oriented approach, latent class analysis (LCA), to examine the negative emotional eating patterns and to characterize these patterns in a sample of 1,068 Chinese young adults (52.6% females, aged 17-24 years). Negative emotional eating was measured by the Emotional Over-Eating and Emotional Under-Eating subscales of the Adult Eating Behavior Questionnaire. Four patterns, namely, "non-emotional eating" (38.9%), "emotional over- and under-eating" (15.4%), "emotional over-eating" (14.7%), and "emotional under-eating" (31.0%), were identified. Sex and BMI were found to be statistically significant predictors for negative emotional eating patterns. The identified four patterns showed significant differences in eating disorder symptoms and psychological distress. Particularly, participants in emotional over- and under-eating exhibited the highest level of eating disorder symptoms and psychological distress. Overall, this study identified four distinct negative emotional eating patterns, among which, the emotional over- and under-eating was the most problematic. Future studies regarding negative emotional eating and its impact on mental health may benefit from focusing not only on individuals with emotional over-eating, but also on those showing a mixed pattern of negative emotional eating.
