Eating behaviors最新文献

Objective

Parents' negative body talk about children (negative weight/shape comments) and internalized weight bias (application of negative weight-based stereotypes to oneself) are associated with children's maladaptive eating behaviors, but mechanisms are poorly understood. Conceptually, parental behaviors and attitudes may translate to implicit and explicit concerns about their child's weight and influence parents' feeding practices. These associations are underexplored in the literature.

Method

242 parents (59.4% mothers) completed a one-time assessment that included measures of internalized weight bias, negative body talk, and feeding practices. Parents also completed assessments about one of their children, of any weight status (age range 5–15 years; 40% daughters).

Results

Parents' internalized weight bias was positively associated with concern about their child's weight and restriction of their child's diet. Parents' negative body talk towards their child was positively associated with concern about their child's weight and shape, restriction of their child's diet, and monitoring of their child's diet. Relative to internalized weight-bias, negative body talk had a stronger correlation with parents' concern about child weight and monitoring of child's diet. Correlations did not vary by child gender or weight category.

Discussion

Parents' internalized weight bias and negative body talk about their child were associated with their feeding practices across child gender and weight categories, with correlations in the small to medium range. Thus, children of all genders and weights may be vulnerable to enacted weight bias. Future studies should examine whether addressing parents' internalized weight bias and communication in family-focused interventions improves feeding practices and child well-being.

Disordered eating and body image concerns are particularly prevalent among women who are engaged to be married (i.e., brides-to-be), and this population may be subject to increased social and cultural pressure to achieve specific appearance ideals. The tripartite influence model purports that appearance pressures from four sources (peers, family, romantic partners, and media) influence body image and disordered eating outcomes through thin ideal internalization and appearance comparison. The present cross-sectional study sought to examine the relationships between tripartite theory constructs, body image, and disordered eating among 329 brides-to-be using path analysis with robust estimation. In the final model, media influence was the only tripartite predictor associated with both thin ideal internalization and appearance comparison. Further, thin ideal internalization and appearance comparison were associated with disordered eating directly as well as indirectly through body dissatisfaction. Altogether, the influence variables explained 39 % of the variance in disordered eating. While appearance pressures from media, peers, and partners were indirectly associated with disordered eating through one or more hypothesized indirect pathways, appearance pressure from family was not, indicating this relationship may be uniquely impacted by other factors not captured in tripartite models. Results suggest that family and media influence are most strongly associated with disordered eating in this group and have the capacity to inform future research as well as intervention development and dissemination.

Background

Eating too much sugar is associated with many negative health effects. Two brief online interventions were carried out to investigate whether information about the negative consequences of eating high-sugar food vs. positive consequences of eating low-sugar food can change reported appetite, mood, and visual food cue attention.

Method

For Study I, participants (n = 201) were allocated to one of three groups: Two groups were asked to list either the negative consequences of high-sugar consumption (negative focus) or the positive consequences of low-sugar consumption (positive focus). The third group carried out a control task (writing a shopping list). For Study II, 200 participants took part in a quiz with questions focusing on either positive, negative, or neutral consequences of high vs. low sugar consumption. Participants evaluated their appetite and mood before and after all interventions (list, quiz) and additionally completed a visual probe task with images depicting high vs. low-sugar food.

Results

In Study I, the positive focus increased appetite for low-sugar food. The negative focus reduced participants' positive mood but did not change reported appetite. In Study II, all quiz conditions decreased appetite for high-sugar foods but did not affect mood. None of the interventions influenced visual attention to the food images.

Conclusion

Focusing on negative consequences of a high-sugar diet is less pleasant and is less effective in changing people's appetite than considering the positive aspects of a low-sugar diet. Thus, future interventions should instead spotlight the positive outcomes of a healthy diet.

Parenting style is associated with children's eating behavior, yet less is known about how parenting style and coparenting are both related to children's eating behavior (food approach behavior and palatable food intake) and weight-related outcomes (concern about child weight and perceived child weight). The aims of the current research were 1) to determine family profiles based on parenting style and coparenting, 2) to examine whether the family profiles were associated with parent (sex, BMI, age) and child (sex, age) characteristics, and 3) to examine whether the family profiles differed in children's outcomes. Parents (n = 185; M_age = 36.38 years, SD = 7.69) of 3- to 8-year-old children completed an online survey. Latent profile analysis revealed three family profiles: 1) Responsive and Cooperative, 2) Minimally Structured, and 3) Demanding and Competitive. The family profiles were not related to any parent or child characteristics. The Responsive and Cooperative family profile was associated with the lowest food approach behavior, palatable food intake, and weight-related outcomes, followed by the Minimally Structured family profile, and finally the Demanding and Competitive family profile with the highest scores. These findings suggest family dynamics play an important role in children's propensity to engage in food approach behavior and palatable food intake.

Recent research suggests high rates of posttraumatic stress disorder (PTSD) and eating disorder (ED) comorbidity in women veterans. This study aims to expand the literature by examining associations between PTSD and ED diagnoses and symptoms in this population. We assessed probable PTSD diagnosis and symptom clusters (intrusion, avoidance, arousal and reactivity, and negative alterations in cognition and mood [NACM]), as well as probable Binge Eating Disorder (BED) diagnosis and ED subscales (dietary restraint, shape/weight overvaluation, and body dissatisfaction) in a sample of women veterans (N = 371). We investigated significance at the standard p < .05, and the Bonferroni-corrected p < .005 cut-off to adjust for experiment-wise error. Overall, we found that probable PTSD was associated with provisional BED (p < .001) using logistic regression at both cut-offs. Probable PTSD was associated with all ED subscales (all p's < 0.003) using linear regression models also at both cut-offs. Provisional BED was associated with NACM at p < .05 (p = .046), though it did not meet significance at our conservative cut-off. NACM was also associated with shape/weight overvaluation (p = .02) and a global ED score (p = .01) at p < .05, but not at our conservative cut-off; arousal was associated with shape/weight overvaluation (p = .04) and the global ED score (p = .02) at p < .05, but not at our conservative cut-off. Our findings may further guide how ED-related topics can be integrated in PTSD treatment for women veterans with comorbid PTSD and ED.

Introduction

The prevalence of food addiction among patients seeking bariatric surgery is approximately 30 %. While hyper-palatable foods (HPF) have been identified as the potential ‘substance’ in food addiction and a contributor to severe obesity, consumption of HPF among individuals with food addiction, including those seeking bariatric surgery, is unknown. Thus, the aim of this study was to evaluate the consumption of HPF among individuals seeking bariatric surgery with food addiction, compared to those without food addiction.

Methods

Participants were N = 54 individuals with severe obesity seeking bariatric surgery. The Yale Food Addiction Scale was used to identify individuals with food addiction (FA) (37 % of sample). Dietary recalls were used to quantify HPF intake. Analyses were conducted to characterize average HPF intake and to determine whether there were significant differences between HPF intake among those with FA compared to those without FA, and whether HFP intake was correlated with FA symptoms.

Results

On average, 71 % of participants' daily calorie intake was from HPF. There were no significant differences in HPF items intake among individuals with and without FA (70.46 % vs 71.34; p = 0.85). A positive correlation between number of FA symptoms and the intake of HPF high in fat and sugar ([0.3]; p = 0.03) was observed.

Conclusion

In this pilot study, HPF consumption among individuals with and without FA seeking bariatric surgery was high overall, however there were no differences across groups. In addition, intake of HPF with fat and sugar was associated with the number of symptoms of food addiction. More studies with a larger sample are needed to confirm these preliminary findings.

Introduction

The use of weight-inclusive programming within a workplace wellness context remains understudied.

Methods

The present study is a pilot/feasibility study of a 3-month, virtual, weight-inclusive, intuitive eating-based workplace wellness program. Program participants (n = 114), who were all employees at a large public university in the Midwest, received weekly emails with a link to an instructional video related to intuitive eating and were encouraged to meet virtually with their health coach. Participants provided self-report data on behavioral and psychological outcomes including intuitive eating, internalized weight stigma, eating disorder symptoms, and diet quality at baseline, post-intervention (3 months from baseline), and follow-up (6 months from baseline). Changes in behavioral and psychological outcomes from baseline to post-intervention and follow-up were examined using paired t-tests, with Cohen's d effect sizes reported. Generalized linear models were used to examine whether participant characteristics and program engagement were associated with program outcomes.

Results

Increases in intuitive eating and decreases in internalized weight stigma and eating disorder symptoms were seen from baseline to post-intervention (Cohen's d = 1.02, −0.47, and −0.63, respectively) and follow-up (Cohen's d = 0.86, −0.31, and −0.60). No changes in dietary quality were seen at post-intervention, but a significant reduction in intake of added sugars, fast food, and sugar sweetened beverages were observed at follow-up (Cohen's d = −0.35, −0.23, −0.25).

Conclusions

This study provide preliminary support for the acceptability and potential impact of a weight-inclusive workplace wellness program that should be tested in a rigorous randomized trial.

It is well-established that binge-eating (BE) is linked to emotion regulation (ER) difficulties. However, research to date has focused almost exclusively on difficulties regulating negative emotions, with little attention to the relationship between positive emotion dysregulation and BE. Further, research is inconclusive regarding which specific facets of ER difficulties are most strongly associated with BE behaviour. Therefore, the current study examined whether difficulties regulating both negative as well as positive emotions explained unique variance in BE among young adults. The study also aimed to identify which particular dimensions of negative and positive ER difficulties were most strongly related to BE symptoms. Participants (N = 449) ages 18–25 completed self-report measures of difficulties regulating positive and negative emotions, BE symptoms, and psychological distress. Hierarchical regression analyses showed that BE was related to difficulties regulating both positive emotions and negative emotions, after controlling for psychological distress and BMI. Lack of emotional clarity and lack of access to ER strategies when faced with strong negative emotions were the facets of negative ER difficulties most strongly associated with BE. Impulsivity when experiencing strong positive emotions was the facet of positive ER difficulties most strongly associated with BE. These findings support the ER model of BE and suggest that difficulties regulating both positive and negative emotions contribute to BE among young adults.

Structure-related feeding practices may promote intuitive child eating behaviors and foster responsiveness to internal cues of hunger and satiety. Caregivers' ability to engage in structure-related feeding practices likely depends on a complex ecology of factors, including household- and child-characteristics. This study examined associations between household chaos and structure-related feeding practices, and the moderating effect of child temperament. Data were from 275 caregiver-toddler dyads from central Ohio. Child temperament was reported by caregivers when children were 18 months of age, whereas household chaos and structure-related feeding practices were reported by caregivers when children were 36 months of age. Multivariable linear regression models were constructed to assess the relationship between chaos and structure-related feeding practices. Interaction terms between household chaos and three dimensions of child temperament were tested to determine whether temperament moderated the relationship between chaos and structure-related feeding practices. Household chaos was not independently associated with structure-related feeding practices, but higher levels of child effortful control were associated with greater mealtime structure. There was a statistically significant interaction between household chaos and child temperamental surgency, such that greater levels of chaos were associated with less structured mealtimes, but only when children had low-surgency. Findings suggest household chaos and child temperament inform caregiver feeding practices, but the influence of chaos may depend on more proximal factors, like child temperament. Recommendations to improve caregiver-child feeding interactions should be sensitive to characteristics of the broader family home environment.

Weight-related abuse is defined as verbal or physical maltreatment specific to one's weight. The Weight-Related Abuse Questionnaire (WRAQ) is an instrument specifically designed to measure weight-related abuse. The main goal of this research was to study the factor structure and measurement invariance of the Spanish version of the WRAQ in a non-clinical and a clinical sample. The clinical sample included 150 participants with obesity (60 % women) from the (masked for blind review) Hospital. The non-clinical sample included 301 students (79 % women) from the (masked for blind review) University. Scales to measure weight self-stigma and fear of gaining weight were used to analyze the convergent validity of the WRAQ. A confirmatory factor analysis showed that a two-factor model (verbal and physical abuse) was an acceptable fit for the data in both the clinical and non-clinical samples. Multigroup Confirmatory Factor Analysis revealed scalar measurement invariance by sample and gender. Cronbach's alpha coefficients and composite reliability for both samples were found to be good, with values ranging from 0.83 to 0.96. Fear of gaining weight was correlated to verbal (r = 0.36, p < .01) and physical (r = 0.12, p < .05) abuse, and weight self-stigma was also related to physical (r = 0.21, p < .01) and verbal (r = 0.41, p < .01) abuse. These results suggest that the WRAQ can be used in clinical and non-clinical samples to assess verbal and physical abuse in both men and women.
