Eating behaviors最新文献

Arab, Middle Eastern, and North African (A-MENA) American women are often subject to intersectional discrimination, and they have also not been traditionally recognized as a distinct racial group in disordered eating literature. No study to date has provided descriptive information on disordered and emotional eating A-MENA American women, nor has examined perceptions of widely used measurements of eating pathology in this population. The current study generated descriptive information among A-MENA women on two widely used measures of eating pathology, the Eating Disorder Examination Questionnaire (EDE-Q) and the Emotional Eating Scale (EES). Participants (N = 244) were A-MENA adult women were recruited via social media and snowball sampling. Qualitative findings provide potential sociocultural predictors of disordered eating that should be further explored, such as bicultural identity and family pressures/comments toward appearance. Secondly, themes from the EES-R indicate adding emotion of shame and considering identity-related stress. The current study provides prevalence data and future directions of research on widely used eating pathology and appearance attitude measurements for A-MENA American women.

Muscle Dysmorphia (MD) and its psychological impacts on women, especially within sexual minorities, are still relatively understudied. The objective of this study was to compare the relationship of MD symptoms and psychological distress between heterosexual women and lesbian/bisexual women. Our sample consisted of 479 Brazilian cisgender women from the community, aged between 18 and 70 years (M = 32.78; SD = 10.45). Among them, 327 (68.27 %) identified as heterosexual, 134 (27.98 %) as bisexual, and 18 (3.76 %) as lesbian. To ensure there was no bias due to measurement error, the psychometric properties of the instruments in the sample were tested, and invariance between the groups was assessed. t-tests, structural equation modeling, and latent profile analyses were conducted to comprehend the differences between the groups. The results indicated significant differences and a greater severity of MD symptoms and distress for lesbian/bisexual women. The implications of these results are discussed, emphasizing the need for further exploration of MD studies within sexual minorities.

Objective

To identify current strategies used by first-year university students to lose weight, maintain weight, or change their body shape.

Methods

First-year university students (n = 661) completed an open-ended, web-based survey. Cross-sectional data were analyzed qualitatively using a reflexive thematic approach to identify strategies used to lose weight, maintain weight, or alter body shape/composition. Thematic maps were constructed for each weight- and shape-related goal.

Results

Four main types of strategies were used to achieve all three weight or shape-related goals among first-year college students: changes in diet, changes in exercise, self-monitoring, and disordered eating. One behavioral strategy observed across all weight-related goals was prioritizing protein consumption, including protein gained from supplementation. However, there were also differences in strategies by weight- or shape-related goal. For example, only participants aiming to lose or maintain weight reported mindful strategies for monitoring diet. Individuals aiming to alter body composition reported heterogeneity in goal-related intentions, targeting specific body parts through exercise, and extensive supplement use.

Conclusions

First-year college students use a variety of strategies to manage their weight and shape. Some strategies were observed across goals, whereas others are specific to the weight- or shape-related goal. More research is needed to understand the impacts, both positive and negative, of using the strategies identified in the present study.

Food and alcohol disturbance (FAD) refers to the intersection of alcohol- and eating-related motives and behaviors, such as restricting food intake before or during alcohol use to offset caloric intake or to enhance intoxication. Valid assessment is critical for advancing research on FAD. We tested the factor structure, group invariance, and concurrent validity of the College Eating and Drinking Behavior Scale (CEDBS) in a large college student sample (n = 2610; Mage = 20.95, SD = 4.65; 71.8% female; 77% White; 86% non-Hispanic). Participants completed measures assessing antecedents of alcohol use (i.e., protective behavioral strategies and drinking motives), negative alcohol-related consequences, alcohol use severity, and risk for eating disorder. The 3-factor model of the 21-item CEDBS provided an adequate fit to the data (e.g., CFI = 0.916). These factors include Alternative Methods (4 items; “Use laxative prior to drinking alcohol”), Offset Calories (7 items; “Restrict calories prior to drinking to help maintain your figure”), and Quicker Intoxication (10 items; “Not eating before drinking alcohol because it gives you the best buzz”). The CEDBS was scalar invariant across subgroups of participants based on age, sex, race/ethnicity, socioeconomic status, sexual orientation, and political orientation. Quicker Intoxication was most strongly related to risk factors and negative consequences for alcohol (r = 0.204–0.379, all ps < 0.01), and Offset Calories was most strongly related to risk for eating disorders (r = 0.349, p < .01). These findings further support the CEDBS to assess FAD among college students.

Objective

To assess whether attentional bias to food cues and appetitive traits are independently and interactively associated with adiposity in adolescents.

Method

Eighty-five adolescents, 14–17-years had their attentional bias to food images measured in a sated state by computing eye tracking measures of attention (first fixation duration, cumulative fixation duration) to food and control distractor images that bordered a computer game. Parents reported adolescent appetitive traits including the food approach domains of enjoyment of food, food responsiveness, emotional overeating, and the food avoidance domains of satiety responsiveness and emotional overeating through the Children's Eating Behavior Questionnaire.

Results

First fixation bias to food cues was positively associated with enjoyment of food, and negatively associated with satiety responsiveness. In a series of regression models adjusted for relevant covariates, first fixation bias to food cues (β = 0.83, p = 0.007), higher food responsiveness (β = 0.74, p < 0.001), higher emotional overeating (β = 0.51, p = 0.002), and a composite appetite score (β = 1.42, p < 0.001) were each significantly associated with greater BMI z-scores. In models assessing the interactive effects between attentional bias and appetitive traits, higher first fixation bias to food cues interacted synergistically with food responsiveness and emotional overeating in relation to BMI z-score. A synergistic interaction between first fixation bias to food cues and the composite appetite score in relation to BMI z-score was also observed.

Conclusion

Individuals with high attentional bias to food cues and obesogenic appetitive traits may be particularly susceptible to weight gain.

Food and alcohol disturbance (FAD) is an understudied form of disordered eating, in which the consumption of calories is restricted in preparation for drinking alcohol. Guided by previous literature, the present study examined the direct, indirect, and interactive relationships between social media use, anxiety, social support, FAD, and disordered eating among young adults. Recruited from a large southwestern public university, the sample included 679 undergraduate students who completed an online survey in spring of 2022 and who indicated that they consume alcohol and are 18 to 29 years old. Two moderated mediation analyses assessed the indirect effects of anxiety on the relationships between social media use with FAD and disordered eating, and the conditional contribution of social support. Results indicated that social media use was related to disordered eating both directly and indirectly through anxiety, but it was only related to FAD through anxiety. Furthermore, indirect effects connecting social media use to FAD and disordered eating were conditional upon social support. Our findings suggest FAD and disordered eating may be coping mechanisms for anxiety stemming from social media exposure, though these associations appear to be attenuated when social support is high. As such, these findings may be relevant for shaping future intervention and prevention efforts for emerging adults experiencing FAD and disordered eating.

Introduction

Individuals with obesity who smoke cigarettes have increased risk of morbidity and mortality. The goal of the current study was to inform the development of a multiple health behavior change intervention designed to facilitate smoking cessation while also targeting weight gain.

Methods

Four qualitative focus groups were conducted with individuals who smoked cigarettes and had overweight or obesity (n = 16) to explore the combined effects of smoking and obesity, past attempts to quit smoking or lose weight, and preferences for a combined health intervention.

Results

Focus groups converged on five themes including: the interactive effects of weight and smoking; lack of experience with evidence-based weight loss approaches; a desire and expectation to lose weight quickly; rapid weight gain during past attempts at smoking cessation; and interest in a multiple health behavior change intervention with weight management preceding smoking cessation and an emphasis on planning for the future and receiving encouragement and support.

Conclusions

Groups provided insight into key topics to highlight in a combined intervention and key issues that have interfered with success in both domains.

Introduction

A more comprehensive understanding of the factors regarding weight control in individuals with overweight or obesity after quitting smoking is needed. The study aimed to analyze the changes of in-treatment variables during a smoking cessation intervention and examine their impact on weight.

Methods

A total of 120 individuals who smoke with overweight or obesity (M_BMI = 31.75 ± 4.31; 54.16 % female) participated in a cognitive-behavioral therapy for smoking cessation and weight control or the same treatment plus contingency management. Weight, smoking variables (cotinine and continuous abstinence), eating behaviors (appetite, grazing), exercise, and sleep were assessed weekly throughout the treatment.

Results

More participants gained weight over time with reduced nicotine use or abstinence. There was a tendency during treatment to increase appetite and exercise time, while grazing episodes and sleeping hours remained stable. Higher baseline weight (p < .001), greater cotinine reduction (p = .021) and time (p = .009) were associated with greater weight gain, while more hours of exercise (p = .003), no appetite changes (p = .003) and diminished appetite (p < .001) were associated with less gain over the treatment. Both treatment conditions showed similar results in all in-treatment variables.

Discussion

Individuals with overweight and obesity with higher baseline weight and higher baseline cotinine levels during smoking cessation interventions may require special attention to improve weight outcomes. Exercise and appetite regulation may be useful for mitigating weight gain in smoking cessation interventions for individuals with overweight or obesity.

Eating disorder (ED) behaviors and depression are associated with numerous negative outcomes, including lower quality of life and functional impairment. College women are at elevated risk for both. Prior research indicates ED behaviors, including binge eating, self-induced vomiting, and fasting, predict increases in future depressive symptoms. However, symptom heterogeneity in EDs is common, and all disordered eating, or its associated distress, cannot be captured by the endorsement of behaviors. Impairment that results from ED behaviors may be a comparable, or stronger, predictor of depressive symptoms. We sought to characterize the longitudinal relationship between ED-related functional impairment, ED behaviors, and depressive symptoms. College-aged women [N = 304; 72 % white, mean (SD) age = 18.45 (0.88)] completed an online survey in August (baseline), and then three months later in November (follow-up). Baseline ED-related functional impairment, but not baseline ED behaviors, significantly predicted depressive symptoms at follow-up, controlling for baseline depressive symptoms, negative affect, and body mass index. Findings indicate ED-related functional impairment is a risk factor for increases in depressive symptoms across one semester of college, irrespective of ED behavior engagement, weight status, and dispositional negative affect. Intervening upon ED-related functional impairment may reduce or prevent future depressive symptoms among college-aged women.

This longitudinal study examined whether body image concerns (general; sporting) predicted eating disorder psychopathology, and whether the link differed according to nature of sport engagement. Participants were competitive sports engagers, non-competitive sports engagers, or sports non-engagers. At baseline, 510 adults completed online measures of sports demographics, eating psychopathology and body image. Eating psychopathology and body image measures were taken at follow-up (6 months later). Competitive sports engagers had better body image than the other two groups. Poorer body appreciation and better appearance-related body image predicted higher eating disorder psychopathology. Engaging in sports competitively may be beneficial for body image. However, positive appearance-related sporting body image may pose a risk for later eating psychopathology.
