Anxiety sensitivity in relation to eating expectancies among college students

The relationship between stress, anxiety and eating behavior among Chinese students: a cross-sectional study

Background

The expansion of higher education and the growing number of college students have led to increased awareness of mental health issues such as stress, anxiety, and eating disorders. In China, the educational system and cultural expectations contribute to the stress experienced by college students. This study aims to clarify the role of anxiety as a mediator in the relationship between stress and eating behaviors among Chinese college students.

Methods

This study utilized data from the 2021 Psychology and Behavior Investigation of Chinese Residents, which included 1,672 college students under the age of 25. The analysis methods comprised descriptive statistics, t-tests, Pearson correlation analyses, and mediation effect analysis.

Results

The findings indicate that Chinese college students experience high levels of stress, with long-term stress slightly exceeding short-term stress. Both types of stress were positively correlated with increased anxiety and the adoption of unhealthy eating behaviors. Anxiety was identified as a significant mediator, accounting for 28.3% of the relationship between long-term stress and eating behavior (95% CI = 0.058-0.183). The mediation effect of short-term stress on eating behavior through anxiety was also significant, explaining 61.4% of the total effect (95% CI = 0.185-0.327).

Conclusion

The study underscores the importance of stress management and mental health services for college students. It recommends a comprehensive approach to reducing external pressures, managing anxiety, and promoting healthy eating behaviors among college students. Suggestions include expanding employment opportunities, providing career guidance, enhancing campus and societal support for holistic development, strengthening mental health services, leveraging artificial intelligence technologies, educating on healthy lifestyles, and implementing targeted health promotion programs.

Clarifying the pathway from anxiety sensitivity to binge eating: The mediating role of depressive symptoms in a 3-week, 3-wave longitudinal study of undergraduates

Anxiety sensitivity (AS) - characterized by a persistent fear that arousal-related bodily sensations will lead to serious cognitive, physical, and/or social consequences - is associated with various psychopathologies, including depressive symptoms and binge eating. This 3-week, 3-wave longitudinal study examined the relation between AS (including its global AS factor and lower-order AS cognitive, physical, and social concern dimensions), depressive symptoms, and binge eating among 410 undergraduates from two universities. Using generalized estimating equation models, we found that global AS, AS social concerns, and depressive symptoms predicted binge eating during any given week. Mediation analyses showed that global AS (as a latent variable with its lower-order AS dimensions as indicators), AS cognitive concerns, and AS physical concerns at Wave 1 predicted subsequent increases in depressive symptoms at Wave 2, which, in turn, led to increases in binge eating at Wave 3. Findings contribute to a better understanding of the interplay between AS, depressive symptoms, and binge eating, highlighting the role of binge eating as a potential coping mechanism for individuals with high AS, particularly in managing depressive symptoms. This study underscores the importance of AS-targeted intervention and prevention efforts in addressing depressive symptoms and binge eating.

Beyond generalized anxiety: the association of anxiety sensitivity with disordered eating

BACKGROUND

Anxiety and eating disorders (EDs) are rising at alarming rates. These mental health disorders are often comorbid, yet the factors associated with their comorbidity are not well understood. The present study examined a theoretical model of the pathways and relative associations of anxiety sensitivity (AS) with different dimensions of ED risk, controlling for generalized anxiety.

METHODS

Participants (N = 795) were undergraduate students with an average age of 21 (SD = 4.02), predominantly female (71%), and Hispanic (71.8%). Participants completed an online survey with established measures of AS (i.e., Anxiety Sensitivity Index-3; ASI-3), general anxiety (i.e., Beck Anxiety Inventory; BAI), and eating behaviors (i.e., Eating Attitudes Test-26; EAT-26).

RESULTS

The results of our structural equation models indicated that AS subscales were significantly associated with dimensions of the EAT-26, even when controlling for generalized anxiety. Specifically, the ASI-3 factors reflecting cognitive and social concerns provided the most consistent significant associations with EDs. Whereas reporting higher cognitive concerns was associated with higher ED symptoms (e.g., reporting the urge to vomit after a meal), reporting higher social concerns was associated with fewer ED symptoms. These differential results may suggest risk and resilience pathways and potential protective or buffering effects of social concerns on ED risk.

DISCUSSION

Findings advance understanding of the role of AS in the comorbidity of anxiety and EDs, demonstrating the strong association of AS with ED pathology. These findings provide cognitive indicators for transdiagnostic therapeutic intervention in order to reduce the risk of EDs.

The association between anxiety sensitivity and food cravings among individuals seeking treatment for weight-related behaviors

BACKGROUND

A better understanding of risk-factors associated with state-like food cravings may be one clinically relevant component in an effort to better understand obesity. Existing work has shown anxiety sensitivity (AS) to be a significant risk factor for increased cravings across a variety of health behaviors (e.g., smoking, alcohol use). Yet, no work has examined the relationship between AS and state-like food cravings. Therefore, the current study sought to examine the association between AS and a variety of state-like food cravings, including: (1) an intense desire to eat, (2) anticipation of relief from negative states and feelings/improvement in mood that may result from eating, (3) obsessive preoccupation with food or lack of control over eating, and (4) craving as a physiological state.

METHODS

Participants included 161 (Mage = 31.58, SD = 10.71; 60.9 % female) individuals seeking treatment for weight-related behaviors.

RESULTS

Results indicated that elevated AS was associated with reinforcement-based and physiological food cravings.

CONCLUSION

Our findings indicate that there may be clinical utility in screening for AS among individuals seeking treatment for weight-related behaviors in efforts to better understand specific types of food craving.

Computer-delivered intervention for individuals with obesity and elevated anxiety sensitivity: feasibility, acceptability, and initial test

Obesity is one the fastest growing public health problems related to numerous chronic diseases and frequently co-occurs with negative mood states. One promising approach to address the heterogeneity of affective vulnerabilities and obesity is to focus on processes (e.g. anxiety sensitivity [AS]) that underpin both conditions. Thus, this study aimed to evaluate the feasibility, acceptability, and initial efficacy of a brief, computer-delivered AS reduction program (AST) for adults with obesity and elevated AS. Participants were 131 individuals with obesity and elevated AS who received either AST or a health information control (HC). Latent growth curve modeling was utilized to examine the effect of treatment condition on change in AS, emotional eating, expectancies of eating to manage mood, and exercise self-efficacy from baseline to 1-week, 2-weeks, and 1-month follow-up. Results indicated it was feasible to recruit and retain individuals with obesity and elevated AS through the 1-month follow-up. Positive qualitative feedback was also provided for both AST and HC. AST was a statistically significant predictor of change in expectancies of eating to manage negative affect. No other statistically significant treatment effects were indicated. Current data provide initial empirical support for future work focused on persons with obesity and elevated AS.

Anxiety Sensitivity and Fatigue Severity Among Adults with Chronic Low Back Pain

BACKGROUND

The combined impact of chronic low back pain (CLBP) and fatigue severity is associated with increased burden and worsened symptoms. Understanding factors that may contribute to and maintain fatigue severity among individuals with CLBP is needed to isolate intervention modalities.

METHODS

The current study sought to investigate the role of anxiety sensitivity (AS) in terms of fatigue severity among 1,663 adults (70.0% female, M _age = 44.5 years, SD = 11.87) with current mild to severe CLBP as well as a subset of the sample with clinically significant fatigue (n = 778).

RESULTS

Results indicated AS was a positively and statistically significant predictor of fatigue severity among the entire sample and the subset of the sample with clinically significant fatigue.

CONCLUSIONS

These cross-sectional data highlight the potential promise of AS as an underrecognized cognitive vulnerability for greater fatigue severity among those with CLBP.

Anxiety Sensitivity and Fast-Food Ordering Habits Among Black Adults

Background

Black adults experience high rates of overweight/obesity, which is linked to chronic diseases and is exacerbated by fast-food consumption. Anxiety sensitivity, a relative stable fear of anxiety-related sensations, has been linked to high caloric intake. Here, we examine whether anxiety sensitivity is associated with fast-food ordering habits within a convenience sample of Black adults.

Methods

Of 124 adults (79.4% women; M_age=49.3±11.6; 84.8% overweight/obese), 107 (86.3%) reported eating from a fast-food restaurant in the last month. Participants completed the Anxiety Sensitivity-Index 3, which has a total score and physical, cognitive, and social concerns subscales. Investigator-generated items queried frequency of ordering "supersized" quantities of fast-food (e.g., cheeseburgers, fries), and healthy items (e.g., salads, oatmeal, yogurt), respectively, from "never" to "always." Covariate-adjusted ordinal logistic regression models were used to assess relations between measures of interest.

Results

Anxiety sensitivity (total and physical concerns) was associated with greater odds of more frequently ordering supersized unhealthy fast-food; and anxiety sensitivity (total and cognitive concerns) was associated with lower odds of more frequently ordering healthy items from fast-food restaurants.

Conclusions

Results suggest that adults with greater anxiety sensitivity may engage in fast-food ordering habits that can contribute to the overweight/obesity epidemic. Future studies should replicate results and determine the potential for anxiety sensitivity-reduction interventions to affect dietary choices that contribute to overweight/obesity.

Negative Mood Is Associated with Diet and Dietary Antioxidants in University Students During the Menstrual Cycle: A Cross-Sectional Study from Guangzhou, China

Postpubescent females may have negative mood or premenstrual syndrome during the menstrual cycle; with the emotional and physical symptoms interfering with their quality of life. Little is known about the relationship of dietary behaviors and dietary antioxidant intake with negative mood or premenstrual syndrome in university students in China; so we explored the relationship between negative mood and dietary behavior in female university students during the three menstrual cycle phases. Random sampling was used to enroll 88 individuals from a university in Guangzhou; China in the study. Data were collected using self-administered questionnaires. Descriptive statistics and multiple logistic regression analyses were performed. During the menstrual phase, tea, black coffee and carbonated beverage intake was higher in the group with a high negative affect scale score than in the low score group (p < 0.05). Likewise; during the premenstrual phase, fresh fruit (banana and red Chinese dates) intake was higher in the group with a high negative affect scale score than in the low-score group (p < 0.05). The logistic regression analysis results showed that negative mood was positively associated with tea, coffee, and carbonated beverage intake during the menstrual phase (β = 0.21, p = 0.0453, odds ratio = 1.23), and negative mood was positively associated with banana and red Chinese dates intake during the premenstrual phase (β = 0.59, p = 0.0172, odds ratio = 1.81). Our results suggest that negative mood may be associated with diet and specific food in university postpubescent females.
