Does buffet choice architecture affect intake? The effect of relocating butter at a breakfast buffet on food intake

The aim of this study was to investigate if a changed default reduces the intake of butter among students at a breakfast buffet. Students were divided into two groups and served themselves from a breakfast buffet. The control group was offered a buffet where the butter was easily accessible, whereas the intervention group was offered a buffet where a request had to be made for butter. Single packed portions of butter taken from each part of the buffet, the number of students, and the number of habitual users in each group were recorded. At the regular buffet, 67 of 115 students were habitual butter users and 81 packs of butter were taken. At the buffet with the changed default, 16 of the 56 students were habitual butter users. Seventeen packs of butter were taken from the buffet. Slightly displacing butter at a breakfast buffet and forcing students to ask for that option significantly reduced uptake.

In search of diners responsive to health cues: Insights from U.S. consumers

Many consumers rely on summary statistics offered by online and mobile platforms to attain nutrition information on menu items. While positive (vs. negative) summary cues garner more favorable consumer responses, this research provides a more nuanced understanding of this effect by examining the moderating role of two individual-level characteristics: health-consciousness and need for status. Two MTurk samples (Study 1: n = 142, Study 2: n = 119) were recruited in 2018. Findings from Study 1 suggest that health-conscious (vs. less health-conscious) consumers show a wider gap in perceived healthiness of a menu item in response to the valence of a health cue. This greater gap translates into more polarized attitudes toward the menu item. Findings from Study 2 indicate that consumers high (vs. low) in need for status exhibit less favorable attitudes toward a menu item with a negative health cue. Theoretical and managerial implications are discussed.     

The influence of attitudes towards healthy eating on food consumption when travelling

This study explores tourists' attitude towards healthy eating and its influence on their travel eating behaviour. Based on focus group interviews and literature review, two instruments were developed to measure healthy eating attitude and travel eating behaviour. Factor analysis results revealed two healthy eating attitude factors (‘food content and nutrients’ and ‘balanced diet and eating habit’), and five travel eating behaviour factors (‘novelty’, ‘risk avoidance’, ‘health steadfastness’, ‘familiarity’, and ‘food supplement and medicine’). The relationships among the factors were examined using structural equation modelling. The findings revealed that respondents who had a stronger attitude towards ‘balanced diet and eating habit’ tended to be more motivated by the ‘novelty’ factor; whereas ‘risk avoidance’, ‘health steadfastness’ and ‘familiarity’ were found to be associated with a stronger attitude towards ‘food content and nutrient’. The findings suggest that the healthy eating attitude construct is multidimensional and healthy eating conscious tourists should not be treated as a homogeneous group.     

Time orientation and construal level: effects on eating and exercising behaviour and preferences

Eating and exercising behaviour are both characterized by immediate and future consequences. Consequently, consideration of these consequences (i.e. time orientation) predicts eating and exercising behaviour. We investigate whether construal level acts as an underlying mechanism of these relations. Students (N = 101) completed measures of consideration of immediate and future consequences (i.e. CFC‐food and CFC‐exercise), construal level, eating and exercising behaviour and preferences. For self‐reported eating and exercising behaviour, only direct effects of consideration of immediate and future consequences were found. For eating preferences, however, there was evidence of an indirect effect through construal level. A stronger tendency to consider future consequences led to a stronger preference for utilitarian (as compared with hedonic) food products through a more abstract construal level. All in all, construal level partially explains the differential relations between consideration of immediate and future consequences and eating and exercising behaviour and preferences.     

THE 'BROKEN WINDOWS' THEORY AND THE NEW YORK EXPERIENCE RECONSIDERED

The undeniable success of order-maintenance policing (also community policing or broken windows policing) is despite the deficiency in the theory which propelled the practice into policy: Wilson and Kelling's broken windows theory. We discuss what is wrong with the theory and why it nevertheless works when put into practice.     

Anxiety disorders,major depressive disorder and the dynamic relationship between these conditions: treatment patterns and cost analysis

Abstract

Objective: To determine the treatment pattern and impact on healthcare costs of anxiety disorders and major depressive disorder (MDD), and influence of their concomitance and subsequence.

Methods: A retrospective cohort study was conducted using a US reimbursement claims database. Adult patients with an incident diagnosis of anxiety or MDD (index date) were included. Their sociodemographic data, diagnoses, healthcare resource use and associated costs were collected over the 6 months preceding and 12 months following index date.

Results: A total of 599,624 patients were identified and included. Patients with phobia or post-traumatic stress disorder had the highest 12-month costs ($8,442 and $8,383, respectively). Patients with social anxiety disorder had the lowest costs ($3,772); generalized anxiety disorder ($6,472) incurred costs similar to MDD ($7,170). Costs were substantially increased with emergence of anxiety during follow-up in MDD patients ($10,031) or emergence of MDD in anxiety patients ($9,387). This was not observed in patients with both anxiety and MDD at index date ($6,148).

Conclusion: This study confirms the high burden of costs of anxiety, which were within the same range as MDD. Interestingly, the emergence of anxiety or MDD in the year following a first diagnosis of MDD or anxiety, respectively, increased costs substantially. Major limitations were short follow-up and lack of absenteeism costs.     

Clinical characteristics and resource utilization of patients with bipolar disorder who have frequent psychiatric interventions

Abstract

Objective:

To compare the demographics, clinical characteristics and resource utilization of patients with bipolar disorder who required frequent psychiatric interventions (FPIs) with those needing fewer interventions in the Duke Healthcare System database between 1999 and 2005.

Methods:

This retrospective analysis was conducted using electronic medical records of bipolar patients with FPIs, defined as having ≥4 clinically significant events (CSEs) in any 12-month period while in the Duke University Healthcare System. CSEs were composed of emergency room visits, inpatient hospitalizations, or a change in psychotropic medication due to psychiatric symptoms (score ≥4 on the Clinical Global Impressions–Severity scale). Data were compared between patients with and without FPIs.

Results:

Of 632 patients with bipolar disorder 52.5% were identified as having FPIs. These patients were younger and more often female and African American than those with fewer interventions (p?<?0.01 for all). Patients with FPIs were generally prescribed more psychotropic and non-psychotropic medications, utilized more healthcare resources and experienced more psychiatric co-morbidities than those who did not require FPIs (p?<?0.01 for all).

Limitations:

These results are from a single healthcare system and may not be generalizable to all patients with bipolar disorder. This analysis was retrospective and relied on availability of adequate information recording and coding of diagnoses by physicians.

Conclusions:

Patients with bipolar disorder who required FPIs were significantly different from those with fewer clinically defined interventions with respect to their demographic and clinical characteristics and prescribed medications.     

A State-of-the-Art Analysis of Food Consumption Studies

Abstract

A review of empirical food consumption studies is offered in this paper. A large number of recent food consumption studies from the areas of food and nutritional science, psychology, social psychology, sociology, anthropology, and consumer research are brought together. Twelve research themes are identified from the literature review and key findings and their implications are discussed. A heuristic and evaluative classification is developed to get a systematic understanding of the research issues covered by current food consumption research. A few suggestions for future food consumption research are mentioned on the basis of research gaps identified by the classification. To conclude, the theoretical prospects of studying food-related value conflicts and cross-cultural differences in emotional eating are spelled out in detail.
