The role of implied motion in engaging audiences for health promotion: encouraging naps on a college campus

Assessing food availability and healthier options in an urban Chinese university: a case study using the Chinese Nutrition Environment Measurement Survey for Stores (C-NEMS-S)

Young adults (18-24 years) in universities are frequently exposed to an environment that promotes unhealthy eating behaviors. Using a validated tool, the Chinese Nutrition Environment Measurement Survey for Stores (C-NEMS-S), we assess the food availability and healthier options in a large, urban Chinese university. We employed C-NEMS-S for scoring criteria and weighting. A total of 52 on-campus canteen outlets were audited in an urban university located in Shijiazhuang City, China. General food outlets (n 43) and self-served food outlets (n 7) were further categorized into eight subtypes. Beverage outlets (n 2) were discussed separately from food outlets. C-NEMS-S scores were significantly different across food outlet types (P = 0.0024), especially between noodle and rice outlets (P = 0.0415). Food availability scores for starchy tubers (P < 0.001), dry beans (P < 0.001), vegetables (P = 0.0225), and fruits (P < 0.001) were significantly different across food outlet subtypes. Healthier options were scarce and only appeared in "grains" (n 2) and "meat and poultry" (n 2) categories. Further research on improving the accustomed audit tool and assessing university student diet quality is warranted.

Food on the Move: The Impact of Implied Motion in Pictures on Food Perceptions through Anticipated Pleasure of Consumption

To tackle obesity, upgrading the image of healthy food is increasingly relevant. Rather than focusing on long-term benefits, an effective way to promote healthy food consumption through visual advertising is to increase its pleasure perception. We investigate whether implied motion, a popular trend in food pictures, affects food perceptions through anticipated consumption pleasure. Prior research shows that motion affects food perceptions, but these studies focused on limited food categories, using experiments with a single food stimulus, and mainly showing unhealthy food effects. Therefore, we aim to (1) replicate prior findings on the effects of food in motion on appeal, tastiness, healthiness, and freshness perceptions; (2) examine whether these effects differ for healthy and unhealthy food; and (3) investigate whether anticipated pleasure of consumption drives the effects of implied motion on food perceptions. Three between-subjects experiments (N = 626) reveal no evidence for the effectiveness of motion (vs. no motion) across a large variety of food products. We further show no differential effects for healthy versus unhealthy foods. Moreover, implied motion does not increase appeal or taste perceptions through anticipated pleasure. Considering the current replication crisis, these findings provide more nuanced insights into the effectiveness of motion in visual food advertising.

Take a Bite! The Effect of Bitten Food in Pictures on Product Attitudes, Purchase Intentions, and Willingness to Pay

Food pictures in advertisements, on packages, and on social media often display food with a bite in it. We investigated the effect of pictures of food with a bite (vs. no bite) on product attitudes, purchase intentions, and willingness to pay. In two online experimental studies we tested this effect for both pictures without context, as well as pictures in an advertisement. We also investigated two theories that could lead to opposite effects: consumer contamination and embodied mental simulation. We found that a picture of food with a bite (vs. no bite) resulted in lower purchase intentions, and that this effect was mediated by disgust (i.e., consumer contamination). Furthermore, we found an interaction effect of picture type (i.e., bite vs. no bite) and context (i.e., no context vs. advertisement) on purchase intentions: the effect of picture type on purchase intentions was attenuated when the picture appeared in an advertisement (vs. when the picture is shown without context). We found similar effects on product attitudes and willingness to pay. Lastly, a picture of food with a bite (vs. no bite) had no effect on embodied mental simulation. Field practitioners are advised to take caution when using pictures of bitten food as this may lead to unfavorable consumer responses because of a feeling if disgust.

The use of the health belief model to assess U.S. college students' perceptions of COVID-19 and adherence to preventive measures

Background: This study utilized the Health Belief Model to examine college students’ perceptions of the COVID-19 pandemic. It examined the extent to which the Health Belief Model and perceived threat are associated with the adoption of COVID-19 preventive measures among college students.

Design and Methods: An online questionnaire was utilized and sent to a simple random sample of college students at a large Midwestern university in the United States between May and July of 2020. The number of undergraduate and graduate students who participated in this study was 1,723.

Results: The study found that the Health Belief Model and perceived threat are significantly associated with COVID-19 preventive measures. College students with higher Health Belief Model scores were more likely to adhere to COVID-19 preventive measures than those with lower scores. College students also reported high cues to action and low perceived barriers to most of the COVID-19 preventive measures.

Conclusion: Applying the Health Belief Model is crucial for health professionals and university administrators for developing effective communication messages for COVID-19 prevention and future health outbreaks.

Determinants of sleep quality in college students: A literature review

PURPOSE

To review the various determinants of sleep quality among college students.

METHODS

The PubMed, Web of Science and Cochrane Library databases were searched with the search string "sleep quality" AND "college students" for articles published between January 2007 and October 2017. Articles were excluded if they (1) examined sleep quality as a risk factor for other outcomes or (2) involved inpatients or participants under medical care.

RESULTS

The 112 identified studies were classified into categories according to the investigated determinants and their effect on sleep quality. Physical activity and healthy social relations improved sleep quality, while caffeine intake, stress and irregular sleep-wake patterns decreased sleep quality. Less consistent results were reported regarding eating habits and sleep knowledge, while proper napping during the day might improve overall sleep quality.

CONCLUSIONS

College students are vulnerable to different risk factors for sleep quality. When designing interventions to improve sleep quality among college students, the main determinants need to be taken into consideration.

Health Behaviors of Student Community Research Partners When Designing and Implementing a Healthy Lifestyle Intervention on College Campuses

Few studies work with college students as equal partners in all aspects of Community-Based Participatory Research (CBPR) and even less evaluate behaviors of those college partners. The current study aimed to examine health behaviors of students by designing and implementing a peer-led, social marketing campaign (Get Fruved) to promote healthier lifestyles on their campuses. Enrolled students (n = 376) were trained to either design and implement a health promotion intervention (Social Marketing and Environmental Interventionists; SMEI, n = 78), be peer mentors (PM; n = 205), or serve as control participants (n = 93). Students' behaviors (dietary, activity, and stress) and anthropometrics were assessed at baseline, 6 months, and 12 months. The population was predominately Caucasian, female, and between 19 and 20 years old. On average, fruit and vegetable consumption slightly decreased across all time points for each group with control at a larger decline. Students International Physical Activity Questionnaire (IPAQ) scores showed students met recommended amounts of activity throughout the intervention, with males reporting higher activity levels. Cohen's Perceived Stress Scale (PSS) analyses indicated 19 year olds had higher stress along with females had higher than males. Students involved in a CBPR approach to be trained, design, and implement a lifestyle intervention can achieve maintenance of health behaviors throughout a college year when compared to control students.

Using the Elaboration Likelihood Model to Address Drunkorexia among College Students

BACKGROUND

The many consequences related to alcohol consumption among college students are well documented. Drunkorexia, a relatively new term and area of research, is characterized by skipping meals to reduce caloric intake and/or exercising excessively in attempt to compensate for calories associated with high volume drinking.

OBJECTIVE

The objective of this study was to use the Elaboration Likelihood Model to compare the impact of central and peripheral prevention messages on alcohol consumption and drunkorexic behavior.

METHODS

Researchers employed a quasi-experimental design, collecting pre- or post-test data from 172 college students living in residence halls at a large Midwestern university, to assess the impact of the prevention messages. Participants in the treatment groups received the message in person (flyer), through email, and via a text message in weekly increments.

RESULTS

Results showed that participants exposed to the peripherally framed message decreased the frequency of their alcohol consumption over a 30-day period (p =.003), the number of drinks they consumed the last time they drank (p =.029), the frequency they had more than five drinks over a 30-day period (p =.019), as well as the maximum number of drinks they had on any occasion in the past 30 days (p =.014). Conclusions/Importance: While more research is needed in this area, the findings from this study indicate that researchers and practitioners should design peripheral (short and succinct), rather than central (complex and detailed), messages to prevent drunkorexia and its associated behaviors.
