The relationship between the environment and physical activity-related motivational trajectories.

The study explores motivational profiles for physical activity, using self-determination theory's full continuum of motivational regulations, and examines their stability over three months. Furthermore, it investigates whether physical environment and community characteristics are associated with transitioning between profiles, as well as the sociodemographic differences in these motivational transition pathways. Data were collected from 305 U.

Motive perception pathways to the release of personal information to healthcare organizations.

Background: The goal of the study is to assess the downstream effects of who requests personal information from individuals for artificial intelligence-(AI) based healthcare research purposes-be it a pharmaceutical company (as an example of a for-profit organization) or a university hospital (as an example of a not-for-profit organization)-as well as their boundary conditions on individuals' likelihood to release personal information about their health. For the latter, the study considers two dimensions: the tendency to self-disclose (which is aimed to be high so that AI applications can reach their full potential) and the tendency to falsify (which is aimed to be low so that AI applications are based on both valid and reliable data).

Methods: Across three experimental studies with Amazon Mechanical Turk workers from the U.

Perceived similarity determines social comparison effects of more and less physically active others.

This research tested whether the effects of physical activity (PA) comparisons depend on the perceived similarity to comparison standards. In 3 experimental studies, participants compared themselves to a more or a less physically active person. Results showed that perceived similarity determined comparison outcomes: Participants' PA self-evaluation and self-efficacy were higher when focusing on similarities with more (vs less) (Study 1) and dissimilarities with less (vs more) active others (Study 1 and 2).

Effects of Gamified Smartphone Applications on Physical Activity: A Systematic Review and Meta-Analysis.

Introduction: This systematic review and meta-analysis aims to examine the impacts of standalone gamified smartphone application-delivered interventions on physical activity.

Methods: Web of Science, Scopus, PubMed, PsycINFO, and ACM Digital Library were searched for publications that were published between January 1, 2008 and August 31, 2021. Eligibility criteria were RCTs or single-arm pre-to-post interventions delivered by standalone gamified applications and targeting physical activity.

Compliance with medical recommendations depending on the use of artificial intelligence as a diagnostic method.

Background: Advanced analytics, such as artificial intelligence (AI), increasingly gain relevance in medicine. However, patients' responses to the involvement of AI in the care process remains largely unclear. The study aims to explore whether individuals were more likely to follow a recommendation when a physician used AI in the diagnostic process considering a highly (vs.

Determinants of Fitness App Usage and Moderating Impacts of Education-, Motivation-, and Gamification-Related App Features on Physical Activity Intentions: Cross-sectional Survey Study.

Background: Smartphone fitness apps are considered promising tools for promoting physical activity and health. However, it is unclear which user-perceived factors and app features encourage users to download apps with the intention of being physically active.

Objective: Building on the second version of the Unified Theory of Acceptance and Use of Technology, this study aims to examine the association of the seven determinants of the second version of the Unified Theory of Acceptance and Use of Technology with the app usage intentions of the individuals and their behavioral intentions of being physically active as well as the moderating effects of different smartphone fitness app features (ie, education, motivation, and gamification related) and individual differences (ie, age, gender, and experience) on these intentions.

Appearance Comparisons and Eating Pathology: A Moderated Serial Mediation Analysis Exploring Body Image Flexibility and Body Appreciation as Mediators and Self-Compassion as Moderator.

Comparing one's body against the bodies of others is related to lower positive body image and higher eating pathology. Underlying mechanisms as well as protective factors of these relationships are yet to be discovered. The present study examined body image flexibility and body appreciation as potential mediators of the association between appearance comparisons and eating disorder psychopathology.

Determinants of physical activity maintenance during the Covid-19 pandemic: a focus on fitness apps.

There are various health benefits of regular physical activity (PA) and health risks of sedentariness. The Covid-19 pandemic may have decreased PA and increased sedentariness for several reasons (e.g.

Restrained eaters' consumption of dietary forbidden and permitted foods after exposure to incidental fitness cues.

The purpose of this research is to investigate the influence of incidental fitness cues on caloric food intake in restrained (vs. unrestrained) eaters. The authors show that the effect of incidental fitness cues (made salient via a priming procedure in a seemingly unrelated study prior to the main study) on caloric food intake differs between dietary forbidden and permitted foods.

Exploring the meaning of growing food in community gardens to South African township residents: A photovoice study.

The purpose of this research is to explore the motivation for, and potential effects of, participation in a township community garden. The authors conducted a photovoice study with 18 South African township residents who grew their own food as part of a community gardening program in the Western Cape. The results show that informants are motivated by better food access, increases in knowledge, financial savings, and independence.

Childhood Experiences and Sporting Event Visitors' Preference for Unhealthy versus Healthy Foods: Priming the Route to Obesity?

To date, there is little knowledge about how experiences in childhood frame adults' food and drink consumption patterns in the context of attending sporting events as spectators. Therefore, the goal of this study was to explore the childhood memories of adults when they visited sporting events and find out whether and why this particular setting makes individuals indulge in unhealthy food. The study comprises two components: Study 1 and Study 2.

Quality of life of residents living in a city hosting mega-sport events: a longitudinal study.

Background: It remains unknown whether and when the hosting of mega-sport events increases quality of life of host city residents. The aim of this study is to assess the changes in quality of life of host city residents over the course of hosting a mega-sport event until three months after the event, depending on residents' perception of the atmosphere during the event.

Methods: The study was conducted in Rio de Janeiro, one of the host cities of the 2014 FIFA World Cup in soccer.

The Color Red Supports Avoidance Reactions to Unhealthy Food.

Empirical evidence suggests that the color red acts like an implicit avoidance cue in food contexts. Thus specific colors seem to guide the implicit evaluation of food items. We built upon this research by investigating the implicit meaning of color (red vs.

Guiding healthier food choice: systematic comparison of four front-of-pack labelling systems and their effect on judgements of product healthiness.

Different front-of-pack (FOP) labelling systems have been developed in Europe by industry and organisations concerned with health promotion. A study (n 2068) was performed to establish the extent to which inclusion of the most prevalent FOP systems--guideline daily amounts (GDA), traffic lights (TL), GDA+TL hybrid (HYB) and health logos (HL)--impact consumer perceptions of healthiness over and above the provision of a FOP basic label (BL) containing numerical nutritional information alone. The design included within- and between-subjects factors.

Labeling exercise fat-burning increases post-exercise food consumption in self-imposed exercisers.

The goal of the study was to determine whether the label given to an exercise bout affects immediate post-exercise food intake. The authors hypothesized that explicitly labeling an exercise bout 'fat-burning' (vs. labeling an exercise bout 'endurance' exercise) would increase post-exercise food intake in individuals who self-impose physical activity, because they are more likely to see the label as signal of activated fat metabolism and license to reward oneself.

Behavioural effects of directive cues on front-of-package nutrition information: the combination matters!

Objective: Nutrition information aims to reduce information asymmetries between manufacturers and consumers. To date, however, it remains unclear how nutrition information that is shown on the front of the packaging should be designed in order to increase both visual attention and the tendency to make healthful food choices. The present study aimed to address this gap in research.

Effects of nutrition label format and product assortment on the healthfulness of food choice.

This study aims to find out whether front-of-pack nutrition label formats influence the healthfulness of consumers' food choices and important predictors of healthful choices, depending on the size of the choice set that is made available to consumers. The predictors explored were health motivation and perceived capability of making healthful choices. One thousand German and Polish consumers participated in the study that manipulated the format of nutrition labels.

Eat fit. Get big? How fitness cues influence food consumption volumes.

Fitness cues on food packages are a common marketing practice in the food sector. This study aims to find out whether and how fitness cues influence food consumption. The results of two field studies show that, even though eating fitness-cued food does not help consumers become more fit, the claims on the packaging increase both serving size and actual food consumption.
