The Impact of Social Media on Dietary Behaviors and Body Image of College Students: A Qualitative Approach

Background: The use of social media platforms for health and nutrition information has become popular among college students. Although social media made information readily accessible in different formats, nutritional misinformation promoted by influencers and non-experts caused negative impact on diet behavior and perception of body image. Previous research indicated that extensive use of social media was positively linked to disordered eating behaviors. Social media platforms like Facebook and Instagram that allow users to follow celebrities intensified exposure to influencers’ messages and images and resulted in negative moods and body dissatisfaction. Objective: This paper aims to explore the impact of social media on college students’ dietary behaviors and body image. Participants: 18 undergraduate students from a public university in the Southern United States were recruited through a mass email. Methods: A cross-sectional qualitative study of three focus groups was conducted. The focus groups were based on guiding open-ended questions. Atlas.ti was used to code and analyze the data using inductive and deductive codes. Results: Three main themes were identified. The conditions theme included elements that explain why and how social media influences the participants’ actions. The actions theme included eating behavior, physical activity, and dietary supplement intake. The consequences theme describes anticipated or actual outcomes of actions such as body image and ideal weight. Conclusions: Social media has had a negative influence on diet behaviors and a positive influence on physical activity. Evidence-based nutrition and weight management information is needed to thwart potential misinformation.

Discrepancy between the Image Held by Nursing Students of Themselves as Employed Nurses during the Pre-Employment Period and the Post-Employment Reality Faced by Novice Nurses

The difference between the expectations of work an individual forms before joining an organization and their perception of work after becoming an organization member is called reality shock and has a significant impact on the reasons why new nurses leave their jobs. To reduce reality shock, it is necessary to clarify the discrepancy between the reality and the image of oneself after employment, which is the source of expectations. However, while there is a large body of literature on reality shock among nurses, no studies have specifically investigated student nurses’ image of post-employment confidence. We conducted semi-structured interviews with eight nursing students who had received job offers and 10 professional nurses up to two years after graduation to clarify the differences between the image that nursing students hold of themselves as employed nurses during the period immediately before employment and the reality that they find after employment. As a result, four core categories (with 25 categories) related to participants’ images of themselves as employed nurses were extracted: life after employment, adaptation to work, adaptation to the workplace, and career foundation-building. Fourteen categories were extracted regarding the reality that nurses found after employment;upon comparing and classifying these categories according to the four core categories, a lack of concreteness in the nursing students’ image of themselves as employed nurses was identified. The results suggest that support measures, both in the basic nursing education program and in clinical hospital practice, to improve the concreteness of the image that nursing students hold of themselves as employed nurses and of nursing work can reduce reality shock and prevent job turnover upon their entry into the workforce.

Relationships between Gender, Weight, and Body Image: Effects on Stress Management and Life Satisfaction in University Students

This study highlights the importance of understanding how gender and weight affect key aspects of well-being, such as body image, stress management, and life satisfaction among college students. By examining these relationships, the study aims to provide information that serves as a basis for designing specific interventions to promote mental health and general well-being in this population. The objective is to provide insights into the relationships between these variables to guide targeted interventions for student well-being. Methods: A total of 100 university students from Chile (60% women, 40% men), aged between 18 and 25, participated in this study. Participants were classified into weight categories based on their Body Mass Index (BMI) according to WHO standards: underweight, normal weight, overweight, and obesity. Validated scales were used to measure body image, stress management, and life satisfaction. Descriptive analyses and one-way ANOVA were conducted to identify significant differences between gender and weight categories. Results: Significant differences were found in stress management and body image according to weight categories. Participants with obesity reported the lowest scores in both body image and stress management, while underweight participants reported the highest scores. Men reported slightly better stress management, but the difference was not statistically significant. A moderate positive correlation was found between body image and life satisfaction (r = 0.29, p Conclusion: Gender and weight play an essential role in influencing body image, stress management, and life satisfaction among university students. These findings highlight the need for interventions that promote a healthy body image and effective stress management strategies, particularly for overweight and obese students.

Attitude survey of nursing students in Madagascar and Japan

Background: Few investigations have focused on nursing students from a developing country in relation to a developed country like Japan. Objective: This study explored differences between the nursing students in Madagascar and Japan. Subjects and Methods: This is a prospective analytical study of 63 nursing students—32 Japanese and 31 Malagasy. Questionnaires were distributed to students in Madagascar and Japan in 2010 and collected for statistical analysis. Results: Malagasy students tended to think that nursing plays a psychological role, and they have positive view for this function. In contrast, Japanese students tended to think that nursing is physical work and they make a point of its outcome and the need for social and economic guarantees. Conclusion: The nursing students in Madagascar and Japan expressed different views and goals. While several factors may be involved in these differences, their distinct medical situations are most likely the major contributor.

Public Diplomacy and Beijing City Image Research From Major International Sporting Events Perspective

This paper focuses on Beijing as the host city for the major international sporting events and its influence on the city image building of Beijing. Major international sporting events are the key channels for the exchange and dissemination of information among athletes from various countries, media coverages, national and international audiences which involves interpersonal communication, organizational communication, and mass communication at all levels. At the same time, the volunteers, especially young volunteers （mostly college student volunteers） considered as the Beijing city spokesperson and also as a group of ＂public diplomacy ambassadors＂, transfer positive energy in international communication during major international sporting events. Therefore, major international sporting events held in Beijing play an irreplaceable role in the image building of the capital city of China, Beijing.
