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.

Relationship between Moral Elevation and Prosocial Behavior among College Students: The Mediating Role of Perceived Social Support and Moderating Role of Moral Identity

Objectives:The present study examined the relationship between college students’moral elevation and prosocial behavior.As well as the mediating role of perceived social support and the moderating role of moral identity.Methods:A sample of 489 college students were recruited for the study.They were asked to complete a series of questionnaires,including Moral Elevation Scale(MES),Perceived Social Support Scale(PSSS),Moral Identity Scale(MIS)and Prosocial Tendency Measure(PTM).As part of the data analysis,we used correlation analysis and the method of constructing latent variable structural equation model to explore the mechanism of action among variables.Results:After controlling for gender,discipline,the research found that:(1)Moral elevation positively predicted the prosocial behavior among the college students;(2)Perceived social support mediated the relationship between moral elevation and prosocial behavior;(3)Moral identity moderated the second half of the model(i.e.,the link between perceived social support and prosocial behavior).Specifically,the mediating effect of perceived social support was stronger for college students with high-level moral identity compared to those with low-level moral identity.Conclusions:Moral identity significantly moderates the mediating effect of perceived social support,and the mediating model with moderated is established.

Investigating College Students’ Diet and Physical Activity Behaviors Regarding Non-Communicable Diseases Prevention in China

We aimed to investigate if college students’ dietary and physical activity adhered to the Chinese Dietary Guidelines, the Composing Editorial Board of Physical Activity Guidelines, and WHO recommendation for NCDs prevention. Methods: A 3-day (2 weekdays and 1 weekend day) 24-hour (24-HRs) dietary recall was conducted to record details of participants’ food consumption. One-way analysis of variance (ANOVA) was applied to examine the influence of the identified demographic variables (including BMI, gender, major, family monthly income, and place of household registration) on the 8 food groups’ consumption. We analyzed the effect of the various demographic variables on sodium intake by the student’s t-test. The questionnaire, International Physical Activity Questionnaire (IPAQ)-Short Form, was utilized to assess participants’ physical activity (PA) level. The Wilcoxon-Mann-Whitney was applied to analyze participants’ physical activity. Results: Our research indicated participants consumed much fewer fruits and vegetables and excessive meats on average for both males and females regarding NCDs prevention. Conclusion: Participants’ dietary intake did not comply with the Chinese Dietary Guide-lines recommendation for chronic diseases prevention. Nutrition knowledge and health education are needed for college students. .

Correlation and pathways of behavioral activation systems mediating physical activity level and depressive symptoms among college students

BACKGROUND Depression is a common mental disorder among college students.The main symptoms include being persistent low mood,sad emotional experiences,lack of pleasure,listlessness,and impaired cognitive function accompanied by tendencies of self-harm and suicide.AIM To clarify the pathways and effects of the behavioral activation system between physical activity and depressive symptoms in college students with depressive symptoms.METHODS This cross-sectional research screened 3047 college students.Of these,472 had depressive symptoms,with a depression detection rate of 15.49%.Furthermore,442 college students with depressive symptoms were analyzed.A one-way analysis of variance and Pearson’s correlation,linear regression,and structural equation modeling analyses were used to explore the correlations and pathways of the interactions between the variables.RESULTS Depressive symptoms were significantly negatively correlated with physical activity(r=-0.175,P<0.001),the behavioral activation system(r=-0.197,P<0.001),and drive(r=-0.113,P=0.017).Furthermore,it was negatively correlated with fun-seeking(FS)(r=-0.055,P=0.251);however,it was not significant.Physical activity was significantly positively correlated with reward responsiveness(RR)(r=0.141,P=0.003)and drive(r=0.124,P=0.009)and not significantly positively correlated with FS(r=0.090,P=0.058).The mediating effect of RR between physical activity and depressive symptoms was significant[B=-0.025,95%confidence interval(95%CI):-0.051 to-0.008,P=0.001].The direct and total effects of physical activity on depressive symptoms and were significant(B=-0.150,95%CI:-0.233 to-0.073,P<0.001;B=-0.175,95%CI:-0.260 to-0.099,P<0.001),respectively.CONCLUSION As physical activity levels increased,depression scores among college students decreased.The mediating effect of RR between physical activity and depressive symptoms was significant.Therefore,colleges and universities should encourage college students with depression to increase their physical activity and improve their behavioral activation system.Particular attention should be paid to RR,which may reduce the prevalence of depressive symptoms.

HIV/AIDS related perception and behavior: A comparative study among college students of different majors in China

Objective:In order to carry out proper education and intervention of AIDS based on different features and demands of different majors,this study aimed to compare the difference of college students from six majors in China in the aspects of AIDS-related knowledge,attitudes and behaviors.Methods:A questionnaire survey was carried out among 18,644 students in 30 colleges/universities from 9 provinces of China,who were recruited through stratified cluster sampling.AIDS-related knowledge,attitude,condom-use intention,self-efficacy and sexual behavior of these students were investigated.Results:AIDS-related knowledge level of students majoring in education was the lowest while that of medical students was the highest as well as highest self-efficacy of condom use.Students of music or fine arts had the strongest intention to use condoms,while the students majoring in education had the weakest.The sexually active percentages of male students from different majors ranked as follows:music or fine arts(29.5%),minority nationality(12.2%),science&tech(10.9%),medicine(10.6%),educationmajor(10.0%),and liberal arts(8.2%).Among female students,the rank was music or fine arts(11.0%),science&tech(6.2%),education-major school(4.5%),minority nationality(4.5%),liberal arts(4.1%),and medicine(2.8%).Conclusion:It is urgent to enhance proper AIDS-related education and intervention based on the features and demands of students from different majors or universities,for example,to enhance comprehensive AIDS prevention education among students major in education and to increase behavioral skills to prevent sexually transmitted diseases among students from colleges or faculty of music or fine arts.

A Survey on the Sexual and Contraceptive Behaviors in Chinese Female College Students

To get information in the sexual and contraceptive behaviors in Chinese female college students, a randomized cluster sampling was conducted in colleges and universities in Wuhan Area, China, in terms of types of colleges, subjects （literature, sciences, medicines, art etc）, and grades etc. A total number of 2450 questionnaires were distributed, with 2365 questionnaires returned being valid. The return rate of valid questionnaires was 96.6 %. The questionnaire investigation was conducted on a multiple-choice and anonymous basis. Data were input into computer and SPSS12.0 software package was employed for statistical analysis. Among the female students, 1196 had the experiences of hugging and kissing （50.57 %） and 423 （17.89 %） had sexual experiences （sexual intercourse）. The first sexual intercourse took place at the age of 19.23±1.74 y. There were significant differences in the sexual experiences among the majors of different subjects, with the rate of sexual experiences in art majors （43.17 %） and high-grade students （34.31%） being the highest. The causes of the first sexual intercourse included sexual impulse, curiosity, intention to strengthen the relationship or to show loyalty to boyfriend and sometimes violence. While the motives of the sexual intercourse within the past one year before the investigation were to satisfy the sexual needs and to strengthen the relation with their boyfriends. With both first intercourse and sexual experiences within last one year, the partners of the sexual intercourse were mainly their boyfriends （95.7 % and 97.3 % respectively）, but the partners also included acquaintances, ＂one night stand＂ partners and customers of sex trade. Some of them had multiple sexual partners, with the highest number of the sexual partners being 11. In the first sexual intercourse of the subjects, 44.0 % of them did not take any contraceptive measures; only 16.4 % of them used condoms. In the sexual intercourse within the last one year, only 44.6 % took contraceptive measures every time they had sexual intercourse. Among those who took contraceptive measures, 64.4 % used condoms. Among those who had sexual intercourse, 101 persons got pregnant, with a rate of pregnancy being 4.3 %, accounting for 23.9 % of all who had sexual intercourse. Among those who got pregnant, 78 persons got pregnant once; the others became pregnant more than two times, the highest being 5 times. There were 122 persons who had inflammation of reproductive system, mostly vaginitis. Other conditions included venereal warts and herpes genitalis. It is concluded that the rate of sexual behaviors is high in female college students and there exist promiscuity, unexpected pregnancy and transmission of STD in the students.

Problem Drinking Behaviors: Differential Effects of Stress and School Type on College Students

Given that alcohol use is highly prevalent at US colleges, we explored factors related to problem drinking behaviors (PDB;binge drinking, driving after drinking, sexual intercourse after drinking) among 4098 Black and White students from two- and four-year colleges who completed an online survey. We found an interaction between race and sex such that, among Whites, females had less PDB than males (B = 0.09, CI: 0.05;0.40, p = 0.01). An interaction between race and school type also existed, such that White students from four-year schools had greater PDB (B = 0.11, CI: 0.20;0.54, p < 0.001). An interaction between race and stress suggested that Black students were more negatively affected by stress in terms of PBD (B = 0.12, CI: 0.01;0.07, p = 0.01).

Cognitive Behavioral Therapy as the Basis for Preventive Intervention in a Sleep Health Program: A Quasi-Experimental Study of E-Mail Newsletters to College Students

Several reports suggest that college students often have atypical sleep patterns and experience poor sleep quality. We examined the effect of a cognitive behavioral therapy (CBT) based intervention program to improve sleep quality and overall mental health among college students. The intervention was delivered in the form of e-mail newsletters. Fifty-three students participated in the intervention group, and another 50 students participated in the control group. The intervention group received a lecture on sleep hygiene;once-weekly e-mail newsletters on sleep health topics (sleep hygiene, stimulus control, sleep restriction, sleep titration, and relapse prevention) and were asked to maintain a four-week sleep diary. The Pittsburgh Sleep Quality Index (PSQI), a measure of sleep quality, and the Kessler 6, a measure of psychological distress, were administered before the lecture (as the baseline measurement) and again 16 weeks later (follow-up measurement). PSQI and K6 scores were reduced in the intervention group compared with the control group. A CBT-based sleep health program utilizing e-mail newsletters may work to improve sleep quality and mental health. This program may represent a cost effective way for Japanese students to receive treatment for poor sleep and may also serve to prevent psychiatric problems.

Investigation and analysis of 14034 college students on COVID-19 and its countermeasures and suggestions

Objective:To understand the current situation of college students'knowledge,cognitive attitude and behavior(KAP)towards the prevention and control of Corona Virus Disease 2019(Corona Virus Disease 2019,COVID-19)during the epidemic,so as to provide theoretical basis for college students'resumption of study and campus prevention and control.Methods:A questionnaire survey was conducted among 16,410 college students by using the convenient sampling method of,One-Way ANOVA and Logistic regression analysis of the survey data.Results:The total awareness rate of college students on COVID-19 was 85%,the average knowledge score was(70.4±10.0),and the proportion of high cognition was 74.5%.The average attitude score of college students was(3.78±0.55),and only 3.9%of them held a positive attitude.The average score of college students'protective behaviors was(19.35±1.69),and 48.8%of them took good protective behaviors.Binary logistic regression analysis showed that the proportion of students with high cognition who adopt good protective behaviors is higher than that of students with low cognition(95%CI:0.621-0.752).The proportion of students with a positive attitude to adopt good behaviors was higher than that with a negative attitude(95%CI:1.398-2.009),Spearman rank correlation analysis results showed that there was a weak positive correlation between cognition and attitude(r=0.056,P<0.05),and a weak positive correlation between cognition and behavior(r=0.118,P<0.05),and a weak positive correlation between attitude and behavior(r=0.038,P<0.05).Conclusion:College students have a good overall cognition of COVID-19,but their attitudes and protective behaviors need to be further improved.Therefore,knowledge education,behavioral intervention and psychological counseling on COVID-19 epidemic prevention and control among college students should be strengthened to improve their prevention and control ability and physical quality.

The effects of prolonged sitting behavior on resting-state brain functional connectivity in college students post-COVID-19 rehabilitation:A study based on fNIRS technology

Functional near-infrared spectroscopy(fNIRS)was used to explore the effects of sedentary behavior on the brain functional connectivity characteristics of college students in the resting state after recovering from Corona Virus Disease 2019(COVID-19).Twenty-two college students with sedentary behavior and 22 college students with sedentary behavior and maintenance of exercise habits were included in the analysis;moreover,8 min fNIRS resting-state data were collected.Based on the concentrations of oxyhemoglobin(HbO2)and deoxyhemoglobin(HbR)in the time series,the resting-state functional connection strength of the two groups of subjects,including the prefrontal cortex(PFC)and the lower limb supplementary motor area(LS),as well as the functional activity and functional connections of the primary motor cortex(M1)were calculated.The following findings were demonstrated.(1)Functional connection analysis based on HbO2 demonstrated that in the comparison of the mean functional connection strength of homologous regions of interest(ROIs)between the sedentary group and the exercise group,there was no significant difference in the mean functional strength of the ROIs between the two groups(p>0:05).In the comparison of the mean functional connection strengths of the two groups of heterologous ROIs,the functional connection strengths of the right PFC and the right LS(p?0:0097),the left LS(p?0:0127),and the right M1(p?0:0305)in the sedentary group were significantly greater.The functional connection strength between the left PFC and the right LS(p?0:0312)and the left LS(p?0:0370)was significantly greater.Additionally,the functional connection strength between the right LS and the right M1(p?0:0370)and the left LS(p?0:0438)was significantly greater.(2)Functional connection analysis based on HbR demonstrated that there was no significant difference in functional connection strength between the sedentary group and the exercise group(p>0:05)or between the sedentary group and the exercise group(p>0:05).Similarly,there was no significant difference in the mean functional connection strength of the homologous and heterologous ROIs of the two groups.Additionally,there was no significant difference in the mean ROIs functional strength between the two groups(p>0:05).Experimental results and graphical analysis based on functional connectivity indicate that in this experiment,college student participants who exhibited sedentary behaviors showed an increase in fNIRS signals.Increase in fNIRS signals among college students exhibiting sedentary behaviors may be linked to their status post-SARS-CoV-2 infection and the sedentary context,potentially contributing to the strengthened functional connectivity in the resting-state cortical brain network.Conversely,the fNIRS signals decreased for the participants with exercise behaviors,who maintained reasonable exercise routines under the same conditions as their sedentary counterparts.The results may suggest that exercise behaviors have the potential to mitigate and reduce the impacts of sedentary behavior on the resting-state cortical brain network.
