The Role of Body Image, Disordered Eating and Lifestyle on the Quality of Life in Lithuanian University Students

Body image dissatisfaction is associated with perceived body weight among secondary school adolescents in Harar Town, eastern Ethiopia

Purpose

Body image dissatisfaction has emerged as an important determinant of dietary and physical activity, which in turn determine adolescents' nutritional status. Hence, it is important to understand predictors of body image dissatisfaction. Therefore, this study aimed to assess body image dissatisfaction and its associated factors among secondary school adolescents in the study area.

Methods

Data collected for other purposes were used to assess body image dissatisfaction among adolescents in Harar town. Body image dissatisfaction was assessed using the Body Part Satisfaction Scale. Data processing and analysis were performed using STATA version 14, and binary logistic regression was used to identify factors associated with body image dissatisfaction. Factors associated with body image dissatisfaction were determined by estimating AOR along with 95% CI and the statistical significance was declared at a p-value less than or equal to 0.05.

Result

The prevalence of body image dissatisfaction was 22.06% [95% CI (19.63, 24.70)]. This study also revealed that males were more dissatisfied with their upper torso and face, and females were more dissatisfied with their middle torso, lower torso, height, and weight than males. In this study, body image dissatisfaction was associated with perception of being fat [AOR = 1.89, 95% CI (1.23, 2.91)], anxiety [AOR = 1.59, 95% CI (1.02, 2.48)], and cigarette smoking [AOR = 1.63, 95% CI (1.03, 2.58)].

Conclusion

Almost one in five secondary school adolescents in Harar had body image dissatisfaction, which was significantly associated with perceptions of being fat, anxiety, and smoking. In this study, a significant number of the adolescents experienced body image dissatisfaction. Hence, all concerned bodies have to take action to reduce the burden.

Longitudinal associations between adolescent skin color satisfaction and adult health outcomes in Black women

OBJECTIVE

Although emerging studies examine the inverse relationship between body satisfaction and disordered eating for Black women, it has not been established how racially salient aspects of body satisfaction may have implications for eating behaviors and longitudinal health outcomes.

METHOD

In a longitudinal sample of 455 Black women, we examined whether skin color satisfaction across ages 10-15 was directly related to adult health outcomes at age 40 (e.g., disordered eating, self-esteem, self-reported health, depressive symptoms, and cardiovascular risk). We also investigated the indirect impact of skin color satisfaction on adult health, mediated by body satisfaction, and binge eating.

RESULTS

No significant direct or indirect effects of adolescent skin color satisfaction were observed for depressive symptoms or cardiovascular health outcomes. At ages 10 and 12, skin color satisfaction had negative and positive direct effects, respectively, on self-esteem. At age 15, greater skin color satisfaction was directly associated with greater self-reported health. Post hoc analyses revealed that when additionally accounting for adolescent body satisfaction, greater skin color satisfaction was indirectly associated with greater self-esteem and self-reported health, alongside lower cardiovascular risk.

CONCLUSIONS

Although previous research suggests that in adolescence, Black girls' skin color satisfaction affects both body satisfaction and disordered eating behaviors, this association does not hold into midlife. Rather, post hoc analyses suggest that the lasting effects of adolescent skin color satisfaction are mediated by the longitudinal stability of body satisfaction, which in turn, is associated with adult health outcomes.

The Role of Self-Compassion and Attributions in the Mental Health of Older Adolescents amid the COVID-19 Pandemic

This study aimed to examine the relationship among self-compassion, attributional styles, and mental health and their components in older adolescents in the context of the COVID-19 pandemic. The role of each component of self-compassion (self-kindness, common humanity, mindfulness, self-judgment, isolation, and over-identification) and attributions (globality, stability, self-worth, and negative consequences) in predicting mental health was also analyzed. There were 322 participants aged 18 to 22 that participated in an online survey. The participants filled out a form that consisted of sociodemographic questions, COVID-19-related questions, the Self-Compassion Scale, the Mental Health Continuum-short form-and the Cognitive Styles Questionnaire-very short form. The results indicated moderate levels of self-compassion, attributions, and mental health in participants. Furthermore, gender differences in self-compassion were confirmed, meaning that male participants had higher total levels of self-compassion, and certain differences were observed on attribution subscales, but not on well-being subscales. Self-compassion and mental health were found to be positively correlated with each other and negatively correlated with negative attributions. Of the four attributional components, stability and negative consequences were revealed to be significant negative predictors in the first step but lost their significance with the inclusion of self-compassion components in the second step of the analysis. Regarding the six components of self-compassion, self-kindness, recoded isolation, and common humanity were significant positive predictors in the second step of the analysis. COVID-19-related items did not show any significant intergroup differences. Our findings contribute to a better understanding of the relationship between positive mental health, self-compassion, and attributions in older adolescents so that they can be used as theoretical support for related interventions, especially during and after times of crisis, such as a pandemic.

Differences in Perceptual and Attitudinal Body Image Between White and African-American Adults Matched for Sex, Age, and Body Composition

PURPOSE

The purpose of this study was to evaluate the differences in perceptual and attitudinal body image between White and African-American males and females matched for sex, age, BMI, and other body composition components using a combination of 3-dimensional mobile digital imaging analysis (DIA) and the Multidimensional Body-Self Relations Questionnaire-Appearance Scale (MBSRQ-AS).

METHODS

One-hundred non-Hispanic White (n=50) and non-Hispanic African-American (n=50) adults (M=34, F=66) matched for sex, age, BMI, and body composition components completed this cross-sectional study. Participants underwent several anthropometric assessments, completed the MBSRQ-AS, and rated their perceived appearance, ideal appearance, and the appearance they believed a partner would find societally attractive using a state of the art mobile 3-dimensional DIA produced using broad developmental populations. Body image distortion was measured as the perceived minus actual appearance, and body image dissatisfaction was defined as the ideal appearance and appearance a partner would find attractive minus the perceived appearance.

RESULTS

Using the DIA, only African-American females demonstrated significant body image distortion (p<0.001); reporting perceived appearances significantly lower their than their actual. Further, AA females demonstrated significantly larger differences between their ideal and perceived appearance (p=0.009), perceived larger bodies as more attractive to a potential partner (p=0.009), and reported higher ratings of appearance evaluation (p=0.001) and body area satisfaction (p=0.011) compared to White females.

CONCLUSIONS

After accounting for all anthropometric determinants of body image, perceptual and attitudinal body image differs between White and African-American adults with differences supporting larger body size acceptance for African-American individuals, particularly African-American females.

The Comparison of Disordered Eating, Body Image, Sociocultural and Coach-Related Pressures in Athletes across Age Groups and Groups of Different Weight Sensitivity in Sports

The aim of the present study was to compare disordered eating (DE), body image, and sociocultural and coach-related pressures between athletes of different age groups (adolescents and adults) and between athletes participating in weight-sensitive (WS) and less WS groups. A total of 1003 athletes participated in this study. The age range of the sample was 15 to 44 years, and the mean age was 18.9 ± 5.8 years (51.3% were female). Athletes who voluntarily agreed to participate in the study were provided with the study measures on DE, body image and sociocultural attitudes towards appearance. Vomiting, laxative misuse and excessive exercise were more prevalent in adolescent female athletes than adults, while dietary restraint was more common in adult male athletes than adolescents. Adolescent female athletes experienced higher sociocultural (family, peers) and sport-related (coach) pressures and a less positive body image compared with adult female athletes. Adult male athletes experienced higher overweight preoccupation, more DE and unhealthy eating habits, and engaged in more frequent self-weighing behaviour compared with adolescent males. When the effect of weight sensitivity in sports was tested, a higher prevalence of DE and overweight preoccupation, more frequent self-weighing, and higher body-image-related pressure from coaches were observed in female athletes participating in aesthetic weight-sensitive (WS) sports as compared with those participating in less WS sports. No differences in positive body image were observed in female WS and less WS sports. Special DE prevention and positive body image promotion programs are necessary for female competitive athletes and parents of adolescent female athletes, especially those participating in aesthetic ones. For adult male athletes, special programs aiming to promote healthy eating should be implemented to prevent DE and body image concerns. Special education about DE prevention is compulsory for coaches who train female athletes.

Disordered Eating Attitudes and Food Choice Motives Among Individuals Who Follow a Vegan Diet in Brazil

Importance

It remains controversial whether adhering to a vegan diet may be associated with a higher prevalence of disordered eating. Also, main food choice motives and their association with disordered eating in this population are still unknown.

Objective

To determine the association between disordered eating attitudes and food choice motives of individuals who follow a vegan diet.

Design, Setting, and Participants

This is a cross-sectional online survey conducted between September 2021 and January 2023. Individuals of both sexes, aged 18 years or older, following a vegan diet for at least 6 months, currently living in Brazil were recruited through advertisements on social media.

Exposure

Adherence to a vegan diet and food choice motives.

Main Outcomes and Measures

Disordered eating attitudes and food choice motives.

Results

Nine hundred seventy-one participants completed the online survey. Median (IQR) age and BMI of participants was 29 (24-36) years and 22.6 (20.3-24.9), respectively, and 800 participants (82.4%) were female. Most participants (908 respondents [94%]) were categorized with the lowest level of disturbed eating attitudes. "Need and hunger," "liking," "health," "habits," and "natural concerns" were the most important food choice motives in this population, while "affect regulation," "social norms," and "social image" were the less important ones. Adjusted models showed that "liking," "need and hunger," and "health" were associated with lower levels of disordered eating attitudes, while "price," "pleasure," "sociability," "traditional eating," "visual appeal," "social norms," "social image," "weight control," and "affect regulation" were associated with higher levels of disordered eating attitudes.

Conclusions and Relevance

In this cross-sectional study, as opposed to previous suggestions, levels of disordered eating were very low among vegans, although certain food choice motives were associated with disordered eating attitudes. Understanding the motivations of adhering to diets that may impose restrictions, which include vegan diets, may help tailor interventions focused on promoting healthy eating and preventing or treating disordered eating.

The mediating effect of body appreciation between muscle dysmorphia and bulimia nervosa among Lebanese adolescents

BACKGROUND

Muscle dysmorphia (MD) is a common psychological disorder present in Lebanese adolescents. Several disorders can be present concomitantly with MD such as bulimia nervosa and exercise addiction. This study aims to explore the mediating effect of body appreciation between Muscle dysmorphia and bulimia nervosa, and to validate the exercise addiction inventory scale in Lebanese adolescents.

METHODS

This was a cross-sectional designed study, conducted between August-September 2022, and enrolling 403 adolescents currently residing in Lebanon (15 to 18 years old), from all Lebanese governorates (Beirut, Mount Lebanon, North, South, and Bekaa). Our sample was chosen using the snowball technique, a soft copy of the questionnaire was created using google forms software, and an online approach was conceived to proceed with the data collection.

RESULTS

The mean age of the participants was 16.63 ± 1.46 years with 57.3% females. The factor analysis for the Exercise Addiction Inventory suggested one factor, which explained 62.58% of the common variance. The confirmatory factor analysis revealed an adequate fit to the model with satisfactory Maximum Likelihood Chi-Square/Degrees of Freedom (χ²/df), SRMR, CFI, TLI, and AVE. The mediation analysis showed that the direct relation between bulimia and MD was not significant after eliminating the effect of body appreciation (r = .12, p < .001). However, body appreciation was significantly associated with bulimia nervosa (r=-1.06, p < .001) and MD (r=-.28, p < .001).

CONCLUSION

Body appreciation was found to be a mediator between muscle dysmorphia and bulimia nervosa and thus it is the main factor leading to both disorders. Therefore, body appreciation should be addressed in the evaluation and management of Muscle Dysmorphia.

Sociodemographic Characteristics, Dietary Intake, and Body Image Dissatisfaction Among Saudi Adolescent Girls

This study assesses sociodemographic characteristics, dietary intake and body image dissatisfaction (BID) among Saudi adolescent girls. A total of 399 girls ages 13-14 were randomly selected from intermediate schools in Arar, Saudi Arabia. Data on anthropometric measurements, sociodemographic characteristics, dietary intake and body image (BI) were collected. Multiple linear regression was used to predict the association between variables. Most adolescents had a normal weight based on their body mass index (BMI), normal waist circumference (WC), and normal waist-to-height ratio (WHtR). Fried chicken and Kabsa rice were the most frequently consumed foods; most girls consumed excessive fat. Most girls had BID (81.5%), and 51.4% desired to lose weight. BMI was positively correlated with age and current BI (p<0.001) and negatively associated with dairy product intake (p=0.004) and desired BI (p<0.001). WC had a positive association with age (p=0.001) and current BI (p<0.001) and a negative association with dairy product intake, cereal and grain intake (p=0.001) and ideal BI (p<0.001). WHtR was positively associated with current BI (p<0.001) and negatively associated with cereal and grain intake (p=0.005), dairy product intake and desired BI (p<0.001). Although most participants had a normal weight, they consumed excessive fat and were dissatisfied with their BI, which are significant predictors of obesity. Saudi adolescent girls require nutritional interventions to help them transition to a healthy diet, positive BI and healthy lifestyle.

Association between lifestyle behaviors and health-related quality of life among primary health care physicians in China: A cross-sectional study

Background

Primary health care (PHC) serves as the gatekeeper of health system and PHC physicians take on significant obligations to provide health care services in the pursuit of Universal Health Coverage (UHC). PHC physicians' health-related quality of life (HRQoL) can have a strong impact on patients, physicians and the health care system. Lifestyle interventions are found to be effective to improve HRQoL. The purpose of this study was to evaluate the association between lifestyle behaviors and HRQoL among PHC physicians, so that lifestyle intervention can be tailored by policy makers for health promotion.

Methods

A survey covering 31 provinces and administrative regions in China was conducted in 2020 using a stratified sampling strategy. Data on sociodemographic characteristics lifestyle behaviors and HRQoL were collected by a self-administered questionnaire. HRQoL was measured through EuroQol-five dimension-five level (EQ-5D-5L) instrument. A Tobit regression model was performed to evaluate the association between sociodemographic characteristics, lifestyle behaviors and HRQoL.

Results

Among 894 PHC physicians who completed the survey, Anxiety/Depression (AD) was the dimension with the most problems reported (18.1%). Regular daily routine (β = 0.025, 95%CI 0.004 to 0.045) and good sleep quality (β = 0.049, 95% CI = 0.029 to 0.069) were protective factors for HRQoL, while smoking (β = −0.027, 95% CI = −0.079 to −0.003) and frequency of eating breakfast (β = −0.041, 95%CI = −0.079 to −0.003) were negatively associated with HRQoL. Physical activity and alcohol drinking were not significantly associated with HRQoL.

Conclusion

These findings suggest that tailored interventions on daily routine, improving sleep quality, and tobacco control among PHC physicians may be effective strategies to improve their HRQoL.

The relationship between body image and quality of life in postmenopausal women: A correlational cross-sectional study

The relationship between body image (BI) and quality of life (QoL) among postmenopausal women was assessed in this study. This correlational cross-sectional study was conducted on 320 postmenopausal women in Tehran-Iran. The subjects were selected using a multistage sampling method. Data was collected using the WHOQOL-BREF questionnaire, the Fisher's body image questionnaire, and a socio-demographic questionnaire. Total score and score of all domains of QoL had a significant positive correlation with total score and score of all dimensions of BI and BI was a predictor of QoL (p < 0.001). Therefore, women health policies should concentrate on BI improvement for promoting QoL during menopause.

Associations between Self-Objectification and Lifestyle Habits in a Large Sample of Adolescents

The aim of the present study was to test associations between self-objectification and health-related lifestyle habits in a large sample of adolescents. In 2019–2020, a large sample of adolescents (n = 1402, 40.4% boys) participated in the survey and, as a part of a larger study, filled in questionnaires on self-objectification and lifestyle. Self-objectification was assessed using the Self-Objectification Questionnaire (SOQ). The lifestyle questionnaire had three batteries: eating attitudes and behaviors, dietary habits, and questions on harmful behaviors together with time spending patterns: sedentary lifestyle and physical activity. The ages ranged from 15–19 years with a mean age of 16.97 ± 0.46 years. Self-objectification (SO) was associated with a less healthy lifestyle: more frequent dieting and unhealthy eating habits in girls, skipping breakfast, and a lower number of meals per day. Adolescent boys and girls with higher SO demonstrated more frequent smoking and alcohol consumption until they felt dizzy and more frequent consumption of soft drinks, energy drinks, and fast foods. Girls with higher SO demonstrated lower perceived physical activity and longer duration of internet browsing for non-educational purposes. The results of the present study inform healthy lifestyle promotion programs for adolescents, suggesting that including psychoeducation about self-objectification, body functionality, and positive embodiment might be an effective strategy.

Effect of an education and mindfulness-based physical activity intervention for the promotion of positive body image in Lithuanian female students

PURPOSE

The aim of this study was to test the effectiveness of an 8-week classroom education and mindfulness-based physical activity intervention for the promotion of positive body image in female students.

METHODS

A quasi-experimental study was carried out with 110 Lithuanian female students (mean age 21.5 ± 3.5, range 19-35 years). Thirty students voluntarily participated in the intervention programme and 80 students volunteered in the assessment-only control group. The intervention comprised five cognitive behavioural therapy classroom education sessions and mindfulness-based exercise (one exercise workout per week). The intervention group was evaluated with a pre-test and post-test and the control group completed measures at parallel times.

RESULTS

Compared with the control group participants, the intervention group participants reported greater improvements in positive body image and a reduction in body dissatisfaction and drive for thinness and internalisation of stereotyped beauty ideals, with medium to large effects. There were significant time × group interactions for pre-test to post-test changes in internalisation of beauty ideals, body area satisfaction, body dissatisfaction and body appreciation. In all cases, the interaction reflected greater pre-test to post-test changes in the intervention group compared with the control group, whose scores remained stable. A decrease in appearance orientation, overweight preoccupation, disordered eating and physical activity was observed in the control group, but the effect sizes were low.

CONCLUSION

The preliminary findings of this study support the efficacy of cognitive behavioural therapy methods and mindfulness-based exercise intervention aimed to promote positive body image in student-aged women. Future studies should test the efficacy of the introduced programme in larger randomised samples of young women.

An exploration of the tripartite influence model of body image in Lithuanian sample of young adults: does body weight make a difference?

PURPOSE

The present study aimed to test the sociocultural Tripartite Influence Model (TIM) that helps to explain the associations between the sociocultural pressures to achieve stereotyped body ideals and disordered eating in young Lithuanian women and men of different body mass.

METHODS

A mixed-gender sample of students (n = 1850, 58.8% female, the mean age of men was 20.4 (SD = 3.1) years, of women 22.4 (SD = 5.8) years) filled in series of questionnaires including the social attitudes towards appearance, body image, disordered eating and drive for muscularity. Mediation analyses were performed to estimate the size of total, direct, and indirect effects of variables in the models.

RESULTS

For women of different body weight, the TIM model was fully replicated. For men of normal weight, internalization of the muscular/athletic ideal, drive for muscularity and greater investment towards appearance mediated the relationships between peers' pressures and disordered eating. For overweight men, internalization of the thin and muscular/athletic ideals, poorer body image mediated associations between pressure from the peers and disordered eating. However, the internalization of the muscular/athletic ideal and the greater appearance evaluation mediated the associations between sociocultural pressures and disordered eating for overweight and obese men.

CONCLUSION

The TIM was replicated in women of different body weight. However, internalization of the thin/low fat ideal was not relevant for men of normal body weight and internalization of the muscular ideal had different outcomes for men of different body mass index. The implications of the results for practice are discussed.

Gender Differences in Healthy Lifestyle, Body Consciousness, and the Use of Social Networks among Medical Students

Background and Objectives: The goal of this survey was to identify the relationship between the level of satisfaction with body image, perceived health, and the usage of social media among freshmen medical university students. The influence of social media and peers was also related to body image. Materials and Methods: An online survey was distributed among freshmen healthcare students. The questionnaire collected sociodemographic, anthropometric data, and information about students’ perception about healthy lifestyle using open-ended questions, as well as their opinion about the importance of perfect body image and the level of satisfaction with their physical appearance. Questions focusing on the use of social media and the relationship with body image collected data on the use of social networks and how they affect students’ opinion about their own body image. Psychometric data were also gathered using the Body Consciousness Scale. For the statistical analysis, QSR NUD*IST (Non-numerical Unstructured Data Indexing Searching and Theorizing) Vivo 12 was used for qualitative data and IBM Statistical Package for Social Sciences (SPSS) Statistics for Windows, version 23 (SPSS Inc., Chicago, IL, USA) was used for descriptive and comparative results. Results: In total, 77 students aged 20.09 ± 2.47 years, of which the majority were women (75.30%), were included in the survey. The use of social network was about 4.81 ± 3.60 h/day. Facebook was the most used social networking site (94.80%), followed by Instagram (92.20%), Snapchat (16.90%), WhatsApp (15.60%), and TikTok (10.40%). The most common reason for using these sites was socialization. We found that 64.90% of healthcare students were normal weight. The main barriers for having a healthy lifestyle, as they were perceived by students, were the busy schedule and the lack of time needed to prepare healthy meals, lack of motivation, and lack of money. Women scored higher for the Private Body Consciousness and Public Body Consciousness scales. The main aspects related to a healthy lifestyle referred to physical activity, consumption of fruit and vegetables, water consumption, and a good quality of sleep. Gender differences were discussed as well. Conclusions: The results illustrated the complexity of the relationship between social media and body image and the need to prevent body image concerns, especially in young women.

The Role of Plant-Based Protein Functional Food in Preventing Acute Respiratory Disease: A Case Study

The Kaliningrad region is known for its specific climate, which can negatively affect the adaptive potential of the body. This manifests in an increased incidence of respiratory diseases and skin conditions. To prevent high morbidity, a plant protein product was included in the diet of first-year university students. This study aimed to assess the effectiveness of this food intervention in preventing the most common diseases among Kaliningrad students. Two groups of university students took part in the food trial. In the control group, catabolic processes prevailed in nutrient metabolism. Disadaptation manifested itself in the metabolism of proteins, vitamins, minerals, hematopoiesis and humoral immunity. Inflammation was indicated by α1- and α2-globulins, a weak immune response, and IgM and IgG. High oxidative stress and low antioxidative ability of blood serum were observed. The plant-based protein product (FP) helped preserve testosterone level and prevent an increase in catabolic reactions. Moreover, it had a positive effect on both red blood cell hematopoiesis (a smaller increase in the average volume of erythrocytes, the same average concentration and content of hemoglobin, an increased relative red cell distribution width (RDW) and white blood cell hematopoiesis (a beneficial effect for the immune system: lymphocytes, the relative content of neutrophils, monocytes, basophils and eosinophils). The stimulation of humoral immunity was evidenced by beta- and gamma-globulins, an active immune response, the level of IgM and IgG, antioxidant protection, reduction of peroxides and an increase in antioxidant activity of blood serum. The 34-week observation showed a 1.7-fold decrease in the incidence of respiratory illnesses and a 5.7-fold decrease in skin and subcutaneous tissue diseases. Acute respiratory infections were reduced 1.8-fold. There were no cases of community-acquired pneumonia in the treatment group, compared with 55.1‰ in the control group. The incidence of respiratory diseases was 3.3-10.6 times lower in the treatment group than in the control group in weeks 6-19. The findings testify to the prophylactic effect of functional food during social adaptation and acclimatization of students.

Changes in sociocultural attitudes towards appearance, body image, eating attitudes and behaviours, physical activity, and quality of life in students before and during COVID-19 lockdown

BACKGROUND

The coronavirus pandemic resulted in national lockdowns that are associated with a rise in important macro-stressors for populations worldwide. The aim of the present study was to assess the impact of the COVID-19-related lockdown period on the sociocultural attitudes towards appearance, body image, eating attitudes and behaviours, physical activity, and quality of life of Lithuanian university-aged students of both genders.

METHOD

A total of 1850 students completed the body image, health-related behaviour and quality of life assessments three months before the first lockdown, of which 959 provided consent and an e-mail to be contacted by for further surveys. Of these 959, 230 completed the same questionnaire during the second lockdown providing the informed consent for the participation in the COVID-19-impact for the lifestyle study and use their first round data for the comparison with the lockdown. The age of the participants was 23.9 ± 5.4 years. Independent comparisons were used to test lifestyle and body image differences between men and women before and during the lockdown. Paired-sample statistics were conducted to evaluate any changes in the male and female groups separately with Cohen's d employed to represent effect sizes.

RESULTS

No body image or disordered eating changes were found, however, body appearance evaluation increased in women (effect size 0.15). Significant increases in media pressures (in women, effect size 0.16) and the internalization of thin/low body fat beauty ideals (effect size 1.18-1.46) were observed during the lockdown when compared to baseline. No changes in quality of life were evident for men, however, for women, an increase in general and psychological domain was observed (effect size 0.17). We observed a significant decrease in physical activity (in men, effect size 0.46), an increase in internet browsing time (effect size 0.52-0.8), a decrease in unhealthy eating habits (effect size 0.49-0.60), an increase in sleep duration (in women, effect size 0.40) and lower self-rated health (in men, effect size 0.42) during the lockdown when compared to baseline.

CONCLUSIONS

These findings suggest that the majority of students cope with lockdown-related situation well. However, based on the Tripartite influence model, we can speculate that a drastic increase in the internalization of stereotyped thin/low body fat ideals might trigger body image concerns and increase disordered eating after the lockdown. Specific interventions helping students to decrease internalization of stereotyped body ideals, to promote positive body image and physical activity may be beneficial during and after the COVID-19-related lockdown.

An artificial intelligence data mining technology based evaluation model of education on political and ideological strategy of students

The student’s political and ideological practices is a vital portion of education, and it is related to optimization of task based on fundamental scenario in establishing morality. In order to establish a scientific, reasonable and operable evaluation model for students’ ideological education, and evaluate the status of college students’ ideological education. In this paper, firstly, in view of the shortcomings of evaluation objectives, single evaluation methods, lack of pertinence of evaluation indicators and subjectivity of evaluation standards in the current evaluation system of university students’ ideological and political education, the basic principles for constructing evaluation models of university students’ ideological and political education are put forward. Secondly, in case to meet changing needs of the times, an artificial neural network algorithm based on artificial intelligence data mining and a traditional multi-layer fuzzy evaluation model are designed to evaluate the ideological and political education of college students. This newly proposed model integrates learning, association, recognition, self-adaptive and fuzzy information processing, and at the same time, it overcomes their respective shortcomings. Finally, an example analysis is carried out with a nearby university as an example. The evaluation results display that the evaluation model of students’ ideological education established in this paper is in good agreement with the previous evaluation results. It fully shows that the comprehensive evaluation model of fuzzy neural network for college students’ ideological and political education established in this paper is scientific and effective.
