OBJECTIVE: To adapt the Body Shape Questionnaire for use in the Brazilian population; to study the internal validity and the dimensionality of the scale when used in a non- clinical Brazilian population. METHOD: A cross- sectional study was accomplished comprising 164 students in the first 3 years of the School of Medicine conveniently selected at the Universidade Federal de São Paulo. The 34- item Body Shape Questionnaire version and a questionnaire to assess demographic and anthropometric information were used. RESULTS: The internal consistency of the Body Shape Questionnaire measured by Cronbach's alpha was 0.97, indicating that the questions of the scale converge to the same construct. The factor analysis of the scale resulted in a four- dimension solution accounting for 66.4% of the total data variability. Regarding the final score of Body Shape Questionnaire, the mean score was 58.7 ± 25.1 for men and 89.7 ± 31.3 for women. DISCUSSION: We found statistically significant gender differences in the means of the Body Shape Questionnaire scores. Women showed higher dissatisfaction than did men as to their appearance as measured by the Body Shape Questionnaire. The adapted version of the scale seems to maintain the characteristics of the original scale.

Context: The level of body awareness, performance emotional state (PES), and demographic characteristics in different sports are subjects to be investigated. It is important to examine the concepts of PES and body awareness to better understand the body–mind relationship in different sports. Objective: The aim of this study was to investigate the level of body awareness and PES of athletes. Design: In this cross-sectional study, the independent variables are groups (4 different sports), and the dependent variables are body awareness and PES. Participants: The study was conducted on 188 licensed athletes (85 footballers, 36 basketball players, 34 handball players, and 33 swimmers). The mean age of the participants was 14.64 (1.89) years, mean height was 172.44 (11.03) cm, and mean body weight was 62.35 (13.12) kg. Settings: Four sports clubs and 2 high schools were the intervention facilities. Intervention: Body Awareness Questionnaire and Continuous Optimal Performance Emotional Status Scale-2 were used for data collection. Sociodemographic information was recorded. Main Outcome Measures: One-way analysis of variance was used for analysis of normal distribution data in 4 different groups, and the Kruskal–Wallis test was used for the analysis of data that did not show normal distribution. Results: There was no difference in body awareness among the branches (P = .17). The PES of the footballers was better than that of other athletes (P = .01). The correlation between body awareness and PES was medium (r = .47, P < .01), and the correlations between body awareness and age, licensed year, and number of weekly training sessions were weak (r = .22, P < .01; r = .19, P < .01; r = .15, P = .03). Conclusions: The body awareness of athletes may not differ among different sports, but PES is related to many factors such as mood, age, license years, and number of training sessions. In rehabilitation and training, body awareness and PES should be evaluated together.

Background: Due to the pandemic, COVID-19 cases and deaths are increasing unexpectedly and precipitately. More importantly, asymptomatic carriers could infect healthy people through sneezing, coughing, and talking. Therefore, mask usage is required to prevent and control COVID-19. Objectives: This study was aimed at examining the knowledge, attitude, and performance levels (KAP) of the Iranian population regarding mask usage to prevent and control the COVID-19 outbreak during a one-month period from early April to early May 2020. Methods: A researcher-made, validated, and reliable questionnaire consisting of 30 questions on knowledge, attitude, and performance regarding mask usage was utilized. Data collection was performed through the online method. To do so, the online questionnaire link was provided for the participants via social networks. The correct and wrong answers were scored 1 and 0 points, respectively. The final score of each dimension was calculated and classified as 0 - 50% (low), 51 - 75% (moderate), and 75% > (good). Results: A total of 1581 participants took part in the study. Although the participants had good attitude (74%) and performance (70.80%), but only 13.70% of them had good knowledge regarding mask usage. Also, significant differences were found between the participants’ knowledge and higher educational levels (P < 0.001). There were significant associations between the participants’ age, gender, educational level, and job and their knowledge and attitude levels (P < 0.05). Besides, female participants had higher performance scores than did male participants (P < 0.001). The participants with governmental jobs had significantly higher performance than unemployed ones (P < 0.001). Conclusions: The participants obtained low KAP scores; therefore, it is required to train and inform the society and enhance their KAP levels via social media regarding the importance of mask usage, including proper donning, doffing, cleaning, disinfection, and safely and hygienic disposal procedures of masks to prevent and control COVID-19.

Background: Today, the use of dental radiography equipment in dental centers has increased due to its high application in the diagnosis of dental diseases. As a result, concerns are increasing regarding repeated exposure to this low dose level of radiation. Therefore, the knowledge and practice of dentists about radiation protection are essential for themselves and the patients. This study aimed to assess the knowledge and practice of dentists about radiation protection. Materials and Methods: This cross-sectional study was performed based on a questionnaire in several cities of Iran. The first part of the questionnaire included such information as gender, years of work experience, and participation in radiation protection workshops. The second, third, and fourth sections consisted of questions on radiobiology, radiation protection, and performance, respectively. Results: In this study, 94 dentists participated, and the mean scores of dentists (out of 5 points) for radiobiology knowledge, radiation protection knowledge, and performance were obtained at 2.66±1.1, 2.80±1.01, and 2.87±1.37, respectively. The results of Pearson analysis showed that general knowledge had a significant relationship with performance (P=0.014). There was also a significant relationship between the history of participation in radiation protection workshops and performance (P=0.01). Conclusion: It was found that more knowledge about the effects of ionizing radiation on the body and more awareness of the principles of radiation protection would help dentists to better observe the practical principles of radiation protection. Also, participating in radiation protection workshops could increase dentists' knowledge, and therefore, improve their performance.

Taekwondo (TKD) is a Korean combat sport, recognised by Olympics, involving the combination of kick movements which include power, speed, agility, muscular strength and endurance. Nutrition is an important determinant of physical tness of athletes. Cross sectional study was undertaken to investigate the nutritional status along with tness parameters of the 150 TKD players of 8-24 years age through purposive random sampling in training centres of Kolkata. Pre-tested questionnaire was used to elicit information on training pattern, physical, physiological, performance parameters and nutritional status. Mean Vo2max uptake in males ranged between 22.0±2.0-34.±1.8ml/kg/min in 8-24 year athletes whereas in female it was reported 22.3±1.7-32.5±1.9ml/kg/min indicating as low in majority of the athletes. Average performance was observed among the athletes on assessing physical tness components. Adequate consumption of cereals, pulses, milk and vegetables were reported however low consumption was noted in green leafy vegetables, fruits and nuts. Nutritional inadequacy of protein, iron and calcium as indicated through 24 hour diet recall was found signicant difference at 0.05 level. Therefore, guidance in nutrition is required to make prudent dietary choices that will improve the body composition, thereby increasing sport performance.

Objective: To analyze body image in different periods of adolescence. Methods: This cross-sectional study enrolled students aged ten to 19 years old of public schools in small districts of Minas Gerais, Southeast Brazil. The Body Shape Questionnaire (BSQ), the Body Dissatisfaction Assessment Scale for Teenagers and the Silhouette Scale for Teenagers (SST) were used. Adolescence phases were classified according to the subjects' ages. Weight and height were measured in order to calculate the body mass index and the nutritional status. Results were analyzed by logistic regression. Results: The study emolled 531 teenagers (318 females). The average age was 15.6± 2 .2 years and 84.6% were eutrophic. The prevalence of body dissatisfaction varied from 28.9% (BSQ) to 78.9% (SST). Overweight adolescents presented greater dissatisfaction (BSQ: OR 3.66, p<0.001; SST: OR 4.108, p<0.001). Dissatisfaction also occurred for females and those at the early adolescence (p<0.05). Conclusions: A low prevalence of dissatisfaction with the body image was observed among adolescents in small towns of Minas Gerais; however, most of them wished a different silhouette than the current one. The results showed that younger adolescents had higher dissatisfaction than their peers, as well as female and overweighed adolescents.

Background/Aim: Obesity in adolescents is increasing; as such, the aim of this study was to determine the prevalence of obesity in Mexican adolescents and examine its possible association with hours of sleep. Methods: A school-based cross-sectional study was carried out. This study included 863 adolescents aged between 11 and 16 years. The prevalence of obesity was estimated using the body mass index (BMI). The duration of sleep (and other information) was assessed by a self-reported questionnaire. The Cochran–Mantel–Hansel test for categorical variables and a general linear model for continuous variables were used to evaluate the interaction effect of BMI and sex with respect to sleeping and assessed activity conditions. Results: It was found that 47.6% of the adolescents were overweight/obese. Men were more frequently overweight/obese than women (52.6% vs. 41.8%, p = 0.002). Moreover, overweight/obese adolescents were younger and spent fewer daily hours watching television (p < 0.05). Men practiced sports more hours per week than women (p = 0.04). However, women spent more daily time on the internet (p = 0.05), and overweight/obese adolescent women slept fewer hours than overweight/obese men and adolescents with normal weight (p = 0.008). Conclusions: The development of strategies for the prevention of overweight/obesity and the improvement of sleep duration should include a gender perspective to improve health habits in Mexican adolescents.

ObjectivesPsychological distress is a worldwide problem and a serious problem that needs to be addressed in the field of occupational health. This study aimed to use artificial intelligence (AI) to predict psychological distress among workers using sociodemographic, lifestyle and sleep factors, not subjective information such as mood and emotion, and to examine the performance of the AI models through a comparison with psychiatrists.DesignCross-sectional study.SettingWe conducted a survey on psychological distress and living conditions among workers. An AI model for predicting psychological distress was created and then the results were compared in terms of accuracy with predictions made by psychiatrists.ParticipantsAn AI model of the neural network and six psychiatrists.Primary outcomeThe accuracies of the AI model and psychiatrists for predicting psychological distress.MethodsIn total, data from 7251 workers were analysed to predict moderate and severe psychological distress. An AI model of the neural network was created and accuracy, sensitivity and specificity were calculated. Six psychiatrists used the same data as the AI model to predict psychological distress and conduct a comparison with the AI model.ResultsThe accuracies of the AI model and psychiatrists for predicting moderate psychological distress were 65.2% and 64.4%, respectively, showing no significant difference. The accuracies of the AI model and psychiatrists for predicting severe psychological distress were 89.9% and 85.5%, respectively, indicating that the AI model had significantly higher accuracy.ConclusionsA machine learning model was successfully developed to screen workers with depressed mood. The explanatory variables used for the predictions did not directly ask about mood. Therefore, this newly developed model appears to be able to predict psychological distress among workers easily, regardless of their subjective views.
