The purpose of this study was to examine the physical activity levels of the young adults in Turkey, selected as an example of an economically developing country.A total of 1027 university students voluntarily participated in this study. The sport and household activity indexes of the Physical Activity Assessment Questionnaire (PAAQ) were administered to the subjects. Student t-test showed gender differences in the intensity of the sport activities index (p<0.001). The results of 2 (gender) x 2 (intensity of sport activities) univariate ANOVA revealed significant gender, intensity differences and significant gender x intensity interaction on participation duration in the sports activities. This finding showed that males spent more time in both vigorous and non-vigorous sport activities than females. In terms of the type of engagement in sport activity, the majority of males primarily played soccer, while females had primarily walked. The Student t test revealed gender differences in both the duration of housework and sitting in the house.To conclude, males participated in sport activities with a higher intensity and spent more time on these activities than females. On the other hand, females spent much more time on housework activities and sitting in the house than males.

Study aim: The purpose of this study was to examine smartphone-using university students’ musculoskeletal system pain complaints, duration of smartphone and computer usage, participation in moderate-vigorous physical activities (MVPA), and prolonged sitting time.Material and methods: This study was conducted on Hitit University students (n = 387; 206 female, 181 male) in the province of Çorum. The International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Activity Assessment Ques­tionnaire (PAAQ) (sports/exercise activities section), and a personal information form prepared by the researchers were used as data collection tools. Descriptive statistics and the t-test were used to determine differences between groups. The Pearson chi-square test was used to examine the relationship between categorical variables.Results: It was observed that half of the participants with musculoskeletal system pain complaints (54.5%) feel the pain in all four areas (neck, shoulder, upper and lower back). There was no statistically significant relationship between physical activity intensity and pain complaint (p > 0.05). The students with musculoskeletal pain complaints spend more time on the smartphone and computer than students who do not have pain complaints (p < 0.05). During electronic device usage, the students who are in the low-intensity physical activity category spend more time sitting down than students in the moderate/vigorous intensity physical activity category (p < 0.05).Conclusions: In consequence, information can be provided about the importance of reducing sitting time during smartphone use and increasing the duration of moderate/vigorous-intensity physical activity (PA) so awareness can be raised on the issue among university students.

Male adolescents and students attending private schools had a higher screen time rate than their counterparts, both on weekdays and at the weekend. Participating in sport for different durations did not make any difference to the screen time of these adolescents.

The purpose of this study was to examine whether or not the social physique anxiety level and gender have an influence on psychological characteristics and health related behavior of adolescents. Five hundred and ninety eight female (M age = 14.95, SD = .70 years) and three hundred and eighty four male (M age = 15.08, SD = .76 years) adolescents voluntarily participated in this study. The Social Physique Anxiety Scale (SPAS), three subscales of the Physical Self-Description Questionnaire, and the Multidimensional Perfectionism Scale as indicators of psychological characteristics were administered to all participants. The Eating Attitude Test and Physical Activity Assessment Questionnaire were used to determine health related behavior. It was found that adolescents with high levels of SPA (HSPA) had more unfavourable eating attitudes, higher scores in socially-prescribed perfectionism, negative global physical self-worth and negative body related perceptions than those with low levels of SPA (LSPA). Physical activity levels of adolescents did not differ in the two SPA groups (high/low level). In addition, male adolescents in the present study were more physically active and had favorable eating attitudes and more positive self-perceptions of body fat and general physical self-worth than their female counterparts.El objetivo de este estudio fue investigar si el nivel de ansiedad física social y el género tienen o no, influencia sobre las características psicológicas y la conducta saludable de los adolescentes. En esta investigación participaron voluntariamente 598 chicas (M age = 14.95, SD = 0.70 años) y 384 chicos (M age = 15.08, SD = 0.76 años) en edad adolescente. Como indicadores de las características psicológicas, a todos los participantes se les aplicó la Escala de Ansiedad Física y Social (SPAS), tres subescalas del Cuestionario de Auto-percepción Física, y la Escala Multidimensional de Perfeccionismo. El Test de Actitudes Alimentarias y el Cuestionario de Valoración de Actividad Física fueron utilizados para determinar la conducta saludable. Se descubrió que los adolescentes con altos niveles de ansiedad física social (HSPA) poseían más actitudes alimentarias desfavorables, mayores puntuaciones en perfeccionismo socialmente prescrito, menor autoestima física y percepciones negativas en relación con su cuerpo, que aquellos con bajos niveles de ansiedad física social (LSPA). Los niveles de actividad física de los adolescentes no se diferenciaban en los dos grupos (alto y bajo nivel de ansiedad física social). Además, en el presente estudio, los varones adolescentes eran físicamente más activos, tenían buenas actitudes alimentarias, una más positiva auto-percepción de la grasa corporal y una mejor autoestima física general, que sus homólogas femeninas.Palabras clave: ansiedad física social, actitudes alimentarias, perfeccionismo, yo físico, actividad física.
