Öğe Differences in physical activity, sedentary time, and anthropometric variables among children and adolescents: The TUBON project(Turkish J Pediatrics, 2024) Demirci, Necip; Karaca, Ayda; Caglar, Emine; Aksen, Pelin; Kucukkubas, Nigar; Celebi, Mehmet Mesut; Karabulut, ErdemBackground. Although physical inactivity may lead to increasing obesity prevalence, research on anthropometric variables changes based on physical activity (PA) in children and adolescents is limited. PA decreases with age, while sedentary behavior increases. The study aimed to examine differences in objectively measured sedentary time, light-intensity physical activity (LPA), and moderate-to-vigorous intensity physical activity (MVPA) between children and adolescents, and the differences in the percentiles of anthropometric variables between physically active and inactive groups according to World Health Organization PA recommendations. Methods. A total of 759 participants aged 6-17 years (boys, n=358; girls, n=401) were included in the study. The ActiGraph wGT3x-BT accelerometer was used to measure sedentary time, LPA, and MVPA. Height, weight, waist circumference (WC), triceps skinfold thickness (T-SFT), and medial-calf skinfold thickness (M-SFT) were measured. Body fat percentage (BF%) and body mass index (BMI) were calculated, and the percentiles of anthropometric variables were categorized. Results. The findings showed that children had less sedentary time and a higher LPA than adolescents for both genders (p<0.05). Children had a higher MVPA than adolescents in girls (p<0.05), but the difference was insignificant in boys (p>0.05). In boys, physically active children were in lower percentiles for T-SFT and BF% than those who did not (p<0.05). In boys, adolescents who were physically inactive were in higher percentiles for BMI, T-SFT, M-SFT, and BF% (p<0.05). In addition, in girls, adolescents who were physically active were in lower percentiles of BMI, M-SFT, and BF%, whereas children who were physically active were in lower percentiles of M-SFT and BF% (p<0.05). Conclusion. Sedentary time increases while PA decreases with age. Children and adolescents who met the WHO PA recommendation had lower percentiles of anthropometric variables, indicating the importance of PA in preventing obesity in these age groups.Öğe Physical Activity Levels of the Young Adults in an Economically Developing Country: The Turkish Sample(Acad Physical Education-Katowice, 2009) Karaca, Ayda; Caglar, Emine; Cinemre, Suekrue AlpanThe purpose of this study was to examine the physical activity levels of the young adults in Turkey, selected as all example of all economically developing country. A total of 1027 university students voluntarily participated ill 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 oil participation duration in the sports activities. This finding showed that males spent more time ill both vigorous and non-vigorous sport activities than females. hi 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 tit both the duration of housework and sitting ill the house. To conclude, males participated in sport activities with a higher intensity and spent more time oil these activities than females. Oil the other hand, females spent much more tit-tic on housework activities and sitting tit the house than males.Öğe The Psychological Characteristics and Health Related Behavior of Adolescents: The Possible Roles of Social Physique Anxiety and Gender(Cambridge Univ Press, 2010) Çağlar, Emine; Bilgili, Naile; Karaca, Ayda; Ayaz, Sultan; Aşçı, F. HülyaThe 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.Öğe Screen Time Differences among Turkish University Students as an Indicator of Sedentary Lifestyle and Inactivity(Fac Teacher Education, 2017) Caglar, Emine; Bilgili, Naile; Karaca, Ayda; Deliceoglu, GokhanThe aim of the present study was to examine the screen time differences as an indicator of sedentary lifestyle in terms of some socio-demographic variables among university students. A total of 2209 university student (M-age = 20.80, SD = 1.61 years) participated in this study. The demographic information and screen time data were collected by using a survey form. The screen time refers to the combined time spent on watching TV/video, watching/playing/working on a computer, and playing video games. Two x three factorial ANOVA revealed significant gender and socioeconomic status differences in the screen time. The male students and those with a high socio-economic status had higher screen time. In addition, one-way ANOVA showed significant screen time differences in terms of parental education level and place of residence (p < .001). The students living in dormitories and those whose parents had lower education level had lower screen time. Also, the students who had an opportunity to access technological devices in their place of residence and in their bedrooms had higher screen time than the students who did not have these facilities (p<.001). The screen time as a sedentary behavior among university students is quite high and these findings can be taken into account as a warning indicating increases in the sedentary lifestyle of these young adults.Öğe Screen time of adolescents in an economically developing country: The case of Turkey(Taylor & Francis Ltd, 2011) Karaca, Ayda; Caglar, Emine; Bilgili, Naile; Ayaz, SultanBackground: Most studies of screen time of adolescents have been carried out in well-developed countries. There is little information concerning screen time of adolescents in developing countries such as Turkey. Aim: This study examined the screen time of adolescents with regard to gender, school type and sport participation in Turkey, selected as an example of an economically developing country. Subjects and methods: A total of 916 high school students participated in this study. The household activities and sport indexes of the Physical Activity Assessment Questionnaire were administered to the participants. Results: Male students had higher screen time (hours/day) than female students and the screen time of the adolescents was longer at the weekends than on weekdays (p < 0.01). The students attending private schools spent more screen time on both weekdays and weekends than those attending public schools (p < 0.01). The results did not reveal significant screen time differences with regard to participation duration in sport activities (p > 0.05). Conclusions: 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.
