This study aimed to evaluate ST and its association with physical activity, overweight and socioeconomic status (SES) in children 10 to 12 years of age in Sanandaj.</p> <p style="text-align: justify;"><strong>&nbsp; Methods:</strong> This study was designed as a cross-sectional study, which was conducted in Sanandaj in 2015. ST and physical activity data were collected using the Modifiable Activity Questionnaire (MAQ). Overweight indices are defined based on BMI age- and gender-specific percentiles, as proposed by WHO criteria. Considering household assets data, SES was calculated using principal component analysis (PCA). The relationship between ST and different determinants was assessed using logistic regression analysis.</p> <p style="text-align: justify;"><strong>&nbsp; Results:</strong> Based on the results obtained in our study, 47.28% (95% CI: 45.33-49.24) of the participants spent more than two hours a day on television and video watching and electronic games playing. People who spend greater time on ST activities, independent of their physical activities, are more susceptible to overweight and obesity (p=0.002). People in higher socioeconomic groups spent more time on watching TV and video and playing electronic games (p=0.001). There was a direct relationship between the residential area and ST (P=0.052). ST in male was found to be greater (p=0.033). In addition, ST was also lower in school-aged children whose mothers had a greater education (p=0.56).</p> <p style="text-align: justify;"><strong>&nbsp; Conclusion:</strong> Based on the results of this study, it is recommended to increase the education level and knowledge of mothers and design interventions consistent with children gender and residential location so that to reduce ST and its associated outcomes in children.</p> Screen time behavior, Socio-economic inequality, Inactivity, Physical activity, Children. 1079 1087 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-1081&slc_lang=en&sid=1 Ghobad Moradi moradi_gh@yahoo.com 200319475328460025837 200319475328460025837 Yes Social Determinants of Health Research Center and Department of Epidemiology and Biostatistics, Kurdistan University of Medical Sciences, Sanandaj, Iran.
