We studied the prevalence of sedentary behaviors (SB) in children with specific learning disorders (SLD) having an eye on the role of child-parent (C-P) relationships and parenting style (PS). In this descriptive-correlational study, a total of 116 children with SLDs in Malayer city, Iran, whose mothers and fathers participated in the study were selected using the census method. The data were collected using the Child Weekly Screen Time Scale, PS, and C-P Relationship Scales. The data were analyzed using the Pearson correlation coefficient and stepwise regression analysis. The results showed that the hours mean of dealing with SB during the week, weekend, and the whole week in children with SLDs were 22.10, 8.59, and 30.75, respectively. The highest average hours of SB included watching TV, playing with handheld devices (iPhones, iPads, tablets), and playing mobile/no internet, respectively. The results, also, demonstrated a significant correlation between mother and father age, child-mother [C-M] dependency, child-father [C-F], closeness relationship, mother’s permissive PS, father's permissive PS (r=.20) with SB. Father age, father’s permissive PS, C-F callousness, and C-M dependency have been able to predict SB, respectively.
