Screen time can play a significant role in the health and quality of life of people with disabilities. However, there is a lack of studies on this issue among people with disabilities, and even fewer in the university setting. Thus, the aim of our study was to explore the relationships between screen time, disability grade, body mass index (BMI), physical activity and sociodemographic variables (gender and socioeconomic status) in university students with different disabilities.
A cross-sectional study was conducted on a sample of 1091 students with disabilities from 55 Spanish universities. Instruments used for data gathering were the Adolescent Sedentary Activity Questionnaire (ASAQ) and the International Physical Activity Questionnaire-Short Form (IPAQ-SF). A Self-Organizing Maps (SOM) analysis was carried out to explore the relationships between the variables under study.
Participants reported high values in overall screen time (5.45 h per day/week), with computers being the media most used (2.45 h per day/week). The SOM analysis showed slightly higher screen time values in women than men. People with a high disability grade spent less screen time than those with lower disability grade. Contradictory results exist when a group of men with the highest BMI had the highest screen time and the lowest physical activity (PA) while women with low BMI show the highest screen time and PA.
Gender and disability grade played a moderating role in screen time among people with disabilities while BMI and PA do not play such a role.
屏幕时间在残疾人士的健康和生活质量中起着重要作用。然而，针对残疾人士的此类研究甚少，在大学生群体中更是如此。因此，我们的研究旨在探索不同残疾程度的大学生中，屏幕时间与残疾等级、身体质量指数（BMI）、身体活动以及社会人口学变量（性别和社会经济地位）之间的关系。
我们对来自西班牙 55 所大学的 1091 名残疾学生进行了横断面研究。数据收集工具包括青少年久坐活动问卷（ASAQ）和国际体力活动问卷-短卷（IPAQ-SF）。我们采用自组织映射（SOM）分析来探索研究变量之间的关系。
参与者报告的总体屏幕时间值较高（每天/每周 5.45 小时），使用最多的媒体是电脑（每天/每周 2.45 小时）。SOM 分析显示女性的屏幕时间略高于男性。残疾程度较高的人比残疾程度较低的人花在屏幕上的时间少。而具有较高 BMI 的男性群体的屏幕时间最长、身体活动（PA）最低，同时 BMI 较低的女性群体的屏幕时间和 PA 最高，这与我们的预期结果相悖。
性别和残疾等级在残疾人士的屏幕时间中起着调节作用，而 BMI 和 PA 则没有起到这样的作用。
