Dependência de smartphone e/ou tablets e dor cervical em universitários: um estudo preliminar

Abstract

Excessive use and dependence on smartphones and tablets have increased significantly, especially among young people, and are often associated with neck pain and impaired quality of life. This study aimed to investigate the association between smartphone and/or tablet dependence, perceived posture during the use of these devices, and the occurrence of neck pain in university students. This is an observational, cross-sectional study with a sample of 82 students of both sexes, aged between 18 and 30 years. Data were collected through an online questionnaire containing sociodemographic information, the Smartphone Addiction Inventory – Brazilian version (SPAI-BR) to assess smartphone dependence, as well as questions about the presence of neck pain and self-perceived posture. The results showed that 86.6% of participants were classified as at risk of dependence, and 67.1% reported episodes of neck pain in the past 12 months. The majority (58.5%) reported adopting postures considered inadequate when using mobile devices. However, no statistically significant associations were found between smartphone dependence and neck pain, nor between perceived posture and the presence of pain. It is concluded that, despite the high prevalence of technological dependence and neck pain, no significant association was observed between these variables, suggesting the influence of multiple biopsychosocial factors on the pain experience. Future longitudinal studies are recommended to further explore this relationship.
