Resumo
Com o surgimento de computadores pessoais, smarthphones, tablets e videogames, surge também novo comportamento da população mundial, caracterizado pelo uso excessivo dessas telas. Mundialmente, essas novas tecnologias estão cada vez mais presentes na vida dos adolescentes, e seu uso se tornou desregrado. Em 2020, a Sociedade Brasileira de Pediatria lançou um manual com orientações aos pais, estabelecendo que adolescentes com idades entre 11 e 18 anos fiquem, no máximo, 3 horas diárias diante de telas, inclusive videogames. Consequências a saúde física e mental têm sido observadas como: fatores de risco para doenças cardiovasculares, obesidade, sedentarismo, sono insatisfatório e depressão. Alterações posturais também têm sido evidenciadas: protrusão da cabeça e hipercifose torácica foram achados em grupos de universitários que faziam uso excessivo de telas. Objetivo: Esse estudo objetiva identificar as alterações posturais em adolescentes associado ao uso excessivo de telas. Método: O presente estudo caracteriza-se por uma abordagem descritiva transversal observacional de adolescente com idade entre 14 e 18 anos de ambos os sexos. Os questionários utilizados foram o Physical Activity Questionnaire for Adolescents- PAQ-A, Hábitos de uso de mídias interativas em adolescentes, Fatores Associados aos Sintomas Osteomusculares pelo uso do Smartphone em Jovens e a postura foi avaliada através de fotogrametria posteriormente analisadas por meio do aplicativo de celular PhysioCode Posture (Sistema para Avaliação da Postura e do Movimento), tendo como valores de referência para cervical na vista anterior: alinhado – 0 grau e desvio - 3,11 graus; vista lateral: alinhado – 52,42 graus e desvio – 5,40 graus . Resultados: A amostra coletada totalizou 89 jovens, sendo 45 do sexo feminino e 44 do sexo masculino. Verificou-se na análise postural em vista lateral direita da cabeça, que os valores angulares se encontram acima da média de referência, e na vista anterior, observa-se elevação de ombro em 34 participantes. Quando questionados sobre o tempo de uso do smartphone, 70 respondentes afirmaram usar diariamente 4 horas ou mais o aparelho, sendo a posição sentada a mais adotada durante o seu manuseio. Nota-se também quanto a postura, que a manutenção da cervical em flexão de 45º é a mais adotada durante o uso o smartphone; e que 45 participantes indicaram queixas como dor, formigamento ou dormência na cervical. Uso excessivo de telas resulta em alteração no alinhamento da coluna cervical e o aumento na angulação de flexão de cervical associado ao tempo maior de uso de telas resulta em regiões de desconforto no corpo. Conclusão: O uso excessivo de telas resulta em alterações posturais, principalmente em coluna cervical. Se tornando um problema de saúde pública, requerendo atenção para desenvolvimento de programas educativos e de prevenção.
With the emergence of personal computers, smarthphones, tablets and video games, there is also new behavior of the world population, characterized by the excessive use of these screens. Worldwide, these new technologies are increasingly present in the lives of adolescents, and their use has become unruly. In 2020, the Brazilian Society of Pediatrics released a manual with guidelines for parents, establishing that adolescents between the ages of 11 and 18 spend a maximum of 3 hours a day in front of screens, including video games. Consequences to physical and mental health have been observed as: risk factors for cardiovascular diseases, obesity, sedentary lifestyle, unsatisfactory sleep and depression. Postural alterations have also been evidenced: head protrusion and thoracic hyperkyphosis were found in groups of university students who made excessive use of mesh. Objective: This study aims to identify postural changes in adolescents associated with excessive use of screens. Method: The present study is characterized by a descriptive cross-sectional observational approach of adolescents aged between 14 and 18 years of both sexes. The questionnaires used were the Physical Activity Questionnaire for Adolescents - PAQ-A, Habits of use of interactive media in adolescents, Factors Associated with Musculoskeletal Symptoms by the use of the Smartphone in Young People and posture was evaluated through photogrammetry later analyzed through the mobile application PhysioCode Posture (System for Evaluation of Posture and Movement), having as reference values for cervical in the anterior view: aligned - 0 degree and deviation - 3.11 degrees; Side view: aligned – 52.42 degrees and deviation – 5.40 degrees. Results: The sample collected totaled 89 young people, 45 females and 44 males. It was verified in the postural analysis in the right lateral view of the head, that the angular values are above the reference average, and in the anterior view, shoulder elevation was observed in 34 participants. When asked about the time of use of the smartphone, 70 respondents said they use the device daily 4 hours or more, with the sitting position being the most adopted during its handling. It is also noted regarding the posture, that the maintenance of the cervical in flexion of 45º is the most adopted during the use of the smartphone; and that 45 participants indicated complaints such as pain, tingling or numbness in the cervical. Excessive use of meshes results in alteration in the alignment of the cervical spine and the increase in cervical flexion angulation associated with the longer time of mesh use results in regions of discomfort in the body. Conclusion: The excessive use of meshes results in postural changes, especially in the cervical spine. It becomes a public health problem, requiring attention for the development of educational and prevention programs.
