Risk Factors and Behaviours of Schoolchildren with Myopia in Taiwan

  • This study investigated the risk factors for myopia and their influence on the progression of myopia in schoolchildren in Taiwan.

  • Patients’ clinical records were obtained retrospectively from ophthalmologists. Questionnaires were given to collect demographic information, family background, hours spent on daily activities, myopia progression, and treatment methods.

  • From a regional medical hospital in northern Taiwan, 522 schoolchildren with myopia participated in the study.

  • Written informed consent was obtained from participants of legal age or the parents or legal guardians of younger children.

  • Multivariable regression analyses were performed. Myopia measured in cycloplegic spherical equivalent (SE) was analysed, controlling for patients’ family and demographic information as well as their daily activity behaviours.

  • Children with high myopic parents were more myopic.

  • Earlier onset age of myopia was associated with a higher level of myopia and greater annual myopic progression.

  • Children reporting longer time usage of electronic devices had greater progression of myopia. Boys tended to be more myopic than girls.

  • Lower levels of myopia were associated with more outdoor activities, and better vision care knowledge in children and parents.

  • In addition to genetics, education and environment can influence the development of myopia.

  • Health policies for schoolchildren should promote protective activities and vision care knowledge at a young age, to protect the eyesight of schoolchildren.
