The new UK research revealed some of the factors that can contribute to the child's risk of developing myopia, finding that children born in summer and those who spend more time playing computer games are at a high risk of developing the disease.
The study by King's College London studied 1,991 twins with an average age of 16.7 years who participated in the Twins Early Development Study (TEDS) study in the long term.
The researchers collected data on demographic, social, economic, educational and behavioral factors in twin pairs at various points between the ages of two and 16 years, in order to analyze the critical stages of child and ocular development.
Opticians were responsible for providing information about myopia taken from the eye tests of children, with parents and teachers who asked to complete the questionnaires to provide information on other potentially relevant factors.
The findings, published in the British Journal of Ophthalmology, showed that in general, one in four (26 percent) of the twins was short-sighted. The average age at which children with myopia began to use lenses to correct the disease was 11.
The researchers also found that the strongest factors associated with the development of myopia were born during the summer, the number of hours children spent playing computer games and the mother's educational level.
The team explained that, like US children. UU. Been born in the summer months they begin the school to a smaller age than the ones born in the winter months, they also begin to work close, for example with the books, which can accelerate the growth of the eyes and cause miopeo. More hours playing computer games can also be linked to nearsightedness due to close work and because more time spent playing indoors means less time outdoors, a factor that has also been previously associated with an increased risk of myopia.
The results also showed that fertility treatment was associated with a risk of less than 25 to 30 percent developing myopia. The team suggested that as children born as a result of the treatment of fertility are often less and slightly premature, they may have a delay in development that can lead to a lower ear length and less myopia.
Myopia, also known as short-sightedness or near-sightedness, is a condition in which the eye can not focus light correctly, which means that the closed objects appear clear but distant appear blurred. It can be corrected with contact lenses or contact lenses, as well as laser surgery, but it is linked to a greater risk of visual deterioration and loss of vision in the later life.
The condition is increasingly common, with 4,758 million people worldwide planned to be affected by 2050, from 1,950 million in 2010.
In a related editorial, the doctors of the National Eye Center of Singapore, the Eye Research Center, Melbourne, Australia and the University of Melbourne, indicated that the study used data collected before the huge increase in digital media, which could also play a role .
"The increase in screen time of the device (DST) resulting from games, social networks and digital entertainment has led to an increase in sedentary behavior, poor diet and lack of outdoor activity," they said. "The use and misuse of smart devices, especially in our pediatric populations, should be monitored closely to address the emerging phenomenon of digital myopia." KM
