He was born in the summer and Hours devoted to computer games are connected at a higher risk of developing short or mild myopia (myopia) in childhood, points to twin research, published in the digital edition of the British Journal of Ophthalmology. But fertility treatments can be protective, results show.
Miopia is defined as a refractive error, which means that the eye can not properly focus the light, which leads to cleaning objects in the vicinity, but distant objects are blurred. It can be corrected with glasses, laser surgery or contact lenses, but the condition is associated with an increased risk of visual deterioration and loss of vision in later life.
And it's a disease that's becoming commonplace: It is likely that in the year 2050, 4,500,758 million people worldwide will be affected, compared with 1,950 million in 2010. It is thought that genes play a role in the disorder, but do not fully explain the increasing prevalence. And given the rapid development of the eyes in early life, the researchers wanted to explore possible environmental factors throughout their lives.
These experts studied 1991 twins whose age was 16.7 years, on average. Gemini was born between 1994 and 1996 in the United Kingdom, and participated in the research of the early development of a long term twin (TEDS).
The researchers analyzed demographic, social, economic, educational and behavioral patterns in doubles when these children were 2, 3, 4, 7, 8, 10, 12, 14 and 16 years, to capture the critical phase of child and eye development.
Parents and teachers filled exhaustive questionnaires and twins evaluated on the Internet to provide a wide range of potentially relevant information and background factors that could influence early life development.
The average age of children with myopia began to wear glasses to correct the condition for 11 years. About one in 20 (5.4 percent) had "lazy eye" (amlibia) and similar proportionality (almost 4.5 percent) had strabismus. Overall, one in four (26%) twins was short-sighted.
Factors that were most strongly associated with the development of myopia at different time points were the educational achievement of the mother (university or postgraduate level), hours devoted to computer games and birth during the flight. Hours spent in computer games can be associated only with close work, but also with less time outdoors, a factor previously associated with an increased risk of myopia.
Educational level is also associated with myopia and how a child born in the UK born in the summer months begins In a younger age than those born during the winter months, scientists suggest that this close work can accelerate the growth of the eye, which is responsible for the myopia.
LESS OF THE MIOPIA IN THE CHILDREN FIGHTING LAST FAMILY
Levels higher household income and intelligence measurements, In particular, the results of verbal skills are associated with greater risk, but to a lesser extent. It seems that the therapy protected fertility from myopia and was associated with a 25-30% reduction in risk.
Researchers, members of the Department of Academic Ophthalmology at the Royal College of London, London, UK, speculate that children born as a result of fertility treatment are often born less and slightly premature, and may have some level of delayed development, which could explain the shorter eye length and less Myopia.
However, it is the observers of studies, and as such can not determine the cause, researchers say, pointing out that future research may be able to analyze the interaction between genetic susceptibility and environmental impact.
