 Poor Kids are Less Likely to be Nearsighted Than Their Wealthier Peers

A scientific team including Chinese government agencies and universities and experts from Stanford University in California have found that poor kids are far less likely to be nearsighted than their wealthier peers.

The study comprised of 20,000 children in China, 9400 students from Shaanxi, where students have greater access to books that require close-up focusing, compared to the poorer neighboring province of Gansu, where more than 10,100 students were part of the study. Researchers tested the vision of fourth and fifth grade students, aged 9-11 years. They found that nearly 23 percent of youths in Shaanxi has clinically significant myopia, nearly twice that of the lower-income province of Gansu, which had a 12.7 percent prevalence rate of myopia.

The study said, "Living in the middle-class area was associated with a 69 percent increased risk for nearsightedness, even after adjusting for other risk factors, such as time spent reading, outdoor activity and whether the student's parents wore glasses. Doing well at math, which requires intensive focus on a written page, was among the factors linked to higher incidence of myopia. Girls were also more likely than boys to be nearsighted."

lead investigator Professor Nathan Congdon said, "We're still on the hunt for a plausible explanation and think the results merit more study into whether using blackboards versus books may be partially responsible for protecting eyes against nearsightedness, and what other factors may play a role. What's important is that we figure out how lower-income Chinese students have avoided nearsightedness so we can use those same strategies to prevent more childhood myopia cases across Asia and perhaps even the world."

The research appears in the journal of the American Academy of Ophthalmology.
