AI Article Synopsis

  • This study investigates the impact of residential construction patterns on adolescent myopia through a survey of 10th-grade students in a private high school in a megacity in mid-west China.
  • Researchers collected data on students' myopia levels, home addresses, and used satellite imagery to analyze the amount of shadow and greenness around their homes.
  • The findings suggest a negative correlation between myopia levels and the proportion of shadow area, with high-rise apartment buildings potentially acting as a protective factor against myopia progression by increasing available ground space in densely populated areas.

Article Abstract

This study aims to assess how the construction patterns within residential communities influence the adolescent myopia using general survey. In a private high school from a megacity in mid-west China, a questionnaire gathered data on the 10th-grade students' level of myopia, home address, and some potential confounding factors. Additionally, satellite digital images were utilized to calculate the proportion of shadow area (PSA) and the proportion of greenness area (PGA) within a 500 m×500 m area centered on each student's home address. Correlations between myopia levels and PSA, along with other variables, were analyzed. The prevalence of mild, moderate, and high myopia were 39.2%, 32.5%, and 8.3%, respectively. A negative correlation was observed between myopia levels and PSA, albeit marginally significant (r=-0.189*, P = 0.05). Upon dividing the sample into higher and lower PSA groups using a cut-off point of 20%, a significant difference in myopia levels was evident (χ2 = 8.361, P = 0.038), while other confounding factors remained comparable. In conclusion, high-rise apartment constructions, which often cast more shadows on digital satellite maps, may not exacerbate myopia progression. Instead, they could potentially serve as a protective factor against adolescent myopia in densely populated megacities, as they allow for more ground space allocation.
