Insights

Puerto Rican children and adolescents exhibit the highest rates of uncorrected binocular distance visual impairment among U.S. Hispanic populations. Older age and female gender are linked to increased prevalence of uncorrected visual impairment.

Area of Science:

  • Ophthalmology
  • Public Health
  • Pediatrics

Background:

  • Uncorrected refractive errors are a significant cause of visual impairment globally.
  • Hispanic populations in the U.S. may face unique barriers to eye care access.
  • Understanding visual impairment prevalence is crucial for targeted public health interventions.

Purpose of the Study:

  • To determine and compare the prevalence of uncorrected binocular distance visual impairment.
  • To analyze rates across different U.S. Hispanic subgroups: Cuban-Americans, Mexican-Americans, and Puerto Ricans.
  • To identify demographic factors associated with visual impairment in these groups.

Main Methods:

  • Analysis of data from the Hispanic Health and Nutrition Examination Survey (1982-1984).
  • Inclusion of 6-19 year-old participants from Cuban-American, Mexican-American, and Puerto Rican backgrounds.
  • Assessment of visual acuity using standard methods like Sloan Letters or Landolt Rings.

Main Results:

  • Prevalence rates of uncorrected binocular distance visual impairment (20/30 or worse) were 15.5% (Cuban-Americans), 14.9% (Mexican-Americans), and 23.6% (Puerto Ricans).
  • Puerto Ricans showed significantly higher rates compared to Cuban-Americans and Mexican-Americans (p < 0.05).
  • Adolescents (13-19 years) and females had higher rates than younger children (6-12 years) and males, respectively.

Conclusions:

  • Puerto Rican children and adolescents have the highest prevalence of uncorrected binocular distance visual impairment within the studied Hispanic groups.
  • Older age and female gender are significant risk factors for higher rates of uncorrected visual impairment.
  • Findings highlight the need for culturally sensitive vision screening and intervention programs for Hispanic youth.
