Characteristics associated with blindness or visual impairment within the adolescent demographic: a national cohort analysis

Abstract

Background: Psychosocial metrics associated with self-reported blindness or visual impairment for adolescents in the National Survey of Drug Use and Health (NSDUH) have not been fully characterized. This retrospective cohort analysis of the latest NSDUH aimed to determine novel characteristics associated with self-reported visual loss among adolescents in the United States.

Methods: Data from the NSDUH2020, a publicly available, federally validated database, were analyzed. Self-reported severe visual impairment or blindness was defined as being truly blind or having serious difficulty seeing even when wearing corrective lenses (s-rSVI). Inclusion criteria were all cases of s-rSVI in adolescents aged 12-17 years. NSDUH weights were used to accommodate complex survey design, nonresponse rates, and population variance. Weighted percentages, asymptotic two-sided Rao-Scott χ² analyses, and multivariable logistic regression were performed. Statistical significance was considered reached at P < 0.05.

Results: A total of 5,667 adolescents aged 12-17 years were surveyed, and s-rSVI occurred in 236 cases (weighted percentage, 3.48%). Within our final multivariable risk model, characteristics associated with increased odds of s-rSVI were female sex, Asian and Latino race/ethnicity (relative to non-Hispanic White), and self-reported serious difficulty hearing and concentrating (all P < 0.05).

Conclusions: This national retrospective cohort analysis highlights risk factors associated with s-rSVI for adolescents within the 2020 NSDUH. Clinicians and policymakers should consider at-risk demographics for s-rSVI during development and enhancement of screening programs, population health initiatives, and healthcare policy issues.
