Voice Disorder Prevalence and Vocal Health Characteristics in Adolescents.

Importance: Voice disorders impede communication and detract from quality of life, yet little is known about how voice problems present in adolescents. This study characterized the prevalence of voice problems and vocal health characteristics of adolescents throughout the US.

Objective: To determine the prevalence of adolescent voice problems in the US as well as the symptoms, voice use patterns, and risk factors associated with these problems.

Design, setting, and participants: This prospectively performed, cross-sectional survey study conducted from March to June 2023 included a probability sample of adolescents (aged 13-17 years) who were located across the US.

Main outcome and measures: Adolescents were surveyed concerning voice use, voice symptoms, demographic information, and substance use patterns. The Vocal Fatigue Index (VFI) was also completed. Fisher exact tests, χ2 tests, and logistic regression were used to compare those with and without reported voice problems.

Results: Five-hundred and two adolescents participated (51.6% participation rate), including 248 female (49.4%), 7 nonbinary (1.3%), 254 male (50.6%), 4 transfemale (0.7%), and 3 transmale individuals (0.5%) (mean [SD] age, 15.2 [1.3] years). The lifetime prevalence of voice problems was 24.3%, and current prevalence was 7.4%. Voice-related diagnoses included dysphonia associated with acute illness, vocal hyperfunction, benign lesions, and muscle tension. The mean (SD) VFI score was 4.7 (8.09) for part 1, 1.6 (3.2) for part 2, and 2.1 (3.2) for part 3. Adolescents with voice complaints presented with significantly higher VFI scores than those without voice problems (Cohen d for part 1 = 0.78, part 2 = 0.59, and part 3 = 0.79). Voice problems interfered with daily tasks, prevented participation in extracurricular activities, limited the ability to sing, and were associated with school absences. Voice use patterns associated with voice problems included frequent loud voice use, coughing, and/or throat clearing. Risk factors for increased voice problem prevalence included part-time employment in childcare (odds ratio [OR], 6.4; 95% CI, 1.6-26.3), singing (OR, 2.08; 95% CI, 1.3-3.1), performance-related extracurricular activities (ie, musical theater [OR, 2.67; 95% CI, 1.1-6.6 ], karaoke [OR, 3.08; 95% CI, 1.3-6.9]), vaping (OR, 1.99; 95% CI, 1.1-3.5), and/or secondhand smoke exposure (OR, 1.83; 95% CI, 1.2-2.7). Adolescents identifying as transgender were more than 4 times (OR, 4.44; 95% CI, 0.63-31.2) as likely to report voice problems compared with cisgender adolescents.

Conclusions: The results of this survey study illuminate the nature of voice problems in adolescents and may guide clinicians in preventing and treating voice disorders in this population. Future work may define the mechanisms through which these factors are associated with the risk for voice disorders in adolescents and determine whether observed relationships are causal or associative.
