Prevalence and Predictors of Carpal Tunnel Syndrome Symptoms Among Teachers in Jazan: A Cross-Sectional Study

Background Carpal tunnel syndrome (CTS) is a common musculoskeletal condition of the hand and wrist frequently associated with repetitive hand motion and environmental considerations. Teachers are more likely to acquire CTS because of their lengthy writing and computer use. This study aimed to determine the prevalence of CTS symptoms and related variables among schoolteachers in Jazan, Saudi Arabia. Methods This study was conducted as a cross-sectional survey of teachers in Jazan, utilizing an online platform for data collection. The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) was the primary tool used to determine symptom intensity and functional status. The data were rigorously analyzed using a range of statistical methods, including descriptive statistics, the Mann-Whitney U test, the Kruskal-Wallis test, Spearman's correlation, the chi-square test, Fisher's exact test, and binary logistic regression, ensuring the robustness of the findings. Results The study comprised 336 schoolteachers with a mean age of 43.3 ± 6.5 years, of whom 58.0% were female and 42.0% were male. About 8.0% of instructors reported CTS symptoms. Female gender (median Symptom Severity Scale (SSS): 15.0 vs. 12.0, p < 0.001; median Functional Status Scale (FSS): 8.0 vs. 8.0, p < 0.001), increased time spent writing (r = 0.237, p < 0.001 for SSS; r = 0.217, p < 0.001 for FSS), and presence of comorbidities such as diabetes (median SSS: 16.0, p = 0.002; median FSS: 8.0, p = 0.001) had a negative correlation with symptom severity (r = -0.174, p = 0.002) and functional impairment (r = -0.141, p = 0.011). Surgical therapy (median SSS: 32.0; median FSS: 24.0; p<0.001) and post-treatment symptom recurrence (median SSS: 28.0; median FSS: 22.0; p<0.001) were associated with increased severity and disability. According to binary logistic regression, increased writing time significantly predicted CTS diagnosis (OR = 1.151, 95% CI: 1.024-1.295, p = 0.018). Conclusion CTS symptoms are common among Jazan teachers, and various sociodemographic, vocational, and clinical variables influence their intensity and functional status. Ergonomic treatment, early identification, and suitable management measures are critical for preventing and mitigating the effects of CTS among teachers. Additional research is required to develop focused therapies and enhance the results of this occupational group.
