Survey of 929 VDT Workers in Shenzhen on Work Hours, Stress, Sleep, and Neck Dysfunction

929 video display terminal workers from 10 companies in Shenzhen, China, were surveyed in a cross-sectional study. The data, authored by Liuzhuo Zhang and last updated in June 2026, examines associations between weekly work hours, occupational stress, sleep quality, and cervical spine dysfunction. It includes measurements from standardized instruments like the Neck Disability Index, Job Content Questionnaire, and Pittsburgh Sleep Quality Index.

Use Cases

• Analyze the association between categorized weekly work hours and cervical spine dysfunction based on the Neck Disability Index.
• Investigate the mediating roles of occupational stress and sleep quality on the work hours-neck dysfunction relationship.
• Model the odds of neck dysfunction using multivariable logistic regression based on the provided confounders and mediator variables.

Strengths

• Data from 929 participants provides a substantive sample size for analysis.
• Uses standardized, validated instruments (NDI, JCQ-22, PSQI) for measuring key constructs.
• Study design and statistical methods, including mediation analysis with bootstrap resamples, are clearly documented.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a specific cross-sectional study in Shenzhen, China, which may limit generalizability.
