The study population comprised respondents who reported chronic neck pain (CNP) without comorbid chronic respiratory diseases (CRDs) in the 2011 survey. Pain sites were assessed via self-reported questionnaires, and CRDs were confirmed based on self-reported prior diagnoses. Logistic regression was employed to analyze the association between CNP and CRDs.Results: A total of 6864 participants were included, with 650 developing CRD during the follow-up. After adjusting for confounding factors such as gender, age, and other chronic diseases, CNP was significantly associated with incident CRD (OR = 2.25, 95% CI: 1.77– 2.86, P < 0.0001). Gender-stratified analyses revealed that the positive association between CNP and CRD risk remained significant in both males (OR = 3.08, 95% CI: 2.11– 4.48, P < 0.0001) and females (OR = 1.87, 95% CI: 1.37– 2.57, P < 0.0001), with a stronger magnitude observed in males.Conclusion: Among Chinese CNP patients aged ≥ 45 years, the risk of developing CRD is increased by 2.25-fold, with evident gender differences. In clinical and community practice, conducting respiratory health assessment and screening for middle-aged and elderly patients with CNP (chronic neck pain), and initiating rehabilitation training as early as possible, is of vital importance for reducing their risk of developing chronic respiratory diseases.Keywords: chronic neck pain, chronic respiratory diseases, cohort study, CHARLS
