Objective: There is limited information on cold-related pain (CRP) in various parts of the body among workers employed in cold environments. We, therefore, determined the prevalence of CRP among Thai chicken industry workers and attempted to identify vulnerable subgroups. Methods: Four hundred and twenty-two workers in four chicken meat factories in Thailand were asked about CRP in the face, upper limbs, and lower body. The results were expressed as adjusted prevalence and prevalence differences [PD; in percentage points (pp)] and their 95% confidence intervals (CI). Results: Overall, 80% of the subjects suffered from CRP in at least one site on the body: 66% in the upper limbs, 65% in the lower body, and 44% in the face. In most sites, CRP increased from the lowest to the highest educational level, notably in the nose with a PD of 36 pp [95% CI 23, 49]. Forklift drivers experienced knee pain [PD 21 pp (0, 41)], and manufacturing [PD 27 pp (15, 38)] and storage workers [PD 24 pp (10, 37)] experienced thigh pain more often than office workers, while office workers reported CRP in the cheeks, ears, wrists, and fingers more often than other workers. Women had more CRP than men in several body sites. Conclusions: The majority of workers suffered from CRP. Intensified protective measures should be targeted not only for forklift drivers and storage and manufacturing workers, but also for the highly educated as well as the office staff who showed excessive prevalence of CRP in several body sites.
