Purpose: Many older workers are working despite having neck-shoulder pain (NSP), which may give rise to work limitations due to pain, especially among those with high physical work demands. This study investigated the joint association of neck-shoulder pain intensity and physical work demands with work limitations among older workers.
Methods: In SeniorWorkingLife, workers ≥ 50 years (n = 11,800) replied to questions about NSP intensity, work limitations due to pain, and physical activity demands at work. The odds ratio for having a higher level of work limitations due to pain in relation to neck-shoulder pain intensity and physical work demands were modeled using logistic regression controlled for various confounders.
Results: The results showed that the neck-shoulder pain intensity was associated with work limitations in a dose-response fashion (p < 0.0001). Importantly, a significant interaction existed between neck-shoulder pain intensity and physical activity at work (p < 0.0001), e.g., 77% of workers with high pain and high work demands experienced work limitations due to the pain.
Conclusion: Higher neck-shoulder pain intensity and higher physical work demands-and particularly in combination-were associated with higher odds of work limitation due to pain among older workers. Thus, it seems especially important to accommodate work demands through a better work environment for these groups of workers.
