The Impact of Pain Reduction on Productivity and Cognitive Function in a Low-Income Population
Physical pain is a common but largely overlooked and poorly understood aspect of the lives of the poor. With frequent involvement in hard physical labor, uncomfortable living conditions, and limited access to adequate medical care, the poor are particularly likely to experience pain (Poleshuk and Green 2008; Johnson et al. 2013, Tsang et al. 2008). This heavy burden of physical pain is likely to be exacerbated in the coming years as pain increases with age and populations are aging rapidly around the globe (Loeser and Melzack 1999; McBeth and Jones 2007).
