Chronic pain affects ∼20% of the adult population and is associated with smoking. Smoking and pain worsen each other in the long term, but short-term temporal associations between smoking and pain throughout the day are unclear. Understanding these relationships may inform strategies for managing comorbid smoking and pain. ⋯ Further research is needed on interventions that combine tailored smoking cessation treatments and behavioral pain management strategies. PERSPECTIVE: This analysis of momentary data reported throughout the day by people with back pain who smoke revealed novel insights into short-term relationships between pain and smoking. Study results can inform future treatment development for individuals with chronic pain who smoke.

Chronic pain is a serious and prevalent condition that can affect many facets of life. However, uncertainty remains regarding the strength of the association between chronic pain and death and whether the association is causal. We investigate the pain-mortality relationship using data from 19,971 participants aged 51+ years in the 1998 wave of the U. ⋯ This attenuation highlights the role of confounders of the pain-mortality relationship as potentially modifiable upstream risk factors for mortality. Posing the depressive symptoms variable as a mediator rather than a confounder of the pain-mortality relationship resulted in stronger evidence of a modest causal effect of pain on mortality (eg, HR: 1.08, 95% CI: 1.01-1.15). Future work is required to model exposure-confounder feedback loops and investigate the potentially cumulative causal effect of chronic pain at multiple time points on mortality.
