Age Effect on the Bidirectional Relations Between Alcohol Consumption and Pain

Alcohol consumption reduces but pain rises over the life course. Thus, we hypothesized that developmental variability in the bidirectional association between alcohol consumption and pain would vary as a function of age. This hypothesis was tested across three age groups – younger (<29), middle (29-65), and older (>65) using NESARC wave 1 and 2 data (N=34,653). The effect of pain interference at baseline on alcohol consumption at follow-up was non-significant across the age groups, indicating that self-medication theory was unsupported. The effect of alcohol consumption at baseline on pain interference at follow-up was significant among the middle (Estimate -.007, p=.002) and older (Estimate -.019, p<.001) groups, but non-significant among the younger group. This latter effect differed significantly between the younger and older groups (p =.005) and the middle and older groups (p=.041). Results show that alcohol consumption reduces pain interference, especially later in life.
