Background Childhood adversities ( CA s) have been associated with adult‐onset chronic pain. However, to date, most single country studies on this association have been undertaken in Western countries. This study examined the association in Japan where information is scarce. Methods Data were drawn from the World Mental Health Survey Japan, a population‐based cross‐sectional survey undertaken in 11 areas of Japan in 2002–2006. We analyzed data from adults aged ≥20 years who provided information on CA s occurring before age 18 years and chronic pain ( n = 1740). Cox proportional hazard models were used to estimate the risk for different forms of adult‐onset chronic pain (arthritis/rheumatism, neck/back pain, headache and any pain) as a function of the presence of 11 different types of CA and the number of CA s. Results In the adjusted models, significant associations were observed between: physical abuse and neck/back pain ( HR 2.55) and any pain ( HR 1.88); sexual abuse and any pain ( HR 2.84). Significant dose‐dependent relationships were also observed between a greater number of CA s and some adult‐onset chronic pain conditions (neck/back and any pain). Conclusions The results of this study suggest that in Japan, some forms of CA may be associated with certain types of adult‐onset chronic pain, in particular neck/back pain.
