Objectives To examine the association of neck and shoulder discomfort (Katakori) with somatization and work-related factors (job demand, job control, and worksite support) in Japanese workers.
Methods Cross-sectional data from 2,022 Japanese workers were analyzed using a logistic regression model to examine the association between Katakori and somatization. A multiple logistic regression model was used to examine the association between Katakori and work-related factors (long working hours, job control, and support from colleagues and supervisors) after adjusting for possible confounding factors.
Results The odds of Katakori were higher among respondents with somatic symptoms than among those without (OR = 2.81 and 95 % CI 2.10-3.75 for 1 symptom vs. no symptoms; OR = 3.86 and 95 % CI 2.92-5.12 for 2+ symptoms vs. no symptoms). Lack of worksite support was significantly associated with Katakori (adjusted OR = 2.62; 95 % CI 1.79-3.83). Long working hours and a lack of job control were not significantly associated with Katakori.
Conclusions Katakori may be a form of somatization. A significant association was observed between Katakori and lack of worksite support from colleagues or supervisors. An increase in the social support provided at work may decrease the prevalence of this condition and improve workers' well-being, but more research is needed to substantiate this hypothesis.
