AbstractIn the present population-based prospective study, we examined the associations of psychosocial factors with the incidence of herpes zoster (HZ) and postherpetic neuralgia (PHN). Data were collected from 12,359 participants (≥50 years of age) who answered a self-completed health questionnaire in the Shozu County of Kagawa Prefecture in Japan. During a 3-year follow-up between December 2008 and November 2012, HZ and PHN were diagnosed in 400 and 79 subjects, respectively. We used Cox regression analysis to estimate hazard ratios of incident HZ and PHN according to psychosocial factors, adjusting for age, sex, histories of HZ, cancer, and diabetes, smoking and drinking habits, and time from disease onset to treatment. Men with high levels of mental stress were twice as likely to be at risk for incident HZ. The risk of incident HZ was approximately 60% lower among men and women who reported a high sense of purpose in life. Women who experienced negative life events-particularly changes in their work, living environment, and relationships-had a 2- to 3-fold higher risk of incident PHN. Psychosocial factors such as perceived mental stress, sense of purpose in life, and negative life events may contribute to the development of HZ and PHN in the general population.© The Author(s) 2017.
