This study aimed to clarify the degree of utilization of off-campus and club activity instructors in high school club activities and examined its association with coaches’ health status. All club activity coaches, mostly teacher, at Japanese high schools were included. The survey items included the following: school (area, establishment, and number of students), club (type, number and sex of athletes, activity status, and aim), and coach (sex, age, teaching license, teaching career, marital status, smoking, drinking, exercise, medical history, subjective health status, K6 scale, and utilization of off-campus and club activity instructors). The proportion of utilization of off-campus and club activity instructors were analyzed. The odds ratios (ORs) of utilization of off-campus instructors and club activity instructors for good subjective health status were calculated. In addition, the ORs for a good K6 score was determined. A total of 7,892 coaches responded. Of these, 22.0% utilized off-campus instructors and 7.4% utilized club activity instructors. In athletic clubs, coaches who used off-campus instructors demonstrated superior health outcomes. Among culture clubs, the ORs were not significant. However, among athletic clubs, the ORs (95% confidence interval) of utilization of off-campus instructors for subjective health status (good/bad) and the K6 score (13-20 points/0-4 poinst) were 0.74 (0.55-0.98) and 1.68 (1.19-2.37), respectively. Longitudinal studies are needed in the future.
