Total Productive Maintenance (TPM) programs may improve workers’ health and safety. We studied 14 food industry workers undergoing a TPM program, and 40 health care workers with comparable work schedules not undergoing such a program. The median Work Ability Index (WAI) score was 43 (interquartile range, IQ 42 - 45) among food industry workers, and 44 (IQ 41 - 45) among healthcare workers (p = 0.86). However, the sickness leave score was significantly lower in food industry workers (p = 0.03). Our results support the efficacy of TPM programs in reducing sickness leave indicators and ability to countermeasure aging effects among workers.
