Abstract

This study aimed to investigate the relationship between workplace conditions (healthy workplace) and sleep quality among firefighters working in Bangkok Metropolitan Area, Thailand. The self-administrative questionnaire was developed from WHO’s 2018 Healthy Workplace Framework. The use of Happy for Life Guideline and Job Content Questionnaire in Thai version (Thai-JCQJ) was for assessing personal characteristics, working characteristics and Healthy Workplace conditions (physical work environment, the psychosocial work environment, personal health resources in the workplace and enterprise community involvement). The Pittsburgh Sleep Quality Index (PSQI) Thai version was used to evaluate sleep quality of firefighters in the past month. Descriptive statistics illustrated included frequency, mean, standard deviation, interquartile range and percentage. Chi-square test, independent t-tests, Mann-Whitney U test and logistic regression statistically tested the relationship between observed factors.

The results showed that out of 301 firefighters, the majority 52.2% encountered poor sleep quality and 39.2% stayed with good sleep quality. Firefighters who attained poor sleep experienced with short sleep duration £ 7 hours at 64.3%, with low sleep efficiency (£ 85.0% of sleep efficiency) at 72.0%. Regarding the workplace conditions according to the WHO’s Healthy Workplace Framework, the reports showed that the physical work environment, personal health resources in the workplace and psychosocial work environment were significantly associated with sleep quality of firefighters. Such findings of this study affirmed the effects of working conditions to sleep quality. The provision and implementation of the healthy workplace handbook within organizations could help better improve the workplace environment in a sustainable manner. It also helps promote health, safety and well-being of firefighters.
