Lifestyle, mental health, and awareness of health among Japanese bus drivers

To examine lifestyle, mental health and awareness of health, a self-administered questionnaire survey was performed among 751 employees of a bus company in a rural city of Japan. From 597 (79.5%) respondents, we analyzed 130 male bus drivers and age-matched 130 male clerks. The questionnaire included eleven questions about lifestyle and mental health, three questions about awareness of health, and questions on personal concern about specific parts of the body or diseases, and health information they needed. Answers for lifestyle and mental health were classified into the categories of "good" or "not good" practices recommended by Breslow and Morimoto. The results were as follows; 1) Over 80 percent of subjects of both groups had good awareness of health, but bus drivers had significantly worse lifestyle with regard to nutritional intake (p < 0.05), daily walking (p < 0.001), sports (p < 0.05), and sleeping hours (p < 0.001). 2) Bus drivers had significantly greater prevalence of concern about their cardiovascular system, esophagus and gastrointestinal system, and joints and bones than clerks (p < 0.05). 3) Bus drivers had a significantly greater need for information about nutritional intake (p < 0.001), and methods for prevention of diseases (p < 0.01). From these results, the discrepancy between awareness of health and lifestyle seen in this study, especially in food intake, walking time, sports participation, and sleep, may have resulted from the bus driver's characteristics of job, for example, long and irregular working hours. Therefore, effective guidance on health and lifestyle changes to restore balance and improve their lifestyle.
