Patterns of outpatient visits by Japanese male expatriates in Thailand.

Objective of this study is to clarify the health-related conditions of Japanese male expatriates in Thailand. Records of Japanese male expatriates in their 30s to 50s who consulted outpatient clinics at Bangkok Hospital in 2005 were analyzed for number and type of outpatient visits then compared with data from the "Patient Survey" 2005 for age-matched males in Japan. "Diseases of the respiratory system" and "Certain infectious and parasitic diseases" had a higher rate of diagnosis among Japanese men living in Thailand than those living in Japan. "Endocrine, nutritional and metabolic diseases," and "Mental and behavioral disorders" had a lower rate of diagnosis among Japanese men living in Thailand than those in Japan. "Acute upper respiratory infections" accounted for 87.4% of "Diseases of the respiratory system" and "intestinal infections" accounted for 59.9% of "Certain infectious and parasitic diseases" among expatriates. Japanese male expatriates have a tendency of not visiting hospital when they have no subjective or objective symptoms. To support a healthy expatriate life, health information should be propagated widely and available support services, such as counseling via e-mail or fax, should be actively promoted. Expatriates should be informed of the availability of these services before they go abroad and during their stay.
