Background We previously reported that the health status of overweight Chinese COPD patients were significantly better than those in normal weight patients, but not in Japanese patient. In this study, we examined the relationships between the health status and BMI in Mongolia, compared with those in China and Japan.
[Method] We examined factors affecting the health status of Mongolians from 2012 to 2013. Participants were local residents of 50‐79 years old (n=521). Health status was measured using COOP/WONCA charts, and information such as symptoms and medical history were reported by participants. Pulmonary function was measured by spirometer, and physician evaluated airflow limitation by GOLD criteria. Data of 782 subjects (399 Chinese, 383 Japanese) in the previous study were compared with those of Mongolian.
[Result] Healthy Mongolian subjects showed significantly higher BMI than those of healthy Japanese and Chinese. COPD patients in Mongolia and Japan, but not in China, showed significantly lower BMI than healthy subjects. BMI was inversely‐correlated with COPD GOLD stage health status only in Chinese male patients. There was no significant effect of BMI on health status and prevalence of respiratory symptoms among Mongolian and Japanese patients.
Conclusion There was no difference in health status between healthy and COPD subjects in Mongolia and Japan. Despite of the difference of medical environment between Mongolia and Japan, the health statuses of patients were not correlated with BMI in Mongolia and Japan. There is limitation that the differences of proportion of severity of COPD between these three countries. Since Chinese COPD patients contained those with more advanced stage, it became a limitation for accurately compare patients across three countries.
