During the past nine years from 1991 to 1999, Minatomachi Medical Center and other organizations have provided free medical check-ups for foreigners in Kanagawa, Tokyo and Chiba. Eighty-five percent of the total of the 2370 examined were over-staying foreigners who were not covered by national health insurance system. The ratio of male to female was two to one and the most of them were in the twenties and thirties. As for their ethnic origins from forty-three countries, the Filipinos were the largest numbers, followed by Koreans, Iranians, Bangladeshi, and Chinese/Taiwanese. As a result of chest radiographs, 82% were normal, 8.3% mostly normal, 9.6% tuberculosis shadow (TBS) including active, non active and previous, 0.09% suspected pneumonia, 0.05% suspected cardiac disease, and 0.05% suspected sarcoidosis. The TBS and active tuberculosis (ATB) rates of all examined were 9.6% and 0.69% respectively. There was no significant difference in each TBS and ATB rate between the two sexes. Seen from the age group, it was found that the more aged they were, the higher the TBS and the ATB rates were. The TBS and the ATB rates were 24.6% and 2.73% in the Koreans, 10.7% and 0% in the Chinese/Taiwanese, 10.2% and 0.65% in the Filipinos, 11.3% and 1.44% in the South-East Asians, 6.3% and 0.25% in the South Asians, 2.3% and 0% in the Iranians, 3.7% and 0% in the sub-Saharan Africans, 8.5% and 0.61% in the Latin Americans, and 0% and 0% in the Europeans/North Americans. Based on a presumed ATB rate of 0.75%, approximately two thousand cases with ATB could be calculated to exist among the estimated 270,000 over-staying foreigners. It is, therefore, important to give them more frequent medical check-ups for early detection of latent cases with ATB.
在1991年至1999年的过去九年里，水町医疗中心及其他机构为神奈川、东京和千叶的外国人提供了免费体检。接受检查的2370人中，85%是未加入国民健康保险体系的逾期滞留外国人。男女比例为二比一，他们大多为二十多岁和三十多岁。在来自43个国家的受检者中，菲律宾人数量最多，其次是韩国人、伊朗人、孟加拉国人以及中国人/台湾人。胸部X光检查结果显示，82%正常，8.3%基本正常，9.6%有结核阴影（包括活动性、非活动性和既往性），0.09%疑似肺炎，0.05%疑似心脏病，0.05%疑似结节病。所有受检者的结核阴影率和活动性肺结核（ATB）率分别为9.6%和0.69%。男女之间的结核阴影率和ATB率均无显著差异。从年龄组来看，发现年龄越大，结核阴影率和ATB率越高。韩国人的结核阴影率和ATB率分别为24.6%和2.73%，中国人/台湾人为10.7%和0%，菲律宾人为10.2%和0.65%，东南亚人为11.3%和1.44%，南亚人为6.3%和0.25%，伊朗人为2.3%和0%，撒哈拉以南非洲人为3.7%和0%，拉丁美洲人为8.5%和0.61%，欧洲人/北美人为0%和0%。基于假定的0.75%的ATB率，估计27万逾期滞留外国人中可能有大约2000例ATB病例。因此，对他们进行更频繁的体检以早期发现潜伏的ATB病例很重要。
