[Prevalence of coexisting diabetes mellitus among patients with active pulmonary tuberculosis].

We investigated the prevalence of coexisting diabetes mellitus among patients with active pulmonary tuberculosis by the time of admission, sex and age among 2659 active pulmonary tuberculosis patients admitted to National Chiba Higashi Hospital during the 8 years period from 1987 to 1994. Out of total patients, 352 patients were diagnosed as having coexisting diabetes mellitus and the rate was 13.2%. Prevalence of coexisting diabetes mellitus among active pulmonary tuberculosis during the period from 1991 to 1994 was significantly higher than that from 1987 to 1990. The prevalence in male was higher than that in female significantly. The prevalence was particularly higher in male of 40s (22.0%), and 50s (21.3%), than that in the other age groups.
