Abstract

Mycobacterium avium complex (MAC) pulmonary disease is prevalent in middle-aged to elderly women with a thin body habitus. By comparing the rate of serologically diagnosed asymptomatic MAC infection and body mass index among 1033 healthy subjects, we find that middle-aged to elderly women became infected with MAC, regardless of their body habitus.

Keywords: Japan; Mycobacterium avium complex; non-tuberculous mycobacteria.
