Suo Jen, a tuberculosis specialist at Taoyuan General Hospital, points out that before the age of 35, the disparity between males and females is not great. But with advancing age, the difference becomes increasingly evident, and by age 67, the ratio of male to female victims reaches three to one. Some surmise that the disparity is related to hormonal effects, but as yet no firm conclusions have been reached.
衛生署桃園醫院結核病專科醫師索任指出，在三十五歲以前，男女差異不大，但隨年齡增長，差異越來越明顯，到六十七歲時，男女盛行率擴大為三比一，有人推測這與荷爾蒙有關，但至今仍無定論。
