The prevalence of active and inactive peptic ulcer was 23% in male workers aged 31-60 at a plastics processing factory in Tokyo. Similarly, the incidence of active and inactive peptic ulcer during one year was 5% or more. The findings from a case control study suggested that smoking and family history were the major aetiological factors. The incidence and prevalence of peptic ulcer in male factory workers in Japan appear to be higher than elsewhere.
东京一家塑料加工厂31至60岁男性工人中,活动性和非活动性消化性溃疡的患病率为23%。同样,一年内活动性和非活动性消化性溃疡的发病率为5%或更高。一项病例对照研究的结果表明,吸烟和家族史是主要病因。日本男性工厂工人消化性溃疡的发病率和患病率似乎高于其他地方。
