本文报道了日本人呼吸甲烷排出量的调查结果。231例日本受试者的甲烷排泄率为15%，显著低于加拿大和美国报告的33-60%。在18-29岁的男性中，甲烷排泄的患病率仅为3%。但随着年龄的增长而增加，50-59岁的男性和女性几乎达到25- 27%的相同值。当父母双方都是甲烷生产者时，67%的孩子也是甲烷生产者。另一方面，当父母双方都不生产甲烷时，只有6%的孩子是甲烷生产者。在日本居住4年或更长时间的白种人中，甲烷排泄的患病率为55%。这与加拿大和美国报告的水平相同。家族成分和种族起源的影响表明，呼吸甲烷排泄强烈受遗传因素的影响。
A survey of breath methane excretion in Japanese is reported in this paper. The prevalence of methane excretion was 15% in 231 Japanese subjects, which was significantly lower than the range 33-60% reported in Canada and the USA. The prevalence of methane excretion was only 3% in males between the ages of 18-29 years old. However, it increased with age, and both males and females within the ages of 50-59 years old reached to almost the same value of 25-27%. When both parents were methane producers, 67% of their children were also methane producers. On the other hand, only 6% of the children were methane producers when both parents were methane non-producers. The prevalence of methane excretion was 55% in Caucasians who have lived in Japan for four years or longer. This is the same level reported in Canada and the USA. The effect of familial component and ethnic origin suggested that breath methane excretion is strongly affected by genetic factors.
