【摘要】：目的了解我國成人呼吸量的分布情況。方法基于"中國居民環(huán)境暴露行為模式研究(成人)"于2011年11月—2012年5月通過測量方式獲得我國31個省、自治區(qū)、直轄市居民身高和體重的基礎(chǔ)上,采用人體能量代謝估算法計算出我國居民的長期和短期呼吸量。分析我國居民長期和短期呼吸量的性別、年齡、城鄉(xiāng)和地區(qū)分布特征以及影響因素,并與國內(nèi)外相關(guān)研究進(jìn)行了對比。結(jié)果我國居民的長期呼吸量為15.7 m3/d,在休息、坐、輕微活動、中體力活動、重體力活動和極重體力活動下的短期呼吸量分別為5.5、6.6、8.2、21.9、32.9和54.8 L/min。與國內(nèi)研究相比,本研究基于最新的居民身高、體重等數(shù)據(jù),更具有代表性;與國外比較,也存在著一定的差異。結(jié)論我國成人的呼吸量存在地區(qū)、性別、年齡等差異,在進(jìn)行空氣暴露健康風(fēng)險評價時,應(yīng)選擇居民實際呼吸量參數(shù)。
[Abstract]:Objective to investigate the distribution of adult respiratory volume in China. Methods the height and weight of the residents in 31 provinces, autonomous regions and municipalities were measured from November 2011 to May 2012. The long-term and short-term respiration of Chinese residents was calculated by energy metabolism estimation. The sex, age, distribution of urban and rural areas and influencing factors of long-term and short-term respiratory volume of Chinese residents were analyzed and compared with related studies at home and abroad. Results the long-term breathing capacity of Chinese residents was 15.7 m3 / d. The short-term respiration rates under rest, sitting, mild, moderate, heavy and extremely heavy physical activities were 5.56.6and 8.2221.9m32.9 and 54.8 L / min, respectively. Compared with domestic research, this study is more representative based on the latest data such as height and weight of residents, and there are some differences compared with foreign countries. Conclusion there are regional, gender and age differences in respiratory volume of adults in China. The actual breathing parameters should be selected when evaluating the health risk of air exposure.
