【摘要】：目的了解我国成人呼吸量的分布情况。方法基于"中国居民环境暴露行为模式研究(成人)"于2011年11月—2012年5月通过测量方式获得我国31个省、自治区、直辖市居民身高和体重的基础上,采用人体能量代谢估算法计算出我国居民的长期和短期呼吸量。分析我国居民长期和短期呼吸量的性别、年龄、城乡和地区分布特征以及影响因素,并与国内外相关研究进行了对比。结果我国居民的长期呼吸量为15.7 m3/d,在休息、坐、轻微活动、中体力活动、重体力活动和极重体力活动下的短期呼吸量分别为5.5、6.6、8.2、21.9、32.9和54.8 L/min。与国内研究相比,本研究基于最新的居民身高、体重等数据,更具有代表性;与国外比较,也存在着一定的差异。结论我国成人的呼吸量存在地区、性别、年龄等差异,在进行空气暴露健康风险评价时,应选择居民实际呼吸量参数。
[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.
