The results of measurements of peak flow made on 2,891 office workers and others attending a public health exhibition in the City of London have been analysed. After standardizing for height, peak flow was found to increase with age into the third decade before declining again, and there was evidence of a more rapid decline among continuing smokers than among those who had never smoked or had given up. Possible effects of exposure to air pollution were considered in terms of residential histories: mean peak flows for subjects born in London were a little below those of subjects born elsewhere.
对2891名在伦敦市参加公共卫生展览的上班族及其他人员进行的峰值流量测量结果进行了分析。在对身高进行标准化后,发现峰值流量在第三个十年前随年龄增长而增加,之后再次下降,并且有证据表明,持续吸烟者的下降速度比从不吸烟或已戒烟者更快。根据居住史考虑了接触空气污染的可能影响:出生在伦敦的受试者的平均峰值流量略低于出生在其他地方的受试者。
