摘      要：The short-term associations of ambient temperature exposure with lung function in middle-aged and elderly Chinese remain *** study included 19,128 participants from the Dongfeng-Tongji cohort s first(2013)and second(2018)*** lung function for each subject was determined between April and December 2013 and re-assessed in 2018,with three parameters(forced vital capacity[FVC],forced expiratory volume in 1 s[FEV1],and peak expiratory flow[PEF])*** China Meteorological Data Sharing Service Center provided temperature data during the study *** the two follow-ups,a total of 25,511 records(average age:first,64.57;second,65.80)were evaluated,including 10,604 males(41.57%).The inversely J-shaped associations between moving average temperatures(lag01–lag07)and FVC,FEV1,and PEF were observed,and the optimum temperatures at lag04 were 16.5
C,18.7
C,and 16.2
C,*** lag04,every 1
C increase in temperature was associated with 14.07 mL,9.78 mL,and 62.72 mL/s increase in FVC,FEV1,and PEF in the lowtemperature zone(the optimum temperatures),whereas 5.72 mL,2.01 mL,and 11.64 mL/s decrease in the high-temperature zone(the optimum temperatures),respectively(all P0.05).We observed significant effect modifications of gender,age,body mass index,body surface area,smoking status,drinking status,and physical activity on the associations(all Pmodification0.05).Non-optimal temperatures may cause lung function *** individual characters and lifestyles have effect modification on the temperature effects.
