Objective To evaluate effects of the daily average temperature on the daily number of outpatient visits for eczema in Lanzhou city.Methods Clinical data were obtained from outpatients with eczema in the Department of Dermatology of 2 third-grade class-A hospitals in Lanzhou city from January 1st 2007 to December 31st 2015,and meteorological data during this period were also collected.Controlling for confounding factors like long-term trends and day of the week,a distributed lag non-linear model (DLNM) fitted with quasi-Poisson link function was used to assess the effects of daily average temperature on the daily number of outpatient visits for eczema,and the analysis was stratified by season,age and gender.Results The exposure-response relationship between the daily average temperature and daily number of outpatient visits for eczema could be roughly described by a W-shaped curve.Stratification analysis showed that the effect of the daily average temperature on outpatient visits for eczema was strongest in autumn and winter,followed by summer,and weakest in spring.Low temperature may have lagged,cumulative and persistent effects on the daily number of outpatient visits for eczema,with the maximum relative risk (RR) value (1.12 [95% CI:1.03-1.22]) observed at-9 ℃ on lag day 14.With a 1 ℃decrease in the temperature,16% (RR =1.16,95% CI:1.00-1.03),14% (RR =1.14,95% CI:1.02-1.26) and 13% (RR =1.13,95% CI:1.02-1.25) increases in the daily number of outpatient visits for eczema were observed in men,teenagers and middle-aged adults respectively (P < 0.05).However,low temperature had no significant effects on outpatient visits for eczema among women or the elderly (P >0.05).The effect of high temperature usually occurred following exposure without lag periods,and was gradually weakened over lag time (P > 0.05).Conclusions In Lanzhou,the effect of daily average temperature on outpatient visits for eczema was strongest in autumn and winter.Changes of the daily temperature may be one of risk factors for eczema.Low temperature had lagged effects on the daily number of outpatient visits for eczema,and the effects were strongest on lag day 14.

Objective To evaluate effects of daily average temperature on the occurrence of urticaria in Lanzhou city,and to analyze differences in the effects between different populations.Methods Time-series data on daily outpatient visits for urticaria between January 1,2007 and December 31,2013 were collected from the First Hospital of Lanzhou University and Lanzhou University Second Hospital.Daily meteorological data during this peroid were obtained from the Gansu Meteorological Bureau.Distributed lag non-linear models were used to analyze the association between daily average temperature and occurrence of urticaria,and the analysis was stratified by age and gender.Results The association between daily average temperature and daily number of outpatient visits for urticaria was nonlinear.Low temperature had significant lag effects on the daily number of outpatient visits for urticaria,with the maximum relative risk (RR) value (1.014 [95% CI 1.000-1.023]) observed at 6 ℃ on lag day 18.Stratification analysis demonstrated that the effects of high temperature on the number of outpatient visits for urticaria were apparent on the day of exposure in age groups of 0-18 and 19-64 years,but decreased on the day of exposure in the age group ≥ 65 years.The effects of low temperature,which showed similar trends along with the increment of lag days in all groups,were relatively delayed and occurred 2 to 4 days after exposure.Conclusions Air temperature affects the occurrence of urticaria in Lanzhou city.Low temperature has evident lag effects on the occurrence of urticaria,while high temperature does not have.
