[Impact of Air Pollutants on Outpatient Visits for Pediatric Atopic Dermatitis in Lanzhou].

Objective To analyze the correlation between air pollutants and pediatric atopic dermatitis outpatient visits in Lanzhou,and provide scientific insights for the life guidance of the affected children and disease prevention by relevant departments.Methods A generalized additive model was employed to analyze the effects and lagged effects of air pollutants on pediatric atopic dermatitis outpatient visits in Lanzhou while controlling for confounding factors such as long-term trends,holiday effects,day of the week effects and meteorological factors.Results The effects of NO,PM,PM,and SO on pediatric atopic dermatitis outpatient visits were most significant on the current day(Lag0),but were not statistically significant (all >0.

[Effects of Temperature on Outpatient Visits for Urticaria among Lanzhou Residents Based on Distributed Lag Non-linear Model].

Objective To evaluate the influence of temperature on the outpatient visits for urticaria in Lanzhou City and its hysteresis and to find out the sensitive populations by sex and age stratification.Methods We collected the urticaria outpatient data in three grade A class three hospitals as well as the meteorological data and air pollutant data in Lanzhou from January 2011 to December 2017.The distributed lag non-linear model(DLNM)was employed to analyze the influence of daily mean temperature on the outpatient visits for urticaria.

[Effects of Air Pollutants on Outpatient Visits for Atopic Dermatitis in Lanzhou].

Objective To quantitatively evaluate the associations of PM,PM,NO,and SO concentrations with the outpatient visits for atopic dermatitis in Lanzhou. Methods The data of outpatient visits,together with meteorological data and air pollutant data,from January 2013 to December 2017 were collected.The generalized additive model based on Poisson distribution was employed to study the lag effects of PM,PM,NO,and SO concentrations on the visits of outpatients,with the seasonal and long-term trends and day-of-the-week effect controlled.

[Effect of Gaseous Pollutant Concentration on the Number of Daily Outpatient Visits for Acne in Lanzhou].

Objective To determine the relationship between air pollutants [SO,NO,8 hours average concentration of ozone(O8h)] and outpatient visits for acne in Lanzhou,China. Methods Data of daily outpatient visits for acne and concentrations of air pollutants(SO,NO,and O8h)from January 2013 to December 2017 were collected.With the control of long-term trend and day-of-week effect,a distributed lag nonlinear model was used to analyze the lag and cumulative effects of air pollutants on the outpatient visits.
