Abstract

Background: Eczema is one of the most common inflammatory dermatoses that can be provoked as a result of external and internal factors. With dense population and rapid economic development of China, air pollution is still a serious problem and the prevalence of eczema has been elevating. Objective: To determine the association and lagged effects between environmental factors and the outpatient visits for eczema. Methods: Data of daily outpatient visits for eczema at the clinics of dermatology in West China Hospital within the last 5 years were collected. Data of environmental factors of Chengdu during the same period, including temperature, relative humidity, barometric pressure, wind speed and air pollutants concentrations like sulphur dioxide (SO 2), nitrogen dioxide (NO 2) and particular matter (PM 10), were gathered. The distributed lag nonlinear model was used to statistically examine the relationship between eczema and environmental factors and their lagged effects. Results: Correlation analysis showed that eczema outpatient visits were positively correlated with the air pollutants and were negatively correlated with relative humidity. The barometric pressure and wind speed influenced the outpatient visits in association with air pollutants. Conclusion: This study provides evidence that environmental factors like relative humidity and multiple air pollutants influence the incidence and prevalence of eczema and have lagged effects.

  • In a time-series analysis conducted from 2011 to 2015 (N=72,305 outpatient visits for eczema) in a hospital in south-western China, Li et al. found a positive correlation between outpatient visits for eczema and air pollutants (NO2, SO2, PM10), but not relative humidity, suggesting that air pollutants specifically increase the symptoms of eczema.

    “In a time‐series analysis conducted from 2011 to 2015 (N = 72 305 outpatient visits for eczema) in a hospital in south‐western China, Li et al.84 found a positive correlation between outpatient visits for eczema and air pollutants (NO2, SO2, PM10), but not relative humidity, suggesting that air pollutants specifically increase the symptoms of eczema.”

  • Our findings support studies on long-term PM2.5 exposure and AD, including indoor air pollution and AD severity in children, AD prevalence among adults, and prenatal pollution exposure.

    “Our findings also support studies on long-term PM 2.5 exposure and AD, including indoor air pollution and AD severity in children, 59 AD prevalence among adults, 60 and prenatal pollution exposure.25”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
