nvironmental irritants are important risk factors for

skin diseases, but little is known about the influence of

environmental factors on eczema incidence. In this time-

series study, our objective was to examine the associations of

environmental factors with outpatient visits for eczema. Daily

outpatient visits between 2007 and 2011 (1826 days) were

collected from Huashan Hospital in Shanghai, China. We used

an over dispersed generalized additive model to investigate

the short-term association between environmental factors

and outpatient visits for eczema. Daily outpatient visits for

eczema were significantly associated with air pollution and

meteorological factors. For example, a 10 μg/m3 increase of

7-day (lag 06) average concentrations of PM10 (particulate

matter no greater than 10 microns), was associated with 0.81%

(95% confidence intervals (CI) 0.39%, 1.22%), 2.22% (95% CI:

1.27%, 3.16%) and 2.31% (95% CI: 1.17%, 3.45%) increase in

outpatient visits for eczema, respectively. A 10 °C elevation of

temperature on lag 0 day were associated with 8.44% (95%

CI: 4.66%, 12.22%) increase in eczema visits, whereas 10 unit

decrease of 7-day average relative humidity were associated

with 10.86% (95% CI: 8.83%, 12.89%) increase in eczema visits.

This study provided clear evidence of ambient air pollution,

high temperature and low relative humidity on increasing the

incidence of eczema in Shanghai, China.

Anqi Li, a student in West China School of Medicine, Sichuan University, who is

studying for the master degree under Professor LI Li. My study research is about the

air pollution and skin diseases especially skin allergy. During my study in university I

am a top student and have been awarded The First-class Scholarship, Excellent Student

Leader Scholarship for my high grades, excellent performance in examinations and

devotion to the services to the Student Association. I worked for 2 years in outpatient

department of dermatology and 6 months in hospitalized wards of dermatology in

West China Hospital, Sichuan University. The major work was involved in diagnosis

and treatment of daily general skin problems. Also I actively participated in overseas

student teaching program in the ward of dermatology.
