Abstract

The prevalence of childhood eczema is increasing in many countries. Epidemiological studies, however, say little of its association to outdoor air pollution and climate factors. We conducted a nationwide survey of middle-school students in Taiwan from 1995 to 1996. The 12-month prevalence of eczema was compared with air monitoring station data of temperature, relative humidity, and criteria air pollutants. A total of 317,926 children attended schools located within 2 km of 55 stations. Prevalence rates of recurrent eczema were 2.4 and 2.3% in boys and girls, respectively, with prevalence rates of flexural eczema 1.7% in both sexes. After adjustment for possible confounders, flexural eczema was found to be associated with traffic-related air pollutants, including nitrogen oxides and carbon monoxide. Recurrent eczema was associated with traffic-related air pollution only in girls. There were no associations for the highest monthly means of temperature, whereas the annual means and the lowest monthly means of temperature were negatively related to flexural eczema, but only in girls. The lowest monthly mean relative humidity was positively related to eczema. The results suggest that air pollution and climatic factors, which showed stronger associations in girls than boys, may affect the prevalence of childhood eczema.

  • Wildfires in North America have resulted in downwind air pollution, causing rises in CO concentrations to levels that have been associated with a higher prevalence of AD.

    “More recently, wildfires in North America have resulted in downwind air pollution, causing rises in CO concentrations [16] to levels that have been associated with a higher prevalence of AD [17].”

    From The Burden of Air Pollution on Skin Health: a Brief Report and Call to Action (2024) · cites this paper as [17]

    The Results and Table 4 report an association between higher CO and flexural eczema prevalence, but the statistically significant CO result was limited to Taiwanese schoolgirls. Table 2 gives annual CO concentrations in the studied communities; the paper does not establish that the wildfire-related concentrations mentioned in the citing sentence reached comparable levels. The wildfire pollution itself is attributed to a different citation. (LLM, conf=0.85)

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.
