Long-term exposure to PM1 and thyroid diseases in China.

ABSTRACT:

Background

Globally prevalent, thyroid diseases are linked to environmental factors such as air pollution. This study examines the link between particulate matter (PM)1 exposure and thyroid disease rates in China.

Methods

We analyzed data from 73,900 adults across 31 Chinese provinces, using a high-resolution spatial-temporal extremity tree model to estimate PM1 and PM2.5 levels, and thyroid function tests to assess disease prevalence. Multivariate-adjusted ORs evaluated PM1's link to thyroid disease. This cross-sectional study is adept at identifying associations but cannot establish causality due to its single-time data collection limitation.

Results

Higher PM1 level exposure was significantly linked to an increased prevalence of thyroid diseases, including overt hy
