Exposure to Particulate Matter Air Pollution and Age of Menarche in a Nationwide Cohort of U.S. Girls.

ABSTRACT:

Background

It remains unclear whether in utero and childhood exposure to air pollution affects pubertal development, particularly age of menarche in girls.

Objective

The aim of this study was to determine whether residential ambient particulate matter (PM) exposure in utero and during childhood is associated with age of menarche.

Methods

We studied 5,201 girls in the Growing Up Today Study 2 (2004-present) who were 10-17 y of age at enrollment (47.7% premenarchal; 52.3% postmenarchal). Exposure to three size fractions of PM [fine PM with aerodynamic diameter ≤2.5μm (PM2.5), PM with aerodynamic diameters between 2.5μm and 10μm (PM2.5-10), and PM with aerodynamic diameter 10μm (PM10)] was assigned based on maternal residential address, updated every 2 y, u
