Effect of short-term exposure to particulate air pollution on heart rate variability in normal-weight and obese adults.

ABSTRACT:

Background

The adverse effects of particulate air pollution on heart rate variability (HRV) have been reported. However, it remains unclear whether they differ by the weight status as well as between wake and sleep.

Methods

A repeated-measure study was conducted in 97 young adults in Beijing, China, and they were classified by body mass index (BMI) as normal-weight (BMI, 18.5-24.0 kg/m²) and obese (BMI ≥ 28.0 kg/m²) groups. Personal exposures to fine particulate matter (PM_2.5) and black carbon (BC) were measured with portable exposure monitors, and the ambient PM_2.5/BC concentrations were obtained from the fixed monitoring sites near the subjects' residences. HRV and heart rate (HR) were monitored by 24-h Holter electrocardiography
