Cardio-Respiratory Effects of Air Pollution in a Panel Study of Outdoor Physical Activity and Health in Rural Older Adults.


ABSTRACT:

Objective

To examine cardio-respiratory effects of air pollution in rural older adults exercising outdoors.

Methods

Adults 55 and over completed measurements of blood pressure, peak expiratory flow and oximetry daily, and of heart rate variability, endothelial function, spirometry, fraction of exhaled nitric oxide and urinary oxidative stress markers weekly, before and after outdoor exercise, for 10 weeks. Data were analyzed using linear mixed effect models.

Results

Pooled estimates combining 2013 (n?=?36 participants) and 2014 (n?=?41) indicated that an interquartile increase in the air quality health index (AQHI) was associated with a significant (P?ConclusionsWe observed acute subclinical adverse effects of air pollution in rural older adults exercising outdoors.
