Association between Exposure to Ambient Air Particulates and Metabolic Syndrome Components in a Saudi Arabian Population.

Recent epidemiological evidence suggests that exposure to particulates may be a factor in the etiology of metabolic syndrome (MetS). In this novel study, we investigated the relationship between particulate levels and prevalence of MetS component abnormalities (hypertension, hyperglycemia, obesity) in a recruited cohort (N = 2025) in Jeddah, Saudi Arabia. We observed significant associations between a 10 μg/m³ increase in PM and increased risks for MetS (Risk Ratio (RR): 1.

Temporal variations of fine and coarse particulate matter sources in Jeddah, Saudi Arabia.

Unlabelled: This study provides the first comprehensive analysis of the seasonal variations and weekday/weekend differences in fine (aerodynamic diameter <2.5 μm; PM) and coarse (aerodynamic diameter 2.5-10 μm; PM) particulate matter mass concentrations, elemental constituents, and potential source origins in Jeddah, Saudi Arabia.
