Scope
Exposure-response function for short-term (acute) exposure to ambient air particulate matter (PM) with an aerodynamic diameter < 2.5 µm and minor restricted activity days (MRADs). MRAD is defined as a day when a person needs to make minor restrictions to his/her normal daily activities because of ill-health. Minor refers to restrictions less severe than having to stay in bed or stay out work.
Dimensions and boundaries relevant for the variable
- Age of exposed population
- Country/other geographic area
Definition
Data
Ostro & Rothschild (1989)[1]
Minor restricted activity days (MRADs) among adults aged 18-64:
- 0.74% (95% Cl 0.60%, 0.88%) increase in MRADs per 1 µg/m3 PM2.5
- change of 577 MRADs (95% Cl 468, 686) per 10 µg/m3 PM2.5 per year per 1000 adults
- Assumes a background rate of 7.8 MRADs per person per year
