Contents
Scope
This includes a verbal definition of the spatial, temporal, and other limits (system boundaries) of the variable. The scope is defined according to the use purpose of the assessment(s) that the variable belongs to.
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
Description of the data used for obtaining the value of the variable (e.g. measurement data; mathematical method and its parameters). Please include references (preferably using the <ref></ref> tags) and links to original data, as appropriate.
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
Causality
List of upstream variables. The variables can be listed used descriptive (free-format) names or unambiguous identifiers (e.g. Analytica IDs).
Unit
Unit in which the result is expressed.
Increase in no. of MRADs per 10 µg/m3 increase in exposure per 1000 people aged 18-64
Formula
Algebra or other explicit methods if possible (e.g. Analytica code between the ''<anacode></anacode>'' delimiters).
Result
If possible, a numerical expression or distribution.
Age group | MRADs | 95% Cl |
---|---|---|
15-64 | 577 | 468, 686 |
