Scope

Europe in 2010, 2020, 2030, 2050.

Definition

This variable is calculated entirely from upstream variables listed under #Dependencies. Mathematical method described under #Formula.

Dependencies

• heande:Moisture damage
• Population of Europe
• Asthma prevalence
• ERF of indoor dampness on respiratory health effects

Unit

#

Formula

Formula calculates number of asthma cases which can be attributed to dampness in Europe in years 2010-2050 by using the following:

1. <math>extra cases = (prevalence_total - prevalence_nondamp) population</math>
2. <math>prevalence_total = prevalence_nondamp(%damp * OR + 1 - %damp)</math>
3. <math>prevalence_0 = %damp * OR * prevalence_nondamp + (1 - %damp) * prevalence_nondamp</math>

<math>prevalence_nondamp = \frac{prevalence_0}{%damp * OR + 1 - %damp}</math>

• Prevalences for nondamp and damp homes are assumed constant, for a given iteration.
