Scope

What is the association between exposure to indoor dampness and mould in homes and respiratory health effects?

Definition

Data

Odds ratios for different health effects in homes with vs. without visible dampness and/or mold or mold odor. [1]
Outcome Subjects No. studies Odds ratio central estimate (95 % CI) Estimated % increase in damp homes
Upper respiratory tract symptoms All 13 1.70 (1.44–2.00) 52
Cough All 18 1.67 (1.49–1.86) 50
Adults 6 1.52 (1.18–1.96) –
Children 12 1.75 (1.56–1.96) –
Wheeze All 22 1.50 (1.38–1.64) 44
Adults 5 1.39 (1.04–1.85) –
Children 17 1.53 (1.39–1.68) –
Current asthma All 10 1.56 (1.30–1.86) 50
Ever-diagnosed asthma All 8 1.37 (1.23–1.53) 33
Asthma development All 4 1.34 (0.86–2.10) 30

Dependencies

Unit

OR per yes/no visible dampness and/or mold or mold odor

Formula

  • Generates random samples of possible ORs.
    • Normal distribution assumed, sd estimated from confidence interval using sd = (upper bound - lower bound)/3.92
n <- 10000
erf <- rnorm(n, 1.56, (1.86-1.30)/3.92)
dim(erf) <- c(n, 1, 1)
dimnames(erf) <- list(obs=1:n, Outcome="Current asthma", "Age"="All")
erf <- as.data.frame(as.table(erf))

Result

{{#opasnet_base_link:Op_en4716}}
