Shown are odds ratios for asthma, OLS regression coefficients for height and standard errors. Note: Results for asthma were estimated using logistic regression. Results for height were estimated using OLS. Model 1 estimates the effect of infection burden on a health outcome, adjusting for age and gender. Model 2 adjusts for age, gender, race, education of the household head, family income, household size, region, and rural/urban classification. Model 3 estimates the effect of infection burden on a health outcome, net of the same set of predictors. Reference category for gender is male, and for race is non-Hispanic white. Infection burden was calculated using confirmatory factor analysis using the five individual infections and was standardized with a mean of zero and a variance of one.
