A home age stratified random sample cohort of 100 homes less than three years old and 37 homes of more than three years of age (mean 67 months) were enrolled and followed prospectively at monthly intervals. Formaldehyde air measurements ranged from below detection (0.1 ppm) to 2.84 ppm. The average monthly concentration from homes less than three years old was 0.54 ppm and 0.19 ppm from homes older than three years. Regression modeling found that the log of home age was the best environmental parameter for predicting formaldehyde levels. A total of 2,423 monthly self-administered symptom questionnaires were completed by the 288 persons in the homes which remained under study for six or more months. Stepwise logistic regression analysis was performed. A positive dependency of both burning eyes and watery eye symptom logits on the log formaldehyde exposure parameter was demonstrated. A positive relationship with respondents' age was also seen.
