DESIGN NARRATIVE
The analyses were directed at the following 1 Time spent in day-care and the incidence and severity of respiratory illnesses 2 Breast-feeding and the incidence and severity of respiratory illnesses during the first six months of life 3 Determinants of wheezing and wheezing illnesses 4 Determinants of a physician-diagnosis of asthma 5 Exposure to woodsmoke and incidence and severity of respiratory illnesses 6 Household demographics including ethnicity and incidence and severity of respiratory illnesses 7 Determinants of the duration of respiratory illnesses 8 The validity of retrospective parental reports of respiratory illness 9 Parental perceptions of the risks of indoor and outdoor air pollution 10 Clinical findings on assessment of ill children in the community
