Abstract
  • The effects of household exposure to cigarette smoke on the incidence of respiratory illness were examined among 1007 18 month old children at Lu-wan District, Shanghai City, People's Republic China. The passive smoking quantity was estimated by summing the total daily cigarette consumption of family members. No mothers who smoked were found. A significant dose-response relationship of passive smoking to hospitalization for respiratory illness during the children's first 18 months of life was found, for which no confounding factors were discovered. The relative risk was 2.4 for children living in families including people who smoked 20 or more cigarettes a day compared with those living in nonsmoking families. The children who were boys or artificially (bottle) fed were more affected than those who were girls or breast fed. The cumulative incidence of bronchitis and pneumonia increased significantly with increasing cigarette smoking of family members, that did not change when sex, birth weight, type of feeding, coal for cooking, or parental education were taken into account. Family smoking status was not found to be significantly associated with the cumulative incidence of asthma, whooping cough, sinusitis or measles.
