Abstract

Background: Recognizing the suboptimal public health effects of a complete cessation strategy for parents and child caregivers who smoke, some researchers have called for a harm reduction approach; however, the evidence remains scanty and controversial. Objective: To examine the effects of secondhand smoke and smoking hygiene on infant health and related health care costs during the first 18 months of life. Methods: We conducted prospective follow-up on 8327 newborns during April and May of 1997 for 18 months in a population-based birth cohort of infants from Hong Kong, China. Main Outcome Measures: Number of hospital admissions, adjusted odds ratios for ever hospitalization for each secondhand smoke exposure variable, and corresponding population attributable risks. Results: Most secondhand smoke exposure came from fathers and other household contacts, whereas only 2.8% of mothers smoked postpartum. The odds ratio of ever hospitalization due to all illnesses combined for infants living in a household with any (maternal, paternal, or other) smoker who was smoking at least 3 m away from the infant, as reported by a parent, was 1.00 (95% confidence interval, 0.88-1.13) compared with those in a smoke-free household. The corresponding odds ratio for infants living with any smoker at home with poor smoking hygiene (
