650: Smoking during pregnancy as a possible risk factor for pediatric neoplasms in the offspring: A population-based cohort study Academic Article uri icon

The potential long-term effect of intrauterine exposures on offspring's health is of major interest. We aimed to evaluate the effect of maternal smoking during pregnancy on the long-term risk for pediatric neoplasms in the offspring.

Pediatric neoplasms were pre-defined based on ICD-9 codes, as recorded in the hospital computerized medical files.
