Abstract

Environmental Tobacco Smoke Exposure (ETS) is an issue at the forefront of Public Health research. A cohort study of Florida youth was assembled and followed. The study participants were identified using a probability sample. A sample of 1219 youth who reside in Florida were recruited to be members of the cohort. The study utilized both questionnaire and saliva cotinine measurements to identify critical predictors of ETS exposure in this population. The study then used the identified ETS predictors to screen the general population for ETS exposure. The data from this study confirm well established research findings that factors in the home are critical determinants of ETS exposure in children and adolescents. Living with an adult who smokes provides sufficient information to properly classify two-thirds of exposed children and adolescents from the general population into a high ETS exposure group. Furthermore, children who live with an adult who smokes inside the home are at highest risk for measurable ETS exposure. Living with an adult who smokes inside the home provides sufficient information to classify nearly 83% of exposed children and adolescents from the general population into high ETS exposure groups. The use of predictors to screen the general population for ETS exposure demonstrates the future utility of this study.This study was unable to identify critical predictors of ETS exposure among children and adolescents who do not live with an adult who smokes. The emphasis of future studies should be placed upon the design of a survey instrument that has the capability to assess external ETS exposures among children and adolescents who are not exposed to ETS in their homes. This will enable to identification of predictors that can then classify this group of individuals into low, intermediate and high-risk groups for ETS exposure.
