Exposure to secondhand smoke is a leading preventable cause of child morbidity and mortality,
and the adverse health consequences of secondhand smoke are magnified among youngsters with
cancer and sickle cell disease. Current methods for measuring secondhand smoke exposure
(SHSe) rely on retrospective reports over extended time periods that are subject to recall
errors and systematic inaccuracies in reporting and often do not include the youngster as the
primary informant. These methods may underestimate the extent of cumulative SHSe and are not
well suited to capturing exposure over time and across settings where young people frequent.
More appealing methods that engage youngsters to better monitor tobacco smoke in their
environment are warranted.
The study will examine the feasibility of cell phone texting to obtain measures of secondhand
smoke exposure (SHSe) in children treated for cancer or sickle cell disease (SCD).
