The purpose

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).
