Reliance upon caregiver report of their child\u2019s environmental tobacco smoke (ETS) exposure may result in information bias and impaired asthma management. This analysis aimed to characterize the chronicity of ETS exposure, assess the validity of caregiver report of ETS exposure, and investigate the relationship between ETS exposure and asthma attack.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2059866124005818_as2\">\n\t    <jats:title>Methods:<\/jats:title>\n\t    <jats:p>A secondary data analysis was performed on data from a longitudinal study of 162 children aged 7\u201312 years with asthma living in federally subsidized housing in three US cities (Boston, Cincinnati, and New Orleans). Data were collected at three time points over 1 year.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2059866124005818_as3\">\n\t    <jats:title>Results:<\/jats:title>\n\t    <jats:p>Over 90% of children were exposed to ETS (\u22650.25 ng\/ml of urine cotinine (UC)). Exposure was consistent over 1 year. Questionnaire data had a sensitivity of 28\u201334% using UC \u22650.25 ng\/ml as the gold standard. High ETS exposure (UC \u2265 30 ng\/ml) was significantly associated with asthma attack (aOR 2.97, 0.93\u20139.52, <jats:italic>p<\/jats:italic> = 0.07). Lower levels (UC 0.25\u201330 ng\/ml) were not statistically significant (aOR 1.76, 0.71\u2013 4.38, <jats:italic>p<\/jats:italic> = 0.22). No association was found using caregiver-reported ETS exposure.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2059866124005818_as4\">\n\t    <jats:title>Conclusion:<\/jats:title>\n\t    <jats:p>Relying on questionnaire data to assess children\u2019s exposure to tobacco smoke may lead to substantial information bias.
