Abstract

MARTINEZ-SANCHEZ, José M et al. Validity of self-reported intensity of exposure to second-hand smoke at home against environmental and personal markers. Gac Sanit [online]. 2018, vol.32, n.4, pp.393-395.  Epub Dec 07, 2020. ISSN 0213-9111.  https://dx.doi.org/10.1016/j.gaceta.2017.08.002.

The objective of this study was to assess the validity of two questions about the perception of intensity of exposure to secondhand smoke (SHS) at home using as a reference environmental markers (airborne nicotine and benzene) and biomarkers of exposure (cotinine in saliva and urine). This was a cross-sectional study in a convenience sample of 49 non-smoking volunteers. We found a high correlation between self-reported SHS exposure and airborne nicotine (rsp= 0.806, p < 0.05), salivary cotinine (rsp= 0.752, p < 0.05), and urinary cotinine (rsp= 0.626, p < 0.05). We did not find differences between the score question and the conventional ones (p > 0.05). In conclusion, the significant correlation of the two questions proposed with environmental markers and personal markers indicates their potential validity to assess exposure to SHS at home.
