Validity of self-reported intensity of exposure to second-hand smoke at home against environmental and personal markers.
Gac Sanit . Jul-Aug 2018;32(4):393-395.
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.
