Validity of self-reported intensity of exposure to second-hand smoke at home against environmental and personal markers

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 cro...

description 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. Resumen: El objetivo de este trabajo es evaluar la validez de dos preguntas sobre la exposición al humo ambiental de tabaco (HAT) en el hogar utilizando como referencia marcadores ambientales (nicotina y bencenos en el aire) y biomarcadores específicos (cotinina en saliva y orina) de la exposición pasiva al tabaco. Para ello se realizó un estudio transversal de una muestra de conveniencia de 49 voluntarios no fumadores mayores de edad de la ciudad de Barcelona. Se encontró una alta correlación entre la pregunta de intensidad de la exposición pasiva autodeclarada en casa y la nicotina en el aire (rsp = 0,806, p < 0,05), la cotinina en saliva (rsp = 0,752, p < 0,05) y la cotinina en orina (rsp = 0,626, p < 0,05). No encontramos diferencias entre las preguntas puntuables y las convencionales (p >0,05). En conclusión, la alta correlación de las preguntas propuestas con los marcadores ambientales y los biomarcadores indica su validez para evaluar la intensidad de la exposición pasiva al tabaco en el hogar.
