Significats de reported tobacco en anglès

Conclusions: In smokers with HNSCC, self- reported tobacco use does not predict actual carcinogen exposure.

At both experimental sessions, self- reported tobacco withdrawal symptoms, affect, and smoking urge were assessed.

The primary outcome measures will include self- reported tobacco, alcohol, marijuana and other illicit drug use.

The misclassification rate among self- reported tobacco users was 1%.

Discussion: These findings suggest that self- reported tobacco use is a valid marker for tobacco exposure in the MoBa cohort.

Self- reported tobacco use (test variable) and plasma cotinine concentrations (gold standard) were assessed at approximately gestational week 18.

In a prospective cohort, self- reported tobacco use was assessed before starting ART and reassessed every 3-4 months.

Self- reported tobacco use among rural Ugandans starting ART was twice as common as among the local background population and use may be underreported.

Similar rates were observed in veterans who reported tobacco quit goal during treatment planning (37.4% to 56.8%).

Conclusions: To the best of our knowledge, this is the first time that the validity of the STEPS self- reported tobacco indicator has been tested.

We sought to examine the relationship between self- reported tobacco use and the level of urinary tobacco carcinogen metabolites in a cohort of patients with HNSCC.

Results: Among nonsmokers, all meconium specimens were negative, whereas nearly all meconium specimens were positive if the mother self- reported tobacco use into the third trimester.

Self- reported tobacco smoking, alcohol drinking, marijuana use, and hard illicit drug (cocaine, heroin, or methamphetamine) use were obtained at baseline and annual follow-up visits.

In this prospective study, we validated self- reported tobacco use against nicotine exposure assessed by plasma cotinine in the Norwegian Mother and Child Cohort Study (MoBa).
