Nicotine dependence as a risk factor for upper aerodigestive tract (UADT) cancers: A mediation analysis.

What Was Tested

This observational study looks at Therapeutic nicotine (patch, non-peptide).

This study investigated nicotine dependence as an independent risk factor for upper aerodigestive tract (UADT) cancers, including lung and head and neck cancers (HNC).

The study aimed to isolate the direct effect of nicotine dependence, independent of tobacco smoking.

Who Took Part

According to the abstract, 4957 participants were involved.

PubMed indexes the participants as middle-aged adults and older adults, both men and women.

A case-control study with a total of 4957 participants was conducted in Ontario, Canada, of which 2964 categorized as either current or former smokers were used in the analysis.

How the Study Was Run

Nicotine dependence of ever-smokers (2360 UADT cases and 604 controls) was measured using the Fagerström Test for Nicotine Dependence.

Using mediation analyses and adjusted logistic regression models, the researchers decomposed the direct effect of nicotine dependence and the mediated effect of smoking duration to quantify the risks of lung and HNC.

The role of human papillomavirus (HPV) and cancer subtypes were assessed.

What Was Measured

The subject headings attached to it are Case-Control Studies, Head and Neck Neoplasms, Lung Neoplasms, Nicotine, Ontario, Risk Assessment and Risk Factors.

What This Means in Plain Language

This is an observational study of Therapeutic nicotine (patch, non-peptide) in 4957 participants.

With several hundred people or more, it is a fairly large study for this kind of research.

Results are reported in around 6 sentences of the abstract; we leave them to the paper itself rather than summarise them.

The publication is from 2020 (PloS one), a journal based in United States.
