Association between serum cotinine and learning disability in children aged 4–15 years: A secondary data analysis from the NHANES dataset [PDF]

Tobacco Induced Diseases
Introduction While prior studies suggest links between secondhand smoke (SHS) exposure and developmental impairment, evidence linking objective biomarkers of SHS exposure to learning disability (LD) in children remains limited.

Exploring the associations of tobacco smoking and serum cotinine levels with selected inflammatory markers in adults with HIV in South Africa [PDF]

Scientific Reports
This study examined the associations between tobacco smoking and serum cotinine levels, an objective biochemical measure of tobacco smoke exposure, with markers of inflammation, i.e., interferon-gamma (IFN-γ), interleukin 10 (IL-10), interleukin 2 (IL-2)

Relation of Serum Cotinine with Passive Smoking

Pakistan Journal of Medicine and Dentistry
Background: Cotinine is a major metabolite of nicotine and retains for a substantial time in different body fluids. It is considered as a passive smoke exposure marker. Studies on different biochemical markers of tobacco smoke exposure are lacking in

Toward improved statistical methods for analyzing Cotinine-Biomarker health association data [PDF]

Tobacco Induced Diseases, 2011
Background Serum cotinine, a metabolite of nicotine, is frequently used in research as a biomarker of recent tobacco smoke exposure. Historically, secondhand smoke (SHS) research uses suboptimal statistical methods due to censored serum cotinine values ...

Estimation of level of serum cotinine: A simple, rapid and sensitive biomarker in cigarette smokers

Asian Journal of Medical Sciences
Background: Cigarette smoking remains the leading preventable cause of morbidity and mortality worldwide. Cotinine, a metabolite of nicotine, serves as a reliable biomarker of tobacco exposure due to its longer half-life (18–20 h) compared to nicotine (2–
