We evaluated a new cotinine test strip to assess smoking status. Urine cotinine was measured using cotinine test strips and also by gas chromatographic techniques (GC) (as the reference criterion). Smoking status was assessed with a self-administered questionnaire. The cotinine test strip identified smokers with a very high level of agreement (97.3% using 100 ng/ml and 97.1% using 250 ng/ml for the cutoff point) and non-smokers with a fair-to-moderate level of agreement (74.5% using 100 ng/ml and 86.4% using 250 ng/ml for the cutoff point). These data suggest that the cotinine test strip appears to provide a reasonably accurate measure of smoking status. Since this was the first study to evaluate the cotinine test strip using the test strip prototype, larger clinical trials are needed to evaluate the validity of the cotinine test strip compared to GC measurements to confirm smoking status.

Association between smoking status and health-related quality of life: a study on differences among age groups.
Front Public Health
January 2025
HEOA Group, School of Public Health, Chengdu University of Traditional Chinese Medicine, Chengdu, China.
Purpose: This study explored the effect of four different smoking statuses (non-smokers, moderate smokers, heavy smokers, and former smokers) on health-related quality of life (HRQOL) among residents aged 15 years and older in Sichuan Province, China with consideration of potential differences among age groups (young, middle-aged, and older adults).
Methods: The EQ-5D-5L utility index and EQ-VAS score were used to measure HRQOL. Self-reporting and salivary cotinine test were used to determine the smoking status of respondents, and the Tobit regression model was used to explore the relationship between smoking status and HRQOL.
Efficacy of shared decision making in tobacco cessation among health facilities of Haryana, India - A double blinded, parallel group Randomized Controlled trial Protocol.
Public Health Pract (Oxf)
June 2025
Department of Psychiatry, Post Graduate Institute of Medical Education and Research, Chandigarh, 160012, India.
Background: Shared decision-making (SDM) incorporates evidence, patient values, and preferences into medical decision-making. SDM and decision aids might promote health professional engagement and patient knowledge of tobacco cessation therapy, improving usage and results. The SDM facilitates talks that lead to better-informed judgements that align with patients' priorities, unlike individual decision-making.

Background: Previous research has indicated a potential connection between smoking and tooth loss, but it remains unclear how the metabolites of nicotine, cotinine (COT) and trans-3'-hydroxycotinine (HC), and the nicotine metabolite ratio (NMR) affect the occurrence and progress of tooth loss. In this study, we aimed to investigate the relationship between tooth loss and smoking metabolites, then verify how the systemic immunoinflammatory index (SII) or monocyte to high-density lipoprotein cholesterol ratio (MHR) levels mediate this process.
Methods: The cross-sectional study data were collected from the National Health and Nutrition Examination Survey (NHANES).

Article Synopsis
- Residential smoking cessation therapy can significantly aid heavy smokers, especially those with high dependence and health issues needing immediate intervention.
- Changes in participants' thoughts and feelings about smoking during therapy relate to their success in quitting, with factors like age and coping strategies playing a key role.
- Successful quitters tended to have better emotion regulation strategies and a stronger negative perception of smoking's effects, indicating these psychological aspects are critical to cessation outcomes.
