TASTE PERCEPTIONS AND DIETARY INTAKES OF SMOKELESS TOBACCO USERS AND NONTOBACCO USERS,

JOURNAL OF SENSORY STUDIES, Issue 3 2005
RHONDA A. SCHUELLER
ABSTRACT Smokeless tobacco and nontobacco users differed for certain concentrations of perceived intensities of the four solutions , significantly for sweet (P , 0.008) and salty (P = 0.001). Sensitivity to salty (P = 0.02) and bitter (P = 0.11) solutions decreased with increasing hours of exposure to smokeless tobacco. Smokeless tobacco and nontobacco users rated fruits and vegetables for preference and the four taste senses differently, with a decreasing trend for sweet tastes in smokeless tobacco users with increasing hours of exposure to smokeless tobacco. Smokeless tobacco users consumed more total fat (P = 0.06) and fat per 1000 kcal (P = 0.13) than nontobacco users. Higher intakes of total fat (P = 0.005), total fat per 1000 kcal (P = 0.18), total sodium (P = 0.03) and total Vitamin E (P = 0.06) were found with increasing hours of exposure to smokeless tobacco. Although fruit and vegetable intakes did not differ between smokeless tobacco and nontobacco users, both groups should increase their consumption of fruits and vegetables. [source]

Symptoms of nicotine dependence in a cohort of Swedish youths: a comparison between smokers, smokeless tobacco users and dual tobacco users

ADDICTION, Issue 4 2010

ABSTRACT Aims To determine whether symptoms of nicotine dependence, addiction and withdrawal symptoms differ between exclusive smokers, exclusive snus (moist snuff) users and dual users. Design A cross-sectional survey of a cohort subsample. Setting County of Stockholm, Sweden. Participants Current exclusive smokers (n = 466), exclusive snus users (n = 209) and dual users (n = 144), mean age 17.6 years. Measurements Self-reported life-time experience of nicotine dependence and withdrawal symptoms in periods of discontinued tobacco use. Selected items from the modified Fagerstöm Tolerance Questionnaire (mFTQ), the Hooked on Nicotine Checklist (HONC) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Findings The odds ratio of endorsing each of four mFTQ items as well as the HONC item investigating the risk of feeling addicted to tobacco was two to five-fold higher for exclusive snus users and for dual users compared to exclusive smokers. One DSM-IV item (difficult to refrain from use) was elevated among dual users compared to smokers. Dual users reported the highest prevalence of any withdrawal symptom in contrast to exclusive snus users, who reported a lower risk of withdrawal symptoms compared to exclusive smokers. Conclusions Smokeless tobacco users show symptoms of nicotine dependence at least as frequently as cigarette smokers. Symptoms of nicotine dependence and of withdrawal during quit attempts are particularly frequent in the subgroup of users who combine smokeless tobacco with smoking. [source]

Glutathione S -transferase M3 (A/A) genotype as a risk factor for oral cancer and leukoplakia among Indian tobacco smokers

Abstract Polymorphism in glutathione S -transferase (GST) genes, causing variations in enzyme activities, may influence susceptibility to oral cancer and leukoplakia in smokers and/or smokeless tobacco users. In this case-control study consisting of 109 leukoplakia and 256 oral cancer patients and 259 controls, genotype frequencies at GSTM1, GSTT1, GSTM3 and GSTP1 loci were determined by polymerase chain reaction-restriction fragment length polymorphism methods and analyzed by multiple logistic regression to determine the risks of the diseases. There were no significant differences in the distributions of GSTM1, GSTM3 and GSTT1 genotypes in patients and controls when all individuals were compared. In contrast, frequencies of ile/ile genotype at codon 105 and variant val-ala haplotype of GSTP1 was significantly higher (OR = 1.5; 95% CI = 1.0,2.0) and lower (OR = 1.4; 95% CI = 1.0,1.9) in oral cancer patients compare to controls, respectively. The impacts of all genotypes on risks of oral cancer and leukoplakia were also analyzed in patients with different tobacco habits and doses. Increased risks of cancer and leukoplakia were observed in tobacco smokers with GSTM3 (A/A) genotype (OR = 2.0, 95% CI = 1.0,4.0; OR = 2.0, 95% CI = 1.0,4.4, respectively). So, GSTM3 (A/A) genotype could become one of the markers to know which of the leukoplakia would be transformed into cancer. Heavy tobacco chewing (> 124 chewing-year) increased the risk of cancer in individuals with GSTT1 homozygous null genotype (OR = 3.0; 95% CI = 1.0,9.8). Furthermore, increased lifetime exposure to tobacco smoking (> 11.5 pack-year) increased the risk of leukoplakia in individuals with GSTM1 homozygous null genotype (OR = 2.4; 95% CI = 1.0,5.7). It may be suggested that polymorphisms in GSTP1, GSTM1, GSTM3 and GSTT1 genes regulate risk of cancer and leukoplakia differentially among different tobacco habituals. © 2003 Wiley-Liss, Inc.
