Two methods of identifying smokers with high nicotine dependence, the heaviness of smoking index (HSI) and number of cigarettes per day (CPD) were compared with the Fagerstrom test for nicotine dependence (FTND). The HSI, CPD and the FTND were administered to 316 adult Malaysian male, daily smokers aged between 25-64 years old in the Malaysian NCD Surveillance-1 Survey using a two-stage stratified random sampling of enumeration blocks and living quarters, via an interview based on a validated questionnaire. The cut-off point for classification of high nicotine dependence on the HSI was a score of four or higher, and for the heavy smoking category, smoking more than 20 cigarettes per day. Classification using each method was compared with classification by the FTND (score of six or more) as the reference standard. Sensitivity, specificity and kappa statistics for concordance between both measures and the FTND were evaluated. The HSI gave a similar prevalence rate of high nicotine dependence as the FTND. There was substantial agreement between the HSI and the FTND (kappa=0.63.), with moderate sensitivity (69.8%) and high specificity (92.5%). However, prevalence of high nicotine dependence using the CPD was 7% lower than the FTND. The heavy smoking category also showed fair agreement with the FTND (kappa=0.45) and moderate sensitivity (67.0%), but specificity was high (86.9%). The findings indicate that the HSI can be used as an alternative to the FTND in screening for high nicotine dependence among daily smokers in large population-based studies, while CPD may not be a suitable alternative to the FTND.

Purpose: The aim of this study was to investigate the risk of periodontitis according to current smoking status based on the number of cigarettes smoked per day (CPD) and the Fagerström Test for Nicotine Dependence (FTND). Methods: All enrolled patients were diagnosed and classified according to the new periodontal classification scheme, and current smoking status was investigated via a self-reported questionnaire. The correlation between smoking status (CPD and FTND) and periodontitis risk (severity of periodontitis and tooth loss due to periodontal reasons) was statistically assessed using Spearman correlation coefficients. Moreover, partial correlation analyses between smoking and periodontal status were performed after adjusting for age, sex, and diabetes mellitus. Results: Overall, data from 74 men and 16 women (mean age: 48.1±10.8 years) were evaluated. The mean number of missing teeth, CPD, and FTND score were 3.5±5.2, 24.6±15.5, and 3.5±2, respectively. CPD and the FTND were significantly positively correlated with each other (r=0.741, P<0.001). CPD and the FTND were also significantly correlated with the severity of periodontitis (CPD: r=0.457, P<0.05 and FTND: r=0.326, P<0.05) and the number of missing teeth due to periodontal reasons (CPD: r=0.525, P<0.05 and FTND: r=0.480, P<0.05), respectively. Conclusions: Within the limitations of this study, both CPD and the FTND were significantly correlated with the severity of periodontitis and the number of periodontally compromised extracted teeth.

Panning tasks caused by both a small screen and the lower resolution of handheld devices are known to decrease the usability of a mobile internet service. To solve this problem, we proposed FTND, an improved version of Tap-N-Drag widely used in various mobile web browsers. 30 participants performed the panning tasks with FTND embedded in combinations of 2 panning directions of Push Background user interface and Push Viewpoint user interface and 5 panning ratios of 100% (a panning ratio of Tap- N-Drag), 300%, 500%, 700%, and 900%. The usability of FTND was assessed by an objective performance and a subjective preference. The objective performance was measured by a task completion time, the number of clicks, and the number of pixels. The subjective preference was measured by satisfaction, accuracy and ease of use. Push Viewpoint user interface at the panning ratios of 300%, 500%, and 700% proved to be the most efficient way for panning tasks with small handheld devices when performing the task by using the right hand thumb.

Objectives : The purpose of this study is to investigate the practice level of Yangseng according to nicotine dependence. Methods : The subjects of this study were 137 male smokers in their thirties and forties, who visited Wonmi Public Health Center. They were evaluated with Fagerstorm's test for nicotine dependence (FTND) and Tool in Measuring Yangseng (TMY). By FTND score, they were divided into three groups; the mild nicotine dependent group, moderate group and severe group. Results : In TMY score, there were statistically significant differences in the characteristics of Diet, Activity & Rest, Sleep and total score among the three groups. The value of FTND comparing the values of Mind, Diet, Activity & Rest, Sleep and total score in this study resulted in negative correlations, which showed statistical significance. Conclusions : The above results suggest that there are significant relations between nicotine dependence and the practice level of Yangseng. These results can be used for planning a smoking cessation program and a Yangseng health promotion program based on Korean traditional medicine.

Objectives: An attempt was made to understand the nicotine dependence of smokers selected for an ongoing smoking cessation intervention programme in rural Kerala, India. Methods: Data were collected from resident males in the age group of 18 to 60 years from 4 randomly allocated community development blocks of rural Thiruvananthapuram district (2 intervention and 2 control groups). Trained accredited social health activist workers were utilised to collect data from all groups through face to face interview. Nicotine dependence among participants was assessed by means of the six-item Fagerstrom Test for Nicotine Dependence (FTND) translated into the local language. The internal consistency of FTND was computed using Cronbach's alpha coefficient. Criterion validity (concurrent) was assessed by correlations of nicotine dependence scores with age at initiation of smoking and cumulative smoking volume in pack-years. Results: Among the 928 smokers identified, 474 subjects were in the intervention area (mean age = 44.6 years, SD = 9.66 years) and 454 in the control area (mean age = 44.5 years, SD = 10.30 years). The overall FTND score among current daily smokers was 5.04 (SD: 5.05). FTND scores in the control and intervention areas were 4.75 (SD: 2.57) and 4.92 (SD: 2.51) respectively. The FTND scores increased with age and decreased with higher literacy and socioeconomic status. The average FTND score was high among smokers using both bidi and cigarettes (mean 6.10, SD 2.17). Internal consistency analysis yielded a Cronbach's alpha coefficient of 0.70 in a subsample of 150 subjects, a moderate result. The association of the scale was strongest, with the number of pack-years smoked (rho = 0.677, p < 0.001). Conclusion: A moderate level of nicotine dependence was observed among smokers in the current study. Tobacco cessation strategies could be made more cost effective and productive if a baseline assessment of nicotine dependence is completed before any intervention.

Objectives: The purpose of this study is to investigate the relationship of nicotine dependence and mental health. Methods: The subjects of this study were 153 male smokers in their 20s, 30s, 40s and 50s who visited Wonmi Public Health Center. They were evaluated with Fagerstorm's test for nicotine dependence (FTND) and Symptom Checklist-90-Revision (SCL-90-R). Using the FTND score, the participants were divided into three groups; mild nicotine dependent group, moderate group and severe group. Results: In the SCL-90-R score, there were statistically significant differences in the characteristics of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Global Severity Index (GSI) and Positive Symptom Test (PST) among the three groups. Comparing the values of FTND and the amounts of Daily Smoking to the values of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression and GSI in this study resulted in positive correlations, thereby demonstrating a statistical significance. Conclusions: The above results suggest that there are significant relations between nicotine dependence and the level of mental health. These results can be used for planning the smoking cessation program and mental health promoting program based on Korean traditional medicine.

이 연구의 목적은 대학생의 CIMT (목동맥 내막-중막 두께)와 흡연 습관, 음주 습관 및 두 가지 연관성을 조사하는 것이다. 이 연구는 CAGE (음주 관련: 절주, 비판에 대한 반감, 죄책감, 해장) 설문지, FTND (Fagerstrom Test for Nicotine Dependence) 설문지, 대학생들의 CIMT에 대하여 수행되었다. 세 군으로 분류 된 각 음주 수준에 따른 CIMT 결과 간에는 통계적으로 유의 한 차이가 없었다. FTND 흡연 분류에 따른 CIMT의 결과는 흡연 군이 비 흡연 군보다 높았다(P<0.01). 흡연과 음주는 좌우 CIMT 간에는 통계적으로 유의 한 차이가 있었다(P<0.01). 음주의 위험만 있는 군에서 왼쪽 CIMT (19.84 순위)는 낮은 순위를 보였다. 왼쪽(42.38 순위)과 오른쪽(42.81 순위)의 CIMT는 흡연 위험만 있는 집단에서 높은 순서를 보였다(P<0.01). 이 연구 결과 흡연자와 음주자 사이의 평균 CIMT, 특히 흡연 상태가 높은 사람들 사이에 뚜렷한 차이가 있음을 시사한다. 이 연구에는 몇 가지 제한 점이 있다. 첫째, 작은 연구 대상 두번째, 대상자가 어리고, 셋째, 흡연, 음주 및 CIMT에만 중점을 두었다. 결론적으로, 흡연은 젊은 성인에서 무증상 아테롬성 동맥 경화 위험인자에 대한 부작용과 CIMT를 현저하게 악화 시키며 젊은 성인에서 금연의 중요성이 강화되어야 한다.

Background: Although nicotine dependence plays a role as a main barrier for smoking cessation, there is still a lack of solid evidence on the validity of biomarkers to determine nicotine dependence in clinical settings. This study aimed to investigate whether urinary cotinine levels could reflect the severity of nicotine dependence in active smokers. Materials and Methods: Data regarding general characteristics and smoking status was collected using a self-administered smoking questionnaire. The Fagerstr$\ddot{o}$m test for nicotine dependence (FTND) was used to determine nicotine dependence of the participants, and a total of 381 participants were classified into 3 groups of nicotine dependence: low (n=205, 53.8%), moderate (n=127, 33.3%), and high dependence groups (n=49, 12.9%). Stepwise multiple linear regression model and receiver operating characteristic (ROC) curves analyses were used to determine the validity of urinary cotinine for high nicotine dependence. Results: In correlation analysis, urinary cotinine levels increased with FTND score (r=0.567, P<0.001). ROC curves analysis showed that urinary cotinine levels predicted the high-dependence group with reasonable accuracy (optimal cut-off value=1,000 ng/mL; AUC=0.82; P<0.001; sensitivity=71.4%; specificity=74.4%). In stepwise multiple regression analysis, the total smoking period (${\beta}$=0.042, P=0.001) and urinary cotinine levels (${\beta}$=0.234, P<0.001) were positively associated with nicotine dependence, whereas an inverse association was observed between highest education levels (>16 years) and nicotine dependence (${\beta}$=-0.573, P=0.034). Conclusions: The results of this study support the validity of using urinary cotinine levels for assessment of nicotine dependence in active smokers.

Purpose: To investigate the work associated stress and nicotine dependence among law enforcement personnel in Mangalore, India. Materials and Methods: A cross-sectional questionnaire survey was conducted among law enforcement personnel in Mangalore, India. Demographic details, stress factors experienced at work and nicotine dependency were the variables studied. The extent of stress factors experienced at work was assessed using the Effort-Reward Imbalance scale (ERI). Nicotine dependence was measured using the Fagerstrom Test for Nicotine Dependence (FTND) and the Fagerstrom Test for Nicotine Dependence-Smokeless Tobacco (FTND-ST). Logistic regression was used for the statistical analysis. Results: Three hundred and four law enforcement personnel participated in the study, among whom 68 had the presence of one or more habits like tobacco smoking, tobacco chewing and alcohol use. The mean effort score was $15.8{\pm}4.10$ and the mean reward and mean overcommitment scores were $36.4{\pm}7.09$ and $17.8{\pm}5.32$ respectively. Effort/Reward ratio for the total participants was 1.0073 and for those with nicotine habit was 1.0850. Results of our study demonstrated no significant association between domains of ERI scale and presence of habits but work associated stress was associated with the presence of one or more habits. Compared to constables, head constables had 1.12 times higher risk of having a nicotine habit. Conclusions: Our study implies job designation is associated with nicotine habits. However, there was no association between work associated stress and nicotine dependence among law enforcement personnel in Mangalore.

Purpose: A diverse range of measurement methods to evaluate the effect of smoking is more powerful than using a single measure. The objectives of this study were to examine the relationships among smoking pack year, self-reported smoking dependence, and urinary cotinine levels, and to investigate the psychological variables in working men. Method: In this cross-sectional study, we surveyed men working in an electronic company who participated in a smoking cessation program. Among 57 men who completed questionnaires, 25 participate in a test for cotinine levels. Results: Smoking pack year was significantly and positively correlated with the FTND-K (Korean version of Fagerstrom test for nicotine dependence) sum scores (r=0.631, p=0.000) and with the levels of urine cotinine (r=0.463, p=0.023). The relationship between FTND-K sum scores and urinary cotinine levels was also significantly positive (r=0.639, p=0.001). Those with higher social support, especially family support, tended to perceive a higher self-efficacy to smoking cessation. Conclusion: These findings suggest that self-reported smoking pack year and nicotine dependence in working men may be a valid way to evaluate the effect of smoking. A supportive family may influence smoking cessation in working men as it increases self-efficacy to avoid smoking.
