Introduction: This study examined factors predicting nicotine withdrawal symptoms following quitting among Korean American smokers who were receiving counseling and nicotine replacement therapy. Methods: The sample comprised 90 Korean American smokers selected from a two-arm randomised controlled trial of a smoking cessation intervention (culturally adapted versus treatment as usual). Nicotine withdrawal symptoms were assessed weekly for the first four weeks from the target quit day, using the Minnesota Nicotine Withdrawal Scale (MNWS). Only those who participated in two or more weekly assessments of the symptoms were included. Results: Among the nine withdrawal symptoms listed in the MNWS, craving and disturbed sleep decreased over time whereas the remaining symptoms had no significant effect of time. Women or individuals who perceived greater risks of quitting smoking reported more withdrawal symptoms after controlling for abstinence status. Although withdrawal symptoms did not change, on average, with time, the rates of change varied randomly across individuals. Women reported more withdrawal symptoms in the first week after quitting and showed a higher rate of decline of the symptoms over time than men. Conclusions: Korean American smokers who are women or who perceive greater risks of quitting smoking may require more intensive treatment to effectively deal with post-quit withdrawal symptoms.

Korean men and women have the highest current smoking rates across all Asian ethnic subgroups in the United States. This is a 2-arm randomized controlled study of a culturally adapted smoking cessation intervention. The experimental condition received eight weekly 40-min individualized counseling sessions that incorporated Korean-specific cultural elements, whereas the control condition received eight weekly 10-min individualized counseling sessions that were not culturally adapted. All participants also received nicotine patches for 8 weeks. One-hundred nine Korean immigrants (91 men and 18 women) participated in the study. The rate of biochemically verified 12-month prolonged abstinence was significantly higher for the experimental condition than the control condition (38.2 vs. 11.1 %, χ ² = 10.7, p < 0.01). Perceived family norm significantly mediated the effect of cessation intervention on abstinence. Smoking cessation intervention for Korean Americans should be culturally adapted and involve family members to produce a long-term treatment effect.

This is the first study of Korean Americans’ smoking behavior using a topography device. Korean American men smoke at higher rates than the general U.S. population. Korean American and White men were compared based on standard tobacco assessment and smoking topography measures. They smoked their preferred brand of cigarettes ad libitum with a portable smoking topography device for 24 h. Compared to White men (N = 26), Korean American men (N = 27) were more likely to smoke low nicotine-yield cigarettes (p < 0.001) and have lower Fagerstrom nicotine dependence scores (p = 0.04). Koreans smoked fewer cigarettes with the device (p = 0.01) than Whites. Controlling for the number of cigarettes smoked, Koreans smoked with higher average puff flows (p = 0.05), greater peak puff flows (p = 0.02), and shorter interpuff intervals (p < 0.001) than Whites. Puff counts, puff volumes, and puff durations did not differ between the two groups. This study offers preliminary insight into unique smoking patterns among Korean American men who are likely to smoke low nicotine-yield cigarettes. We found that Korean American men compensated their lower number and low nicotine-yield cigarettes by smoking with greater puff flows and shorter interpuff intervals than White men, which may suggest exposures to similar amounts of nicotine and harmful tobacco toxins by both groups. Clinicians will need to consider in identifying and treating smokers in a mutually aggressive manner, irrespective of cigarette type and number of cigarette smoked per day.

Objective: This study examined gender, ethnicity and psychological factors associated with alcohol problems among Asian American college students, using the CAGE questionnaire. Method: The study is a cross-sectional, school-based survey. College students who self-identified as Asian, participated. Results: The sample comprised 258 Asian American college students (132 men and 126 women). In all, 17.7% of males and 8.9% of females had alcohol problems based on CAGE score of 2 or more; yet, the difference was marginally significant (χ² [1, N = 225] = 3.7, p = 0.08). Chinese and Vietnamese males tended to have more alcohol problems than females in their respective ethnic subgroups. Among Koreans, more females (33%) had the problems than males (11%). Male students did not differ in alcohol problems by ethnicity, whereas Korean females were more likely to have the problems (χ² [4, N = 112] = 13.0, p = 0.01) than females in the other groups. After controlling for gender, Asian American college students who were older (≥25), smoking currently and reporting depressed mood were more likely to have alcohol problems. Conclusions: College health center workers should monitor more closely Asian students who have the risk factors for early detection of and treatment for alcohol problems.

Introduction: This study was conducted to compare gender differences in the psychometric properties of the Fagerström Test for Nicotine Dependence (FTND). Methods: The sample comprised 334 Korean immigrants (97 women and 237 men) who reported daily smoking for the past 6 months. Item-by-item responses and exploratory factor analyses (EFA) were compared by gender. Promax rotation was selected based on findings from previous studies suggesting correlated factors. Results: Compared with men, women smoked fewer cigarettes per day, were more likely to smoke when ill in bed, and were less likely to smoke frequently in the morning. The entire sample and men within the sample had the same factor loading pattern, where three items (time to first cigarette, the cigarette most hate to give up, and smoke more frequently in the morning) were loaded on Factor 1 (morning smoking) and the remaining three items (difficult to refrain from smoking in public places, number of cigarettes smoked per day, and smoking even when ill in bed) on Factor 2 (daytime smoking). For women, however, neither the 1- nor 2-factor model fit the data well. Conclusions: For Korean American male smokers, the psychometric properties of the FTND were similar to those seen in other populations, but this was not the case with Korean American women. Clinicians may need to modify their interpretation of nicotine dependence severity if basing only on the FTND with Korean women. The FTND assesses smoking patterns which has a cultural influence and other measures of nicotine dependence should be considered.

The study was conducted (a) to assess use of any smoking cessation medications, (b) to identify factors associated with smoking, and (c) to assess knowledge of the health effects of smoking and attitudes toward smoking and seeking help for quitting among Vietnamese Americans. This is a descriptive study conducted with a nonrepresentative sample of 163 Vietnamese Americans. Current and former smokers constituted 24.4% and 25.6% of men and 1.2% and 3.5% of women, respectively. Of 20 current smokers, 17 (85%) reported use of cessation medications in their past quit attempts. Acculturation was the only significant correlate of ever smoking (vs. never smoking) in multivariate logistic regression analyses. Men who were less acculturated had more than 5 times the odds of being ever smokers (odds ratio = 5.33, 95% confidence interval = 1.37-20.78) compared with more acculturated men. Most participants had correct knowledge of the health effects of smoking regardless of age, education level, and smoking status. Attitudes toward smoking differed by age and education level but not by smoking status. Nurses working with Vietnamese Americans should be aware of the high rate of smoking among male immigrants and provide smoking cessation interventions.

Introduction: China has the highest number of tobacco smokers among the world’s nations; however, no systematic review has been conducted of clinical trials on the efficacy of smoking cessation interventions in China. This paper summarizes findings of studies in order to compare the effect of pharmacotherapy, counseling, and Traditional Chinese Medicine (TCM) approaches on the abstinence rate. Methods: Clinical trials of smoking cessation interventions published in English or Chinese were extracted from an electronic search of PubMed and WanFang databases. The search yielded 234 studies from the PubMed and 78 studies from the WanFang. Results: Twenty-nine studies were included in this review. Of these, 11 (37.9%) were randomized controlled trials (RCTs) that assessed the following approaches: counseling (5 studies), TCM (3 studies), pharmacotherapy (1 study), a combination of pharmacotherapy and counseling (1 study), and physician advice (1 study). Pharmacotherapy alone or in combination with counseling generally resulted in a higher abstinence rate than counseling alone. TCM techniques such as acupuncture and ear point seed pressure yielded a much higher abstinence rate than pharmacotherapy and counseling. Findings are inconclusive, however, because most of the TCM studies were noncontrolled trials and did not provide a definition of “abstinence.” Findings on the effectiveness of physician advice to quit smoking were also inconclusive. Conclusions: A review of smoking cessation studies revealed that pharmacotherapy was effective in China. More RCTs of TCM approaches and physician advice are needed with long-term follow-up assessments and biochemical verification of self-reported abstinence before these approaches are adopted as evidence-based smoking cessation interventions in China.

The study was conducted to examine the relative effectiveness of cognitive behavior therapy with a cultural tailoring intervention compared to brief medication management. The study used a two-arm randomized controlled trial in which participant assignment was stratified by gender. The intervention condition received eight weekly 40-min individualized counseling sessions of culturally tailored cognitive behavior therapy, while the control condition received eight weekly 10-min individualized counseling sessions of medication management. Both conditions received nicotine patches for 8 weeks. Data were collected at baseline and at four follow-up points (one and 4 weeks, and three and 6 months post-quit). Treatment outcomes were presented as an intention-to-treat analysis. Thirty Korean immigrants participated in the study. At 6-month follow-up, 57.1% of participants in the intervention and 18.8% of participants in the control had 7-day point prevalence abstinence (odds ratio = 5.8, 95% confidence interval = 1.12–26.04, P = 0.04). Participants’ self-reported abstinence was biochemically verified with exhaled carbon monoxide and salivary cotinine levels. A combination of the culturally tailored cognitive behavior therapy and nicotine replacement therapy had a better treatment outcome compared to brief medication management. The promising result suggests a need to further test the intervention in larger samples and longer follow-up assessments before it can be adapted in clinical settings.
