No published studies have prospectively evaluated the association between urinary 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) levels and lung cancer risk in the general population. Here, we conducted a prospective community-based cohort study in the Republic of Korea to evaluate the relationship between urinary NNAL levels and lung cancer risk using prediagnostic urine samples. This prospective cohort study was based on the Korean National Cancer Center Community Cohort. During the follow-up period, 173 primary lung cancer cases were identified. Total urinary NNAL levels were measured by liquid chromatography-tandem mass spectrometry, and data were analyzed using multivariable Cox proportional hazards regression models. The risk of lung cancer was significantly increased per unit of natural log-transformed urinary NNAL (HR, 1.27; 95% CI, 1.09–1.48), after adjusting for age, region, entry year into the cohort, education achievement, alcohol consumption status, BMI, smoking status, and urinary cotinine levels. Cox proportional-hazards models with NNAL quartiles also showed positive dose-response relationships with risk of lung cancer. A significantly increased risk of lung cancer was found in the fourth quartile of urinary NNAL levels (HR, 3.27; 95% CI, 1.37–7.79, P for trend < 0.01). After stratification with sex, the significant association remained in only men. Urinary NNAL levels are associated with the risk of lung cancer in the general population, and this association is independent from the quantification of cigarette smoking and nicotine uptake.

Recent prospective cohort studies have suggested that circulating persistent organic pollutants (POPs) may be associated with the development of cancers. We investigated the association between pre-diagnostic serum concentrations of POPs and colorectal cancer (CRC) risk. A case-cohort study within a community-based prospective cohort was performed, including 104 CRC cases and 235 subcohort participants. Serum concentrations of POPs were measured by high resolution gas chromatography/high-resolution mass spectrometry. Multivariable Cox proportional hazards regression models were used. The association between serum concentrations of organochlorine pesticides (OCs) and CRC risk was significant (cis-heptachlor epoxide: 3rd tercile [HR (95% CI): 2.76 (1.25–6.07); trans-nonachlor: 2nd tercile [HR (95% CI): 3.90 (1.56–9.75)], 3rd tercile [HR (95% CI): 4.86 (1.95–12.16)]); p,p’-DDD: 2nd tercile [HR (95% CI): 6.02 (2.05–17.70)], 3rd tercile [HR (95% CI): 7.43 (2.42–22.84)]). Certain polychlorinated biphenyls (PCBs) congeners were significantly associated with CRC risk (PCB-105: 3rd tercile HR [95% CI]: 3.15 [1.38–7.19], PCB-118: 3rd tercile HR [95% CI]: 2.68 [1.22–5.92]; PCB-138: 2nd tercile [HR (95% CI): 2.51 (1.19–5.28)], 3rd tercile [HR (95% CI): 3.27 (1.50–7.12)]; PCB-153: 2nd tercile [HR (95% CI): 3.93 (1.81–8.54)], 3rd tercile [HR (95% CI): 5.02 (2.09–12.07)]; PCB-156: 2nd tercile [HR (95% CI): 2.61 (1.21–5.59)], 3rd tercile [HR (95% CI): 4.07 (1.73–9.61)]; PCB-180: 2nd tercile [HR (95% CI): 2.58 (1.15–5.78)], 3rd tercile [HR (95% CI): 4.01 (1.68–9.59)]).results This study suggests that serum concentrations of POPs could increase the CRC risk in the general population.

Background: The popularity of heated tobacco products (HTPs) has been growing globally but, limited information exists on tobacco use behaviors and its impact on tobacco control. This study investigates awareness and perception of HTPs among tobacco users, and whether perceptions of HTPs are associated with HTP use and intention to quit. Methods: 2,000 tobacco users aged 19–65 years with countrywide representation were invited to an online survey in November 2018. Information on general characteristics, tobacco use behaviors, awareness and perception of HTPs, and intention to quit, were gathered. Multinomial logistic regression analysis and ANCOVA were used for estimation of association and comparison. Results: Among all tobacco users, 36.8% were classified as ever users, whereas 28.3% had used HTPs in the past 30 days, which was higher than expected. Users of liquid-based e-cigarettes (OR: 1.578; CI: 1.210–2.056) and poly product (OR: 2.029; CI: 1.121–3.671) showed higher intention to quit within 1 month when compared to users of conventional cigarettes (CCs), whereas HTP users and dual product users did not. HTP users rated HTPs more favorably than CCs in terms of smoke, smell, harm, aid in quitting, design, and price than users of other products did (p-value <0.001). Conclusions: We find that positive perception of HTPs following strategic marketing from tobacco companies could have contributed to an increase in HTP use than expected in Korea. However, HTPs might not be considered substitutes for CCs for quitting tobacco use because a significant proportion of dual product users reported a lower intention to quit.

OBJECTIVES: This study was performed to identify the effect of physical activity at work on obesity and to analyze the contribution of socioeconomic factors and health behaviors to this association, which has been relatively little studied.METHODS: From the Korean National Cancer Center Community Cohort, a total of 5,587 adults (2,125 men; 3,462 women) aged more than 30 years living in rural areas were enrolled. Information on socio-demographic factors, health behaviors, and body mass index was gathered using face-to-face interviews and measurements of height and weight.RESULTS: Inverse associations were identified between vigorous-intensity physical activity at work and obesity in both men and women, while no association was found between vigorous-intensity physical activity during leisure time and obesity. High household income was independently associated with a lower risk of obesity among those who had low levels of vigorous-intensity physical activity at work. Vigorous physical activity at work showed an inverse association with obesity in rural areas where heavy manual labor is common.CONCLUSIONS: Our findings indicate the necessity to account for various types of physical activity to improve the assessment and prevention of obesity.

Background: This study aimed to determine the effects of metabolic syndrome (MetS) on colorectal cancer (CRC) using propensity score (PS) methods. Methods: The study subjects were 2417 men and 4568 women from the Korean National Cancer Center (KNCC) Community Cohort enrolled between 2003 and 2010. Odds risks (ORs) and 95% confidence intervals (CIs) using PS matching analysis, regression models adjusted by the PS or stratified into five strata according to PS, and PS weighting methods were calculated. Results: In women, MetS and abnormally high triglyceride (TG) levels were associated with CRC risk using the PS matching analysis (ORs, for MetS, 2.19 (95% CI, 1.10–4.33); for abnormal TG levels, 2.08 (95% CI, 1.07–4.02)). However, there were no significant associations between MetS and TG levels and CRC risk in men. Conclusions: Our study might provide additional evidence that deteriorated metabolic profiles increase the risk of CRC in women rather than men. Thus, this may have an important role in effective population-level interventions for deteriorated metabolic profiles at an early stage.

Since the global enforcement of smoke-free policies, indoor smoking has decreased significantly, and the characteristics of non-smokers’ exposure to secondhand smoke (SHS) has changed. The purpose of this study was to assess the temporal and spatial characteristics of SHS exposure in non-smokers by combining questionnaires and biomarkers with time activity patterns. To assess SHS exposure, biomarkers such as cotinine and 4-(methylnitrosamino)-1-3-(pyridyl)-1-butanol (NNAL) in urine and nicotine in hair were collected from 100 non-smokers in Seoul. Questionnaires about SHS exposure and time activity patterns were also obtained from the participants. The analysis of biomarker samples indicated that about 10% of participants were exposed to SHS when compared with the criteria from previous studies. However, 97% of the participants reported that they were exposed to SHS at least once weekly. The participants were most exposed to SHS in the outdoor microenvironment, where they spent approximately 1.2 h daily. There was a significant correlation between the participants’ time spent outdoors and self-reported SHS exposure time (r2 = 0.935). In this study, a methodology using time activity patterns to assess temporal and spatial characteristics of SHS exposure was suggested. The results of this study may help develop policies for managing SHS exposure, considering the time activity patterns.

The aim of this study was to evaluate the effect of additional motivational enhancement through telephone-based counseling on short- and long-term smoking abstinence among Korean adolescents. Methods: A comparative retrospective study was conducted based on the longitudinal follow up in Quitline from 2010 to 2017. A total of 533 and 178 adolescent smokers voluntarily participated in the 1-year quitting counseling only (group A, who were ready to quit) and the additional 4-week motivational interviewing before 1-year quitting counseling (group B, who were ambivalent about quitting), respectively. The outcomes were self-reported continuous abstinence at 30-day, 6-month, and 1-year follow up. Logistic regression was applied to estimate the effect of potential factors, including motivational enhancement, on cessation outcome. Results: At baseline, adolescents in group B had a lower motivation to quit than those in group A (p < 0.001). The successful quit rates at 30-day, 6-month, and 1-year follow up were 37.2%, 12.8%, and 11.4% in group A and 33.7%, 15.2%, and 11.2% in group B, respectively. After adjusting factors as appropriate, successful quit rates in group B were not significantly different from the rates in group A. Higher self-efficacy increased the successful quit rate at 30-day, 6-month, and 1-year follow up, similar in subgroup analysis by gender. Never-drinking showed significant association with 30-day successful quit in the whole population and among boys. The lower number of smoking triggers was associated with an increased 30-day successful quit rate among boys only. Conclusions: Counseling for motivational enhancement could be a promising approach for better quitting outcomes. Improving self-efficacy and eliminating smoking triggers should be continuously strengthened during the quitting process.

The prevalence of stress and distress has been increasing and being important public health issues; nevertheless, few studies have assessed the factors associated at the population level. This study identified factors associated and how they differentially influence stress and distress. A total of 35,105 individuals aged 19 years and older using nationally representative data from the Korea National Health and Nutrition Examination Survey (2007–2012) were included in the study. Subjects were differentiated by gender and psychological state (no symptoms, stress, distress). The associations of socio-demographics, psychosocial factors, health behaviours, and chronic illness with psychological states were analysed by gender. Socio-demographics and psychosocial factors such as lower household income, lower education level, living alone or negative outcome of marriage, and unemployment were associated with distress in both genders. Male and female educated higher and with short sleep duration, male living alone and with higher household income, and female married and with a lower household income was associated with stress. A perceived body image of slim or fat was associated with distress and stress in both genders. Behavioural factors, such as smoking, higher alcohol consumption, and abnormal calorie intake, were associated with stress and distress in both genders, with the exception of alcohol consumption in distress and abnormal calorie intake in stress of male. Socio-economic deprivation and negative psychosocial and behavioural factors were differently associated with psychological distress or stress by gender. Intervention strategies for distress and stress should be specifically tailored regarding these differences.

Recent studies suggest that high pre-diagnostic serum concentrations of persistent organic pollutants (POPs) might result in the development of cancers in the general population. However, the association between pre-diagnostic serum POP concentrations and lung cancer risk has not been studied. Here, we evaluated associations between low-dose environmental exposure to POPs and risk of lung cancer using pre-diagnostic serum samples in a case-cohort study based on a population-based prospective cohort. We conducted a case-cohort study based on the Korean National Cancer Center Community Cohort, from which we included 118 lung cancer cases and 252 controls. Serum concentrations of POPs were measured by high resolution gas chromatography/high-resolution mass spectrometry, and data were analyzed using multivariable Cox proportional-hazards regression models. Risk of lung cancer increased per unit increase in the natural log-transformed concentrations of the sum of chlordane congeners, total PCBs, and all PCBs subgrouped by the number of chlorines or ortho- substituted chlorines on the molecules, except for tri/tetrachlorobiphenyls, in all models. Among individual POP analytes with a detection rate >80%, after Bonferroni adjustment, only trans-nonachlor was associated with lung cancer risk. In categorical models, risk of lung cancer was associated with serum concentration of chlordane (4th vs. 1st quartile, hazard ratio [95% confidence interval], 8.79 [2.77–27.97]). Dose-dependent relationships were also found between risk of lung cancer and serum concentrations of PCBs regardless of their degree of chlorination, substitution pattern, or binding affinity to receptors (total PCBs, P = 0.002; mid-chlorinated PCBs, P = 0.004; high-chlorinated PCBs, P < 0.001; non- and mono-ortho PCBs, P = 0.031; di-ortho PCBs, P = 0.003; PCBs with dioxin-like activity, P = 0.011; non-dioxin-like non-/mono-ortho PCBs, P = 0.060). Serum concentrations of chlordane and PCBs are associated with risk of lung cancer in the general population, even decades after the ban on their production and use.

Aims It is not known whether the machine‐smoked nicotine yield of usual brand of cigarette smoked is associated with the chances of success of quit attempts. This study aimed to assess this association. Design Prospective study. Setting Republic of Korea. Participants A total of 16,808 male smokers registered for the Quitline between April 7, 2006 and December 31, 2013. Of these, 13,176 participants who were >19 years of age and provided data on their demographic characteristics, smoking‐related behaviors, nicotine dependence, tobacco brands used, and self‐efficacy were included in this study. Measurements Machine‐smoked nicotine yield was based on information provided by tobacco companies on cigarette packages that smokers reported as their usual brand. Ultra‐low nicotine yield was defined as ≤0.1 mg machine‐smoked nicotine yield per cigarette, whereas higher nicotine yield was defined as >0.1 mg machine‐smoked nicotine yield. Participant personal information and self‐reported continuous abstinence at 1‐month, 6‐month, and 1‐year follow up were recorded in electronic databases. Findings Continuous abstinence rates in the ultra‐low nicotine yield vs. higher nicotine yield groups were (respectively): 40.7% vs. 34.6% at 1 month (OR 1.22, 95%CI 1.12–1.33) 22.7% vs. 18.8% at 6 months (OR 1.20, 95%CI 1.08–1.32), and 19.5% vs. 16.6% (1.19, 95%CI 1.10–1.29) at 1 year. The association between ultra‐low nicotine yield cigarette smoking and successful quitting was stronger among the smokers with higher cigarette dependence. Conclusions Male smokers who use the Korean Quitline are more likely to quit successfully if they smoke ultra‐low nicotine yield cigarettes than if they smoke higher nicotine yield cigarettes.

We analyzed data from the Korean Youth Risk Behavior Web-based Survey (N = 68 043), a nationally representative survey, to examine the association between early initiation of smoking, alcohol drinking, and sexual activity and socioeconomic determinants among adolescents. The prevalence rates of early initiation of smoking (i.e, starting at age 12 years or younger), alcohol drinking, and sexual activity were 4.8%, 10.3%, and 1.4%, respectively. Adolescents with a low level of perceived household income, low level of father’s education, and those living without family were more likely to start these risky behaviors early. Early initiation of smoking was significantly affected by affordability.

While tobacco control policies have been adopted and enforced, and anti-smoking campaigns have been conducted, the evaluation of their impact on tobacco quitting is lacking in Korea. Therefore, the effectiveness of tobacco control policies and mass media campaigns to encourage use of the Quitline were evaluated by monitoring call volume on Quitline, which has been in operation since 2006, in Korea. Tobacco control policies and mass media campaigns, from 1 January of 2007 to 31 December of 2016, were assessed from the review of government documents and the history of law and regulation changes. The corresponding period incoming call volumes of the Quitline were assesed. The average monthly call volume, when policies and anti-smoking advertising were implemented, was compared with that of the whole year or baseline years (2007 and 2008). Peak call volume occurred in 2010 when the Quitline was directly promoted on television. The call volume in the month the TV campaign aired was 5.5 times higher than the average monthly call volume in the year 2010. A relatively gradual rise in call volume was found from 2013 to 2016 when the tobacco control policies and campaigns, such as Quitline number included on cigarette packs, a fear-oriented anti-tobacco campaign on mass media, and a tax increase on tobacco was implemented, were introduced sequentially. In that period, the average monthly call volume was about five times higher than in 2007 and 2008. Continuous efforts to contribute to tobacco control policies and campaigns by the promotion of the Quitline is a most effective approach to raise quitting attempts. Based on the Korean experience, Quitline data may be useful for assessing the impact of tobacco control policies and campaigns in Asian Pacific countries.

Introduction Raising the price of cigarettes is one of the most effective strategies to reduce cigarette smoking. The Vietnamese government is working toward the tobacco control goal of a 10% reduction in smoking prevalence by 2020. However, cigarette prices in Vietnam have not increased in the last two decades. The aim of this study was to estimate what cigarette prices would make smokers attempt to quit smoking, and to identify predictors of the price to quit and the intention to quit. Methods A cross-sectional survey was conducted with 822 male current smokers in Da Nang, Vietnam. A structured questionnaire was adapted from the International Tobacco Control project survey. Bayesian quantile regression was applied to predict factors associated with expected cigarette price. Results Fifty-six percent of smokers suggested a price to quit. Their median suggested price to quit per pack, 62 000 VND (2.8 USD), was 2.8 times higher than the actual current price, 22 000 VND (1.01 USD). Suggesting a lower price to quit was significantly associated with awareness of warning labels and smoke-free policies. In contrast, being a heavy smoker was significantly associated with a higher suggested price to quit across all quantiles. Conclusions There may be sufficient room to increase cigarette prices in Vietnam. The price to quit is associated with various factors, including non-pricing policies. Implications Evidence suggests that a steep increase in cigarette prices, setting a high minimum tax, and introducing a large specific tax, which are policy-induced price increases that can raise prices substantially in Vietnam, are preferable strategies. In addition to increasing price and taxes, the government should also strengthen non-pricing policies.

Relatively little is known about which characteristics of smokers are related to choosing a specific type of smoking cessation service. The user characteristics of different smoking cessation services were compared to determine the service preferred by user characteristics. The characteristics of adult smokers from Korea National Health and Nutrition Examination Survey (3762) and registered users of national smoking cessation services operated through the web (14,762), at Public Health Center-based Smoking Cessation Clinics (PHC-based SCCs) (335,532), and by telephone (Quitline) (2983) were compared. Females and younger aged were more in web and telephone-based cessation service users, while aged 50 years or older were more in PHC-based SCCs users. Although manufacturing and production workers were the most prevalent among smokers in the general population, office workers and others including housewives and unemployed were most prevalent among the users of Quitline and PHC-based SCCs, respectively. The number of cigarettes smoked per day was twice as high among cessation service users as in general population. Smokers with greater nicotine dependency were most prevalent in the web-based service. Overseas users were in the web-based cessation service. Identifying user-specific characteristics by the type of cessation services looks necessary to develop and offer appropriate cessation services.

To compare the prevalence of metabolic syndrome (MeS) in cancer survivors returning to the community to that of non-cancer controls. We used baseline data from a nationwide cohort study. 5274 cancer survivors and 20,703 and 21,096 gender- and age-matched controls without and with chronic disease was included. The prevalence of MeS was higher in cancer survivors compared to controls without chronic disease, but was lower than that in controls with chronic disease (25.7%, 18.8%, and 32.0%, respectively). The prevalence was 1.56-fold higher in cancer survivors (95% confidence interval = 1.45–1.69) than in controls without chronic disease. The prevalence of each MeS component was significantly higher in cancer survivors compared to controls without chronic disease. Compared to controls, the prevalence was higher in colorectal, breast, cervical, lung, thyroid, prostate, and bladder cancer survivors (OR range = 1.63–2.24, P-value < 0.05), but not in gastric and liver cancer survivors. MeS was generally more prevalent among cancer survivors than in controls without chronic disease, but with heterogeneities in cancer type. Because long-term care and comorbidity prevention are emerging issues in cancer survivors, MeS among those returning to normal life is concerning, and tailored management programs should be developed for specific cancer types.

High-risk human papillomavirus (HPV) infection progression should be considered a critical factor for preventing cervical cancer, although most infections are transient and rarely persist. This study aimed to examine the specific types of HPV infections, their change patterns, and the potential risk factors among Korean women. We included 4,588 women who visited hospitals in Busan and Suwon for cervical cancer screening, and 1,224 of thesewomen attended a 2-yearfollow-up. Infection statuswas evaluated using HPV DNA testing (Hybrid Capture 2) and genotyping testing (Linear Array). Data regarding the potential risk factors for HPV infection were collected by trained nurses using structured questionnaires. Among the 1,224 women (mean age, 47 years), 105 women (8.6%) were HPV-positive at baseline. HPV infections had been cleared among 92 women (87.6%) within 2 years. Only 13 infections (12.4%) were remained, and the 10 cases of them are high-risk HPV types including genotype 33, 45, 16, 35, and 52. Among women who were negative at baseline, the HPV incidence was 4.8%. The HPV incidence was marginally associated with having multiple sexual partners (odds ratio, 2.0; 95% confidence interval, 1.0 to 3.9), although it was not significantly associated with HPV persistence. Most HPV infections (88%) among Korean women were cleared within 2 years, with only a small number of persistent infections. The persistent HPV genotypes were different in our study, compared to those from previous studies. Having multiple sexual partners was associated with acquiring a HPV infection, but not with persistence.

Human papillomavirus (HPV) vaccination has been included in the National Immunization Program in Korea since 2016. We aimed to evaluate changes in the awareness of and attitudes toward HPV vaccination, among adults in Korea since the first introduction of the vaccines in 2007. A nationwide population-based survey was conducted in 2016 for 1,200 nationally representative Korean men and women; the data obtained were compared with the data from the nationwide survey conducted in 2007. A significant increase in the awareness of HPV infection (35.8%) and vaccination (36.9%) was observed in 2016 from 13.3% and 8.6% in 2007, respectively. Willingness to be vaccinated against HPV decreased from 55.0% in 2007 to 25.8% in 2016, and the proportion of respondents expressing uncertainty increased from 28.3% in 2007 to 43.3% in 2016. Only 12.1% of men and 22.0% of women knew about the free national HPV vaccination program for girls, launched in June 2016. Younger women, with higher income level, awareness of the HPV vaccine, and perception of the seriousness of infections had a higher willingness to be vaccinated. A high education level, awareness of HPV infection and vaccination, and perception of the seriousness of infection were positively associated with the willingness of respondents to vaccinate their daughters. Raising the awareness of HPV infection and vaccination with appropriate knowledge is necessary for the successful implementation of the national HPV vaccination program.
