Purpose: Influenza vaccination coverage in adolescents is an important goal of informed vaccination policies and programs. This study aimed to estimate the influenza vaccination coverage rate and investigate the factors influencing influenza vaccination coverage in Korean adolescents. Methods: The study population consisted of 5,213 adolescents (aged 12 to 18 years) who participated in the Korea National Health and Nutrition Examination Survey from 2007 to 2014 (except for 2013). We analyzed influenza vaccination coverage in relation to the demographics, lifestyle, and medical characteristics of the participants. Results: The influenza vaccination coverage rate, during the study period, was 23.2% (range, 21.1% to 24.7%). Logistic regression analysis revealed that factors influencing influenza vaccination were elementary school age (odds ratio [OR], 1.706; 95% confidence interval [CI], 1.526 to 1.906), good self-rated health status (OR, 1.192; 95% CI, 1.057 to 1.344), a drinking status of non-drinker (OR, 1.769; 95% CI, 1.474 to 2.122), a smoking status of non-smoker (OR, 1.459; 95% CI, 1.144 to 1.860), and a past diagnosis of pneumonia (OR, 1.469; 95% CI, 1.076 to 2.006). Conclusions: Influenza vaccination coverage in Korean adolescents is relatively low. Special efforts are needed to increase vaccination coverage for adolescent groups with low vaccination rates including adolescent smokers and drinkers, middle and high school age adolescents, and adolescents with a poor self-rated health status.

This study was conducted to investigate the kinds of health promotion program which workers want, worker's intention for participation, proper method, time, duration and manager. A self-administered questionnaire method was used to collect data from 412 employees of 3 worksites in Chungpook and Kyungkee. This survey was carried out from Aug. 10 to Aug. 20, 1998. The results of this study are as follows: 1. In male, among health promotion programs, favorite ones were physical fitness(32.2%), periodic health check-up(24.6%), and stress management(18.0%). In female, among health promotion programs, favorite ones were periodic health check-up(26.0%), physical fitness(22.0%), and body weight control(19.5%). 2. The more young subjects are, the more they like physical fitness program, and the female like body weight control program regardless of BMI. Manufacturing worker preferred back pain prevention program to clerical worker did. In female, drinker preferred stress management program to non-drinker did. 3. The more old subjects are, the more they like back pain prevention program, and non-smoker preferred body weight control program to smoker did. 4. In health promotion program format which the subjects wanted, learning of self-examination techniques was 41.1%, worksite screening was 3l.0%, availability of pamphlets and audiovisual materials was 20.0%, presentation of worksite educational sessions was 7.9%, and the most wanted manager for the program was medical doctor and then nurse, physical trainer, psychological counselor. The favorite health promotion program duration was less than 30 minutes(49.6%), and the favorite time was before work(49.6%). 5. Among respondents, 48.5% was smokers, 81.8% was drinkers, 39.9% engaged in the regular exercise, 68.2% engaged in regular diet habit. In vaccination, 50.2%, if possible, wanted to be vaccinated and 37.6% never wanted to be vaccinated. 6. Ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit responded they were in good health. There was a significant difference between exercise and health status. Need and intention for participation of health promotion program were high in ex-smoker, ex-drinker, the subjects in the regular exercise, and in the regular diet habit. According to results for this study, if the favorite programs, exercise, periodic health check-up, stress management program, are operated at a proper time and with managers they want, this programs can really raise the participation of employees. And as employees want to learn self-examination techniques if worksite educational sessions are performed, health promotion program can effectively be operated.

The age of the very first smoking is a significant indicator of life-long health status. Smoking prevention intervention was actively conducted based in middle and high schools with the support of the Korean Act for Health Promotion since 1998. These governmental supports became large and various smoking prevention programs were developed and conducted in diverse standards and perspectives. This study made a comprehensive descriptive literature review on smoking prevention educational programs for youth in Korea to identify the intervention quality and effectiveness of them for future smoking prevention program development. A total of 28 peer-reviewed journal articles published between May, 1995 and May 2005 (for the last 10 years) were finally included in this review process. The study participants should be adolescences in middle or high schools in Korea and the intervention types of the review studies should be smoking prevention or cessation educational programs. The outcomes of the reviewed studies were reanalyzed by the participants' characteristics, theory basement, evaluation design, intervention period, evaluation outcomes, and program effectiveness Most smoking intervention programs were not specified by sex and smoking status. Largely most intervention programs focused on male students although female students' smoking percent is increasing including both smokers and nonsmokers. Based on the school grades, the large percents of smoking intervention were conducted to the first grade of middle school and the first grade of high school. Almost 70% of the reviewed studies did not apply any health behavior change theories and the Transtheoretical model and social cognitive theory were utilized in 7 studies among the last reviewed 30%. The theory-based intervention studies had greater effectiveness than the non-theory based studies. More than 90% had quasi-experimental evaluation design and the effectiveness of the non-experimental designed study seemed over estimated than the quasi-experimental or experimental designed studies. More than 60% of the reviewed studies made their education for less than j days, over a short period and the evaluation factors were knowledge and attitude in general which can be obtained in short intervention period. Therefore, smoking intervention programs for youth in Korea need to be modified in terms of research design such as the intervention period, intervention-evaluation design, theory-based approach, and population-focused intervention specification.

This study was carried out to discover the effects of eating habits and health-related life style on blood pressure, $\gamma$-Glutamic acid Peptide Transferase($\gamma$-GPT), blood glucose and High Density Lipoprotein-Cholesterol(HDL-C). 185 subjects(85 male, 100 female) were selected, who were living in the Cheonju area aged 40#s to 60#s. The mean systollic blood pressure(SBP), diastollic blood pressure (DBP), $\gamma$-GPT, fasting blood sugar(FBS) and HDL-C for all the subjects were 118mmHg, 77mmHg, 281U/l, 90mg/dl and 45mg/dl, respectively. The SBP and DBP for subuects over 60 years old were 126mmHg and 81mmHg and were significantly higher than subjects in their 40#s and 50#s(p<0.001, p<0.005). The HDL-C of the group that rarely ate breakfast was 57mg/dl and that was significantly higher than the 44mg/dl scored by those who ate breakfast everyday(p<0.05). The SBP for subjects having a snack 2-3 times/week was 125mmHg and that was significantly higher than the 114mmHg of those having a snack everyday(p<0.05). The $\gamma$-GPT for subjects consuming alcohol everyday was 44IU/L and that was significantly higher than 18IU/I of the non-drinking group(p<0.001). The $\gamma$-GPT of light smokers was 53IU/I and that was significantly higher than the 22IU/I for non-smoking participants(p<0.001). The DBP, SBP, $\gamma$-GPT, FBS and HDL-C related to exercise not significantly different. The SBP(p<0.001) and DBP(p-0.01) between age group was positively correlated. The $\gamma$-GPT between drinking frequency(p<0.001), drinking quantity(p<0.05), and smoking(p<0.05) was also positively correlated. The FBS between exercises had a negative correlation(p<0.05), and the HDL-C between breakfast had a negative correlation(p<0.05). These results indicate that decreasing drinking and smoking, when combined with appropriate exercise, will decrease the $\gamma$-GPT and fasting blood sugar level, and help preventing adult diseases.

Objectives: The purpose of this study is to identify the policy compliance according to the socio-demographic characteristics, stress, satisfaction of relationship, Health Belief Model and characteristics of smoking behaviors and knowledge related smoking of the residents living in the Smoke-free apartment and to investigate the change of the smoking related behavior before and after the implementation of the policy. Methods: The subjects of the survey were 293 residents aged 19 or older who reside in apartments six months after the designation of Smoke-free apartment located in Daejeon. All collected data were analyzed using T-test, ANOVA and Hierarchical multiple regression of SPSS for windows(ver 24.0) program. Results: The policy compliance was higher in women and those who lived for less than two years, and non-smokers were significantly higher. The policy compliance of the whole subjects was related to satisfaction with the surrounding relationship, perceived disability about smoking cessation, frequency of smoking and the amount of smoking. The policy compliance of the whole subjects was related to the satisfaction of the surrounding relationship, the perceived disability about smoking cessation, and the amount of smoking. In addition, after the implementation of the gold research station designation policy, it had a positive impact on smoker's smoking behavior and resulted in reducing the frequency of secondhand smoke among residents. Conclusions: In order to increase the compliance of the non-smoking policy It is necessary to continuously expand the indoor smoking cessation zone policy, develop policies and supplement the health belief model components.

The levels of harmful components in aerosols from heated tobacco products (HTPs) have been reported to be significantly lower than in cigarette smoke. However, it remains unclear whether the use of HTPs can mitigate the cardiovascular risks associated with cigarette smoking (CS). The objective of this study was to investigate the effects of a short-term switch from CS to HTP use on cardiac autonomic regulation (CAR). Seven healthy male smokers completed an open-label, randomized, cross-over trial consisting of five days of CS, use of three different HTPs (IQOS use, IQ; lil SOLID use, LS; lil HYBRID use, LH), or non-smoking (NS). Each session was separated by a one-week washout period, and levels of exhaled carbon monoxide (CO) and carboxyhemoglobin (COHb), systolic (SBP) and diastolic blood pressure (DBP), and heart rate variability (HRV) reflecting CAR were assessed before use of the product assigned to each session and at 24, 48, 72, 96, and 120 hr after use. Levels of exhaled CO and COHb were statistically significantly reduced only during NS. There were no statistical changes in SBP and DBP within any session. However, in HRV spectral analysis, log-transformed high frequency (lnHF) increased statistically significantly in IQ, LS, and NS, respectively. Normalized HF (HFnu) was significantly increased in NS and LH, respectively. lnHF and HFnu showed significant interaction effects. The findings of this study suggest that a short-term switch to HTPs instead of CS may lead to different distribution patterns of CAR, primarily driven by enhanced cardiac vagal tone.

Harmful and potentially harmful constituents (HPHCs) are chemical compounds in tobacco smoke that cause harm to smokers and non-smokers. This study established and validated methods for the analysis of HPHCs from mainstream cigarette smoke. The analyzed HPHCs were categorized into seven groups: aromatic amines, volatile organic compounds (VOCs), heavy metals, tobacco specific nitrosamines (TSNAs), benzo[a]pyrene (B[a]P), ammonia, and carbonyl compounds. The methods were validated by specificity, linearity, limit of detection (LOD), accuracy, precision, and recovery. These validated methods were then applied to the reference cigarettes (1R5F, 3R4F). The correlation coefficients (r²) for the calibration curves of the seven groups were over 0.995. The LODs showed values of 0.01-0.04 ng/cig cig for aromatic amines, 0.01-0.16 μg/cig for VOCs, 0.01-1.27 ng/cig for heavy metals, 0.06-0.28 ng/cig for TSNAs, 0.04 ng/cig for benzo[a]pyrene, 0.08 μg/cig for ammonia, and 0.78-1.77 μg/cig for carbonyl compounds. The precisions obtained from the intra and inter-day batches were less than 15%. The accuracy and the recovery range were less than 15% and 79.2-117.5%, respectively. The proposed methods can therefore be applied for determining HPHCs in tobacco mainstream smoke.

The objectives of this study are to identify health behaviors and health problems. and the relations between health behaviors and health problems of female workers in the retail business. The number of subjects were 200 female workers of 6 department stores in Seoul and Kyonggi area, whose jobs last more than 6 months as retail employees. The data was collected during 2 months from July 1 to August 30, 1998. The Cornell Medical Index Health Questionnaire(CMI) was used to measure their health problems, while health behaViorn were investigated in terms of 'smoking', 'alcohol', exercise', 'diet', and 'sleeping'. The data were analyzed with frequency. percentage, t-test, ANOVA test, and $X^2-test$ by SPSS PC+ program. The results of this study are as follows: 1. Out of health problems. Digestive symptoms occupied the highest percent number. nervous ones the second and cardiovascular ones the third among physical health problems of retail female workers. The most frequent mental health problem was 'adequacy' and the next, 'tension' and 'anger', 2, Health problems according to general characteristics of subjects were shown that the younger or the unmarried complained more than the older or the married, especially in the items of 'eye and ear', 'respiratory system', 'cardiovascular system', 'digestive tract', 'nervous system', 'adequacy', and 'depression'. The longer working duration they have had, the more they complained of 'respiratory system' and 'adequacy'. The lower academic careers complained of 'nervous' than the higher ones with statistical significance. 3. The analysis of daily health clinic notes showed that respiratory complaints were the highest percent, successively followed by digestive tract, nervous one, external injury, musculoskeletal system, urinary-reproductive system and others. 4. The level of their health practice was generally low in smoking, diet habit and alcohol intake, exercise, sleeping, very low especially in smoking, diet, alcohol intake, and exercise among them all. 5. Present smokers and ones with past experience complained of physical and mental health problems of 'respiratory system', 'digestive tract', 'skin', 'nervous', 'urinary-reproductive system', 'fatigability', adequacy', 'depression', 'anxiety', 'anger' and 'tension', than non smokers, with statistical difference. Workers without having breakfast and with irregular diet had more complaints on 'digestive tract', 'adequacy' and 'tension', than those who had regular dietary habit. The less the subjects slept, the more they complained of eye and ear, cardiovascular system. The subjects who drank alcohol complained more digestive problem. However, whether they exercise or not did not affect physical and mental health problems in a significant manner. 6. The subjects' age and marital status were statistically significant relating to health behaviors, as the younger or unmarried recorded a low level of health practice in smoking, drinking, dietary habit. Based on the results, the suggestions are made as follows: 1. Health education program on smoking, alcohol intake, diet habit is needed to improve health problems and health behavior of female retail workers. 2. The unmarried workers of late teen and twenties, who are transitional period from teenagers to adulthood are important targets for health promotion program especially for maternal health. 3. Better working environment with sufficient time and facilities for workers to relax is required to promote female sales workers' health. 4. Further research is required to identify the relation between workers' visual fatigue and intense lights for the display of goods.

A retrospective review of the histopathology and clinical information of primary lung cancer was performed to investigate the trends in the histologic type related to sex, age, and smoking history. During January 1988 and July 1995, 541 pateints were diagnosed as primary lung cancer at the Korea Univeristy Anam Hospital. Male (423) to female(118) ratio was 3. 6:1. The most frequent histologic type of lung cancer in male patients was squamous cell carcinoma (223 patients, 52.7%) followed by adenocarcinoma (86, 20.3%) and small cell carcinoma (85, 20.1 %). In female patients, adenocarcinoma (64, 54.2%) wa most common, which was followed by squamous cell carcinoma (22, 18.6%) and small cell carcinoma (22, 18. 6%). The incidence of adenocarnimoma had an increased tendency recently (14.3% in 1988, 33.3% in 1995)(P=0.019). The predominant type in smokers was squamous cell carcinoma; whereas adenocarcinoma was the most frequent type in non-smokers. The proportion of patients aged less than 40 years (younger group) was 4. 0% (n=22). Of them, adenocarcinoma (7) and small cell carcinoma (7) were most common. In patients older than 40 years (older group, n=519), 243 (46.8%) patients had squamous cell carcinoma, and 143 (27.6%) adenocarcinoma. As age increased, the prevalence of squamous cell carcinoma was increased (P=0.0005), adenocarcinoma decreased (P=NS), and small cell carcinoma remained unchanged. We suggest above data as a clinical guidance for management of primary lung cancer.

Transtheoretical model of change has been proven very effective in explaining both the acquisition and cessation of many health related behaviors. The objectives of this study were to describe the distribution of smokers by stage of change of smoking, alcoholic drinking, and exercising in rural residents and to develope health promotion strategies. This study was done in Okchun County of Chungbuk Province. The representative sample were 892 residents over 30 years old. The questionnaires of interview included socio-demographic, the six stage distribution of smoking, alcoholic drinking, and exercising. In male, 50.6% of smokers were in the precontemplation stage, 32.5% in the contemplation. In female, corresponding figures were 60.6% and 28.8%. Precontemplation and contemplation stage of drinker were 72.8%, 19.3% in male and 80.3%, 15.5%. Distribution of exercise were 80.6%, 1.8% in male, 87.6%, 1.2% in female, respectively. The stage distribution of smoker, alcoholic drinker, and exerciser was shift to left of the distribution. And the stage distribution was slightly differ with each health behavior. The stage of change with smoking, drinking and exercising was correlated with each other but not concordant. So interventions in rural residents need to take into account the large proportion of precontemplators repeatedly observed among smoker, drinker, and non-exerciser. And intervention strategies of each risk behavior should be different approach. Result of concordance analysis suggest reconstruct validity of the transtheoretical model in our country due to ethnic and sociocultural difference. This results and theory should be tested in prospective intervention studies for seeking the possible gateway of health behavior.
