Abstract
OBJECTIVES
This study aimed to investigate changes in health behaviors, including cigarette smoking, alcohol drinking, physical activity, dietary behaviors, and obesity, before and during the coronavirus disease 2019 (COVID-19) pandemic using the Korea Youth Risk Behavior Survey (KYRBS) database.
METHODS
KYRBS data from 2015 to 2021 were used in this study. Differences in health behaviors between before (pre-pandemic period: 2018-2019) and during (pandemic period: 2020-2021) the pandemic were examined. Differences were compared using linear regression and the chi-square test considering the complex survey design after adjusting for grade level.
RESULTS
The prevalence of current cigarette smoking and current alcohol drinking significantly decreased in both male and female students during the pandemic compared to the pre-pandemic period. However, the prevalence of obesity significantly increased in both male and female students during the same period. When examining physical activity and dietary behaviors closely related to obesity, fast food consumption increased and fruit consumption decreased during the pandemic in both male and female students, whereas no significant changes in physical activity were observed in either male or female students.
CONCLUSIONS
The deterioration of adolescent dietary behaviors and an increase in the prevalence of obesity can increase the future disease burden, and concerted efforts at the individual and national levels are needed to reduce obesity and promote healthy dietary behaviors.

이 연구는 한국 청소년건강행태조사자료(KYRBS)를 사용하여 코로나19 유행 전후의 우리나라 청소년들의 흡연, 음주, 신체활동, 식습관, 비만 등의 건강행태의 변화에 대하여 살펴보고자 하였다. 이 연구에서는 2015년부터 2021년까지의 청소년건강행태조사자료를 사용하여, 코로나19 유행 이전 (2018-2019년)과 코로나 유행 이후 (2020-2021년) 기간의 건강행태의 변화에 대하여 조사하였다. 학년레벨을 보정한 후, 복합표본설계를 고려하여 로지스틱 회귀분석과 카이제곱검정을 이용하여 코로나19 유행 이전 (2018-2019년)과 비교하여, 코로나 유행 이후 (2020-2021년) 기간의 건강행태의 변화가 있었는지에 대하여 확인하였다. 그 결과, 코로나19 유행 이전 (2018-2019년)과 비교하여, 코로나19 유행 기간(2020-2021년) 동안에 현재흡연율과 현재음주율이 유의하게 감소하였다. 그러나 동일한 기간 동안에 남학생과 여학생 모두에서 비만율이 유의하게 증가하였는데, 비만율과 관련된 신체활동 및 식습관에 대하여 살펴보았을 때, 신체활동에서는 유의한 변화가 없었던 반면, 남학생과 여학생 모두에서 패스트푸드 섭취는 증가하고 과일섭취가 감소한 것으로 나타났다. 따라서 코로나19 유행기간 동안 흡연율 및 음주율 등의 청소년 건강에 유익한 변화도 있었으나, 비만율도 같이 증가한 것을 확인할 수 있었다. 청소년기의 식습관의 악화 및 비만율의 증가는 미래 우리나라의 질병부담을 증가시킬 수 있기 때문에, 청소년의 비만율을 낮추고 건강한 식습관을 증진시키기 위한 개인 및 사회 차원의 노력이 필요하다.
Key Message
-The current cigarette smoking and current alcohol drinking rates significantly decreased among Korean adolescents during the pandemic period compared to the pre-pandemic period.
-On the other hand, the obesity rate increased significantly especially among Korean male adolescents, which is accompanied by changes in dietary habits such as an increase in fast food intake and a decrease in fruit intake.

Abstract
OBJECTIVES
It is necessary to investigate tobacco or nicotine product (TNP) use which acts as a risk factor for coronavirus disease 2019 (COVID-19) infection. Especially, wearing a mask is difficult to practice while using TNP. Therefore, this study aimed to examine the association between TNP use behaviors and non-compliance with mask-wearing during the COVID-19 pandemic.
METHODS
The samples of 208,618 Korean adults from 2020 Community Health Survey in Korea were used. As an independent variable, TNP use behaviors such as TNP use status, changes in TNP use after the COVID-19 outbreak, TNP types, and attempt to quit were analyzed. Logistic regression was performed on gender-stratified participants.
RESULTS
Among men, the odds ratio (OR) of current and former TNP users were 2.00 (95% confidence interval [CI], 1.66 to 2.40) and 1.32 (95% CI, 1.09 to 1.60), respectively, compared to never users. In women, OR was 1.50 (95% CI, 1.00 to 2.26) for former users. Cigarette use was more associated with not wearing a mask than non-cigarette tobacco or nicotine product (NCTNP) use (OR, 1.53; 95% CI, 1.12 to 2.08). Men whose TNP use decreased had lower non-compliance (OR, 0.52; 95% CI, 0.36 to 0.74); while women whose TNP use increased had lower non-compliance (OR, 0.13; 95% CI, 0.07 to 0.26).
CONCLUSIONS
Current and former users were less likely to wear masks. Cigarette use was more associated with not wearing a mask than NCTNP use. Changes in TNP use showed association for men and women; however, in the opposite direction. Therefore, more attention should be paid to TNP use prevention and cessation support during the epidemic of respiratory infectious diseases. Moreover, it is necessary to identify risk factors of cigarette users in compliance with mask-wearing.

담배 또는 니코틴 제품 (Tobacco or Nicotine Products, TNPs) 현재사용자와 과거사용자는 비사용자 대비 마스크 미착용 연관성이 높고, 비궐련 담배 또는 니코틴 제품 (Non-Cigarette Tobacco or Nicotine Products, NCTNPs) 사용자보다는 일반담배 사용자의 마스크 미착용 연관성이 높다. 남성에서는 코로나19 유행 이전 대비 TNPs 사용이 감소했을 때, 여성에서는 증가했을 때 마스크 미착용 연관성이 낮았다. 따라서 호흡기 감염병 유행 시기에는 더욱 TNPs 사용 예방과 금연 지원에 관심을 가질 것을 제안한다.
Key Message
During the epidemic of respiratory infectious diseases, more attention should be paid to tobacco or nicotine products (TNPs) use prevention and cessation support.

Abstract
OBJECTIVES
This study examined socioeconomic inequalities in compliance with precautions and health behavior changes during the coronavirus disease 2019 (COVID-19) outbreak using a representative Korean sample.
METHODS
This exploratory study utilized around 210,000 participants aged ≥25 years in the Korean Community Health Survey 2020. Socioeconomic status was measured with educational attainment and household income. Outcomes included non-compliance with 8 precaution measures and deterioration in 6 health behaviors. The relative inequality index (RII) was calculated to quantify the degree of inequality by education and income level. RII values >1.0 indicate that deprived people have a higher frequency of health problems, and RII values <1.0 conversely indicate a higher frequency of health problems in more advantaged groups.
RESULTS
People with lower education or income levels tended to have higher rates of non-compliance with COVID-19 safety precautions (RII range, 1.20 to 3.05). Lower education and income levels were associated with an increased smoking amount (RII=2.10 and 1.67, respectively) and sleep duration changes (RII=1.21 and 1.36, respectively). On the contrary, higher education and income levels were associated with decreased physical activity (RII=0.59 and 0.77, respectively) and increased delivery food consumption (RII=0.27 and 0.37, respectively). However, increased alcohol drinking was associated with lower education and income levels in younger men (RII=1.73 and 1.31, respectively), but with higher levels in younger women (RII=0.73 and 0.68, respectively).
CONCLUSIONS
Our findings suggest the need to develop customized strategies, considering the characteristics of the target population, to decrease the burden and impact of the COVID-19 outbreak.

코로나19 유행기간 동안 예방지침 준수율과 건강관련 생활습관이 나빠지는 정도는 사회경제적 수준에 따라 차이가 있다. 전반적으로 코로나19 예방지침 준수율은 높았지만, 사회경제수준이 낮을수록 예방지침 준수율도 낮아지는 경향을 보였다. 하지만, 사회경제수준과 생활습관 악화의 관계는 성, 연령, 생활습관의 종류에 따라 달랐다.
Key Message
This study of a representative Korean sample found that socioeconomic inequalities existed in compliance with COVID-19 precautions and in health behavior deterioration.
There is a need to develop target group-specific strategies to reduce health inequalities and the long-term health burden of the COVID-19 outbreak.

Abstract
OBJECTIVES
This study aimed to examine the trends in health behaviors in Korean population using data from the Korea National Health and Nutrition Examination Survey (KNHANES).
METHODS
The subjects were 96,408 adults aged 19 years or older who participated in the first (1998) through seventh (2016-2018) KNHANES health interview. The prevalence of health behaviors (cigarette smoking, alcohol drinking, and physical activity) and annual percent change (APC) were estimated using SAS and the Joinpoint program.
RESULTS
The prevalence of current cigarette smoking in men decreased by 2.8%p (APC= -2.8, p< 0.001) annually over the 20-year period, and the prevalence of exposure to secondhand smoke at home substantially decreased compared to 2005 (APC= -8.8, p< 0.001). Compared to 2005, the prevalence of current alcohol drinking in women, but not men, increased (APC= 2.0, p< 0.001), and the prevalence of binge drinking decreased in men (APC= -0.7, p< 0.001) and increased in women (APC= 2.4, p< 0.001). The prevalence of aerobic physical activity decreased from 2014 in both gendersd (p< 0.001). The prevalence of healthy behaviors practice (non-smoking, alcohol abstinence, and aerobic physical activity) was down-trending (APC= -5.3, p< 0.001), especially among women (APC= -6.4, p< 0.001).
CONCLUSIONS
Over the past 20 years, smoking behaviors improved. However, drinking behavior was unchanged and physical activity indicators markedly decreased. More active programs are necessary for improving health behaviors, which are major risk factors linked to chronic diseases.

Abstract
The Korea National Health and Nutrition Examination Survey (KNHANES) was initiated in 1998 to provide evidence for the development and evaluation of health policies and programs. The Korea Disease Control and Prevention Agency is responsible for the KNHANES and has conducted it as a series of surveys. Over the past 20 years, efforts to produce accurate, timely, and nationwide health statistics have been refined by establishing a continuous annual survey system with full-time field staff, incrementally expanding survey components, collaborating with relevant academic societies for quality control, and revising the survey methods. Additionally, the utility of the collected data was increased by linking the KNHANES data with related data from other government agencies or institutions and making the overall data publicly available on the official website of KNHANES (https://knhanes.kdca.go.kr). Additional long-term plans are being developed, including plans to continue producing nationwide health indicators and invigorating the utilization of the KNHANES data.

Abstract
OBJECTIVES
The purpose of this study was to estimate the effects of health-risk behaviors, alone and in combination, on health outcomes.
METHODS
This study used sample cohort data provided by the National Health Insurance Service focusing on the use of hospital services, direct medical expenses, length of stay, and re-entry rate according to health-risk behaviors. A frequency analysis and the chi-square test were used to investigate associations between the demographic characteristics of study subjects and their health-risk behaviors. The strength of the association of each factor was calculated as the odds ratio in a crossover analysis.
RESULTS
Obesity had the largest effect, especially in combination with smoking and drinking. In particular, significant associations were shown with the duration of hospitalization and direct medical expenses. After adjustment for sex, age, economic status, and pre-existing medical conditions, the duration of hospitalization was 7.37 times longer and that of medical expenses was 5.18 times higher in the obese group relative to the non-obese group. Drinking showed a statistically significant association with the number of days of hospitalization. After adjusting for the control variables, the number of hospital days was 1.24 longer in the drinking group than in the non-drinking group.
CONCLUSIONS
An analysis of combinations of health risk factors showed obesity had the largest effect.

Abstract
OBJECTIVES
Previous studies have shown that marital status is associated with household composition and living arrangements, which partially explain observed differences in health status according to marital status. However, due to the rapid socioeconomic and demographic transformations of the last few decades, the distribution of marital status among middle-aged adults has become more diverse. Therefore, this study aimed to obtain up-to-date information on the associations between marital status and health and to investigate the implications of these findings for conventional explanations of the health effects of marriage.
METHODS
The data for this study were obtained from the 2015 Korean Community Health Study. We compared 4 modifiable lifestyle behaviors—smoking, alcohol consumption, physical activity, and self-rated health status—as outcome variables in association with marital status in Korean middle-aged men (age 40-44) living in Seoul and other regions.
RESULTS
Married men showed the lowest cigarette smoking prevalence and the highest subjective health status both before and after adjusting for education and income. The odds of engaging in vigorous physical activity did not show a major difference before and after adjustment for income and education.
CONCLUSIONS
In married men, the prevalence of cigarette smoking was lowest and subjective health status was highest, similar to previous studies. However, the prevalence of engaging in physical activity was highest in divorced/widowed/separated men. The health behaviors and health status of Korean middle-aged adults should be more closely followed, since they are representative of demographic changes in the Korean population.

Abstract
OBJECTIVES
This study examined differences in health behaviors between elderly people living alone and with others; it also investigated whether the effect of living with others differs according to housemate type, namely a spouse and/or younger generations.
METHODS
Gender-stratified data from the 2013 Korea Community Health Survey for individuals aged 60 to 74 living in Seoul were analyzed. Logistic regression modeling was conducted to obtain odds ratios (ORs) and 95% confidence intervals (CIs) of the outcome variables (smoking, drinking, eating salty foods, inactive lifestyle) for the variables of interest (living alone/with others, housemate type). Models were adjusted for confounding variables including history of medical conditions, employment type, and adjusted household income.
RESULTS
Analysis involved 1,814 men and 2,199 women. Risk of smoking was 1.80 times (95% CI, 1.21 to 2.67) higher for men living alone than living with others. Risk of eating salty foods was 0.78 times lower (95% CI, 0.62 to 0.98) for men living with a spouse than a spouse and younger generations. Risk of inactive lifestyle was 1.47 times higher (95% CI, 1.13 to 1.92) for women living alone. Risk of smoking was higher for women living alone (OR, 1.41; 95% CI, 1.03 to 1.92) or with younger generations (OR, 9.12; 95% CI, 2.04 to 40.80) than with a spouse and younger generations.
CONCLUSIONS
Living alone was associated with smoking in men and physical activity in women; housemate type was associated with dietary habits in men and smoking in women. These gender-specific findings can help identify groups of individuals vulnerable to risky health behaviors and to develop policies.

Abstract
OBJECTIVES
We examined the associations between happiness and a wide range of health behaviors in South Korean adolescents.
METHODS
Study data were derived from the ninth Korea Youth Risk Behavior Web-based Survey administered from June to July 2013. In addition to happiness levels, the questionnaire included items on sociodemographics and health-related lifestyle factors (smoking, drinking, eating breakfast, fruit and vegetable consumption, physical activity, sedentary behavior, and hours of sleep).
RESULTS
The multivariate analysis revealed that higher levels of happiness were associated with not smoking or drinking, eating breakfast, eating fruits daily, vegetable consumption, participating in at least 60 minutes of physical activity a day, avoiding sedentary behavior, and hours of sleep. Additionally, sex differences were found in relationships between happiness and eating fruit daily, participation in physical activity, and sedentary behavior.
CONCLUSIONS
These results encourage public health professionals to consider the psychological aspects of adolescent life in working to improve their health behaviors and outcomes.

Abstract
OBJECTIVES
Responses to health-related items on the Community Health Survey (CHS) provide evidence that is used to develop community-based health policy. This study aimed to assess the test-retest reliability of selected health behavioral items on the CHS according to item category, response period, and response scale.
METHODS
A sample of 159 men and women 20 to 69 years of age participated in a test-retest with an interval of 14 to 21 days. A total of 28 items relating to smoking, alcohol consumption, diet and weight control, and mental health were selected. We evaluated the test-retest reliability of the items using kappa statistics.
RESULTS
Kappa values ranged from 0.44 to 0.93. Items concerning habits had higher kappa values (mean, 0.7; standard error, 0.05) than items concerning awareness or attitudes (p=0.012). The kappa value of items with two- to four-point scales was 0.63, which was higher than the value of 0.59 for items with scales involving five or more points, although this difference was not statistically significant. Different kappa values were observed for each reference period, but no statistically significant differences were noted.
CONCLUSIONS
The test-retest reliability of the CHS items that we studied was associated with item category. Further study of the relationship between item category and reliability in domains other than health behaviors is required.

Abstract
In order to respond to the increasing burden of non-communicable diseases (NCDs) worldwide, the World Health Organization developed the global action plan (GAP), which included nine targets and 25 indicators to monitor the targets. Owing to space constraints, the article reviewed the status of 17 indicators for seven targets out of nine targets in the GAP in Korea. Most of these 17 indicators required additional analysis with existing national data to evaluate the status in Korea. Based on the result from evaluating indicators, the current NCD policy strategy and resources in Korea seemed unlikely to reach the GAP goals, unless innovative policy changes was planned to reduce NCD risk factors particularly focusing on smoking, excessive drinking, and insufficient physical activity.

Abstract
OBJECTIVESThe aim of this study was to investigate the effect of changes in cardiovascular disease (CVD) risk factors on progression from prehypertension (PreHTN) to hypertension (HTN) using an 8-yr prospective Korean Cancer Prevention Study (KCPS) by the National Health Insurance Corporation (NHIC) in Korea.
METHODSA total of 16,229 subjects, aged 30 to 54, with new onset preHTN at baseline (1994-1996) in a biennial national medical exam were selected and followed up till 2004 at 2-yr intervals. All subjects underwent a biennial health examination including biochemical measurements and behavior. The log-rank test was performed to assess the relationship between changes in CVD risk factors and progression to HTN. The Cox proportional hazard model was used to identify factors influencing progression to HTN.
RESULTSWith regards the progression rate in men, ex-smokers (42.9%), abstainers (37.5%), and regular exercisers (37.6%) showed a slower progression rate than continuous smokers (49.5%) and continuous drinkers (50.9%). In women, those who participated in regular exercise (22.6%) had a lower rate of progression than continuous non-exercisers (36.1%). According to the results of the Cox proportional hazard model, improvements in smoking (hazard ratio [HR], 0.756), drinking (HR, 0.669), regular exercise (HR, 0.653), body mass index (HR, 0.715), and total cholesterol (HR, 0.788) played a protective role in progression to HTN in men, while in women, participating in regular exercise (HR, 0.534) was beneficial.
CONCLUSIONImprovements in CVD-related behaviors diminished the progression rate of HTN. This study suggests that individuals with PreHTN should be targeted for specific health behavioral intervention to prevent the progression of HTN.

Abstract
Variables derived from the health belief model were studied in relation to practices of health behavior, which was measured in terms of thoroughness. Data were collected from the sample of 984 adults living in A-Gu of Pusan, during in-home interviews using structured questionnaires.
Women practiced more health behaviors than men. The significant negative relationship was found between perceived barriers to health behavior and practices of health behavior in men and women. In addition, emotional support in men and perceived benefits of health behavior in women were also significant predictors of health behaviors.
These findings suggest that in the study population, perceived barriers is the most powerful predictor for practices of health behavior and social support is also important for facilitating positive health behaviors.

Abstract
To investigate the association of individual health behaviors with imune response against tumor or viral infection, peripheral blood lymphocytes of 185 healthy males in aged from 35 to 44 years for natural killer(NK) cell activity, frequencies of lymphocytes subsets and proliferation response of T and B cell. NK cell activity was determined by Cr release activity assay and lymphocytes subsets were counted using surface antigens(CD4, CD8, CD56) by flow cytometry. The responsiveness of T and B were measured as proliferation stimulated by mitogens. Subjects were classified into four distinct lifestyle patterns, health promotive lifestyle, passive lifestyle, fitness lifestyle and hedonic lifestyle from information on their health behaviors(cigarette smoking, alcohol consumption, and physical activity). Health promotive lifestyle had the highest NK cell activity(Lu30/10(6)CD56) which was significantly higher than hedonic lifestyle)p<0.05). The responsiveness of T cell was significantly lower in passive lifestyle and hedonic lifestyles compared to health promotive lifestyle and fitness lifestyles(p<0.05). However, there was no significant difference in the responsiveness of B cell, CD4, and CD8 among four lifestyles. This cross-sectional study showed the NK cell activity in individuals with desirable health behaviors was lower. The variation of immunity among individuals was not considered in this study, hence the intervention study reflection individual variations is recommended.

Abstract
Epidemiologic research has demonstrated that varying grade of physical activity has protective effects on several chronic diseases, including coronary heart disease, hypertension, diabetes mellitus, osteporosis, anxiety and depression. Despite the importance of physical activity as an health promotion factor, there have been only a few research data available in Korea. This telephone interview survey on randomly sampled 1,060 adultsaged 15-69 years was carried out to find out the prevalence of self-reported leisure-time physical activity among Korean adults in terms of health promotion practice. The nationwide telephone interview survey was conducted from April through May 1997.
Multistage stratified random sampling method was used for sample selection, the respondent was randomly selected from an entire group of adults who lived at the residence connected with the telephone number. A total of 1,060 adults were interviewed and the interviewees' leisure-time physical activity was categorized into four patterns: 'physically inactive', 'irregularly active', 'regularly active, not intensive', and 'regularly active, intensive'. About 53% of the respondents were physically inactive, 15% irregularly active, 14% regularly active, and only 18% were regularly active, intensive. Women were less active than men anc persons of lower socioeconomic status(SES) were less active than higher SES. Physical activity was not significantly associated with smoking status, drinking pattern and overweight, but negatively associated with daily smoking amount and total duration of smoking in smokers. Individuals with higher lever of physical activity were more likely to check blood pressure regularly and have had screening examination for stomach cancer. Conclusively, the proportion of Korean people who perform appropriate level of physical activity in terms of health promotion is still very low, thus an enforced intervention program becomes indispensable to achieve the national health goal by the year 2000.
