Associations of physical activity at work and household income with obesity: a cross-sectional study among rural adults in Korea / 한국역학회지

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.

Public Attitudes towards Cancer Survivors among Korean Adults / Journal of the Korean Cancer Association, 대한암학회지

Purpose@#We evaluated public attitudes towards cancer survivors and identified the characteristics associated with these attitudes in Korea. @*Materials and Methods@#We performed this cross-sectional study using proportionate quota random sampling of the 2015 Korean Census. In May 2017, investigators conducted face-to-face interviews with 1,500 Korean volunteers aged between 20 and 79 years. The questionnaire recorded sociodemographic factors, smoking and drinking habits, cancer history in family and acquaintances, interest in cancer survivors, cancer-survivor blame, and attitudes towards cancer survivors. @*Results@#Many participants had negative attitudes towards cancer survivors. People with a monthly household income above US $7,000 were less likely to have a negative attitude than those with monthly incomes below US $1,499. People in their 70s, without a religion, living in rural areas, smokers, or those who blame cancer survivors for their own cancer were more likely to have a negative attitude than people outside these categories. People interested in cancer survivors were less likely to have a negative attitude than those who were not interested. @*Conclusion@#To improve attitudes towards cancer survivors, it will be necessary to increase interest in cancer survivors through education, publicity, and advocacy using strategic messaging that focuses on social and institutional aspects and emphasizes that responsibility for cancer should not be attributed to cancer patients. Inducing the public to be interested in cancer survivors will be important for positive attitudes toward cancer survivors.

Effects of a cancer prevention education program on elementary school students' knowledge, attitude, self-efficacy, and intentions in South Korea / 한국역학회지

OBJECTIVES@#Most children and adolescents have low levels of cancer knowledge and awareness, and infrequently engage in preventive behaviors. This study examined the effects of a short classroom-based intervention for cancer prevention on knowledge, attitude toward cancer preventability, self-efficacy, and behavioral intentions of fifth-grade elementary school students.@*METHODS@#The study was based on a pre-post-follow-up, 2-group, quasi-experimental design. Participants in the intervention group attended two 40-minute sessions on cancer prevention education and watched a music video about cancer prevention, while participants in the control group were only exposed to the music video. Self-reported knowledge, attitude toward cancer preventability, self-efficacy, and behavioral intentions were assessed 1 week pre-intervention and post-intervention, as well as 3 months post-intervention.@*RESULTS@#The 3-month post-intervention results revealed partial effects, indicating that the education intervention improved knowledge and attitudes toward cancer preventability; however, no effects were observed on self-efficacy and behavioral intentions 3 months after the intervention.@*CONCLUSIONS@#Long-term regular booster sessions are required to improve not only social-cognitive factors, but also behavioral intentions, which could result in behavior changes promoting cancer prevention.

Factors affecting satisfaction with cancer information provided through the social networking services of the National Cancer Information Center in Korea / 한국역학회지

OBJECTIVES: This study aimed to identify the characteristics of social networking service (SNS) users and to assess the relationship of those factors to user satisfaction with the SNSs of the National Cancer Information Center (NCIC) in South Korea. METHODS: A Web-based survey was completed by 1,670 users of the NCIC SNSs, who provided data on the sources they consulted for information about cancer, determinants of SNS use, sources of NCIC SNS awareness, the time of day they used the SNS, and their satisfaction level. RESULTS: Facebook users mainly became aware of the NCIC SNSs through an acquaintance's recommendation, while Twitter was accessed through other SNSs or blogs. Users in their 30s were less satisfied with the NCIC SNSs than those in their teens and 20s. Browsing for cancer-related information on the Internet, prioritizing information quality, and engaging in active use were related to a high level of satisfaction with the NCIC SNSs. Individuals who were exposed to the NCIC SNSs through other SNSs or printed materials were less satisfied with their experience of the NCIC SNSs than those who received a recommendation from an acquaintance. CONCLUSIONS: These findings may act as a catalyst to guide public health agencies to enhance their use of SNSs.

Happiness and health behaviors in South Korean adolescents: a cross-sectional study / 한국역학회지

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.

News Portrayal of Cancer: Content Analysis of Threat and Efficacy by Cancer Type and Comparison with Incidence and Mortality in Korea

How the news media cover cancer may have profound significance for cancer prevention and control; however, little is known about the actual content of cancer news coverage in Korea. This research thus aimed to examine news portrayal of specific cancer types with respect to threat and efficacy, and to investigate whether news portrayal corresponds to actual cancer statistics. A content analysis of 1,138 cancer news stories was conducted, using a representative sample from 23 news outlets (television, newspapers, and other news media) in Korea over a 5-year period from 2008 to 2012. Cancer incidence and mortality rates were obtained from the Korean Statistical Information Service. Results suggest that threat was most prominent in news stories on pancreatic cancer (with 87% of the articles containing threat information with specific details), followed by liver (80%) and lung cancers (70%), and least in stomach cancer (41%). Efficacy information with details was conveyed most often in articles on colorectal (54%), skin (54%), and liver (50%) cancers, and least in thyroid cancer (17%). In terms of discrepancies between news portrayal and actual statistics, the threat of pancreatic and liver cancers was overreported, whereas the threat of stomach and prostate cancers was underreported. Efficacy information regarding cervical and colorectal cancers was overrepresented in the news relative to cancer statistics; efficacy of lung and thyroid cancers was underreported. Findings provide important implications for medical professionals to understand news information about particular cancers as a basis for public (mis)perception, and to communicate effectively about cancer risk with the public and patients.

What predicts the trust of online health information? / 한국역학회지

OBJECTIVES: Little attention has been paid to levels of trust in online sources of health information. The objective of this study was to investigate levels of trust in various sources of health information (interpersonal channels, traditional media, and Internet media), and to examine the predictors of trust in health information available on the Internet. METHODS: A questionnaire was administered to 1,300 people (20 years of age or older), evaluating levels of trust in various sources of health information. RESULTS: The highest level of trust was expressed regarding interpersonal channels, with hospital physicians regarded as the most trusted source of information age and income showed an association with trust in online information sources. Elderly people were not likely to trust Internet news sources, and high incomes were found to be strongly associated with trust in online sources of information overall. CONCLUSIONS: Public health organizations must consider the predictors for trust in various sources of information in order to employ appropriate media when targeting vulnerable individuals or developing messaging strategies for health professionals.

Perceptions of Cancer Risk and Cause of Cancer Risk in Korean Adults / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: The aims of the present study were to assess the prevalence of perceived risk for cancer; to explore associations between sociodemographics and family history of cancer and perceived cancer risk; to identify perceived cause of cancer risk; and to examine the associations between sociodemographics and family history of cancer and perceived cause of cancer risk. MATERIALS AND METHODS: This cross-sectional study was conducted among 1,009 participants aged 30-69 years, selected from a population-based database in October 2009 through multiple-stratified random sampling. Information was collected about the participants' perceived cancer risk and perceived cause of cancer risk. RESULTS: Overall, 59.5% of the respondents thought they had the chance of developing cancer. Female sex, younger age, lower income, and family history of cancer were positively associated with perceived cancer risk. The most important perceived cause of cancer risk was stress. There was a difference between sociodemographics and family history of cancer and perceived cause of cancer risk. CONCLUSION: Factors affecting perceptions of cancer risk and cause of cancer risk need to be addressed in risk communications. The results provide important directions for the development of educational strategies to promote awareness and self-appraisal of cancer risk and risk factors.

A Comparison of Clinical Oncologists and Family Physicians toward Complementary and Alternative Medicine in South Korea: Perceptions, Attitudes and Physician-Patient Communication / 가정의학회지

BACKGROUND: Although, its efficacy is unclear, the application of complementary and alternative medicine (CAM) is increasing among patients worldwide. The physician's role is very important to help patients understand and use CAM properly. The aim of this study is to examine the perceptions, attitudes and physician-patient communication of about CAM in two distinguished specialty physicians. METHODS: A web-based survey was performed to list oncologists and family physicians in Korea between May 2007 and July 2007. E-mails were sent to total of 5,429 physicians and 547 physicians replied on survey (response rate: 10.1%). Of them, 500 participants comprising 174 clinical oncologists and 326 family physicians were involved in this study. The study questionnaire consisted of 26 questions including questions about general characteristics of CAM and intentions of introduction and education to their patients. RESULTS: Of 500 physicians, males were 73.4%, and 82.0% were middle-aged 30-49. Family physicians had more interest than oncologists about CAM (79.5% and 57.5%, respectively). In addition to, family physicians preferred introducing CAM to their patients than oncologists (34.1% and 18.4%, respectively). Almost 85% of the oncologists and family physicians thought that it was necessary to introduce CAM to their patients. However, 60.2% of them had hesitated their practice because 70.3% of them did not have sufficient knowledge in CAM. Both specialty physicians responded that usefulness of CAM information when regarding practice, should contain evidence-based evaluation (59.2%) and consensus guideline (37.0%). CONCLUSION: The results of this study showed that most physicians did not have sufficient information regarding CAM (87.2%). The result implies that evidence based information on complementaryand alternative medicine should be offered in the national level to improve communication between physicians and patients.

Factors Influencing the Intention to have Stomach Cancer Screening / 예방의학회지

OBJECTIVES: The purpose of this study was to identify the factors influencing the intention to have stomach cancer screening using the theory of planned behavior (TPB) in Korea. METHODS: For this population-based study, 1,535 adult respondents (aged 40 to 70 years) were recruited using multi-stratified random sampling and a face-to-face administered questionnaire. This study was based on Ajzen's theory of planned behavior. Intentions were divided into three scenarios for fee payment in the next two years: (1) free of charge, (2) co-payment, and (3) full charge. Multiple linear regression was used to identify the factors influencing the intention to have stomach cancer screening. RESULTS: Perceived behavioral control and attitude toward stomach cancer screening were significant predictors of the intention to have stomach cancer screening. However, subjective norm only influenced the intention to have stomach cancer screening with full charge in the next two years. CONCLUSIONS: The results suggest that attitude and perceived behavioral control are likely to contribute toward increasing the intention to have stomach cancer screening. Especially, perceived behavioral control is a good predictor. Because the study subjects were nation wide residents, the study results can be generalized.
