Contextual effects of social integration and disintegration on health status: evidence from South Korea.

BACKGROUND: Many studies have shown that various social integration variables represented by social capital are beneficial to communities, including collective health. However, the rapid decline in fertility rates and the breakup of familyism in developed countries require a new approach to social disintegration, but the literature is insufficient. Here, we explored the contextual effects of social integration and social disintegration on the health of individuals. METHODS: The research data consist of merged datasets of 6909 respondents who were quota-sampled by approximately 30 people from 229 local governments in Korea. The individual-level independent variable is a social integration measure consisting of 26 questions in four areas. The community-level independent variables are five integral and aggregate variables extracted from 81 indicators. The dependent variable is self-rated health status. Potential confounders are gender, age, annual income, educational attainment, district type, and the number of beds in medical institutions per 1000 people. RESULTS: The results showed that at the individual level, the higher the inclusive attitude of in- and out-of-networks, after adjusting for potential confounders, the less likely the respondent belongs to the unhealthy group (p < 0.001). At the community level, the higher the proportion of single-person households in a community after adjusting for potential confounders, the less likely the respondent belongs to the unhealthy group (p < 0.05). The effect size was 0.22. CONCLUSION: Thus far, social integration has been preferred, with the positive aspects of social capital being emphasized. However, this study shows that in some cases, social disintegration can instead positively influence an individual's health. Therefore, further studies of the various conditions of social context effects on health are necessary.

The Influence of Exposure to Smoking in Movies on Cigarette Cravings among Adolescents: A Contextual Quasi-Experimental Model.

This study explored the socio-contextual characteristics of adolescents that led them to have increased cigarette cravings when exposed to smoking scenes in films. We analyzed online survey data collected from a representative sample of 955 Korean adolescents. Our dependent variable was change in cigarette cravings after watching a smoking scene; independent variables included sex, age, school type, allowance, smoking experience, and parental smoking. We used paired t-tests to identify the differences in cigarette cravings modified by individual characteristics, and we performed logistic regression to explore the influences on these changes in cravings. The high school students investigated herein had significantly stronger cigarette cravings after they watched smoking scenes than they did prior to watching these scenes (t = -5.039, p < 0.001). The cravings were significantly higher after watching the clips among non-smokers (t = -4.264, p < 0.001) and participants who had at least one parent who smoked (t = -2.114, p < 0.05); non-smoking adolescents were also more likely to crave cigarettes after they watched smoking scenes than were smokers (odds ratio = 6.90, p < 0.001). Korean adolescents who did not smoke and those who had at least one parent who smoked showed the strongest cigarette cravings after being exposed to smoking in films. Consequently, more effective prevention strategies should be developed that recognize this tendency when regulating smoking scenes in movies or implementing related campaigns among adolescents.

Digital Health Care and the Fourth Industrial Revolution.

We live in a world where big medical data are being compiled. Many people make use of biometric information gathered by a variety of health care devices linked to smartphones, such as Fitbit devices. In addition, the development of medical information management schemes and the introduction of health information systems have greatly increased the possibility of using medical records stored in medical institutions. With the development of sensor technology and analytical capabilities, we have gained new knowledge through big data, stemming from the collection of data that was not important in the current medical area. Digital health care is moving toward creating value while creating utility as well based on data collected beyond the level of those collected by sensors. Only organizations that have quickly entered the market and accumulated data and have already developed advanced algorithms based on the data can be competitive. However, digital health care companies that survive in the market will lead the change and will reorganize the health care sector. In addition, a big data-based health care platform can help increase the number of e-patients through patient participation.

Global Challenges to Human Immunodeficiency Virus Prevention.

Because of the high prevalence of human immunodeficiency virus (HIV), men who have sex with men (MSM) is socially branded in many countries, and epidemiological approaches have become difficult for this group. This study reviewed the clinical development and political challenges associated with HIV infection. Organizing and disseminating clinical medical advances can help us eliminate social stigmas and the dishonor linked to MSM. In addition, dealing with the worldwide infection problem of MSM can help to reestablish international joint confrontation and political agendas to promote disease eradication efforts. In many countries, socioeconomic problems are not related to increased numbers of HIV infections. Improving social issues such as human rights and economic problems depending on the circumstances of each country should help reduce the risk of HIV infection. The stigmas affecting HIV-infected persons vary greatly depending on the country. It is a serious problem in many countries, including Korea. It is also an important obstacle to those who work to prevent HIV infection. This stigma is a factor that prevents HIV patients from being diagnosed and treated at an early stage. Delayed diagnosis of and delayed treatment for HIV-infected people not only worsen an individual's prognosis but also can spread HIV socially. Efforts to reduce the stigma are necessary not only for individuals with HIV but also for public health.

Effects of Maternal Decisional Authority and Media Use on Vaccination for Children in Asian Countries.

Background and objectives: It is now accepted that vaccination is a critical public health strategy in preventing child morbidity and mortality. Understanding factors that promote vaccination is a critical first step. The objective of this study was to investigated associations of maternal decisional authority and media use on vaccination for children in six South and Southeast Asian countries. Materials and Methods: Data come from demographic and health surveys conducted in Bangladesh, Cambodia, Indonesia, Nepal, Pakistan, and the Philippines between 2011 and 2014 (N = 45,168 women). Main outcome variables were four types of basic vaccination for children. Independent variables were maternal decisional authority and media use. Hierarchical multivariable regression analyses were performed to examine associations. Results: Children of mothers who had more decisional authority were more likely to be vaccinated compared to those participants who did not have such authority. The likelihood to have their children vaccinated was higher among women who frequently used media than those who did not use media. Conclusions: Maternal decisional authority and media use are related to improved vaccination for children. To increase vaccination rates in developing countries in South and Southeast Asia, programs and policies that promote maternal decisional authority and the use of media for health need to be implemented to help families and local communities.

Zolpidem Overdose: A Dilemma in Mental Health.

Sleeping pills are one of the most common drugs taken by adults when afflicted by insomnia. Adverse effects of pharmacotherapy, however, should not be overlooked, and monitoring is needed to check for an overdose of sleeping pills. We reviewed zolpidem overdose and patient suicide with benefits and disadvantages of pharmacotherapy. Cases of adverse effects concerning the central nervous system, including delirium and hallucination, as well as abnormal behavior during sleep, are commonly reported among patients who have taken zolpidem for more than 1 year. The serious problem of long-term prescription to medication can lead to a higher mortality rate of insomniac patients. An alternative to medication for treating insomnia is cognitive behavioral therapy, which can improve sleeping habits. Cognitive behavioral therapy induces patients to recognize and change the negative thoughts that affect their sleep. Medical providers should be aware of the adverse effects of sleep inducers and provide sufficient information to their patients about them. When establishing treatment plans, they should encourage patients to make the proper decisions and try to reduce the adverse effects of any medication as much as possible.

Challenges of Vaccinations in the Era of New Media Communication.

Active discussions are underway on whether or not the absence or insufficiency of communication is a decisive factor affecting hesitancy with regard to vaccines. Low-quality services such as insufficient communication can lead to an increase in the population postponing vaccinations in countries without deficiencies in vaccine procurement. This study examines the strategies and tasks of health communication in relation to vaccinations. Social networking services (SNSs) are major channels of health communication in responding to infectious diseases. New videos posted on the Internet attract considerable amounts of attention from SNS users and increase traffic to certain Web sites. However, most of these videos are produced and uploaded by nonexperts. Although medical institutions have striven to convey key messages concerning infectious diseases to the public, in the SNS space, contents differing from scientific evidence acknowledged as the established theory have been disseminated as well. Social networking services can also amplify any unnecessary anxiety about infectious diseases. In addition, as false information about vaccines is circulated or conflicting information surfaces, the confusion of the general public is aggravated and the phenomenon of vaccine hesitancy can be intensified. Therefore, it is necessary to improve vaccination acceptance through strategies that integrate new and old media. At the same time, we need to establish customized public health education for the public, vulnerable groups, and experts.

Social Capital, Community Capacity, and Health.

The capacity to practice health behavior is different for each individual. Community capacity and social capital deal with understanding the relationship between community members and with the factors that promote or delay collective activities. This study examines existing literature in relation to social capital, health, and community capacity. Bonding social capital shows the average value of the extent to which individuals trust each other and participate in groups, whereas bridging social capital shows the average value of the extent to which individuals participate in different formal groups. Community capacity seeks mutual cooperation based on trust, and cohesion minimizes community problems, and it has become evident that such capacity is a useful tool for health improvement.

Associations between media use and health information-seeking behavior on vaccinations in South Korea.

BACKGROUND: Although vaccinations are critical for preventing emerging infectious diseases, scant research has been conducted on risk communication. With socio-economic characteristics, health behavior, and underlying diseases under control, we investigated associations between media use, health information-seeking behavior, health information type, and vaccination in the population. METHODS: This study relied on a national survey of Korean adults (n = 1367). Participants were adult males and females age 20 and older. Web and face-to-face surveys were conducted throughout July 2014. The main outcome was vaccination (categorized as yes or no). Independent variables were time spent on media, frequency of health information-seeking behavior, and types of health information sought. RESULTS: Controlling for co-variates, logistic regression analysis was conducted to identify factors that influence Korean adults being vaccinated. Results revealed that accessible information about emerging infectious diseases, listening to the radio, and reading the newspaper were associated with increased odds of being vaccinated. Active seeking health information as well as being female and of higher socio-economic status were positively correlated with Korean adults being vaccinated. CONCLUSION: It is critical to promote health information-seeking behavior and use diverse media channels to increase acceptance and awareness of emerging infectious diseases and vaccinations. Because there are differences in vaccination awareness depending on social class, it is critical to reduce communication inequality, strengthen accessibility to vaccinations, and devise appropriate risk communication strategies that ensure Korean adults receive vaccinations.

Conflicting Online Health Information and Rational Decision Making: Implication for Cancer Survivors.

Although people in the social media age can access health information easier, they have difficulty judging conflicting rational information or summarizing the large amounts of health information available. Conflicting health information occurs when contrary assertions or information about a certain health issue comes from different information sources. This study examined the background knowledge and the current phenomenon of why conflicting health information occurs in real-world conditions. We also reviewed causes and solutions by reviewing the literature. In particular, we recommend a method that solves problems that patients have including cancer survivors who cannot themselves be active in seeking health information. Thus, we categorized the specific types of conflicting health information and analyzed the sociodemographic factors and information carrier factors that have an impact on the health information-seeking behavior of individuals.

Exploring socio-contextual factors associated with male smoker's intention to quit smoking.

BACKGROUND: Programs to encourage smokers to quit smoking tobacco have been implemented worldwide and are generally viewed as an effective public health intervention program. However, few studies have examined the social factors that influence a smoker's intention to quit smoking. This study investigated the socio-contextual factors that are associated with the intention to quit smoking among male smokers in South Korea. METHODS: Data were obtained from a 2014 nationally representative panel that examined the influences of mass media on the health of the Korean population. Members of this panel were recruited using a mixed-method sampling and a combination of random digit dial and address-based sampling designs. Survey questions were based on those used in previous studies that assessed the effects of social context, including mass media and social capital, on health. Multivariate logistic regression analyses of the answers of 313 male smokers were undertaken. RESULTS: Male smokers who participated in community-based activities were 2.45 times more likely to intend to quit smoking compared to male smokers in general (95 % confidence interval [CI]: 1.25-6.82). In addition, male smokers who participated in informal social gathering networks were 2.38 times more likely to intend to quit smoking compared to male smokers in general (95 % CI: 1.11-5.10). Moreover, male smokers with high smartphone use were 1.93 times more likely than smokers with low smartphone use to intend to quit smoking within one year (95 % CI: 1.07-3.46). CONCLUSIONS: A supportive environment that enables male smokers to access beneficial health information and that encourages them to quit smoking is necessary for a stop-smoking program to be effective. The result of this study contribute to establishing a new smoking control policy by identifying socio-contextual factors related to the intention to quit smoking.

Effects of public and private health insurance on medical service utilization in the National Health Insurance System: National panel study in the Republic of Korea.

BACKGROUND: Moral hazard or utilization hazard refers to the phenomenon during which patients overuse medical services under national health insurance (NHI) because the services are free or the patients are required to pay only a portion of the utilization costs. The aim of this study is to investigate how NHI and private health insurance (PHI) systems influence increases in health care utilization rates. METHODS: We designed a longitudinal study to examine the utilization of healthcare services between those insured with NHI or PHI and uninsured Koreans using nationally representative four-year panel data from 13,798 participants. This study was conducted using hierarchical multivariate Poisson regression analyses in which covariates and interaction terms are applied after adjusting for the heterogeneous treatment effect. RESULTS: After adjusting covariates including disease status, lower income Koreans who were covered by medical aid were respectively 2.26 and 1.23 times more likely to receive inpatient care and outpatient care than those who were covered by NHI. When the interaction term of type of insurance was included in the model, those were covered by both medical aid and PHI were respectively 2.38 and 1.25 times more likely to receive inpatient care and outpatient care than those who were covered by only NHI. CONCLUSIONS: The moral hazard behind insurance membership, depending on how NHI maintains policies to confer benefits, may give rise to differences in medical utilization. This phenomenon must be closely monitored to find a way to reform NHI when the rights of medical service consumers are solidified through PHI.

Challenges of Multimorbidities in the Era of an Aging Population.

The health care system introduced a reimbursement system based on the existing care when the prevalence rate of acute diseases was still. However, the types of diseases in developed countries are mostly noncommunicable diseases such as cancer or vascular disease, and thus, it impossible to fully recover from these chronic diseases. The increase in noncommunicable diseases is related to unhealthy lifestyle habits such as smoking, heavy drinking, and lack of exercise. Thus, the health care system is changing by improving the prevention of diseases and promoting healthy lifestyles. However, multimorbidities have emerged as an important concept in this process. In countries where the population is rapidly aging, those who have multimorbidities have become a burden to the health care system's revenue, manpower, and service quality. Therefore, health care reform to cope with those who are aging and have multimorbidities is necessary to establish. Reform measures can consist of the following suggestions. First, proper medical guidelines for multiple diseases need to be developed. Second, professional manpower should be trained. Third, the reimbursement system should be improved to relieve those with multimorbidities. Fourth, disease prevention services should be improved. Finally, instruments to measure health care service quality for chronic disease need to be developed.

Consumer Health Informatics: Promoting Patient Self-care Management of Illnesses and Health.

Consumer health informatics (CHI) is propelling important changes for medical providers and the lives of patients through information and communications technology. Independently, medical consumers seek, collect, and use health information for decision making. However, when constructing a CHI-based medical platform, high technology must be applied in a fully understandable and usable format for both health care providers and consumers. This study examines the present status of CHI and its effect on medical consumers. For the development of CHI, we discuss the need for tailored health communications and capacity building with chronic patients at the medical center. First, empowerment is a key characteristic needed for medical consumer health care management. However, promoting patient self-care management of illnesses and health is necessary to create conjugation where cooperation with medical service providers is possible. Also, establishing a health care delivery system that will support cooperation is necessary. Second, tailored health communications can uniquely construct the health information of patients, which prevents unnecessary or excessive information from leading patients to confused and inappropriate decisions. Ultimately, through the present environment of health communication, the innovation of a consumer health care information system has become the tide of the times and the positive effect of improved health can be expected.

Exploring Social Quality and Community Health Outcomes: An Ecological Model.

Quality of life is widely used as a measure of individual well-being in developed countries. Social quality (SQ), however, describes how favorable the socioenvironmental components are that impact the life chance of an individual. Despite the associations between SQ, including institutional capacity and citizen capacity, and other community indicators, the impact of SQ on community health status has not been fully examined. This study investigated the interrelationships among institutional capacity, citizen capacity, and their associations with community-level health indicators such as mortality and suicide among 230 local governments in South Korea. Under the principles of conceptual suitability, clarity, reliability, consistency, changeability, and comparability, a total of 81 SQ indicators were collected, and 19 indicators of the 81 indicators were selected. The 19 indicators were transformed by the imputation of missing values, standardization, and geographic information system transformation. It was found that the health outcome of local government was superior as social welfare, political participation, and education were higher. According to the result of the regression analysis based on the regional type, social welfare had the most influence on the health level of local government in both metropolises and small-/medium-sized cities. In addition, education and political participation had a positive effect on the health indicator of local metropolis government. However, SQ indicators did not have any meaningful influence at the county level. Therefore, small- and medium-sized cities need to promote the collective health of the local government through improving social welfare, and metropolises need to consider the complex relationship among other indicators while increasing the level of social welfare and education. Meanwhile, counties need to develop health indicators that reflect aged population characteristics and social environment of rural areas. Therefore, fundamental social welfare benefits need to be guaranteed while improving SQ capacities in order to improve the health status of local governments.

Task conflicts and exclusive professionalism in nursing in South Korea.

Task conflicts among medical professions are essential problems to be solved in health care organizations. This study examined job conflicts between practical nurses (PNs) and registered nurses (RNs) in their duties and tasks with representative panelists from South Korea. This qualitative study used the Dacum Task Analysis process. Subject-matter experts in practical nursing were recruited utilizing stratified sampling: Ten experts developed job descriptions of PNs, and 20 validated the descriptions. The on-site tasks and duties of the PNs were measured by means of Dacum, and the results were reviewed by RNs using 3 focus-group interviews. The job description of PNs consisted of 10 duties and 117 tasks, overlapping with some tasks of RNs. Core tasks performed by PNs, such as invasive activities, led to task conflicts between the 2 groups, as these activities were regarded as the inherent duty of nursing professions. Thus, the RNs did not concede the expanded job scope of the PNs in terms of exclusive professionalism. To reduce task conflict, there is a need for the balanced development of nursing professionalism.

Determinants of social quality and their regional disparities: an integrated approach for health equity in South Korea.

Quality of life was originally included in the concept of social quality (SQ), which refers to the possibility of manifesting the life chance possessed by each individual and the consequences resulting from restricting such possibility. Social quality describes how favorable the socioenvironmental components are that impact the possibility of an individual's life. Despite the close relationship between community capacity and SQ, the components and regional disparities of SQ have not yet been examined. This study identified community-based distribution and disparities of SQ in South Korea, including health indicators. Standardized methods of SQ were used to examine the interrelationships among institutional capacity, citizen capacity, and their associations with population-based health indicators. Under the principles of conceptual suitability, reliability, clarity, comparability, and changeability, a total of 18 SQ indicators were collected, then transformed by European Social Survey standardization and Geographical Information System computation. In the results, the hidden structure that determined the distribution of the SQ indicators was the financial independence and average length of residence. Financial independence indicated the size of the budget that each local community controls was out of the total budget. The average length of residence showed a reverse-U-shape relation to the mutual supports of the residents. The regional distribution of the SQ indicators largely differed from the local economic index or health indicators. Disparities in SQ indicators are likely to arise from the degree of urbanization and the degree of citizens' cohesiveness. Therefore, it is necessary to analyze in-depth cases of both local government with high SQ indicators in all fields and those with low SQ indicators in all fields. In addition, there is a need to elucidate the structural causes and backgrounds that produce disparities in SQ, thus lowering disparities among regions, and to develop policies that will promote the overall and continuous improvement of SQ.

Behavioral Predictors Associated With COVID-19 Vaccination and Infection Among Men Who Have Sex With Men in Korea.

OBJECTIVES: This study investigated the impact of socioeconomic factors and sexual orientation-related attributes on the rates of coronavirus disease 2019 (COVID-19) vaccination and infection among men who have sex with men (MSM). METHODS: A web-based survey, supported by the National Research Foundation of Korea, was conducted among paying members of the leading online portal for the lesbian, gay, bisexual, transgender, or queer and questioning (LGBTQ+) community in Korea. The study participants were MSM living in Korea (n=942). COVID-19 vaccination and infection were considered dependent variables, while sexual orientation-related characteristics and adherence to non-pharmacological intervention (NPI) practices served as primary independent variables. To ensure analytical precision, nested logistic regression analyses were employed. These were further refined by dividing respondents into 4 categories based on sexual orientation and disclosure (or "coming-out") status. RESULTS: Among MSM, no definitive association was found between COVID-19 vaccination status and factors such as socioeconomic or sexual orientation-related attributes (with the latter including human immunodeficiency virus [HIV] status, sexual orientation, and disclosure experience). However, key determinants influencing COVID-19 infection were identified. Notably, people living with HIV (PLWH) exhibited a statistically significant predisposition towards COVID-19 infection. Furthermore, greater adherence to NPI practices among MSM corresponded to a lower likelihood of COVID-19 infection. CONCLUSIONS: This study underscores the high susceptibility to COVID-19 among PLWH within the LGBTQ+ community relative to their healthy MSM counterparts. Consequently, it is crucial to advocate for tailored preventive strategies, including robust NPIs, to protect these at-risk groups. Such measures are essential in reducing the disparities that may emerge in a post-COVID-19 environment.

Physical Distancing for Gay Men from People Living with HIV During the COVID-19 Pandemic.

The fear of COVID-19 can exacerbate social stigma and prejudice against individuals living with HIV (PLWH). This research delved into the behaviors of MSM (men who have sex with men) who practice physical-distancing from PLWH. Data from 878 respondents were collected through a web survey conducted on Korea's largest LGBT portal site over one month in July 2022. The study examined various independent variables encompassing socioeconomic characteristics, health status, media consumption habits, and homosexual attributes of MSM. The dependent variable assessed was the extent of physical-distancing perceived by MSMs without HIV toward PLWH. The statistical analysis employed nested regression models. In Model I, it was observed that physical-distancing from PLWH decreased as the age and education level of the respondent increased. In Model II, a decrease in physical-distancing was noted among respondents with underlying health conditions. Model III indicated that increased use of traditional media corresponded to greater physical-distancing from PLWH. Lastly, Model IV revealed a reduction in physical-distancing when the respondent was themselves a person living with HIV. This study underscores the existence of physical-distancing toward PLWH within the gay community. Consequently, fostering solidarity and providing support becomes imperative to prevent the isolation of PLWH within this community.

Assessing COVID-19 Vulnerability Among HIV-positive Men Who Have Sex With Men in Korea: The Role of Vaccination and Sexual Behaviors.

OBJECTIVES: Comorbidities increase susceptibility to severe coronavirus disease 2019 (COVID-19) infections, but limited information has been published regarding human immunodeficiency virus (HIV) and COVID-19 co-infections. This study explored the relationships among socioeconomic characteristics, sexual behaviors, and COVID-19 infection rates among Korean men who have sex with men (MSM) who are also living with HIV. METHODS: Data were collected through a web survey aimed at members of the largest gay portal site in Korea, supported by the National Research Foundation of Korea (n=1005). The primary independent variables included COVID-19-related vaccinations and sexual behaviors. The dependent variable was the incidence of COVID-19 infection among respondents during the pandemic. For statistical analysis, hierarchical multiple logistic regression was performed, controlling for potential confounding variables. RESULTS: Model I indicated that older MSM were less likely to contract COVID-19 (adjusted odds ratio [aOR], 0.98; 95% confidence interval [CI], 0.96 to 0.99). Model II demonstrated that HIV-positive MSM were nearly twice as likely to be infected with COVID-19 compared to their HIV-negative counterparts (aOR, 1.97; 95% CI, 1.14 to 3.41). Furthermore, even after accounting for COVID-19 vaccination status in model III, HIV-positive MSM continued to show a higher risk of infection (aOR, 1.93; 95% CI, 1.12 to 3.35). CONCLUSIONS: The findings of this study indicate that HIV-positive MSM are at an increased risk of contracting COVID-19, even when their vaccination status is considered. Therefore, it is essential to prioritize the prevention of COVID-19 infections in HIV-positive individuals by administering appropriate antiretroviral therapy and ensuring adherence to public health guidelines.
