The Association of Relative Handgrip Strength with Impaired Fasting Glucose among Koreans Aged more than 20 Years Old

Background@#The prevalence of impaired fasting glucose (IFG) in Korea is increasing. Few studies have investigated the relationship between handgrip strength (HGS) and type 2 diabetes among Koreans; however, no study has investigated the relationship between IFG and HGS among Koreans. Therefore, we examined the relationship between relative IFG and HGS to evaluate HGS as a marker of prediabetes. @*Methods@#This cross-sectional study analyzed data from participants aged 20 years or older (n=9,190) who did not have diabetes and had had their body mass index, fasting plasma glucose (FPG), and HGS measured in the 2016–2017 Korea National Health and Nutrition Examination Survey. The association between relative HGS and IFG was analyzed using complex sample logistic regression analyses after adjusting for age, education, strengthening exercise, aerobic exercise, smoking, excessive drinking, and chronic diseases. @*Results@#The prevalence of IFG was 31.5 (0.9)% and 19.6 (0.7)% for men and women, respectively. According to the increase in quartile of relative HGS, FPG and HbA1c significantly decreased in both men and women (Ptrend<0.001). In multivariate logistic regression, the odds of IFG significantly decreased with the increase in quartile of relative HGS in both men and women (Ptrend=0.001 for men, Ptrend=0.002 for women). @*Conclusion@#This population-based, nationally representative study suggests that higher relative HGS is associated with a decreased risk of IFG for both men and women.

E-cigarette from the point of view of harm reduction

One person dies every six seconds from a smoking-related disease and this problem is likely to worsen. While many people try to quit smoking on their own or with using medicinal products, many of them fail. There is an ongoing debate within the public health community about e-cigarettes on whether they have a potential role in smoking cessation, whether their use can reduce harm for individual users, whether the widespread use of these devices has the potential to reduce or increase population-level harm, and how best to regulate e-cigarette use to minimize both individual and population-level harm. Although the long-term effects of e-cigarette use among smokers and non-smokers are not known, nicotine aerosol produced from a solution, rather than from burning tobacco, releases fewer harmful substances than cigarette smoke does. Some experts advocate wider availability and softer regulations regarding e-cigarette use and perceive them as having the potential to help smokers quit or switch to a harm-reducing means of consuming nicotine. Based on scientific evidence on e-cigarettes, this article explores its pros and cons to public health in order to guide practice, policy, and regulation through reviews of debate articles. ‘Quit or die’ is no longer the only option for those who cannot quit. Safer nicotine products offer another way. There is substantial international and independent evidence that these products are safer than cigarettes.

Comparison of Information between Domestic and International Web-Pages for E-Cigarettes: What Are the Differences between Naver and Google?

BACKGROUND: Online health information can influence consumers to make informed decisions. There are conflicting messages online about health concerns on the use of e-cigarettes. We aimed to investigate differences in those messages through Naver and Google's English versions, which are the most representative portal sites in Korea and in the world. METHODS: We reviewed the top 100 web pages related to health effects of e-cigarettes on Naver and Google in May 2018. Two medical doctors sorted the web pages into three groups as positive, negative, and mixed messages for e-cigarettes, as well as two groups based on the relative safety of conventional smoking versus e-cigarettes. RESULTS: There were 10 and 27 positive, 65 and 45 negative, and 25 and 28 mixed messages on Naver and Google, respectively. There were 15 messages on Naver and 53 on Google that considered e-cigarettes safer than conventional cigarettes. The most frequent topics were toxicity (71%) and diseases (22%) on Naver. Google provides topics of health concerns for young people, including gateway effect (47%), diseases (35%), and toxicity (25%). Particularly, harm reduction which was not present on Naver, came up on Google as 24%. CONCLUSIONS: We found that Naver provides more negative messages on e-cigarettes than does Google, which means that Koreans are exposed more to negative information on e-cigarettes than are foreign people who use Google. In future, more open discussions about harm reduction should be conducted to resolve the imbalance in information regarding health effects of e-cigarettes in Korea.

Physicians' Perspectives on the Smoking Cessation Service for Inpatient Smokers

BACKGROUND@#Smoking cessation services for inpatients can be provided effectively through interdisciplinary collaborations. Physicians could play a central role in smoking cessation counseling and treatment for recovery from illness and health promotion of the inpatient. This study aimed to investigate the perspectives of physicians on inpatient smoking cessation services.@*METHODS@#We conducted one personal and two focus group interviews with clinical faculties at a university hospital in Seoul and a university hospital in Chungnam using semi-structured questionnaires. Interviews were recorded, and the transcribed verbatim was analyzed qualitatively.@*RESULTS@#The physicians recognized the need for inpatient smoking cessation services and recognized that smoking cessation was effective when the patient had a smoking-related illness such as respiratory or cardiovascular disease Additionally, the physicians recognized the need for hospital management to support smoking cessation in hospitalized patients and recognized that it was effective to have a dedicated workforce with a smoking cessation coordinator. There was support from four types of physicians in the smoking cessation program: active participant, passive supporter, passive ignorer, and active refuser.@*CONCLUSIONS@#The physician is important for the effective implementation of inpatient smoking cessation services. A dedicated team for the smoking cessation of the inpatient, the establishment of evidence-based data on the effectiveness of the inpatient smoking cessation services, and development of customized smoking cessation services will be necessary to strengthen the role of physicians.

Consensus guidelines for the definition of the end stage of disease and last days of life and criteria for medical judgment

In Korea, the Hospice, Palliative Care, and Life-sustaining Treatment Decision-making Act was enacted in February 2016 in order to ensure that the patient's self-determination in end-of-life care processes is respected. To enhance physicians' understanding of this act and to provide proper criteria for medical judgment in variety of clinical settings, consensus guidelines were published in November 2016. In this article, the characteristics of these guidelines and related issues regarding the definitions of ‘the end stage of disease’ and ‘last days of life’ and the criteria for medical judgment are presented and summarized. According to the guidelines, the term ‘end stage of disease’ refers to a state in which there is no possibility of a fundamental recovery and the symptoms are expected to worsen within months. The terms ‘the last days of life’ and ‘the final days of life’ refer to a state in which, despite treatment, the patient's condition is worsening and death is impending, with no possibility of recovery. The attending physician and another relevant specialist should both judge a patient's medical condition as either ‘end stage of disease’ for hospice/palliative care or ‘the last days of life’ for dying patient care according to the law. Caregivers should provide appropriate medical information to eligible patients for palliative or ‘end stage of disease’ care through advance care planning. Therefore, it is critically necessary that caregivers understand the legitimate process of hospice/palliative and dying patient care based on the patient's wishes and best interests. Physicians should apply these consensus guidelines to eligible patients considering their clinical course and the patients' wishes.

Issues of new types of tobacco (e-cigarette and heat-not-burn tobacco): from the perspective of ‘tobacco harm reduction’

E-cigarettes, heat-not-burn (HNB) tobacco, and other new types of tobacco products are emerging in Korea. These products are particularly popular among smokers who are looking for less harmful means of tobacco consumption, and are highly relevant for existing tobacco control policies. E-cigarettes, which are electronic devices designed to allow the user to inhale nicotine as a vapor, are controversial in terms of their safety and effects on smoking cessation, as a variety of harmful substances have been detected in e-cigarette vapor. Due to policy differences in tobacco harm reduction, the regulations on e-cigarettes differ from country to country, and domestic regulations regulate e-cigarettes in a manner similar to conventional cigarettes. In contrast, HNB tobacco was introduced in Korea in June 2017, and is rapidly expanding in the market, as active marketing campaigns seek to communicate to consumers that HNB tobacco use involves no tar and is less harmful to health. However, the World Health Organization and several professional groups have argued that based on independent studies not supported by tobacco companies, HNB tobacco should be regulated in the same way as conventional cigarettes because there is no evidence that HNB tobacco is less harmful. Clinicians need to expand their understanding of new tobacco products so that they can provide appropriate counseling.

Factors Affecting Adherence to Antihypertensive Medication / 가정의학회지

BACKGROUND: Hypertension is a major contributor to the global disease burden of cardiovascular and cerebrovascular disease. The aim of this study was to determine demographic and clinical factors associated with adherence to antihypertensive medication. METHODS: From August 2012 to February 2015, we recruited 1,523 Korean patients with hypertension who visited family physicians. The study was conducted in 24 facilities located in urban and metropolitan areas. Of these facilities, two were primary care clinics and 22 were level 2 or 3 hospitals. Adherence was assessed using the pill count method; a cut-off value of 80% was used as the criterion for good adherence. Sociodemographic and lifestyle factors were compared between the adherent and nonadherent groups using the chi-square test for categorical variables and t-test for continuous variables. Binary logistic regression analysis was performed with medication adherence as the outcome variable. RESULTS: Of the 1,523 patients, 1,245 (81.7%) showed good adherence to antihypertensive medication. In the multivariate logistic analysis, age ≥65 years, exercise, treatment in a metropolitan-located hospital, being on ≥2 classes of antihypertensive medication and concomitant medication for diabetes, and a family history of hypertension or cardiovascular diseases were associated with good adherence. Patients who had a habit of high salt intake were less adherent to medication. CONCLUSION: Multiple classes of antihypertensive medications, concomitant medication, and exercise were associated with good adherence to antihypertensive medication, and high salt intake was associated with poor adherence to antihypertensive medication. These factors should be considered to improve hypertension control.

Delphi Survey for Designing a Intervention Research Study on Childhood Obesity Prevention / 가정의학회지

BACKGROUND: The prevalence of childhood obesity in South Korea has increased owing to economic improvement and the prevailing Westernized dietary pattern. As the incidence of chronic diseases caused by obesity is also expected to increase, effective interventions to prevent childhood obesity are needed. Therefore, we conducted a Delphi study to determine the priorities of a potential intervention research on childhood obesity prevention and its adequacy and feasibility. METHODS: The two-round Delphi technique was used with a panel of 10 childhood obesity experts. The panelists were asked to rate “priority populations,”“methods of intervention,”“measurement of outcomes,”“future intervention settings,” and “duration of intervention” by using a structured questionnaire. Finally, a portfolio analysis was performed with the adequacy and feasibility indexes as the two axes. RESULTS: For priority populations, the panel favored “elementary,”“preschool,” and “middle and high school” students in this order. Regarding intervention settings, the panelists assigned high adequacy and feasibility to “childcare centers” and “home” for preschool children, “school” and “home” for elementary school children, and “school” for adolescents in middle and high school. As the age of the target population increased, the panelists scored increasing numbers of anthropometric, clinical, and intermediate outcomes as highly adequate and feasible for assessing the effectiveness of the intervention. CONCLUSION: According to the results of the Delphi survey, the highest-priority population for the research on childhood obesity prevention was that of elementary school students. Various settings, methods, outcome measures, and durations for the different age groups were also suggested.

Patients' Perceived Quality of Family Physicians' Primary Care with or without 'Family Medicine' in the Clinic Name / 가정의학회지

BACKGROUND: Patients' perspectives of family medicine according to the physician's identity and role as a primary-care specialist need to be investigated. This study was conducted to investigate the perceived quality of the primary care of family medicine clinics as assessed by patients in a community setting. METHODS: Patients (or their guardians) visiting nine community family medicine clinics were surveyed using the Korean Primary Care Assessment Tool from April 2014 to June 2014. The scores of the Korean Primary Care Assessment Tool domains were compared according to the clinics' designation (or not) as 'family medicine' and the patients' recognition (or not) of the physicians as board-certified family medicine specialists. RESULTS: A total of 196 subjects responded to the questionnaire. They assessed the community clinics' quality of primary care as moderate to high. Of the clinics, those that were not designated as family medicine scored higher than those that were designated as family medicine (P<0.05). The group of patients that recognized a clinic as that of a board-certified family medicine specialist awarded higher scores than the non-recognition group in the domains of coordination function and personalized care (P<0.05). CONCLUSION: The moderate to high scores for the community family medicine clinics' quality of primary care are encouraging. It seems that patients' recognition of the family physician's role and of the physician-patient relationship has a significant influence on their assessment of the quality of primary care.

Compliance and Effectiveness of Smoking Cessation Program Started on Hospitalized Patients / 가정의학회지

BACKGROUND: Varenicline is now very useful medication for cessation; however, there is only little result of researches with varenicline for cessation of hospitalized patients. This research attempted to analyze the cessation effect of medication and compliance of hospitalized patients. METHODS: This research included data for 52 patients who were prescribed varenicline among 280 patients who were consulted for cessation during their admission period. This research checked whether smoking was stopped or not after six months and analyzed their compliance, the factors for succeeding in smoking cessation. RESULTS: One hundred and ninety hospitalized patients participated in smoking cessation counseling among 280 patients who included consultation from their admission departments. And varenicline was prescribed for only 80 patients after counseling. Nineteen smokers were successful in smoking cessation among 52 final participants representing the rating of success of 36.5%. The linkage between compliance of varenicline and rate of smoking successful has no statistical significance. The factors for succeeding in smoking of hospitalized patients are admission departments, diseases, and economic states. CONCLUSION: Smoking cessation program has low inpatient compliance. Cooperation of each departments is very important for better compliance. Success rate of cessation was relatively high (36.5%). Cessation attempt during hospitalization is very effective strategy.

Health-Promotion and Disease-Prevention Behaviors of Primary-Care Practitioners / 가정의학회지

BACKGROUND: In the 1990s the primary focus of medicine was shifted to disease prevention. Accordingly, it became the responsibility of primary-care physicians to educate and counsel the general population not only on disease prevention specifically but health promotion generally as well. Moreover, it was, and is still today, considered important that physicians provide positive examples of health-promotion behaviors to patients. The purpose of this study was to investigate physicians' health-promotion behaviors and to identify the factors that influence them. METHODS: We conducted a postal and e-mail survey of the 371 members of the Physician Association of Cheonan City between May 16th and June 25th, 2011. The questionnaire consisted of 18 items, including questions relating to sociodemographic factors, screening tests for adult diseases and cancer, and health habits. RESULTS: There were 127 respondents. The gender breakdown was 112 men (88.2%) and 15 women (11.8%), and the mean age was 47.8 years. Fifty-nine (46.4%) were family physicians or interns, and 68 (53.6%) were surgeons. Twenty-six percent (26%) were smokers, and 74.8% were drinkers; 53.5% did exercise; 37% had chronic diseases; 44.9% took periodic cancer screening tests, and 72.4% took periodic screening tests for adult diseases. CONCLUSION: It was found that general characteristics and other health-promotion behaviors of physicians do not affect physicians' practice of undergoing periodic health examination.

Comparison of Metabolic Characteristics of Metabolically Healthy but Obese (MHO) Middle-Aged Men According to Different Criteria / 가정의학회지

BACKGROUND: To compare the prevalence and metabolic characteristics of metabolically healthy but obese (MHO) individuals according to different criteria. METHODS: We examined 186 MHO middle-aged men (age, 37.2 years; body mass index [BMI], 27.2 kg/m2). The following methods were used to determine MHO: the National Cholesterol Education Program (NCEP) Adult Treatment Panel III criteria, 0-2 cardiometabolic abnormalities; the Wildman criteria, 0-1 cardiometabolic abnormalities; the Karelis criteria, 0-1 cardiometabolic abnormalities; the homeostasis model assessment [HOMA] criteria (lowest quartile of HOMA). After dividing the overall subjects into two age groups, we compared the prevalence and clinical characteristics between MHO and at-risk groups according to four different criteria. RESULTS: The prevalence of MHO using the NCEP, Wildman, Kaleris, and HOMA criteria were 70.4%, 59.7%, 28.5%, and 24.2%, respectively. The agreement between the groups according to the NCEP and Wildman criteria was substantial (kappa = 0.8, P < 0.001). Among individuals 35 years or younger, and regardless of method, the MHO subjects had significantly lower weight, waist circumference, BMI, body fat percentage, insulin, HOMA, alanine aminotransferase, triglyceride (TG), and TG/high density lipoprotein cholesterol (HDL-C) ratio than the at-risk subjects (P < 0.05); However, among individuals older than 35 years old, and regardless of method, the MHO subjects had different insulin, HOMA, HDL-C, and TG/HDL-C levels than the at-risk subjects (P < 0.05). CONCLUSION: The differences in metabolic profile between MHO and at-risk groups varied according to age. MHO prevalence varies considerably according to the criteria employed. Expert consensus is needed in order to define a standardized protocol for determining MHO.

Quality Improvement Strategies of Medical Ethics Education in Korea / 한양의대학술지

In the past twenty years, medical ethics has emerged as a priority within medical schools in Korea. This article contains important messages about the general overviews and current status, such as the educator, teaching method, and goals of medical ethics education in medical schools. The author suggests ideas of improvement and qualification of the medical ethics education in Korea. There are two points of view regarding the purpose of teaching medical ethics: (1) that it is a means of creating virtuous physicians; and (2) that it is a means of providing physicians with a skill set for analyzing and resolving ethical dilemmas. The field would benefit from further theoretical work aimed at better delineating the core content, core processes, and core skills relevant to the ethical practice of medicine. They are in agreement that a multidiciplinary team of ethicist-philosophers and physicians should teach medical ethics, and ethics education should be integrated longitudinally throughout the 4 years of medical school. Within a few decades the number of Korean medical schools requiring medical ethics has increased in volume. Further progress in ethics education may depend on medical schools' willingness to devote more curricular time and funding to medical ethics for faculty development and resources.

The Efficacy and Safety of a Combined Alendronate and Calcitriol Agent (Maxmarvil): A Postmarketing Surveillance Study in Korean Postmenopausal Women with Osteoporosis / 가정의학회지

BACKGROUND: Combined therapy with alendronate and calcitriol may have additive effects on bone density. An observational study was performed to evaluate the efficacy and safety of Maxmarvil, a combinative agent of alendronate (5 mg) and calcitriol (0.5 microg), and to identify factors associated with efficacy. METHODS: A total of 568 postmenopausal women with osteoporosis were enrolled by family physicians in 12 hospitals. The study subjects took Maxmarvil daily for 12 months. Questionnaires about baseline characteristics, socioeconomic status, and daily calcium intake were completed at the first visit. Adverse events were recorded every 3 months and bone mineral density (BMD) in the lumbar spine was measured using dual-energy X-ray absorptiometry at baseline and after 12 months. We evaluated the efficacy and safety of Maxmarvil, and the factors related to BMD improvement. RESULTS: A total of 370 patients were included in final analysis. The median BMD was 0.81 +/- 0.12 g/cm2 at pre-treatment and 0.84 +/- 0.13 g/cm2 after one year. The average BMD improvement was 3.4% +/- 6.4% (P < 0.05), and 167 (45.1%) patients showed improvement. Factors associated with improved BMD were continuation of treatment (odds ratio [OR], 2.41; 95% confidence interval [CI], 1.15 to 5.07) and good compliance (OR, 2.54; 95% CI, 1.29 to 5.00). Adverse events were reported by 35 of the 568 patients, with the most common being abdominal pain and dyspepsia. CONCLUSION: Maxmarvil was found to be safe, well tolerated and effective in osteoporosis treatment. Continuation of treatment and good compliance were the factors associated with efficacy.
