RESUMEN
BACKGROUND: Whether bone mineral density (BMD) is related to the risk of Parkinson's disease (PD) is unclear. OBJECTIVES: The objective of this study was to examine the association between BMD status and incident PD in postmenopausal women. METHODS: We retrospectively examined a nationwide cohort of 272,604 women aged 66 years who participated in the 2009-2012 Korean national health screening for transitional ages. BMD was evaluated using dual-energy X-ray absorptiometry of the central bones. The use of antiosteoporosis medications (AOMs) was assessed. We performed multivariable Cox proportional hazards regression to evaluate the association between BMD and PD risk by calculating hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: During the median follow-up of 7.7 years, 2,884 (1.1%) incident PD cases developed. After adjusting for confounding factors, lower BMD was associated with an increased risk of PD (P for trend <0.001). Individuals with osteoporosis had a 1.40-fold higher HR (1.40, 95% CI: 1.25-1.56) than those with a normal BMD. Sensitivity analyses suggested the associations robust to longer lag periods and further adjustment. These associations were prominent in individuals without AOM use before or after enrollment (P for interaction = 0.031 and 0.014). Increased risks of PD in individuals with osteopenia and osteoporosis who did not use AOMs were attenuated by the medication use during the follow-up period, regardless of previous AOM use. CONCLUSIONS: Lower postmenopausal BMD and osteoporosis were associated with an increased risk of PD. In addition, this association could be mitigated using AOMs. Proper management of BMD in postmenopausal women may help prevent PD. © 2023 International Parkinson and Movement Disorder Society.

BACKGROUND: No validated tool is available to assess patients' perception of physician empathy in Korea. The objective of this study was to establish a Korean version of the Consultation and Relational Empathy (CARE) measure-originally developed in English and widely used internationally-and to examine its reliability and validity. METHODS: The CARE measure was translated into Korean and tested on 240 patients from one secondary care hospital and one tertiary care hospital in Korea. Internal consistency by Cronbach's alpha, exploratory analysis, and confirmatory factor analysis were conducted to verify the 10 items of the Korean CARE measure. RESULTS: The Korean CARE measure demonstrated high acceptability and face validity, excellent internal reliability (Cronbach's alpha = 0.97) and moderate test-retest reliability (Pearson correlation coefficient = 0.53; Spearman correlation coefficient = 0.51). Distribution of scores showed negative skewedness. Corrected item-total correlations ranged from 0.77-0.92, indicating homogeneity. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.949, and Bartlett's test of sphericity was good (χ2 = 3157.11, P < 0.001). Factor analysis yielded a single dimensional structure of physician empathy with all factor loadings exceeding 0.80 and showing excellent goodness of fit. CONCLUSION: This study supports the reliability and validity of the Korean CARE measure in a university hospital setting in Korea.

BACKGROUND: An important barrier to smoking-cessation counseling for physicians is a lack of education at the undergraduate level. Interactive methods such as peer role-play (RP) or modules utilizing standardized patients (SPs) may be effective for medical students to enhance their performance on tobacco cessation counseling. This study compared the effectiveness of a module using SPs to that of a RP module for undergraduate medical students on tobacco cessation counseling. METHODS: This study was conducted over a single week of the family medicine clerkship. One hundred and thirteen fourth-year medical students were randomized into either the SP group or the RP group. A RP module involved a ten-minute encounter between the student doctor and the student patient followed by five minutes of feedback from the observer student using a group developed checklist. In a SP module, each student was asked to interview a SP portraying a smoker with willingness to quit. After the encounter, the SP provided five minutes of direct oral feedback to the student. In both modules, the total intervention lasted three-and-half hours and was supervised by faculty staff. Students' objective structured clinical examination (OSCE) scores were evaluated to determine their tobacco cessation counseling skills. Four evaluation periods were conducted at baseline, postintervention, post-clerkship, and before receiving the Korean medical licensing examination (KMLE). Students' smoking knowledge test scores and counseling self-confidence levels at pre- and post-intervention were also compared. RESULTS: In both groups, post-intervention OSCE scores increased significantly compared to baseline (Cohen's d 0.87, p < 0.001 in SP group; d 0.77, p < 0.001 in RP group). However, there were no differences between the two groups. Students achieved the highest OSCE score for smoking-cessation counseling before the KMLE. After training, student self-confidence and smoking-knowledge test scores increased significantly, regardless of the type of module. Self-confidence was higher in the SP group compared with the RP group (d 0.37, p = 0.01). CONCLUSIONS: Peer role-play may be equivalent to the SP method with regard to knowledge and skills reported during smoking-cessation counseling and SP method may be better in self-confidence. Cost and student self-confidence may be important factors when choosing among the teaching methods for smoking-cessation counseling.

OBJECTIVE: Abdominal obesity is associated with obesity-related health risks regardless of body weight. The present study aimed to determine whether alcohol drinking pattern is associated with abdominal obesity in normal-weight, middle-aged adults. DESIGN: Cross-sectional study using complex sampling design analyses. SETTING: The Korea National Health and Nutrition Examination Survey, which was conducted from 2008 to 2013. SUBJECTS: Normal-weight participants aged 40-69 years with BMI of 18·5-25·0 kg/m2 (n 11 289, 4491 men and 6798 women) were included. Abdominal obesity was defined as waist circumference ≥90 cm for men or ≥85 cm for women. Alcohol drinking pattern was assessed by self-report on questionnaires. RESULTS: Among 11 289 normal-weight participants, 7·9 % (n 379) of men and 7·6 % (n 609) of women had abdominal obesity. Both men and women who consumed a higher quantity of alcohol per drinking occasion had higher odds (OR; 95 % CI) for abdominal obesity compared with individuals who consumed fewer than 2 drinks (1·86; 1·04, 3·32 for ≥10 drinks/typical occasion in men; and 3·28; 1·13, 9·46 in women). Men who binge drink every day had higher odds for abdominal obesity (2·10; 1·21, 3·63). In both sexes, frequency of alcohol drinking was not associated with normal-weight abdominal obesity. CONCLUSIONS: Our study showed that the amount of alcohol drinking per occasion influenced abdominal obesity in normal-weight, middle-aged individuals that may have impacted obesity-related health risks. Healthy alcohol drinking habits need to be controlled for prevention of abdominal obesity even among persons with normal weight.

BACKGROUND AND AIM: We aimed to investigate the association between lower gait speed and cognitive decline over a 3-year period in community-dwelling older people with mini-mental state examination (MMSE) scores of 30 at baseline. METHODS: The study was based on data from 10,003 Koreans aged 60 years or older who completed the National Elderly Survey in both 2008 and 2011. Among them 620 subjects achieved MMSE scores of 30 in 2008. Over a 3-year period, preservation of MMSE score 28 or more was defined as preserved cognition and decrease of three or more points as cognitive decline. A 4-m gait speed was measured at baseline. Data on sociodemographic factors (age, number of schooling years, and household composition), alcohol drinking, current smokers, Korean version of Short form Geriatric Depression Scale score, and self-reported comorbid conditions, were collected. RESULTS: Of 620 (weighted 884) respondents included in the analysis, 208 (52.3 %) of 398 males (weighted 567) and 152 (68.5 %) of 222 females (weighted 317) suffered cognitive decline over the 3-year period. After adjustment, lower gait speed was associated with cognitive decline in males (OR 2.29; 95 % CI 1.07-4.89, P = 0.032). Educational level was a significant risk factor for both men and women (OR 0.86; 95 % CI 0.79-0.93 in males, OR 0.75; 95 % CI 0.65-0.87 in females). Males diagnosed with hypertension (OR 0.44; 95 % CI 0.22-0.88) or male smokers (OR 0.38; 95 % CI 0.19-0.75) were significantly less likely to have cognitive decline. There was no significant association between cognitive decline and gait speed in females. CONCLUSIONS: Higher 4-m gait speed is associated with preservation of cognitive function over time in men, but not in women.

INTRODUCTION: This study sought to assess the association between the changes in nonalcoholic fatty liver disease (NAFLD) and risk of type 2 diabetes in young individuals with prediabetes. METHODS: Data from the Korean National Health Insurance System database were collected from 2009 to 2019 and analyzed in 2022. A total of 446,813 young adults aged 20-39 years with prediabetes who underwent two National Health Screening examinations from 2009 to 2012 were followed up. NAFLD was defined as a fatty liver index≥60 without liver disease or history of alcohol abuse. Multivariable Cox proportional hazards regression was used to calculate the HR and CIs for type 2 diabetes according to NAFLD changes. RESULTS: During a median follow-up of 8.3 years, 26,464 (5.9%) young individuals developed type 2 diabetes. Multivariable adjusted HR of type 2 diabetes according to the NAFLD change was 5.38 (95% CI 5.08-5.70) in individuals with persistent NAFLD when compared to those who never had NAFLD. Even in individuals who were consistently nonobese, resolved NAFLD, new NAFLD, and persistent NAFLD were associated with>3-fold increased risk of type 2 diabetes compared to nonobese individuals without NAFLD. The risk of type 2 diabetes also increased in obese individuals without NAFLD by 2-fold when compared to nonobese individuals without NAFLD. CONCLUSIONS: NAFLD that either existed persistently or ever existed plays a critical role in the development of type 2 diabetes in young adults with or without obesity. Nonobese individuals with NAFLD warrant special attention.

BACKGROUND: Video-recordings review of patient encounters is reported to improve the clinical performance of medical students. However, evidence on specific remediation strategies or outcomes are lacking. We aimed to implement videorecording-based remediation of standardized patient encounters among medical students, combined with preceptor one-on-one feedback or peer group discussion, and evaluate the effectiveness of the two remediation methods using objective structured clinical examination (OSCE). METHODS: Following standardized patient encounters, 107 final-year medical students were divided into two groups based on different remediation methods of video review: (1) precepted video review with preceptor feedback (N = 55) and (2) private video review and subsequent peer group discussion under supervision (N = 52). All students underwent twelve-stations of OSCE both before and after the video review. Students' pre- and post-remediation OSCE scores, self-efficacy level in patient encounters, and level of educational satisfaction with each method were assessed and compared between different video-based remediation methods to evaluate their respective effects. RESULTS: After remediation, the total and subcomponent OSCE scores, such as history taking, physical examination, and patient - physician interaction (PPI), among all students increased significantly. Post-remediation OSCE scores showed no significant difference between two remediation methods (preceptor module, 79.6 ± 4.3 vs. peer module, 79.4 ± 3.8 in the total OSCE score). Students' self-efficacy levels increased after remediation in both modules (both p-value <0.001), with no difference between the two modules. However, students' satisfaction level was higher in the preceptor module than in the peer module (80.1 ± 17.7 vs. 59.2 ± 25.1, p-value <0.001). Among students with poor baseline OSCE performance, a prominent increase in PPI scores was observed in the preceptor-based module. CONCLUSION: Video-based remediation of patient encounters, either through preceptor review with one-on-one feedback or through private review with peer discussion, was equally effective in improving the OSCE scores and self-efficacy levels of medical students. Underperforming students can benefit from precepted video reviews for building PPI.

Background: Prevention and management of metabolic syndrome (MetS) during childhood are crucial. Recently, obesity among children and adolescents has increased with an increase in mothers' working hours. The present study was conducted to determine the relationship between mothers' working hours and MetS in their children. Methods: Data from the 2016-2020 National Health and Nutrition Examination Survey were used, and 2,598 children and adolescents aged 10-18 years were included. Logistic regression analysis was conducted to confirm the association between MetS and mothers' working hours for each risk factor. Linear regression analysis was conducted to confirm the association between mothers' working hours and the number of risk factors for MetS. Results: Abdominal obesity in children was higher when the mothers' working hours were 53 hours or more (odds ratio [OR], 2.267; 95% confidence interval [CI], 1.21-4.25). In the trend analysis, the OR of children's abdominal obesity increased significantly as mothers' working hours increased (P-value <0.05). Additionally, sex-stratified analysis revealed a significant trend between maternal work hours and the presence of MetS in female children (P=0.016). The adjusted OR of the presence of MetS in female children with mothers working 53 hours or more weekly was 6.065 (95% CI, 1.954-18.822). Conclusion: Mothers' working hours were highly correlated with the risk of abdominal obesity in their children. The OR of the presence of MetS significantly increased in female children with mothers having longer working hours compared with those with stay-at-home mothers.
RESUMEN
Background: The 2023 Obesity Fact Sheet aims to present an updated overview of obesity prevalence across all age groups, including children and adolescents. Methods: This study included individuals aged ≥20 years (n=16,941,423 in 2021) who underwent health checkups provided by the Korean National Health Insurance Service between 2012 and 2021. The prevalence of obesity and abdominal obesity was standardized by age and sex using data from the 2010 population and housing census. For children and adolescents (6 to 18 years) (n=884 in 2021), we used the Korea National Health and Nutrition Examination Survey (2012 to 2021), and obesity was defined by the corresponding sex- and age-specific body mass index percentile of 95th or greater based on the 2017 Korean National Growth Chart for Children and Adolescents. Results: The overall prevalence of obesity in 2021 is 38.4% (49.2% in men and 27.8% in women), which is a 1.27-fold increase from 30.2% in 2012. The prevalence of obesity has increased across all age groups, particularly among those aged 20, 30, and 80 years. The prevalence of class III obesity substantially increased from 0.35% (men) and 0.42% (women) in 2012 to 1.21% and 0.97% in 2021, with 3.46- and 2.31-fold increases, respectively. This increase was particularly pronounced in young adults. The prevalence of obesity in children and adolescents has surged from 9.7% in 2012 to 19.3% in 2021, with a greater increase among boys. Conclusion: Our study provides information on the current status of obesity prevalence based on the 2023 Obesity Fact Sheet, emphasizing the urgency of implementing timely strategies to reverse this increasing trend.
RESUMEN
BACKGROUND: To examine the association between glycemic status and all-cause mortality risk among individuals with dementia. METHODS: We enrolled 146,832 individuals aged 40 and older with dementia as identified through the Korean National Health Insurance Service health screening test between 2008 and 2016. Mortality status was evaluated at the end of 2019. Participants were classified into normoglycemia, prediabetes, or diabetes mellitus (DM) categories. The duration of diabetes was noted in those with DM. This study focused on the association between glycemic status and all-cause mortality. RESULTS: The cohort, which was predominantly elderly (average age 75.1 years; 35.5% male), had a 35.2% mortality rate over an average 3.7-year follow-up. DM was linked with increased all-cause mortality risk (hazard ratio [HR] 1.34; 95% confidence interval [CI]: 1.32-1.37) compared to non-DM counterparts. The highest mortality risk was observed in long-term DM patients (≥ 5 years) (HR 1.43; 95% CI: 1.40-1.47), followed by newly diagnosed DM (HR 1.35; 95% CI: 1.30-1.40), shorter-term DM (< 5 years) (HR 1.17; 95% CI: 1.13-1.21), and prediabetes (HR 1.03; 95% CI: 1.01-1.05). These patterns persisted across Alzheimer's disease and vascular dementia, with more pronounced effects observed in younger patients. CONCLUSIONS: Glucose dysregulation in dementia significantly increased mortality risk, particularly in newly diagnosed or long-standing DM. These findings suggest the potential benefits of maintaining normal glycemic levels in improving the survival of patients with dementia.

OBJECTIVE: We investigated the associations between obesity parameters and the risk of hyperuricemia among Korean adults by sex, age, and diabetes mellitus status. METHODS: This study analyzed data from 17,753 adults from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016-2018. Multivariable logistic regression analyses were conducted to examine the associations of body mass index (BMI), waist circumference (WC), and general and abdominal obesity with the risk of hyperuricemia (serum uric acid ≥7.0 mg/dL in men and ≥6.0 mg/dL in women). RESULTS: Of all the participants, 12.7% (n = 2256) had hyperuricemia. The age-adjusted mean serum uric acid levels increased significantly with increasing BMI and WC (P for trend <0.001). The adjusted odds ratios (ORs) of hyperuricemia increased as BMI and WC increased in both sexes (P for trend <0.001). General (OR 1.98, 95% confidence interval [CI]: 1.69-2.32) and abdominal (OR 2.21, 95% CI: 1.89-2.58) obesity in men and general (OR 3.26, 95% CI: 2.60-4.09) and abdominal (OR 3.43, 95% CI: 2.69-4.37) obesity in women were associated with higher risks of hyperuricemia. These associations were prominent in women. The association between abdominal obesity and hyperuricemia persisted after additional adjustments for BMI in both sexes. Significant interactions were observed in younger adults and individuals without diabetes mellitus. CONCLUSION: Increased BMI and WC, and general and abdominal obesity, may be important risk factors for hyperuricemia in both sexes. Women, young adults, and individuals without diabetes mellitus require particular attention to prevent obesity and hyperuricemia.

BACKGROUND: Physical activity is known to prevent several diseases and positively affect mental health. Previous studies have shown that smartphone addiction negatively affects the physical activity of children and adolescents. This study aimed to investigate the relationship between problematic smartphone use and physical activity among adolescents and the related factors using path analysis. METHODS: Using data from the 16th Youth Risk Behavior Web-based Survey from 2020, scores on the Smartphone Addiction Scale-Short Version for Adolescents, physical activity, sex, socioeconomic status (SES), academic performance, depression, smoking, drinking, and sitting time were assessed. Complex sampling and path analyses were performed. RESULTS: Of the total 54,948 students, 25.5% were smartphone risk users, including potential and high-risk users. The direct path coefficients of each factor indicated that female sex (-0.14 for male), low SES (-0.062), high academic performance (0.056), low sitting time for studying purposes (-0.033), high sitting time for non-studying purposes (0.071), and depressive mood (0.130) were related to problematic smartphone use (all P<0.001). Each factor affected problematic smartphone use, and subsequently had a negative effect on the amount of physical activity, with a direct path coefficient of -0.115 (P<0.001). CONCLUSION: In this study, we confirmed that problematic smartphone use among adolescents was negatively associated with performing an adequate amount of physical activity and that various factors, such as sex, SES, academic performance, and sitting time, directly and indirectly affected this relationship.
RESUMEN
Evidence on the association between serum 25-hydroxyvitamin D (25(OH)D) concentration and all-cause and cause-specific mortality in Asians, especially Koreans, is limited. We hypothesized that high concentrations of 25(OH)D are associated with lower all-cause and cause-specific mortality in the general Korean population. This study included 27,846 adults participating in the Fourth and Fifth Korean National Health and Nutrition Examination Survey 2008-2012, followed up through December 31, 2019. Hazard ratios (HR) and 95% confidence intervals (CIs) for mortality from all causes, cardiovascular disease (CVD), and cancer were estimated using multivariable-adjusted Cox proportional hazards regression. The weighted mean serum 25(OH)D of study participants was 17.77 ng/mL; 66.5% had vitamin D deficiency (<20 ng/mL) and 94.2% had insufficient vitamin D (<30 ng/mL). During a median follow-up of 9.4 years (interquartile range, 8.1-10.6 years), 1680 deaths were documented, including 362 CVD deaths and 570 cancer deaths. Serum 25(OH)D levels ≥30 ng/mL were inversely associated with all-cause mortality (HR, 0.57; 95% CI, 0.43-0.75) compared with serum 25(OH)D levels <10 ng/mL. Based on the quartile cutoffs of serum 25(OH)D concentration, the highest quartile of serum 25(OH)D concentration (≥21.8 ng/mL) was associated with the lowest all-cause mortality (HR, 0.72; 95% CI, 0.60-0.85; P trend < .001), and CVD mortality (HR, 0.60; 95% CI, 0.42-0.85; P trend = .006). No association with cancer mortality outcome was found. In conclusion, higher serum 25(OH)D levels were associated with lower all-cause mortality in the general Korean population. An additional association was found between higher quartile of serum 25(OH)D and lower CVD mortality.

Objective: We aimed to investigate the longitudinal trends in prevalence of hypertriglyceridemia in Korean adults and hypertriglyceridemia-associated lifestyle habits, socioeconomic factors and comorbidities. Methods: Data from the 2007-2020 Korea National Health and Nutrition Examination Survey (KNHANES) were used in this study. Two cutoff values (≥150 mg/dL and ≥200 mg/dL) for fasting serum triglyceride levels were used to estimate the age- and sex-specific prevalence of hypertriglyceridemia. Use of lipid-lowering medications, lifestyle factors such as smoking, alcohol consumption, and regular exercise, socioeconomic variables such as educational attainment and household income, and comorbidities such as obesity, abdominal obesity, hypertension, and diabetes mellitus were also investigated. Results: The prevalence of hypertriglyceridemia among Koreans based on KNHANES 2007-2020 was 29.6% at ≥150 mg/dL and 16.1% at ≥200 mg/dL. While the rate of using lipid-lowering medications increased steadily from 2007 to 2020, changes in annual prevalence of hypertriglyceridemia were subtle. The prevalence of hypertriglyceridemia in men peaked in middle age (47.7% and 30.0% for ≥150 mg/dL and ≥200 mg/dL, respectively, in their 40s), but its prevalence in women increased throughout their lifetime (32.6% and 14.7% for ≥150 mg/dL and ≥200 mg/dL, respectively, in their 70s). Smoking and high-risk drinking exacerbated peak prevalence in both sexes. Young adults with any comorbidities had prominently increased prevalence of hypertriglyceridemia. The lowest levels of education and income were both associated with the higher prevalence of hypertriglyceridemia in both sexes. Conclusion: It is important to understand the age- and sex-specific epidemiology of hypertriglyceridemia to establish its appropriate management plans.
RESUMEN
Previous studies have applied interview-oriented self-reported or peer-centered evaluation methods, rather than an objective and quantitative method, to evaluate outcome of a postgraduate capacity-building program and have mainly focused on the cognitive level. To investigate the feasibility of the objective structured clinical examination (OSCE) in an international setting and report the results of the outcome evaluation for the behavioral aspect. A case-control study. Ninety examinees divided into 2 case-control groups: 17 program-experienced doctors and 17 control doctors in the first group, and 28 mentees of the program-experienced doctors and 28 control doctors in the second group. A six-station OSCE was implemented. The OSCE scores were measured to evaluate (1) the direct educational effect regarding learning in the first group and (2) the indirect educational effects regarding transfer in the second group. Written questionnaire and interview data were collected for qualitative analysis. The quantitative results of the overall or subcomponent OSCE scores indicated no significant differences in the comparisons of the first and second case-control groups. The qualitative data indicated that the program improved participants' medical knowledge, skills, and self-confidence, however, it also revealed limited learning environment provided by the program. This transnational study has demonstrated the process for introducing and successfully completing the testing of an OSCE in Laos. Discrepancy in the goals of the OSCE and the education program limited the usefulness of OSCE as an assessment tool, leading to the lack of significant differences in its results.

OBJECTIVES: Studies evaluating weight changes during the coronavirus disease 2019 (COVID-19) pandemic have yielded inconsistent results, and most of those studies were based on self-reported anthropometric measures. We investigated changes in body mass index (BMI), professionally measured waist circumference (WC), and metabolic syndrome components from before to during the pandemic in a sample of the adult population in Korea. METHODS: This retrospective study included 1,118 male and female (age≥18 years) who underwent health checkups at a university medical center between January 1, 2016 and March 31, 2022. Changes in BMI, lifestyles, and metabolic syndrome components during the pandemic were analyzed using the paired t-test, McNemar test, generalized estimating equations, and repeated-measures analysis of variance. RESULTS: Changes in body weight, BMI, and body fat percentage during the pandemic were not clinically significant. However, statistically significant results were found for decreased physical activity (p<0.001) and WC (p<0.001), and exacerbation of all metabolic syndrome components (except serum triglyceride levels). Moreover, the metabolic syndrome prevalence increased significantly from 20.2% to 31.2% during the pandemic (p<0.001). The prevalence of abdominal obesity and high fasting blood glucose levels also significantly increased from 2019 to 2021. CONCLUSIONS: Metabolic syndrome, its components, and fat distribution worsened significantly after the implementation of social distancing and lockdowns, despite no clinically significant changes in body weight and BMI. Further studies on the post- pandemic period should investigate the long-term impact of social lockdowns on BMI and the prevalence of metabolic syndrome.

OBJECTIVE: To examine the association between changes in fatty liver disease (FLD) over time and the risk of type 2 diabetes in elderly individuals with prediabetes. METHODS: A total of 156,984 elderly individuals with prediabetes who underwent national health screening in 2009 and 2011 were followed up through December 31, 2019. The FLD status was defined as a change in the fatty liver index. Prediabetes was defined as impaired fasting glucose levels at baseline. Multivariable Cox proportional hazards regression was used to calculate the hazard ratio and CIs for type 2 diabetes according to the changes in FLD. RESULTS: During a median of 8.35 years of follow-up, type 2 diabetes developed in 29,422 (18.7%) elderly individuals with prediabetes. Multivariable adjusted hazard ratio of type 2 diabetes according to FLD change was 2.22 (95% CI, 2.11 to 2.34) in individuals with persistent FLD compared with those who have never had FLD. Although overall weight loss of 5% or more was associated with a 7% lower risk of type 2 diabetes in total participants, fatty liver status was important. Even with weight loss, those with a history of fatty liver-resolved FLD, new FLD, or persistent FLD-had an increased risk of type 2 diabetes. The risk of type 2 diabetes did not increase in individuals with sustained FLD-free status, regardless of weight change. CONCLUSION: The presence and change of FLD are important factors for the development of type 2 diabetes in elderly individuals with prediabetes.

BACKGROUND: Empathy is the core of the physician-patient relationship. The Consultation and Relational Empathy (CARE) measure is a useful tool for assessing patient-rated empathy. There have been scarce data on empathy in chronic disease patients in Korea. We aim to evaluate empathy using the Korean CARE measure in patients from various clinical environments and the factors influencing the degree of empathy in patients with chronic disease. METHODS: Data were collected from patients with chronic diseases. Patients were from primary, secondary, and tertiary clinics. Characteristics of the patients, physicians, and disease status were collected. The difference in CARE score was studied according to the clinical factors. RESULTS: A total of 162 patients with chronic diseases were included. About 60% of patients were male. The mean age was 62 years. They had an average number of 2.6 diseases. More than half of patients experienced overt cardiovascular disease. About half of them had a history of hospitalization due to cardiovascular disease. The overall average CARE score was 45.6 ± 7.0. The CARE score was not significantly different according to the characteristics of the patient, physician, or disease status. Regarding marital status, the CARE score was significantly lower for the small number of patients (n = 4, 2.5%) who refused to provide their marital status than for other groups. Except for four patients, there was no significant difference in the CARE score among married, unmarried, or divorced groups. This trend was maintained in hypertensive patients. CONCLUSIONS: The Korean CARE measure could assess patient-rated empathy in various clinical practices. The empathy of patients was high regardless of multiple factors.
RESUMEN
BACKGROUND: Although numerous studies have indicated that lower levels of physical activity correlate with a higher risk of depression, an association between the type of physical activity and depression has not been identified in Korea. This study aimed to examine whether the type and intensity of physical activity are associated with depression in Korean adults. METHODS: This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 11,679 individuals were analyzed using multiple logistic regression analyses to identify any association between the type of physical activity and depressive disorders in the sample subjects. RESULTS: Measured weekly in units of energy expenditure, known as metabolic equivalents (METs), the amount of work-related physical activity was higher in individuals with depression according to the Patient Health Questionnaire- 9 than the participants without depression (386.7 vs. 206.7 MET-min/wk, P=0.01). Those diagnosed with depression tended to engage in less recreational activity per week (143.7 vs. 316.3 MET-min/wk, P<0.001) than those without depression. After controlling for covariates, the risk of depression among all participants was 1.012 times higher with a 100-unit increase in total work-related activity measured in METs (95% confidence interval [CI], 1.006-1.017; P<0.001) and 0.962 times lower with a 100-unit increase in total leisure activity measured in METs (95% CI, 0.937-0.987; P=0.003). CONCLUSION: Different types of physical activity were shown to be differently associated with depressive disorders in Korean adults. This study might guide in reducing work-related physical activity and increasing leisure activity to prevent the occurrence of depression.
