Validating the Autism Diagnostic Interview-Revised in the Korean Population

Objective@#This study aimed to examine the validity of the Korean version of the Autism Diagnostic Interview-Revised (K-ADI-R) and determine its efficacy in identifying individuals with autism spectrum disorder (ASD). @*Methods@#Data were pooled from several past and ongoing studies as well as clinical records acquired at Seoul National University Bundang Hospital from 2008 to 2017. The K-ADI-R were administered and scored by trained research reliable examiners. Measurements to investigate the validity of the K-ADI-R was through sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and Cohen’s kappa. @*Results@#A total of 1,271 (age 88.9±62.42 months, male=927) participants were included. The K-ADI-R yielded strong psychometric properties with high sensitivity (86.06–99.27%), specificity (84.75–99.55%), PPV (92.33–99.72%), and NPV (79.43–98.64%). There were significant differences in item scores across the K-ADI-R diagnostic algorithm regardless of age and sex (p<0.001). Agreement between the K-ADI-R and other ASD related measurements ranged between levels of good to excellent. @*Conclusion@#Despite language or cultural boundaries, the K-ADI-R demonstrated high levels of sensitivity, specificity, PPV, and NPV within a wide range of participants; hence, suggesting promising usage as a valuable diagnostic instrument for individuals with ASD.

Variations and Factors Associated with the Supply and Utilization of Nursing Home Services in Japan and South Korea / 보건행정학회지

Background@#Few studies have examined the performance of the public long-term care insurance (LTCI) from the perspective of geographic equity. This study investigated regional variations and associated factors in the supply and utilization of nursing home care within and also between Japan and Korea. @*Methods@#A comparative dataset was developed by extracting data from 2013–2015 LTCI statistics yearbooks and Organization for Economic Cooperation and Development regional statistics, as well as other comparable data in Japan and Korea. The unit of analysis was the prefecture in Japan and the province in Korea. We computed variation indices and conducted regression analyses for regional variations within each country and decomposition analyses to examine the variations between the countries. @*Results@#The overall regional supply and use of nursing home care were higher in Japan, but the regional variations in Korea were larger than in Japan. In both countries, the nursing home supply was negatively associated with the proportion of older people with independent living. Nursing home use was also negatively associated with the supply of hospital beds and home care agencies in Korea; the relationship was the opposite in Japan, however. The country-based differences were more likely to be explained by differences in the distributions of the variables included in the analytical model than country-specific characteristics. @*Conclusion@#Regional-level nursing home supply and use were unequal in both countries, and the contributing factors were not the same. Policy efforts are needed to advance regional equality in long-term care (LTC) and collaboration between health and LTC institutions for frail older people, especially in Korea.

Differences in Personality, Defense Styles, and Coping Strategies in Individuals with Depressive Disorder According to Age Groups Across the Lifespan

OBJECTIVE: This study aimed to examine the differences in personality, defense style, and coping styles among patients with depression according to age groups.METHODS: A total of 211 participants ranging from 19 to 81 years old were recruited for the study. To assess participants’ five dimensions of personality, the Neuroticism-Extraversion-Openness Personality Inventory-Revised (NEO-PI-R) was administered. In addition, the Korean-Defense Style Questionnaire and the Korean version of the coping checklist were administered to examine the defense and coping style.RESULTS: In the analysis of NEO-PI-R, the mean value of Agreeableness, Conscientiousness, and Neuroticism showed significant differences between the young adult age group (20–34 years) and the late middle age group (50–64 years) (p<0.05). The young age group used more immature defense styles and made less use of problem-focused coping strategy than the old age patients (65 years and older) (p<0.05).CONCLUSION: In the young age group associations with lower Agreeableness and Conscientiousness, as well as higher Neuroticism than the late middle age group were observed. Moreover, the young age group had a higher usage of immature defense style, and restricted use of problem-focused coping style than other age groups.

Long-Term Care Utilization among End-of-Life Older Adults in Korea: Characteristics and Associated Factors / 보건행정학회지

BACKGROUND: The purpose of this study is to examine the characteristics of and factors associated with long-term care (LTC) utilization under public long-term care insurance (LTCI) among end-of-life older adults in Korea. METHODS: Using a 5% sample of older people aged 65 or older and their health and LTC insurance data, two-part model analyses were conducted. We compared LTC uses and their determinants during the last year of life among decedents in the year 2010 with those of survivors. We also compared the medical uses of the same sample with their LTC uses. RESULTS: The end-of-life elderly were more likely to use LTC, and their expenditure on LTC was higher than their counterparts. Whether or not older people used LTC during their last year of life was significantly affected by age, sex, health insurance, household income, and living alone; however, LTC costs of the decedents were only affected by functional status, which may have been due to the reimbursement scheme of the current LTCI, which is mainly based on functional dependency level. For the survivors, having chronic diseases significantly increased the likelihood of LTC use, which was not the case for the decedents. End-of-life elderly with relatively low social economic status were more likely to use the LTC other than medical services, while the health conditions affected their medical uses most significantly. CONCLUSION: The study findings provide key information for predicting demand related to the increasing LTC needs of Korean older people at the end of life.

Routine Screening and Consultation Facilitate Improvement of Metabolic Syndrome

This randomized controlled trial study aimed to investigate the effects of a lifestyle intervention on metabolic syndrome (MetS) among middle-aged Koreans. A total of 243 middle-aged Koreans with MetS were randomly assigned to either of 2 types of lifestyle intervention for MetS and followed for 12 months. Health examinations and interventions were implemented at 16 regional branch facilities of a Korean medical institution from 2010, following the NCEP-ATP III criteria and recommendations. Lifestyle intervention (LI) group (n = 137) participated in a 12-week multi-component intervention including individual counseling, group sessions, and self-help materials. Basic usual intervention (BI) group (n = 106) was provided with one-page health information sheet on MetS and MetS management at baseline. Prevalence of MetS and each of MetS components, except for low HDL-cholesterol, in both groups were significantly reduced and maintained after the intervention. Notably, prevalence of hypertension and abdominal obesity continued to improve during the follow-up period. Between-group differences in results were not found. Both interventions were effective when they were accompanied with repeated check-ups and notification of MetS status. It is recommended to design clear guidelines for the notification of MetS after MetS screening and to encourage checking MetS status periodically for effective MetS management (KCT 0000446).

The effects of community environmental factors on obesity among Korean adults: a multilevel analysis / 한국역학회지

OBJECTIVES: This study explored multidimensional factors related to obesity by dividing them into individual and environmental factors, and performed multilevel analysis to investigate community environmental effects. METHODS: Data from the 2011 and 2012 Community Health Surveys were used for the analysis. Community-level variables, constructed from various regional statistics, were included in the model as environmental factors. Respondents with body mass index (BMI)> or =25 were defined as obese, and a multilevel logistic regression analysis was conducted to analyze individual and environmental factors related to obesity. Moreover, a stratified analysis was conducted to compare factors related to obesity between men and women. RESULTS: Of 337,136 samples, 82,887 (24.6%) were obese, with BMI> or =25. Sociodemographic characteristics at the individual level were mostly significantly related to obesity; however, while there were more obese men subjects among those with high socioeconomic status, there were more obese women among those with low socioeconomic status. There were fewer obese respondents among those who regularly walked and more obese respondents among those who reported short sleep duration or were highly stressed. At the community level, people living in areas with high socioeconomic status, high satisfaction with safety and public transportation, and high accessibility to sports facilities in their community had lower obesity risks. CONCLUSIONS: Community-level environmental factors affected obesity, especially perceived community environment, more significant than physical environment. Thus, it is necessary to develop effective obesity prevention and management strategies by considering potential community environmental factors that affect obesity.
