The present study aims to examine the effect of depressive symptoms on suicidal ideation and the mediated moderating effect of social relations through social trust among Korean older adults. Drawn for the 13th wave of the Korea Welfare Panel Study, our sample consists of a total of 3,436 older adults aged 60 and over. Results from binary logistic regression analysis were as follows: First, older adults who reported higher levels of depressive symptoms were more likely to have suicidal ideation and social relations moderated the relationship between depressive symptoms and suicidal ideation. Second, older adults who reported higher levels of depressive symptoms were more likely to have poor social trust. Third, the moderating effect of social relations was mediated by social trust in the relationship between depressive symptoms and suicidal ideation. Findings suggest that it is necessary to build national- and community-level suicide prevention infrastructure for older adults by extending social capitals. 본 연구는 노년기 우울감과 자살생각 간의 관계에서 사회적 신뢰를 통한 사회관계 만족도의 매개된 조절효과를 검증한 연구이다. 연구방법은 제13차 한국복지패널 자료를 활용하여, 60세 이상 3,436명의 데이터를 이항 로지스틱 회귀분석을 적용하여 분석하였다. 단계적 접근법을 통해 매개된 조절효과를 검증한 결과는 다음과 같다. 첫째, 우울감이 높은 노인일수록 자살생각을 할 가능성이 높았다. 이러한 노년기 우울감과 자살생각 간의 관계는 사회관계 만족도의 수준에 따라 달라지는 것으로 나타났다. 둘째, 우울감이 높은 노인은 사회적 신뢰 정도가 낮은 것으로 나타났다. 이때, 우울감과 사회적 신뢰의 관계는 사회관계 만족도의 수준에 따라 다르게 나타났으며, 사회관계에 대해 만족하는 노인일수록 사회적 신뢰의 수준이 긍정적인 것으로 나타났다. 셋째, 우울감이 자살생각에 영향을 미칠때, 사회관계 만족도가 높은 노인의 경우 사회적 신뢰가 증가하여 자살생각이 유의하게 감소하는 것으로 나타났다. 이는 우울감이 자살생각에 미치는 영향에서 사회관계 만족도의 효과는 사회관계 만족도와 함께 증가한 사회적 신뢰의 효과인 것을 의미하며, 최종적으로 사회적 신뢰를 통한 사회관계 만족도의 부분 매개된 조절효과가 확인되었다. 본 연구의 결과는 노년기 우울감과 자살생각 간의 관계에서 사회참여의 차별적 결과의 요인이 사회적 신뢰를 통한 효과임을 증명하였다. 이러한 결과를 바탕으로 사회자본 확충의 필요성을 강조하며, 노인 자살예방 인프라를 구축할 필요가 있음을 시사하고 있다.

본 연구는 한국 노인이 주관적으로 인식하는 감각장애와 인지기능 간의 관계 조사이다. 연구방법은 2017년 노인실태조사 자료를 활용하여 65세 이상 10,082명에 대한 주관적 감각장애에 대한 평가 자료와 MMSE-DS를 통한 인지기능 간 관계를 위계적 다중회귀분석과 로지스틱 회귀분석을 실시하였다. 연구결과 시력, 청력, 구강 기능에 대해 주관적 불편감을 보고할수록 인지기능 감소의 위험이 높게 나타났다. 또한 청력, 구강에 대한 불편감은 치매로 이어질 가능성이 높음을 발견하였다. 특히 다른 감각기능에 비해 청력 불편감이 치매의심 집단의 인지기능과 상관관계가 가장 높은 것으로 나타났다. 본 연구의 결과는 노인의 감각기능을 정부 차원에서 관리할 필요성이 있으며, 노인 스스로 감각기능의 신체적 변화를 지각하고 평가하기 위한 도구를 개발할 필요가 있음을 제안한다. 아울러 노인의 건강 증진을 위한 구체적인 방안을 위한 연구가 필요하다. The present study aims to examine the relationship between self-reported sensory impairment and cognitive function among older adults in Korea. Drawn from the 2017 Survey of Living Conditions and Welfare Needs Korean Older Persons, a total of 10,082 adults aged 65 and over were included in analyses. Results from hierarchial multiple regression analysis show that those who reported greater subjective discomfort about vision, hearing, and oral function were more likely to have poor cognitive function. Results from hierarchial logistic regression analysis show. Results from logistic regression analysis show that having hearing and oral discomfort increased the a risk for dementia. Findings suggest that it is necessary to manage sensory function of the elderly at the government level and to develop self-evaluation tools to monitor changes in sensory function for older adults. Future research should target finding effective ways to improve health of older adults.

Suhyun Hwang,Subin Bae,Shintae Kim,Jeongjin Park,Yoo-Hyun Lee,Woojin Jun 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

Non-alcholic fatty liver disease (NAFLD) is a disorder characterized by excessive accumulation of lipids in the liver without alcohol consumption. It is considered to be exacerbated from simple steatosis to fibrosis by many factors including oxidative stress, lipotoxicity, and insulin resistance. Phlomis umbrosa TURCZ. (PU) was proved their biological activities such as antioxidant, anti-inflammatory, anti-viral, and anti-osteoporosis. However, the mechanism and effect on hepatic steatosis has not been elucidated. The aim of this study is that investigated the potential of water extracts of PU (PUW) to modulate lipid accumulation and oxidative stress in NAFLD. The antioxidant activities of the PUW was measured by total phenolic compounds, flavonoid contents, DPPH, and ABTS radical scavenging activities. As a result of examining the degree of lipid accumulation in HepG2 cells induced by free fatty acids through AdipoRed, the PUW treatment group showed a significant decrease. It is thought that PUW may improve NAFLD by increasing antioxidant activity and reducing lipid accumulation.

이경식,Suhyun Bae,이승화,이정운,이동률 대한의학회 2014 Journal of Korean medical science Vol.29 No.11

This cross-sectional study was performed to investigate the reference values for bonemineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA) and theprevalence of osteoporosis in the Korean population by applying domestic reference data. In total, 25,043 Korean adults ≥ 20 yr of age (11,792 men and 13,251 women)participated in the study. The BMDs of the total hip, femoral neck, and lumbar spine weremeasured by DXA (Discovery-W, Hologic Inc.), and subjects with a BMD - 2.5 standarddeviations or lower than the mean BMD for young adults (20-29 yr old) were considered tohave osteoporosis. When applying the new reference values determined in this study fromKorean subjects, the overall prevalence of osteoporosis increased in men aged ≥ 50 yrcompared with that provided by the DXA manufacturer from Japanese subjects (12.2% vs. 7.8%, P < 0.001) and decreased in postmenopausal women aged ≥ 50 yr (32.9% vs. 38.7%, P < 0.001). According to the findings of this study, use of the reference valuesprovided by the DXA manufacturer has resulted in the underdiagnosis of osteoporosis inKorean men and the overdiagnosis of osteoporosis in Korean women. Our data will serve asvaluable reference standards for the diagnosis and management for osteoporosis in theKorean population.

Subin Bae,Shintae Kim,Suhyun Hwang,Jeongjin Park,Yongjae Kim,Yoo-Hyun Lee,Woojin Jun 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

Non-alcoholic fatty liver disease (NAFLD) is accompanied by an lipid accumulation and increase in oxidative stress caused by increase in reactive oxygen species (ROS). This study was designed to investigate alleviation effect of Salvia plevia R. Br. water extract (SPW) on NAFLD. HepG2 cells were pre-treated with 1 mM free fatty acids mixture (2:1 ratio of oleate : palmitate) for 24 h to induce lipid accumulation. As measured by Oil Red O and AdipoRed reagant, FFA groups increased intracellular lipid accumulation, whereas SPW groups significantly decreased. Also, the mRNA expression level of SREBP-1c was down-regulated in the SPW groups. On the other hand, the mRNA expression level of AMPK, PPARα, CPT-1 were up-regulated in the SPW groups. In addition, oxidative stress were increased by FFA, but treatment with SPW significantly decreased these levels. These results will provide that SPW ameliorate NAFLD by inhibition of lipid accumulation and reduction of oxidative stress.

Eunjoo Lee,Suhyun Bae,Meera Park 보안공학연구지원센터 2016 International Journal of Bio-Science and Bio-Techn Vol.8 No.3

In this study, the occurrence rate of postpartum depression of breastfeeding mothers and relation between postpartum depression and breastfeeding adaptation are to be investigated. Mothers with 5-7 month old infants who participated the Healthy Breastfed Baby Contest in Daegu Gyeongbuk, Korea and mothers who visited 1 women’s obstetrics hospital as outpatients were selected as research subjects in which a total of 110 subjects who agreed to participate the research were included. Data analysis was conducted using descriptive statistics, independent t-test, one-way ANOVA and Pearson’s correlation coefficients with SPSS v. 23.0 program. As result of the research, the occurrence risk of postpartum depression among breastfeeding mothers measured by EPDS (Edinburgh Postnatal Depression Scale) was shown to be 41.8% (cutting point 9/10) and significant negative correlation was shown between postpartum depression and breast feeding adaptation (r=-.38, p<.001). Also, postpartum depression was significantly higher when there were more children (F=3.33, p=.039) and exclusive breastfeeding showed to have significantly high breast feeding adaptation (t=3.45, p=.001). Therefore, breast feeding adaptation between the mother and child increases and continuous breast feeding can take place if the postpartum depression of breastfeeding mothers after birth is early discovered and managed.
