The Effects of Injury on Depression and Mental Health of South Korean Adults

Background/Objectives: This study aimed to determine the effects of injury experience on depression and mental health of adults. Methods/Statistical analysis: This study used the raw data from Korea Health Statistics 2014: Korea National Health and Nutrition Examination Survey (KNHANES VI-2). The respondents aged <20 years and those giving no response were excluded from this study. The subjects were screened in two phases. Congruity in individual ID, household ID, research district, gender, age, household income, education level, and occupation was examined in the process of screening and 4,755 persons were finally selected. Of the 4,755 persons, only 358 were reviewed for injury and depression diagnosis status. An SPSS Version 18.0 WIN program was used to analyze the data. Findings: The more household income (approx. 1.5 times; p<.01) and the higher education level (approx. 1.5 times; p<.01), the higher level of one-year experience of injury. As for occupation, technical service affected one-year experience of injury (p<.01). As for injury type, laceration/stab/amputation affected depression diagnosis status. As for injury intention, an accident was more likely to affect depression diagnosis status than intentional self-injury and violence. As for injury intention, intentional self-injury and violence (1.84 points) more adversely affected mental health than accidents (1.39) (p<.05). Improvements: Injury experience affected depression diagnosis status and mental health. In solving this problem, it is necessary to reinforce both mental health education programs and treatment and management programs.

Estimation of Apple Intake for the Exposure Assessment of Residual Chemicals Using Korea National Health and Nutrition Examination Survey Database.

The aims of this study were to develop strategies and algorithms of calculating food commodity intake suitable for exposure assessment of residual chemicals by using the food intake database of Korea National Health and Nutrition Examination Survey (KNHANES). In this study, apples and their processed food products were chosen as a model food for accurate calculation of food commodity intakes uthrough the recently developed Korea food commodity intake calculation (KFCIC) software. The average daily intakes of total apples in Korea Health Statistics were 29.60 g in 2008, 32.40 g in 2009, 34.30 g in 2010, 28.10 g in 2011, and 24.60 g in 2012. The average daily intakes of apples by KFCIC software was 2.65 g higher than that by Korea Health Statistics. The food intake data in Korea Health Statistics might have less reflected the intake of apples from mixed and processed foods than KFCIC software has. These results can affect outcome of risk assessment for residual chemicals in foods. Therefore, the accurate estimation of the average daily intake of food commodities is very important, and more data for food intakes and recipes have to be applied to improve the quality of data. Nevertheless, this study can contribute to the predictive estimation of exposure to possible residual chemicals and subsequent analysis for their potential risks.

국내 시중 유통 수산물에 대한 방사능 농도 조사

Samples of fishery products were tested for radioactivity by using the intake frequency data from Korea Health Statistics. The radioactivity of 40 K, 137 Cs, 134 Cs, and 131 I was analyzed using gamma spectrometry with a simplified sample pre-treatment procedure. The radioactivity range for 40 K was 21.9-3050 Bq/kg, whereas the radioactivities of 137 Cs, 134 Cs, and 131I were under minimum detectable activity which were in the range of 0.140-1.97, 0.0900-1.89 and 0.124-1.94 Bq/kg, respectively, for the three species. The results suggest that the Fukushima accident did not have a significant impact on domestic fishery products, which were analyzed during the period from 2013 to 2015. Additionally, there seemed to be no significant impact of additional exposure dose by the analyzed radionuclides.

자연산 및 양식산 메기의 미네랄 함량 및 영양평가

This study was performed to evaluate mineral contents of catfish Silurus asotus. As a result of mineral content, the mean content of the macro mineral was (in descending order): K (310.36-412.66 mg/100 g), P (186.42-223.02 mg/100 g), Na (35.32-57.87 mg/100 g), Mg (22.88-31.87 mg/100 g), Ca (9.05-13.07 mg/100 g). In comparison, the mean content of the micro mineral was (in descending order): Fe (0.26-0.95 mg/100 g), Zn (0.26-1.02 mg/100 g), Cu (ND-0.08 mg/100 g), Mn (0.01-0.03 mg/100 g). A proportion of mineral intakes with the dietary reference intakes for Koreans (KDRIs) set by the Korean Nutrition Society. Nutrient uptake proportion of mineral intakes was (in descending order): P (62.16%), K (20.71%), Mg (16.82%), Fe (13.02%), Zn (11.38%) Cu (10.94%), Na (6.59%), Ca (3.09%), Mn (0.96%). The mineral content was compared with the major protein food sources according to the Korea Health Statistics (2013) such as polished rice, pork, chicken, beef, eggs and milk. The calcium content contains; lower level of milk and eggs, chicken whereas higher levels of rice, pork and beef. Catfish has less iron content than major protein food source. Phosphorus and potassium contain higher level of major protein food sources.

The Relationship between AUDIT Scores and Mental Health Counseling among Korean Adults 20 Years Old or Over

This study tries to examine the relationship between AUDIT scores and mental problem counseling among Korean adults 20 years old or over. The source of this research is the raw data contained in the Korea Health Statistics 2012: Korea National Health and Nutrition Examination Survey, KNHANES v-3 published by the Ministry of Health and Welfare and the Korea Center for Disease Control and Prevention (CDC). From the raw data, the respondents who were below 20 years old, and did not answer any of the ten AUDIT questions were excluded, and, finally, 4681 respondents were used for analysis. The data was analyzed with the SPSS Version 12.0 WIN program. The analysis found that those who belong to the problematic drinking group seek mental problem counseling 2.4 times as often as those who belong to the normal drinking group (p<.01), and that those who belong to the alcoholic abuse and dependence group did it 2.8 times as often as those who belong to the normal drinking group (p<.05). The analysis found that the problematic drinking group and the alcohol abuse and dependence group were related with mental problem counseling. To solve the problem, it seems necessary to establish an institution designed to build sound drinking culture and reduce mental problems.

The Relevance with Mental Health in the Activity Limitation and the Quality of Life in Korean Adults

The purpose of this study is to examine the relevance with mental health in the activity limitation and the quality of life in our country's adults. This study was based on the source data of “Korea Health Statistics 2012: Korea National Health and Nutrition Examination Survey [KNHANES V-3]” by Ministry of Health and Welfare (MW) and Korea Centers for Disease Control and Prevention (CDC). The subjects were composed of 5515 people excluding those aged under 20, missing values, and non-respondents from the primitive data. An analytical method of this study was made by using SPSS WIN 12.0 Version. As for the quality of life, the group having some problems with walking in terms of motor ability was about 1.4 times more likely to have depressive symptoms (p<.05). The group having problems with daily activity was about 2.4 times more likely to have depressive symptoms (p<.05). The group having moderate levels of psychological anxiety/depression (approx. 5 times, p<.001) and the group having severe psychological anxiety/depression (approx. 14 times, p<.001) were more likely to be depressed. In terms of the quality of life, activity limitation may cause a problem with daily living and mental health. It is necessary to develop programs and systems to solve this problem.

Data Resource Profile: The Korea National Health and Nutrition Examination Survey (KNHANES)

The Korea National Health and Nutrition Examination Survey (KNHANES) is a national surveillance system that has been assessing the health and nutritional status of Koreans since 1998. Based on the National Health Promotion Act, the surveys have been conducted by the Korea Centers for Disease Control and Prevention (KCDC). This nationally representative cross-sectional survey includes approximately 10 000 individuals each year as a survey sample and collects information on socioeconomic status, health-related behaviours, quality of life, healthcare utilization, anthropometric measures, biochemical and clinical profiles for non-communicable diseases and dietary intakes with three component surveys: health interview, health examination and nutrition survey. The health interview and health examination are conducted by trained staff members, including physicians, medical technicians and health interviewers, at a mobile examination centre, and dieticians’ visits to the homes of the study participants are followed up. KNHANES provides statistics for health-related policies in Korea, which also serve as the research infrastructure for studies on risk factors and diseases by supporting over 500 publications. KCDC has also supported researchers in Korea by providing annual workshops for data users. KCDC has published the Korea Health Statistics each year, and microdata are publicly available through the KNHANES website (http://knhanes.cdc.go.kr).
