Background: The effects of physical activity on health vary depending on the individual’s age and the intensity and quality of physical activity. Hence, this study examined how the quality and intensity of physical activity are correlated with depression according to age. Methods: The current study used data from the 5th (2014-2015) to the 6th (2016-2017) Korea National Health and Nutrition Examination Survey. A total of 27,119 individuals over the age of 12 were selected. Variables such as adherence to aerobic physical activity guidelines and number of daily hours spent sitting, working (vigorous or moderate), at leisure (vigorous or moderate), moving (vigorous or moderate), practicing strength training, and walking were compared between groups with or without depression for two consecutive weeks by considering three age groups (adolescents, adults, and older adults). Results: Compliance with aerobic physical activity guidelines, vigorous work time in older adults and weekly walking in both adults and older adults were higher in the group without depression than in the group with depression. Meanwhile, the group with depression spent more time sitting than the adolescent group. Conclusion For adults aged 19 and older, meeting physical activity guidelines and walking regularly can help prevent mental illnesses such as depression. Adolescents can improve their mental health by reducing the amount of time they spend sitting. Further research is needed to confirm the relation between physical activity and depression prevention measures by utilizing advanced information communication technologies and physical activity measurement methods.

Background: Life stressors and habits that influence suicidal ideation (SI) differ across the life cycle. The study aims to analyze the different risk factors for SI among younger, middle-aged, and older adults. Methods: The current study used data from the 4th (2007-2009) to the 6th (2013-2015) Korea National Health and Nutrition Examination Survey (KNHANES). The researchers recruited a total of 49,487 adults over 19 years of age with no missing values in marital status, household income, area of residence, employment status, level of education, and regular walking. Results: The results identified depression, sex, alcohol problem, education, smoking, marital status, household income, and social care as risk factors for SI in the total sample. In younger adults, regular PA was included as a risk factor for SI, whereas social care was excluded from the risk factors. In middle-aged adults, educational attainment and social care were excluded from the risk factors for SI. In older adults, marital and job statuses were excluded from the risk factors for SI. Conclusion Several common risk factors for SI have been identified in adults over 19 years of age. According to their stage in the life cycle, there were several differences in the risk factors for SI.

OBJECTIVES: The objective of this study is to measure and to compare the rate of depression, anxiety, self-esteem and the quality of life of the patients with chest pain. Based on the result of this study, the necessity of the psychiatric assessment and treatment of the patients with chest pain is emphasized. This study is a preliminary research for a larger scale investigation to be carried out in the future. METHODS: Thirty nine patients with chest pain who visited Cardiovascular Division of Dept. of Internal Medicine Pusan National University Hospital and fourty normal control group(NC) were included in this study. The patients were classified into typical chest pain group(TCP, N=19) and atypical chest pain group(ACP, N=20) based on the cause of the pain. The cause was determined by cardiac computed tomography, exercise stress test, coronary angiography, and questionaires by a cardiology specialist. The patients were assessed with Beck Depression Inventory(BDI), State-Trait Anxiety Inventory(STAI), Rosenberg Self-Esteem Scale(RSES) and Korean version of the Smith Klein Beecham 'Quality of Life' scale(KvSBQOL). RESULTS: 1) When the risk factors of cardiac disease is compared, most of the factors(Hypertension, Diabetes, Hyperlipidemia, Cerebral infarction) did not differ significantly among the two chest pain groups, except for the family history, for which TCP group showed higher risk than ACP group did. 2) As for the self-report questionaires scores, BDI score, which indicates the rate of depression, of both ACP group and TCP group was significantly higher than that of NC group in BDI for depression. STAI score, which measures anxiety, was also significantly high in both groups. Especially, STAI score was significantly higher in ACP group than TCP group. 3) In the aspect of self-esteem and quality of life, ACP group scored significantly lower than TCP group and NC group. The scores for TCP group and NC group did not differ significantly. CONCLUSIONS: The patients with chest pain showed more depression and anxiety than normal control group, regardless of the cause of the pain. However, TCP group did not show significantly larger drop in self-esteem and quality of life than ACP group did. This result implies that early psychiatric assessment and treatment is needed for the patients with such chest pain, since it is highly likely that the pain would lead to lower quality of life of the patients.
