BACKGROUND/OBJECTIVES: The objective of this study was to compare dietary habits and mental health among middle school students in urban and rural areas based on bedtime, and to provide evidence supporting appropriate bedtime for Korean middle school students in relation to their healthy dietary habits and mental well-being. SUBJECTS/METHODS: The study population consisted of 25,681 second-year middle school students who participated in the Korea Youth Risk Behavior Survey in 2020-2022. Participants were asked about their bedtime and wake-up time during the past 7 days and were classified into five categories. The study compared the general characteristics, academic factors, dietary habits, and mental health of urban and rural students based on their bedtime. RESULTS: Bedtime was found to be later in the following order: urban female students, rural female students, urban male students, and rural male students. As bedtime got later, the rates of smoking and alcohol consumption increased. Students who went to bed before 11 p.m. had lower academic performance, while rural male students who went to bed after 2 a.m. had lower academic performance. Later bedtime was associated with increased smartphone usage, skipping breakfast, consuming fast food, and drinking carbonated beverages. Later bedtime was also associated with higher perceived stress levels, particularly among students who went to bed after 2 a.m., higher rates of suicidal ideation, experiencing sadness and despair, as well as the prevalence of clinically significant anxiety disorders. CONCLUSION: These results suggest that middle school students who go to bed too late have higher rates of smoking and alcohol drinking, as well as unhealthy eating habits, stress, suicidal ideation, sadness, and anxiety. Therefore, it is necessary to provide educational and social institutional support to promote adequate sleep for the health of adolescents.

The study was carried out to estimate the prevalence and possible causes of refractive errors in primary school children. At one primary school in urban Daegu, one in the medium-sized city of Yongcheon and 2 in rural areas, children wearing glasses and children with visual acuity of less than 0.7 were given our questions. 354 out of 378 children responded to our questions. The research was done from March 2000 to February 2001. The data were analyzed by percentage, x2 test, t-test, ANOVA and Scheff method. Children with eyesight problems were more prevalent in urban areas than rural areas. The lack of luminosity during reading (p=0.015), length of reading time (p=0.08) and posture which watching TV (p=0.023) appeared leading causes of progressing myopias. The visual impairment caused by refractive errors may affect the mental and physical activity of primary school children and lead to social isolation, loneliness and depression. However, little attention may be paid by professionals engaged in providing health care to the children. Once we have recognized the impact of visual impairment, we may be in a better position to prevent progressing refractive errors.

Objectives: The purpose was to test the effect of an empowerment health management program on self-esteem and the quality of life for the elderly who live in cities. Methods: Forty-three elders were randomly assigned to either the experimental group that received the intervention to participate in one year's empowerment practice (one home visiting per week and phone counselling) (n=21) or to the control group that got home visiting only (n=22). The data was analyzed using ANCOVA. Results: There was no significant difference in the self-esteem score between the two groups after the intervention. But the quality of life score of the experimental group was significantly different from that of the control group after the intervention. Conclusions: The health management intervention using empowerment for the elderly living alone with chronic diseases in urban areas had positive effects on the quality of life. Therefore this intervention can be broadly applied to other elders living alone with chronic diseases in urban areas.

This study was conducted to measure the diurnal variation and behaviour of atmospheric mercury in an urban area by gold amalgamation and cold vapour atomic absorption spectrophotometry. The results were as follows: 1. The Hg concentration in ambient air averaged. 21.13ng/m$^3$ for 111 determinations (C.V. 78.5) in urban area and 5.91ng/m$^3$ for 140 determinations (C.V. 21.3) in suburban area. The urban area concentration was significantly higher and fluctuated more than its rural counterpart. 2. Regression analysis of the interaction between mercury concentration and other components showed a significant correlation between mercury concentration and sulfur dioxide also, TSP were found. Mercury concentration was shown to have a similar behaviour, on the whole, with other air pollutants. 3. It demonstrated a positive correlation with sunlight (UV-ray), while it had a negative response to wind speed and humidity. Its concentration showed a tendensy to increase during calm weather specifically. 4. The Hg concentration at the Mt. Dok You inland clean area ranged from 1.33ng/m$^3$ to 2.0ng/m$^3$, with a mean value of 1.63ng/m$^3$.

Iron deficiency and anemia are severe nutrition problems in most of Korea. Iron intake, especially iron with better bioavailability is insufficient over a total age group. Recent changes in diet and life style of Koreans have been repeatedly suggested problems caused by excess nutrient intake rather than under intake. Despite the changes in diet patterns, iron deficient anemia is still prevalent in many parts of Korea. Eight hundred and fifty subjects (323 male and 527 female subjects) in Asan were recruited from farming, factory and urban area. Each subject was interviewed to assess nutrients intakes according to a 24hr-recall method. Twelve hour fasting blood samples were collected to vacutainer with EDTA for hemoglobin (Hb) and separate the tubes for serum iron (SI) and total iron binding capacity (TIBC). The mean serum iron value of female subjects in the factory area was significantly higher (p < 0.05) than that of the female subjects in the urban area although subjects in urban area showed significantly higher the dietary iron intake for both the men and woman (p < 0.05). Dietary iron intake for the younger women was lowest in the farming area and those in the urban area showed the highest dietary iron intake (p < 0.05). When the dietary iron intake was compared by different the age groups, dietary iron intake of the older women from animal sources was less than that of younger women in the urban area (p < 0.05). Dietary iron intake of Asan residents was not sufficient regardless of age, sex and regions and intake of heme iron was especially lower than nonheme iron. (J Community Nutrition 5(1) : 37∼43, 2003)

Objectives： To examine the regional mortality differences in The Republic of Korea according to geographic location. Methods： All 232 administrative districts of the Republic of Korea in 1998 were studied according to their geographic locations by dividing each district into three categories； "metropolis," "urban," and "rural". Crude mortality rates for doth sexes from total deaths as well as the three major causes of death in Korea (cardiovascular disease, cancer, and external causes) were calculated with raw data from the "1998 report on the causes of death statistics" and resident registration data. Standardized mortality ratios (SMR) were calculated using the indirect standardization method. Poisson regression analyses were performed to examine the effects of geographic locations on the risk of death. To correct for the socioeconomic differences of each region, the percentage of old ($\geq$ 65 years old) population, the number of privately owned cars per 100 population, and per capita manufacturing production industries were included in the model. Results： Most SMRs were the lowest in the metropolis and the highest in the rural areas. These differences were more prominent in men and in deaths from external causes. In deaths from cancer in women, the rural region showed the lowest SMR. In Poisson regression analysis after correcting for regional socioeconomic differences, the risk of death from all causes significantly increased in both urban (OR＝1.111) and rural (OR＝1.100) regions, except for rural women, compared to the metropolis region. In men, the rural region showed higher risk (OR＝1.180) than the urban region (OR＝1.l51). For cardiovascular disease and cancer, significant differences were not found between geographic locations, except in urban women for cardiovascular disease (OR＝1.151) and in rural women for cancer (OR＝0.887), compared to metropolis women. In deaths from external causes, the risk ratios significantly increased in both urban and rural regions and an increasing tendency from the metropolis to the rural region was clearly observed in both sexes. Conclusions： Regional mortality differences according to geographic location exist in The Republic of Korea and further research and policy approaches to reduce these differences are needed. to reduce these differences are needed.

Objectives: Women experience more stress in middle age than in other periods of their lives. Therefore, health management programs that enable middle-aged women to cope with and manage stress are needed. This study investigated the psychological effects of a meditation-focused forest therapy program among 53 middle-aged women living in urban areas in Korea. Methods: Participants were divided into 2 groups: one group underwent the program for 3 days in a forest, followed by 3 days in an urban environment, and the other group underwent the program for 3 days in the urban environment, followed by 3 days in the forest. The psychological effects of the forest therapy program were evaluated using the Profile of Mood States-Brief (POMS-B). Differences in mood state before and after the program conducted in the forest (experimental group) and in the urban environment (control group) were evaluated using the paired-samples t-test. Results: The program in the forest significantly reduced tension, depression, anger, fatigue, and confusion among the domains of the POMS-B. The program in the urban area significantly reduced tension, but not depression, anger, fatigue, or confusion. Conclusions: Meditation-focused forest therapy programs are expected to contribute to promoting psychological health and enhancing the quality of life of middle-aged women.
