Purpose: The aim of this study was to assess lipid levels and to identify groups with poor lipid control group among patients with dyslipidemia. Methods: Data from 1,399 Korean patients with dyslipidemia older than 20 years were extracted from the Korea National Health and Nutrition Examination Survey. Complex sample analysis and decision-tree analysis were conducted with using SPSS for Windows version 27.0. Results: The mean levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein cholesterol were 211.38±1.15 mg/dL, 306.61±1.15 mg/dL, 118.48±1.08 mg/dL, and 42.39±1.15 mg/dL, respectively. About 61% of participants showed abnormal lipid control. Poor glycemic control groups (TC ≥ 200 mg/dL or TG ≥ 150 mg/dL or LDL-C ≥ 130 mg/dL) were identified through seven different pathways via decision-tree analysis. Poor lipid control groups were categorized based on patients' characteristics such as gender, age, education, dyslipidemia medication adherence, perception of dyslipidemia, diagnosis of myocardial infarction or angina, diabetes mellitus, perceived health status, relative hand grip strength, hemoglobin A1c, aerobic exercise per week, and walking days per week. Dyslipidemia medication adherence was the most significant predictor of poor lipid control. Conclusion: The findings demonstrated characteristics that are predictive of poor lipid control and can be used to detect poor lipid control in patients with dyslipidemia.

Objective: To evaluate circularity as a quantitative shape factor of small renal tumor on computed tomography (CT) in differentiating fat-poor angiomyolipoma (AML) from renal cell carcinoma (RCC). Materials and Methods: In 257 consecutive patients, 257 pathologically confirmed renal tumors (either AML or RCC less than 4 cm), which did not include visible fat on unenhanced CT, were retrospectively evaluated. A radiologist drew the tumor margin to measure the perimeter and area in all the contrast-enhanced axial CT images. In each image, a quantitative shape factor, circularity, was calculated using the following equation: 4 x π x (area ÷ perimeter²). The median circularity (circularity index) was adopted as a representative value in each tumor. The circularity index was compared between fat-poor AML and RCC, and the receiver operating characteristic (ROC) curve analysis was performed. Univariable and multivariable binary logistic regression analysis was performed to determine the independent predictor of fat-poor AML. Results: Of the 257 tumors, 26 were AMLs and 231 were RCCs (184 clear cell RCCs, 25 papillary RCCs, and 22 chromophobe RCCs). The mean circularity index of AML was significantly lower than that of RCC (0.86 ± 0.04 vs. 0.93 ± 0.02, p < 0.001). The mean circularity index was not different between the subtypes of RCCs (0.93 ± 0.02, 0.92 ± 0.02, and 0.92 ± 0.02 for clear cell, papillary, and chromophobe RCCs, respectively, p = 0.210). The area under the ROC curve of circularity index was 0.924 for differentiating fat-poor AML from RCC. The sensitivity and specificity were 88.5% and 90.9%, respectively (cut-off, 0.90). Lower circularity index (≤ 0.9) was an independent predictor (odds ratio, 41.0; p < 0.001) for predicting fat-poor AML on multivariable logistic regression analysis. Conclusion: Circularity is a useful quantitative shape factor of small renal tumor for differentiating fat-poor AML from RCC.

Purpose: To find out the differences in eating habits between poor feeding and non-poor feeding children. Methods: We performed questionnaires on 504 children under four years of age who visited hospitals in Gwangju city and JaollaNamdo from May to August, 2002. Results: 138 (27.4%) children were included in poor feeding group, and 366 (72.%) children were in non-poor feeding group. Breast feeding rate was 18.8% in the poor feeding group and 20.3% in the non-poor feeding group. Duration of breast feeding for less than six months were noted in 70.5% of poor feeding group, and 58.5% of non-poor feeding group. The time at starting solid food in the poor feeding group was as follows; 15.9% of infants started on solid food when they were 2~4 months old, 32.7% during 4~6 months, 38.1% during 6~8 months and 18.8% over one year of age. Solid food was given in wrongly manners in both groups by nursing bottles, including 80.4% in poor feeding group and 66.6% in non-poor feeding group. Conclusion: This study demonstrated close relationships among poor feeding children under four years of age with history of low rate and short duration of breast feeding, inappropriate time to start on solid food, less interest in food during mealtime, and unbalanced diet. Pediatricians should make an effort to play an important role in nutritional education and treatment in children.

This study attempted to empirically investigate the determinants of poverty transition of the working poor with disabilities from a dynamic perspective. Analyses were conducted on the data from Panel Survey of Employment for the Disabled(PSED, Year 1-6), included the households with a disabled head of household. The working poor were defined as the household of which income fell below 120% of the absolute poverty line among the households just described. As results, The 6-year mean poverty rate for the working poor with disabilities included in the analysis was 31.4%, approximately three times of the poverty rate of the total population and the working poor with disabilities were found to have greater difficulty with poverty exit once having fell into poverty than all households living in poverty. And it was found that the economic activity factor was the key determinant of in-work poverty. In addition, employment of the working poor with disabilities did not lead straight to poverty exit, and the quality, rather than the status of, employment was the key determinant of poverty exit. The implications of the findings of this study are that it is essential to increase decent jobs, expand the social safety net of the working poor with disabilities and establish poverty reduction measures for each class of the working poor with disabilities to exit from poverty.

This study aimed to analyze the relative effects of parents' child-rearing attitudes and the quality of peer and teacher relationships on poor adolescents' self-resilience and self-esteem. The subjects were 639 1st grade middle school students from the firstly poor, the secondary poor, and the thirdly poor families who participated in the Korea Child Youth Panel Surveys(KCYPS). The data were analyzed with descriptive statistics and hierarchical regressions. The results of this study were as follows. Firstly, the poor adolescents' self-resilience were influenced by the quality of peer relationships, parents' child-rearing attitudes, and the quality of teacher relationships in order and the specific variables enhancing adolescents' self-resilience were communication between adolescents and peers, trust with peers, parents' love, reasonable explanation, supervision, and teacher-adolescents' friendly relationships. Secondly, the poor adolescents' self-esteem were influenced by parents' child-rearing attitudes, the quality of peer relationships, and the quality of teacher relationships in order and the specific variables enhancing adolescents' self-esteem were parents' love, supervision, inconsistency, senses of non-alienation among peers, communication between adolescents and peers, trust with peers, and teacher-adolescents' friendly relationships. Finally, the future directions of education welfare programs targeting poor adolescents were suggested on the basis of the results.

The purpose of the present study was to examine the structural causal relationships among problem drinking of elderly, depression, self-esteem and life satisfaction through structural Equation Modeling and also to investigate how these effects were influenced by the differences in the structural relationships between poor and non-poor elderly. The results showed the positive relationship between problem drinking and depression not also poor elderly group but non-poor elderlys'. According to Multi-group analysis, Latent means analysis where non-poor elderly are used as the reference group, poor elderly group showed higher latent mean values on the problemdrinking and depression, and lower latent mean values on the self-esteem and life satisfaction. Depression mediated the relationships between problem drinking of elderly and life satisfaction the only in a poor elderly group. The implications and limitations of this study were discussed, and the suggestions for further studies were recommended.

Objectives: As the size of elderly population living alone grows, socioeconomic diversity has also increased. This study examined if social risk factors of poor self-rated health were distinguishable between the low income elderly and their non-low income counterparts both living alone. Methods: The '2006 Elderly Health Interview Survey' conducted by D-gu in Seoul was utilized. We divided the elderly living alone into two groups depending on their economic status: low income and non-low income. Employing logistic regression, we analyzed the associations of poor self-rated health with socio-demographic factors, health-related factors, social support, the relations with children, social activities, welfare service use, and the perception of neighborhood safety. Results: Proportion of rating one's own health being poor was different between two populations. Social support was important for the self-rated health of the non-low income elderly, while welfare service use, the perception of neighborhood safety, and the relations with children were noticeable for the low income elderly. Conclusions: To better understand the health need of elderly population living alone, their heterogeneity in socioeconomic characteristics should be taken into account.

Purpose: The purposes of this study were to (a) explore the prevalence of sleep patterns of middle-aged women; (b) identify the relationship between subjective sleep quality and its related variables; and (c) predict the possible explanations of how the related factors affect subjective sleep quality of middle-aged women. Methods: A total of 256 women aged 40-60 years were purposely sampled and given self-administered questionnaires in a cross-sectional, correlation coefficient design. The data was analysed using t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Results: The results were as follows; (a) a total of 40% of the women were poor sleepers as defined by a global PSQI score >5; (b) there were significant differences in quality of sleep related to type of family, number of present illnesses, and use of medication; (c) health promoting behaviors, family functioning, depression, and climacteric symptoms were significantly related to subjective sleep quality; and (d) 34% of variance in subjective sleep quality can be explained by climacteric symptoms, depression, type of family, and spouse. Conclusions: Our findings suggested a high proportion of poor sleeping in middle-aged women. Poor sleeping appeared to have poor health promoting behaviors, lower family functioning, worse depression, and higher climacteric symptoms. Climacteric symptoms, depression, type of family, and spouse were independent risk factors for poor sleeping. Nurse professionals should screen for sleep problems in middle-aged women with a biopsychosocial and behavioral aspect.
