Objective : We estimated the number of Korean adults with back pain and evaluated population-based associated factors of back pain from a representative sample data from the Fourth Korea National Health and Nutrition Examination Survey. Methods : The number of Korean adults who experienced back pain (experienced patients), those who experienced back pain lasting for three or more months during the past year (chronic patients), and those who were currently suffering from back pain (current patients) were estimated by analyzing the data from the fourth Korea National Health and Nutrition Examination Survey conducted in 2007 using surveyfreq procedure of the SAS statistical package. Population-based odds ratios for being experienced, chronic, and current patient according to demographic (age and gender), socioeconomic (education and occupation), and lifestyle factors (smoking, drinking, and exercise) were estimated using surveylogistic procedure. Results : It was estimated that there were 5,554,256 (proportion, 15.4%; 95% CI, 4,809,466 - 6,299,046) experienced patients, 2,060,829 (5.7%; 1,557,413-2,564,246) chronic patients, and 3,084,188 (8.5%; 2,600,197 - 3,568,179) current patients among 36,107,225 Korean adults aged 20-89 years in 2007. Each of explanatory variables was significantly associated with at least one of the response variables for back pain. Conclusion : Based on our study results, further efforts to investigate epidemiology of back pain, to evaluate associated factors, and to improve treatment outcomes are needed.

Opisthorchis viverrini (OV) liver flukes are common parasites found in central and southern Laos and constitute a major public health problem in the country. Laos people continue to have the habit of extensively consuming raw or half-cooked fish which are intermediate hosts. This study aimed to determine the prevalence and factors associated with OV infection in the population of Thakek district, Khammouane Province. This cross-sectional analytic study covered 237 subjects who filled out structured questionnaires. Fecal examination for OV infection was performed by Kato's thick smear method. Data analysis was carried out using STATA Version 10.0. Multiple logistic regression was applied. The results showed that the infection rate of OV was 54.8%. Factors associated with OV infections were gender, a habit of defecation in fields and raw fish (goi bplaa dip) consumption. Opisthorchiasis and associated cholangiocarcinoma development thus appear to remain as important concerns in Laos.

Background: Cervical cancer is the second most common cancer among women worldwide. Failure to prevent cervical cancer is partly due to non-participation in regular screening. It is important to plan and develop screening programs directed towards underscreened women. In order to identify the factors associated with underscreening for cervical cancer among women, this study examined Pap test participation and factors associated with not having a time-appropriate (within 3 years) Pap test among a representative sample of women in Ontario, Canada using Canadian Community Health Survey (CCHS) data. Materials and Methods: Univariate analyses, cross-tabulations, and logistic regression modeling were conducted using cross-sectional data from the 2007-2008 CCHS. Analyses were restricted to 13,549 sexually active women aged 18-69 years old living in Ontario, with no history of hysterectomy. Results: Almost 17% of women reported they had not had a time-appropriate Pap test. Not having a time-appropriate Pap test was associated with being 40-69 years old, single, having low education and income, not having a regular doctor, being of Asian (Chinese, South Asian, other Asian) cultural background, less than excellent health, and being a recent immigrant. Conclusions: Results indicate that disparities still exist in terms of who is participating in cervical cancer screening. It is crucial to develop and implement cervical cancer screening programs that not only target the general population, but also those who are less likely to obtain a Pap tests.

Purpose: Purpose: The prognostic factors of non-operative management (NOM) in high-grade spleen injuries have been extensively studied, but factors that would help treatment decisions are lacking. We compared the characteristics of the patients to identify the factors affecting treatment choices. Methods: This is a review of 207 blunt spleen injury patients from January 2004 to December 2013. We compared clinical features and mortality between surgery and NOM, and used multivariate regression analysis to find the factor most strongly associated with prognosis. Results: Of the 207 patients, 107 had high-grade spleen injury patents (grade III or above). Of these, 42 patients underwent surgery and 65 patients underwent NOM. The mortality was 7% following surgery, 3% with NOM. The amount of packed red blood cells transfused in the first 24 hours and spleen injury grade were associated with management type, and mortality was highly associated with activated partial thromboplastin time (aPTT) and spleen injury grade. Conclusions: The grade of spleen injury was associated with management and mortality, so correctly assessing the spleen injury grade is important.

Purpose: This study utilized secondary data and investigated the factors associated with life satisfaction by living arrangements among community-dwelling adults aged 65 years or older in Korea. Methods: A total of 2,134 participants were selected from the 2014 Korean Longitudinal Study of Aging (KLoSA). Univariable and multivariable logistic regression were used for data analysis. Results: The significant factors associated with life satisfaction in older adults living with others were education level (odds ratio [OR] 1.73, 95% confidence interval [CI] 1.41~2.11), place of residence in medium-size city (OR 1.57, 95% CI 1.25~1.97), place of residence in rural town(OR 1.52, 95% CI 1.19~1.95), depression (OR 2.99, 95% CI 2.43~3.68), frequency of contact with neighbors (OR 1.39, 95% CI 1.10~1.76), and social participation (OR 1.48, 95% CI 1.14~1.93). In contrast, factors associated with life satisfaction among older adults living alone were education level (OR 1.93, 95% CI 1.15~3.24) and depression (OR 2.49, 95% CI 1.48~4.19). Conclusion: These findings indicated that nursing interventions for improving life satisfaction among older adults should take into account their specific living arrangements.

Objectives: This study aimed to investigate the factors associated with unmet dental needs among adults with activity limitations. Methods: Data were obtained from the seventh Korean National Health and Nutrition Examination Survey (KNHANES). The final sample consisted of 945 adults aged 20 years or older with limited activity. Logistic regression analysis was used to examine the influence of predisposing, enabling, and need factors on unmet dental needs. Results: The proportion of adults with unmet dental needs during the last year was 52.2% in the middle-aged group and 45.5% in the older adult group. Higher household income was associated with fewer unmet dental needs in both groups. In the older adult group, married people were less likely to have unmet dental needs. In the middle-aged group, adults who perceived their oral health as poor were more likely to have unmet dental needs. Conclusions: All three factors (predisposing, enabling, and need) were found to be associated with unmet dental needs among adults with activity limitations. Special efforts should be made to improve access to dental care services for middle-aged adults with activity limitations.

Background: Happiness is one of the most important indicators of health, wellbeing, and quality of life among older adults. The objective of the study was to investigate factors associated with happiness among senior citizens residing in rural areas using the 2017 National Survey of Older Koreans. Methods: A cross-sectional analytical study was conducted among 3,149 senior citizens living in rural areas using secondary data from the 2017 National Survey of Older Koreans. Happiness was measured by a single question and responses were recorded dichotomously. Descriptive and inferential statistics were computed at a 5% level of significance. Results: In all, 64.5% of the participants considered themselves as happy most of the time in the last 1 week. In the study, socio-demographic factors did not predict happiness except age. Satisfaction with a health status, financial situation, relationship with children, cultural satisfaction, and satisfaction with friends and society were positively associated with happiness among senior citizens residing in rural areas of Korea. Odds of reporting happiness were higher among those who traveled in the last 1 year, visited elderly welfare centers, and were involved in voluntary work than among those who did not. Conclusion: Happiness among senior citizen was significantly associated with life satisfaction with regard to health, finance, relationship with family, friends and society, and social activity participation.

Purpose: This study investigated the factors associated with suicidal ideation in the Korean Echo Generation using 2012 Korea Health Panel Data. Methods: The 2012 Korea Health Panel Data were collected from February 2012 to July 2012 and included 2,303 people who responded to a question asking whether they had experienced suicidal ideation. The data were analyzed by chi-square and multiple logistic regression test using SPSS 22.0. Results: The rate of suicidal ideation was 4.2% in the Echo Generation. Factors associated with suicidal ideation in the Echo Generation revealed that the following variables increased the rate of suicidal ideation: sex(odd ratio: 2.39, CI: 1.39-4.09), education(odd ratio: 1.95, CI: 1.08-3.52), depression(odd ratio: 12.06, CI: 6.92-21.03), frustrating experience(odd ratio: 2.52, CI: 1.22-5.20), anxiety about the future(odd ratio: 14.58, CI: 3.20-66.41), self-rated health status(odd ratio: 2.39, CI: 1.39-4.09 and odd ratio: 6.41, CI 2.87-14.33). Conclusion: This study provides a preliminary examination of the factors associated with suicidal ideation in the Echo Generation. A more careful examination may be warranted.

This study was performed to investigate the related dietary factors associated with hypercholesterolemia in postmenopausal Korean women. The study sample comprised 455 postmenopausal women aged40 $\leq$ < 65. The hypercholesterolemic (serum cholesterol $\geq$240mg/dl group (N = 82) showed significantly higher BMI and waist circumference compared to the normal group (N = 373). However, both group did not show any significant difference in energy intake but hypercholesterolemic group demonstrated significantly lower intakes of fat and vitamin A with higher intake of vitamin C. Significant dietary factors associated with the higher risk of hypercholesterolemia included consumption frequencies of light color vegetable more than 3.79times/day (OR = 4.62 ; $95\%$ CI : 2.96 - 7.22), dried squid more than 0.08time/day (OR = 1.63 ; $95\%$ CI : 1.13 - 2.35), and beer more than 0.03time/day (OR = 1.57 ; $95\%$ CI : 1.01-2.43). Whereas consumption frequency of yellow and green leafy vegetables more than 1 time per day was associated with the significantly lower risk of hypercholesterolemia (OR = 0.06 ; 95 CI : 0.038 - 0.101).
