2001년에 실시할 $\ulcorner$국민건강.영양조사$\lrcorner$를 위한 새로운 표본설계를 하였다. 본 표본설계에서는 표본의 대표성을 높이기 위해서 기존의 표본가구수는 유지하면서 표본조사구를 증가시키고 새로운 지역 층화변수를 추가로 도입하였다. 또한 추정량의 추정오차 공식을 유도하여 추정의 신뢰성을 측정할 수 있도록 설계하였다.

바람직한 식생활은 질병을 예방하고 건강을 증진시킨다. 이에 식생활의 중요성이 강조되면서 국민 누구나 쉽게 이해하고 실행할 수 있는 식생활 지침이 각 기관에서 발표되었다. 그러나 그 활용도에 대한 분석결과가 없고 식생활 지침의 홍보도 현실적으로는 매우 미약한 수준이라 식생활 지침의 국민 건강증진에 대한 효과성 파악이 어려운 실정이다. 그러므로 본 연구는 식생활 지침의 활용도를 높이기 위한 전략사업의 기초로 일반인을 대상으로 식생활지침에 대한 인지정도를 조사하였기에 보고하는 바이다. (중략)

A total of 5,597 Korean subjects aged 20-64 years were analyzed using the KNHANES 2013-2015. Among the subjects, 41.1% of males and 5.5% of females were smokers, and risk of developing metabolic syndrome in smokers was significantly increased in men with age, alcohol, physical activity, obesity, and sleep(aOR 1.785, 95% CI 1.004-3.174), whereas it was not significantly higher in women. As a result of analyzing the difference of average nutrient intake according to smoking and metabolic syndrome, the energy, retinol and vitamin C intake were significant when age and gender were corrected in the smoker and metabolic syndrome group. In this study, we found that smoking behavior and metabolic syndrome were related to nutrient intake which requires a national level of lifestyle intervention for the prevention and management of metabolic syndrome.

This study was conducted to analyze the relationship between the levels of lead (Pb) exposure and cardiovascular disease (CVD) in Korean adult women. We used cross-sectional data on blood lead and self-reported diagnoses of ischemic heart disease (IHD), stroke and hypertension in a subsample of 1.821 adults 19 years and older who participated in the 2017 Korea National Health and Nutrition Examination Survey (KNHANES). CVD and blood Pb concentrations were analyzed through logistic regression analysis, and correlations between factors were confirmed using the pearson correlation coefficient. An increase of blood Pb was associated with an increased risk of IHD (OR 5.68, 95% CI 1.01-17.51) and hypertension (OR 3.37, 95% CI 2.24-5.07) only in women. Additionally, there was a correlation between blood Pb and nutrient intake. This suggest that blood Pb levels may be used as a key predictor of CVD development, and that women are more susceptable to IHD and hypertension associated with Pb exposure.

The purpose of this study was to explore factors influencing quality of life among cancer survivors in order to identify strategies for cancer survivors to go back to normal life and carry on stable and high quality life. This study used Korea National Health and Nutrition Examination Survey(2010-2014), conducted by Korea Centers for Disease Control and Prevention(KCDC). The sample of this study was 610 cancer survivors and their average time since diagnosis was about 11 years. The most powerful influencing factors for quality of life among cancer survivors were activity limitation(${\beta}$=.30, p<.001), followed by age(${\beta}$=-.20, p<.001), subjective health status(${\beta}$ =-.19, p<.001), and economic status(${\beta}$=.12, p=.004). According to the result, limitation on daily activities or social activities due to physical or mental debilitation was a strong factor that lowers quality of life among cancer survivors. Hence, there is a need for manpower and infrastructure that facilitates, supports, and manage daily activities of cancer survivors.

The purpose of this study was identify the factors affecting serum vitamin D deficiency in korean women. This study used the data from the 5th Korea National Health and Nutrition Examinations Survey and analyzed the demographic characteristics, health related factors and serum vitamin D in women aged 19 and over. Data were analyzed using the IBM SPSS 18.0 program. As a result, vitamin D deficiency rate in Korean women was 81.4%. There were significant differences according to age, marital status, region, type of residence, family income, education level. The risk factors of vitamin D deficiency were age, marital status, region, without walking. According to the results of this study, further studies on the vitamin D deficiency factors by age group should be conducted and the stress relieve and physical activity of women should be promoted to prevent vitamin D deficiency.

The purpose of this study is to identify the factors influencing the depression in workers with diabetes mellitus. Using data from the Korean National Health and Nutrition Examination Survey (KNHANES). 685 workers with diabetes mellitus who were ≥30 years of age were enrolled. Depression was evaluated on the basis of PHQ-9 levels. Data were analyzed by complex sample linear regression using SPSS/WIN 23.0. The factors influencing depression included gender, age, household type, household income level, education level, type of employment (p>.05). The additional factors included stress perception level, weekly walking days (p>.05). Therefore, it is necessary to prepare systematic programs for depression and a support system for health promotion plan for diabetes mellitus in work places and throughout society. In addition, research on depression management program development is needed.

Objectives: This study used an efficient data mining algorithm to explore association rules between the lifestyle risk behaviors and multimorbidity (having more than one chronic disease) in Korean adults. Methods: We used data from the 8th Korean National Health and Nutrition Examination Survey(2019-2020) for 7,609 adults aged ≥19 years. This study was undertaken where 6 lifestyle risk behaviors and 11 morbidities were analyzed using R and Rstudio for the ARM. Results: Among 117 association rules, combinations of hypertension, dyslipidemia and diabetes, hypertension were important role in inadequate sleep, physical inactivity and inadequate weight. Conclusion: The findings of this study are significant because they demonstrate the importance of lifestyle risk factors and the role of multiple chronic diseases using big data analytics such as association rule mining. We recommend developing selective and focused health education programs, such as exercise programs to address physical inactivity, dietary interventions to address inadequate weight, and mental health education programs to address inadequate sleep.
