Objectives: Intake of fruits and vegetables has protective effects against stroke attack. This study intended to examine the status of consuming fruits and vegetables and to find out which factors may influence the frequency of consumption of fruits and vegetables in individuals with a history of stroke. Methods: The data of 208 subjects from 5th (2010, 2011) Korea National Health and Nutrition Examination Survey (KNHNES) who reported a stroke diagnosis was used for analysis. To identify major factors influencing the consumption of fruits and vegetables, a classification-tree analysis was carried out. Results: Among those who reported a stroke diagnosis, the frequencies of consumption of fruits and vegetables were influenced by their age, place of residence (urban or rural), economic status, educational level, occupation, number of family members, frequency of eating out, and having meals (breakfast or lunch) with family members. Two factors from fruits and three factors from vegetables were generated by exploratory factor analyses. Urban residents ate fruits and vegetables more frequently in all factors than rural residents. Eating frequencies of 'seasonal fruits (orange, apple, strawberry, melon, pear and watermelon)', 'easily-accessible fruits (persimmon, tangerine, grape, peach, banana)', and 'Western-style vegetables (cabbage, mushroom, carrot, tomato, spinach)' were influenced by the socioeconomic status. Eating frequencies of 'Korean-style vegetables (bean sprout, radish leaves, pumpkin/squash, sea weed)', 'preserved vegetables (Korean cabbage, radish, laver, cucumber)' were influenced by having breakfast with family members. Conclusions: The results of this study suggested that by eating more fruits and vegetables, more preventive effects against secondary stroke attack are expected in stroke patients who live in the rural areas and who do not eat breakfast with family members. In addition, more outreach and education programs are needed for them.

This study investigates the relationship between vitamin C intake and obesity prevalence among Korean adults. Based on data of the Korean National Health and Nutrition Examination Survey (2016-2017), a total of 1,356 participants were included in this analysis. Increasing the dietary vitamin C intake resulted in a significantly decreased occurrence of BMI obesity prevalence (p for trend=0.0194) and WC obesity prevalence (p for trend=0.0452). Moreover, increasing the dietary vitamin C intake of Korean adults having a high frequency of eating breakfast resulted in significantly decreased BMI obesity prevalence (p for trend=0.0406) and WC obesity prevalence (p for trend=0.0432). Among the Korean adults who ate out frequently, decreased BMI obesity prevalence was determined with increased intakes of dietary vitamin C (p for trend=0.0193) and total vitamin C (food and dietary supplements) (p for trend=0.0429), whereas significant decrease in WC obesity prevalence was observed with increased dietary vitamin C intake (p for trend=0.0484). Our results provide conclusive evidence that consumption of dietary vitamin C is associated with obesity prevalence in Korean adults, according to their habits of eating breakfast and frequency of eating out.

Objective: This study was performed to evaluate gender and age differences in hygienic behavior among the general population, focusing on hand-washing habits and the microbial load of hands. Methods: A self-administered questionnaire survey and a separate microbial examination were performed. The Pearson's correlation between hand-washing habits and microbial load was analyzed. Results: In the questionnaire survey on hand-washing habits, gender differences were found in hand-washing frequency, use of hand-washing agents, and hand drying methods (p<0.05). Age differences were found in numbers of washing parts of the hands and also in hand drying methods (p<0.05). Females showed better habits washing hands than did males, as did older people compared to younger. In the microbial examination of indicator bacteria on their hands, younger people tended to show a higher load of total aerobic bacteria than did the older, and females showed a higher load of total coliforms than did males (p<0.05). There were significant relationships between the load of total aerobic bacteria and hand-washing frequency, duration, and method of turning-off water (p<0.05). Conclusions: Although females were expected to show a better practice of hand-washing than were males based on the survey results, they showed a higher level of total coliforms in the hand examination. The older age group showed better hand-washing habits than did the younger age group and had less total aerobic bacteria on their hands. These inter-gender and age differences highlight the need for development and implementation of gender-and age-specific educational programs or campaigns.

Purpose: The purpose of this study was to investigate the characteristics and grip strength of people with osteoarthritis and rheumatoid arthritis using data from the Korea National Health and Nutrition Examination Survey. Methods: This was a retrospective study that analyzed raw data from the first year of the 8th Korea National Health and Nutrition Examination Survey (2019). The study population was 780 people in total, ranging in age from their teens to their 80s. These were people who had been diagnosed with osteoarthritis and rheumatoid arthritis, and the presence of arthritis in and grip strength of these subjects were determined using the average value of three measurements. Results: According to the National Health and Nutrition Examination Survey, the prevalence of arthritis in Korea was 2.5% in men, 10.7% in women, and 13.1% overall. More women than men had osteoarthritis and rheumatoid arthritis, and the number of people with osteoarthritis increased with age. In this study, of those with osteoarthritis, 13.5% were men and 88% were women; of those with rheumatoid arthritis, 19.3% were men and 56.3% were women. The number of patients with osteoarthritis increased with age, and rheumatoid arthritis was more common in older people. Subjects with osteoarthritis had lower grip strength than those without the disease, and the older the age at which rheumatoid arthritis was first diagnosed, the lower the grip strength. Conclusion: Grip strength is lower in patients with osteoarthritis than in those without osteoarthritis, and it is possible to estimate the degree to which muscle strength decreases.

BACKGROUND/OBJECTIVES: The aim of this study was to estimate average total fat and fatty acid intakes as well as identify major food sources using data from the Korea National Health and Nutrition Examination Survey (KNHANES) VI-1 (2013). SUBJECTS/METHODS: Total fat and fatty acid intakes were estimated using 24-hour dietary recall data on 7,048 participants aged ${\geq}3years$ from the KNHANES VI-1 (2013). Data included total fat, saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA), n-3 fatty acid (n-3 FA), and n-6 fatty acid (n-6 FA) levels. Population means and standard errors of the mean were weighted in order to produce national estimates and separated based on sex, age, income, as well as residential region. Major food sources of fat, SFA, MUFA, PUFA, n-3 FA, and n-6 FA were identified based on mean consumption amounts of fat and fatty acids in each food. RESULTS: The mean intake of total fat was 48.0 g while mean intakes of SFA, MUFA, PUFA, n-3 FA, and n-6 FA were 14.4 g, 15.3 g, 11.6 g, 1.6 g, and 10.1 g, respectively. Intakes of MUFA and SFA were each higher than that of PUFA in all age groups. Pork was the major source of total fat, SFA, and MUFA, and soybean oil was the major source of PUFA. Milk and pork were major sources of SFA in subjects aged 3-11 years and ${\geq}12years$, respectively. Perilla seed oil and soybean oil were main sources of n-3 FA in subjects aged ${\geq}50years$ and aged < 50 years, respectively. CONCLUSIONS: Estimation of mean fatty acid intakes of this study using nationally represented samples of the Korean population could be useful for developing and evaluating national nutritional policies.

Objectives: The aim of the study was to investigate the association of self-perceived oral health and depression in the Korean elderly. Methods: The subjects were 1,329 elderly in Korea from the sixth Korea National Health and Nutrition Examination Survey (the 6th KNHANES). The dependent variable was depression that continued more than two weeks. Model I for the impacts of depression on self-reported oral health, Model II for the impacts of depression on chewing problem, Model III for the impacts of depression on speaking problem was evaluated. PASW Statistics 18.0 version was used for frequency analysis, chi-square test and logistic regression analysis. Results: Female elderly were much more prone to depression than male. Female had lower monthly compensation, less medicaid, chewing problem, speaking problem, and less education. For these reasons, they tended to have more depression than male (p<0.001). Self-perceived oral health impacts on depression included poor self-reported oral health(p<0.01), poor chewing problem(p<0.01) and poor speaking problem(p<0.05). On the other hand, male did not show a statistically significant association. Conclusions: The study showed the self-perceived oral health related quality of life had a significant influence on depression in the elderly. The continuing lifelong oral health care can prevent depression in the later life because oral health care improvement can enhance the self-perceived oral health status.

Background: The aim of the current study was to investigate the factors related to the non-practice of cancer screening in cancer survivors, who are at high risk of developing second cancers. Methods: This study is a cross-sectional analysis of 1,125 cancer survivors ${\geq}19$ years old who participated in the Korean National Health and Nutrition Examination Surveys IV and V (2007-2012). A Rao-scott chi-square test and a survey logistic regression analysis were employed respectively to analyze the difference of cancer survivors in cancer screening by each characteristic and the factors related to the non-practice of cancer screening in cancer survivors. Results: Among total subjects, 33.5% did not participate in cancer screening in the last two years. Results from a fully adjusted logistic model showed that the non-practice of cancer screening in cancer survivors was significantly associated with variables such as sex, age, marital status, education level, monthly income, and drinking a alcoholic beverage Specifically, the odds ratio of non-practice of cancer screening was higher in males than in females, in the younger group than in older group, in the group with no spouse than in the group with a spouse; in a group with a low level of education than in a group with a high level of education; in a group with the lowest income level than in a group with the other levels of income; or in non-drinkers than in drinkers. Conclusion: Health policies to reduce the non-practice rate of cancer screening in cancer survivors should be designed and implemented with close attention to cancer survivors' socio-economic characteristics such as sex, age, marital status, education, and income, along with a health behavioral characteristic as drinking.
