This study is aimed at examining the status of seafoods intake and preference to actively use the seafoods with high nutritional values and preference. For this purpose, this study conducted a questionnaire survey. The demographic features of the respondents are as follows: male and female high school students were 50%, respectively; first graders were 33.3%, second graders were 35.0% and third graders are 31.7%; the primary dietary-care giver was mother in 80% of the respondents. The survey results on seafood intake at home showed that the most frequently responses to the question of the degree of liking seafood were 'on average' and 'like it', respectively in order. The reason for preferring seafood is 'because it tastes good' in 43.7% of the respondents. Both male and female respondents answered they like seafood for its good taste. With respect to the degree of preference for the seafood provided from the school meals, there were more students who like it than those who do not like it. The most frequent reason to ingest seafood in the school meals is because 'I want to eat it' followed by 'because parents push', 'because friends eat it', 'because health-related TV programs recommend it', respectively in order. The most preferred seafood in the school meals was fried shrimp and the most disliked one is the boiled warty sea squirt. The above results collectively suggest that the preference level for seafood is low and the most preferred one is fried seafood. It is suggested that the nutritionists need to actively develop menu for the students to ingest more various seafoods.

Objectives: This study was designed with the goal of understanding the factors affecting the frequency of skipping meals of prime-aged mothers with children as well as their nutritional status. Methods: Utilizing data from the 2010-2011 Korea National Health and Nutrition Survey, the frequency of skipping meals of mothers aged between 30 to 49 years with children aged between 3 to 11 years during a two day period was statistically analyzed. The number of meals skipped calculated and categorized into skipping no meals, skipping one meal, skipping two meals or more. Results: Compared to subjects who corresponded to mean nutrient adequacy ratio(MAR) of 4 quartile, subjects who corresponded to MAR of 2 quartile had 2.766 (95% CI: 1.552-4.931) probability of being in the 1 meal skippers group, while the probability of being in the more than 2 meals skippers group was 2.743(95% CI: 1.353-5.564). Also, compared to subjects who corresponded to MAR of 4 quartile, subjects who corresponded to MAR of 1 quartile had 3.471 (95% CI: 1.871-6.442) probability of being in the 1 meal skippers group, while the odds ratio for being in the more than 2 meals skippers group was 5.258(95% CI: 2.642-10.466). Conclusions: The results have the advantage of being generalized because the study selected subjects from probability sampling of the female population of Korea. The research results showed that the elements influencing skipping meals of prime-aged mothers with children were mean nutrient adequacy ratio and the number of nutrients, under estimated average requirement intake, and others. Therefore, to encourage dietary behaviors in the right direction, an integrated approach that considers the associated factors must be realized. Future studies are needed to understand how the frequency of skipping meals of mothers affects their children.

Background: This study aimed to explore the associations of social-demographic, health-behavioral, and woman-specific factors with the non-screening status of the cervical cancer screening test in Korean adult women. Methods: This study was a cross-sectional analysis of 9,698 Korean adult women aged 20 years or more who participated in the Korea National Health and Nutrition Examination Surveys V (2010-2012). Rao-Scott chi-square tests and survey logistic regression analyses were employed respectively to analyze the difference in the non-screening status of the cervical cancer screening test by each characteristic and to explore the factors related to the non-screening status. Results: The rate of the non-screening status of the cervical cancer screening test was 53.5% over the previous 2 years. In the survey logistics regression analysis, age, marital status, educational levels, income levels, residential area, occupation, private health insurance, smoking, alcohol, obesity, menstrual status, pregnancy experience, and hormone replacement therapy were significantly associated with the non-screening status of the cervical cancer screening test. Conclusion: On the basis of the results of this study, some social-demographic, health-behavioral, and woman-specific characteristics of Korean adult women seem to affect the non-screening status of the cervical cancer screening test. Therefore, appropriate health policies need to be designed, implemented, monitored, and evaluated to reduce the non-screening status of the cervical cancer screening test of them.

The purpose of this study was to investigate dietitians or nutrition teachers' perception of sugar reduction and usage of sugars in school meal service. A survey was conducted for dietitians or nutrition teachers at elementary, middle, and high schools in Gyeonggi and Incheon. Survey data were analyzed according to the experience period and school types of dietitians or nutrition teachers. The numbers of subjects according to work experience period were 134 (44.2%) for <5 years, 68 (22.4%) for ${\geq}5$ and <10 years, and 101 (33.3%) for ${\geq}10years$. Among the subjects, 168 (55.4%) were nutrition teachers at kindergarten/elementary schools, and 135 (44.6%) were at middle/high/special schools. Perceptions of sugar reduction programs were higher in kindergarten/elementary schools than in middle/high/special schools. The perception of added sugar use increased with more work experience, and interest in sugar reduction was higher in kindergarten/elementary schools than in middle/high/special schools. Practice for added sugar reduction increased with more work experience, and the most common method for reducing sugar was use of natural sugars. The main reason for not reducing added sugars in school meals was due to preference. Nutritional education for students increased with more work experience and was higher in kindergarten/elementary schools than in middle/high/special schools. The major nutritional education methods were using school homepage (37.4%), sending family letters (37.4%), and using principle's discretion time (18.4%). Organic sugar and rice taffy were used more at kindergarten/elementary schools, and white sugar, brown sugar, and white syrup were used more at middle/high/special schools. The most common menu using added sugars was stir-fried dishes (stir-fried pork, chicken, and vegetables).

The purpose of this study was to analyze a cohort, age, and time effects on sodium and sodium-calorie intake using the 2007~2017 Korea National Health and Nutrition Examination Survey (KNHANES). For analysis, we have constructed cohort panel data that combine KNHANES data in a time series. The age effect gradually increased from age 45~49 and then decreased afterwards. The time effect showed an increase in average sodium intake until 2010 followed by a subsequent decrease. The cohort effect showed that the sodium intake was the highest for the War of Liberation 1946~1953, and that the younger the latter, the lower the sodium intake. According to a cohort analysis, the younger the generation, the lower the sodium intake compared to the calorie intake, according to the baby boomers. Based on the results of this study, efforts should be made to educate and promote the dieting and providing low-salt meals to reduce sodium intake by generation. An analysis of the health hazards including sodium by generation and age is thought to enable the establishment relevant policies.

This study assessed the association between vitamin D sufficiency (serum 25(OH)D ${\geq}30ng/mL$) and alcohol consumption using data from the Korea National Health and Nutrition Examination Survey conducted in 2009. The following characteristics were obtained in 7,010 Korean participants ${\geq}19$-years-of-age: serum 25(OH)D level, alcohol consumption (drinking frequency, drinking number of alcoholic beverages on a typical occasion, average daily-alcohol intake), and potential confounders (age, residence, housing status, occupation, total fat and lean mass, smoking, physical activity, history of liver diseases, liver function, and daily intake of energy, protein, and calcium). After adjusting for confounders, vitamin D sufficiency in men was significantly associated with drinking frequency, number of alcoholic drinks consumed, and average daily alcohol intake; odds ratio of 1.21-1.72, 2.17-3.04, and 2.27-3.09, respectively. Increase in the three alcohol drinking-related behaviors was also linearly associated with increase in serum 25(OH)D level in men. By comparison, there was no significant association between alcohol intake and serum 25(OH)D level in women. The positive association between vitamin D sufficiency and alcohol consumption was evident only in Korean men.

BACKGROUND/OBJECTIVES: There are few studies that forecast the future prevalence of obesity based on the predicted prevalence model including contributing factors. The present study aimed to identify factors associated with obesity and construct forecasting models including significant contributing factors to estimate the 2020 and 2030 prevalence of obesity and abdominal obesity. SUBJECTS/METHODS: Panel data from the Korea National Health and Nutrition Examination Survey and national statistics from the Korean Statistical Information Service were used for the analysis. The study subjects were 17,685 male and 24,899 female adults aged 19 years or older. The outcome variables were the prevalence of obesity (body mass index ${\geq}25kg/m^2$) and abdominal obesity (waist circumference ${\geq}90cm$ for men and ${\geq}85cm$ for women). Stepwise logistic regression analysis was used to select significant variables from potential exposures. RESULTS: The survey year, age, marital status, job status, income status, smoking, alcohol consumption, sleep duration, psychological factors, dietary intake, and fertility rate were found to contribute to the prevalence of obesity and abdominal obesity. Based on the forecasting models including these variables, the 2020 and 2030 estimates for obesity prevalence were 47% and 62% for men and 32% and 37% for women, respectively. CONCLUSIONS: The present study suggested an increased prevalence of obesity and abdominal obesity in 2020 and 2030. Lifestyle factors were found to be significantly associated with the increasing trend in obesity prevalence and, therefore, they may require modification to prevent the rising trend.

This study examined the relationship between dietary supplements and nutritional status, as well as the risk of metabolic syndrome among elderly (aged 65 and older) household types, using data from the 7th Korea National Health and Nutrition Examination Survey. Across all household types, dietary supplement users had a higher intake of vitamins and minerals, compared to non-users. As a result, a significant decrease was observed in the prevalence of individuals with nutrient intakes below the stimated average requirement (EAR), particularly in single-person and multi-generation households. In single-generation households, non-users had higher HDL cholesterol levels than the other groups, while users had significantly lower cholesterol levels. Adjusting for gender and age, supplement consumption among the elderly decreased the risk of low HDL cholesterol levels, indicating a potential association with lower metabolic syndrome risk (OR=0.798, P=0.006). In conclusion, the use of dietary supplements among the elderly may improve their nutritional status, particularly in single-person and multi-generation households facing higher risks of nutritional deficiencies. In addition, the utilization of dietary supplements can reduce the risk of low HDL cholesterol in single-generation households.

The purpose of this study was to analyze the factors affecting the unmet dental needs of Koreans. In relation to the subjects and methodology for this study, the data from the 5th national health nutrition survey which had been conducted between 2010 and 2012 were analyzed by using the PASW statistics 18.0 (SPSS Inc., Chicago, IL, USA), a statistical program, through the frequency analysis of complex samples, cross analysis of complex samples, and logistics regression analysis of complex samples. The results of analysis showed that the rate of unmet dental needs stood at 35.3% of all subjects. Moreover, to determine the factors related to the unmet dental needs, the logistics regression analysis of complex samples was conducted. The results of analysis showed that the demographic and socio-economic factors and oral health condition factors had relationship with unmet dental needs. It is necessary to consider all the objective dental treatments that reflect specific dental diagnosis from a comprehensive standpoint.

Objectives: This study was performed to investigate the associations of food security with socio-demographic characteristics, nutrient intakes and mental health status among older Korean adults. Methods: This study was conducted using data from the 2008-2010 Korea National Health and Nutrition Examination Survey (KNHANES). Subjects were 4,451 adults aged 65~98 years. Food security was measured using a self-reported question on food sufficiency of subjects' household. Based on the answers, study subjects were classified into secure, mildly insecure, moderately insecure, and severely insecure groups. Dietary intake was estimated by 24-hour dietary recall. Nutrient intake was assessed by dietary reference intakes (DRI). As for mental health status, the data on mental stress, depression, and suicide ideation were used. Results: Rate of food insecurity in older adults was 14.3%. Old age, being female, low education, low income level, living alone, and discomfort in daily living were more related to food insecurity. Means of nutrient intakes were significantly different according to food security status. Intakes of calcium, potassium, and vitamin $B_2$ were lower than recommended intakes in all groups. Consumption amounts of soy and soybean products, vegetables, mushrooms, fruits, vegetable oils, meats, eggs, seafood, and dairy products were lower in food insecure groups. Mental stress, depression, and suicide ideation were higher in food insecure groups independent of the gender and income level. Conclusions: These present findings suggested that food security is related to mental health as well as nutrition status in older Korean adults. A national system that include food and psychosocial support programs for the elderly should be considered in order to improve the overall health of older Korean adults.
