Objectives: The purpose of this study was to assess energy and nutritional intake and investigate the preference for food and cooking methods of the residents in elderly care facilities. Methods: Data were collected from 72 residents (10 males and 62 females) aged ${\geq}70$ years in elderly care facilities using questionnaires, food photographs for estimating dietary intake and records for daily physical activity. Results: Average age of the study participants was 85.0 years and 41, 36 and 8 had dementia, hypertension and diabetes mellitus, respectively. 15%, 65% and 19% of subjects were physically mobile, enervated, and immobile, respectively. Daily energy intake was 1360.2 kcal in men and 1378.0 kcal in women, which were 68.0% and 86.1% of the estimated energy requirement (EER) of dietary reference intake for Koreans (KDRI) for ${\geq}75$ year old individuals, respectively. Estimated energy expenditure (EEE) of subjects calculated using formula from KDRI was 1361.9 kcal and EER calculated using estimated daily physical activity (EDPA) was 1232.9 kcal. Energy intake and EEE from KDRI were higher than EER from EDPA. Dietary intake of dietary fiber, calcium, potassium, zinc, vitamin $B_2$, niacin, vitamin C were lower, and protein, phosphorous, iron, sodium, vitamin A, vitamin $B_1$, vitamin $B_6$, vitamin E were higher than the corresponding ones of KDRI. Subjects liked meats, fishes and shellfish, and fruits, while subjects disliked milk, seaweeds and salted fish and salted vegetables. Cooked rice, soybean paste soup, beef, cooked sliced radish strip, and yogurt were favorite foods, with steam being a favorite cooking method. Subjects considered nutrition as the most important factor for improving food service quality. Conclusions: Results of this study could be utilized for improving food-service for the residents in elderly care facilities, and provide a basis for setting reference intake of energy and nutrients of the elderly having very low activity levels.

Objectives: The objectives of the study were to assess body composition, physical activity level (PAL), basal metabolic rate (BMR), and daily energy expenditure (DEE) and to examine associations between PAL and body composition, BMR, and DEE of elderly in Busan. Methods: A cross-sectional study was conducted among 226 elderly aged 65-93 years. Body composition was measured by Inbody 720. PAL was calculated by daily activity diary. BMR was calculated by Harris-Benedict (H-B) formula, Dietary Reference Intakes (DRI) formula, and Inbody 720 measurement. DEE was calculated by H-B formula, DRI formula, Inbody 720 measurement, and estimated energy requirements (EER) formula. Results: The mean fat free mass (FFM) in elderly men was significantly higher than that in elderly women (p<0.001). The mean percent body fat and fat mass (FM) in elderly women were significantly greater than those in elderly men (p<0.001, p<0.001). The mean PAL in elderly men (1.59) was significantly higher than that in elderly women (1.53) (p<0.001). The mean DEEs calculated by 3 methods except for H-B formula in elderly men were higher than EER for elderly men (2000kcal). The mean DEEs calculated by 4 different methods in elderly women were higher than EER for elderly women (1600kcal). Age showed significantly negative correlations with height (p<0.001, p<0.001), FFM (p<0.001, p<0.001), BMRs calculated by H-B formula (p<0.001, p<0.001), DRI formula (p<0.001, p<0.001) and Inbody 720 measurement (p<0.05 p<0.01) and DEEs calculated by H-B formula (p<0.001, p<0.001), DRI formula (p<0.001, p<0.001), Inbody 720 measurement (p<0.05, p<0.05), and EER formula (p<0.001, p<0.001) in elderly men and elderly women. PAL showed significantly positive correlations with FFM (p<0.05), BMR by Inbody 720 measurement (p<0.05) in elderly men and negative correlations with FM (p<0.05) in elderly women. Conclusions: Based on the results, PAL was associated with greater FFM in elderly men and lesser FM in elderly women. Therefore, nutritional education to increase physical activity for health promotion in late life is needed in the elderly.

This study was conducted to assess dietary pattern and dietary diversity of preschool children by investigating their food consumption. To accomplish this, dietary intake survey (24 hour-recall food diary) was administered to 508 children aged between 4 to 6 years old from 4 kindergartens in the Daegu area (415 were completed). By using CAN pro 3.0 for professionals, the dietary patterns and dietary diversity scores of each food group were examined by age and sex. Data were analyzed with SPSS 12.0, and $\chi^2$, t-test and Anova test, and Duncan's multiple range test used for verifying significance. For 4~5-year-old group, boys had significantly more fruit and meats than girls (p < 0.05), but girls had more dairy food than boys with no significance. For 6-year-old group, boys had significantly more foods, milk and dairy foods than girls (p<0.05), and also boys had more vegetables and fruit than girls with no significance. For DDS (Dietary Diversity Score), the score of 6-year-old group was significantly higher than that of younger children (p < 0.05) and the older the age was, the higher the score was. Dietary Pattern (GMVFD) was verified by 8 types, and the ratio of taking all five food groups (GMVFD = 11111) of the 6-year-old group was 48.8%. Children with older ages had more various foods than younger ones (p < 0.05). In addition, the ratio of taking less than the minimal intake of dairy foods of girls (48.1%) was higher than that of boys (41.3%). As results, unbalanced diet, overeating and not eating unbalanced diet were revealed as the problematic dietary habits among preschool children, and those habits may change positively with knowledge on nutrition grow on. Therefore, nutritional characteristics and importance of preschool children should be taught to parents and caregivers, and it must be practical and ready to use in cooking for these children to healthy dietary habits.

This study conducted through questionnaire and dietary survey by 24-hr recall to 850 adults residing in Samcheok. Subjects were divided into four groups according to the age in male and female, which included 20~29 yrs group (male n = 94, female n = 66), 30~49 yrs group (male n = 201, female n = 216), 50~64 yrs group (male n = 88, female n = 96), and $\geq65$ yrs group (n = 46, female n = 43). In male, 20~29 yrs group had a larger proportion of subjects who skipped breakfast, lunch and dinner compared to other groups (p < 0.001, p < 0.05, p < 0.01). The daily food and energy intakes in $\geq50$ yrs group were significantly lower than those of < 50 yrs. Protein and fat intakes of 20~29 yrs group were significantly higher than those of the other groups. But ND (Nutrient Density) of minerals as like calcium, iron and plant iron in 20~29 yrs group were significantly lower than those of other groups. The KDDS (Korean's Dietary Diversity Score) of 20~29 yrs group, 30~49 yrs group, 50~64 yrs group and $\geq65$ yrs group in male were 4.1, 3.8, 3.7 and 3.5 respectively and there was significant difference (p < 0.001). In female, skipping breakfast and dinner were significantly higher in 20~29 yrs group than in other groups (p < 0.001, p < 0.001). And the use of nutrient supplementation was higher in 30~49 yrs group than that of other groups (p < 0.05). The daily energy intakes was higher in 20~49 yrs group than that of $\geq65$ yrs group. The ND (Nutrient Density) of animal protein, vitamins A and $B_1$ in 20~29 yrs group were significantly lower than those of other groups. The KDDS of 20~29 yrs group, 30~49 yrs group, 50~64 yrs group and $\geq65$ yrs group in female were 4.0, 3.9, 3.9 and 3.6 respectively and $\geq65$ yrs group was significant lower than other groups.

Objectives: This study was conducted to examine blood pressure and other characteristics of a high sodium intake group assessed with 24-hr urine analysis and the dietary factors related to the risk of high sodium intake among Korean adults. Methods: A cross-sectional study was conducted with adults aged 20-59 years. Subjects who completed 24-hr urine collection (N = 205) were divided into 3 groups (tertile) according to the sodium intake estimated with 24-hour urine analysis. We compared the blood pressure, BMI and dietary related factors of the 3 groups (low, medium, high sodium intake group) with General Linear Model (GLM) and Duncan's multiple range test (p < 0.05). The risk factors related to high sodium intake were assessed with odds ratio (p < 0.05). Results: The sodium intake (mg/day) of the 3 groups were $3359.8{\pm}627.9$, $4900.3{\pm}395.1$ and $6770.6{\pm}873.9$, respectively, corresponding to daily salt intake (g/day) 8.5, 12.4 and 17.2, respectively. High sodium group showed significantly elevated age, BMI and systolic/diastolic blood pressure. Being male gender was associated with significantly increased risk of sodium intake (OR = 1.972; 95%CI: 1.083-3.593). The other factors related to high sodium intake were higher BMI (${\leq}25$) (OR = 2.619; 95% CI: 1.368-5.015), current alcohol consumption (OR = 1.943; 95%CI: 1.060-3.564), and having salty soybean paste with salt percentage > 14% (OR = 3.99; 95% CI: 1.404-6.841). The dietary attitude related to increased risk of high sodium intake included 'enjoy dried fish and salted mackerel' (p < 0.001) and 'eat all broth of soup, stew or noodle' (p < 0.001). Conclusions: Because high sodium intake was associated with higher blood pressure, nutrition education should focus on alcohol consumption, emphasis on related dietary factors such as using low salt soybean paste, improvements in the habit of eating dried fish and salted mackerel or eating all broth of soup, stew or noodle.

본 연구는 지난 10년(1995-2005년)동안 급증하고 있는 1인가구의 인구 경제 사회학적 특성에 따른 성장패턴을 기술하고, 1인가구의 다양한 특성에 따른 공간분포 특성을 분석하는데 목적을 두었다. 1인가구의 증가는 젊은 층의 결혼 지연과 독신, 중년층의 이혼율 증가와 노령화에 따른 독거노인의 증가가 복합적으로 작용하였다. 1인가구의 성별, 연령별, 혼인상태별, 교육수준에 따라 상당히 차별적인 1인가구의 성장 패턴을 보이고 있다. 1인가구의 연령, 학력, 주택소유 및 주택유형을 기준으로 하여 이들의 공간분포 패턴을 비교해보면 매우 대조적이고 불균등하게 나타나고 있다. 교육수준이 높고 자가 아파트에 거주하는 젊은 싱글족은 소수의 대도시에 집중해있는 반면에 교육수준이 낮고 단독주택을 소유하고 있는 독거노인들은 주로 농촌에 거주하고 있다. 또한 고학력의 젊은 연령층의 경우 경제적 상황에 따른 양극화 현상이 두드러지게 나타나고 있다. 특히 광역시나 대도시에는 아파트를 소유하면서 경제적으로 여유있는 삶을 살고 있는 그룹과 월세로 단독주택에 거주하는 그룹이 혼재되어 있는 것으로 나타났다. 이와 같이 1인가구들도 상당히 이질적인 특성을 갖고 있기 때문에 어떤 그룹에 속하고 있는 1인가구가 증가하고 있으며, 또 집중분포되어 있는가에 따라서 해당 지자체가 직면하게 되는 경제 사회적 문제는 상당히 다를 것이며, 이에 따른 사회복지정책도 차별화되어야 할 것이다.
