  • The purpose of this study was to estimate seasonal variation of nutritional intake and quality in adults in longevity areas. Dietary survey was given to 469 subjects over age 20 living Bukjeju-gun, Yecheon-gun, and Sunchang-gun of Korea, using 24-hour recall method every 4 seasons over one-year period. The mean daily intakes (%RDA) of 4 seasons were 1313.3 ㎉ (72.0%) for energy, 47.3 g (82.2%) for protein, 20.2 g for fat, 228.0 g for carbohydrate, 12.8 g for dietary fiber. The differences were hardly significant among the seasons. Mean daily intakes of most of the vitamins and minerals were lower than RDA except vitamin C and folate, especially %RDAs of Ca, vitamin D, vitamin B$_2$, vitamin E were less than 60% of RDA. In general, nutrient intake were high in spring compared to other seasons except vitamin C which was high in fall and winter. Mean daily intakes of cholesterol were 151.7 mg and 124.3 mg in males and females, respectively. The differences was significant between the two sexes but not among the seasons. PUFA : MUFA : SFA ratio of the subject was 1.0 : 1.3 : 1.2. Average CPF ratio of energy intake was 72.7 : 14.4 : 12.9, and energy intake ratio from carbohydrate was low in spring, in contrast energy intake ratios from protein was significantly high in spring. Mean adequacy ratio (MAR), an index of overall nutritional quality was 0.64 for female and 0.71 for male. The indices of nutritional quality (INQ) were over 1 for most of nutrients except 0.73 of Ca, 0.87 of vitamin A, 0.69 of vitamin B$_2$, and 0.65 of vitamin E. Both MAR and INQ were significantly different among sex and seasons, values were higher in males than in females and were higher in spring with the exception of vitamin C. In conclusion, subjects in longevity areas did not consume enough nutrients quantitatively as well as qualitatively, especially Ca, vitamin A, vitamin B$_2$, and vitamin E. Also mean daily intakes of most of vitamins and minerals were insufficient in females, and were significantly different among season. Therefore we must consider a counterplan to augment nutrition intake for them. In addition, it seems to be essential to micro nutrients to the food composition database to estimate dietary intakes more accurately.

  • The aim of this study was to investigate the eating behavior and nutritional status of subjects according to their purpose of exercise. A total of 214 subjects, 20 to 30 years of age, who visited fitness centers in Seoul were enrolled. Anthropometrics, exercise habits, nutritional knowledge, and eating behaviors were analyzed using a questionnaire. Nutritional status was assessed by serial 24 h recalls. The subjects were divided into two groups based on their purpose of exercise: increasing muscle (Muscle growth, n=107) or losing body weight (Weight loss, n=107). The Muscle growth group contained a higher percentage of men, whereas the Weight loss group contained a higher percentage of women. The Muscle growth group showed significantly higher scores of nutritional knowledge and eating behaviors compared to the Weight loss group. The Muscle growth group also had a significantly higher intake of energy and protein compared to the Weight loss group. In fact, the intake of energy in the Weight loss group was lower than the estimated energy requirement (EER) for both men and women subjects. The intake of protein in the Muscle growth group was twice as much as the recommended nutrient intake (RNI). The intake of calcium in both groups was less than the RNI. In conclusion, those who exercised with the aim of increasing muscle took excess dietary protein and those who exercised with the aim of weight loss had a lower energy intake than the EER.

  • Purpose: This study examined the demographics, health status, dietary habits, energy, nutrient intake, and protein intake based on levels of inclusion of animal food among females in their 20s by using data from the 7th Korea National Health and Nutrition Examination Survey. Methods: The subjects (n = 912) were divided into 4 groups according to the frequency of animal foods consumed which were categorized as meat, seafood, eggs, and dairy products, or other animal-derived foods. Results: The subjects with a lower frequency of animal food intake ate out less frequently. As the frequency of animal food intake decreased, the total energy intake too decreased with higher carbohydrate and lower protein intake ratios. In the low frequency of animal food intake group, a higher proportion of subjects had energy intake below the estimated energy requirement and the intake of protein, vitamin B1, vitamin B2, niacin, calcium, phosphorus, and iron were below the estimated average requirements. The average protein intake was more than the recommended 45 g in all four groups. However, the lower the frequency of animal food intake, the higher the proportion of people having lower protein intake compared to the recommended intake of 0.91 g per kg body weight. It became apparent that people who do not consume animal foods at all did not meet the recommended levels of protein intake. Thus, people pursuing a vegan diet may be at risk of low protein intake. Conclusion: This study suggests that economic characteristics, dietary habits, energy, and nutrient intake are affected by the frequency of animal food consumed, or in other words, by the degree of vegetable-centered diet. Thus, this study would help improve the perception of vegetarianism, develop individualized dietary guidance and nutrition education programs for people practicing vegan or vegetarian diets to ensure that they have a balanced diet.

  • This study was carried out to investigate health status and nutritional status based on dietary intake and food habit of elderly women in rural area of Keyonggi Province. The subject of this study were 133 elderly women aged 60 and over and interviewed with a questionaire. Main result was as follows : 1) Health score based on modified Cornell Medical Index, CMI(45 out of 195 items) was the average $29.1\pm6.8$ and was not significantly different with family size educational level and farmwork participation. In age, 44.0% of the subject in 60~65 years old was low score of CMI(11~25), but 50% of the subject in older than 80 years old was high score(33~44). The subject with disease was 82% and disease of musculoskeletal system was main type. 2) Dietary intake data obtained by a semiquantitative food frequency questionaire showed the average daily intake of energy, protein, Ca, retinol and riboflavin was lower than RDA Daily energy, protein and Ca intake was individually 84%, 67% and 55.1%. It was retinol that was the least sufficient as 49.1% of RDA. 3) The relation between CMI score(divided into three level : low, middle and high) showed low level was significantly different with others according to daily intake of energy, protein, retinol, thiamin, riboflavin and ascorbic acid. The correlation between CMI score and all nutrient intake were highly significant (p<0.001), thus we knew that health status was affected importantly by nutrient intake. 4) Family size, educational level and age showed not significant correlation with all nutrient intake. 5) In food habit, 84.8% of the subject had regular mealtime and 14.4% were skip meal sometimes. The main reason of skip meal was a poor appetite. Preference for salty taste of subject was insufficiently salty of somewhat salty. Preference for fishes and meats showed the subject consumed fishes more than meats, but 23.5% of the subject didn't consume both. The subject eaten supplement was 38.3%.

  • 본 연구는 고학력 중년 여성을 대상으로 취업 여부에 따른 영양섭취 상태의 차이를 분석하여 고학력 중년 여성의 영양 및 건강관리를 위한 대책 마련의 기초자료로 활용하고자 시행되었다. 연구 대상자의 선정은 유의추출 방법으로 전업 여성은 고학력자 비율이 높은 대전시의 일정 지역에 거주하는 기혼여성으로 하였고, 취업여성은 여러 직업의 특성으로 인한 교란(confounding)을 줄이기 위하여 고학력 여성의 비율이 높은 기혼의 교사로 한정하였다. 연령에 의한 교란을 방지하기 위하여 연령대별로 동일 비율로 무작위 추출하여 전업여성 250명, 취업여성 236명을 대상으로, 24시간 회상법을 이용하여 조사 전일 하루동안의 식이 섭취 내용을 개별 면담으로 조사하였다. 1일 영양소 섭취 조사 결과 취업여성은 전업여성에 비해 인, 비타민 B$_1$, B$_2$를, 전업여성은 취업여성에 비해 지방 및 동물성 지방, 나트륨, 비타민 C, 엽산을 많이 섭취하고 있었다. P/M/S비는 전업여성 1/1.19/1.05, 취업여성 l/l.05/0.87로 나타나 취업여성이 전업여성에 비해서, 그리고 한국인 영양권장량의 기준(1/1/1)에 비해서 포화지방의 비가 낮았다. 또한 지방 에너지 구성비도 전업여성(24.38%)이 취업여성(23.29%)에 비해 높았고, 총 열량에 대한 동물성 지방의 섭취비율이 전업여성 12.44%, 취업여성 11.46%으로 나타나 전업여성이 취업여성에 비해 동물성 지방, 포화지방비, 지방에너지 구성비가 모두 높았다. 영양권장량에 대한 영양소 섭취 백분율에서 전업여성과 취업여성 모두 칼슘과 아연을 권장량에 비해 낮게 섭취하고 있었고, 질적 영양지수(INQ)도 두 군 모두에서 칼슘이 가장 낮게 나타났다. 인의 영양밀도(Nutrient Density)가 취업주부에서 높았던 점 외에는 영양밀도와 영양소 적정섭취비(NAR) 모두에서 비타민 B$_1$, B$_2$가 전업여성에 비해 취업여성이, 비타민 C가 취업여성에 비해 전업여성이 더 높았다. 한편 두 군 모두 INQ가 가장 높은 영양소는 인이었고, INQ가 가장 낮은 영양소는 칼슘으로 나타났으며, INQ가 1 미만인 영양소는 칼슘과 함께 철분으로 나타났다. 이는 1998년도 국민건강영양조사 결과에서 45세 이상 여성의 경우 관절염, 요통.좌골통, 디스크 등 근골격계질환 유병률이 남자보다 3배정도 높게 나타난 결과에 비추어볼 때 이들 관련 영양소에 대한 섭취 방안 지도의 필요성을 제시하고 있다. 결론적으로 고학력 중년 여성중 전업여성에 대해서는 지방 특히 동물성 지방 식품 섭취에 대한 적절한 영양교육과 식사관리 지도가 요구된다 하겠다. 또한 고학력 중년 여성은 취업 여부에 관계없이 칼슘과 철분이 많이 함유된 식품으로 식사량을 증가시켜 주는 영양 지도 및 영양 보강 대책이 요구되며, 칼슘과 인의 적정섭취비가 되도록 인의 섭취를 낮추는 식생활 지도가 필요하다.

  • Purpose: The purpose of this cross-sectional study was to assess the nutritional states and investigate the energy intake of tube-fed patients with severe neurodevelopmental disability. Methods: Eighty six tube-fed patients with severe neurodevelopmental disability were studied. Heights were measured by flexible scale segmentally. Nutritional parameters of weight, triceps skinfold thickness and mid-arm circumference were also measured. Total caloric intakes through the tube were calculated. Results: The anthropometric results showed that nutritional states of tube-fed patients with severe neurodevelopmental disability were poor. The mean daily caloric intake was much less than daily energy requirement (mean=45.2% of requirement). The caloric intake was 7.2 kcal/height (cm), 57.0 kcal/weight (kg). Height was more related with caloric intake (r=0.476) than weight (r=0.263). Conclusion: These results provide that tube-fed patients with severe neurodevelopmental disability were growth retarded and their energy intakes were much less than daily energy requirements. The preliminary evidence was that they need adequate nutritional supply.

  • The purpose of this study was to investigate the regional differences in anthropometric measurement, dietary behavior and nutrient intake among the nation-wide college students participating in a nutritional education program via internet. The subjects were 1614 college students (male: 752, female: 862) and divided into 4 regional groups. A cross-sectional survey was conducted using a self administered questionnaire, and the data were collected via internet or by mail. The nutrient intake data collected from food record were analyzed by the Computer Aided Nutritional Analysis Program. Data were analyzed by SPSS 10.0 program. Average age of male and female college students were 23.6 years and 21.0 years, respectively. Most of the male and female college students had poor eating habits, such as unbalanced meals and skipping meals. In particular, more than 60% of the male college students in Chungcheong and Gyeongsang areas had irregularity of meal time. Female students in Seoul and Incheon areas showed significantly higher consumption frequency of yellow and green leafy vegetables compared to Chungcheong and Gyeongsang areas. Female students in Seoul, Incheon and Chungcheong areas showed significantly higher consumption frequency of milk and milk products compared to Gyeongsang area. Calorie, vitamin A, calcium and iron intakes of the male students and calorie, vitamin A, vitamin $B_2$, niacin and calcium intakes of female students were lower than the Korean RDA. Female students in Incheon area showed significantly higher vitamin C and iron intakes compared to the other areas. These results provide a nation-wide information on dietary behavior and nutrient intake among Korean college students.

  • This study was intended to investigated the relationship between habitual physical activity, nutrients intakes and urinary riboflavin excretion of elderly women and to compare riboflavin biochemical status of urban elderly women with rural elderly women. While average daily riboflavin intake of elderly women subjects was below Recommended Dietary Allowances for Koreans, riboflavin biochemical status was adequate in terms of average urinary riboflavin excretion. Urinary riboflavin excretion did not show significant correlation with energy expenditure, physical activity level and riboflavin intake. Nutrients intakes of urban and rural elderly women were not significantly different. However, energy expenditure and physical activity level were significantly higher, urinary riboflavin excretion was significantly lower in rural than in urban elderly women. It is suggested that riboflavin biochemical status was influenced by physical activity.

  • This study was performed to investigate the prevalence of metabolic syndrome (MS) and assess nutrient intake levels for the purpose of improving MS risk factors. The participants in this study were 512 adults consisting of 271 men and 241 women aged 30 and over, who visited a public health center for a medical check up. The diagnosis of MS subjects was adapted from the NCEP-ATPIII guidelines and the WHO Asia-Pacific Area criteria for obesity. The MS group was defined as subjects displaying three or more risk factors, and the non MS group was defined as those displaying two or less risk factors. A dietary survey was conducted using the 24-hour recall method. The number of subjects displaying MS syndrome factors was 158 (30.9%), broken down into, 89 men and 69 women. Regarding risk factors in the MS group, the prevalence of waist circumference was 40.5%, hypertension 34.2%, hyperglycemia 31.0%, low HDL-cholesterol 24.7%, and hypertriglycemia 19.6%. BMI, sistolic blood pressure, blood glocose, blood triglyceride, and blood HCL-cholesterol of the MS group were significantly higher compared to the non MS group. Male subjects in the MS group reported high intakes of cereals, sugar, fruits, meat and poultry, oil and fats, and beverages and total food intake was significantly higher compared to the non MS group. Women in the MS group reported high intakes of meat and poultry, milk and dairy products, beverages, and seasonings, and total food intake was higher compared to the non MS group. Dietary diversity score (DDS) was 3.82~4.04, which was not significant among the groups. In men, dietary variety score (DVS) was 16.3 in the MS group and 19.4 in the non MS group, whereas in women, the DVS was 15.2 in the non MS group and 17.0 in the MS group. In GMVDF pattern, 11111 pattern was 30.7%, followed by 01111 for men and 11101 for women. Calorie, fat, and cholesterol intakes in men as well as, calorie, fat, and folate intakes in women in the MS group were higher compared to the non MS group. Intakes of protein, P, Fe, Na, vitamin $B_1$, vitamin $B_2$, niacin, vitamin E, and Zn were higher than the KDRIs. On the other hand, intakes of Ca, K, fiber, vitamin $B_2$, and vitamin C were below the KDRIs. Intakes of lipids, animal food, Na, and cholesterol in the MS group were higher compared to the non MS group, whereas intake of dietary fiber was lower. Our results indicate that continuous, systematic nutritional education program must implemented to reduce the risk factors associated with MS.

  • This study examined yearly trend of sugar-sweetened beverage(SSB) intake and compared nutritional status by SSB intake level in middle school students aged 12~14 years(n=2,543) using the data from 2007~2015 Korea National Health and Nutrition Examination Survey. SSB included carbonated drinks, sports drinks, and caffeinated drinks contained added sugar. Subjects were classified into three groups by SSB intake level obtained from 24-hour recall method: SSB 1(SSB intake 0 g/d), SSB 2(0 g/d < SSB intake < 50th percentile) and SSB 3(SSB intake ≥ 50th percentile). Result of daily intake of SSB was 76.1±6.2 g/d for boys and 59.5±4.7 g/d for girls and it was increased significantly for boys(p-trend 0.0004) and girls(p-trend 0.0038) by year. The most intakes were carbonated drinks followed by fruit juices and sports drinks for boys and girls. Percentage of daily intake compared to the dietary reference was increased for energy and iron while was decreased for calcium and vitamin C toward SSB 3 group. Ratio of excess intake of energy/fat was increased significantly for boys(p=0.0091) and girls(p<0.0001) toward SSB 3 group. Ratio of calcium deficiency was 86.8~94.9% for boys and girls and it was very high. Therefore, it should be emphasized to reduce SSB intake and drink plain water without added sugar, etc. and milk as a source of calcium for improving nutritional status of middle school students through dietary education and social support.
