Several nutrients are known to affect bone mineral density (BMD). However, these nutrients are combined with food intake and dietary patterns and little is known about the association of dietary patterns and BMD. The objective of this study was to investigate the association of dietary patterns with BMD in Korea Genome Epidemiology Study subjects. Among 2,884 women (40-69 yr) recruited at baseline study (2001), 861 subjects with BMD measurements at baseline and a 4-year follow up study (2005) completed the semi-quantitative food frequency questionnaire. BMD was measured by the Quantitative Ultrasound method. One hundred three food items were combined into 17 food groups and 4 dietary patterns were identified by factor analysis. Cluster analysis using factor score classified each subject into one of three dietary pattern groups named 'Rice and kimchi eating' (n = 617), 'Contented eating' (n = 124), and 'Healthy and light eating' (n = 120). The 'Healthy and light eating' group, characterized by higher intake of fruit, vegetables, fish, milk and dairy products, and younger age, more exercise, higher education, and higher income than other groups. The tibia BMD of the 'Healthy and light eating' group was higher than the other groups after adjusting for the age. After the adjustment for the age BMI and exercise, the 'Healthy and light eating' group showed significantly lower odds of tibia osteopenia/osteoporosis risk compared to the 'Rice and kimchi eating' group both at the baseline [OR(95% CI) : 0.50(0.30-0.84)] and follow-up [OR(95% CI) : 0.59(0.36-0.97)] examinations. The dietary pattern with low calorie and high intakes of fruit, vegetables, fish, milk and dairy products may have beneficial effects on BMD in middle-aged women.

Objectives: The purpose of this study was to estimate the distribution and exposure prevalence of total carbohydrate intake and the carbohydrate-based foods such as rice, noodles, sweet potatoes, sweet drinks, milk and fruits and to characterize intake patterns among obese Korean adults. Methods: Subjects included 137,363 adults aged 40 years or older who participated in a Health Examinees (HEXA) Study. Multiple regression analysis of data from Semi-Quantitative Food Frequency Questionnaire (SQFFQ) identified food sources of carbohydrates. Weight, height and waist circumstance (WC) were measured, and the body mass index (BMI) was calculated. Obesity was defined as $BMI{\geq}25kg/m^2$ and abdominal obesity as $WC{\geq}90cm$ and ${\geq}85cm$ for males and females, respectively. Results: Obese adults appeared to have a higher total carbohydrate intake in the univariate analysis but had eaten less after adjustment for general and lifestyle factors, compared to normal weight adults (OR 0.78, 95% CI 0.73-0.82 for general obesity; OR 0.79, 95% CI 0.74-0.85, for abdominal obesity; P trend < 0.0001, respectively). Based on advance analysis for the food sources of carbohydrates, obese subjects had lower intake of rice (OR 0.86, 95% CI 0.68 -1.09 for general obesity; OR 0.87, 95% CI 0.67-1.13, for abdominal obesity; P trend < 0.0001, respectively) and higher intake of noodles (OR 1.21, 95% CI 1.16-1.27 for general obesity; OR 1.25, 95% CI 1.19-1.32, for abdominal obesity; P trend < 0.0001 respectively). With regard to other food sources of carbohydrates such as milk and fruits, intake was lower among obese compared to normal weight subjects. Conclusions: In the Korean middle-aged and older obesity groups, the intake of carbohydrates and the related foods was lower than in normal weight subjects, except for noodles. We conclude that a higher intake of noodles may enhance weight-gain. Therefore, this study suggested that the guidelines should consider the types of carbohydrate sources and the amount consumed from foods in order to provide proper guidance with regard to control and prevent obesity among Korean adults.

To assess the quality of nutrient intake by area of Korean adults, a dietary survey with the 3-day record method was obtained from 324 subjects aged 40 years and older but younger than 70 (52.4 $\pm$ 8.7) living in a rural area (Ansung) and suburban area of a middle-sized city (Ansan). The quality of nutrient intake was assessed by analyzing Nutrient Adequacy Ratio (NAR), Mean Adequacy Ratio (MAR) and Index of Nutritional Quality (INQ). The average daily mean energy intakes were 1,832 ㎉ for Ansung and 1,842 ㎉ for Ansan, respectively. Daily intakes of fat for Ansung and Ansan subjects were 40.9 and 40.3 g, and those for protein were 75.1 and 73.1 g, respectively. The overall calorie: protein: fat ratio (CPF) of energy intake was 63 : 17 : 20. Daily mean intakes of protein, fat, calcium, phosphorus, iron, potassium, carotene, sodium, thiamin, and niacin were significantly higher in Ansung residents than in Ansan subjects (p < .05). The average intakes of energy, calcium, vitamin A were lower than Recommend Dietary Allowance (RDA) in both areas. Note, over 30% of the study subjects had less than 75% of RDA of calcium, vitamin A and riboflavin. The MAR was higher in Ansung than Ansan residents (0.86 and 0.85, respectively; p < .05). INQs were over 1 for most nutrients except calcium (0.87), and that of calcium and phosphorus was each significantly higher in Ansung than Ansan subjects. Based on these results, nutrient intake quality of subjects aged 40 to 69 years living in the surveyed rural area is comparable to that of semi-industrialized suburban area in Korea. Dietary deficiency in all of calcium, vitamin A, and riboflavin, however, was a common problem for both rural and suburban residents.

Purpose: To evaluate safety, gastrointestinal tolerance, and growth of a new experimental starter formula (NESF) fortified with lutein, prebiotics, probiotics, nucleotides and beta-carotene, fed to infants within the first months of life. Methods: This was a non-randomized, open, uncontrolled study conducted from December 2010 to May 2011. Twenty-three healthy infants aged 10 days to 2 months old were enrolled. Outcomes included gastrointestinal tolerance, physical growth and safety. Prior to the initiation of the trial, the Scientific Research Institute of Nutrition of the Russian Academy of Medical Sciences confirmed that the NESF met all safety and nutritional parameters. Results: NESF was well tolerated. The majority of infants fed this formula passed semi-liquid, yellow or yellow-brown. The mean stool frequency/day was $2.5{\pm}0.4$ on study-day 14 and $1.8{\pm}0.5$ on study-day 28. The mean daily weight gain was $30.9{\pm}3.8$ grams and the mean length gain during the 28 days of follow up was $3.1{\pm}0.8cm$, corresponding to the average physical growth normally seen in the first months of life in Russian infants. Six children left the study: one refused to drink the formula, one left the study as parents changed residence; and one child's parents have recalled their informed consent due to adverse event unrelated to the product. Three infants presented adverse events possibly related to the product (rash; colic and abdominal pain; constipation). Seventeen infants completed the trial. Conclusion: This study demonstrated that lutein-fortified formula is safe, well-tolerated and supported physical growth of evaluated infants.

In Kenya, traditional knowledge on herbal medicine has remained a mainstream source of maintaining wellbeing for generations in many communities. However, the knowledge has been eroded in the course of time due to sociocultural dynamics virtually advanced by Christianity and formal education especially in the Kikuyu community. The study documented current ethnobotanical knowledge and threat to the traditional knowledge on medicinal plants among the Kikuyu community. A survey was carried out in Mathira, Tetu, Kieni, Othaya, Mukurweini, and Nyeri Town constituencies. Thirty practicing herbalists were purposively sampled; 5 per constituency. Data was obtained through semi - structured questionnaires and analyzed both qualitatively and quantitatively. A total of 80 ailments treated using 111 medicinal plant species distributed within 98 genera and 56 families were documented. Prevalent communicable diseases treated using herbal medicine included; gonorrhea (17.5%), malaria (15%), respiratory infections (12%), colds (10%) and amoebiasis (10%). Non-communicable diseases were; joint pains (11.1%), ulcers/hyperacidity (8.7%), high blood pressure (8.7%), intestinal worms (11.1%) and arthritis/gout (10%). Frequently harvested plant materials were; roots, barks and leaves. The study concluded that, traditional medicine practitioners in Nyeri County possessed wide knowledge of herbal medicine but this knowledge was on the verge of disappearing as it was largely a preserve of the aged generation. The study recommended massive campaign about the benefits of using herbal medicine in the study area. Further pharmacological studies are recommended on the mentioned plant species aimed at establishing their efficacy and safety as well as standardization as potential drugs.

To discern general tendency in relatively pure even-aged pine stands, to group the stands and to perceive neighbourhood effects a total of 39 sites of pine stand was surveyed from nearby Seoul (12 sites), Chunsung, Kangwon (13 sites) and Sosan, Chungnam (14 sites), for herb and shrub species 32, 19; 37, 19 and 41, 14 in the respective areas from September 1987 to July 1988. In terms of detrended correspondence analysis (DECORANA), the stands were subjected to ordinate with 16 physical variables and the vegetational variables. The resource ratio (N:P, N:K, P:K) as physical variables also was tried out in the DECORANA as well as independent variable (N.P.K). The outcome did not show any meaningful difference. It is suggested that there seems to be no apparent interaction among the elements in the study. Three vertical vegetation componeent, that is, tree layer, shrub layer, herb layer were subjccted to DECORANA independently, pairwisely and as a whole (a total 7 combinations). Of those analysis herb layer trial alone seems to indicate relatively clearer differences among the physical variables. In the stands nearby Seoul first axis indicated soil field capacity and exchangeable cations (K, Ca and Na) and second axis did not show any tendency. For the Chunsung stands first axis also revealed soil field capcity and amount of arganic matter and second axis showed amount of exchangeable cation (K, Ca and Na), In the Seosan 1st axis indicated pH and exchangeable cations (K, Ca and Na). For the 39 sites 4 clusters in terms of herb layer might be defined: Peucedanum terebinthaceum-Cymbopogon tortilis-Polygala japonica-Festuca ovina (1); Atractylodes japonica-Patrina scabiosaefolia (2); Potentilla fragarioides-Atractylodes (3); and Cymbopogon tortilis (4). In the neighbourhood effects study in terms of the basal area distribution, Thiessen polygon area and Gini coefficient for the Pinus thunbergii stands of Seosan the Thiessen polygon area approach seems to indicate earlier (30 years old) neighbourhood effect than the others (45 years).

This study was conducted to find out the purchasing characteristics, the wearing practices and the preferring style of skirts. Also the comparison between recognized body type and actual body type for skirt was analyzed. The questionnaire was developed and administered to 179 women aged 20 to 59 in Busan. The women of 20th liked to buy skirts at the road shops and the internet shops but the 30th, 40th and 50th at the department stores and the discount stores. The main purpose of buying skirts was to coordinate with other clothes. The design of skirt was the most important factor of buying. The women of the 20th wore skirts without special purpose but the 30th, 40th and 50th wore those for social life. The women of the 20th liked to wear skirts with t-shirts and cardigan, the 30th with blouse and cardigan and 40~50th with blouse and jacket. As the age increased, the ratio of women who felt discomfort of skirts increased. Most of these women felt discomforts in the waist and abdomen part of skirt. The style of skirt that made up for the weak points in the body type was preferred. The preferred silhouettes of skirts were semi-tight and A-line. The preferred lengths of skirts were different from ages. Black was preferred color of skirts. There was a significant difference in recognized body type according to age groups. As the age increased, the ratio of women who thought themselves as thick waist type increased. Just only 43% women of total subjects recognized their body type accurately.

With a continuous and steep increase in life expectancies, Korean society is expected to enter the aged society by year 2020. And as the number of elderly increases, the burden of medical and health care expenses for them becomes greater in every developed society. Hence, the preventive approach for chronic degenerative diseases remains to be the best solution for the above-mentioned problem and warranting optimal nutrition would be one of the most important approaches. We performed a nutrition survey on 585 older adults of 50 years of age and older, residing in 3 metropolitan areas including Daejun, Daeku and Kwangju. Anthropometry, including body composition analysis based on the bioelectrical impedance analysis using InBody 3.0 and dietary intake survey by semi-quantitative flood frequency questionnaires, were used in collecting data. As one of the most important factors affecting the health and nutritional status of the elderly, we focused on living arrangements. Analyses were performed on the data from 550 subjects only, after excluding statistical outliers. Three hundred and sixty-eight of them(66.9%) were female and the number of elderly(65 years of age and older) was 485. According to the statistical analyses, the female elderly were more vulnerable to malnutrition than the male elderly. And the older they befame, the less adequate they were in nutrient intake. In addition to this, the elderly living alone showed the poorest patterns of nutrient intake and anthropometry. Although the exact effect of living alone could differ among different sex-age groups, the fact that the elderly living alone is vulnerable to malnutrition would remain concrete. This raises the utmost necessity of nutrition intervention to be devised and directed to the targeted population, namely the living-alone elderly from the government level. The intervention may include nutrition education, nutrition counseling and support In forms of meal service by networking the efforts of central as well as local governments to ensure the good health of the Korean elderly.
