Women have a greater incidence of coronary heart disease(CHD) after menopause. It relates to hormone imbalance-induced changes in known CHD risk factors, especially hyperlipidemia. Accordingly, once women are diagnosed, the rate of morbidity and mortality is greater than for men. Thus, preventive strategies are critical to improve the quality oflife in the later years for women. The purpose of ths study was to explore the difference of anthropometric, environmental factors and food behaviors between normocholesterolemia and hypercholesterolemia within postmenopausal women. The subjects were classified as normocholesterolemia and hypercholesterolemia based on the Guideline for Korean Hyperlipidemia. The results obtained are summarized as follows. The distributions of general characteristics such as age, family income, occupation status, age at menarche, and menopausal period were not significantly different between the normocholesterolemia group and hypercholesterolemia group. The anthropometric factors such as body mass index(BMI) and waist hip ratio(WHR) were not significantly different between the normocholesteroemia group and the hypercholesterolemia group but odds ratio of hypercholesterolemia group was higher than that of normocholesterolemia but not significant. Aerobic activity more than 1hours/day was significantly related to low serum cholesterol concentration. Eating behaviors related to regular meal time, regular breakfast habit, and slow meal speed were related to low serum cholesterol concentration. Eating the chicken without skin was significantly related to low serum cholesterol concentration. Our data indicate that desirable eating habit, aerobic activity more than 1hr/day are important factors of serum cholesterol concentrations in postmenopausal women. The result of this study provide information that is important in designing appropriate dietary guidelines for hypercholesterolemia in postmenopausal women.

This study was conducted to investigate the relationship among dietary behavior, meal balance, and clinical symptoms related nutritional status and Attention Deficit Hyperactivity Disorder(ADHD) in preschool children. The survey was conducted using questionnaires and the subjects were 3~6 years old preschool children in Samcheok. Subjects were divided into an ADHD dispositions group(n=88) and a normal group(n=129) based on assessments conducted by the children's mother using the Abbreviated Conners's Parent Rating Scale. There was no significant difference in meal frequency, meal speed, meal regularity or meal balance between children with ADHD dispositions and the normal groups. The ADHD disposition group had a higher proportion of children with picky eating(p<0.05), too much snacking(p<0.05) and over eating (p=0.05) habits than the normal group. In addition, the ADHD dispositions group had a higher frequency of clinical symptoms such as 'breathlessness when going up stairs', 'sleeplessness', 'anxiety' and 'tiredness'. Overall, there was a significant relationship between ADHD disposition and dietary problems and clinical symptoms related to poor nutritional status in preschool children. Therefore, to prevent and treat ADHD in preschool children, proper dietary management such as correcting of picky eating, over snacking and overeating is needed.

The purpose of this experiment was to study the feeding behavior and running speed under various feed deprivation lengths and social environments. Three trials were conducted. Trial 1: ten pigs were trained individually to run a course and eat their feed at the end of the course. The pigs were deprived feed for 1, 5, 10 or 20 h. Trial 2: 1. Two pigs ran and ate together. Both pigs had 5 h of feed deprivation before the run (D5). 2. Two pigs ran and ate alone, but both pigs had 5 h of feed deprivation before the run (S5). 3. Two pigs ran and ate together. Both had 1 h of feed deprivation before the run (D1). 4. Two pigs ran and ate alone and both pigs had 1 h of feed deprivation before the run (S1). 5. Two pigs ran together, one had 5 h of feed deprivation, and the other had 1 h of feed deprivation before the run (51). Trial 3: 1. On the 1st day 5 pairs of pigs had 5 h feed deprivation and could eat feed together at (B) point (D1). 2. On the 2nd day the pigs ran and ate alone at (B) point after 5 h of feed deprivation. Feed was obtainable (D2). On the 3rd to 6th days, the pigs ran in pairs after 5 h of feed deprivation and only the dominant pig ate feed at point (B). The inferior pig was chased back to room and fed there. This stage was continued for four consecutive days, d 3 to 6. In trial 1, the running speed of pigs increased with the length of feed deprivation until 10 h, then being stable afterwards. Total feeding time increased with the length of feed deprivation (p<0.001). Eating speed did not increase with the length of feed deprivation (p>0.05). In trial 2, nine of ten pigs in treatment D5 ran faster than those in S5. Seven of the ten pigs in treatment S1 ran faster than those in treatment D1. The pigs in treatment D5 had significantly higher feed intake (p<0.001) and eating speed (p<0.05) than the pigs in other treatments. In trial 3, there were significant differences on running speed between D1 and D6 (p<0.01) and between D2 and D1, D3, D4 and D5. The inferior pig ran faster in D2 but from 3 to 6 it was the dominant pig that showed the greatest speed in completing the whole course. The results demonstrated that the pigs with low feeding motivation may cause low running speed to feed and low feed intake of the neighbor when compared with pigs kept individually.

The purpose of this study was to find out the dietary attitudes and behaviors, intake frequencies of food groups, health-related opinions and practices, and sociodemographic characteristics of housewives in Wonju-Gun rural area. Interviewers asked 413 housewives about obove informations and then recorded. The results were as followes : Using the factor analysis processing, 17 questions about dietary attitudes and behaviors were categorized into 5 groups such as fidelity of diet, the healthful dietary attitudes, the eating practices concerning about items and amount, eating speed and the extent of coincidence in food preference within a family. The role of the housewives was a major factor affecting the dietary attitudes and behaviors. Those who work as housewives and farmers concurrently had good dietary practices concerning about items and amount, but they were interested about health-directed dietary attitudes at a significantly lower level. Food frequencies of 9 groups, animal protein food, fruits and vegetables, milk and milk products, small fishes such as anchovy, soybean curd and beans, seaweeds, vegetable oil, frying food, soybean paste were significantly associated with subjects' age, role, and education and income level. Whether or not intake of soybean paste was considered. protein food intake was altered, and the difference between two situations increased much more as age was higher. We noticed that intake of soybean paste improved the status of protein nutrition. Our subjects ate calcium sources and dishes using vegetable oil insufficiently. Those who had much interests for good health, revealed to be an active practitioner in the aspects of healthful dietary attitudes, but fidelity of diet, eating practices concerning about items and amount showed significant association with balanced life style.

The principal objective of this study was to identify the dietary and physical activity patterns of obese preschoolers, and to determine the association between child obesity and mother's' dietary habits or thoughts regarding dieting/weight. This is a cross-sectional, community based study, and 305 preschoolers who attended kindergarten in Seoul and its surrounding area were selected. The measurements of dietary habits both in preschoolers and their mothers, physical activities of preschoolers, and daily servings of foods were based on parents' self report. Weight and height were used to calculate WLI (weight length index) in preschoolers and BMI (body mass index) in their mothers. The subjects were divided into two groups 245 normal weight preschoolers (including underweight 15.1% and normal weight 65.6%) and 59 obese subjects (overweight 14.4% and obese 4.9%). With regard to dietary habits in normal and obese preschoolers, we noted significant differences in 5 questions, such as mostly eating heavy meals, one serving size, eating speed, overeating, and obsession about eating. No differences in daily servings of major foods and snacks, except fruits and potatoes, were noted between normal and obese children. Among 13 questions regarding mothers' dietary habits, only 3 questions-"preferred to instant foods", "finish meals within 15 minutes", "use nutritional information for selecting foods" were significantly different between normal and obese subjects. The total scores of mothers' dietary habits was significantly and negatively correlated with number of mother's dieting experiences or mother's BMI, but was not correlated with preschooler's obesity.
