This study was carried out to evaluate meal management behavior of housewives and to improve their behavior by determining what problems exist. The survey was conducted using a questionnaire in Jinju from October to November in 1999. It was shown that 29.1% of housewives didn't plan food budget, whereas only 5.6% of them did. The reasons for not planning food budget were mostly due to not forming a habit(38.8%), irregularity of prices(19.9%) or irregularity of income(13.8%). The characters of planning food budget and the reasons for not planning were not affected by age, education, monthly income, family size or monthly flood cost. Only 17.8% of meal managers recorded their housekeeping in detail and 47.4% of them wrote only the important things. Recording housekeeping records was affected by age and education. It was found that most meal managers(90.8%) didn't set menu planning and they didn't fuel the need for menu planning. The frequency of food shopping was every two days(36.2%), twice a week(20.9%) or randomly(27.4%), and the places for food shopping were supermarket(49.0%) and traditional market(41.3%). Both were affected by education or age. The quality of food was the main reason(54.6%) far the selection of food shopping place. Important consideration for selection of food and meals was preference of family(47.4%) and this character was affected by education. It was shown that the score of nutrition knowledge was 7.36, and it was affected by education. The results of this study suggest that the government, educators and scientists in nutrition make efforts to develop various levels of practical education programs for meal management and nutrition depending on age, education and community using mass media.

This study was intended to collect the baseline information on dietary behavior of adults to develop nutrition education program in the context of health promotion at community level. Nutrients intake of 135 housewives were assessed by 24 hour recall methods. Also food habits, nutrition knowledge and attitude were investigated by self-administered questionnaires. Our results indicated dietary intake of calcium and vitamin $B_2$ were insufficient when they were compared to Korean recommended dietary allowances(RDA). Among five food groups, intakes of milk and dairy product was inadequate as compared to the recommended amount. When we compared the fatness indices to self-evaluated meal problems, overeating and speedy eating were significantly related to fatness indices. Fatness indices such as relative body weight(RBW) and body mass index(BMI) were significantly higher in the subjects who self-evaluated their unsound food behavior as overeating. However, there were no significant differences of food habit score and nutrition knowledge among groups classified by fatness or meal problem. Body fat ratio, frequencies of night snack and skipping meal significantly increased with age. Food habit score was positively related to health-concerned attitude and active attitude toward change. We concluded that nutrition education program for housewives should include detailed strategies to modify unsound food behaviors for healthy weight.

This study was conducted to provide basic data for product development and marketing strategies for the Thai home meal replacement (HMR) market, to reflect the changing trends in household sizes in Thailand. The results of analyzing the characteristics and differences of HMR consumption behavior between single-person households and multi-person households in Thailand were as follows: It was found that single-person households use HMR to save money and for the convenience in cooking and preparation. In the preference by HMR type, multi-person households showed a higher preference for all types of products than single-person households. Thai consumers, regardless of their household size, mainly use department stores and large shopping malls to purchase HMR, and they most prefer to get information through Internet advertisements. The shelf life, quality, taste, hygiene, and freshness of HMR were the main considerations for their selection. Based on the results of this study, the Thai market requires the development of HMR products that are reasonable in terms of cost and preparation time. In addition, it is necessary to develop products that can satisfy consumer needs, such as nutritional enhancement and therapeutic foods, products that are organic, eco-friendly, cater to various menus, and address the premium segment.

BACKGROUND/OBJECTIVES: While many obesity studies have pointed out the importance of meal regularity, few have conducted empirical analyses using data from food diaries. We examined the association between meal regularity (i.e., meal time regularity [MTR] and calorie intake regularity [CIR]) and weight loss. SUBJECTS/METHODS: We collected food diary data from 637 women who had participated in commercial weight loss programs for 28-168 days (4-24 weeks). This study defined "meal regularity" in terms of two concepts: MTR and CIR. MTR refers to how regularly people eat their meals (i.e., at certain times each day), whereas CIR refers to how regularly people consume a certain amount of calories at each meal. We conducted multiple regression analyses. RESULTS: MTR (model 1: β = -2,576.526, P < 0.001; model 2: β = -1511.447, P < 0.05; model 3: β = -1,721.428, P < 0.05) and CIR (model 1: β = -1,231.551, P < 0.01; model 2: β = -2,082.353, P < 0.001; model 3: β = -1,343.490, P < 0.01) turned out to be significant determinants of the amount of weight loss in breakfast, lunch, and dinner contexts. While meal regularity (i.e., MTR and CIR) was significantly associated with weight loss, daily calorie intake from meals was not significantly associated with the amount of weight loss (model 1: β = 0.13, P > 0.05; model 2: β = 0.11, P > 0.05; model 3: β = 0.14, P > 0.05). Subjects who consumed an equal amount of calories per meal throughout the day lost more weight than those who did not (model 4: β = -3,675.51, P < 0.001). CONCLUSIONS: Eating each meal (i.e., breakfast, lunch, and dinner) at a certain time every day may increase weight loss success. Also, consuming the same amount of calories at each meal may help weight loss success.

The purpose of this study was to determine the influences on physical status and study achievement by the dietary behavior of the youth in Korea. The survey was carried from June to July, 1995 by way of questionnaire to 397 students. The students' study achievement records and physical status were analyzed by the factor of dietary behavior. The results were as follows: 1 The average physical status of male students was lean, but females were standard. 76ft of mothers of the subjects were working in specialty farming. The monthly income of their family was $1000{\sim}1500$ thousand Won and students' pocket money was $20{\sim}40$ thousand Won per month. 2. The aspects of meal behavior included the general idea that the meal was thought to relieve hunger, and preference of taste was spiciness The most important factor of the meals for the students was taste. Their bad meal habits were quick eating and irregularity of meals. 3. There was a significant difference in the comparison of the study achieving records with the frequency of supper However, there was no one meaningful difference between study achievement records and the attendance rate to school, health status, and living conditions. However, there was a significant difference between their study records and eating with family. The students, who had the breakfast and/or supper with family, remarked better study records than other groups. 4. Also, there was a significant difference of study records with physical status. The overweight or obese students had a lower degree of study score (p<0.1). Adolescence is considered a period of setting up dietary behavior, so it is necessary to educate good nutrition and dietary habits for students to keep in healthy physical condition and with high study achievements.
