본 연구는 비만아동을 위한 효과적인 운동 및 식이 요법에 관한 자료를 얻기 위하여 실시하였다. 대상자는 8~12세의 비만아동(체지방 $36.1\pm1.3%)과$ $정상아동(18.9\pm1.3%)$ 각각 5명이었으며 3일간 실험환경에 적응하기 위한 대조기간(Control : C)을 거친후 1주간은 운동은 부하하되 에너지는 제한하지 않는 운동기간(Exercise without energy deficit : EEN)와 다음 1주간은 비만아동만을 대상으로 운동부하와 동시에 에너지를 제한하는 에너지 제한 운동기간(Exercise with energy deficit : EED)으로 나누어 실시하였다. 운동강도는 60~75%HRmax이었으며 에너지 제한량은 493kcal/day이었다. 각 실험 조건별 대사에너지 섭취량, 체중, 체성분, 체내 보유 에너지, 에너지 소비량의 변화를 측정하였다. 체지방량은 생체 전기저항 지방측정기를 이용하여 측정하였다. 대변 및 소변으로의 에너지 손실량으로부터 측정한 1일 평균 대사 에너지량(ME)은 정상아동이 대조기간(C) 및 운동기간(EEN)별로 각각 $1802\pm50kcal$ 및 $1771\pm72kcal이었고$ 비만아동이 대조기간(C) 및 운동기간(EEN) 및 에너지 제한 운동기간(EED)별로 각각 $2152\pm138kcal,$ $1861\pm138kcal$ 및 $1368\pm87kcal이었다.$ 대조기간(C)에 비만 아동은 정상아동에 비해 대사에너지량(ME)이 높았으나 무지방조직(LBM) kg당 섭취량은 정상아동이 79kcal이며 비만아동이 70kcal로 오히려 비만아동의 경우가 낮았다. 대체로 운동에 의해 에너지 섭취량은 감소되었다. 동일한 운동 부하로 정상아동 및 비만아동의 체중은 각각 $1.00\pm0.20kg$ 및 $1.24\pm0.22kg씩$ 감소되어 정상아동에 비하여 비만아동의 체중감소가 더 많았다. 비만아동에서 에너지 제한(493kcal)으로 인한 체중감소량은 0.52kg이었고 체지방조직량(FM)은 0.46kg이었다. 운동기간(EEN)중 체성분 변동량으로부터 산출한 1일 1인당 체내 에너지 변동량은 정상아동이 1092kcal, 비만아동이 1270kcal 감소디어 비만아동의 에너지 소모량이 더 많았다. 비만아동에 있어 에너지제한 운동기간(EEN)에 정상아동이 $2863\pm58kcal,$ 비만아동이 $3131\pm158kcal이었으며,$ 에너지 제한 운동기간(EED)에 비만아동은 $3153\pm151kcal이었다.$ 이상의 성적으로 보아 본 실험에 적용한 운동 프로그램은 체중 감소에 효과적으로 작용하나 일부 부지방조직(LBM)의 감소를 동반하는 것으로 보아 다소 운동 부하량이 과도한 것으로 생각된다. 그러나 에너지 제한량(500kcal)은 체중감소에 매우 효율적인 것으로 평가되어 이후 비만아동의 체중조절에 본 실험의 에너지제한 운동 프로그램중 운동 부하량만을 다소 줄여 적용하면 매우 효과적일 것이라 생각된다.

This study was conducted to identify the BMI of enlisted soldiers, to understand the difference between their BMI and that of other men in their age group, and to identify the influence factors of enlisted soldiers' BMI change. The survey has been conducted self-evaluation questionnaire from 23 Feb. 2009 to 31 Mar. 2009 from 4 different forces as methods. Independent-sample T-test, chi-square test and multiple linear regression analysis were used for statistical analysis from 301 collected data. As a result of surveying enlisted soldiers' BMI, their obesity rate 18.6% was lower than 22.1% of other men in their age group. In terms of health behavior, the underweight&normal weight group(2.39) showed higher diet score than the overweight group(2.13), showing that the underweight&normal weight group ate relatively slowly, less spicy and less sweet food compared to the overweight group. The overweight group(2.25) showed lower satisfaction with their body type than the underweight&normal weight group(2.98), while the overweight group(4.01) showed a significantly higher score than the underweight&normal weight group(3.37) for weight control activity. The influence factors of BMI change were diet habit, subjective perception of body type, and weight control activity. In order to improve of enlisted soldiers' BMI, it would be necessary to improve the food service and the snack bars for interventional control of food that influence obesity, rather than personal effort, in addition, education for right body-shape perception and encouraging on weight control activity.

This study was carried out to investigate nutrient intake, dietary self-efficacy, and physical activity self-efficacy of elementary school students by obesity index in Gyeongbuk area. The survey was conducted from June 7 to June 18 in 2005. The study was peformed by analyzing a questionnaire answered by 523 elementary school student in 5th and 6th grade. The obesity index was gained by height and weight data. Nutrient intakes was evaluated by 24hr-dietary record. Statistical data analysis were completed using the SPSS 12.0 program. The results were summarized as follows; The result of the body measurement was that 31.7% of underweight group, 45.1% of normal group, 12.8% of overweight group, 10.3% of obese group. 13.9% of underweight group experienced weight control, and 17.5% of the subject respond they will try the weight control in the future. Male students showed significantly higher exercise frequency than female students(p<0.001). Male underweight group and female obese group show the highest exercise frequency. Daily energy intake of the subject showed 80.1% in male students and 87.5% in female students revealed under the recommended dietary allowance(RDA) for Korean. The intake ratio of energy nutrients was identical in male and female of underweight group and obese group, so this showed that intake style was similar in two groups. By investigating through MAR(mean adequacy ratio), underweight group of male students and both normal and overweight group of female students were lowest, while overweight group of male students and underweight group of female students were the highest. Physical activity self-efficacy of male students was higher than female students, and physical activity self-efficacy by obesity index was higher in underweight group of male students and obese group in female.

In our previous work, we reported consumers' perceptions of body shape and weight control. In an ongoing effort, we analyzed the purchasing behavior, intake patterns, future purchasing decisions, and degree of satisfaction in individuals consuming dietary formula for weight control (DF) or heath/functional foods (HFFs) by using the same survey questions. Portfolio analysis for marketing strategy was also investigated. Subjects were divided into two groups according to consumption of DF or HFF during the previous year : DF group (n = 89) and HFF group (n = 110). Average intake frequency was $1.7{\pm}0.7$ per day for HFFs and $1.5{\pm}0.9$ per day for the DF, and the most prevalent form was pill (58.2%) for HFFs and bar (42.7%) for DF. Duration of intake was $3.1{\pm}2.3$ months for HFFs versus $3.9{\pm}3.5$ months for DF. The average degree of satisfaction was $3.6{\pm}0.6$ on a 5-point scale, meaning 'relatively satisfied'. For the weight control method to be used in the future, 44.5% of the HFF group selected 'HFFs' while 47.2% of the DF group selected 'DF', showing a tendency to use the current product type in the future. The average planned period for the intake was $3.8{\pm}3.7$ months for HFFs and $3.0{\pm}2.4$ months for DF (p < 0.05). The HFF group emphasized efficacy, functional ingredients of the products, reliable products, and higher satisfaction, whereas the DF group emphasized the added materials in addition to weight control effects.

The seven (7) housewives were used as subjects at three times per weeks for twelve (12) weeks in order to find out the effects of aerobic exercise and weight training on body composition and blood lipid. Each subject's weight, lean body mass, percent body fat, BMI and blood lipid were measured immediately after the training and the results compared with the same prior to exercises were obtained as follows ; 1. The weight and percent body fat of the subjects were slightly but not significantly decreased, however the lean body mass following training was significantly increased with 1.3 %. BMI S RBW were also not significantly decreased. 2. Calory intake was 1929.9 cal before the training and 1896.0 cal after the training, which doesn't shows much difference. 3. The blood lipid such as TC and LDL-C were a little increased after the training, but HDL-C shows significant increase of 22.7 %, and HDL-C/TC was significantly increased with 13.2 % (p<.05 ) as well. However, TG shows significant decrease (p<.05 ).

This study was conducted to identify factors influencing weight loss efforts in hypertensive patients with obesity in Korea using data from the 2016-2019 National Health and Nutrition Examination Survey. Weight perception, weight loss efforts, and weight control methods were investigated for 1,910 subjects. Data were analyzed using descriptive analysis, cross-tabulation analysis and logistic regression. Among obese hypertensive patients, 12.6% perceived their weight as normal. Weight loss efforts were 2.03 times (95% CI: 1.48 to 2.78) higher in people with overweight perception than those with normal weight perception, and 1.74 times (95% CI: 1.33 to 2.26) higher in women than in men. In addition, those with class 1 obesity were 1.50 times (95% CI: 0.85 to 2.65) higher than those with class 3 obesity, and those with class 2 obesity were 2.16 times (95% CI: 1.16 to 4.00) higher than those with class 3 obesity. These results suggest that weight management approaches for hypertensive patients with obesity should be individually designed according to weight perception, gender, and obesity class.

This study was carried out to obtain information related to life styles, nutrition knowledge, and dietary habits according to gender and weight status of college students in Ulsan. The subjects were 324 college students (144 males, 180 females), and they were divided into three groups based on BMI. The average BMI was $21.0kg/m^2$, and the BMI of underweight, normal, and overweight students were 15.4%, 63.0%, and 21.6%, respectively. Among the male students, 0.1% and 34.0%, and among the female subjects, 27.2% and 11.7%, were included in the underweight and overweight groups, respectively. For dietary habits, the rate of skipping breakfast (34.9%) was considerably higher than those skipping lunch and dinner. Overall, the nutrition knowledge score, which was assessed by 15 questions, was somewhat low (44.9/100), yet, it was higher in females than in male students. There were significant differences among gender and weight status in several items of dietary habits such as the speed of eating meals, consuming breakfast on a regular basis, and sleeping hours. 40% of the subjects had appropriate knowledge about high calorie foods with low nutritional value. In the blood analysis of the subjects, males had higher hemoglobin levels than females. Further, more females were included in the risk group of Hb, total cholesterol, and LDL. These results suggest that in order to develop nutrition education programs for college students, differences between gender and weight status, dietary habits, and nutrition knowledge level should be considered.

The purpose of this study was to investigate the general characteristics, body shape, and perceptions of weight control in individuals consuming functional health foods and weight-control foods. The survey was conducted between April 15 and June 17, 2010 among 199 (57 males and 142 females; age range, 25-45 years) in Seoul and Gyeonggi-do, who experienced eating functional health foods or weight control foods during the past year (June 2009 to June 2010). The subjects were divided into a weight-control food group (89 adults) and a functional health food group (110 adults). The subjects were comprised of a high proportion of aged (average age, $34.2{\pm}5.9$ years), graduates (71.9%), and married (65.8%) individuals. In the weight control food group, gender, age, and educational background were similar and the ratios of service/technical employees, college students, and normal-weight individuals [body mass index (BMI), < 23] were high. BMI was significantly different by gender (p < 0.001), age (p < 0.01), marital status (p < 0.001), and job type (p < 0.001). Self-perceived health status showed a higher response for "in good health" in the 35-44 year old group than that in the 25-34 year old group (p < 0.05). Male group satisfaction for body shape was significantly higher than that in the female group. The main reason for going on a diet was significantly different by gender (p < 0.05) and BMI (p < 0.01). The main motives for dieting were "because I am not at an ideal weight" and "because of the social atmosphere and the attention of others " in men, but "can't wear the clothes I want" in women (p < 0.01). The most preferable product type related to the two groups was significantly different by job (p < 0.001) and BMI (p < 0.05). However, no significant differences were observed for questions about body shape perception and weight control. Consumers who had different general characteristics and used diet products perceived body shape and weight control differently. Additionally, no meaningful differences were observed when the results were categorized by product type, except job and BMI, but the distribution of consumer characteristics showed different tendencies. These results can be utilized as basic data for developing new diet products to help people control their weight more scientifically and appropriately in the future.

This study looked into the obesity status, recognition of obesity, attitude towards obesity, eating and exercise habits, and lifestyles of Korean (n=101) and Japanese (n=123) female college students. All students were 21-years-of age, with an average height of 161 cm and the average weight of 54 kg. Korean female students responded that obesity complicated friendships, and hindered study and exercise. Japanese students did not express these opinions. Both Korean and Japanese students tended to over-consume their favorite food. Korean students ate breakfast about 24.8% everyday, while 48% of Japanese students did; both regularly ate dinner. Snack preference was mainly biscuits. The factor most influencing eating habits were TV advertisement for Korean students (57.4%) and parents for Japanese students (47.2%). Once-weekly exercise was done regularly by 34.7% of Korean students but only 20.3% of Japanese students. The main reason for Korean students to exercise was weight reduction (53.5%), while 78.2% did not exercise because it was tiring. Korean and Japanese students had similar life styles, although stress relief in Korean students was sought through conversations with friends and by reading books or listening to music for Japanese students.
