The purpose of this study was to investigate the difference in dietary attitudes, dietary behaviors and health-related lifestyles among Korean college students (392 males, 808 females) participating in a web class of nutrition education. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. Most female subjects with weight-control attempt had eating habit problems such as overeating and food jags. The female subjects with weight-control attempt showed significantly higher rate of skipping dinner compared to those without weight-control attempt. As for frequency of exercise, the subjects with weight-control attempt exercised more frequently compared to those without weight-control attempt. In subjects, weight-control attempt was significantly associated with exercise. Nutrient adequacy ratio and mean adequacy ratio of the subjects with weight-control attempt were significantly lower compared to those without weight-control attempt. These results suggest that skipping dinner or exercise might be used as weight-control methods in Korean college female students participating in a nutrition education class via the internet.
This study was conducted to investigate the relationship between body image and BMI with satisfaction of own body image, snack intake practices, food intake practices and weight control practices of 226 female college students in Jeonbuk province using questionnaire. The results were summarized as follows : 1. The average height, weight and BMI was 162.08cm, 52.02kg and 19.78, respectively. The average ideal body weight of the subjects was 48.92kg. Ninety percent of the subjects was dissatisfied with their body image. The degree of dissatisfaction was higher in the group who recognized themselves as fat. Most of subjects wanted to lose weight, but as the group having a recognition of thin body image significantly wanted to gain weight (p<0.001). 2. The subjects preferred fruits and juices for snack. The more subjects recognized themselves as fat, the more they restricted snack intake (p<0.05). 3. The rate of skipping meal tends to increase. The subjects did not intake balanced meals and skipped breakfast most (20.7%). The number of food groups taken at breakfast, lunch and dinner was 1.84, 2.25 and 2.55, respectively and the most variable food groups were taken at dinner(p<0.001). Dairy food group intake was low. The duration of meal time was longer in the underweight group by BMI regardless of body image recognition (p<0.05). 4. The weight controlling method was concentrated mostly on decreasing food intake. The more subjects recognized themselves as fat, the more they tried to control weight (p<0.001). Even though 59.5% of the subjects with no weight control experience had no future weight control plans, 50% of the group who recognized themselves as normal or fat did not want to control weight in the future (p<0.01). These results suggest that nutrition education programs and correction programs of food behaviors and weight control should start from focusing on the accurate recognition of body image for college female students.
Objectives: This study sought to assess the prevalence and duration of weight-control or health functional food use, associated weight-control behavior, perception, and knowledge among university students. Methods: The subjects were 442 university students in Cheonju, Korea, and data was collected by a self-administered questionnaire. Both χ2 and t-tests were conducted for categorical and mean comparisons. Results: An estimated 62.7% (female 69.0%, male 54.8%) had ever attempted weight-control. Among these, an estimated 59.2% of females and 38.9% of males had used weight-control or health functional foods with significant gender difference. The weight-control foods commonly used included chicken breast, protein powder, low-fat milk and soymilk, and meal replacement drinks, while garcinia cambogia extract and green tea extract were frequently used as health functional foods. One of 10 (10.3%) consumers of weight-control foods reported ≥ 7 months use, with less frequent long-term consumption of health functional foods (4.2%). The average degree of satisfaction was 3.24 ± 0.92 for weight-control foods and 2.72 ± 0.97 for health functional foods on a 5-point scale, meaning 'slightly satisfied' and 'slightly dissatisfied', respectively. Females or students with an experience of weight-control reported poorer perceptions of their health and body image as well as a higher need for weight control. Besides, both male and female subjects felt a high need for correct information regarding weight-control methods. Conclusions: Our results provide a better understanding of the characteristics associated with the use of weight-control or health functional foods among university students and will be useful in developing a nutrition education program by incorporating correct body image, knowledge, and practical yet desirable practices for weight control.
The purpose of this study is to compare the nutrition knowledge, dietary behavior and food frequency according to the gender and weight control attempt among middle school students in Seoul and Gyunggi-do, Korea. The subjects were divided into three groups, one with experience in attempting to lose their weight, one with experience in attempting to gain their weight and one with no experience in attempting to control their weight. Nutrition knowledge level of girls was higher than that of boys (p<0.01), but there were no significant difference according to weight control attempt. As for the scores of dietary behavior, there were no significant differences by gender but according to weight control attempt, the scores of dietary behavior of the weight loss attempt group were higher than those of the other attempt groups (p<0.01). In the food intake frequency, there were significant differences according to weight control attempt (p<0.05, p<0.01).
The study investigated the eating lifestyles of female consumers and whether they influenced weight control behavior. The findings of the study can be summarized as follows. First, the eating lifestyles of the subjects were presented four types: 'active eating life pursuit type', 'safe economical type', 'gourmet type' and 'passive negligence type'. In general, most cases were of the 'passive negligence type'. Second, weight control behavior was analyzed according to eating lifestyle. The results of the analysis indicated that the female consumers of the 'active eating life pursuit type' and 'safe economy type' had high behavior levels in each aspect of weight control attitude, subjective regulation, perceived behavior control, and behavior intention. Third, the 'gourmet type', with a strong preference for taste, and the 'passive negligence type', with fewer eating considerations in general, showed weaker attitudes towards weight control and the recognition of pressure from people around them. As such, the level of consideration for food or eating was correlated with weight control. These findings impliedy that the more active, safer, and economical women are in their general eating style, the stronger they perceive weight control issues.
The purpose of this study was to investigate the changes of food habits and anxiety level of obese children on body weight control program. The body weight control program included nutrition education, psychotherapy and exercise for weekly session during 9 months. The results from this study were as follows. A total of 27 obese children(boys 44.4%, girls 55.6%) participated in this study. The average age of children was 11.7 years, average height and weight were 141.7cm and 48.1kg respectively. $R{\ddot{o}}hrer$ index(RI) of children was significantly decreased from 167 to 163(p<0.001) and BMI was significantly decreased from 24.5 to 23.9 (p<0.01) after body weight control program. This study also found obesity index(OI) was significantly decreased from 133% to 128%(p<0.01) of 18 children after program. There was not significant difference in food habits score but frequency of overeating, and eating frequency of meats were significantly decreased(p<0.05) after body weight control program. Also depression score significantly decreased after body weight control program(p<0.001) and there was significant negative correlation(r=-0.552) between food habits and anxiety level. The factors analysis of anxiety items indicated that children had feelings more calm and sate after program(p<0.05). Therefore continuous and practical nutritional education and psychotherapy to change food habits and anxiety level are necessary to decrease child obesity. These results suggest that body weight control program including nutrition education, exercise and psychotherapy may be effective physiological and psychological body health of obese children.
A weight control program has been prescribed to investigate its effects on weight reduction of obese adults. The prescribed weight control program has been followed by 4 overweight adults and fad diets has been followed by 6 ovenveight adults for 3 to 7 months. The prescribed weight control program was basically the low calorie diet (1,500-1,800 kcal per day) and nutrition education was applied to enhance its effects. Fad diets were chosen among the fashionable diets and they were "apple diet" , "yogurt diet" and "Lee Hijae diet" Anthropometric measurements, biochemical parameters, and percent of body fat were measured after the respective period of weight control program. Body weight was significantly (p<0.01) reduced and the rate of obesity was also significantly lowered with the prescribed weight control program while the body weight and rate of obesity were not changed with the fad diets. Weight loss from the prescribed weight control program also led to the change of total cholesterol levels while LDL-cholesterol, HDL-cholesterol, triglyceride were not significantly changed. Nutrition education and counseling of the weight control subjects induced more weight loss and better food behavior. It is suggested that a weight loss program should be based on the low calorie diet with the well-planned nutrition education The fashionable diets were attractive for a short time period in weight reduction but the rapid weight gain was noticed right after the diets ceased.
This study was conducted to investigate the effects of weight control programs on BMI, serum profiles, nutrition knowledge and eating behaviors of adult obese women. The subjects of this study were 33 adult obese women aged 30-65 years residing in Seoul. The weight control program for obese women included nutritional education, cognitive behavioral therapy and exercise for 12 weeks. The weight control experience of the subjects was 60.6%. They preferred physical exercise and diet restriction to weight control and 72.7% of subjects answered that the reasons for wanting to control their weight was health. The BMI of test subjects significantly decreased (p<0.001) from 28.3 to 27.1 after the 12 weeks of the weight control program. In addition, the % body fat significantly decreased (p<0.001) from 36.4% to 34.5% after completion of the weight control program. SGPT levels in the serum were also significantly decreased (p<0.05) after the program. Triglyceride levels significantly decreased from 194.9 mg/dL to 98.1 mg/dL (p<0.01) and the HDL cholesterol level significantly increased (p<0.01) from 55.8 mg/dL to 60.0 mg/dL after completion of the weight control program. Nutritional knowledge and eating behavior scores were significantly increased (p<0.001). In addition, the eating self-efficacy of the subjects was significantly increased (p<0.01); however, the food diversity scores were not changed after the program. These results suggest that the weight control program for adult obese women may be effectively used to promote weight reduction and improve nutritional knowledge and eating behavior.
This study was performed to document the weight loss diet practice and dietary habit related to weight control in child-bearing Korean women. The subjects were 1,434 women aged 17-39 years. The subjects were classified into 3 groups based on BMI: low weight(LW) BMI < 18.5; normal weight(NW), 18.5 BMI 22.9; and overweight(OW), 23.0 BMI. Anthropometric, general characteristics, weight control practice, and the quality of diet were assessed by a questionnaire. LW group had higher rate of smoking and drinking. They also complained more subjective symptom of anemia and used less nutritional supplementation. Weight loss diet had been practiced by about 40% of subjects and the percent was increased with increasing BMI. The reason of weight loss diet were significantly different by BMI groups(p<0.05); LW to keep body in shape, OW for health. Low BMI group had experienced more side effects after weight loss diet(p<0.05). LW group usually used inappropriate method to control weight such as skipping meals and some of OW group reported using drug to lose weight. All subjects have been skipped their meals of 3.9 times per week, especially 4.3 times in LW group. By mini dietary assessment, most of the subjects did not have regular meals. LW group tended to eat what they like and OW group preferred fried food. This study showed that child-bearing aged women make a ceaseless effort apart from their weight, and LW group have a matter of grave concern because of their dietary habit and weight control practice. Additional research should be necessary to assess the relation of health and weight loss diet in young women.
This study was conducted to identify the factors associated with weight control and nutritional knowledge of juvenile delinquents. The average heights of the subjects in this study were 172.20 cm (male) and 160.89 cm (female), and the average weights were 66.73 kg (male) and 58.42 kg (female), and the BMIs (Body Mass Index; $kg/m^2$) were 22.46 (male) and 22.54 (female). The results of this study revealed that 41.4% of the subjects were over weight or obese. In addition, there were significant differences in the BMI, satisfaction with body image and perception of body image observed between male and female subjects. Furthermore, female subjects were more experienced at weight control than male students (p<0.001). Additionally, overweight and obese individuals had more experience with weight control than subjects that were not overweight. Moreover, there were significant differences in the reason that subjects took weight control measured between male and female students. Specifically, female subjects practiced weight control due to their appearance (p<0.001). The order of methods by which male subjects attempted to control their weight was exercise>diet control>starvation and for girl student were diet control>starvation>excercise. The nutritional knowledge scores were higher for female subjects than for mele subjects. In addition, the nutritional knowledge scores increased as the BMI value increased and the $father^{\circ}{\emptyset}s$ educational level increased. These results of this study could be useful data to plan and develop nutritional education programs for juvenile delinquents.
