Increasing sugar intake of population has become a nutritional issue in Korea. Sweet taste perception may be related to behaviors such as eating sweet food including high sugars and total sugar intake. This study aimed to evaluate objective and subjective sweet taste perception and the association among objective sweet taste perception, dietary behaviors related to eating sweet snack food including high sugar, and total sugar intake from the snacks. Participants were 261 healthy female college students (mean age: $21.0{\pm}1.6years$), who were divided into three subgroups based on oral sweet taste evaluation using a sweet taste assessment tool provided by Ministry of Food and Drug Safety: sweet-seeker group (n=139), medium sweet-seeker group (n=54), and unsweet-seeker group (n=68). There was no significant difference in weight and body mass index (BMI) among the three groups; however, the sweet-seeker group had significantly higher sweet taste preference than that of the other groups. Though more people in the sweet-seeker group thought they tended to eat sweet foods than the medium sweet-seeker and unsweet-seeker groups, over half of the sweet-seekers did not think they tended to eat sweet foods. The sweet-seeker group was more likely to eat sweet snacks such as breads, chocolate products, sugar-sweetened milk, and so on than the unsweet-seeker group. Total sugar intake from the selected sweet snacks was 44.4 g for the sweet-seeker group, 34.4 g for the medium sweet-seeker group, and 28.0 g for the unsweet-seeker group with a significant difference. These results indicated the absence of relationship between objective sweet taste perception and the obesity index; however, significant associations were detected among objective sweet taste perception, eating sweet snacks and total sugar intake from the snacks. We also found high disagreement between objective and subjective sweet taste perception of the subjects. The present study provided the novel insight that measuring objective sweet taste perception may be useful for assessing the risk of high sugar consumption and undesirable dietary behaviors.

Two hundred sixty six children were retrospectively surveyed from first to fifth grade to find out the status of obesity during four years. The obesity index was gained by height and weight data from student's health file and the data about eating behaviors and weight control behaviors, etc. were collected by questionnaires. Children assigned to one of the following groups : underweight, normal, overweight and obese. The results were as follows ; 1. Obese children were 18.6%(n=27) of boys and 10.8%(n=13) of girls at fifth grade. 2. Twenty eight children among forty obese children at fifth grade were also overweight or obese at first grade, and the other twelve was normal. 3. Breakfast skipping rate was significantly high among underweight and obese group of boys(p<0.01).The most children(87.6%) had prejudice for special foods. 4. The rate of agreement between obesity index and self recognition of body image was 60.7% in boys and 63.6% in girls. 5. Forty two point five percent of children have ever tried weight control as exercise(35.7%), reducing sugars and snacks(27%), fasting(23.8%), avoiding fatty foods(12.7%), taking diet food or drug(0.8%). In conclusion, the prevalence of children obesity is gradually increasing and children tried weight control without right guidances. In order to prevent progress into adulthood obesity, nutrition education should be followed with school foodservice including the right perception for obesity, proper weight control and eating behavior modification.

Purpose: The purpose of this study was to examine the relationship between eating disorders and parent-adolescent communication in middle school students. Method: There were 267 adolescents taken as participants from two middle schools in rural areas. Data were collected from June to July 2005, using the Eating Disorder Inventory-2 questionnaire (23 items) and Parent-Adolescent Communication Inventory (10 items for open family communication, 10 items for problem in family communication). The SPSS Win version 12.0 was used for descriptive analysis, t-test, and partial correlation coefficient. Result: The mean score on the eating disorder was 2.74 (range: 1-6). Meanwhile, the mean scores on the parent-adolescent communication was 3.37 (range: 1-5). There were significant differences in eating disorders according to gender, age, negative perception of the participant's body weight, family's perception of obesity, diet experiences, and BMI. Eating disorders showed a significant negative correlation with parent-adolescent communication. Conclusion: In this study, there was a significant negative correlation between eating disorders and parent-adolescent communication. In order to prevent an eating disorder, education and training to enhance communication skills should be provided to adolescents and their parents as well.

The purpose of this study was to compare energy intake according to expected body mass index (BMI) in adolescents. A total of 280 middle school students were divided into current or/and expected obesity groups (underweight group; UWG, normal weight group; NWG, and overweight group; OWG) by BMI to compare energy intake and perception on body shape and weight control. The average age of total subjects was 15 years, and the distributions of boys and girls were 52.5% and 47.5%, respectively. The distribution of boys and girls was not significantly different among current obesity groups but was among expected obesity groups (15% and 82% in UWG vs. 71.4% and 16.5% NWG vs. 13.6% and 1.5% in OWG; P<0.001), indicating that girls wanted to lose weight more than boys. For body shape, most subjects in current obesity groups responded "fitness" in UWG (38.7%), "fitness" and "slightly chubby" in NWG (45.5% and 39%), and "slightly chubby" in OWG (65.2%), showing a significant difference (P<0.001). For interest in weight control, most subjects responded "average" in current UWcinterested" in current OWG (52.2%), whereas they responded "very interested" in expected UWG (55.7%), "average" in expected NWG (51.2%), and "not interested" in expected OWG (45.5%), showing a significant difference (P<0.001). The percentage of subjects with experience with weight control was significantly high in current OWG (71.7%), NWG (51.2%) and UWG (34.2%) as well as in expected UWG (57.3%), NWG (40.2%) and OWG (36.4%) in descending order (P<0.001). The daily energy intake of total subjects was 2,057.1 kcal without any significant difference among current obesity groups. However, it was significantly lower in expected UWG than expected NWG and OWG (1,943.1 kcal vs. 2,165.0 kcal or/and 2,152.1 kcal; P<0.001). To sum up these results, girls wanted to lose weight more than boys. The more students wanted to lose weight, the greater their experience and interest in weight control and the lower their energy intake.

The purpose of this study was to identify the body shape satisfaction and body shape esteem according to the state of obesity in elementary school students. The data were collected from May 1st to 31th, 1999 using the questionnaire and the physical examination record. The subjects were 669 in 12-year old children. Data were analyzed with frequency, percentages, crosstabs, ANOVA, pearson correlation using the SPSS program. The results were as follows: 1. The prevalence of overweight was 14.0% of total students, 21.4% of mail students and 6.6 % of female students. 2. There were significant differences in the body shape satisfaction according to the state of obesity in total students(($chi^2$ = 110.31, p = .000), in mail students(($chi^2$ = 99.97, p = .000), in female students(($chi^2$ = 62.23, p = .000). The percentages of the body shape satisfaction were highest the underweight group in total and female students but in mail students the normal weight group was highest 3. There were significant differences in the body shape esteem according to the state of obesity in total students(F = 8.634, p = .000), in mail students(F = 11.738, p = .000), in female students(F = 4.502, p = .004). The mean scores of body shape esteem were highest the normal weight group in total students, overweight group in mail students and underweight group in female students. The higher the state of obesity was, the lower body shape esteem. 4. The relationships between body shape satisfaction, body shape esteem and obesity index were significant. Obesity index were significantly and negatively related to body shape satisfaction(r = -.2081, P = .000), to body shape esteem(r = -.2250, p = .000). 5. There were significant differences in the state of obesity according to sex(($chi^2$ = 88.136, p = .000) and the perception of body shape(($chi^2$ = 242.371, p = .000) in total students. There were significant differences in the state of obesity according to the body shape of father(($chi^2$ = 15.11, p = .019), the perception of body shape(($chi^2$ = 138.95, p = .000) in mail students. There were significant differences in the state of obesity according to the education of mother(($chi^2$ = 19.46, p = .022), the perception of body shape(($chi^2$ = 143.35, p = .000) in female students.

Society's emphasis on a thin body ideal may intensify an individual's negative perceptions of fatness. The purpose of the present study was to examine the relationship between sociocultural attitudes toward appearance (awareness and internalization of the female ideal) and anti-fat attitudes among middle-aged Korean women. In addition, the aim was to examine whether the body internalization of female ideals was a mediator in the proposed model. Participants included a sample of 264 middle-aged Korean women who completed a series of measures online. The following information was collected through online questionnaires: awareness and internalization of the female ideal, attitudes toward fat, body weight perception, and demographics. Data were analyzed using correlation analysis, descriptive analysis, factor analysis, and structural equation modeling. The measurement model and the structural model testing provided an acceptable fit to the data, and all proposed pathways in the research model were statistically significant. Awareness of the female ideal was significantly and positively associated with internalization, and it significantly and positively predicted both constructs of anti-fat attitudes. Additionally, awareness of the female ideal was significantly and positively indirectly associated with attitudes toward fat people-dislike and willpower mediated by internalization. Overall, these findings suggest that society's emphasis on female appearance and a thin body can ultimately result in significant stigmatization of overweight/obese individuals. This study emphasizes the importance of establishing a healthy appearance standard to reduce anti-fat prejudice.

The purpose of this study is to identify the BMI, diet perception and diet behavior of female university students. A descriptive survey design was used 165 students from October 29 to November 9, 2018. Data were analyzed using mean, t-test, ANOVA, cross analysis with SPSS 21.0. Total diet perception was 3.44 points, highest sub category was 'practice' with 4.00 points, followed by 'information and education' with 3.58 points, 'necessity' with 3.32 points and lowest category was 'self-recognition' with 2.84. 65 students(43.0%) were 'less than three times' in 'Number of diets' and diet methods was 65(43.0%) for 'food control' and 62(41.1%) for 'exercise'. During in a week, 98 students(84.9%) exercised within three hours, followed by 33(21.9%) who did not exercised at all. 22 students(14.6%) said they experienced damage from dieting, while the types included gastrointestinal disease, menstrual irregularity and hair loss. The total score of diet perception according to BMI was lower in the underweight group than in the normal and overweight groups(p<.001). In diet 'practice' category, low weight group scored lower than normal weight and overweight groups(p<.05). In 'information and education' category, overweight group scored the highest, followed by normal and underweight groups(p<.001). In diet 'necessity' and 'self-recognition' categories, low weight group scored lower than normal weight and overweight groups(p<.001). Diet behavior by diet perception was different in number and method of diet(p<.001). Based on the results, it is thought that attention and education are needed to form a proper diet perception and maintain healthy living for female university students.

This study examined the socioeconomic factors that affect self-rated health (SRH) in healthy adults, and the relationship of SRH to health-related habits, serum biochemical indices, and nutritional intakes. Subjects consisted of 1,154 healthy adults without any known disease, aged 19 to 65 years (average age of 36.7), whose information was obtained from the 2013 Korean National Health and Nutritional Examination Survey data. Of these subjects, 73 rated themselves as 'very healthy,' 460 indicated that they were 'healthy,' 568 self-identified as 'ordinary', and 53 put themselves in the 'unhealthy' category. The proportion of subjects who chose 'unhealthy' was significantly increased with higher frequencies of disruptions in their daily lives (p<0.05), regret after drinking (p<0.05), smoking (p<0.001), and higher levels of stress (p<0.001). On the other hand, the proportion of subjects reported as 'very healthy' was significantly higher with regular intense (p<0.001) or moderate physical activities (p<0.05), regular walking (p<0.05), a perception of being 'normal' in their body image (p<0.01), a decrease of body weight more than 3 kg in the past year (p<0.05), and without risk factors for metabolic syndrome (p<0.05). Serum triglyceride level was lower, and 25-(OH) vitamin D content was significantly higher, in the 'very healthy' group as compared to the 'unhealthy' group (p<0.05). Dietary fiber and vitamin C intakes were significantly higher in the 'very healthy' group than 'unhealthy' group (p<0.05). The overall results suggest that a healthy lifestyle, including regular exercise, non-smoking, good stress management, and higher intakes of fiber and vitamin C, may be potential factors that affect one's positive perception of health.

The purpose of this study is to collect fundamental data for adult female health improvement based on urban adult female obesity and cardiopulmonary function. Surveyed were 859 adult females who visited a health improvement center in D district in Seoul between April, 1999, and December, 1999, and the resulting data are as follows: 1. The adult female mean BMI was $23.97{\pm}3.11kgm^2$, which comes within the range of overweight. Among them, BMI of the females aged 41-60, and over 60, were significantly higher. Mean percentage of body fat was $32.07{\pm}4.63$, and it significantly increased in accordance with age, recording the highest among those aged over 60. 2. The systolic blood pressure significantly increased in accordance with age, recording highest among those aged over 60. Those aged 41-60 and over 60 showed significantly higher diastolic blood pressure than those in their 20s and 30s; however, they had a significantly lower heart rate. Vital capacity and maximum oxygen intake significantly decreased in accordance with age, and those aged over 60 were lowest. 3. As to health perception, 20.6% of the subjects perceived themselves as healthy, and those who perceived themselves as unhealthy showed significantly higher BMI than those who perceived themselves to be of moderate health. 4. There were no significant differences in blood pressure, heart rate and maximum oxygen intake in accordance with health perception, but those who perceived themselves as healthy showed significantly higher vital capacity than those who didn't. 5. As to cardiopulmonary function in accordance with obesity, the obese group showed significantly higher systolic blood pressure than those whose weight was normal to overweight. The diastolic blood pressure of the normal weight group was the lowest, while the obese group showed significantly lower vital capacity and maximum oxygen intake. These findings indicate that the womens' health promotion program must include an effective strategy for preventing obesity, and strengthening cardiopulmonary function.
