Objectives: The purpose of the study is to investigate the relationship between body mass index(BMI) and periodontal disease in Korean adult from the data of the fifth Korea National Health and Nutrition Examination Survey(KNHANES). Methods: The subjects were 3,309 adults from 25 ro 45 years old in the fifth KNHANES. The subjects were divided into three BMI categories: normal weight 1,549(BMI ${\leq}22.9kg/m^2$), overweight 792(BMI $23.0-25.0kg/m^2$) and obesity 968(BMI ${\geq}25.0kg/m^2$). Periodontal disease was assessed by community periodontal index(CPI) and periodontitis was defined as ${\geq}$ code 3. Results: Increased BMI adults had no significantly higher prevalence of periodontitis than those having normal body weight after adjusting for variables; the odds ratio(OR) was 1.06 in overweight and 1.23 in obesity. BMI and periodontitis had no significant relation to increased age, but the age increase tended to have high odds ratio. Women had a higher OR than men. Conclusions: Through this study, it is necessary to analyze the relationship between the obesity index and periodontitis in the further study.

Purpose: The purpose of this study was to investigate the health promotion behavior according to body mass index (BMI) and self-perception of obesity in female nursing students. Methods: The subjects of this study were 143 female nursing students. The data were collected using a questionnaire about health, life style and general characteristics. BMI, waist and hip circumference, flexibility, and gripping force were measured. Data were analyzed with SPSS/WIN 20.0 program. Results: Subjects were divided into three groups including true overweight (16.1%), false overweight (29.2%), and true normal weight group (43.5%) based on their BMI and self-perception about obesity. There were significant differences among the three groups in alcohol consumption, self-confidence on the accomplishment of desired weight in a year, gap between actual and desired weight, waist circumference, waist-hip ratio, and interpersonal relationship. The true normal weight group shows significantly higher interpersonal relationships than the true overweight group. Conclusion: It was determined that special strategies for increasing appropriate self-perception about obesity and health behaviors for female nursing students should be developed.

Along with the increasing interests of modem-day society toward topics of health and beauty, various studies are being actively conducted on the effects of diet for obesity prevention, and separate from aspects of disease prevention and health promotion. This study aimed to examine individual perceptions of obesity by age, and to prepare basic data for implementing an age-based weight control system, by comparing attitudes toward weight control. The research and analysis were conducted using questionnaires, provided to high school students(teenagers, 189 students), college students(20 or older, 116 students), and adults(30 or over, 88 adults) living in Daegu City. In terms of the respondents' perceptions of obesity, among those who described themselves as overweight, only about 10% were actually proven to be overweight. Also, significantly more female students than male students perceived themselves as overweight, despite the fact that they were in a normal weight range(p<0.007). There was no significant difference in the cause of obesity by gender, but it was found to be attributed to a lack of exercise for teenagers, and poor eating habits for those in their twenties and thirties. Concerning the intention to participate in a weight management class, the female teenagers showed significantly more interest than the male teenagers(p<0.017). Also, with regard to the respondents' attitudes toward weight control, the teenage females showed significantly higher interest in weight control than the teenage males p<0.003 and those in their twenties p<0.001. Moreover, regarding the period in which the respondents became most interested in weight, the teenage male students were most interested in weight during their middle school years and teenage females became most interested during their high school years. Therefore, the information from this study leads us to propose there is a need to correct the suggested reckless dieting that is occurring within an appearance-based society, as well as a need to establish a systematic weight control system, along with gathering subsequent basic data.

The purpose of this study was to investigate the dietary habits and snack consumption behaviors of middle school students with different obesity indexes in the Chungnam area. The survey was carried out using self-questionnaires and included 385 students(119 underweight, 193 normal weight, 66 overweight). The rate of skipping meals was higher for underweight students than overweight students; however, this difference was not statistically significant. The mean time of meal was 10 to 20 minutes and the criteria for choosing to eat a meal were 'hunger' and 'taste' in all groups. More than half of the subjects ate snacks 1 time a day, which were purchased outside. The typical snack time was 'between lunch and dinner'. The criteria of for consuming a meal were 'taste' and 'price' in all groups. In the underweight group, the snack food scores were ice cream(4.4), fruit(4.3), fried chicken(4.1), sports beverage(4.0), fruit juice(4.0), pizza(4.0) and, tteokbokki(3.9). In the normal weight group, the snack food scores were ice cream(4.3), fried chicken(4.2), pizza(4.0), sports beverage(3.9), fruit juice(3.9) and, tteokbokki(3.9) in the overweight group, the snack food scores were ice cream(4.3), fruit(4.3), fried chicken(4.2), yogurt(4.0), sports beverage(4.0), fruit juice(4.0) and, ramen(4.0). In conclusion, the snaking behaviors of the subjects were not significantly different based on their obesity index. However, this study may provide basic information on the snacking behaviors of middle school students, and the findings suggest that nutrition education or counseling can improve snack intake habits and positive behaviors toward healthy adolescents diets.

The purpose of this study was to provide basic informations for educating juveniles on desirable body image recognition by examining their body image recognition and comparing and finding problems according to gender and body mass index (BMI) in middle school students. The average age of the subjects was 15, their average height was 162.5 cm, their average weight was 53.5 kg, and their average BMI was $20.1\;kg/m^2$. Male students wanted to gain weight and female students wanted to lose weight. As for body shape, female students thought that they were fat more often than male students. Also the more overweight the students were, the higher their concerns and experiences toward weight control. Among weight control methods, exercise scored highest in all BMI groups. Over 80% of the respondents answered that their weight control effort were not systematic such as via professional counseling. As for the frequency of eating breakfast and dinner in female students, the more a student was overweight, the lower their frequency of eating breakfast and dinner. Many respondents answered that a typical meal time was '10~20 minutes'. The average eating habit score for all subjects was 38.0. The eating habit scores of male students were significantly higher than those of female students, and there were no significant differences among BMI groups. Eating habit score of 'I have more than two meals with rice everyday' in female overweight group was significantly higher than those of other two groups. These results indicate that the female students' degree of preference for a slim body shape were higher than those of male students. In addition, weight control by students is not systematic through professional counseling; instead they attempt to control their weight by themselves such as a meal skip, which lead to potential danger that they may lose weight carelessly. Therefore, correct body image recognition is greatly needed, and families and schools should make ceaseless efforts to help students properly control their weight and have correct eating attitudes.

Objectives Our purpose of this study was to evaluate the association between depression, stress, and obesity indexes. Methods This study was performed in 110 healthy overweight and obese(BMI${\geq}23\;kg/m^2$) women in Korea. Subjects underwent abdominal CT(computed tomography) scanning and were asked to complete Beck depression inventory(BDI), social readjustment rating scale(SRRS), and stress response inventory(SRI) questionnaires. Weight, body-mass index(BMI), waist circumference(WC), and waist-hip ratio(WHR) were evaluated. Subjects were given written consent and this study was performed under permission of institutional review board of KyunHee University Hospital at Gangdong. Results 1. BDI and SRI were significantly correlated with VFA(visceral fat area)(p<0.05). However, other obesity indexes were not significantly correlated with BDI and SRI(p>0.05). 2. SRRS was not significantly correlated with all obesity indexes(p>0.05). Conclusions This study suggests that depression and stress might be correlated with visceral fat, and this result would be helpful for planning a treatment schedule of obese patients with depression or stress in the clinic.

The purpose of this study was to determine anthropometric measurements, dietary nutrient intakes, simple food intake frequencies, and rates of obesity in Cambodian women. A total 186 women, aged 20-69 years, living in Kampong Spue province of Cambodia and having the responsibility to prepare family meals participated in this study. Height and weight were measured body mass index (BMI) was calculated, and one-day 24-hour recall and food frequency questionnaires were conducted. In total, 18.8% were underweight, 49.5% were normal weight, 13.4% were overweight, and 18.3% were obese according to the World Health Organization BMI standard for Asians. No significant difference in height by obesity level was determined ($p{\geq}0.05$). The mean energy intake was 1571.2 kcal/day and protein intake was 43.6 g/day. There were significant differences in protein, niacin, and vitamin C intakes by obesity level (p<0.05). The prevalence of subjects consuming vitamins and minerals less than 75% of Recommended Dietary Allowances was 73-99%. All Cambodian women consumed rice ${\geq}1time/day$. Approximately 50% of subjects reported ${\geq}1time/day$ intake frequency of bread, cookies, and chips. In total, 35% indicated no intake of beans or bean products. For intake frequencies of carbonated beverages and sports drinks, there was a significant difference by obesity level (p<0.05). These results may be very helpful to prepare nutrition education programs for Cambodian women.

This study was performed to study the effects of dietary factors on breast and cervical cancer incidence in female Koreans. The subjects were 60 breast and 109 cervical cancer patients recruited from five general hospitals in Seoul. Food intake, anthropometric measurement, and blood compositions were studied through personal interview and using medical records, from August 1991 to September 1992. Body weight, body mass index, triceps skinfold thickness and body muscle mass were at upper limit of normal value, which suggest that these patients had a tendency of overweight. The levels of hemoglobin and hematocrit of the patients were below the normal values. The values of serum protein, albumin, and calcium were in the normal range but close to the lower bound. Therefore the nutritional status assessed by blood composition seems to be marginal. The results of diet history showed that most of the nutrient intake of the subjects met with RDA. The fat intake were 22.9-36.9g/day which supplies about 15-16% of total calories. The results of this study do not agree with those reports of western societies which showed the positive correlation between calorie and fat intake and the incidence of breast and cervical cancer. Even through the calories and fat intake of the subjects were not high, it was higher than national average, especially in breast cancer patients. From this study, dietary factors does not seem to be a major risk factor in cancer incidence in Korea. However, the tendency of the increasing consumption of fat could be a contributing risk factor together with overweight.
