Purpose: This study examined the changes in the nutrient intake and the prevalences of obesity and metabolic syndrome according to the eating alone behavior in middle-aged men and women. Methods: The data from the 2013 ~ 2017 Korean National Health and Nutrition Examination Survey were analyzed. A total of 7,728 adults (3,404 male, 4,324 female) aged 40 ~ 64 years old were included. The subjects were classified into three groups according to the number of times eating alone per day (0, 1 ~ 2, and 3 times/day). Dietary data were collected by a 1-day 24-h recall. The nutrient intakes were compared among the three groups. Survey logistic regression analyses were conducted to examine the association of the eating alone behavior with obesity and metabolic syndrome, adjusting for the related confounding variables. Results: In men, eating alone was associated significantly with a lower intake of potassium (p-for-trend = 0.048) and lower intake of calories from protein (p-for-trend = 0.04). In women, the proportion of subjects consuming energy less than 75% of the estimated energy requirement (p = 0.001) and less than the estimated adequate requirement of riboflavin (p < 0.001) differed significantly according to the eating alone behavior. The eating alone behavior was positively associated with an increased risk of developing metabolic syndrome (p-for-trend = 0.033), increased blood pressure (p-for-trend < 0.001), and increased waist circumference (p-for-trend = 0.004). On the other hand, in women, however, the eating alone behavior was associated with a decreased risks of developing obesity (p-for-trend = 0.02). No association was found between the eating alone behavior and the risk of metabolic syndrome in women. Conclusion: These results suggest that the eating alone behavior is a risk factor for the development of metabolic syndrome in middle-aged Korean men.

Purpose: The purpose of this study was to investigate the relationships among TV involvement, body image concern, restrained eating behavior and self-esteem of middle school students in one city. Methods: A cross-sectional survey design was used. A total of 229 boys and 267 girls enrolled in the middle schools completed self report questionnaire in June, 2009. The data was analyzed by using SPSS/WIN 17.0. Results: Of boys, 24.5% was over-weight/obese while 12.7% of girls was over-weight/obese. Compared to boys, girls involved more in TV (p<.001), and showed more body image concern, and restrained eating behavior (p<.001), but had lower self-esteem (p=.020). A significant positive correlation between TV involvement and body image concern was found in both boys and girls. However, only girls showed a negative association between TV involvement and self-esteem, and as well as between restrained eating behavior and self-esteem. As grouped by BMI, both boys and girls showed significantly different scores in restrained eating behavior (p<.001). Conclusion: These results suggest that the increased number of obese young adolescent need a weight management program including control for unhealthy eating behavior. The influence of mass-media on distorted body image for adolescents should be corrected. Also, an intervention for young obese girls to promote their self-esteem needs to be developed.

Objectives : The purpose of this study was to examine the eating behavior of patients in a bid to facilitate the improvement of their eating behavior, as eating behavior seemed to affect oral health and dietary habits. Methods : The subjects in this study were 235 patients who visited the dental hygiene practice lab at C college in South Jeonla Province. After a survey was conducted, the collected data were analyzed with the statistical package SPSS 12.0. Results : 1. When their self-awareness of dietary habits and oral health was checked in consideration of eating behavior, those who thought they had very good dietary habits and were in good oral health had meals three times a day. Their eating time was very irregular, and they took 15 to 20 minutes to eat. Their overeating frequency was three or four times a week, and their frequency of eating between meals was once or twice a week. 2. On the contrary, the daily eating frequency of the patients who found themselves to have very bad dietary habits and to be in bad oral health was not fixed, and their eating time was neither regular nor irregular. They spent less than 10 minutes having a meal, and their overeating frequency was once or twice a week. Their frequency of having a snack was three or four times a week, and as for food preference, they had a liking for meat. 3. The patients considered themselves to be in better health when they had balanced meals and good eating behavior, namely good dietary habits. And they rated their own dietary habits higher when they were in a good oral state, had no experiences to feel pain in the mouth and didn't receive any dental treatment, namely when they were in good oral health. Conclusions : This study attempted to investigate the influence of eating behavior on oral health awareness. Another limitation of this study is that the geographic scope was just confined to an urban community in South Jeonla Province without checking any possible regional gaps. However, it's quite evident that eating behavior exerts an influence on oral health awareness, and it seems worth doing to examine a larger number of subjects by utilizing objective oral health guidelines.

This study was performed to investigate the eating habit, body image, and weight control behavior by BMI in Korean female high school students. Data on the 16,574 subjects was obtained from the sixth Korea Youth Risk Behavior Web-based Survey (2010). Only 52.2% of the subjects had regular breakfast. The rate of skipping breakfast was higher in the underweight group than in the obese group, but the rate of skipping dinner was on the contrary to this. Underweight students had a higher intake frequency of fruits, fast food, instant noodle, and snacks than the obese groups. 3.5% of underweight students considered themselves to be overweight or obese. 53.4% of obese students considered themselves to be overweight. The experience of weight control increased according to BMI, but underweight students considered weight control as an effort to be slimmer. Meal restriction was used more frequently to control weight. The perceived stress level was higher in obese student, especially due to appearance. Therefore, an appropriate, integrated and personalized high school nutrition program should be established for proper body image perception and to develop the self-esteem of female high school students.

Purpose: The theory of planned behavior (TPB) was used to investigate how the psychological constructs of attitude, subjective norms, and perceived behavioral control (PBC) affect the individual intention of behaviors in adults. Social support is also important in enabling the stability of healthy eating. This study examined the relationship between three major constructs of TPB as well as social support and the intention of healthy dietary behaviors in adults residing in Beijing, China using the extended TPB. Methods: The study questionnaire was based on previously validated items and an online survey was conducted from October to November 2020. Using a total of 244 Chinese adults in Beijing, multiple linear regression analysis was used to test the relationships between three major constructs of TPB as well as the social support and intention of healthy eating. Results: Among the three major constructs of TPB, subjective norms (p = 0.044) and PBC (p = 0.000) were significantly related to the behavioral intention of healthy eating (p = 0.000), and the model explained 76.6% of the variance of the behavioral intention from the three constructs of TPB included in the multiple linear regression model. The additional inclusion of social support to the model did not increase the explanatory power of the model to describe the behavioral intention of healthy eating. The subjective norms (p = 0.040) and PBC (p = 0.000) were still significant where social support did not explain the variance of the behavioral intention adequately. Conclusion: The subjective norms and PBC may be potential determinants of the behavioral intention of healthy eating in adults residing in Beijing, China. These study results can be used to promote healthy eating in Chinese adults living in urban areas. Large-scale intervention studies will be needed to determine if social norms and PBC predict the actual behaviors of healthy eating in Chinese adults.

This study compared actual weight with perceived weight, described the prevalence of unhealthy weight control behavior, determined the differences in psychological and personal variables between participants that reported unhealthy weight control behavior and those who did not, and examined the relationship of eating habits to unhealthy weight control behavior for Korean adolescents. The study population consisted of a nationally representative sample of middle and high school students who completed the Fifth Korea Youth Risk Behavior Web-based Survey (KYRBWS): Fifth in 2009. Among the 75,066 participants of KYRBWS, 35,473 (n = 18,851 girls and 16,622 boys) were eligible for a research focused on unhealthy weight control behavior. The results of this research were as follows: First, there were considerable discrepancies (45.1% of girls and 32.8% of boys) between the perceived weight and the actual weight. Second, overall, unhealthy weight control behavior was more prevalent in girls and fasting was the most commonly reported behavior. Third, participants that reported unhealthy weight control behavior scored significantly lower on scaled measures of happiness, health, academic achievement, and economic status; in addition, they scored higher on stress measures. Fourth, girls and boys shared common protective factors of having breakfast and vegetables more often, perceiving their weight as underweight rather than overweight, and having a correct weight conception. Protective factors unique to girls were having lunch and dinner more often. Girls and boys shared common risk factors of the consumption of soda, fast food, instant noodles, and snacks more often, while consumption of fruit more often was a risk factor only for girls. The improvement of protective factors and minimization of risk factors through Home Economics classes (and other classes relevant to health) may mitigate unhealthy weight control behavior of adolescents.
