The principal objective of this study was to identify the dietary and physical activity patterns of obese preschoolers, and to determine the association between child obesity and mother's' dietary habits or thoughts regarding dieting/weight. This is a cross-sectional, community based study, and 305 preschoolers who attended kindergarten in Seoul and its surrounding area were selected. The measurements of dietary habits both in preschoolers and their mothers, physical activities of preschoolers, and daily servings of foods were based on parents' self report. Weight and height were used to calculate WLI (weight length index) in preschoolers and BMI (body mass index) in their mothers. The subjects were divided into two groups 245 normal weight preschoolers (including underweight 15.1% and normal weight 65.6%) and 59 obese subjects (overweight 14.4% and obese 4.9%). With regard to dietary habits in normal and obese preschoolers, we noted significant differences in 5 questions, such as mostly eating heavy meals, one serving size, eating speed, overeating, and obsession about eating. No differences in daily servings of major foods and snacks, except fruits and potatoes, were noted between normal and obese children. Among 13 questions regarding mothers' dietary habits, only 3 questions-"preferred to instant foods", "finish meals within 15 minutes", "use nutritional information for selecting foods" were significantly different between normal and obese subjects. The total scores of mothers' dietary habits was significantly and negatively correlated with number of mother's dieting experiences or mother's BMI, but was not correlated with preschooler's obesity.

Objectives: Many studies have shown that social distancing, as a non-pharmaceutical intervention (NPI) that is one of the various measures against coronavirus disease 2019 (COVID-19), is an effective preventive measure to suppress the spread of infectious diseases. This study explored the relationships between traditional health-related behaviors in Korea and social distancing practices during the COVID-19 pandemic. Methods: Data were obtained from the 2020 Community Health Survey conducted by the Korea Disease Control and Prevention Agency (n=98 149). The dependent variable was the degree of social distancing practice to cope with the COVID-19 epidemic. Independent variables included health-risk behaviors and health-promoting behaviors. The moderators were vaccination and unmet medical needs. Predictors affecting the practice of social distancing were identified through hierarchical multiple logistic regression analysis. Results: Smokers (adjusted odds ratio [aOR], 0.924) and frequent drinkers (aOR, 0.933) were more likely not to practice social distancing. A greater degree of physical activity was associated with a higher likelihood of practicing social distancing (aOR, 1.029). People who were vaccinated against influenza were more likely to practice social distancing than those who were not (aOR, 1.150). However, people with unmet medical needs were less likely to practice social distancing than those who did not experience unmet medical needs (aOR, 0.757). Conclusions: Social distancing practices were related to traditional health behaviors such as smoking, drinking, and physical activity. Their patterns showed a clustering effect of health inequality. Therefore, when establishing a strategy to strengthen social distancing, a strategy to protect the vulnerable should be considered concomitantly.

Physical activity (PA) professionals and participants recognize enhanced quality of life (QoL) as a benefit of and motivator for PA. However, QoL measures are often problematic and rarely consider the participants' perspective. This paper focuses on recent findings from a larger project on the role of QoL in PA and health promotion. More specifically, we focus on the views of participants and potential participants to better understand the relationship of PA and QoL. In earlier stages of the project we began with a conceptual model of QoL and developed a survey. We now focus on participants' views and ask two questions: 1) what is QoL? and 2) how does PA relate to QoL? We first asked those questions of a large sample of university students and community participants as open-ended survey items, and then asked focus groups of community participants. Overall, participants' responses reflected the multidimensional, integrative QoL model, but the responses and patterns provided information that may not be picked up with typical survey measures. Findings suggest that PA contributes to multiple aspects of QoL, that social and emotional benefits are primary motivators and outcomes for participants, and that the meaning of QoL and PA benefits is subjective and contextualized, varying across individuals and settings. Programs that directly target and highlight the multiple dimensions and integrative QoL, while considering the individual participants and contexts, may enhance both PA motivation and participants' health and QoL.

The purpose of this study was to investigate the correlation and characteristics between electromyographic (EMG) activities of lower leg muscles and the posturographic assessment of static balance control in normal adults. Twenty-four young, healthy adults(12 males, 12 females) participated in the study. Center of pressure (COP) parameters were obtained using force platform as total path distance, total sway area, X mean frequency and Y mean frequency for 20 seconds in the following conditions: (1) comfortable standing with eyes opened or closed, (2) uncomfortable standing (feet together) with eyes opened or closed, (3) virtual moving surround delivered using Head mount display (HMD) with four different moving patterns. The virtual moving patterns consisted of close-far, superior-inferior tilting (pitch), right-left tilting (roll), and horizontal rotation (yaw) movements. Surface electromyographic activites were recorded on the tibialis anterior, peroneus longus, medial and lateral heads of gastrocnemius muscles under each condition. Correlation between the posturographic measures and EMG activities were evaluated. Total path distance and total sway area of COP were significantly increased during uncomfortable standing. EMG activity of tibialis anterior was significantly more during uncomfortable standing and virtual moving surround stimulation than during comfortable standing. Total path distance and sway area of COP during comfortable standing with closed eyes showed significant positive correlation with the EMG activities of the lateral head of gastrocnemius muscle. Total path distances and total sway area of COP during muscle. Total path distances and total sway area of COP during presentation of virtual moving surround also had significant positive correlations with EMG activities of the lateral head of gastrocnemius muscle under close-far movement.

This study was intended to provide basic data of nutrition education to a prevention of obesity and living patterns of elementary school students. Through the measurment of the actual obesity rate of children for students who were in the fifth and sixth grades of elementary school as well as their mothers, and by analyzing obesity-related factors. Children have started to have the characteristics obesity and obesity problems. 1. There were total 234 children including 133 boys (56.8％) and 101 girls (43.2％) for the study. There were 80 children in the fifth grade (34.2％) and 154 children in the sixth grade (65.8％). 2. Among the subjects 20.1％ were obese. By gender, the obesity rate of boys (27.1％) was higher than that of girls (l0.9％)(p＜0.01). By grade, children in the fifth grade (26.3％) had higher obesity rate than children in the sixth grade (l6.9％)(p＜0.05). 3. In terms of the educational level of parents, the obesity rate of children of parents who received university and／or higher education was 27.5％ (p＜0.05). 44.1％ of parents answered ‘I almost never give snack’s’(p＜0.01). 4. There was 32.8％ for an irregular quantity of meal. There was no obese child who under-ate (p＜0.05). In terms of impulse eating, ‘I eat.’ and ‘I don't eat.’ were 24.4％ and 25.9％ respectively. The obesity rate of the case of ‘I eat only food I like.’ was 10.6％ (p＜0.05). In terms of the obesity rate based on the daily average meal frequency, there was the highest rate of 26.1％ for I average meal frequency per day, 13.0％ for 2 daily average meal frequency, and 7.4％ for over 3 average meal frequency per day (p＜0.05). For a degree of a physical activity, the group of active physical activity (p＜0.05) and the group which liked the physical exercise showed a lower obesity rate (p＜0.001). The obesity rate of children who had regular exercise was 11.8％. It was lower than the obesity rate (24.8％) of children who didn't exercise (p＜0.01). The higher exercise frequency per week was, the lower the obesity rate was(p＜0.01). In terms of the exercise time, there was 8.3％ for over 60 minutes and 28.9％ for less 15 minutes. The group which had the long exercise time showed a lower obesity rate(p＜0.05). As the result, the education for obesity must enable students to recognize the warning signs for obesity and control their own weight with proper living patterns, by modifying behaviors considering the degree of obesity. Obesity must be controlled by the prevention and education connected with the family for all students as one of the school health programs. There must be also the development of a program through individual consultation considering the degree of obesity.

Objectives: The objective of the study was to examine the clustering patterns and correlates of multiple health behaviors (MHBs) in middle-aged Koreans with metabolic syndrome (MetS). Methods: Data on sociodemographics, clinical characteristics, health behaviors (vegetable intake, physical activity, cigarette smoking, and alcohol consumption), and psychological characteristics were collected by a self-reported survey and medical examination from 331 individuals with MetS. Clustering of MHBs was examined by measuring 1) the ratios of observed and expected prevalence of MHBs, and 2) the prevalence odds ratios. A binomial logistic regression were conducted. Results: Men were more likely than women to engage in multiple unhealthy behaviors. Clustering of smoking and heavy drinking was exhibited in the participants. Women with high vegetable intake were more likely to be physically inactive, and those with inadequate vegetable intake were more likely to be physically active. Those with lower self-regulation were more likely to engage in unhealthy behaviors. Conclusions: The findings support the multiple health behavior approach as opposed to the individual health behavior approach. Emphasis of self-regulation is necessary in developing multiple behavior intervention for individuals with MetS.

Over the past few decades, changes in patterns of behavior (e.g., diet, smoking, alcohol consumption, and physical activity) have led to major changes in health status, characterized by increases in obesity, Type II diabetes mellitus, cardiovascular disease, and some cancers. This epidemiologic transition is largely the result of rapid increases in immigration to developed countries and rural-urban migration within developing countries, which is usually accompanied by environmental and lifestyle changes. In particular, adoption of “Western” dietary patterns, which tend to be high in fat and low in fruits and vegetables, is of concern since diet is a potent contributor to chronic disease risk. However, until recently, the process by which immigrants and rural-urban migrants adopt the dietary practices predominant in their new environments, known as dietary acculturation, has received very little research attention. Dietary acculturation is multidimensional, dynamic, and complex, and varies considerably depending on a variety of personal, cultural, and environmental characteristics. Therefore, to intervene successfully on the negative aspects of dietary acculturation, it is important to understand the process and identify factors that predispose and enable it to occur. The purpose of this article is to provide a practical model for understanding and investigating the effect of dietary acculturation on food and nutrient intake. Thus, this report 1) gives an overview of acculturation, 2) defines dietary acculturation and presents a model for how it occurs, 3) discusses measurement issues around dietary acculturation,4) reviews the literature on dietary acculturation in Korean Americans; 4) suggests a paradigm for acculturation research; and 5) offers some recommendations for future research in this area.

The purpose of this study was to determine health consciousness and eating habits of workers at Deluxe hotels in Seoul and Gyonggi-do. To determine health levels, this study focused on quality of sleep, current state of health, smoking, drinking, regular exercise, dietary behavior patterns, dietary habits, and food intake patterns. Out of 228 subjects, 145 (63.6%) were males and 83 (36.4%) were females. Majority of workers (86.9%) graduated from university. A majority (57.0%) worked more than 10 years. Average health condition was 'little tired', whereas 18.4% of subjects were 'always tired'. Male percentages for smoking and drinking were higher than those for females. A total of 44.3% of workers ate twice a day. Regular physical activity was high, but regular exercise rate was slightly low. Male average eating speed was faster than that of females and had lower scores for desirable eating habits. Shift workers ate night meals more than non- shift workers. This study shows that workers at Deluxe hotels need to take better care of their health.

In this study, 230 female college students in Seoul area were surveyed to evaluate their eating habits and behavior, physical activities, and patterns of purchasing diet/low-calorie food. Their body composition was also determined using bioelectrical impedance(Inbody 520). The subjects were divided into two groups according to their BMI index with a mean BMI of 20.2$\pm$1.5(normal) weight and 25.0$\pm$1.7(obesity). Overall, 85.7% of the subjects reported that the food they purchase depends more on their preferences than the nutritional value of the food. When the two groups were compared there was no significant difference in the frequency or experience of purchasing diet-foods. Indeed, 69.3% of all female college students had purchased diet foods, and most consumed these foods 2~3 times a week. Obese group preferred a savory taste, while normal group preferred a sweet taste. The majority of the subjects(80.8%) answered that they "read nutritional labels carefully upon purchasing diet food", and that they examined calories(61.8%) and total fat(48.5%) most carefully. Of the types of low-calorie/diet foods purchased, beverages were the most commonly obtained; followed by noodles, diet-bars, and snacks. The most commonly purchased low calorie snacks were "potato-type C(hot-flavor)" and "potato-type A(salty-flavor)", while the most commonly purchased diet-bars were "low calorie-type A"(55.3%) and "high protein-bar"(32.3%). The most commonly purchased noodles were "thick noodle type"(65.1%), while the most commonly purchased drinks were "cereal tea"(65.1%) and "mixed herb tea"(66.0%). Overall, factors such as self-esteem or the degree of body satisfaction, rather than obesity(BMI index) itself, were significantly correlated with the frequency of purchasing diet-foods.

본 연구에서는 서울 및 수도권에 거주하는 65세 이상의 노인이 매일 느끼는 일상적 행복감(daily happiness)이 일주일 동안 변동하는지, 매일의 사회적 교류와 신체활동이 개인 내 일상적 행복감의 변동과 어떤 관련성을 갖는지 탐색한다. 다음으로, 노인의 성별, 연령, 학력, 건강에 따라 사회적 교류 및 신체활동과 일상적 행복감 사이의 관련성이 달라지는지 살펴본다. 마지막으로 일상적 행복감의 수준과 변동이 전반적 행복감(global happiness) 수준과 어떻게 관계되는지 확인한다. 이를 위하여 일주일 동안 수집한 생활일지(daily diary) 자료(n=175명${\times}$7일=1225응답)와 동일 기간 동안 활동량계로 수집한 신체활동 자료(n=16명${\times}$7일=112응답)를 활용하여 위계적 회귀분석과 위계적 선형모형(HLM)으로 분석하였다. 분석결과 첫째, 노인의 일상적 행복감 수준은 일주일 동안 변동하고 노인의 젠더와 건강에 따라 일상적 행복감의 수준과 변동 정도에 차이가 있었다. 둘째, 자녀와 대화한 날과 친구와 만난 날 노인의 일상적 행복감이 더 높아졌고, 형제자매와의 만남은 일상적 행복감 수준에 유의한 영향을 미치지 않았다. 하지만 건강상태와의 상호작용항을 투입 결과, 건강하지 않은 노인은 건강한 노인에 비해 형제자매와 만난 날 일상적 행복감이 더 큰 폭으로 높아지는 것이 발견되었다. 셋째, 많이 걸은 날은 일상적 행복감 수준이 높았으며, 저강도 활동시간이 긴 날은 일상적 행복감의 수준이 낮아졌다. 넷째, 일상적 행복감 수준과 전반적 행복감 수준 사이에는 긍정적 관계가 관찰되었으나, 일상적 행복감의 변동 정도는 전반적 행복과 유의미한 관련성을 보이지 않았다. 이상의 결과가 갖는 함의와 후속연구에 대한 제언을 제시하였다.
