ABSTRACT In this study, the obesity rate of children was 13.5%, and the value is not yet as high as the obesity rate in American children (Ha et al., 2005). However, the problem is the rapidly increasing obesity rate in Korean school children, as was already reported in other studies (Kang & Hong, 1997; Lee et al., 1999; You et al., 1997). The factors that are associated with obesity in this study included snacking, vegetable consumption, daily hours of physical activity and computer games/computer usage. Eating improper servings of vegetables or eating too much of fatty or sugary snacks are significantly associated with the development of obesity (Lee et al., 2000; Lee et al., 2002). The snacking prevalence and the daily intakes from snack in children has increased over the decade, thus leading to poor nutrition status and increased adiposity in children (Jahns et al., 2001, Niclas et al., 2001).More hours of physical activity and less hours of computer usage was found to be decreased the likelihood of being obese in this study (Table 3 & Table 4). These results were consistent with other studies showing positive correlation between physical inactivity and obesity in children (Andersen, 1998; Crespo, 2001; Epstein, 2001; Lowry, 2002). Data from the National Health and Nutrition Examination Survey (NHANES) III revealed that children who had physical inactivity 4 or more hours each day were most likely to be obese (Andersen, 1998). Lee et al. (2000) suggested that television viewing contributes to the development of overweight among children by reducing opportunities to engage in physical activity and increasing opportunities for snacking.In this study, girls had less likelihood of being obese than boys (odds ratio, 0.64, CI (0.43, 0.93), p

    ABSTRACT: The purpose of this study was to compare the beverage consumption by gender and season in elementary school children and to investigate the role of beverage consumption patterns on their daily nutrient intakes and BMIs. Beverage consumption and dietary energy intake in 160 elementary school students in the Gyeongnam area were measured by a beverage frequency and quantity questionnaire and three 24-hour dietary recalls during winter and summer. The number of drinking moments per month, the amounts of beverage per day, and the energy from beverage consumption were not different between winter and summer. In summer, the contribution of energy from sweetened beverage to the daily energy intake in girls accounted for 13.5% which was significantly higher compared to 7.7% in boys. In girls, the consumption of health beverage showed a significant correlation with various nutrient intakes in winter. Meanwhile, the sweetened beverage intake was negatively correlated with energy, protein, vitamin A and niacin intake in summer. Consumption of most of the beverages, including sweetened beverages, were not related with BMI in both sexes and both seasons, except functional drinks which were related with BMI in boys in winter.

    ABSTRACT: The purpose of this study was to determine the relationships between table attitudes(or table manners), nutrition knowledge, eating/snacking habits, and BMI in elementary school children. For the study, 350 [4~6th grade] elementary students were recruited and surveyed. Each response for 10 questions regarding table attitudes was scored by a 5-point scale(5 points=strongly agreed & 1 point=strongly disagreed) with a total score of 50. The reliability of 10 questions about nutrition knowledge was validated using Cronbach's (Cronbach's =0.80). Total scores for table attitudes were significantly different between the boys and girls(p

    ABSTRACT: To determine the relative effect of interactive digital exercise that features player movement (ie, exergames) on energy expenditure among children of various body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared). Comparison study. GoKids Boston, a youth fitness research and training center located at University of Massachusetts, Boston. Thirty-nine boys and girls (mean [SD] age, 11.5 [2.0] years) recruited from local schools and after-school programs. Six forms of exergaming as well as treadmill walking. In addition to treadmill walking at 3 miles per hour (to convert miles to kilometers, multiply by 1.6), energy expenditure of the following exergames were examined: Dance Dance Revolution, LightSpace (Bug Invasion), Nintendo Wii (Boxing), Cybex Trazer (Goalie Wars), Sportwall, and Xavix (J-Mat). Energy expenditure was measured using the CosMed K4B2 portable metabolic cart. All forms of interactive gaming evaluated in our study increased energy expenditure above rest, with no between-group differences among normal (BMI < 85th percentile) and "at-risk" or overweight (BMI ≥ 85th percentile) children (P ≥ .05). Walking at 3 miles per hour resulted in a mean (SD) metabolic equivalent task value of 4.9 (0.7), whereas the intensity of exergaming resulted in mean (SD) metabolic equivalent task values of 4.2 (1.6) for Wii, 5.4 (1.8) for Dance Dance Revolution, 6.4 (1.6) for LightSpace, 7.0 (1.8) for Xavix, 5.9 (1.5) for Cybex Trazer, and 7.1 (1.7) for Sportwall. Enjoyment of the games was generally high but was highest for children with BMIs in the highest percentiles. All games used in our study elevated energy expenditure to moderate or vigorous intensity. Exergaming has the potential to increase physical activity and have a favorable influence on energy balance, and may be a viable alternative to traditional fitness activities for children of various BMI levels.
