A comparative study of food habits and body shape perception of university students in Japan and Korea

BACKGROUND: Abnormal body weight, dietary concerns, and unhealthy weight loss behaviors are increasingly being observed in young females in Japan. Our previous research has shown that the irregular lifestyles of female Japanese and Chinese students are significantly related to their desire to be thinner. In the present study, we compare the food habits and body shape preferences of female university students in South Korea and Japan to explore body shape perceptions in those populations. METHODS: A total of 265 female university students aged 19 – 25 years participated in this study. University students in Korea (n = 141) and university students in Japan (n = 124) completed a self-reported questionnaire. Data were analyzed using SPSS statistical software. Descriptive statistics were used to identify the demographic characteristics of the students and parametric variables were analyzed using the Student's t-test. Chi-square analyses were conducted for non-parametric variables. RESULTS: Comparison of body mass index (BMI) distributions in Japan and Korea showed the highest value in the normal category (74%) together with a very low obesity rate (1.2%). Significant differences were observed between the two countries in terms of eating patterns, with more Japanese eating breakfast daily and with Japanese students eating meals more regularly than Korean students. A difference was also observed in frequency of meals, where Korean students reported eating meals two times per day (59%) and the majority of Japanese students reported eating meals three times per day (81%). Although most subjects belonged to the normal BMI category, their ideal BMI classification was the underweight category (BMI: 18.4 ± 3.4). CONCLUSION: Few studies have compared the health related practices of Japanese and Korean university students. The present results suggest the necessity of nutrition and health promotion programs for university students, especially programs emphasizing weight management

Seasonal changes of nutrient concentration in Lake O-ike near Syowa Station, Antarctica

Seasonal variation of nutrients (phosphate, silicate, nitrate, nitrite and ammonium) at various depths of Lake 0-ike near Syowa Station, Antarctica was studied almost every month during the wintering season of 1987 (late March 1987 to mid-January 1988). Although concentrations of nutrients were generally low as in the case of the previous studies, it became clear that nitrate and ammonium increased considerably in the middle and bottom layers during the winter months. These increments may be attributed to degradation of dead planktonic and/or benthic algae and probably escaped observation in the former surveys. Phosphate could not be detected in the present survey, and nitrite was absent in the middle and bottom layers in the winter months
