This study was conducted to compare body shape satisfaction, body image perception, weight control status, and dietary habits of Korean and Chinese female high school students in order to provide information for proper body image perception of adolescents. 221 students in Yongin, a city in Korea, and 227 students in Weihai, a city in China, were surveyed using questionnaires. Body shape satisfaction was significantly higher in Chinese students (P < 0.001) compared to Korean students. 76.2% of Korean students and 72.7% of Chinese students wanted a thinner body shape than their present body shapes. Experiences of weight control, laxative or diuretics uses, eating during weight control, and vomiting after eating were significantly higher in Korean students (P < 0.05-P < 0.001) compared to Chinese students. The score for dietary habits was significantly higher in Chinese students (P < 0.001) compared to Korean students, suggesting a more desirable dietary habit among Chinese students. Students of both countries showed a significantly positive correlation between body shape satisfaction and dietary habits, suggesting that as body shape satisfaction increases, dietary habits become more desirable. In conclusion, Korean female students showed a more distorted body image perception and had more poor dietary habits than Chinese students. Nutritional education for the establishment of normal body weight, proper body image perception, and healthy dietary habits are needed.

BACKGROUND/OBJECTIVES: College students are in a period of transition from adolescence to adulthood, in which proper dietary habits and balanced nutritional intake are very important. However, improper dietary habits and lifestyles can bring several health problems. This study was performed to investigate blood lipid profiles, blood aluminum and mercury in college students and the relationships among them. SUBJECTS/METHODS: The subjects were 80 college students (43 males and 37 females) in Gyeonggi-do. General characteristics, anthropometric measurements, blood pressure, blood lipids, SGOT, SGPT, and blood aluminum and mercury of the subjects were measured and analyzed, and their relationship was studied. RESULTS: The BMI was significantly higher in males, 23.69 ± 3.20 kg/m², than in females, 20.38 ± 2.37 kg/m² (P < 0.001). The blood pressure was significantly higher in males with 128.93 ± 12.92 mmHg systolic pressure and 77.14 ± 10.31 mmHg diastolic pressure compared to females with 109.78 ± 11.97 mmHg and 65.95 ± 6.92 mmHg, respectively (P < 0.001). HDL cholesterol in males, 61.88 ± 13.06 mg/dl, was lower than 64.73 ± 12.16 mg/dl in females, but other blood lipid levels were higher in males. Blood aluminum was significantly higher in males, 9.12 ± 2.11 µg/L, than in females, 8.03 ± 2.14 µg/L (P < 0.05), and blood mercury was higher in males, 3.08 ± 1.55 µg/L, than in females, 2.64 ± 1.49 µg/L. The blood lipids showed positive correlation with obesity and blood pressure. CONCLUSIONS: The degree of obesity, blood pressure, triglycerides, and LDL cholesterol were higher in males, suggesting possible association with chronic disease incidence such as hyperlipidemia and hypertension. Thus, it is considered that a systematic health education is needed for college students, especially for males.

BACKGROUND/OBJECTIVES: Dietary behavior and life stress in adolescence is related to growth rate and learning ability. This study was conducted to identify the relations between dietary habits, dietary attitude nutritional knowledge and life stress among high school girls in Korea and China. SUBJECTS/METHODS: The subjects of this study were 221 high school girls in Korea and 227 high school girls in China. The questionnaire were about dietary habits, dietary attitude, nutritional knowledge and life stress. RESULTS: The dietary habits of chinese girls were healthier than those of Korean girls with a significant difference (P < .001). There was no significant difference in dietary attitude between Korean girls and Chinese girls. Korean girls had more nutritional knowledge than Chinese girls with a significant difference (P < .001). Korean girls did less physical exercise but spent more time watching TV and using PCs, compared to Chinese girls. Korean girls' degree of confidence in nutrition information that they had learned and their performance in their real lives were low. Also, they had a low level of awareness of the need for nutritional education. There was no significant difference in life stress between the two groups. Dietary habits had a significantly negative correlation with life stress in both Korean and Chinese girls (P < .01, P < .001). As for Chinese students, dietary attitude had a negative correlation with life stress with a significant difference (P < .05). As for Korean girls, nutritional knowledge had a negative correlation with life stress with a significant difference (P < .05), which means as life stress was less, dietary habits were better. CONCLUSIONS: This study shows that effective nutrition education programs should include components that encourage application of learned nutrition information to real life, increase physical exercise and reduce life stress.
