Adolescence is an important period with rapid physical growth transitioning from childhood to adulthood. Distorted body image can result in eating disorders or inadequate nutrient intakes in adolescence. Limited research has been done with high school boys in both Korea and China.
To examine body image, weight control behaviors, nutritional knowledge, and dietary habits in Korean and Chinese teenage boys, and to evaluate any differences in these measures between two countries.
High school boys in Yongin of Korea and Weihai region of China (n=201 Korean and n=196 Chinese) participated in a selfreport survey. A previously validated questionnaire assessed height and weight, body image, nutritional knowledge, and dietary habits. Descriptive statistics, t-test, Chi-square, and Pearson correlations were used for data analysis.
About 41.4% of Korean students and 40.8% of Chinese students desired to be thinner. The majority of the students from both countries showed a perception gap between ideal body image and current body image. Korean students had a higher frequency of weight control attempts compared with Chinese students (p=0.004). Overall, Korean students had higher scores in nutritional knowledge (p<0.001), while Chinese students had higher scores in dietary habits (p<0.001). Nutrition knowledge in Korean students and dietary habit in Chinese students showed positive correlation with body shape satisfaction (p<0.01).
The findings of this study support that developing proper body image among high school boys is important in Korea and China. Different educational strategies might be beneficial to Korean or Chinese students.
青春期是从儿童向成人过渡的身体快速生长的重要时期。身体意象扭曲会导致青春期出现饮食失调或营养摄入不足。韩国和中国针对高中男生的相关研究较少。
研究韩国和中国青少年男性的身体意象、体重控制行为、营养知识和饮食习惯，并评估两国在这些指标上的差异。
韩国龙仁市和中国威海地区的高中男生（韩国201名，中国196名）参与了一项自填式调查。一份经过验证的问卷评估了身高、体重、身体意象、营养知识和饮食习惯。采用描述性统计、t检验、卡方检验和皮尔逊相关性分析进行数据分析。
约41.4%的韩国学生和40.8%的中国学生希望变瘦。两国的大多数学生在理想身体意象和当前身体意象之间存在认知差距。与中国学生相比，韩国学生尝试控制体重的频率更高（p = 0.004）。总体而言，韩国学生在营养知识方面得分更高（p < 0.001），而中国学生在饮食习惯方面得分更高（p < 0.001）。韩国学生的营养知识和中国学生的饮食习惯与身体形状满意度呈正相关（p < 0.01）。
本研究结果支持在韩国和中国，培养高中男生正确的身体意象很重要。不同的教育策略可能对韩国或中国学生有益。
