相关理论呈现：身体习性与社会阶层差异存在密切关系。本研究以B大学教育学部大一、大二、大三、大四学生为研究对象，从身体习性的身材、穿着、食物偏好、居住环境偏好、社会交往、消费情况、道德品质、兴趣爱好等维度出发，进行了问卷调查和深度访谈。 结果表明，不同社会阶层大学生在身体习性的消费情况、道德品质、兴趣爱好、特长、对社会阶层的看法等方面存在较为显著的差异，而在身材、穿着、食物偏好、居住环境偏好等方面的差异不显著，有纵向变化的特点，且存在大学生自身、他人和社会因素的影响。因此，家庭、大学和社会应更多关注大学生身体习性的养成，以更好地促进他们成长与发展。

Relevant theories show that there is a close relationship between body habits and social class differences. This study takes students, freshmen, sophomores, juniors, and seniors of the Faculty of Education of University B as research subjects, starting from the dimensions of body habits, dress, food, living environment, social interaction, consumption, moral quality, and hobbies. A questionnaire survey and in-depth interviews were conducted. The results show that there are significant differences in the consumption of social habits, moral qualities, hobbies, specialties, and perceptions of social class among college students of different social strata, but the differences in body, clothing, food, and living environment preferences are not. Significant, there are vertical changes in characteristics, and there are college students themselves, others and social factors. Therefore, families, universities and society should pay more attention to the development of college students' physical habits in order to better promote their growth and development.
