The purpose of this study was to assess weight status, dietary habits, physical activity, dietary beliefs, and nutrition knowledge among a sample of students from Central Michigan University.
A cross-sectional survey was conducted among a sample of undergraduate students in Fall 2011 and Spring 2012 at Central Michigan University. Participating students completed an online questionnaire that included questions related to their eating habits, physical activity and lifestyle, dietary beliefs, and nutritional knowledge. Weight, height, and waist circumference were measured. Percentage body fat and visceral fat score were determined using a Tanita body composition analyser (SC-331S).
Outcomes of this study indicated that 78% of female students were within the healthy weight range compared to 52% of male students. Visceral body fat and waist circumference scores were higher in males than in females. Most students showed 'satisfactory' dietary habits. Almost half of the students reported drinking two glasses of milk and consuming two cups of fruits and vegetables daily. Physical activity and lifestyle score indicated that most of the students were not physically active. Only 7% of students reported having a very active lifestyle, and 4% had quite good nutritional knowledge.
The majority of students, particularly females, were within the healthy body weight range. Students' dietary habits were satisfactory. However, physical activity, students' knowledge of healthy and unhealthy diet habits, and nutritional knowledge needed improvement. Developing gender-specific programmes for promoting healthy lifestyle behaviours among students is recommended.
本研究旨在评估中密歇根大学学生样本的体重状况、饮食习惯、身体活动、饮食观念和营养知识。
2011年秋季和2012年春季，对中密歇根大学的本科生样本进行了横断面调查。参与的学生完成了一份在线问卷，其中包括与他们的饮食习惯、身体活动和生活方式、饮食观念以及营养知识相关的问题。测量了体重、身高和腰围。使用Tanita人体成分分析仪（SC - 331S）测定体脂百分比和内脏脂肪评分。
本研究结果表明，78%的女生体重处于健康范围内，而男生这一比例为52%。男性的内脏脂肪和腰围评分高于女性。大多数学生的饮食习惯“令人满意”。几乎一半的学生报告每天喝两杯牛奶，食用两杯水果和蔬菜。身体活动和生活方式评分表明，大多数学生身体活动不足。只有7%的学生报告生活方式非常活跃，4%的学生营养知识相当良好。
大多数学生，尤其是女生，体重处于健康范围内。学生的饮食习惯令人满意。然而，身体活动、学生对健康和不健康饮食习惯的了解以及营养知识需要改进。建议制定针对性别的计划，以促进学生养成健康的生活方式行为。
