The authors surveyed 738 college students aged 18 to 27 years to assess overweight, obesity, dietary habits, and physical activity. They used BMI (body mass index) > or = 25 kg/m2 or BMI > or = 85th percentile and BMI > or = 30 kg/m2 or BMI > or = 95th percentile to estimate overweight and obesity in those aged < or = 19 years. To define overweight and obesity in those > or = 20 years, they used BMI > or = 25 kg/m2 and > or = 30 kg/m2. They found overweight rates of 21.6% using BMI directly and 16.2% using BMI percentile and obesity rates of 4.9% using BMI directly and 4.2% using BMI percentile. More than 69% of the participants reported < 5 servings of fruits and vegetables per day and more than 67% reported < 20 g of fiber per day; participants reported physical activity on fewer than 3 d/wk. Most college students are not meeting dietary and physical activity guidelines, suggesting the need for prevention interventions and increased understanding of overweight in college students.
作者对738名年龄在18至27岁之间的大学生进行了调查，以评估超重、肥胖、饮食习惯和身体活动情况。他们使用体重指数（BMI）≥25kg/m²或BMI≥第85百分位数以及BMI≥30kg/m²或BMI≥第95百分位数来估计19岁及以下人群的超重和肥胖情况。对于20岁及以上人群，他们使用BMI≥25kg/m²和≥30kg/m²来定义超重和肥胖。他们发现，直接使用BMI得出的超重率为21.6%，使用BMI百分位数得出的超重率为16.2%；直接使用BMI得出的肥胖率为4.9%，使用BMI百分位数得出的肥胖率为4.2%。超过69%的参与者报告称每天摄入的水果和蔬菜少于5份，超过67%的参与者报告称每天摄入的纤维少于20克；参与者报告每周进行身体活动的天数少于3天。大多数大学生未达到饮食和身体活动指南的要求，这表明需要采取预防干预措施，并加强对大学生超重问题的认识。
