The authors surveyed 738 college students aged 18 to 27 years to assess over weight, obesity, dietary habits, and physical activity. They used BMI (body mass index) [greater than or equal to] 25 kg/m[squared] or BMI [greater than or equal to] 85th percentile and BMI [greater than or equal to] 30 kg/m[squared] or BMI [greater than or equal to] 95th percentile to estimate overweight and obesity in those aged [less than or equal to] 19 years. To define overweight and obesity in those [greater than or equal to] 20 years, they used BMI [greater than or equal to] 25 kg/m[squared] and [greater than or equal to] 30 kg/m[squared]. 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 less than 5 servings of fruits and vegetables per day and more than 67% reported less than 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.
