Chronic ills “prevalent” in US students


Chronic diseases such as high cholesterol and hypertension are widespread among US college undergraduates, a study suggests.

The survey of more than 800 18–24-year-olds at the University of New Hampshire found that 8% had metabolic syndrome – the combination of risk factors that is considered a precursor to heart disease.

In addition, at least one-third of the students, all of whom were enrolled in a general-education nutrition course, were overweight or obese – 60% of men had high blood pressure and more than two-thirds of women were not meeting their nutritional needs for iron, calcium or folate. “They’re not as healthy as they think they are,” said study leader Dr Ingrid Lofgren.

Students completed questionnaires on their lifestyle behaviours and dietary habits, chronicling their smoking, exercise, alcohol consumption, and consumption of fruits and vegetables. Their bodymass index was calculated and their waist circumference measured, and they were screened for blood pressure as well as glucose, triglycerides, and total and high-density cholesterol. The students also completed a three-day food diary and analysed their calorie, carbohydrate and nutrient intakes with nutrition software.

The researchers say many of the students were shocked by the results and the findings contradict the notion that college students are at the peak of health. Metabolic syndrome – a cluster of five risk factors (high blood pressure, excess abdominal fat, high blood glucose, high triglycerides, and low HDL cholesterol) that predicts the future development of heart disease and diabetes – was particularly prevalent in males.

In addition, 66% of males (compared to 50% of females) had at least one risk factor for metabolic syndrome and the vast majority of the students were not meeting nutrient recommendations for fibre, calcium and folate. Furthermore, 23% of men and 34% of women participated in less than 30 minutes of activity per day. On the plus side, the study noted, not many of the students smoked.

The researchers did say these students may be slightly healthier than their peers, since national rates for being overweight or obese in this group are close to 40%, but as another of the researchers, Dr Joanne Burke, said: “these individuals, if they continue on this trajectory, are going to be much more of a health burden at age 50 than their parents are.”

The researchers hope their findings will inform education policy, in terms of reducing portion sizes in dining halls and introducing routine blood pressure screening for students.
