Influence of exercise and dietary patterns on weight gain throughout college
Investigators: Susan S Deusinger PhD and Susan Racette PhD

Summary:

Lack of regular exercise, poor dietary habits, and obesity contribute substantially to adverse health consequences and early mortality. Approximately 30.5% of adults in America are classified as obese,1 and there is evidence that obesity during early adulthood can reduce life expectancy by as much as thirteen years.2 The greatest increases in overweight and obesity seem to occur between 18 and 29 years of age, based upon results of the Behavioral Risk Factor Surveillance System.3 Furthermore, there is evidence from the 1995 College Health Risk Behavior Survey that dietary and activity patterns of many college students predispose them to future health problems.4,5

Sedentary lifestyles contribute to overweight and obesity, and the transition from adolescence to early adulthood is accompanied by lifestyle changes that predispose young adults to become less physically active. Data from the National Health Interview Survey6 indicate that participation in vigorous aerobic and strengthening activities declines progressively from 12 to 21 years of age, and a continuous decline in physical activity is common until 29 years of age. The Centers for Disease Control and Prevention reported that only 25% of adults in America and only 25% of high school students engage in the recommended levels of physical activity,7 despite the overwhelming evidence that physical activity and exercise have favorable effects on weight control, disease prevention, and overall health at all ages.
