The authors assessed the diet and exercise habits and perceived barriers to following a healthy lifestyle of 471 college students. Sixty percent of the participants were female and 31% had BMIs > 25. Breakfast was the most commonly missed meal and 63% of students snacked one to two times per day. Fifty-eight percent of participants ate vegetables and 64% ate whole or canned fruit less than once per day. Men consumed more soda and alcohol and used higher fat dairy, ate more meat, and ate fewer vegetables and fruits than women. Over half of the subjects rated their diet as poor or fair with “lack of time” listed as the number one barrier to eating well. Men exercised more frequently and at greater intensity than women and were more confident with their body image. The most common barrier to exercise was “lack of time.” The results of this study have implications for the design of general and specific diet and physical activity interventions among college students.

Introduction

Introduction
Diet related diseases including cardiovascular disease, cancer, and stroke are consistently among the top three leading causes of death (American Cancer Society, 2000). A new report, issued by the Institute of Medicine (IOM) of the National Academy of Sciences, suggests that to save the most lives from chronic disease, policy makers, health care providers and researchers should focus their efforts on helping people to stop smoking; maintain a healthy weight and diet; exercise regularly; and drink alcohol at low to moderate levels (American Cancer Society, 2003). Most college students may not achieve the nutrition and exercise guidelines designed to reduce the risk of chronic disease, typically consuming diets high in fat, sodium, and sugar and low in fruits and vegetables (Anding et al., 2001; Dinger & Waigandt, 1997; Grace, 1997; Hiza & Gerrior, 2002; TLHS, 2000). These poor eating habits may result from frequent snacking, excess dieting, and consumption of calorie dense but nutrient poor snacks and meals, such as those provided by fast food restaurants (Georgiou et al., 1997).

In addition, despite the recognized benefit of exercise, surveys of college students’ health habits indicate that only 35% have a regular schedule of physical activity and that a slightly higher proportion of men (40%) than women (32%) regularly exercise (Pinto et al., 1998). However, college students are at a time and place in their lives where their behavior is conducive to change. In fact, the students’ social role of learner is largely defined by a readiness to change (NIH, 1998). Therefore, college campuses serve as crucial settings to overcome perceived barriers to healthy diet and exercise habits, and implement effective interventions (Wallace et al., 2000). Ideally, if college students make positive changes in exercise and dietary habits, these changes could persist into adult years. The purpose of this survey was to assess the diet and exercise habits and perceived barriers to following a healthy lifestyle of college students and to determine if differences exist by gender. The results may have implications for the design of effective general and gender specific interventions for college students.
