Weight loss practices and body weight perceptions among US college students

OBJECTIVE: The authors assessed associations between body weight perception and weight loss strategies. PARTICIPANTS: They randomly selected male and female college students (N = 38,204). METHODS: The authors conducted a secondary data analysis of the rates of weight loss strategies and body weight perception among students who completed the National College Health Assessment survey. RESULTS: Half of respondents (50%) were trying to lose weight, although only 28% of students were overweight or obese. Also, 12% of respondents had inaccurate body weight perception. Women and men with inaccurate body weight perception were significantly more likely to engage in inappropriate weight loss strategies than were those with accurate body weight perception. Of all students attempting to lose weight, 38% used both diet and exercise. CONCLUSIONS: These data show that college students are interested in weight loss and that body weight perception plays an important role in the desire to lose weight.     

Selected Health Behaviors That Influence College Freshman Weight Change

Objective and Participants: The authors investigated the effect of physical activity (PA), fruit and vegetable intake, and alcohol use on 6-month weight change in 193 college freshmen (78.8% white, 88.2% women, 94.5% on a meal plan). Methods: The authors administered a Web-based survey in fall 2002 (baseline) and spring 2003 (follow-up). Results: There was an overall average weight gain of 2.5 lbs (p < .05), although only 57% reported weight gain (M = 7.1 lbs). Fruit and vegetable intake decreased (p = .034), alcohol use increased (p > .05), and PA was unchanged. Weight gain for students with body mass indexes (BMI) ≥25 kg/m² was nearly twice that of students with BMIs < 25 (p < .05). Students with low-frequency baseline PA were twice as likely to be overweight. Follow-up data showed that students reporting ≥ 4 sessions per week (ie, high frequency) of low-intensity PA were twice as likely to have healthy BMIs as students engaging in low- and moderate-frequency PA. Conclusions: PA interventions should target freshmen with BMIs ≥ 25.     

Energy Drinks,Weight Loss,and Disordered Eating Behaviors

Abstract

Objective: The present study examined energy drink consumption and relations with weight loss attempts and behaviors, body image, and eating disorders. Participants/Methods: This is a secondary analysis using data from 856 undergraduate students who completed the American College Health Association–National College Health Assessment II confidentially online during February 2012. Results: This study revealed that the majority reported lifetime consumption of energy drinks (68.4%) and a substantial minority (30.2%) reported past-30-day consumption. Chi-square and t test results suggest that consumption is associated with concerns about personal appearance, weight loss attempts, and disordered eating behaviors (eg, vomiting). Hierarchical logistic regressions revealed that after controlling for demographics, the relations between energy drink consumption and the act of trying to lose weight, the use of diet pills, and the use of vomiting/laxatives remained significant. Conclusions: The current findings suggest that energy drink consumption is associated with weight loss attempts, poor body image, and unhealthy weight loss behaviors. Future research should examine the prevalence of energy drink consumption for the purpose of weight loss.     

Racial/ethnic differences in body weight perception among U.S. college students

Objective: To examine racial/ethnic differences in weight perception by sex among U.S. college students. Participants: a national sample (N = 70,267) of college students selected from 2- and 4-year postsecondary institutions (N = 62) during the Fall semester from 2011 to 2014. Methods: This is a secondary data analysis using 4 years of American College Health Association-National College Health Assessment IIb data. Sex-stratified multinomial logistic regression was performed to investigate racial/ethnic differences in body weight perception. Results: Compared with non-Hispanic whites, non-Hispanic black men and women were more likely to underestimate their body weight (p < .01). Asian men and women were more likely to overestimate their body weight than non-Hispanic whites (p < .001). Conclusions: Weight-related interventions should take into account racial/ethnic differences in body weight perception.     

“Drunkorexia”: Understanding eating and physical activity behaviors of weight conscious drinkers in a sample of college students

Objective: Behaviors of weight conscious drinkers (BWCD) include disordered eating, excessive physical activity (PA), and heavy episodic drinking. Considering that approximately 25% of the college students report BWCD, it is important to investigate what characteristics increase the likelihood of college students engaged in BWCD for both moderate and vigorous PAs. Participants: A total of 510 college students were recruited from a large, public southeastern university. Methods: Participants completed a cross-sectional survey during the spring 2015 semester. Results: Of 510 respondents, 11.2% reported moderate PA-based BWCD and 14.7% reported vigorous PA-based BWCD. Weight loss intention, BMI and Greek affiliation predicted both moderate and vigorous BWCD. Conclusions: Study findings suggest that Greek-affiliated students and students with weight loss intentions might be at an increased risk for BWCD. Along with promoting lower levels of alcohol consumption, college practitioners should consider discussing issues of weight and body image with college students as they relate to maladaptive drinking behavior.     

Influence of physical activity on weight status during the first year of college

Abstract

Objective: To provide an analysis of weight change in response to physical activity levels among first year college students. Participants: First year students (N?=?114) participated during the 2012–2013 academic year. Methods: Using a web-based survey, researchers gathered information on physical activity and weight at three points: twice throughout the fall and once at the end of the spring semesters. Results: Over half (56.25%) of respondents reported weight gain (between 0.45 and 13.61?kg) from baseline to 9-month follow-up. Weight gainers reported an average gain of 4.20?kg. More than half of participants were not meeting minimal recommendations for cardiorespiratory fitness (59.5%) and strength (53.2%) by the end of the first year of college. Conclusion: This research provides support for intervention and implementation of strategies to promote self-regulation in college students during the transition to college. Addressing the importance of physical activity in weight maintenance is beneficial to first year students’ well-being.     

Normative Beliefs as Risk Factors for Involvement in Unhealthy Weight Control Behavior

Objective: The authors' aim in this study was to determine, after adjustment for the effects of body mass index and sociodemographic measures, whether sex-specific weight control norms would have significant independent relationships with the weight control behavior of college women and men. Participants: The authors used an anonymous questionnaire to assess a sample of 470 college students, aged 18 to 26 years, attending either a 2- year community college or a 4-year public university. Methods: To calculate body mass index, the authors objectively measured the height and weight of each participant. They conducted separate discriminant function analyses for women and men. Results: The discriminant function analyses clearly indicated that weight control norms of same-sex, close friends were the best discriminators of involvement in weight control. Conclusions: The findings indicate that perceived peer norms may be important but overlooked risk factors for engaging in unhealthy weight control practices. The authors discuss the implications of these findings in the context of student health promotion.     

Eating and Exercise Disorders in Young College Men

Abstract

The authors used the computerized Eating and Exercise Examination to investigate eating, weight, shape and exercise behaviors in a convenience sample of 93 male college students. One fifth of the men worried about their weight and shape, followed rules about eating, and limited their food intake. Between 9% and 12% were unhappy with their body shape, felt fat, and seriously wanted to lose weight. Exercise was important for the self-esteem of 48% of the students. Thirty-four percent were distressed when they could not exercise as much as they wanted, 27% followed rules about exercising, and 14% worried about the amount of exercise they were doing. The respondents met clinical diagnoses for objective binge eating (3%), self-induced vomiting (3%), bulimia nervosa (2%), and exercise disorders (8%). Although 9% reported disordered eating, none had sought treatment. Health professionals should be aware that eating and exercise disorders may be present in college men and that screening may help in the early identification of these problems.     

Gender Differences in the Associations Among Body Mass Index,Weight Loss,Exercise, and Drinking Among College Students

Abstract

Objective: To explore gender differences regarding weight management behaviors of college drinkers. Participants: Nationally representative sample of college students from the fall 2008 American College Health Association's National College Health Assessment II (N = 26,062 students). Methods: Structural equation modeling was used to examine potential gender differences in associations among exercise, weight loss behaviors, and alcohol use. Results: Critical ratio tests revealed that associations between exercise and weight loss behaviors were more strongly correlated among females as compared with males. For females, there was a small negative association between exercise and drinking behaviors; in contrast, for males, there was a positive relationship between exercise and alcohol use. Weight loss behaviors were positively associated with drinking for both female and male students; however, the association was significantly stronger for females. Conclusions: This investigation furthers previous research on drunkorexia and also sheds additional light on the gender-based differences in weight management behaviors of drinkers.     

Understanding Weight Management Perceptions in First-Year College Students Using the Health Belief Model

Abstract

Objective: To examine weight management barriers, using the Health Belief Model, in first-year college students. Participants: First-year college students (n = 45), with data collected in April, May, and November 2013. Methods: Nominal group technique sessions (n = 8) were conducted. Results: First-year students recognize benefits to weight management beyond physical attractiveness to quality-of-life domains, including social (eg, bonding opportunities and energy to socially engage) and mental health (eg, stress management). Men believe that weight management is important for career/financial reasons, whereas women voiced that it will allow them to live a full, independent life with a high level of multitasking. Men believed that their barriers were external (eg, campus resources/programs), whereas females perceived their barriers to be internal (eg, poor time management). Conclusions: College students are challenged by weight management and want the institution to provide resources, including curriculum, to help them manage their physical activity and nutrition behaviors.     

The Freshman 15: Is it Real?

Objective: The belief that college students gain 15 Ibs during freshman year is widespread, yet the evidence for this is limited. The authors aimed to determine whether college students gain weight during freshman year. Participants: The authors studied unmarried freshmen living on-campus at a private university in the northeastern United States. Methods: The authors used an online survey to collect information about social behaviors and weight. Results: The authors observed an average weight gain of 2.7 Ibs. About half of the students gained weight, and 15% lost weight. Men gained more weight than did women. Conclusions: Freshman weight gain was 5.5 times greater than that experienced by the general population.     

College Health Professionals and Academic Librarians: Collaboration for Student Health

College health professionals must find new ways of educating students on finding and evaluating consumer health information, specifically in the online environment. Librarians are trained as information professionals; however, librarians at general academic libraries are not taking a lead role in providing consumer health information. Objective: The authors' purpose in this research was to determine the health information resource needs of college and university students and provide a model for collaboration between college health professionals and academic librarians. Participants and Methods: The authors compared data from a national survey on college health (N = 54,111) with their own results from a survey of general academic librarians (N = 17) to create recommendations for synching students' reported health information needs with librarians' resources. Results: Although the Internet was students' second most-often consulted health information source, they ranked the believability of online health information above only television. In the librarian survey, although 12 respondents indicated that health information provision is a library's responsibility, the majority (n = 11) believed their library's consumer health outreach to be passive. Conclusions: The authors offer recommendations for partnerships between college healthcare professionals and academic librarians to better provide this information to students.     

Rural-urban differences in college students’ cardiovascular risk perceptions

Abstract

Objective: To examine rural-urban differences in college students’ cardiovascular risk perceptions. Participants: College students in rural (n?=?61) and urban (n?=?57) Kentucky counties were recruited from November 2012 to May 2014. Methods: This was a secondary data analysis of a cross-sectional study examining rural-urban differences in cardiovascular risk factors. Students rated their risk for developing high blood pressure, diabetes, high cholesterol, heart disease, having a stroke, and gaining excess weight. Chi-square and logistic regression were used for data analysis. Results: Rural students had lower odds of perceived high risk for developing high blood pressure compared to urban students (odds ratio (OR): 0.32, 95% CI: 0.11–0.96) after adjusting for race, sex, and body mass index. This association was not observed after adjusting for healthcare access variables. No other significant differences were observed. Conclusions: Efforts to raise perceived risk for developing hypertension among rural college students may be warranted.     

Differences in Dietary Patterns Among College Students According to Body Mass Index

Objective and Participants: The authors surveyed 557 undergraduate students aged 18-56 years to assess weight status, health behaviors, and dietary variety. Methods: They used body mass index (BMI) to divide students into 4 weight categories: underweight (BMI < 19 kg/m²), healthy weight (19 kg/m² to 24.99 kg/m²), over-weight (25 kg/m² to 29.99 kg/m²), and obese (> 30 kg/m²). Results: Approximately 33% of respondents were overweight or obese, and 8% were underweight. Among the weight categories, the authors observed significant differences in diet (eg, cheese, pork, lamb, veal and game, fish, green leafy vegetables, other vegetables, and the cumulative total of all meats). Overall, 33% of the students consumed 1 fruit in 3 days. The authors found no differences among the weight categories related to eating fatty, sugary snacks. Conclusions: College administrators should create health promotion and skill-building programs to improve students' diet variety.     

A Population-Wide Screening and Tailored Intervention Platform for Eating Disorders on College Campuses: The Healthy Body Image Program

Abstract

Objectives: This article presents a new approach to intervention for eating disorders and body image concerns on college campuses, using a model of integrated eating disorder screening and intervention. Formative data on implementation feasibility are presented. Participants: College students enrolled at 2 universities between 2011 and 2012. Methods: The Healthy Body Image program is an evidence-based screening and intervention platform, enacted via community and online resources. An online screen was used to identify students at varying levels of risk or eating disorder symptom status; responses were used to direct students to universal or targeted online interventions or further evaluation. Universal prevention programs to improve healthy weight regulation and body image culture were offered to all students. Results: Formative data from 1,551 students illustrates the application of this model. Conclusions: The Healthy Body Image program is feasible to deliver and provides a comprehensive system of screening, evidence-based intervention, and community culture change.     

My Student Body: Effects of an Internet-Based Prevention Program to Decrease Obesity Among College Students

Abstract

Objective: To determine the impact of My Student Body (MSB)–Nutrition, an Internet-based obesity prevention program for college students. Participants: Three hundred and twenty ethnically diverse undergraduate students were randomly assigned to 1 of 3 conditions: MSB-Nutrition program, an on-campus weight management course, and a comparison group. Methods: Students completed baseline and follow-up surveys regarding their nutrition and physical activity behaviors, self-efficacy, stress, attitudes, and body weight. Results: Compared with the on-campus course and a comparison group, the MSB-Nutrition program increased fruit and vegetable consumption, reduced stress, and increased fruit and vegetable self-efficacy but had no significant effect on students’ exercise self-efficacy, exercise behavior, or weight loss. Conclusions: The MSB-Nutrition program was effective in changing students’ nutrition behaviors but had no effect on physical activity behaviors or weight loss. Suggestions for improving Internet-based interventions aimed at decreasing obesity rates among college students are offered.     

Risk Factors Associated With Overweight and Obesity in College Students

College obesity is increasing, but to the authors' knowledge, no researchers to date have evaluated risk factors in this population. Objective: The authors assessed whether abnormal eating perceptions and behaviors were associated with overweight in college students. Participants and Methods: A sample of undergraduates (N = 4,201) completed an online survey containing demographic questions and the Eating Attitudes Test-26 (EAT-26) questionnaire. The authors stratified participants into normal-weight and overweight/obese groups and evaluated physical activity, EAT-26 score, purging behaviors, and answers to selected overweight screening questions on the basis of body mass index. A modified EAT-26 score of ≥ 11 was associated with overweight (p = .016). Results: Compared with normal-weight peers, overweight participants displayed an increased fear of bingeing, preoccupation with food, desire to be thinner, and engagement in dieting behavior. Mean body mass index also increased with age and physical inactivity (p < .001). Conclusions: Because physical inactivity, disordered eating perceptions, and disordered behaviors are associated with increased rates of overweight and obesity, identification of these risk factors in obese youths may increase understanding of weight loss barriers and facilitate the treatment of adolescent obesity.
