Impact of an online healthful eating and physical activity program for college students.

Purpose. To identify impact of an online nutrition and physical activity program for college students. Design. Randomized, controlled trial using online questionnaires and on-site physical and fitness assessments with measurement intervals of 0 (baseline), 3 (postintervention), and 15 months (follow-up). Setting. Online intervention delivered to college students; a centralized Web site was used for recruitment, data collection, data management, and intervention delivery. Subjects. College students (18–24 years old, n = 1689), from eight universities (Michigan State University, South Dakota State University, Syracuse University, The Pennsylvania State University, Tuskegee University, University of Rhode Island, University of Maine, and University of Wisconsin). Intervention. A 10-lesson curriculum focusing on healthful eating and physical activity, stressing nondieting principles such as size acceptance and eating competence (software developer: Rainstorm, Inc, Orono, Maine). Measures. Measurements included anthropometrics, cardiorespiratory fitness, fruit/vegetable (FV) intake, eating competence, physical activity, and psychosocial stress. Analysis. Repeated measures analysis of variance for outcome variables. Results. Most subjects were white, undergraduate females (63%), with 25% either overweight or obese. Treatment group completion rate for the curriculum was 84%. Over 15 months, the treatment group had significantly higher FV intake (+.5 cups/d) and physical activity participation (+270 metabolic equivalent minutes per week) than controls. For both groups, anthropometric values and stress increased, and fitness levels decreased. Gender differences were present for most variables. First-year males and females gained more weight than participants in other school years. Conclusion. A 10-week online nutrition and physical activity intervention to encourage competence in making healthful food and eating decisions had a positive, lasting effect on FV intake and maintained baseline levels of physical activity in a population that otherwise experiences significant declines in these healthful behaviors.

Internet-based Interventions Have Potential to Affect Short-term Mediators and Indicators of Dietary Behavior of Young Adults

OBJECTIVE Evaluate a theory-based, Internet-delivered nutrition education module. DESIGN Randomized, treatment-control design with pre-post intervention assessments. SETTING AND PARTICIPANTS Convenience sample of 160 young adults (aged 18-24) recruited by community educators in 4 states. Study completers (n = 96) included a mix of racial/ethnic groups and family demographics, but were predominately white females without children. INTERVENTION A Transtheoretical Model (TTM)-based, stage-tailored Internet program, F&V (Fruit & Vegetable) Express Bites, was delivered to treatment group participants; controls received nontailored messages in a comparable format. MAIN OUTCOME MEASURES AND ANALYSIS: TTM constructs at baseline, immediately postviewing, and at 30-day follow-up were compared via chi-square, McNemars test, and logistic regression. Qualitative use and acceptability indicators were collected postviewing (treatment only). RESULTS Of baseline respondents, 86.5% completed the study. At follow-up, self-efficacy, decisional balance, and selected processes improved for both groups, with only marginal advantages for the theory-based version. Fruit and vegetable consumption changes were similar for both groups. Qualitative measures of knowledge, confidence, and motivation improved (not measured for controls). Favorable ratings of treatment program acceptability and personal relevance were reported. CONCLUSIONS AND IMPLICATIONS The Internet is a favorable option for reaching young adults with nutrition messages. This study did not identify strong advantages of theory-based tailoring, especially for fruit consumption, which had weaker barriers than vegetable consumption among this target audience.

The Effects of Young Adults Eating and Active for Health (YEAH): A Theory-Based Web-Delivered Intervention

OBJECTIVE To assess the effectiveness of a tailored theory-based, Web-delivered intervention (Young Adults Eating and Active for Health) developed using community-based participatory research process. DESIGN A 15-month (10-week intensive intervention with a 12-month follow-up) randomized, controlled trial delivered via Internet and e-mail. SETTING Thirteen college campuses. PARTICIPANTS A total of 1,639 college students. INTERVENTION Twenty-one mini-educational lessons and e-mail messages (called nudges) developed with the non-diet approach and focusing on eating behavior, physical activity, stress management, and healthy weight management. Nudges were short, frequent, entertaining, and stage-tailored to each behavior, and reinforced lesson content. MAIN OUTCOME MEASURE All participants were assessed at baseline, postintervention (3 months from baseline), and follow-up (15 months from baseline) for primary outcomes of weight, body mass index (BMI), fruit and vegetable intake (FVI), physical activity (PA), and perceived stress; and secondary outcomes of waist circumference, percent dietary fat, energy from sugar-sweetened beverages, servings of whole grains, self-instruction and regulation for mealtime behavior, hours of sleep, and stage of readiness for change for consuming 5 cups of FVI, completing 150 minutes of PA/wk, and managing stress on most days of the week. Demographics were collected at baseline. ANALYSIS Chi-square analysis and mixed-models repeated measures analysis were performed to determine differences between experimental and control outcomes. RESULTS There were no differences between experimental and control participants in BMI, weight, and waist circumference. There were small improvements in FVI (P = .001), vigorous PA in females (P = .05), fat intake (P = .002), self-instruction (P = .001), and regulation (P = .004) for mealtime behavior, and hours of sleep (P = .05) at postintervention, but improvements were not maintained at follow-up. At postintervention, a greater proportion of experimental participants were in the action/maintenance stages for FVI (P = .019) and PA (P = .002) than control. CONCLUSIONS AND IMPLICATIONS Young Adults Eating and Active for Health is one of the first studies to use the community-based participatory research process of PRECEDE-PROCEED to develop a non-diet approach intervention. Although there were no differences between experimental and control participants in weight change or BMI, the intervention supported positive change in behaviors that may mediate excessive weight gain, such as increasing FVI and more healthful self-regulation mealtime behaviors immediately postintervention. Additional strategies to maintain the behavior changes need to be explored.

Sweet and salty. An assessment of the snacks and beverages sold in vending machines on US post-secondary institution campuses.

This study assessed the nutritional quality of snacks and beverages sold in vending machines. The contents of snack and beverage vending machines in 78 buildings on 11 US post-secondary education campuses were surveyed. Of the 2607 snack machine slots surveyed, the most common snacks vended were salty snacks (e.g., chips, pretzels) and sweets (i.e., candy and candy bars). The 1650 beverage machine slots assessed contained twice as many sugar-sweetened beverages as non-calorie-containing beverages. Only two institutions sold both milk and 100% juice in vending machines. The portion of snacks and beverages sold averaged more than 200 cal. Neither snacks nor beverages were nutrient dense. The majority of snacks were low in fiber and high in calories and fat and almost half were high in sugar. Most beverages were high in calories and sugar. This studys findings suggest that vending machines provide limited healthful choices. Findings from benchmark assessments of components of the food environment, like the vending options reported here, can provide valuable input to campus administrators, health services, food service, and students who want to establish campus policies to promote healthful eating.

The Medicine Wheel Nutrition Intervention: A Diabetes Education Study with the Cheyenne River Sioux Tribe

OBJECTIVE The Northern Plains Indians of the Cheyenne River Sioux Tribe have experienced significant lifestyle and dietary changes over the past seven generations that have resulted in increased rates of diabetes and obesity. The objective of this study was to determine if Northern Plains Indians with type 2 diabetes mellitus who are randomized to receive culturally adapted educational lessons based on the Medicine Wheel Model for Nutrition in addition to their usual dietary education will have better control of their type 2 diabetes than a nonintervention, usual care group who received only the usual dietary education from their personal providers. DESIGN A 6-month, randomized, controlled trial was conducted January 2005 through December 2005, with participants randomized to the education intervention or usual care control group. The education group received six nutrition lessons based on the Medicine Wheel Model for Nutrition. The usual care group received the usual dietary education from their personal providers. PARTICIPANTS One hundred fourteen Northern Plains Indians from Cheyenne River Sioux Tribe aged 18 to 65 years, with type 2 diabetes. METHODS Weight, body mass index (BMI), hemoglobin A1c, fasting serum glucose and lipid parameters, circulating insulin, and blood pressure were measured at the beginning and completion. Diet histories, physical activity, and dietary satiety surveys were measured at baseline and monthly through completion. Differences were determined using Student t tests, chi(2) tests, and analysis of variance. RESULTS The education group had a significant weight loss (1.4+/-0.4 kg, P<or=0.05) and decrease in BMI (1.0+/-0.1, P<or=0.05) from baseline to completion. The usual care group had no change in weight (0.5+/-0.5 kg) or BMI (0.5+/-0.2). There were no between group differences due to intervention in energy, carbohydrate, protein, and fat intake and physical activity. CONCLUSIONS The culturally based nutrition intervention promoted small but positive changes in weight. Greater frequency and longer duration of educational support may be needed to influence blood glucose and lipid parameters.

Assessment of the dining environment on and near the campuses of fifteen post-secondary institutions

OBJECTIVE The present study evaluated the restaurant and dining venues on and near post-secondary campuses varying in institution size. DESIGN The Nutrition Environment Measures Survey for Restaurants (NEMS-R) was modified to evaluate restaurants as fast food, sit down and fast casual; and campus dining venues as dining halls, student unions and snack bar/cafe´s. ANOVA with post hoc Tukey’s B and T tests were used to distinguish differences between dining venues and associated institutions by size. SETTING The study was conducted at fifteen US post-secondary institutions, 2009–2011. SUBJECTS Data presented are from a sample of 175 restaurants and sixty-eight on-campus dining venues. RESULTS There were minimal differences in dining halls by institution size, although medium-sized institutions as compared with small-sized institutions offered significantly more healthful side dish/salad bar items. Dining halls scored significantly higher than student unions or snack bar/cafe´s on healthful entre´es, side dish/salad bar and beverages offerings, but they also had the most barriers to healthful dietary habits (i.e. all-you-can-eat). No differences were found by restaurant type for NEMS-R scores for total restaurant dining environment or healthful entre´es and barriers. Snack bars had more healthful side dishes (P50?002) and fast-food restaurants had the highest level of facilitators (i.e. nutrition information; P50?002). CONCLUSIONS Based on this evaluation in fifteen institutions, the full campus dining environment provides limited support for healthy eating and obesity prevention. The quality of campus dining environments can be improved via healthful offerings, providing nutrition information and other supports to facilitate healthy eating and prevent unwanted weight gain.

Implementation of a Multidisciplinary Team That Includes a Registered Dietitian in a Neonatal Intensive Care Unit Improved Nutrition Outcomes

This study determined whether nutrition outcomes of neonates who were receiving neonatal intensive care were improved with the implementation of a fully functioning multidisciplinary team that included a registered dietitian. A medical record review was conducted of neonates with birth weights of 1500 g or less who were cared for in Sanford Childrens Hospital neonatal intensive care unit from January 1 to December 31, 2001 (prior to functioning multidisciplinary team establishment) and January 1 to December 31, 2004 (subsequent to establishment of a multidisciplinary team). Data from charts in the 2 time periods were examined for differences in nutrition outcomes. Outcome variables included length of stay, birth weight, discharge weight, weight gained for specified time periods, weight at full feeds, weight gain per day, length, head circumference, and number of days to start enteral feeding. Analysis of covariance, controlling for the effect of birth weight, was used to determine differences and was considered significant at P < .05. The mean length of stay (65 days, 95% confidence interval [CI]: 48-68 vs 72 days, 95% CI: 53-73) was not different for the 2 periods. The mean weight at the beginning of enteral feeding was significantly less in the period prior to the establishment of the multidisciplinary team (1099 g, 95% CI: 955-1165 vs 1164 g, 95% CI: 1067-1211, respectively). Weight at discharge, total weight gained, total daily weight gained, daily weight gain from birth to the initiation of enteral feeds, daily weight gain from birth to full feeds, and head circumference growth were significantly greater for neonates in the postgroup than in the pre-multidisciplinary team group. Implementation of a multidisciplinary team that included a registered dietitian improved the nutrition outcomes of low birth weight infants in a neonatal intensive care unit.

Process Evaluation of Project WebHealth: A Nondieting Web-based Intervention for Obesity Prevention in College Students

OBJECTIVE To evaluate the motivational effect of the Project WebHealth study procedures and intervention components on weight-related health behavior changes in male and female college students. DESIGN Process evaluation. SETTING Eight universities in the United States. PARTICIPANTS Project WebHealth participants (n = 653; 29% men). MAIN OUTCOME MEASURES Participants rated motivational effects of study procedures and intervention components. Participants were grouped into outcome-based health behavior categories based on achievement of desired targets for fruit and vegetable intake, physical activity, and/or body weight. ANALYSIS Differences in motivation from each procedure and component were analyzed by gender- and outcome-based health behavior category. RESULTS Women were generally more motivated than men. Compared to those who did not meet any target health behaviors, men with improved health outcomes (68%) were significantly more motivated by the skills to fuel the body lesson, goal setting, and research snippets. Their female counterparts (63%) were significantly more motivated by the lessons on body size and eating enjoyment, and by the suggested weekly activities. CONCLUSIONS AND IMPLICATIONS Specific study procedures and components of Project WebHealth motivated study participants to improve their weight-related health behaviors, and they differed by gender. Findings support the need for gender-tailored interventions in this population.

The Effectiveness of Telemedicine for Weight Management in the MOVE! Program

PURPOSE To examine the effectiveness of videoconferencing technology for delivering comprehensive weight management treatment. METHODS This retrospective cohort study was conducted by extraction of data from medical records for the years 2008-2010. The treatment included a series of 12 weekly MOVE!® classes delivered using videoconferencing. Data were extracted from the time of baseline weight to 1 year after baseline weight for the MOVE! participants (n = 60) and from a concurrent control group (n = 60) that did not participate in MOVE! treatment. FINDINGS Results indicated that the MOVE! group lost weight while the control group gained weight, resulting in a mean difference between the groups of -5.5 ± 2.7 kg (95% CI = -8.0 to -3.0; P < .0001). CONCLUSIONS These results indicate that videoconferencing is an effective method to provide the MOVE! Weight Management Program to veterans. Weight loss was maintained for one year after baseline in the MOVE! group. This is very promising as weight re-gain is a common issue and these results support using videoconferencing for a long-term weight management treatment option.

Development of Young Adults Eating and Active for Health (YEAH) Internet-Based Intervention via a Community-Based Participatory Research Model

OBJECTIVE To develop a tailored, theory-based, Web-delivered intervention to prevent excessive weight gain in young adults using a Community-Based Participatory Research model. DESIGN Investigators from 14 universities developed the intervention and supporting administrative portal using the 4 phases of the PRECEDE model. Steering committees were composed of the target audience (aged 19-24 years) and key health/wellness personnel were formed at each institution and provided information during each phase that was used to guide development of the intervention, Project YEAH (Young Adults Eating and Active for Health). Piloting results were used to refine the curriculum and identify and avoid barriers to delivery. RESULTS Qualitative and quantitative data collected at each phase informed Project YEAH development. In Phase 1, factors of highest priority to young adults were identified. In Phase 2, environmental supports for healthful lifestyles were elucidated. In Phase 3, behavior and environmental changes considered important and changeable were identified. In Phase 4, the 10-week, theory-based, stage-tailored, interactive-learning intervention with a 10-month reinforcement period was developed. CONCLUSIONS AND IMPLICATIONS Applying the PRECEDE model with fidelity during development of Project YEAH resulted in an intervention that pilot participants found relevant and useful, gained attention, instilled confidence in the ability to apply the information, and provided a sense of satisfaction.
