To evaluate the effectiveness of the weight loss initiative, university of Arkansas at Pine Bluff obesity prevention intervention based on the Dietary guideline for American of approach, on the improvement of body weight, A 12 -month study completed by focused on interventions to improve physical activity and health through walking teams led by supportive coaches, self-monitoring, and monthly nutrition and physical education sessions involved regular aerobic, strength training, and stretching based on the Trans theoretical model. Of 80 participants 10% were normal weight, 22% were overweight, and 57% were obese. Ninety-nine percent were African American and 97% were women. The average age was 21 years. Results indicated that documented from the beginning to the end of the intervention season indicated that (58%) of the original students who returned for follow-up assessments had a weight loss was 5% in 52% of the students, weight gain in 6% in 18% of the students. Significant weight loss was 10% in 11% of the students, it was not significant weight loss was 2% in the 19% of the students with during intervention 12 months season (p<.0001). Multicomponent university students obesity intervention effectively program may need further more research.
Currently more than 65% of American adults are overweight or obese, making improvements in this area arguably one of the most important health challenges of our time. Most obesity research to date has focused on biomedical aspects rather than on the importance of diet and physical activity behaviors in maintaining a healthy body weight. There is a need to identify new strategies that will enhance adherence to the healthful food and physical activity patterns set forth in the Dietary Guidelines for Americans, 2005 (DG). There is also a need to adapt established DG eating patterns, for the Lower Mississippi Delta population and to test their effectiveness in preventing obesity and related diseases. Minimal research has addressed sustained prevention and intervention strategies to prevent obesity and related diseases for African Americans, especially college/university students [1-6].
The increase in obesity is moving steadily away from the Healthy People 2010 goals of 15% prevalence of obesity in adults and 5% prevalence in children. Overweight continues to be a serious health concern for children, adolescents and young adults and is a leading predictor of obesity in adulthood increasing the prevalence of chronic illness [7-10]. The American Dietary guidelines were designed to improve the dietary and physical activity patterns of all Americans. However, research conducted found that participants' knowledge of the 2000 DG was lacking in the areas of food composition, healthier eating, and the relationship between diet and health, and food labels . Since 2000, evidence of the public’s understanding, perception and exposure to the 2005 recommended the American dietary guideline remains elusive in the literature. Additionally, as many as 90 million Americans lacked basic skills needed to access, understand, and use health information and services to make healthy dietary choices . However, research has documented knowledge of the DG by college/university students and Americans and has found nutrition literacy to be less than adequate [11,12].
African Americans have the widest deviance from the current nutritional guidelines compared with non-Hispanics whites, and raises the question of why African-American (non-Hispanic Blacks) eating patterns have not equilibrated with mainstream eating pattern after so many generations . In many instances, culturally familiar ways of eating are defined as “barriers” and viewed as “non-adherent.” Essential motivators of eating patterns, such as flavor, price, tradition, and emotional and social meanings, should not be ignored or devalued in dietary guidance but considered essential in minority groups .
Researchers have found that despite the poor eating habits that manifest in college, the overall mean caloric intake in college freshmen may actually decrease [14-16]. Yet at the same time, body weight tends to increase during the college years, suggesting that physical activity must also be decreasing during the transition from high school to college . Intervention programs directed towards college/university students focused primarily on strategies intended to decrease the body weight, through behavioral counseling, nutrition education without physical activity, or decreased or modified dietary intake with or without physical activity [18-21]. Although these studies addressed dietary interventions, the majority found that physical activity and lifestyle were important determinants in the outcomes. students attending the University of Kansas, Lawrence, were overweight and engaged in less than healthy dietary habits, such as low fruit and vegetable intake, low fiber intake, and low physical activity, suggesting the need for greater attention to diet and exercise interventions in this population. More importantly, the findings suggested that physical activity levels may decrease as students become older . In comparison, study participants who started the National Heart, Lung, and Blood Institute’s Growth and Health Study at ages 9-10 years had a significant decline in physical activity by ages 18-19 . Similarly, the greatest deterioration in physical activity has been observed between the ages of 15 and 18 years, and a continuous decline is common between 18 and 29 years of age . Overall, the most significant finding was a decrease in physical activity. In some studies students did not have an increase in caloric intake but gained weight. Issues that motivated the student’s decision to decrease physical activity need further attention.
A nutrition education program without physical activity that addressed issues, such as a personal diet plan based on an appropriate calorie level, label reading, behavior change techniques, and portion control using the Plate Model to design healthy meals that fit their meal plan . The importance of exercise is only discussed in this program. A student not demonstrating success was offered behavioral counseling. Effectiveness of the program was evaluated through nutrition knowledge pre-test and post-test relevant to the nutrition content areas. The premise of this program is that an increase in nutrition knowledge and skill development will contribute to a healthier final 24-hour dietary recall when compared to the first recall. Effectiveness of these interventions were not discussed; however, the university offers specific interventions for obesity as a part of services students commonly receive, i.e., meals, transportation, lab fees, which may be an option for other colleges/universities.
The African-American women who are overweight may not perceive themselves to be overweight; increasing the importance of what role image has in weight maintenance . Image is extremely important for this age group and may have a significant influence in their decisions to participant in physical activity. Socially acceptable forms of physical activity may be fewer for women than men, particularly in some ethnic groups. Social concerns may include how exercise affects one’s hairstyle or image of femininity, as well as the possible displeasure of spouses or other household members, because exercise may be perceived as taking a woman away from family responsibilities [23,24].
Another risk factor associated with overweight and obese in college/university students postulated by Desai et al. (2008) is disordered eating . The author notes that although the eating behaviors leading to obesity are not technically considered disordered eating behaviors, it is important to note that overweight individuals do exhibit disordered eating symptoms, such as feelings of ineffectiveness, perfectionist attitudes, low introspective awareness, low self-esteem, emotional eating, and depressive symptoms. These psychological concerns have implications for the treatment of overweight in that a simple dietary intervention or physical education course may not be sufficient to generate a sustainable reduction in young adult overweight and obesity. The study conducted by Desai et al.  found that overweight and obesity are associated with distorted eating behaviors and perceptions. Specifically, a preoccupation with food, feeling that food controlled one’s life, the desire to be thinner, and bingeing and dieting behaviors were all positively associated with overweight and obesity. This study was evaluate the effectiveness of the weight loss initiative, university of Arkansas at Pine Bluff obesity prevention intervention based on the Dietary guideline for American of approach.
Participants was recruited through university Arkansas at pine bluff to the development of the program, to collect baseline data that was analyzed and used to develop the “Eating to Live” program. Participants (80) of interview was developed that includes questions that elicit strategies, perceptions, and concerns related to the topics and activities to be used in developing the “Eating to Live” curriculum and ultimately the intervention. Questions was elicit perceptions and attitudes .The participants’ interview was allowed the researchers to gather information from more than one person in less time. This approach also provides checks and balances that weed out false or extreme views. An incentive of $20 per person was paid to each participant participating in each session. The participants were address dietary and physical activity patterns, knowledge of the food groups, food labels, American Dietary Guidelines for Americans, 2005.
Dietary records was proposed during the intervention only. Although they was more extensive, the participant was record the foods and beverage and the amounts of each consumed over 3-4 days. The meal was recorded at the time of the eating occasion. This was done online monkey service. The participants was asked to take a picture of the meals eaten (breakfast, lunch and dinner). The dietary record method has the potential for providing quantitatively accurate information on food consumed during the recording period. Information needed for the Plate Model module was collected by photographs (via cell phone or digital cameras) of foods eaten by the participants to document current eating patterns. The photographs was used to validate the information collected in the recalls and records; i.e., food combinations, and portion sizes, amount of fat, carbohydrate, vegetables, and proteins consumed [22, 25]. Participants was using cell phones was send data to investigators by email, or an internet computer download site. These photographs was potentially represent culturally relevant meals for this population and was used in developing the educational content to be used in the intervention. Meals from menus based on the American dietary guideline, prepared by the Department of Human Sciences and UAPB cafeteria, was tasted by the participants to test acceptability in order to better understand how the American dietary guideline was adapted for this intervention.
The “Eating to Live” program was a culturally adapted 12-month weight loss intervention designed based on adoption of the American dietary guidelines 2005, This programs was enhanced with adapted DG recommendations and strategies, based on the baseline data collected from group interviews, 24-hr dietary recalls, the current plates of food consumed by the students, photographs of the current meals and surveys of the ‘’food availability’ environment. The current plates of food consumed was analyzed for combination of foods and portion sizes, Photographs of food combinations and portion sizes was used to modify the food plates based on recommendations in the American dietary guideline. Modified food plates was compared to the American dietary guideline recommend.
Participants in the initial phase were asked to complete four 24-hour dietary recalls over a period of 2 weeks (two per week). Foods and beverages in the preceding 24 hours or in the preceding day was recorded by the investigator (dietitian) to clarify discrepancies or probe for forgotten foods or meals. The 24-hour recalls was use standard protocols for the Nutrition Data System for Research (NDSR); DSAM systems (software, version 4.06). The NDSR was used to analyze the 24-hour recalls used in the development phrase because there was a lower respondent burden than dietary records, which was used in the intervention. The NDSR protocol uses a multiple pass approach to reduce underreporting and to assist further standardization of the interviews. Data was collected by a nutritionist certified as a NDSR trainer (Nutrition Coordinating Center 2008). Qualitative data were analyzed using NVivo7 software to find patterns in the data, and enable the researchers to display and analyze relationships in the data. Individual’s eating and physical activity patterns was compared to the American dietary guideline recommendations.
A 12 -month study completed by focused on interventions to improve physical activity and health through walking teams led by supportive coaches, self-monitoring, and monthly nutrition and physical education sessions involved regular aerobic, strength training, and stretching based on the Trans theoretical model . Of 80 participants 10% were normal weight, 22% were overweight, and 57% were obese. Ninety-nine percent were African American and 97% were women.

Significant weight loss was 10% in 11% of the students, it was not significant weight loss was 2% in the 19% of the students with during intervention 12 months season (p<.0001).Conclusions: A 12-month multicomponent school-based obesity intervention program may be effectively used to decrease body weight
During behavior intervention, we were using the conceptual framework guiding the development and delivery of the intervention was the Trans theoretical Model also known as the stages of change model (26). This model emphasizes behavior change as an individual move through the stages of readiness of change: pre-contemplation (not thinking about changing in the next 6 months), contemplation (thinking about changing within the next 6 months), preparation (intending to take action in the near future, usually 1 month), action (specific changes have been made), and finally maintenance (working to prevent relapse). Determination of individual readiness for change was evaluated using a forced-choice questionnaire based on the stages of the change process. The application of the Trans theoretical Model (26) was similar to the Health Stages program for older adults used. As in Health Stages, the Eating to live program has several components: a) a comprehensive curriculum, b) an implementation strategy, and c) a program evaluation. TTM is the organizing concept for the program/intervention and the TTM concepts was integrated into program planning, curriculum development, and program evaluation. Program planning: According to TTM, people are in different stages of readiness to change any given health behavior. As a result, different types of information and interventions was needed for people who was in different stages. For example, people may be in maintenance for one behavior, like exercise, but in Contemplation for eating a low fat diet. The TTM encourages the researcher to develop a variety of ways to reach out to the participants. Staging of the participants for health behaviors provides a way to target needed interventions to the participants.
To assess the effectiveness of this obesity prevention intervention program using the dietary guideline for American approach in decreasing overweight at a period of 12 months among university students. Our study finding confirmed necessity of school building-level implementation of the intervention, showing some of a significant improvement in students' health status and healthy behaviors. Given a significant role of schools due to an efficient accessibility to a variety of resources intervention implementation at level of individual to better tailor the intervention programs and take ownership over planning programs more fit to their students' needs, leading to more promising outcomes in health promotion. The findings of the present study strengthen that an intervention which is committed to making school environments conducive to students' healthy behaviors and changing students' individual behavior and norms may help students maintain or reduce their overweight over a relatively long time span.
Limitations of this study should be noted. First, a single measurement on a single occasion may be susceptible to measurement errors. Second, although biometric data such as height, and weight were objectively measured at each data collection point for the entirety of participants, behavioral measures were collected using surveys. Thus, self-reports on behavioral measures might have confounded study findings. Despite these limitations, This study was evaluate the effectiveness of the weight loss initiative, university of Arkansas at Pine Bluff obesity prevention intervention based on the Dietary guideline for American of approach may be effectively used to decrease body weight. Further investigation would be warranted to evaluate effectiveness of multicomponent intervention program to a targeted population for efficacy of the desirable no pharmacological treatments for university students to maintain healthy weight.
