This thesis focuses on ways the Internet can positively influence and educate U.S. Americans to become healthier and eventually lose weight. Throughout the past 30 years, the percentage of overweight and obese adults in the U.S. has increased immensely, resulting in a nationwide epidemic (American Association for Public Opinion Research, 2006; Center for Disease Control, 2006; Goodman, 2005; The Obesity Society, 2008).

Show moreThis thesis focuses on ways the Internet can positively influence and educate U.S. Americans to become healthier and eventually lose weight. Throughout the past 30 years, the percentage of overweight and obese adults in the U.S. has increased immensely, resulting in a nationwide epidemic (American Association for Public Opinion Research, 2006; Center for Disease Control, 2006; Goodman, 2005; The Obesity Society, 2008). The research question for this thesis is the following: What are the perceptions of U.S. adult consumers regarding the positive influence the Internet has on weight loss? In order to determine the influence of the Internet on U.S. adults, a qualitative method of interviewing was conducted with fifteen U.S. adults. Upon completion of listening to the audiotapes and transcribing the health narratives, six key themes emerged as the most relevant to the author's research question: (1) Weight Loss Support Rooted in Social Networking, (2) Internet as an Exercise Motivator, (3) Lack of Trust in Internet Sources for Health Information, (4) Meaningfulness of Health Seeking, (5) Internet as a Teaching Tool, and (6) Uses and Gratifications of Online Health Seeking. Overall, based on this small sample, the researcher concluded that U.S. adults have often turned to the Internet as an aid in their weight loss journey. U.S. adults have a positive perception of the Internet and feel that most adults would benefit from using it to find health information.

Show moreChildhood obesity (CO) is a significant public health issue in the United States, including the immigrant populations. Obese children and adolescents are at increased risk for multiple preventable comorbidities that affect their physical health and psychological well-being. The perception exists that the immigrant child population may possess protection against CO, but this group also experienced an increased prevalence of CO. Acculturation, or the adaptation to American culture and lifestyles, has been shown to be associated with the increased obesity rate among immigrant children and adolescents. Understanding the association between acculturation factors and CO is necessary to effectively combat obesity among children and adolescents in immigrant populations. The purpose of this literature review is to analyze the association of acculturation factors on the prevalence of CO among U.S. immigrant children and adolescents. Only articles that examined CO and at least one aspect of acculturation were included in this review. Twelve articles meeting the criteria were retrieved from CINAHL, Medline, PsychInfo, Academic Search Premier, and ERIC. The review identified the following acculturation factors to be associated with CO: parental immigration factors, child immigration factors, country of birth, generational status and primary home language, parental level of acculturation, and CO related lifestyle practices. There is modest evidence to suggest that a combination of acculturation factors is associated with increasing CO rate in immigrant populations. This review enhances the knowledge and awareness of public and pediatric healthcare professionals to develop targeted interventions that promote healthy weight in immigrant children and adolescents at increased risk for obesity.

Show moreChildhood obesity is a growing epidemic in the United States that has short-term and long-term health consequences for the children affected. Nurses are patient advocates and are responsible for speaking up for the patient; in the pediatric population, a nurse must act as an advocate on behalf of the child. The purpose of this literature review is to look at different barriers to nursing interventions in regard to childhood obesity. A literature review was done by using different databases, with 11 articles having similar themes and interventions used. The main themes from the literature review were parental willingness and involvement in weight loss strategies with their child, a lack of training for nurses in the area of childhood obesity, and a lack of standardized assessment methods for charting and tracking children's weight status. The research suggests that the more involved a parent is, the more successful the child's weight loss will be. Additionally, an overall lack of training in health promotion was noted among nurses alone with a feeling of discomfort when speaking to parents and children about the child's weight, indicating a need for further education in health promotion techniques. Finally, articles did not commonly use a standardized assessment method to track weight status in the pediatric population, making cross-examination of different result difficult and points to a need for a standardized measure that is as objective as possible, such as a body fat percentage measure.

Show moreThe central aim of the present study was to examine the role of expectancies in binge eating behavior. Two distinct statistical techniques were used to accomplish this goal. First, regression analyses were conducted using variables previously identified in the literature, as well as eating expectancies as measured by the Eating Expectancy Inventory (EEI). For both females and males, regression equations including expectancies accounted for a substantial portion of the variance in binge eating behavior. Second, memory modeling techniques were used to model the probable organization of eating expectancies. Memory modeling of hypothetical expectancy networks has lead to successful interventions in alcohol use, and preliminary work in eating revealed a fundamental difference in the way that individuals with high levels of pathology activate and store eating related messages. In the present study, Individual Differences Scaling was used to model the two-dimensional organization of an eating expectancy memory network in relation to binge eating. INDSCAL weights indicated that participants with higher levels of binge eating placed more emphasis on the positive-negative dimension, and examination of group means revealed that high binge eaters expected more change in mood in response to eating. All findings are discussed in terms of implications for enhancing assessment, treatment, and prevention strategies.

Show moreThe objective of this study was to determine the effects of a structured weight loss program that included hypocaloric diet, exercise and dietary supplementation, on weight loss, metabolic syndrome risk factors and antioxidant levels in healthy overweight and obese females. Thirty-seven healthy overweight and obese women (BMI 29.5 ± 2.3 kg/m2, 41.1 ± 7.1 yrs) participated in this study. The subjects were randomized into one of two groups: an exercise, hypocaloric diet and antioxidant supplement (LifePak®; LSANT group, n=20) or an exercise, hypocaloric diet and appetite suppression supplement (HTP Complex® and TēGreen®; LSAS group, n=17). A significant weight loss occurred in both groups after 12 weeks (LSANT: -2.8 ± 2.8 kg and LSAS: -4.3 ± 2.7 kg, p<0.001). Body fat mass, percent body fat, and waist circumference significantly improved in both groups (p<0.05). No significant difference was found between the groups for weight loss (p>0.05). However, a significant difference was found between the groups for body fat mass (LSANT: -1.8 ± 2.6 kg; LSAS: -3.4 ± 2.4 kg, p ≤ 0.05). Glucose, insulin and insulin resistance (HOMA-IR) were significantly decreased in the LSAS group (glucose: -5.0 ± 6.8 mg/dl, p=0.008; insulin: -2.6 ± 3.8 uIU/dl, p=0.013; and HOMA-IR: -0.7 ± 1.0, p=0.012) but not in the LSANT group (p>0.05). There were no significant differences (p>0.05) observed within or between the groups for cholesterol, triglycerides or LDL-c. HDL-c decreased significantly in the LSANT group (-2.9 ± 5.3 mg/dl, p=0.024) but not in the LSAS group (p>0.05). Skin carotenoid scores (SCS) increased significantly within the LSANT group (LSANT: 10950 ± 8395 SCS, p<0.001) but not the LSAS group (p>0.05). Lifestyle intervention that involves a structured hypocaloric diet and increased physical activity results in weight loss and improvements in body composition. However, supplementation with an appetite suppressant (HTP Complex®) did not enhance weight loss beyond what was achieved with a structured lifestyle intervention. Antioxidant supplementation may be of benefit during a weight loss program that incorporates physical activity and a low energy diet.

Recent findings suggest that leptin may be regulated in response to abrupt changes in energy homeostasis. Therefore, it is conceivable that transient changes in energy balance induced by exercise may also regulate leptin synthesis and secretion.

Therefore, it is conceivable that transient changes in energy balance induced by exercise may also regulate leptin synthesis and secretion. As such, we hypothesized that acute increases energy expenditure (i.e. exercise), may regulate leptin concentrations in obese individuals. Fifteen healthy obese males underwent either a single exercise session of moderate intensity (58.4 % ± 4.0 of VO2max) for 60 min (n=8), or served as controls (n=7). The exercise session elicited an energy expenditure of 567±80 Kcal. No significant changes in plasma leptin (pre 23.5± 30.2; post 24.3± 34.3; 24h-post 34.9± 66.6; 48h-post 33.8±64.0 ng/ml), or insulin levels (pre 16.1± 9.2 vs. post 8.1± 9.1; 24h-post 14.3± 9.9; 48h-post 13.8± 10.2 ?U/ml) were detected immediately after the intervention. Baseline plasma leptin levels were positively correlated with BMI (r=0.65; p<0.01), body weight (r=0.64; p<0.01), % body fat (r=0.90; p<0.01) and were negatively correlated with VO2max (r=-0.82; p<0.01). The results of the present study suggest that acute exercise of moderate intensity and duration may not affect leptin concentration.

Head Start Performance Standards requires that the children have free access to drinking water throughout the program day (DHHS, 2016a).The first goal of this study was to identify the quantity of water consumed by children during the program day (8am-2pm). This study employed a person-centered approach to explore the water consumption of the children through observations and direct measurement to identify the amount of the water consumed during a program day. Four classrooms from a Head Start center in a southeastern school district were included in the study. A total of 80 children were observed during the program day (8am-2pm) over a period of 8 weeks. Each child was given a water bottle and instructed to drink freely from the water fountain or the water bottle. In the classroom, water intake from the water fountain and water bottles were recorded.The second goal of this study is to examine profiles of the water consumption from both the school and at home. A person-centered approach combined the individual data of water consumption, from both observation and parental reports, to deepen our understanding of the issue. The 80 parents or legal guardians completed a brief survey to provide information on water consumption at home. No statistically significant differences across demographic characteristics were found. However, large to moderate effect size were discovered.The third goal of the present study was to compare the usage of the sugary sweetened beverages (SSBs) with the national Head Start Faces data 2009 (DHHS, 2017). The current study group had statistically significant difference in consumption of those sugary sweetened beverages. The current study concluded that the water consumption of the children in Head Start classrooms are far less that recommended level. Suggestions on how to increase water consumption were made based on observed behaviors of children across four classrooms. Policy changes regarding water consumption is suggested to increase the water consumption.

Show moreApproximately one-third of children in the United States are overweight or obese with increased risks for numerous physical and psychosocial comorbidities. Schools are ideal environments to address this serious health crisis and school nurses are uniquely positioned qualified healthcare providers to actively participate in childhood obesity prevention (COP). A review of the literature provided findings to identify a gap in the knowledge regarding the association between school nurse COP perceptions and practices. A modified theoretical framework based on Bandura's health promotion by social cognitive theory guided this study. The purpose of this study was to identify the key perceptions (self-efficacy, perceived benefits and perceived barriers) influencing school nurse participation in COP practices and determine associations between school nurse characteristics and COP perceptions and practices. Preliminary research was conducted to determine content validity for modified perception scales, clarity of instructions and questions, data collection and retrieval procedures, and refinement of recruitment strategies. Adequate reliability and validity was determined for modified scales measuring school nurse self-efficacy, perceived benefits, perceived barriers, and COP practices targeting individual children (child-level) and the entire school population (school-level). Florida RN school nurses (n = 171) completed self-administered anonymous questionnaires from an emailed weblink or a paper version offered at two Florida Association of School Nurses conferences. School nurses with characteristics reflecting more education engaged in more COP practices (p (<) .05) than those without education-related characteristics. School nurses with (>) 8 hours of COP education reported higher COP self-efficacy than those with none (p (<) .01). Linear regressions showed that a model comprised of self-efficacy, perceived benefits, and perceived barriers significantly explained 12.0% of the variance in child-level practices (p (<) .001) and 9.1% of school-level practices (p (<) .001). Self-efficacy explained the most variance of school nurse child-level and school-level practices (p (<) .001), and perceived barriers were inversely associated with child-level practices (p (<) .05). Four series of regressions showed that only perceived barriers partially mediated the influence of self-efficacy on child-level practices. Data analyses indicated self-efficacy and perceived barriers were key determinants of school nurse COP practices. Therefore, policy changes and educational interventions to increase self-efficacy and reduce perceived barriers may be effective in mobilizing school nurses to actively engage in COP practices.

Show moreChildhood obesity is a global health concern that puts children at risk for developing serious health complications. With increasing rates worldwide, it is important to determine how to decrease its prevalence and promote prevention in future generations. Emerging evidence indicating that pre-pregnancy weight status and/or gestational weight gain (GWG) may be linked with overweight/obesity in children. Much of this body of research focused on weight status of offspring at birth and at preschool age. The purpose of this study is to: (1) analyze the research findings regarding obesity in children 5 to 18 years and their mother's pre-pregnancy weight status and/or GWG, and (2) make recommendations for prevention based on a review of current research. A database search of CINAHL, Medline, ERIC and PsycInfo was conducted. A total of 14 articles were identified based on their relevance to key search terms and meeting criteria. This literature review indicated support for associations between an underweight/overweight/obese pre-pregnancy weight status combined with greater than recommended total GWG and higher overweight/obesity in older children and adolescent offspring. Findings also supported the associations between pre-pregnancy weight status with high GWG during early pregnancy and increased offspring overweight/obesity. Pre-pregnancy overweight/obese weight status of mothers was the single factor consistently found to be strongly associated with risk for overweight and obesity in children 5 to 18 years of age. Results of this review support the need for further education, interventions, and policies aimed at healthy nutrition for women during and prior to pregnancy to prevent childhood obesity.

Stigmatization of the obese has tremendous social and economic costs both for the stigmatized population and for society as a whole. Few studies have been done to show effective ways to reduce obesity bias. This study looked to expand the research on effective ways to reduce obesity bias. Using a between-participants experimental design, the present study investigated whether multi-faceted information content about the causes of obesity (including psychological, social, and physiological causes) would be more effective in reducing obesity bias than any one of these causes presented alone. Results showed that participants' evaluations of a target woman who was overweight did not differ between the information content conditions, nor did they differ from a control condition. Implications, as well as limitations in the current study, are discussed.

Show moreMonocyte chemotactic protein-1 (MCP-1) plays a critical role in the development of cardiovascular diseases. How MCP-1 contributes to the development of heart disease is not understood. We present evidence that MCP-1 causes death in cardiac myoblasts, H9c2 by inducing oxidative stress, ER stress and autophagy via a novel Zn-finger protein, MCP-1 induced protein (MCPIP). MCPIP expression caused cell death and knockdown of MCPIP, attenuated MCP-1 induced cell death. Expression of MCPIP resulted in induction of iNOS and production of reactive oxygen (ROS). It caused induction of NADPH oxidase subunit phox47 and its translocation to the cytoplasmic membrane. Oxidative stress led to the induction of ER stress markers HSP40, PDI, GRP78 and IRE1α. ER stress lead to autophagy as indicated by beclin-1 induction, cleavage of LC3 to LCII and autophagolysosome formation. Here, MCPIP-induced processes lead to apoptosis as indicated by caspase 3 activation and TUNEL assay. This cell death involved caspase 2 and caspase 12 as specific inhibitors of these caspases prevented MCPIP-induced cell death. Inhibitors of oxidative stress inhibited ER stress, and cell death. Specific inhibitors of ER stress inhibited autophagy and cell death. Inhibition of autophagy inhibited cell death. Microarray analysis showed that MCPIP expression caused induction of a variety of genes known to be involved in cell death. MCPIP caused activation of JNK and p38 and induction of p53 and PUMA. These results collectively suggest that MCPIP induces ROS/RNS production that causes ER stress which leads to autophagy and apoptosis through caspase 2/12 and IRE1α –JNK/p38-p53-PUMA pathway. These results provide the first molecular insights into the mechanism by which elevated MCP-1 levels associated with chronic inflammation may contribute to the development of heart failure. A role for inflammation and MCP-1 in obesity and diabetes has been implicated. Adipogenesis is a key process involved in obesity and associated diseases such as type 2 diabetes. This process involves temporally regulated genes controlled by a set of transcription factors, C/EBPβ, C/EBPδ, C/EBPα, and PPARγ. Currently PPARγ is considered the master regulator of adipogenesis as no known factor can induce adipogenesis without PPARγ. We present evidence that a novel Zn-finger protein, MCPIP, can induce adipogenesis without PPARγ. Classical adipogenesis-inducing medium induces MCP-1 production and MCPIP expression in 3T3-L1 cells before the induction of the C/EBP family of transcription factors and PPARγ. Knockdown of MCPIP prevents their expression and adipogenesis. Treatment of 3T3-L1 cells with MCP-1 or forced expression of MCPIP induces expression of C/EBPβ, C/EBPδ, C/EBPα, PPARγ and adipogenesis without any other inducer. Forced expression of MCPIP induces adipogenesis in PPARγ-/- fibroblasts. Thus, MCPIP is a newly identified master controller that can induce adipogenesis without PPARγ. Heart failure is a major cause of death in diabetic patients. Hyperglycemia is a major factor associated with diabetes that causes cardiomyocyte apoptosis that leads to diabetic cardiomyopathy. Cardiomyoycte apoptosis is a key event involved in the pathophysiological progression of diabetic cardiomyopathy. We have recently found that in ischemic hearts, MCP-1 can induce the zinc-finger protein, MCP-1 induced protein (MCPIP) that causes cardiomyocyte apoptosis. Although there is evidence that inflammation may play a role in diabetic cardiomyopathy, the underlying mechanisms are poorly understood. In this study, we show that treatment of H9c2 cardiomyoblasts and Neonatal Rat Ventricular Myocytes (NRVM) with 28mmol/L glucose concentration results in the induction of both transcript and protein levels of MCP-1 and MCPIP. Inhibition of MCP-1 interaction with CCR2 via specific antibody or with the G-coupled receptor inhibitors propagermanium and pertussis toxin attenuated glucose-induced cell death. Knockdown of MCPIP with specific siRNA yielded similar results. Treatment of cells with 28mmol/L glucose resulted in increased ROS production and phox47 activation. Knockdown of MCPIP attenuated these effects. The increased ROS production observed in H9c2 cardiomyoblasts and NRVM's resulted in increased ER stress proteins GRP78 and PDI. Knockdown of MCPIP attenuated expression of both GRP78 and PDI. Inhibition of ER stress with TUDC and 4'PBA prevented high glucose-induced cell death death. Treatment of cells with 28mmol/l glucose resulted in autophagy as determined by an increase in expression of beclin-1 and through increased cleavage of LC3I to LC3II. Knockdown of MCPIP attenuated expression of beclin-1 and prevented cleavage of LC3. Addition of the autophagy inhibitors 3'methyladenine and LY294002 attenuated high glucose-induced H9c2 cardiomyoblast death. We conclude that high glucose-induced H9c2 cardiomyoblast death is mediated via MCP-1 induction of MCPIP that results in ROS that leads to ER stress that causes autophagy and eventual apoptosis.

Community and university individuals (N = 347) who are or previously were overweight completed self-report measures of thought suppression, weight history, and eating behaviors. Suppression of specific thoughts about food/weight/shape was related to weight cycling, binge eating, and food cravings. Participants who believed thoughts of food lead to eating were more likely to attempt suppression of food-related thoughts. Results have implications for improving weight loss maintenance and support further exploration of third wave interventions, such as Acceptance and Commitment Therapy and Mindfulness, in the treatment of obesity.

Show moreThe present study examined archetype theory (Marcus (&) Fritzsche, 2015) that suggests that the intersection of multiple group memberships will create a unique cognitive representation, as it is relates to sex, age, and weight. Following a pilot study to equate photos on attractiveness, perceived competence, professionalism, and intelligence, 183 participants reviewed a fictitious LinkedIn profile in which all information was held constant across participants except the photo. Using a 2 (sex) x 2 (age) x 2 (weight) design (manipulated through the photos), participants rated the job applicant on adjectives associated with proposed sex, age, and weight archetypes and on perceptions of job suitability. Results showed that the most young, overweight female received the highest ratings on negative adjectives (i.e., lazy, uncontrolled, self-indulgent) and was rated lower than most conditions on job suitability. Overweight conditions received lower ratings on job suitability than their average-weight counterpart. Weight also impacted the old, female, such that the old, overweight female received lower ratings than her average-weight counterpart on job suitability. In order to help individuals who face disadvantages and unfair treatment in the workplace, the negative effects multiple-group membership has on certain groups must first be acknowledged.

Show moreObesity is a condition affecting billions of people around the world. Its societal, psychological, and health outcomes have been well documented across multiple disciplines. Moreover, obesity leads to serious workplace outcomes for the organization, the obese individual, and the coworkers working around the obese employee. With this multi-chapter dissertation, I review the literature on the workplace consequences of obesity and extend one potentially fruitful area within this literature base: obesity's impact on a proximal employee.Chapter 1 reviews the workplace consequences associated with obesity. The purpose is to evaluate and integrate this multidisciplinary literature so that management scholars can take up the study of obesity. Although a limited amount of work is being done in management, this work is stagnant and ignoring the larger body of literature from other areas. Addressing this weakness, this chapter accomplishes three goals. First, it reviews the empirical literature and conceptual foundations that have examined the workplace consequences of obesity. Second, it develops an integrated conceptual model of obesity's impact on workplace outcomes, with particular attention to the processes by which obesity is associated with these outcomes. Third, it presents key unanswered questions and directions for future research.Chapter 2 explores a new target for the impact of obesity, the non-obese coworker working around the obese employee. This chapter considers how an employee's obesity can affect a proximal coworker's job performance. To do so, it considers the three people: an observer (Person A), an obese employee (Person B), and a non-obese coworker (Person C). To date, the main theoretical framework has only considered ratings in the mind of an observer (Person A) and how the negative attitudes associated with obesity (Person B) can spill over onto a proximal worker (Person C). This leads an observer (Person A) to rate the coworker's (Person C) performance more negatively than a coworker not working around an obese employee (Person B). However, beyond the impact of obesity on the subjective evaluations by an observer (Person A), there is reason to believe that the non-obese employee (Person C) may be impacted in such a way to affect actual job performance. Accordingly, I competitively test three theoretical perspectives that may explain the processes by which a coworker's obesity (Person B) may impact a proximal coworker's (Person C) job performance. One of these perspectives (stereotype activation theory), receives consistent support across samples.Chapter 3 presents a concluding discussion. I consider lessons learned from Chapter 2 and integrate these with the literature reviewed in Chapter 1.

Show moreOverweight and obese children have increased risks for multiple preventable diseases and conditions which can impair their physiological health and significantly increases the overall cost of their healthcare. Free mobile applications and technology for weight loss, dietary tracking, and physical activity may be quite useful for monitoring nutritional intake and exercise to facilitate weight loss. If so, nurses are well positioned to recommend such tools as part of their efforts to prevent childhood obesity and help children and parents better manage childhood obesity when it is present. However, there are no guidelines that nurses can use to determine what applications or technologies are most beneficial to children and their parents. The purpose of this project is to develop such guidelines based on a review of the scientific literature published in the last 5 years. Articles regarding healthy-lifestyle promoting mobile applications and technological approaches to health and fitness interventions were identified by searching articles indexed by CINAHL, Psychinfo, Medline, ERIC, IEEE Xplore, and Academic Search Premier. Identified articles were assessed using Melnyk's hierarchy of evidence and organized into tables so that implications for research and suggestions for practice could be made.

Show moreChildhood obesity is a foremost concern throughout the health care community. Approximately 17.6% of the pediatric population meet the criteria for obesity, which can lead to health disparities later in life, such as hypertension, type 2 diabetes mellitus, and metabolic syndrome. Emerging mobile and wearable lifestyle tracking devices can be a viable solution to the challenging problem of childhood obesity through behavior changes, feasibility, and adherence. The purpose of this literature review was to determine the effect that mobile and wearable activity tracking devices have on the obese pediatric population. A centralized review of the literature was conducted using various data basesand resulted in 19 articles. 5 articles were chosen to review in more detail. 13 other articles were hand searched through credible resource citations, rendering 14 articles that met all criteria. The three general themes found in this literature review suggest that wearable activity tracking devices can be designed and effectively used by the pediatric population. Also, wearable activity tracking devices are accurate in conveying information on physical activity, calories, and heart rate. Lastly, wearable activity tracking devices can initiate behavioral changes in children leading to an increase in physical activity, resulting in the prevention and treatment of pediatric obesity.While in a majority of the studies analyzed trails were short. The research suggests wearable activity tracking devices will produce the desired results of increased activity in pediatric populations when they are worn correctly, are adequately engaging, and when they are designed in a feasible manner that is appealing to children.

Show moreThe prevalence of overweight and obese children has increased dramatically in the United States over the past 20 years and is a symptom of multiple systemic and cultural changes that have significantly influenced alterations in energy intake, energy expenditures, and the energy balance of children across the nation. School-based obesity prevention programs addressing nutrition and healthy eating behaviors within the school environment and cultural context provide a unique opportunity to educate and engage students in healthy food consumption practices. This study evaluated the effectiveness of a three-year elementary school nutrition education program for students in grades kindergarten through fifth using a longitudinal analysis of two separate data sets, a nutrition skills behavior assessment survey of self-reported eating behaviors, and body mass index (BMI) scores derived from height and weight measurements of program participants. Nutrition survey results indicated that students reported making healthier food choices from August 2001 to November 2004, with a significant decrease in reported consumption of fats/oils/sweets and significant increases in reported consumption of milk, meat, vegetables, fruit and grains. BMI results indicated a 7.8% decline in the percentage of students in the "overweight" and "at-risk for overweight" categories between August 2001 and October 2004. The combined results of both measures indicate that the nutrition education program appeared to positively affect eating behaviors and body mass index percentages. Implications of the study and strategies for further research are proposed.

Show moreChildhood obesity is a prevalent problem in the United States. Obesity increases the risk for many diseases. Obese children are likely to become obese adults with additional comorbidities. Studies have reported mixed findings regarding associations between reading nutrition labels and improved dietary behaviors/healthy weight status. The purpose of this study is to determine whether the frequency of children reading nutrition labels is related to frequency of performing 12 dietary behaviors. De-identified baseline data from a previous quasiexperimental pilot study were analyzed. Data were collected from 4th and 5th graders (n = 42) at an after-school program. An adapted paper survey was administered to the children to measure the number of days (0�7) they read nutrition labels and performed 12 dietary behaviors over the preceding week. Due to non-normal distribution of data, non-parametric Spearman rho correlations were conducted to determine relationships between frequency of reading nutrition labels and dietary behaviors. Positive correlations were found between frequency of reading nutrition labels and eating fruit for breakfast; eating vegetables at lunch/dinner; eating whole grain/multigrain bread (p less than .05); eating fruit for a snack; eating vegetables for a snack (p less than .01). Frequency of reading nutrition labels was inversely related to drinking soda/sugar-sweetened beverages (p less than .05). Significant relationships were found between frequency of reading nutrition labels and several dietary behaviors associated with childhood obesity prevention. Findings are promising and support the need for further intervention research to determine potential direct influences of children reading nutrition labels on dietary behaviors.

Show moreWith obesity in adolescents becoming a major health problem in the United States, there has been an expansion in the use of nutritional education programs as intervention. Effective nutrition education can decrease the incidence of obesity and other diet-related chronic diseases, type-2 diabetes, cardiovascular disease, and hypertension. This dissertation in practice proposes to design a nutrition education program, integrating farm and culinary activities into a nutrition education curriculum. The program is designed as a stand-alone program, but for this practice, implementation integrates the nutrition education program into the Film @ 6 after-school program (-) a STEM-focused program designed to assist sixth graders in their first year of middle school (-) at Southeast Middle School in Salisbury, Rowan County, North Carolina (NC). This experiential nutrition education program will provide instruction and activities in order to increase nutritional knowledge, improve culinary techniques, and increase consumption of fruits, vegetables, and minimally processed foods of sixth grade students as a means to address the overweight and obesity risks of middle school children. Children and adolescents are considered the priority population for intervention strategies because 70% of obese adolescents become obese adults and it is difficult to reduce excessive weight once established (Dehghan, Akhtar-Danesh, (&) Merchant, 2005).

Show moreThe current study evaluated the initial feasibility, efficacy, and acceptability of a motivationally-tailored family-based intervention designed to promote the adoption of healthy lifestyle behaviors associated with physical activity and nutrition. Parents (N=132) of children 6 to 11 years old were randomly assigned to the intervention or control condition, and they completed a series of online questionnaires. Intervention participants (n=61) received a single motivationally-tailored feedback report via e-mail. Control participants (n=71) completed measures and immediately received information about a free online resource that provides information about healthy lifestyle behaviors (www.mypyramid.gov). Feasibility data indicate that an online feedback program has high dissemination potential (parents from 31 states participated). However, the current methodology is not sufficient in reaching families who are at greatest risk for developing chronic health conditions associated with obesity or low activity level. In general, the intervention was acceptable to parents. Outcome data revealed that the intervention and control groups did not differ significantly on most variables at one month follow-up. Exploratory analyses provided additional evidence for the importance of including parents and targeting parent-child interactions in the context of pediatric nutrition and physical activity interventions. Limitations and future directions are discussed.
