Objectives: Although childhood obesity has received growing attention, parents still fail to recognize overweight and obesity in their children. Accurate identification of overweight or obesity in their child is associated with the parent's responsiveness to interventions aimed at preventing weight-related health issues. Recent research shows that a child's age and gender are associated with parental misperception of their child's weight status, but little is known about the interaction of these factors across various age groups. This study examined the association between a wide range of parent, child, and household factors and the accuracy of parental perception of their child's body weight status compared to parent-measured body weight status. Methods: Data were collected from a random-digit-dial telephone survey of 1708 households located in five low-income New Jersey cities with large minority populations. A subset of 548 children whose parents completed the survey and returned a worksheet of parent-measured heights and weights were the focus of the analysis. Bivariate and multivariate analyses were performed to determine the factors significantly associated with parental perception of their child's body weight status. Results: Based on parent-measure heights and weights, 36% of the children were overweight or obese (OWOB). Only 21% of OWOB children were perceived by their parents as OWOB. Child gender, child body mass index (BMI) and parent BMI were significant independent predictors of parents' accuracy at perceiving their child's body weight status. Conclusion: Boys, OWOB children, and children of OWOB parents had significantly greater odds of parental underestimation of their body weight status. Parents had better recognition of OWOB in their daughters, especially older daughters, than in their sons, suggesting parental gender bias in identifying OWOB in children. Further research is needed regarding parental gender bias and its implications in OWOB identification in children.

Although many studies have looked into the benefits and consequences of consuming breakfast, most have not looked into the unintended consequences of breakfast being served at school; specifically the consumption of an additional breakfast. This cross-sectional study investigated the prevalence and health related outcomes of the consumption of an additional breakfast at school amongst youth using a survey assessing possible predictors (i.e. parental education, morning activities, race), the ASA-kids 24-hr dietary recall, and height and weight measurements. A total of fifty-eight participants (aged 13.5±1.6 years; 55.2% male) were recruited at after school library programs and Boys and Girls Clubs in the Phoenix, Arizona Metro Area during 2014. The main outcomes measured were BMI percentile, total calories, iron, sodium, carbohydrates, added sugar, and fiber. In the study, the prevalence of consumption of an additional breakfast at school at least once a week or more was 32.7%. There were no significant differences between the consumption of an additional breakfast and not an additional breakfast amongst the main outcomes measures. The directionality of the relationship between the consumption of an additional breakfast and overweight/obesity amongst youth was inverse (OR = 0.309; p-value = 0.121), but this was not significant. This study found that the consumption of an additional breakfast at school is not contributing to overweight/obesity in youth, nor does it alter overall caloric and nutrient intake. School breakfast programs are important for providing breakfast and key nutrients to youth.

While obesity rates have plateaued within the last decade,

two-thirds of the United States

population is currently classified as overweight (defined a

s a body mass index [BMI] of

25-29.9 kg/m²) or obese (a BMI greater than 30 kg/m²). Bariatric

surgical interventions

are not only more effective than behavioral treatments

in the short term but are the only

form of obesity intervention with evidence of consisten

t long-term effectiveness.

However, even among bariatric surgery patients, weight

loss often stabilizes and it is

estimated that more than 20% of bariatric surgery patient

s will regain a significant

amount of weight that was initially lost long-term. Li

ttle research to date has been

conducted on physical activity in post bariatric surgery pati

ents. More specifically, there

have been no studies to date examining the effects of Me

ditative Movement (MM)

programs on body composition in bariatric patients. A s

tudy using an 8-week Tai Chi

Easy program was conducted in female gastric bypass patient

s to explore feasibility of

MM in the bariatric population as well as pre- and post-in

tervention changes in weight,

mindfulness, eating behaviors, body awareness, physical a

ctivity patterns, dietary quality

and mood. Data analysis revealed that there were no s

ignificant changes in weight or

physical activity patterns; however, significant changes w

ere observed in anxiety, overall

body awareness and cognitive restraint in eating. Addit

ionally, a significant decrease in

processed meat consumption and a weak trend towards increa

sed consumption of fruits

may suggest an overall improvement in dietary quality.

Despite the literature suggesting that fruits and vegetables (F&V) can have a protective outcome against overweight, obesity and chronic diseases, consumption is still inadequate. In order to address under consumption of F&V among children, schools have become a platform for a variety of food programs. The Fresh Fruit and Vegetable Program (FFVP), a United States Department of Agriculture (USDA) initiative, aims to increase exposure and consumption of F&V in low-income school children by providing F&V snacks. Participation in FFVP has been associated with higher preference and consumption of F&V and research also suggests that the program has the potential to decrease rates of overweight and obesity. The benefits of this program have been found to extend outside of the school setting, with higher requests for F&V at home and at the grocery store. This study aims to explore how children’s participation in the FFVP influences home food environments and shopping practices through qualitative analysis focus group data. Four focus groups were held with parents (n=25) from three FFVP participating schools. The data was analyzed using an inductive thematic analysis approach to find themes within the discussions. The findings were grouped into three categories: General Perceptions of FFVP, Impact of FFVP on the Home Food Environment, and Impact of FFVP on Shopping Practices. For General Perceptions of FFVP, themes were: Children learn about and enjoy F&V, awareness of farm to school programs, and children make healthier choices. Impact of FFVP on the Home Food Environment included the themes: Choosing heathier foods and snacks, parent F&V behaviors, children request F&V at home, and children talk about or bring F&V home. Finally, Impact of FFVP on Shopping Practices included the themes: children’s involvement in shopping, children request to buy F&V, children request non-produce items, and parents decline or limit unhealthy requests. This qualitative study provides valuable insights about how FFVP participation influences child and family behaviors towards F&V at home and in the grocery store. School food programs, such as the FFVP, have a positive influence on F&V related behaviors among children and should be continued and expanded.

It is presently believed that brown adipose tissue (BAT) is an important tissue in the control of obesity because it has the propensity to increase energy expenditure. The purpose of this study was to attempt to quantify the thermogenesis of BAT when four rats were exposed to a progression of low-fat to high-fat diet. Exogenous norepinephrine (NE) injections (dose of 0.25 mg/kg i.p.) were administered in order to elicit a temperature response, where increases in temperature indicate increased activity. Temperatures were measured via temperature sensing transponders that had been inserted at the following three sites: interscapular BAT (iBAT), the abdomen (core), and lower back (reference). Data showed increased BAT activity during acute (2-3 weeks) high fat diet (HFD) in comparison to low fat diet (LFD), but a moderate to marked decrease in BAT activity during chronic HFD (6-8 weeks) when compared to acute HFD. This suggests that while a HFD may initially stimulate BAT in the short-term, a long-term HFD diet may have negative effects on BAT activation.

Adaptive thermogenesis is an innate mechanism that assists the body in controlling its core temperature that can be stimulated in two ways: cold and diet. When adaptive thermogenesis is stimulated through diet, the metabolic rate of the body should increase and the metabolic efficiency of the body should decrease. This activation should, theoretically, help to control weight gain. A protocol was developed to study four male Sprague-Dawley rats throughout a fourteen week period through the measurement of brown adipose tissue blood flow and brown adipose tissue, back, and abdomen temperatures to determine if diet induced thermogenesis existed and could be activated through norepinephrine. The sedative used to obtain blood flow measurements, ketamine, was discovered to induce a thermal response prior to the norepinephrine injection by mimicking the norepinephrine response in the sympathetic nervous system. This discovery altered the original protocol to exclude an injection of norepinephrine, as this injection would have no further thermal effect. It was found that ketamine sedation excited diet induced thermogenesis in periods of youth, low fat diet, and early high fat diet. The thermogenic capacity was found to be at a peak of 2.1 degrees Celsius during this time period. The data also suggested that the activation of diet induced thermogenesis decreased as the period of high fat diet increased, and by week 4 of the high fat diet, almost all evidence of diet induced thermogenesis was suppressed. This indicated that diet induced thermogenesis is time and diet dependent. Further investigation will need to be made to determine if prolonged high fat diet or age suppress diet induced thermogenesis.

These five communities are being supported by the Robert Wood Johnson Foundation’s New Jersey Partnership for Healthy Kids program to plan and implement policy and environmental change strategies to prevent childhood obesity. Effective interventions for addressing childhood obesity require community-specific information on

who is most at risk and on contributing factors that can be addressed through tailored interventions that meet the needs of the community. Based on comprehensive research, a series of reports are being prepared for each community to assist in planning effective interventions.

The main components of the study were:

• A household telephone survey of 1700 families with 3–18 year old children,

• De-identified heights and weights measured at public schools,

• Assessment of the food and physical activity environments using objective data.

This report presents the results from the household survey. Reports based on school body mass index (BMI) data and food and physical activity environment data are available at www.cshp.rutgers.edu/childhoodobesity.htm.
