The objective of this research is to validate measures of children's diet & physical activity (PA) behaviors & beliefs about diet & PA; study correlates of infant's diet & PA, including biological variables, beliefs/practices, environments, culture, & public policies; study correlates of children's body fatness & metabolic syndrome risk factors; develop & test interventions to change children's diet, PA, body composition & metabolic disease risk factors; study statistical methods for analyzing & clustering a large number of time series, & characterize the optimal policy; and determine the associations between the perceived barriers/facilitators and actual Dietary Guidelines for Americans adherence by different groupings using group appropriate survey instruments. 1)Biological Influences on Children's Diet & PA-understand the influences on those behaviors..
2)Develop & Testing of Interventions to Promote Healthy Dietary Behavior among Youth for Chronic Disease Prevention-Develop & test family & school-based interventions to promote healthy dietary behaviors among families & youth for obesity & chronic disease prevention..
3)Family Influences on the Development of Food Intake Regulation-Investigate whether the tenor of infant feeding affects infant's ability to regulate energy & growth during the first year of life..
4)Relationships between Infant Feeding Patterns and the Development of Risk Factors for Obesity, CV Disease & Diabetes in Early Childhood-Understand the impact of early infant feeding patterns on development of risk factors for obesity, heart disease and metabolic syndrome will provide critical information for development of effective intervention early strategies for reducing the incidence of these chronic debilitating conditions..
5)Investigation of Dietary Intakes of Children-Identify eating pattern "typologies" associated with diet quality & obesity in children & young adults from a biracial population, using cross-sectional & longitudinal approaches..
6)Dietary & Genetic Interactions of Isothiocyanates-In spite of the high chemopreventive potential of isothiocyantes, present in high concentrations of brassica vegetables, critical gaps in our knowledge exist on their intake & function in children & ethnic groups. .

8)Prevention & Treatment of Obesity in Children - Utilize motivational interventions to prevent & treat childhood obesity..
9)Predicting & Explaining Youth PA Behavior - test a promising theoretical model of youth physical activity and to validate scales measuring its constructs.
1b.Approach (from AD-416)
Survey instruments will be constructed/validated to determine different groups of populations’ association between the perceived barriers and facilitators and actual DGA adherence. .
1)Biological Influences on Children's Diet & PA - Integrate how biological & psychosocial variables influence diet & PA using the sensitivity to bitter taste (PROP), as a biological influence on dietary intake; and adiposity, as a biological influence on PA..
2)The Development & Testing of Interventions to Promote Healthy Dietary Behavior among Youth for Chronic Disease Prevention - Evaluate related dietary interventions with children..
3)Family Influences on the Development of Food Intake Regulation - Will be determined through observational measures of mother-infant feeding interactions as well as a weighed food intake protocol to measure infants' energy regulation..
4)Relationships between Infant Feeding Patterns & the Development of Risk Factors for Obesity, CV Disease & Diabetes in Early Childhood - Through a prospective examination of relationships between feeding patterns in the first year of life & risk factors for obesity, heart disease & metabolic syndrome later in childhood. An instrument for characterizing early infant feeding behavior in different ethnic groups will be developed & validated. Infant body composition will be measured within 2 weeks of birth, every 6 months through the 2nd year of life, and yearly thereafter. Maternal and parental body composition will be measured. Weighed diet records will be obtained using data collected by parents and day care providers, and parental control of feeding behavior will be assessed at birth, 1 year, and 3 years of age..
5)Investigation of Dietary Intakes of Children - Conduct sophisticated analyses of the eating patterns & diet quality of 1243 children and 1840 young adults as they relate to obesity, using the Bogalusa Heart Study database compiled from 1973-96 surveys..
6)Dietary and Genetic Interactions of Isothiocyanates - Undertake an approach to advance present methods for measuring dietary intake of isothiocyanates & metabolic activity they induce. This will provide specific targets for preventative and therapeutic interventions that will be particularly important to older children..
7)A Longitudinal Study of Athletic Self-Concept & Physical Activity Behavior in Children & Adolescents - Obtain student measures on a Athletic identity questionnaire, utilizing activity monitors, evaluating parental measures and gaining an insight into the teacher measures for the child..
8)Prevention & Treatment of Obesity in Children - Develop a data collection protocol for future studies, and review datasets to understand correlations between socioeconomic status, dietary intake, & media as they relate to obesity..
9)Predicting & Explaining Youth PA Behavior - Literature review will permit an understanding of variable definition and will permit scale construction. Cognitive interviews will initiate the pilot testing of the scales followed by an analysis utilizing 500 participants.
We have analyzed the large data set in regard to several relationships, including the relationship of PROP sensitivity to adiposity (BMI), the relationship of PROP sensitivity to dietary intake, & the relationship of diet & physical activity (PA) to adiposity (BMI). These analyses motivated us to conduct a literature review of the relationship of PROP sensitivity to dietary intake & food preferences. (Proj.
1)The data analyses for the family intervention was completed, manuscripts prepared, & the materials posted on the CNRC website for free download. The food records from the breakfast study were entered into NDS to obtain nutrient intake & the analyses are continuing. (Proj.
2)During the past year, researchers investigated approaches for accessing and analyzing NHANES 2002-2004 data sets for vegetable intake & brassica vegetable intake, & investigated whether the new National Cancer Institute computer programs that account for sporadic dietary intakes of foods & nutrients could be applied to this analysis. (Proj.
5)Data analysis of several subsets of the data were completed & resulted in 2 published abstracts, 2 presentations at a national meeting and 3 manuscripts. (Proj.
6)Nutritional & PA risk factors for obesity & related disorders were examined in several projects. The project examining risk factors for the metabolic syndrome among US versus Korean young adults was published in a peer-reviewed biomedical journal. A project examining the association between dietary energy density & nutrient density was published in a peer-reviewed biomedical journal. A project examining the nutrient quality of fast food kids meals available in the Houston-metro area was published in a peer-reviewed biomedical journal. The pilot project on a walking school bus evaluation was published in a peer-reviewed biomedical journal. The project on children's active commuting to school was started, examining physical activity as a mediator of the relationship between active commuting to school & adiposity among a nationally representative sample of 12-19 year old adolescents. (Proj.
7)Statistical analyses were conducted to examine item functioning within scales, & correlations among scales in the model were also analyzed. Modifications were made as indicated to enhance scale quality. Additionally, to facilitate recruitment & data collection, the questionnaire was programmed as an online survey, procedures were developed, the online survey was beta tested, and the online study launched. (Project.
8)Analysis occurred using data from extant datasets & appropriate manuscripts were written. (Project.
4)Research studies & literature reviews were conducted to provide a better understanding of parental influences on children's dietary consumption, as well as health & nutrition provider's perceptions of parenting practices intended to promote fruit & vegetable consumption among young children. Both of these efforts will help inform the development of a childhood obesity prevention program for pediatric primary care clinics targeting both the children & the parents to promote healthy lifestyles for the child. (Proj 9)
Use of Media to Educate Others of Obesity Prevention: The prevalence of obesity among children and adolescents has increased 40% since 1960. Children's Nutrition Research Center researchers, in cooperation with the USDA, CSREES, created six videos (in English and Spanish) for each of the six Expanded Food and Nutrition (EFNEP) sessions, based on the formative assessment data collected in the first year of the study. The videos portrayed a fictitious EFNEP class discussing issues on providing healthful home food environments and food parenting tips around the six lessons:.
Influences on Child Obesity: Since obesity is the largest nutrition problem facing children in the US, it is important to understand the influences on child obesity. Studies have disagreed on whether propylthiouracil (PROP) sensitivity (genetically influenced sensitivity to the bitter taste in brassica vegetables) was related to obesity, and the direction of the relationship. It is possible that adolescents learn to like bitter substances (e.g., coffee, alcoholic beverages), and the relationship changes as children entering adolescence relearn their preferences. To address this issue, over a 3-year period Children's Nutrition Research Center researchers collected data on approximately 1,600 students, and through our studies we determined that PROP sensitivity was related to obesity among elementary and high school students only in the top percentage of socioeconomic status (SES). This clarifies the findings in existing studies in which mostly upper SES individuals participated. These findings should redirect this research to identify why the relationship is suppressed in lower SES groups. However, since the relationships was weak (accounting for just 1% of the variance in adiposity), the importance of understanding the influence of PROP sensitivity on adiposity has been minimized. (Project 1: Pediatric Obesity and Chronic Disease Prevention: Influence and Interventions)
1)Nutrition Basics: labeling, MyPyramid,.
2)Breakfast and snacks,.
3)Fruit and vegetables,.
4)Dairy and Meat,.
6)Smart shopping. Resources that were provided to the participants included class outlines, lesson handouts, and goal-setting materials. This intervention was tested in Texas with 100 classes and did result in a reduction in maternal BMI at the end of the program. This study successfully shows how educational multi-media can be used with different ethnic populations for the goal of leading a healthy lifestyle for the prevention of obesity. These materials are available for free download from the Children's Nutrition Research Center website. (Project 2: The development and testing of interventions to promote healthy dietary behavior)
Free Fruit/Vegetable Program Reviewed for Student Intake of New Foods: Poor dietary choices like low fruit and vegetable intakes are associated with overweight, and because this is known the USDA implemented a Free Fruit and Vegetable Program in 2006-2007. One Houston-area high school was selected to participate and received funding to provide baskets of fresh fruit and vegetables daily for each classroom. The Children's Nutrition Research Center scientists conducted a study to assess if this program improved student fruit and vegetable intake. An anonymous, post-intervention only fruit and vegetable intake surveys were distributed to students in the intervention school and a comparison (control) school. Intervention school students were more likely to report eating fruit and 100% fruit juice at least two times per day and total fruit, juice, and vegetables five or more times per day in the last seven days than comparison (control) school students. More intervention school students as compared to comparison (control) school students reported eating fruit at least one time per day. There were no differences in vegetable intake. From this study we can show that free fruit and vegetable distribution programs provide the opportunity for students to taste a variety of fruit and vegetables, and that these programs may improve consumption of certain foods in this adolescent age group. (Project 2: The development and testing of interventions to promote healthy dietary behavior)
Free Fruit/Vegetable Program Reviewed for Student Exposure to New Foods: The USDA sponsors a Free Fruit and Vegetable Program in schools whereby students receive free fruit and vegetable (FV) snacks daily. Children's Nutrition Research Center researchers conducted a study to assess whether the program improved student exposure to and preferences for FV in a Houston high school in 2006-2007. Anonymous, post-intervention surveys addressing only FV exposure and preference were completed by 2,000 intervention school students and by 1,600 students in a comparison (control) school. Differences in FV exposure and preferences were assessed, as well as differences in preferences between those students who tasted the item for the first time at school compared to those who had tasted the item before. The comparison school average scores for prior FV exposure and vegetable preferences were significantly higher than the intervention school scores. Intervention school students who had tasted the item previously reported significantly higher preferences than students who had tasted it for the first time at school. This study indicates that access to the Free Fruit and Vegetable Program did not appear to improve high school student reported FV exposure and preferences. (Project 2: The development and testing of interventions to promote healthy dietary behavior)
Relationships Between Active Commuting to School and Adiposity: Walking or bicycling to school, i.e., active commuting, has the potential for improving physical activity and preventing obesity in youth. Children's Nutrition Research Center scientists examined whether active commuting was inversely associated with adiposity and positively associated with moderate-to vigorous physical activity, and whether physical activity mediated the relationships between active commuting and adiposity. Our study used data on a nationally representative sample of adolescents, and we found that active commuting was inversely associated with BMI, and positively associated with physical activity. Greater before- and after-school physical activity explained part of the relationship between active commuting and waist circumference. We were able to conclude from that study that active commuting to school is a viable population-level intervention to promote physical activity and reduce childhood obesity, and that longitudinal and experimental studies are necessary to confirm these relationships. (Project 7: Prevention and treatment of obesity in children)
Parental Influences on preschool children's fruit and vegetable consumption: Diets that are high in fruit and vegetables have been shown to lower the risk of several chronic diseases and may help prevent overweight; however, most children do not eat the recommended amounts of fruit and vegetables. There is a need to better understand which strategies parents use to promote fruit and vegetable consumption in children and how they are associated with children's actual fruit and vegetable intake. Using data collected from 755 Head Start preschool children and their parents, Children's Nutrition Research Center researchers were able to successfully group parents into three groups based on similar use of fruit and vegetable parenting practices (strategies intended to get their 3- to 5-year-old child to eat fruit and vegetables). Children whose parents were Non-Directive in promoting fruit and vegetables (used enhanced availability/accessibility and teachable moments practices, but less firm discipline practices than the other two groups) consumed more fruit and vegetables than children from the other two groups. Identifying how parents use fruit and vegetable parenting practices in combination helps provide a better understanding of parental influences on children's fruit and vegetable intake and which parenting practices should be promoted in Healthy Lifestyle programs.(Project 9: Helping HAND (Healthy Activity and Nutrition Directions): An obesity prevention program for pediatric primary care.)
Developing Effective Interventions to Help Youth Become More Physically Active: Youth are less physically active than recommended, with continued decreases throughout childhood and adolescence. Theory helps predict, explain, and understand behavior, and provides a blueprint for intervention research; however, there is not a good theoretical model of youth physical activity. Children's Nutrition Research Center scientists are conducting a research study to develop and validate such a model. This fiscal year, our research team successfully conducted statistical analyses to examine item functioning within the scales and correlations among the scales. Future research will validate the scales and the model. The impact of this research is that it will ultimately provide a tested theoretical model of youth physical activity behavior that can be used to guide future intervention research. (Project 8: Predicting and explaining youth physical activity behavior: Model testing and scale validation)
Vegetable Consumption Patterns of Children: Due to genetic variation, there is a subgroup of individuals who are most susceptible to cancer, and who potentially could benefit from isothiocyante intake, found in particular vegetables. Children's Nutrition Research Center nutritionists conducted an analysis of a previous research study for dietary intake, with particular emphasis on food sources of the chemopreventive substance, isothiocynates. Using an existing dataset of dietary assessment on nearly 700 individuals, we were able to show that low-income children do not consume sufficient amounts of vegetables containing isothiocynates, although African-American and Hispanic children tended to consume more than Caucasian children. These studies indicate a greater need to emphasize and promote brassica vegetable intake in children, especially those families that are considered low income. (Project 5: Dietary and genetic interactions of isothiocyanates)
Comparing the Prevalence of Metabolic Syndrome in the United States (US) and Korea: The Metabolic Syndrome is a major health concern that describes the various risk factors assocaiated with diabetes and cardiovascular disease. Children's Nutrition Research Center researchers conducted a study that compared the Metabolic Syndrome among young adults from the US versus Korea using nationally representative databases. Our results showed that young adults from the US had higher rates of the Metabolic Syndrome and three of its components: abdominal obesity, hyperglycemia, and hypertriglyeridemia. Korean young adults had higher rates of low high density lipoprotein-cholesterol or HDL. These findings are of national importance and provide a foundation for the need to customize national policy to prevent the Metabolic Syndrome in the US for obesity and related chronic disease prevention. (Project 7: Prevention and treatment of obesity in children)
Dietary Patterns Associated with Metabolic Syndrome, Socio-Demographic, and Lifestyle Factors in Young Adults: The Bogalusa Heart Study: A need exists to identify differences in dietary patterns (DPs) by socioeconomic, demographic, and lifestyle factors and to examine the relationship between DPs and risk for metabolic syndrome (MetS). Children's Nutrition Research Center researchers reviewed data collected from the Bogalusa (LA) Heart Study (1995-1996) on young adults from a semi-rural community. Dietary intake was assessed from a food frequency questionnaire; sociodemographic information, anthropometrics, and risk factors/score for MetS were evaluated; and factor analysis was used to identify the DPs. Our research team found that the African Americans and males consumed more servings from the (WDP) 'Western Dietary Pattern' (refined grains, high-fat dairy foods, red/processed meats, eggs, cheese dishes, French fries, snacks, sweets/desserts, and sweetened beverages) than their counterparts; white females consumed the fewest servings from the WDP; and that individuals with a higher income and education consumed more servings from the 'Prudent Dietary Pattern' (PDP) which consisted of whole grains, fruits, vegetables, 100% fruit juices, low-fat dairy products, and low-fat salad dressings. From this data, our research team was able to conclude that DPs are associated with sociodemographic and lifestyle factors and the presence of MetS, and that dietary changes may be beneficial in reducing the risk for MetS/and related disorders in this population. (Project 4: Investigation of dietary intakes of children)
Eating Ready-To-Eat Cereal is Positively Associated with Daily Nutrient Intake: Ready-to-eat cereal (RTEC) has been associated with improved nutrient intake and weight status, but intake has not been studied in Hispanic-American (HA) children. Children's Nutrition Research Center researchers assessed whether nutrient intake, the Mean Adequacy Ratio (MAR), and weight were associated with three breakfast consumption groups: breakfast skippers, (RTEC) breakfast consumers, and other breakfast (OB) consumers. Our team conducted a secondary analysis of nutrient intake and weight of over 1,000 Hispanic American children ages 6-12 years and adolescents (13-18 years) included in the 1999-2002 National Health and Nutrition Examination Survey and discovered that 9% of children and 28% of adolescents skipped breakfast; 34% and 22% of those age groups consumed RTEC breakfasts, respectively. Children who consumed an RTEC breakfast had higher intakes of thiamin, riboflavin, niacin, vitamin B-6, folate, calcium, iron, and zinc than children in the OB consumption group and breakfast skippers; RTEC breakfast consumers also had a higher MAR, and higher intakes of phosphorus, magnesium, and potassium than breakfast skippers, but not than OB consumers; RTEC breakfast consumers had lower intakes of total fat, polyunsaturated fatty acid, and cholesterol than other breakfast consumers. We were able to conclude that for Hispanic American children and adolescents, RTEC breakfast consumers had improved nutrient intake compared to breakfast skippers and OB consumers, and RTEC should be encouraged as a convenient, low fat nutrient dense breakfast option. (Project 4: Investigation of dietary intakes of children)
Ready-To-Eat Cereal Breakfasts Permits Improved Nutrient Intake in Black Adolescents: The goal of this study was to determine whether nutrient intake, dietary adequacy, and weight status were associated with type of breakfast consumption: skipping breakfast, consuming ready-to-eat cereal (RTEC) at breakfast, or consuming other types of foods at breakfast. Data from black adolescents 13-18 years of age participating in the 1999-2002 National Health and Nutrition Examination Survey were used in a secondary data analysis conducted by Children's Nutrition Research Center nutritionists. Our analysis showed that 37% of black adolescents skipped breakfast, 19% consumed RTEC at breakfast, and 44% consumed other breakfasts; RTEC breakfast and other breakfast consumers had higher mean energy intakes than breakfast skippers, and after adjusting for gender and energy intake, RTEC breakfast consumers had higher intakes of vitamins A, B-6, B-12; thiamin; riboflavin, niacin; folate; calcium, phosphorus, magnesium, iron, zinc, and potassium than breakfast skippers and other breakfast consumers. We conclude that, if confirmed in prospective studies, consuming a breakfast meal with RTEC may be a useful strategy to encourage in black adolescents as a way to improve nutrient intake and dietary adequacy without increasing weight. (Project 4: Investigation of dietary intakes of children)
Whole Grain Consumption by Children Improves Diet Quality/Nutrient Intake: Children's Nutrition Research Center researchers examined the association that whole grain consumption has on diet quality and nutrient intake in a recent, nationally representative sample of children/adolescents from the 1999-2004 National Health and Nutrition Examination Survey. Nutritionists conducted a secondary analysis of data collected on children/adolescents (2-5 years, 6-12 years, and 13-18 years). We found that the mean number of servings of whole grains consumed was 0.45, 0.59, and 0.63 for children/adolescents 2-5 y, 6-12 y, and 13-18 y, respectively. In children 2-5 years, Healthy Eating Index, and intake of energy, fiber, vitamins A, C, B1, B6, folate, magnesium, phosphorus, and iron increased with increasing consumption of whole grains; intake of protein, added sugars, total fat, saturated fatty acids, monounsaturated fatty acids, and cholesterol decreased. We were able to conclude that the overall consumption of whole grains in this population was low; however, diet quality and nutrient intake in children/adolescents was significantly improved with increasing consumption of whole grains. (Project 4: Investigation of dietary intakes of children)
Are African-American Children's Breakfast Consumption Patterns Associated With Weight Status: The objective of this study was to assess whether weight status, nutrient intake, and dietary adequacy were associated with breakfast consumption patterns. A representative sample of the US population was used in a Children's Nutrition Research Center secondary analysis of nutrient intake/diet quality and weight status by breakfast consumption patterns using the 1999-2002 National Health and Nutrition Examination Survey (NHANES). The study sample included African-American children 1-12 years of age. We found that 45% of children 1-5 years of age and 38% of those 6-12 years of age consumed ready-to-eat cereal (RTEC) at breakfast, while 7.4% and 16.9% in those age groups skipped breakfast, respectively. RTEC breakfast consumers had the highest mean intakes of vitamins A, B-6, and B-12; thiamin; riboflavin; niacin; folate; calcium; iron; and zinc, and the highest Mean Adequacy Ratio. We were able to conclude that consuming a RTEC breakfast was associated with improved weight and nutrient adequacy in African-American children; African-American children in all breakfast categories still had mean intakes of most nutrients below recommended levels. The implications are that consuming a breakfast meal should be encouraged in these children, and that RTEC at breakfast provides important nutrients and may help promote a healthy weight. (Project 4: Investigation of dietary intakes of children)
Whole Grain Consumption and Body Weight Measures in 6- to 18-Year Olds: Children's Nutrition Research Center researchers examined the relationship of whole grain consumption with anthropometric and adiposity measures in children and adolescents by conducting a secondary analysis from the National Health and Nutrition Examination Survey (NHANES) 1999-2004. We found that the mean whole grain intake was 0.59 and 0.63 servings/day among 6- to 12-year olds and 13- to 18-year olds, respectively. In children 6-12 years old, whole grain intake was not associated with BMI or waist circumference. In adolescents 13-18 years olds BMI but not waist circumference was significantly lower in the highest whole grain consumption group. We were able to conclude that the overall consumption of whole grain was below current recommendations of 3 servings per day. (Project 4: Investigation of dietary intakes of children)
