Thesis (M.A.)--Boston University / Background: In the past decade, a growing body of research has shown a link between attention-deficit/hyperactivity disorder (ADHD) and obesity. Recently, studies in adults and children began exploring the possible neurobiological and behavioral mechanisms responsible for the association of ADHD with obesity. Stimulant medications used to treat ADHD might also play a protective role against weight gain in individuals with ADHD. Objective: The current pilot study set out to create and test a protocol that explores differences in obesogenic eating behaviors between typically developing (TD) children and children with ADHD who are either taking ADHD medication (ADHD-M) or have been off of ADHD medication (ADHD-NM) for the past 3 months. Given that children with ADHD are often on medication, this pilot also allowed us the opportunity to assess the feasibility of recruiting children with ADHD-NM. Methods: The Children's Eating Behaviour Questionnaire (CEBQ) was used to measure eating behaviors between three groups of 6-11 year old children; TD (n=6), ADHD-M (n=9), and ADHD-NM (n=3). To our knowledge this is the first study to use the CEBQ as a measure of eating behaviors in children with ADHD. The protocol consisted of a telephone screen for inclusion and exclusion criteria, followed by one study visit where the CEBQ was administered along with 4 other questionnaires that will be analyzed as part of a larger study. Information was also collected on recruitment efforts, effectiveness of screening tools, and duration of study visit. Results: We found statistically significant differences in satiety responsiveness (p=0.008) among children with ADHD-M and ADHD-NM, and difference (p=0.022) among children with ADHD-M and typically developing (TD) in the desire to drink domain. We observed in the fussiness domain, borderline significant differences among children with ADHD-M and TD children (p=0.079) and in the emotional under-eating domain differences for children with ADHD-M and children with ADHD-NM (p=0.066). Also, there was a trend in the food responsiveness domain that suggested children with ADHD-NM were more responsive to food cues than the other two groups. There were no statistically significant differences seen between ADHD-NM and TD groups in the following three domains; slowness in eating, enjoyment of food, and emotional over-eating. As suspected, it was difficult to recruit children with ADHD-NM therefore; the small sample size may have limited our ability to detect significant differences. Conclusion: The pilot study showed statistically significant differences in one obesogenic CEBQ domain, satiety responsiveness, and a possible trend in the food responsiveness, which is another obesogenic domain. The differences suggest that children with ADHD-NM might be less responsive to internal satiety cues than children with ADHD-M, and more responsive to food cues than TD children or children with ADHD-M. The pilot also suggested differences between groups in three other domains; desire to drink, fussiness, and emotional undereating. Exploring these possible differences further could give insight into the mechanism contributing to the observed higher obesity risk in individuals with ADHD compared to individuals without ADHD.

<p>Preschoolers in the US are not meeting dietary guidelines, which is concerning since experience with foods during early childhood may influence food preferences in later life. To better understand why preschoolers are not meeting dietary guidelines it is necessary to understand the factors that influence why parents offer their children specific foods. The purpose of this study was to use the means-end framework and the laddering interview technique to better understand <i>why </i>parents of preschoolers decide to offer their children certain foods and <i>why</i> certain feeding strategies are helpful. A total of 33 parents of preschoolers (3–5-year-olds) completed one-on-one phone interviews regarding the foods they typically offer their child. Laddering data were elicited for three food groupings: foods parents typically offer, foods parents typically avoid, and foods parents prefer to offer. The resulting data were analyzed and summarized in a series of hierarchical value maps (HVMs). Parent and child-centric themes emerged as factors that influenced the foods parents offered their preschooler. The results of this study provide insight into the meanings and beliefs that impact the food decisions and feeding strategies used by parents of preschoolers.</p>

This thesis deals with an influence of nutrition on growth and development of children. Theoretical part is dealing in details about nutrition facts from an early childhood to adolescence. Practical part of the thesis deals with questionare-research, performed at Prague elementary schools and high school. Number of probands was 192. The total number of girls was 107, 88 girls from elementary schools and 19 from high school. The total number of boys was 85, 58 boys from elementary schools and 27 from high school. Age spectrum was between 10 and 18 years. Questionaire was focused on basic eating habits, which play an important role in presence of overweight and obesity in childhood. At the same time, we evaluated anthropometric parameters - body weight, height and BMI. Keywords: pediatric nutrition, principles of healthy nutrition, alternative nutrition, eating disorders
