Abstract : The Children in Action Pilot Study
|
|
Abstract: Interventions that can successfully alter the trajectory toward obesity among high-risk children are critical if we are to effectively address this public health crisis. The goal of this pilot study was to implement and evaluate an innovative physical activity program with Hispanic-American (HA) preschool children attending Head Start. The Children in Action (CIA) program was a five month physical activity intervention. This intervention was a pilot study with 3- to 5-year-olds enrolled in four HA Head Start centers. After baseline assessment, centers were matched by enrollment and randomly assigned to either the intervention or the control condition. A total of 295 preschool children were randomly selected across the four centers. The primary endpointsof this study were favorable changes in physical activity levels and gross motor skills. Using mixed effect time-series regression models, changes in weight was a secondary endpoint. We did not observe a statistical difference between intervention and control groups in physical activity levels during the awake time, gross motor skills,or weight status. Process evaluation data showed that there was adherence to protocols and the intervention was delivered 92% of the time, four times per week, during the five month intervention. We demonstrated that it is feasible to conduct the SPARK-Early Childhood (EC) curriculum among preschool children attending Head Start centers but that an increased dose and/or longer intervention duration will be required to impact gross motor skills, physical activity levels and weight status during this critical early childhood development stage.

Abstract : Suboptimal Omega-3 Levels in Australian Adolescents
|
|
Abstract: Objective:To quantitate the omega-3 status in a cohort of Australian adolescents. Design, Setting and Participants:A cross-sectional descriptive study of 251 apparently healthy adolescents (192 female, 59 male) aged 15-17 years, in year 11, from 10 schools within the Northern Sydney and Central Coast areas of New South Wales. Participants provided a morning non-fasting blood sample via finger-prick and written answers to specific demographic and lifestyle questions. Omega-3 index was calculated by adding %EPA and %DHA values in the whole blood. Equivalent erythrocyte omega-3 index values were obtained by using conversion factors (1.33 for EPA and 2.22 for DHA) from published erythrocyte/whole blood values. Main Outcome Measures: Quantitation of the individual, and estimation of the group average, blood omega-3 Index. Results:The blood omega-3 Index for this adolescent cohort ranged from 2.1-22.3 with a mean of 8.3±3.2, and median of 7.8. On average males had a higher omega-3 Index compared to females (10.5±3.7 vs 7.7±2.6, p<0.001). Fifty three percent of adolescents tested had an omega-3 Index below the optimum of >8. Three percent had an Index of <4, placing them in the high risk category for disease. On average, adolescents from low or medium socioeconomic communities had a significantly lower omega-3 Index compared to those from higher socioeconomic neighbourhoods (mean difference=1.4, p=0.018). Overall 20% of boys and 17% of girls reported regularly taking omega-3 supplements. Regular use of omega-3 supplements was associated with a higher average omega-3 Index (9.8±3.7, n=44 compared to 8.0±3.0, n=203, p=0.001 in those not taking supplements). Conclusion:This study indicates that Australian adolescents, even when from advantaged homes, have a high probability of below optimum omega-3 levels. As reduced omega-3 levels are linked to conditions of public health concern such as diabetes, asthma and depression, targeted strategies to improve the omega-3 status in the childhood population may be warranted.

Abstract : Impact of Vegetable Preparation Method and Taste-Test on Vegetable Preference for First Grade Children in the United States
|
|
Abstract: How children rate vegetables may be influenced by the preparation method. The primary objective of this study was for first grade students to be involved in a cooking demonstration and to taste and rate vegetables raw and cooked. First grade children of two classes (N= 52: 18 boys and 34 girls (approximately half Hispanic) that had assented and had signed parental consent participated in the study. The degree of liking a particular vegetable was recorded by the students using a hedonic scale of five commonly eaten vegetables tasted first raw (pre-demonstration) and then cooked (post-demonstration). A food habit questionnaire was filled out by parents to evaluate their mealtime practices and beliefs about their child’s eating habits.Paired sample t-tests revealed significant differences in preferences for vegetables in their raw and cooked states. Several mealtime characteristics were significantly associated with children’s vegetable preferences. Parents who reported being satisfied with how often the family eats evening meals together were more likely to report that their child eats adequate vegetables for their health (p=0.026). Parents who stated that they were satisfied with their child’s eating habits were more likely to report that their child was trying new foods (p<.001). Cooking demonstrations by nutrition professionals may be an important strategy that can be used by parents and teachers to promote vegetable intake. It is important that nutrition professionals provide guidance to encourage consumption of vegetables for parents so that they can model the behavior of healthy food consumption to their children.

Abstract : Promotion of Fruits and Vegetables Consumption: Results of a School-Based Intervention in a Sample of 13-15 Years Old Italian Students
|
|
Abstract: Background: The …e vai con la frutta (let’s go with fruit) project was designed to respond to the worrying low consumption of fruits and vegetable in the large portion of population, especially in youth. The main objective was to increase fruit and vegetable consumptions at school level. Methods: In 2010/11, we randomly selected subjects from middle and high schools in five Italian regions. The subjects were randomly divided into two groups: intervention (I) and control (C). A questionnaire on fruits and vegetables consumption was administered, at the baseline as well as at end of the period. The sample size was evaluated on the expected frequency of 0.5 for a binomial random variable, of ± 1.54% with IC of 95%. Results:These results confirmed that adolescent students at baseline survey eat less than the amount of fruits and vegetables consumption recommended by the International guidelines. After the intervention time, we observed an increment in fruits and vegetables consumptions both in middle and high school students. Regarding the impact of the intervention on the factors like knowledge, attitudes and behaviour, there was a positive change in the behaviour only in the intervention group, in coherence with the consumption variations examined. Conclusions: This study is the first time that fruits and vegetables were offered at such a large scale through vending machines at schools in five regions. Several vending companies under this project agreed to revise the list of healthy snacks offered to eliminate those clearly classified as junk foods.
