Abstract : Comparison of Two School Feeding Programmes in Ghana, West Africa
|
|
Abstract: Background:Malnutrition of children in Ghana continues during school years. There is limited information on how school meals meet nutrient recommendations in Ghana. Objectives:The aim of this study was to compare energy and nutrient content of meals served by Ghana School Feeding Programme (GSFP) and Non-Governmental School Feeding Programme (NGSFP) and adherence to nutrient recommendations. Methods:This was a cross sectional study design involving observation of school meals at two sites: GSFP and NGSFP. Average weights of a week’s meal were converted to energy and nutrient equivalence and compared with international recommendations. Differences assessed with t-tests. Results:NGSFP provided significantly higher portion size (416 ± 96 g vs. 243 ± 50 g; p=0.007), energy (776 ± 427 kcal vs. 315 ± 24 kcal; p=0.042) and fats (17± 8 vs. 6 ± 2; p=0.019) but similar micronutrient contributions to GSFP. NGSFP met energy and macronutrient recommendation set by World Food Programme; whereas, GSFP did not meet the recommendations. Conclusion and Recommendations:The NGSFP had more energy and macronutrients per serving size than the GSFP. Regulation of meals served by GSFP should be reviewed to ensure they contribute to the adequacy of children’s diets as well as meet recommendations set by World Food Programme.

Abstract : Effect of Music Interventions on Sedation in Children Undergoing Magnetic Resonance Imaging: Clinical Trial
|
|
Abstract: Background: Although parenteral sedation is often required in MRI studies in children, it is stressful and increases the cost of healthcare. Objectives: We evaluated the impact of music interventions in children receiving parenteral sedation for MRI studies on total number of doses of sedation medications, sedation time, levels of cortisol and cytokines, sedation success, adverse events, parental satisfaction, and cost savings. Methods: We conducted a prospective open unblinded four-arm clinical evaluation of interventions on 471 children 1-12 years of age undergoing MRI and receiving parenteral sedation. Children were assigned to active music therapy (AMT), facilitated music listening (FML), and as comparison another intervention (child life intervention or CLI), or no intervention (NI); measures included number of doses of sedation medications, time of sedation, sedation success, adverse events, parental satisfaction, and salivary levels of the stress hormone cortisol and pro-inflammatory cytokines, before and after intervention. Results: The total number of sedation doses, total sedation time, and levels of salivary cortisol and cytokines did not differ between the four groups. One FMLA choice, Wee Sing Animal Songs, resulted in significant decrease in total sedation time and reduction of associated costs. Conclusions: The use of one type of FML led to decreased total sedation time in children. This is an important finding since FML is an inexpensive non-invasive intervention which could be of significant time and cost saving benefits.

Abstract : Use of Stand-Biased Desks to Reduce Sedentary Time in High School Students: A Pilot Study
|
|
Abstract: Background: The purpose of this pilot study was to identify differences between sitting and standing time in high school students’ pre and post stand-biased desk intervention. Methods: ActivPal3™ activity monitors were affixed to 25 Bryan Collegiate High School students’ to monitor their standing time and activity levels. Data were collected at the beginning of the school year (fall) in traditional seated desks and in the spring in stand-biased desks. After attrition, 18 of the original 25 students were included in the final analysis. The physical activity data (steps) as well as standing and sitting time data provided by the monitors was used for within subject intervention analyses. Results: Descriptive statistics and a two-sided t-test were used to analyse differences between pre and post intervention sitting and standing times. Analysis indicated a significant reduction of sitting time post stand-biased desk intervention (p<0.0001) and a significant increase in standing time, post stand-biased desk intervention (p<0.0001). Analysis also revealed a non-statistically significant (p < 0.0619) average increase of 2,286 steps per school day when comparing mean steps pre-intervention (6,612) and post-intervention (8,898). Conclusions: Standing desks have the potential to reduce sedentary behavior and increase light to moderate physical activity for high school students during the school day. Keywords: Sedentary behavior, stand-biased desk, high school students. |
Abstract : Is Neck Circumference a Marker for Cardiovascular Risk in Obese Adolescents?
|
|
Abstract: Background: Weight excess has become a public health problem worldwide, reaching about 200 million children, of whom 40 to 50 million are obese. Obesity in childhood is associated with increased blood pressure (BP), high triglycerides, low HDL-cholesterol and abnormal glucose metabolism. Visceral fat is a stronger predictor of metabolic dysfunction and cardiovascular risk than total body adiposity. Assessment of neck circumference (NC) is an easy method, which can serve as screening to identify individuals with weight excess. Our study aim was to examine associations between NC with BP values, lipid profile, blood glucose and fasting insulin in obese adolescents and verify the reproducibility of measurements of NC. Methods: 82 adolescents aged 10 to 17 years were included in the study, being 43 (22 boys and 21 girls) with obesity and 39 with normal weight (20 boys and 19 girls). Results: Significant associations were observed between NC and BMI, BP, HDL cholesterol, insulin and HOMA-IR. Disagreement between both observers for NC was observed in 5.2% of the sample, only concerning obese individuals. Conclusion: Our findings strengthen the knowledge about the potential value of NC as a tool for identifying patients at risk for hypertension, insulin resistance, and obesity. However as with the waist circumference it may be flawed in obese individuals. Keywords: Neck circumference, obesity, adolescent, cardiovascular diseases, diagnosis. |
