RESUMO
BACKGROUND: Obstructive sleep apnoea (OSA) is common in children and adolescents with Down syndrome (DS). Clinical guidelines recommend that all children with DS have polysomnography (PSG) for assessment of OSA by the age of 4 years, but access is limited and testing may be burdensome for children and families. METHODS: The purpose of this prospective cross-sectional cohort study was to identify a model to predict OSA in this group that could be tested in an external population to triage children and adolescents with DS for PSG. These models were based on a comprehensive set of potential predictive demographic, anthropometric, quality of life and sleep-related variables. RESULTS: The results of this study show the predictive power of a model based on the sleep disordered breathing subscale of the Pediatric Sleep Survey Instrument and sleep fragmentation quantified using actigraphy in determining moderate-severe OSA in children and adolescents with DS. This model exhibits high sensitivity (82%), specificity (80%), positive predictive value (75%) and negative predictive value (86%). CONCLUSIONS: We demonstrate the utility of a tool containing the sleep disordered breathing subscale of the Pediatric Sleep Survey Instrument and sleep fragmentation quantified using actigraphy in identifying children and adolescents with DS who have moderate/severe OSA.

Home economics and health teachers are to be found in many parts of the world. They teach students about food in relation to its nutritional, safety and environmental properties. The effects of such teaching might be expected to be reflected in the food knowledge of adults who have undertaken school education in these areas. This study examined the food knowledge associations of school home economics and health education among Australian adults. Two separate online surveys were conducted nationwide among 2022 (November 2011) and 2146 Australian adults (November-December 2012). True/false and multiple choice questions in both surveys were used to assess nutrition, food safety and environmental knowledge. Knowledge scores were constructed and compared against respondents' experience of school health or home economics education via multiple regression analyses. The results from both studies showed that home economics (and similar) education was associated with higher levels of food knowledge among several age groups. The associations of home economics education with food knowledge differed across several Australian states and recall of home economics themes differed across the age groups. These findings suggest that home economics education may bring about long-lasting learning of food knowledge. Further research is required, however, to confirm the findings and to test the causal influence of home economics education on adults' food knowledge.
