This assessment task asks you to critically evaluate population based dietary data, interpret intakes by comparing against national nutrient recommendations, identify and critique any associated health risks and propose relevant, evidence based solutions to improve health. By completing this task you will have the opportunity to develop and receive feedback on the following unit learning outcomes:

1. ….
2. Select and use appropriate technologies to locate, critique and interpret individual and population based dietary data, national nutrient and food based dietary recommendations and peer reviewed nutrition literature.
3. Apply effective written and oral communication skills to disseminate evidence based nutrition knowledge to specialist and non-specialist

Task:

The table below describes Calcium intake data collected as part of the 2011-2012 Australian National Nutrition and Physical Activity Survey (NNPAS).  http://www.abs.gov.au/AUSSTATS/[email protected]/DetailsPage/4364.0.55.0072011-12?OpenDocument (accessed June 2017)

Table: Mean intake of calcium by age group and gender (mg/day)

Your assignment is to write an 1800 word article discussing the calcium results, and provide a one minute audio recording suitable for a radio audience summarising the health implications of current intake levels. Address each of the points outlined below in your assignment. Your written article can be presented in any format (that is, there is no prescription of font size or line spacing) but should have a logical flow and include supporting evidence from at least five original peer reviewed scientific articles to support your argument. Review papers may be included but they are in addition to the 5 original research articles. There is no age limit on the articles that you select to include in your assignment. Do not cite references from internet sources, and non-peer reviewed literature unless there is a strong reason to do so. Do not use the HSN702 study guide as reference, but reference can be made to journal articles included in the reader and as such must be cited from the original article. Use the mark allocation to guide how much detail is expected for each question based on the total word limit of the assignment. The reference section and any in-text citation do not add to the word count, all other text are to be included in the word count. You must provide the word count at the start of your written assignment.

Address the following points:

Part A: Written Assignment (1800 words)

1. Locate and critique population based dietary data: Describe and critically evaluate the method used to collect the calcium intake data in the Is dietary data considered an accurate reflection of calcium intake?
2. Interpret population based dietary data: Compare the intake data with the Nutrient Reference Values (NRV) for calcium, specifically the Estimated Average Requirement (EAR) and Recommended Dietary Intake (RDI). What proportion of the population did not meet the EAR for calcium? Justify why you use the EAR for this comparison as opposed to the
3. Identify nutrition issues, locate & critique peer reviewed nutrition literature: Identify and critically evaluate the evidence from peer reviewed journals linking

   calcium  intakeswith adverse health outcomes in children and adolescents.

4. Evidence based solution to current intake levels: What changes, if any, would you recommend to improve current intake levels of calcium in this population?

Part B: Oral presentation (1 minute)

1. Convince an informed, intelligent but not necessarily scientific, radio audio of your point of view regarding calcium intake levels, health implications and any change necessary.

The one minute audio file needs to be uploaded in either MP3, MP4, WMA or WAV format. All smart phones come with several different voice memo programs which you can use but you may need to convert these files to one of these preferred formats. There are a range of freeware programs that enable you to convert files. If you experience any difficulties please contact Deakin e-solutions. In addition you can use AudioNote for Mac computers, and for PC you can use the program: Windows Sound Recorder, (needs a working microphone); go to Program Menu > Accessories > Windows Sound Recorder. Press the record button, and begin talking.
