This publication is the second release of information from the National Health Measures Survey (NHMS), the biomedical component of the 2011–13 Australian Health Survey (AHS). Around 11,000 respondents aged 5 years and over across Australia voluntarily provided blood and/or urine samples, which were tested for a range of chronic disease and nutrient biomarkers. This publication focuses on the test results for nutrients, including folate, iodine, Vitamin B12, iron and Vitamin D. More detailed data for each of these nutrients is available in the tables in the Data downloads section below.
