We describe the design and baseline results of a trial in the Illawarra region of New South Wales, Australia. Methods The HealthTrack study is a 12 month randomised controlled trial testing effects of a novel interdisciplinary lifestyle intervention versus usual care. The study recruited overweight and obese adults 25-54 years resident in the Illawarra. Primary outcomes were weight, and secondary outcomes were disease risk factors (lipids, glucose, blood pressure), and behaviour (diet, activity, and psychological factors). Protocols, recruitment and baseline characteristics are reported. Results Between May 2014 and April 2015, 377 participants were recruited and randomised. The median age (IQR) of the mostly female sample (74%) was 45 (37-51) years. The sample comprised obese kg/m2) well educated (79% post school qualifications) non-smokers (96%). A high proportion reported suffering from anxiety (26.8%) and depression (33.7%). Metabolic syndrome was identified in 34.9% of the sample. Conclusions The HealthTrack study sample was recruited to test the effectiveness of an interdisciplinary approach to preventive healthcare in self-identified overweight adults in the Illawarra region. The profile of participants gives some indication of those likely to use services similar to the trial design.

Associations between Dietary Patterns and Blood Pressure in a Clinical Sample of Overweight Adults

“…The detailed study protocol is described elsewhere [24]. In brief, the study recruited adults 25-54 years of age through advertisements in local newspapers Individuals who could not communicate in English, had severe medical conditions that limited their ability to participate in the study, immunodeficiency, had medical conditions that could limit survival to 1 year, reported excessive alcohol intakes (greater than 50 grams of alcohol per day) or illegal drug use, or had difficulties in participating in some parts of the study were excluded.…”

Development of a matching file of Australian food composition databases (AUSNUT 2007 to 2011–13)

“…To the authors' knowledge, this study is the first to develop an AUSNUT Golley et al, 2015;Louie et al, 2015;Meng et al, 2010;Neale et al, 2013;Tapsell et al, 2014;Waern et al, 2015;Wood et al, 2014), including in recent research such as the HealthTrack study (Tapsell et al, 2015). This was despite the database being developed in line with a survey food.…”

“…AUSNUT 1999 and Government Department of Health and Ageing, 2008). Until the release of AUSNUT 2011-13, AUSNUT 2007 was the most timely food composition survey database available in Australia, and has been widely applied in nutrition research (Elliott et al, 2014;Golley et al, 2015;Louie et al, 2015;Meng et al, 2010;Neale et al, 2013;Tapsell et al, 2014;Tapsell et al, 2015;Waern et al, 2015;Wood et al, 2014).…”

“…In order to demonstrate its use in the clinical trial context, the matching file was applied to baseline dietary data collected during the HealthTrack study, a randomised controlled trial aimed at exploring the effect of an interdisciplinary intervention on weight loss (Tapsell et al, 2015). Dietary data was collected using a paper-based four day food record, and was initially analysed in Foodworks © nutrient analysis software (Version 7, Xyris Software, QLD, Australia, 2012) using the AUSNUT 2007 database, as it was the most recent food composition survey database available at the time of study commencement.…”

Relationship between sodium and potassium intake and blood pressure in a sample of overweight adults

“…Detailed study protocol is reported elsewhere [14]. In brief, the HealthTrack study enrolled adults aged between 25 and 54 years recruited through advertisements in local newspapers from the Illawarra community, a major coastal region 70 km south of Sydney, Australia.…”
