Introduction: Hyperlipidemia is a major risk factor for cardiovascular disease. Tests of blood lipid concentrations require a blood sample to be taken in a clinical setting, which is costly, time-consuming, and may preclude measurements in a large number of people at risk. Hypothesis/Objective: This study aimed to develop artificial neural network...

Globally, the migration of unaccompanied minors is increasing, however, the experiences of these children have not been examined. We systematically synthesised the existing qualitative literature to examine the experiences of children undergoing forced separation from their parents during migration. The review was structured based on the PRISMA sta...

Introduction and hypothesis: Pelvic floor disorders (PFDs), including urinary incontinence (UI), faecal incontinence (FI) and pelvic organ prolapse (POP), are common debilitating conditions globally, with considerable variation of prevalence reported in low and middle-income countries (LMICs). It was hypothesised that the variation could be due to...

Introduction: Women experience poorer clinical outcomes after Acute Coronary Syndrome (ACS). While the reason for this differential is unclear, autonomic function -indicative of vagal and sympathetic modulation directed to the sinus node- is a candidate mechanism. Hypothesis: That sex-specific differences in heart rate variability (HRV) in the year...

Objective Phobic anxiety is a risk factor for poor prognosis following Acute Coronary Syndrome (ACS). A psychophysiological marker of vagal function, autonomic dysfunction may play a critical role in this relationship. The aim of the study was two-fold: to assess whether phobic anxiety was characterised by autonomic dysfunction (heart rate variabil...

Background: While several efficacy trials have demonstrated diabetes risk reduction through targeting key lifestyle behaviours, there is a significant evidence gap in relation to the successful implementation of such interventions in low- and middle-income countries (LMICs). This paper evaluates the implementation of a cluster randomised controlle...

Methods: This research consisted of a quantitative study using ACFDR data and...

Background Cervical cancer (CCa) and breast cancer (BCa) are the two leading cancers in women worldwide. Early detection and education to promote early diagnosis and screening of CCa and BCa greatly increases the chances for successful treatment and survival. Screening uptake for CCa and BCa in low and middle - income countries (LMICs) is low, and...

Introduction Pelvic floor disorders (PFDs) including urinary incontinence, faecal incontinence and pelvic organ prolapse are common debilitating conditions among women in high-income countries. However, PFDs in women in low/middle-income countries (LMICs) have not been studied extensively. We aim to conduct a systematic review and meta-analysis of...

We conducted a qualitative study that explored the views and perceptions of migrant women in, Dandenong, Victoria, Australia about sociocultural barriers and health needs during pregnancy and in the postnatal period. The study was informed by the Social Identity Theory and the Acculturation Theory. It involved five focus group discussions with 35 m...

Background Despite a plethora of studies examining the effect of increased urbanisation on health, no single study has systematically examined the measurement properties of scales used to measure urbanicity. It is critical to distinguish findings from studies that use surrogate measures of urbanicity (e.g. population density) from those that use me...

To explore medical decision making in octogenarians having cardiac surgery. Five focus groups conducted in a private hospital setting with octogenarians of high socioeconomic status who had successful cardiac surgery in the previous 3-13 months. Octogenarians motivations for having cardiac surgery include survival, relief of symptoms, convenience a...

Objectives: This article examines the link between stressful life events and illness by considering both onset and reoccurrence of chronic illnesses. Using longitudinal data, we estimate the extent to which life events increase the likelihood of depression or anxiety, type 2 diabetes, cancer, coronary heart disease, circulatory disease, asthma and...

We measured osteoporosis knowledge in an older adult population with minimal trauma fracture. At follow-up, health literacy and osteoporosis knowledge had not changed significantly from baseline, and 14 (23 %) patients reported not taking any osteoporosis medication. Current osteoporosis care does not result in increased patient knowledge about the...

Medical student numbers in Australian universities have more than doubled since 2000. There are concerns about the ability for existing clinical training sites to accommodate this increase in student numbers, and there have been calls to increase training in private hospitals. The receptiveness of patients in private hospitals will influence the su...

Adiponectin, high-density lipoprotein cholesterol (HDL-C) and insulin concentrations may be important in the pathophysiology of cardiovascular disease. We tested the hypothesis that serum adiponectin rather than insulin differs from early life, between South Asians and Europeans, with a potentially key role in excess cardiovascular risk characteris...

Unlabelled: Studies testing whether birth weight and childhood obesity differ by gender are lacking. We aimed to describe the relationship between birth weight and childhood overweight/obesity and investigate the influence that gender has on this relationship among 4 to 5-year-old children. We performed a secondary analysis of an Australian nation...

Aortic pulse wave velocity (aPWV), a noninvasive measure of vascular stiffness, is an independent predictor of cardiovascular disease both before and in overt vascular disease. Its characteristics in early life and its relationship to maternal factors have hardly been studied. To test the hypothesis that infant aPWV was positively related to matern...

This study explored the health, well-being, and social capital benefits gained by community members who are involved in the management of land for conservation in six rural communities across Victoria.

Adiponectin is a recognized protective risk marker for cardiovascular disease in adults and is associated with an optimal lipid profile. The role of adiponectin at birth is not well understood, and its relationship with the neonatal lipid profile is unknown. Because ethnic disparities in cardiovascular risk have been attributed to low adiponectin a...
