The principal aim of this study was to assess risk factors for LBW in a large multi-ethnic and socio-economically disadvantaged population. Data from 3242 mothers, who attended the Well Baby Clinic (Southwestern Sydney, Austra...

There is increasing interest in the role played by maternal depression in mediating the effects of adversity during pregnancy and poor infant outcomes. There is also increasing evidence from multilevel regression studies for an association of area-level economic deprivation and poor individual mental health. The purpose of the study reported here i...
Background/Objectives: Vietnam has limited information on the nutritional status of children aged ≥5 years. This study aimed to 1) determine the nutritional status, and 2) assess the associations between malnutrition and socio-demographic factors among children and adolescents aged 5-19 years in selected provinces in Vietnam.

OBJECTIVES
Depression in medical students is concerning, potentially fueled by many stressors including career choice-relating stress. Choosing Medicine is a life-long commitment, and low intrinsic motivation or excessive dependence on family can complicate this decision and adding stress throughout their training. This stress intensifies in the fi...
Slow‐onset disasters, a neglected climatic event, affect the agricultural sector in Southeast Asia and threaten regional food security.

Introduction:
Endovascular treatment for acute ischemic stroke patients with large vessel occlusion (LVO) has been established as a promising clinical intervention within a late time window of 6-24 h after symptom onset. Patients with slow progression, however, may still benefit from endovascular treatment beyond the 24-h time window (very late wi...
During the first year of the COVID-19 pandemic, the state of Queensland, Australia, had relative success in containing viral transmission, presenting a unique case for potential insights into effective crisis management. Limited research exists into the communication style and effectiveness of Chief Health Officers (CHOs) throughout pandemic scenar...
Global climate change has contributed to the intensity, frequency, and duration of heatwave events. The association between heatwaves and elderly mortality is highly researched in developed countries. In contrast, heatwave impact on hospital admissions has been insufficiently studied worldwide due to data availability and sensitivity. In our opinio...
Queensland experienced relatively low case numbers during the first year of the coronavirus disease 2019 (COVID‐19) pandemic. This may be due to timely, stringent policies, yet there is currently no research evaluating this link, despite the state government playing such a primary role in the pandemic response. This ecological study used a cross‐se...
Issues addressed:
The overabundance of conflicting nutrition information (CNI) and accompanying confusion and backlash are a public health concern; however, the complexity of responses to CNI has yet to be explored. The following mixed methods study brings depth to the perceptions and behavioural responses to CNI among the Australian millennials t...
Poor household dietary diversity has been linked to malnutrition in individuals, households, and cumulatively in populations. High rates of malnutrition among Khmer ethnic children aged five years and younger have been reported in Tri Ton district, Vietnam. This paper aims to further investigate household dietary diversity and associated factors am...

Background
Waist circumference (WC) is an indicator of intra-abdominal adipose tissue, high levels of which confer an increased risk of cardiometabolic disease. Population data on WC should be more informative than data on body mass index (BMI), which is a general indicator of body size. This study aimed to evaluate the importance of WC relative to...
