BACKGROUND Good quality antenatal care (ANC) reduces maternal and neonatal mortality and improves health outcomes, particularly in low-income countries. Quality of ANC is measured by three dimensions: number of visits, timing of initiation of care and inclusion of all recommended components of care. Although some studies report on predictors of the first(More)
BACKGROUND Since the introduction of childhood vaccination for diphtheria in 1932 and the widespread use of vaccines to prevent tetanus, pertussis (whooping cough) and poliomyelitis in the 1950s, deaths in Australia from vaccine preventable diseases (VPDs) have declined by more than 99%. It is important, however, that the downward trend in morbidity and(More)
BACKGROUND Anecdotal reports suggest that the addition of fentanyl (an opioid) to epidural analgesia for women during childbirth results in difficulty establishing breastfeeding. The aim of this paper is to determine any association between epidural analgesia and 1) breastfeeding in the first week postpartum and 2) breastfeeding cessation during the first(More)
Pertussis notifications have increased over the past decade in Australia and other industrialised countries. This study estimates the effectiveness of pertussis vaccination in one Australian State (New South Wales, NSW) among children aged less than 14 years, during a period when an Australian whole-cell pertussis vaccine was in routine use. Cases notified(More)
BACKGROUND Australia introduced a fifth dose of pertussis vaccine at 4 to 5 years of age in 1994, the first country to do so for some 40 years. We report trends in national pertussis notifications from 1993 to 2001. METHODS Notified pertussis cases were analyzed by age and year of disease onset. RESULTS Before the fifth dose was introduced, notification(More)
BACKGROUND In 2010, intense focus was brought to bear on febrile convulsions in Australian children particularly in relation to influenza vaccination. Febrile convulsions are relatively common in infants and can lead to hospital admission and severe outcomes. We aimed to examine the relationships between the population incidence of febrile convulsions and(More)
Methicillin-resistant Staphylococcus aureus (MRSA) has been notifiable in Western Australia since 1985. This article reviews the notification data from 1994 to 1997, focusing on increases in MRSA notifications and the proportion that are local strains; changes in the geographical distribution of MRSA; and changes in antibiotic-resistance patterns.
Specific interventions included in the review To be included, the trials had to use delayed pushing. The duration of delay varied between the studies. In some studies it was between one and three hours (or earlier if there was an involuntary desire to push), in others women were delayed until the head became visible at introitus or rotation and descent(More)
BACKGROUND There is a need to develop sustainable and clinically effective weight management interventions that are suitable for delivery in community settings where the vast majority of overweight and obese adolescents should be treated. This study aims to evaluate the effect of additional therapeutic contact as an adjunct to the Loozit group program -- a(More)
BACKGROUND The Loozit(®) Study is a randomised controlled trial investigating extended support in a 24 month community-based weight management program for overweight to moderately obese, but otherwise healthy, 13 to 16 year olds. METHODS This pre-post study examines the two month outcomes of the initial Loozit(®) group intervention received by both study(More)
