BACKGROUND: This study examined whether adaptation of existing antitobacco television and radio advertisements (ads) from high-income countries is a viable tobacco control strategy for Africa. METHODS: 1078 male and female adult smokers and non-smokers, aged 18-40 years, from major and smaller urban locations in Kenya, Nigeria and Senegal, were recruited into groups using locally appropr...

BACKGROUND: Disseminated Gonococcal Infection (DGI) is caused by Neisseria gonorrhoeae bacteraemia. Typically the primary source is a sexually acquired mucosal infection. If not recognised and treated promptly DGI can be associated with significant morbidity and, in rare cases, death. Central Australia has one of the highest rates of gonococcal notifications in Australia. Despite this, the n...

OBJECTIVES: To undertake the first comprehensive analysis of the incidence of three curable sexually transmissible infections (STIs) within remote Australian Aboriginal populations and provide a basis for developing new control initiatives. METHODS: We obtained all results for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) testing conducted during 2...

OBJECTIVES: To determine the co-occurrence and epidemiological relationships of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) in a high-prevalence setting in Australia. METHODS: In the context of a cluster randomised trial in 68 remote Aboriginal communities, we obtained laboratory reports on simultaneous testing for CT, NG and TV by nucleic acid a...

OBJECTIVES: To examine whether the introduction of intermittent standing bouts during the workday using a height-adjustable workstation can improve subjective levels of fatigue, musculoskeletal discomfort and work productivity relative to seated work. METHODS: Overweight/obese office workers (n=23; age 48.2±7.9 years, body mass index 29.6±4 kg/m(2)) undertook two, 5-day experimental conditio...

BACKGROUND: Disruption of 11p15 imprinting results in two fetal growth disorders with opposite phenotypes: the Beckwith-Wiedemann (BWS; MIM 130650) and the Silver-Russell (SRS; MIM 180860) syndromes. DNA methylation defects account for 60% of BWS and SRS cases and, in most cases, occur without any identified mutation in a cis-acting regulatory sequence or a trans-acting factor. METHODS: We i...

BACKGROUND: We aimed to investigate the relationship between potentially modifiable risk factors in middle age and disability after 13 years using the Framingham Offspring Study (FOS). We further aimed to develop a disability risk algorithm to estimate the risk of future disability for those aged 45-65 years. METHODS: FOS is a longitudinal study. We used examination 5 (1991-1995; 'baseline')...

BACKGROUND: A single assessment of psychological distress, which includes depression and anxiety, has been associated with increased mortality in patients with coronary heart disease, but the prognostic importance of persistence of distress symptoms is less certain. AIM: To determine whether intermittent and/or persistent psychological distress is associated with long-term cardiovascular...

OBJECTIVE: Supplemental oxygen therapy may increase myocardial injury following ST-elevation myocardial infarction (STEMI). In this study, we aimed to evaluate the effect of the dose and duration of oxygen exposure on myocardial injury after STEMI. METHODS: Descriptive analysis of data from a multicentre, prospective, randomised, controlled trial of 441 patients with STEMI randomised to ...

OBJECTIVE: New imaging techniques have permitted the detection of subclinical LV dysfunction (LVD) in up to half of patients with type 2 diabetes mellitus (DM) with a normal EF. However, the connection between early LVD and prognosis is unclear. This study aimed to define the long-term outcome of LVD associated with type 2 DM. METHODS: In this prospective cohort study, 230 asymptomatic p...

OBJECTIVE: In the majority of studies, the effect of physical activity (PA) on cardiovascular disease (CVD) and mortality is estimated at a single time point. The impact of long-term PA is likely to differ. Our study objective was to estimate the effect of long-term adult-life PA compared with long-term inactivity on the risk of incident CVD, all-cause mortality and CVD-attributable mortality. ...

OBJECTIVE: We examined cognitive function in older hospitalised patients with chronic atrial fibrillation (AF). DESIGN: A prospective substudy of a multicentre randomised trial of an AF-specific disease management intervention (the Standard versus Atrial Fibrillation spEcific managemenT studY; SAFETY). SETTING: Three tertiary referral hospitals within Australia. PATIENTS: A total of 260 pati...

BACKGROUND: Limited strategies have been developed to evaluate and address the alarming discrepancy in early mortality between Indigenous and non-Indigenous populations. OBJECTIVE: To assess heart failure (HF), HF risk factors and document cardiac characteristics in an Australian Aboriginal population. DESIGN, SETTING, PARTICIPANTS: Adults were enrolled across six Aboriginal communities in...

Objective To further the understanding of the factors influencing outcome following rheumatic heart disease (RHD) related mitral valve surgery, which globally remains an important cause of heart disease and a particular problem in Indigenous Australians. Methods The Australian Cardiac Surgery Database was utilised to assess outcomes following mitral valve repair and replacement for RHD and n...

BACKGROUND: Emergency medical services (EMS) transport to hospital is recommended in acute coronary syndrome (ACS) guidelines, but only half of patients with ACS currently use EMS. The recent Australian Warning Signs campaign conducted by the Heart Foundation addressed some of the known barriers against using EMS. Our aim was to examine the influence of awareness of the campaign on these bar...

PURPOSE: To estimate the Australian cancer burden attributable to lifestyle-related risk factors and their combinations using a novel population attributable fraction (PAF) method that accounts for competing risk of death, risk factor interdependence and statistical uncertainty. PARTICIPANTS: 365 173 adults from seven Australian cohort studies. We linked pooled harmonised individual part...

OBJECTIVE: To identify the factors associated with 'good' mental health among Aboriginal children living in urban communities in New South Wales, Australia. DESIGN: Cross-sectional survey (phase I of a longitudinal study). SETTING: 4 Aboriginal Community Controlled Health Services that deliver primary care. All services were located in urban communities in New South Wales, Australia....

OBJECTIVES: To compare the acute effects of uninterrupted sitting with sitting interrupted by brief bouts of light-intensity walking on self-reported fatigue, cognition, neuroendocrine biomarkers and cardiometabolic risk markers in overweight/obese adults. DESIGN: Randomised two-condition crossover trial. SETTING: Laboratory study conducted in Melbourne, Australia. PARTICIPANTS: ...

INTRODUCTION: Australian Aboriginal children are more likely than non-Aboriginal children to have developmental vulnerability at school entry that tracks through to poorer literacy and numeracy outcomes and multiple social and health disadvantages in later life. Empirical evidence identifying the key drivers of positive early childhood development in Aboriginal children, and supportive feature...

OBJECTIVES: Suicide rates have widely been reported to peak in spring and summer. A frequent hypothesis is that increased sunlight exposure alters biological mechanisms. However, few attempts have been made to systematically untangle the putative suicidogenic risk of sunlight exposure from that of seasonality. We examined whether average hours of daily sunlight in a month confer additional ris...
