Remoteness, race and social disadvantage: disparities in hepatocellular carcinoma incidence and survival in Queensland, Australia.

BACKGROUND & AIMS: Incidence and mortality of hepatocellular carcinoma (HCC) is increasing globally, but varies between countries and regions. To target scarce resources to most need, clinical services must be informed by regional epidemiology. Using population-based data, we sought to document the incidence and mortality of HCC in Queensland, Australia, a state occupying a vast land area with diverse at-risk subpopulations. METHODS: Using population-based data from 1996 to 2011, the age-standardised incidence rate (ASR), annual percentage change (APC) and survival of HCC in Queensland were assessed with negative binomial regression, Kaplan-Meier and Cox survival analysis. Spatial patterns of HCC incidence and survival and relevant predictors were mapped. RESULTS: Thousand six hundred and twenty HCCs were diagnosed during this study period, with an overall ASR of 2.00-cases/1000 population. ASR increased by 3.5% per year, (95% CI: 2.1 to 5.0), P < 0.001) among males to 5.6/100,000 in 2011 and a non-significant increase of 2.6% per year, (95% CI = -0.7 to 6.0), P = 0.111) among females to 1.6/100,000 in 2011. Higher incidence was associated with male gender, older age, major city residence and proportionally higher area Indigenous population. Thousand and two hundred and eighty-seven patients died. Median survival was approximately 10 months. Five-year survival improved from 18% in 1996-2000 to 24% in 2006-2011 (P < 0.001). Poorer survival was associated with older age, less recent period of diagnosis, lower hepatitis B prevalence in country of origin and greater area-level social disadvantage. CONCLUSIONS: Over this study period, HCC incidence increased significantly. HCC survival improved but remains poor. Social determinants are critical to HCC epidemiology.

Unintended Consequences of COVID-19 Non-Pharmaceutical Interventions (NPIs) for Population Health and Health Inequalities.

Since the start of the COVID-19 pandemic in early 2020, governments around the world have adopted an array of measures intended to control the transmission of the SARS-CoV-2 virus, using both pharmaceutical and non-pharmaceutical interventions (NPIs). NPIs are public health interventions that do not rely on vaccines or medicines and include policies such as lockdowns, stay-at-home orders, school closures, and travel restrictions. Although the intention was to slow viral transmission, emerging research indicates that these NPIs have also had unintended consequences for other aspects of public health. Hence, we conducted a narrative review of studies investigating these unintended consequences of NPIs, with a particular emphasis on mental health and on lifestyle risk factors for non-communicable diseases (NCD): physical activity (PA), overweight and obesity, alcohol consumption, and tobacco smoking. We reviewed the scientific literature using combinations of search terms such as 'COVID-19', 'pandemic', 'lockdowns', 'mental health', 'physical activity', and 'obesity'. NPIs were found to have considerable adverse consequences for mental health, physical activity, and overweight and obesity. The impacts on alcohol and tobacco consumption varied greatly within and between studies. The variability in consequences for different groups implies increased health inequalities by age, sex/gender, socioeconomic status, pre-existing lifestyle, and place of residence. In conclusion, a proper assessment of the use of NPIs in attempts to control the spread of the pandemic should be weighed against the potential adverse impacts on other aspects of public health. Our findings should also be of relevance for future pandemic preparedness and pandemic response teams.
