Policy-makers need to know how much of ethnic inequalities in health are due to socioeconomic position and tobacco smoking, but quantifying this is surprisingly difficult. In this Blog, and accompanying video, we summarize new research using NZ’s linked census-mortality data, blended with innovative new ‘counterfactual’ methods to determine causal relationships that can shed light on policy-relevant questions. A half or more of Māori:European/Other inequalities in mortality are due to four socioeconomic factors (education, labour force status, income and deprivation), and this percentage is stable over time for males but increasing for females. Eradicating tobacco will not only improve mortality for all sociodemographic groups, but reduce absolute inequalities in mortality between Māori and European/Other by a quarter. It is hard to think of another intervention that will reduce inequalities by as much.

In this blog we consider recent literature (particularly reviews) on the effectiveness and cost-effectiveness of dietary counselling as a health intervention. Most studies suggest that dietary counselling is effective though the benefits are typically modest and short-term. The literature on cost-effectiveness is mixed, and there is substantial uncertainty about long-run cost-effectiveness given the typically short-term trials involved. Addressing the obesogenic environment will have potentially (much) larger gains, and due to substantial reductions in obesity-related disease it is likely to be cost-saving. However, governments, policy-makers and the public are often interested in counselling interventions, necessitating close attention to cost-effectiveness of these interventions relative to more structural changes to the environment.

In this fourth blog that features the BODE3 Interactive League Table, we look at substantive findings across the interventions (so far) in the league table. We use graphs from the league table to cautiously explore (for fear of over-generalizing) what approaches might typically generate the most health gain and be best value-for-money.

Last week we introduced the concept of league tables to compare interventions. This week we provide a brief ‘user guide’ for our just launched BODE3 Interactive League Table. We walk through how to pull down tables and graphs of health gain (quality-adjusted life-years; QALYs), health system costs and cost effectiveness for 50+ interventions currently in the interactive league table.

This blog introduces league tables, and more specifically the NZ-specific BODE3 Interactive League Table, for comparing interventions on health gain, cost and cost-effectiveness – and potentially many other things. A league table is a useful tool for researchers and policy-makers to get an informed ‘first impression’ of what are the best health interventions to give further consideration to investing in, or disinvesting in.
