Objective Global health challenges include non-communicable disease burdens, ensuring food security in the context of rising prices, and environmental constraints around production, e.g., greenhouse gas [GHG] emissions. We therefore aimed to consider optimized solutions mix items daily diets for a developed country population: New Zealand (NZ). Methods conducted scenario development linear programming model 16 (some with uncertainty). Data inputs included nutrients foods, wastage...
Objective There is growing international interest in advancing ‘the tobacco endgame’. We use New Zealand (Smokefree goal for 2025) as a case study to model the impacts on smoking prevalence (SP), health gains (quality-adjusted life-years (QALYs)) and cost savings of (1) 10% annual tax increases, (2) tobacco-free generation (TFG), (3) substantial outlet reduction strategy, (4) sinking lid supply (5) combination 1, 2 3. Methods Two models were used: dynamic population forecasting SP closed...
BackgroundOne possible policy response to the burden of diet-related disease is food taxes and subsidies, but net health gains these approaches are uncertain because substitution effects between foods. We estimated cost impacts various subsidies in one high-income country, New Zealand.MethodsIn this modelling study, we compared Zealand a 20% fruit vegetable subsidy, saturated fat, sugar salt (each set at level that increased total price by same magnitude decrease from subsidy), an 8%...
Background Countries are increasingly considering how to reduce or even end tobacco consumption, and raising taxes is a potential strategy achieve these goals. We estimated the impacts on health, health inequalities, system costs of ongoing tax increases (10% annually from 2011 2031, compared no ["business as usual," BAU]), in country (New Zealand) with large ethnic inequalities smoking-related noncommunicable disease (NCD) burden. Methods Findings modeled 16 tobacco-related diseases...
Background Given the high importance of dietary sodium (salt) as a global disease risk factor, our objective was to compare impact eight reduction interventions, including feasible and more theoretical ones, assist prioritisation. Methods Epidemiological modelling cost-utility analysis were performed using Markov macro-simulation model. The setting New Zealand (NZ) (2.3 million citizens, aged 35+ years) which has detailed individual-level administrative cost data. Results Of most largest...
Most evidence on health-related food taxes and subsidies relies observational data effects single nutrients or foods instead of total diet. The aim this study was to measure the effect randomly assigned price variations consumer purchasing, where sets prices emulated commonly discussed tax subsidy policies, including a fruit vegetables, sweetened beverage tax, according sugar, sodium, saturated fat content.In study, adult participants (≥18 years) in New Zealand completed up five weekly shops...
BackgroundMyocardial infarction mortality has declined since the 1970s, but contemporary drivers of this trend remain unexplained. The aim study was to compare contribution trends in event rates and case fatality declines myocardial four high-income jurisdictions from 2002–15.MethodsLinked hospitalisation data were obtained New South Wales (NSW), Australia; Ontario, Canada; Zealand; England, UK. People aged between 30 years 105 included study. Age-adjusted estimated Poisson binomial...
<h3>Background</h3> Since there is some evidence that the density and distribution of tobacco retail outlets may influence smoking behaviours, we aimed to estimate impacts 4 outlet reduction interventions in a country with smoke-free goal: New Zealand (NZ). <h3>Methods</h3> A multistate life-table model 16 tobacco-related diseases, using national data by sex, age ethnicity, was used quality-adjusted life years (QALYs) gained net costs over remainder 2011 NZ population9s lifetime. The assumed...
A "diet high in sodium" is the second most important dietary risk factor for health loss identified Global Burden of Disease Study 2013. We therefore aimed to model gains and costs (savings) salt reduction interventions related substitution maximum levels bread, including by ethnicity age. also ranked these four compared eight other modelled interventions.A Markov macro-simulation was used estimate QALYs gained net system sodium interventions, discounted at 3 % per annum. The setting New...
Pricing policies such as taxes and subsidies are important tools in preventing controlling a range of threats to public health. This is particularly so tobacco alcohol control efforts change dietary patterns physical activity levels means addressing increases noncommunicable diseases. To understand the potential impact pricing policies, it critical nature price elasticities for consumer products. For example, key parameters models any food tax or subsidy that aims quantify health impacts...
Obesity is an important risk factor for many chronic diseases. Mobile health interventions such as smartphone apps can potentially provide a convenient low-cost addition to other obesity reduction strategies.This study aimed estimate the impacts on quality-adjusted life-years (QALYs) gained and system costs over remainder of life span New Zealand population (N=4.4 million) app promotion intervention in 1 calendar year (2011) using currently available weight loss.The was national mass media...
Dietary salt reduction is included in the top five priority actions for non-communicable disease control internationally. We therefore aimed to identify health gain and cost impacts of achieving a national target sodium reduction, along with component targets different food groups.We used an established dietary intervention model study 10 interventions achieve targets. The 2011 New Zealand (NZ) adult population (2.3 million aged 35+ years) was simulated over remainder their lifetime Markov 3...
Abstract Aim We aimed to combine Global Burden of Disease (GBD) Study data and local identify the highest priority intervention domains for preventing cardiovascular disease (CVD) in case study country Aotearoa New Zealand (NZ). Methods Risk factor CVD NZ were extracted from GBD using “GBD Results Tool.” prioritized risk based on consideration size health burden (disability-adjusted life years [DALYs]) then by domain-specific interventions that delivered gains cost-savings. Based DALYs, five...
<h3>Objective</h3> We examine the potential role for taxation in tobacco endgame New Zealand, where goal is to become 'smokefree' (less than 5% smoking prevalence) by 2025. <h3>Design</h3> Modelling study using a dynamic population model. <h3>Setting and participants</h3> Māori non-Māori men women. <h3>Interventions</h3> Annual increases excise tax of 5%, 10%, 15% 20% (with 10% reflecting annual increase recently legislated Zealand Government 2016). <h3>Results</h3> With continued commitment...
To optimise planning of public health services, the impact high-cost users needs to be considered. However, most existing statistical models for costs do not include many clinical and social variables from administrative data that are associated with elevated care resource use, increasingly available. This study aimed use machine learning approaches big predict among people cardiovascular disease (CVD).We used nationally representative linked datasets in New Zealand CVD prevalent cases...
Abstract Artificial intelligence (AI) and machine learning (ML) pose enormous potential for improving quality of life. It can also generate significant social, cultural other unintended risks. We aimed to explore fairness concepts that be applied in ML models disease prediction from key health experts’ perspectives an ethnically diverse high-income country. In-depth interviews with experts the sector Aotearoa New Zealand (NZ) were implemented between July December 2022. invited participants...
While severe outcomes among hospitalised patients with COVID-19 and influenza are well described, comparative studies on community transmission milder illnesses associated lacking. We compared incidence, risk/protective factors, clinical features prospective cohort participants PCR-confirmed COVID-19-associated influenza-associated acute respiratory (ARI) from 7-February to 2-October 2022 in Wellington, New Zealand. The crude ARI incidence was 59/100 person-years (PY). adjusted cumulative...
To develop a new method for estimating the cost to governments of enacting public health legislation.We adopted central government perspective in costs. The parliamentary legislative acts and regulations New Zealand was calculated from proportion time devoted law-making (i.e. sitting days debating chamber), associated policy advice agencies documented issues related law-making. relative costs were estimated number pages that, between 1999 2010, 26.7% resources 16.7% generating laws Zealand....
