To devise a measure of diet quality from short-form FFQ (SFFFQ) for population surveys. validate the SFFFQ against an extensive and 24 h recall.Population-based cross-sectional survey.East Leeds Bolton in Northern England.Adults (n 1999) were randomly selected lists those registered with general practitioner study areas, contacted by mail asked to complete SFFFQ. Responders sent longer if they would take part telephone-based recall.Results 826 people completing SFFFQ, 705 forty-seven recall...
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...
Physical inactivity contributes substantively to disease burden, especially in highly car dependent countries such as New Zealand (NZ). We aimed quantify the future health gain, health-sector cost-savings, and change greenhouse gas emissions that could be achieved by switching short vehicle trips walking cycling Zealand.We used unit-level survey data estimate changes physical activity, distance travelled mode, air pollution for: (a) under 1km (b) 5km a mix of cycling. modelled uptake levels...
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...
<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...
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...
SummaryBackgroundWhat we eat is fundamental to human and planetary health, with the current global dietary transition towards increased red meat intakes ultra-processed foods likely detrimental.MethodsWe modelled five processed replacement scenarios consider equity, greenhouse gas emissions (GHGe), cost outcomes using an established multistate life table model data from New Zealand as a case study of developed, westernised country. Current were replaced with: minimally or plant based...
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...
