    Associations between cigarette prices and consumption in Europe 2004 - 2014

    , Tobacco Control, Vol: 30, Pages: 111-113, ISSN: 0964-4563

    IntroductionWhile tobacco price increases are known to reduce smoking prevalence, these relationships may be blunted by the availability of budget cigarettes, promoted by the tobacco industry to maintain profits. There has been limited previous research on the impact of budget cigarettes on cigarette consumption and used data from Europe 2004-2014 to investigate this.MethodsAnnual population-weighted cigarette consumption per adult data come from the International Cigarette Consumption Database. Annual tobacco price data come from Euromonitor International for 23 European countries. We examined median prices as well as price differentials, operationalised as percentages obtained by dividing the difference between median and minimum prices by median price. We used a linear random-effects model to assess associations between these and cigarette consumption within-year and with a one-year time lag.ResultsCigarette consumption per capita has declined over the study period (-29.5 cigarettes per capita per year, 95% Confidence Intervals -46.8 to -12.1). Our analysis suggests that increases in cigarette price differentials, a marker of opportunities for smokers to switch to less expensive cigarettes, are associated with greater consumption in the same year (+6.4 for a 10% increase in differential, -40.0 to 52.6) and are associated with greater consumption the following year (+67.6, 25.8 to 109.5). ConclusionThese analyses suggest that even in Europe where tobacco taxes are relatively high compared with other regions, differential cigarette pricing strategies may undermine tobacco control. Further research is needed on links between tobacco price structures and consumption and policy design to maximise the effectiveness of tobacco tax.

    Prices and illicit trade of cigarettes in the European Union, a cross-sectional analysis

    , Nicotine and Tobacco Research, Vol: 22, Pages: 2271-2275, ISSN: 1462-2203

    IntroductionWithin the context of the World Health Organization Framework Convention on Tobacco Control Protocol to Eliminate Illicit Trade in Tobacco Products and the impending revision of the EU directive on tobacco excise rules we assessed whether cigarettes price is linked to being offered illicit cigarettes.MethodsWe combined data being offered illicit cigarettes from the 2015 Special Eurobarometer Survey on Illicit Tobacco (N=27,672) with area-level data on Gross Domestic Product, unemployment, perceived corruption and sharing a border with a non-European Economic Area (non-EEA) state. We used the 2015 Weighted Average Price of cigarettes (WAP), which reflects the average price of a cigarette pack in each member state. We assessed associations between prices and illicit trade using 3-level ordered regression models.Results19.6% of respondents reported ever being offered illicit cigarettes, 6.4% repeatedly. In fully adjusted models WAP was not associated with being more likely to have been offered illicit market cigarettes more often (adjusted Odds Ratio=1.02, 95% Confidence Interval 0.91; 1.15). Sharing a border with a non-EEA member state was associated with increased likelihood of reporting being offered illicit cigarettes more often (1.73, 1.26;2.39).ConclusionThis study found no significant association between cigarette prices and reporting being offered illicit cigarettes; sharing a border with a non-EEA member state was linked to illicit trade. This study adds to evidence that increasing prices of cigarettes are not associated with illicit trade and that the focus should remain on securing supply chains, including through features such independent traceability systems.ImplicationsAfter adjusting for individual and regional factors, we did not identify an association between prices of cigarettes and likelihood of reporting being offered illicit cigarettes in the EU. Sharing a border with a non-EEA state however, was associated with increased likelihood of

    Primary health care expansion and mortality in Brazil’s urban poor: a cohort analysis of 1.2 million adults

    , PLoS Medicine, Vol: 17, Pages: 1-20, ISSN: 1549-1277

    BackgroundExpanding delivery of primary health care to urban poor populations is a priority in many low-and middle-income countries. This remains a key challenge in Brazil despite expansion of the country’s internationally recognised Family Health Strategy (FHS) over the past two decades. This study evaluates the impact of an ambitious program to rapidly expand FHS coverage in the city of Rio de Janeiro, Brazil since 2008. Methods and FindingsA cohort of 1,241,351 million low-income adults (observed January 2010-December 2016; total person-years 6,498,607) with linked FHS utilisation and mortality records was analysed using flexible parametric survival models. Time-to-death from all-causes and selected causes were estimated for FHS users and non-users. Models employed inverse probability treatment weighting and regression adjustment (IPTW-RA).The cohort was 61% female (751,895) and had a mean age of 36 years (standard deviation 16.4). Only 18,721 individuals (1.5%) had higher education whilst 102,899 (8%) had no formal education. Two-thirds of individuals (827250; 67%) were in receipt of conditional cash transfers (Bolsa Família). A total of 34,091 deaths were analysed of which 8,765 (26%) were due to cardiovascular disease, 5,777 (17%) due to neoplasms, 5,683 (17%) due to external causes, 3,152 (9%) due to respiratory diseases, and 3,115 (9%) due to infectious and parasitic diseases. One third of the cohort (467,155; 37.6%) used FHS services. In IPTW-RA survival analysis, an average FHS user had a 44% lower hazard of all-cause mortality (HR: 0.56, 95%CI: 0.54 to 0.59, p<0.001) and a five-year risk reduction of 8.3 per 1000 (95%CI: 7.8 to 8.9, p<0.001) compared to a non-FHS user. There were greater reductions in the risk of death for FHS users who: were black (HR:0.50 (95%CI: 0.46 to 0.54, p<0.001)) or pardo (HR:0.57 (95%CI: 0.54 to 0.60, p<0.001) compared to white (HR:0.59 (95%CI: 0.56 to 0.63, p<0.001); had lower educational attainment

    Impact of the Programa Mais médicos (more doctors Programme) on primary care doctor supply and amenable mortality: quasi-experimental study of 5565 Brazilian municipalities

    , BMC Health Services Research, Vol: 20, ISSN: 1472-6963

    BackgroundInvesting in human resources for health (HRH) is vital for achieving universal health care and the Sustainable Development Goals. The Programa Mais Médicos (PMM) (More Doctors Programme) provided 17,000 doctors, predominantly from Cuba, to work in Brazilian primary care. This study assesses whether PMM doctor allocation to municipalities was consistent with programme criteria and associated impacts on amenable mortality.MethodsDifference-in-differences regression analysis, exploiting variation in PMM introduction across 5565 municipalities over the period 2008–2017, was employed to examine programme impacts on doctor density and mortality amenable to healthcare. Heterogeneity in effects was explored with respect to doctor allocation criteria and municipal doctor density prior to PMM introduction.ResultsAfter starting in 2013, PMM was associated with an increase in PMM-contracted primary care doctors of 15.1 per 100,000 population. However, largescale substitution of existing primary care doctors resulting in a net increase of only 5.7 per 100,000. Increases in both PMM and total primary care doctors were lower in priority municipalities due to lower allocation of PMM doctors and greater substitution effects. The PMM led to amenable mortality reductions of − 1.06 per 100,000 (95%CI: − 1.78 to − 0.34) annually – with greater benefits in municipalities prioritised for doctor allocation and where doctor density was low before programme implementation.ConclusionsPMM potential health benefits were undermined due to widespread allocation of doctors to non-priority areas and local substitution effects. Policies seeking to strengthen HRH should develop and implement needs-based criteria for resource allocation.

    Estimating indirect mortality impacts of armed conflict in civilian populations: panel regression analyses of 193 countries, 1990-2017

    , BMC Medicine, Vol: 266, Pages: 1-11, ISSN: 1741-7015

    BackgroundArmed conflict can indirectly affect population health through detrimental impacts on political and social institutions and destruction of infrastructure. This study aimed to quantify indirect mortality impacts of armed conflict in civilian populations globally, and explore differential effects by armed conflict characteristics and population groups.Methods We included 193 countries between 1990 and 2017 and constructed fixed effects panel regression models using data from the Uppsala Conflict Data Program and Global Burden of Disease study. Mortality rates were corrected to exclude battle-related deaths. We assessed separately four different armed conflict variables (capturing binary, continuous, categorical and quintile exposures) and ran models by cause-specific mortality stratified by age groups and sex. Post-estimation analyses calculated the number of civilian deaths. ResultsWe identified 1,118 unique armed conflicts. Armed conflict was associated with increases in civilian mortality - driven by conflicts categorised as wars. Wars were associated with an increase in age-standardised all-cause mortality of 81.5 per 100.000 population (β 81.5, 95% CI 14.3-148.8) in adjusted models contributing 29.4 million civilian deaths (95% CI 22.1-36.6) globally over the study period. Mortality rates from communicable, maternal, neonatal, and nutritional diseases (β 51.3, 95% CI 2.6-99.9), non-communicable diseases (β 22.7, 95% CI 0.2-45.2) and injuries (β 7.6, 95% CI 3.4-11.7) associated with war increased, contributing 21.0 million (95% CI 16.3-25.6), 6.0 million (95% CI 4.1-8.0), and 2.4 million deaths (95% CI 1.7-3.1) respectively. War-associated increases in all-cause and cause-specific mortality were found across all age groups and both genders, but children aged 0-5 years had the largest relative increases in mortality. Conclusions Armed conflict, particularly war, is associated with a substantial indirect mortality impact among civilians

    Size matters: an analysis of cigarette pack sizes across 23 European Union countries using Euromonitor data, 2006 to 2017

    , PLoS One, Vol: 15, ISSN: 1932-6203

    IntroductionThe tobacco industry (TI) has used small cigarette pack sizes to encourage brand-switching and consumption, and to mitigate the impacts of tobacco tax increases. Since 2016, the European Union (EU) Tobacco Products Directive (TPD) specifies a minimum pack size of 20 cigarettes. We examined cigarette pack sizes in the EU and whether pack size composition differed between cheap and expensive price segments, as well as the impact of the revised TPD.MethodsWe conducted a longitudinal analysis of pricing data from 23 EU countries between 2006–2017. We examined pack sizes over time to assess the impact of the TPD, differences in pack size composition between cheap and expensive price segments, and compared gaps in median prices between products using actual and ‘expected’ prices (price if all packs contained 20 sticks).ResultsCigarette pack sizes changed over time, across the EU. The distribution of pack sizes varied between price segments, with small pack sizes especially frequent in the cheap segment of the cigarette market, but this varied over time and across countries. Packs of <20 cigarettes almost disappeared from the data samples after implementation of the TPD.ConclusionImplementation of the TPD appears to have virtually eliminated packs with <20 cigarettes, restricting their use by the TI. Our analysis suggests pack sizes have been used differentially across the EU. Country-level analyses on the industry’s use of pack sizes, consumer responses, and evaluations of restricting certain pack sizes are needed to confirm our findings and strengthen policy.

    The impact of the economic crisis on household health expenditure in Greece: an interrupted time series analysis

    , BMJ Open, Vol: 10, Pages: 1-11, ISSN: 2044-6055

    Objectives and setting The 2008 financial crisis had a particularly severe impact onGreece. To contain spending, the government capped public health expenditure andintroduced increased cost-sharing. The Greek case is important for studying theimpact of recessions on health systems. This study analysed changes in householdhealth expenditure in Greece over the economic crisis and explored whether theimpact differed across socioeconomic groups.Participants We used data from the Greek Household Budget Survey for the years2004 and 2008-2017. The dataset comprised 51,654 households, with a total of128,111 members.Design We compared pre- and post-crisis trends in Greek household out-of-pocketpayments for healthcare from 2004-2017 using an interrupted time series analysis.This study explored spending in Euros and as a share of total household purchases.Results Our results indicated that the population level trend in household healthspending was reversed after the crisis began (pre-crisis trend:€0.040 decrease perquarter (95% CI: -0.785 to -0.022), post-crisis trend:€0.315 increase per quarter(95% CI: -0.004 to 0.635)). We also found that spending on inpatient services andpharmaceuticals has been increasing since the start of the crisis, whereas outpatientservices expenditure has been decreasing. Across all households, out-of-pocketpayments incurred a greater financial burden after the crisis relative to pre-existingtrends, but the poorest households incurred a disproportionately higher burden.Conclusions This was the first study to use an interrupted time series analysis toassess the impact of the economic crisis on household health expenditure in Greece.Our findings suggest that there was an erosion of financial protection for Greekhouseholds as a consequence of the economic crisis. This effect was particularlypronounced amongst poorer households, which is indicative of a regressivefinancing system.

    Potential impacts of post-Brexit agricultural policy on fruit and vegetable intake and cardiovascular disease in England: a modelling study

    , BMJ Nutrition, Prevention & Health, Vol: 3, ISSN: 2516-5542

    Background Current proposals for post-Brexit agricultural policy do not explicitly incorporate public health goals. The revised agricultural policy may be an opportunity to improve population health by supporting domestic production and consumption of fruits and vegetables (F&V). This study aims to quantify the potential impacts of a post-Brexit agricultural policy that increases land allocated to F&V on cardiovascular disease (CVD) mortality and inequalities in England, between 2021 to 2030.Methods We used the previously validated IMPACT Food Policy model and probabilistic sensitivity analysis to translate changes in land allocated to F&V into changes in F&V intake and associated CVD deaths, stratified by age, sex and Index of Multiple Deprivation. The model combined data on F&V agriculture, waste, purchases and intake, CVD mortality projections and appropriate relative risks. We modelled two scenarios, assuming that land allocated to F&V would gradually increase to 10% and 20% of land suitable for F&V production.Results We found that increasing land use for F&V production to 10% and 20% of suitable land would increase fruit intake by approximately 3.7% (95% uncertainty interval: 1.6% to 8.6%) and 17.4% (9.1% to 36.9%), and vegetable intake by approximately 7.8% (4.2% to 13.7%) and 37% (24.3% to 55.7%), respectively, in 2030. This would prevent or postpone approximately 3890 (1950 to 7080) and 18 010 (9840 to 28 870) CVD deaths between 2021 and 2030, under the first and second scenario, respectively. Both scenarios would reduce inequalities, with 16% of prevented or postponed deaths occurring among the least deprived compared with 22% among the most deprived.Conclusion Post-Brexit agricultural policy presents an important opportunity to improve dietary intake and associated cardiovascular mortality by supporting domestic production of F&V as part of a comprehensive strategy that intervenes across the supply chain.

    Trends in tobacco, alcohol and branded fast-food imagery in Bollywood films, 1994-2013

    , PLoS One, Vol: 15, ISSN: 1932-6203

    Background and aimsExposure to tobacco, alcohol and fast-food use in films is associated with initiation of these behaviours. India is the world’s largest film producer, but the extent of such imagery in Bollywood (Hindi cinema) films is unclear. We therefore aimed to describe the extent of and trends in tobacco, alcohol and fast-food imagery in Bollywood films, between 1994–2013.MethodsFor the 15 top-grossing films each year between 1994–2013, the number of five-minute intervals containing product images were determined separately for tobacco, alcohol and fast-food. Both the proportion of films containing at least one image occurrence, and occurrences per film, were described overall and by year. Negative binomial regression described associations between film rating and occurrences/film, and estimated time-trends in occurrences/film, adjusted for rating.ResultsWe analysed 93 U-rated (unrestricted), 150 U/A-rated (parental guidance for children aged <12 years) and 55 A-rated (restricted to adult audience) films, containing 9,226 five-minute intervals (mean intervals/film 30.8, SD 4.0). 70% (n = 210), 93% (n = 278) and 21% (n = 62) of films contained at least one tobacco, alcohol and fast-food occurrence, respectively. Corresponding total mean occurrences/film were 4.0 (SD 4.9), 7.0 (4.7) and 0.4 (0.9). Tobacco occurrences were more common in U/A films (incidence rate ratio 1.49, 95% confidence interval 1.06–2.09) and A films (2.95; 1.95–4.48) than U-rated films. Alcohol occurrences were also more common in A-rated films than U-rated films (1.48; 1.15–1.85). Tobacco occurrences/film became less common over the observed period (adjusted trend -4% per annum; -2 to -7%; p <0.001), while alcohol (+2%; 0–3%; p = 0.02), and fast food (+8%; 2–14%; p = 0.01) occurrences/film became more common.ConclusionsAlthough the extent of tobacco imagery in Bollywood films fell over 1994–2013, it is still frequently observed.

The aim of this study is to systematically review the literature on the impact of armed conflict on cancer in low- and middle-income countries (LMICs).Methods: In November 2019, we searched five medical databases (Embase, Medline, Global Health, PsychINFO and the Web of Science) without date, language or study design restrictions. We included studies assessing the association between armed conflict and any cancer among civilian populations in LMICs. We systematically re-analysed the data from original studies and assessed quality using the Newcastle-Ottawa Scale. Data were analysed descriptively by cancer site.Results: Of 1,543 citations screened, we included 20 studies assessing 8 armed conflicts and 13 site-specific cancers (total study population: 70,172). Two-thirds of the studies were of low methodological quality (score <5) and their findings were often conflicting. However, among outcomes assessed by three or more studies, we found some evi
