BACKGROUND The global economic crisis has been associated with increased unemployment and reduced public-sector expenditure on health care (PEH). We estimated the effects of changes in unemployment and PEH on cancer mortality, and identified how universal health coverage (UHC) affected these relationships. METHODS For this longitudinal analysis, we obtained data from the World Bank and WHO (1990-2010). We aggregated mortality data for breast cancer in women, prostate cancer in men, and colorectal cancers in men and women, which are associated with survival rates that exceed 50%, into a treatable cancer class. We likewise aggregated data for lung and pancreatic cancers, which have 5 year survival rates of less than 10%, into an untreatable cancer class. We used multivariable regression analysis, controlling for country-specific demographics and infrastructure, with time-lag analyses and robustness checks to investigate the relationship between unemployment, PEH, and cancer mortality, with and without UHC. We used trend analysis to project mortality rates, on the basis of trends before the sharp unemployment rise that occurred in many countries from 2008 to 2010, and compared them with observed rates. RESULTS Data were available for 75 countries, representing 2.106 billion people, for the unemployment analysis and for 79 countries, representing 2.156 billion people, for the PEH analysis. Unemployment rises were significantly associated with an increase in all-cancer mortality and all specific cancers except lung cancer in women. By contrast, untreatable cancer mortality was not significantly linked with changes in unemployment. Lag analyses showed significant associations remained 5 years after unemployment increases for the treatable cancer class. Rerunning analyses, while accounting for UHC status, removed the significant associations. All-cancer, treatable cancer, and specific cancer mortalities significantly decreased as PEH increased. Time-series analysis provided an estimate of more than 40,000 excess deaths due to a subset of treatable cancers from 2008 to 2010, on the basis of 2000-07 trends. Most of these deaths were in non-UHC countries. INTERPRETATION Unemployment increases are associated with rises in cancer mortality; UHC seems to protect against this effect. PEH increases are associated with reduced cancer mortality. Access to health care could underlie these associations. We estimate that the 2008-10 economic crisis was associated with about 260,000 excess cancer-related deaths in the Organisation for Economic Co-operation and Development alone. FUNDING None.

Objective Economic measures such as unemployment and gross domestic product are correlated with changes in health outcomes. We aimed to examine the effects of changes in government healthcare spending, an increasingly important measure given constrained government budgets in several European Union countries. Design Multivariate regression analysis was used to assess the effect of changes in healthcare spending as a proportion of total government expenditure, government healthcare spending as a proportion of gross domestic product and government healthcare spending measured in purchasing power parity per capita, on five mortality indicators. Additional variables were controlled for to ensure robustness of data. One to five year lag analyses were conducted. Setting and Participants European Union countries 1995–2010. Main outcome measures Neonatal mortality, postneonatal mortality, one to five years of age mortality, under five years of age mortality, adult male mortality, adult female mortality. Results A 1% decrease in government healthcare spending was associated with significant increase in all mortality metrics: neonatal mortality (coefficient −0.1217, p = 0.0001), postneonatal mortality (coefficient −0.0499, p = 0.0018), one to five years of age mortality (coefficient −0.0185, p = 0.0002), under five years of age mortality (coefficient −0.1897, p = 0.0003), adult male mortality (coefficient −2.5398, p = 0.0000) and adult female mortality (coefficient −1.4492, p = 0.0000). One per cent decrease in healthcare spending, measured as a proportion of gross domestic product and in purchasing power parity, was both associated with significant increases (p < 0.05) in all metrics. Five years after the 1% decrease in healthcare spending, significant increases (p < 0.05) continued to be observed in all mortality metrics. Conclusions Decreased government healthcare spending is associated with increased population mortality in the short and long term. Policy interventions implemented in response to the financial crisis may be associated with worsening population health.

Rapid adjustment to free-market systems, which often takes place during economic crises, poses serious problems for public health outcomes. At a time of economic crisis, it is particularly important to understand the relationship between economic circumstances and public health outcomes. As more countries are forced to adopt free-market models of economic austerity, a number of threats to public health prospects emerge. Therefore we suggest that we are not only in an economic crisis, but also in a health crisis—a “healthconomic crisis.” Further exploration of these issues is needed if we are to recommend more sustainable global public health solutions during the coming years.

Background The global economic downturn has been associated with unemployment rises, reduced health spending, and worsened population health. This has raised the question of how economic variations affect health outcomes. Aim We sought to determine the effect of changes in unemployment and government healthcare expenditure on cerebrovascular mortality globally. Methods Data were obtained from the World Bank and World Health Organization. Multivariate regression analysis was used to assess the effect of changes in unemployment and government healthcare expenditure on cerebrovascular mortality. Country-specific differences in infrastructure and demographics were controlled for. One- to five-year lag analyses and robustness checks were conducted. Results Across 99 countries worldwide, between 1981 and 2009, every 1% increase in unemployment was associated with a significant increase in cerebrovascular mortality (coefficient 187, CI: 86·6–288, P = 0·0003). Every 1% rise in government healthcare expenditure, across both genders, was associated with significant decreases in cerebrovascular deaths (coefficient 869, CI: 383–1354, P = 0·0005). The association between unemployment and cerebrovascular mortality remained statistically significant for at least five years subsequent to the 1% unemployment rise, while the association between government healthcare expenditure and cerebrovascular mortality remained significant for two years. These relationships were both shown to be independent of changes in gross domestic product per capita, inflation, interest rates, urbanization, nutrition, education, and out-of-pocket spending. Conclusions Rises in unemployment and reductions in government healthcare expenditure are associated with significant increases in cerebrovascular mortality globally. Clinicians may also need to consider unemployment as a possible risk factor for cerebrovascular disease mortality.

BACKGROUND: Government health care spending (GHS) is of increasing importance to child health. Our study determined the relationship between reductions in GHS and child mortality rates in high- and low-income countries. METHODS: The authors used comparative country-level data for 176 countries covering the years 1981 to 2010, obtained from the World Bank and the Institute for Health Metrics and Evaluation. Multivariate regression analysis was used to determine the association between changes in GHS and child mortality, controlling for differences in infrastructure and demographics. RESULTS: Data were available for 176 countries, equating to a population of ∼5.8 billion as of 2010. A 1% decrease in GHS was associated with a significant increase in 4 child mortality measures: neonatal (regression coefficient [R] 0.0899, P = .0001, 95% confidence interval [CI] 0.0440–0.1358), postneonatal (R = 0.1354, P = .0001, 95% CI 0.0678–0.2030), 1- to 5-year (R = 0.3501, P < .0001, 95% CI 0.2318–0.4685), and under 5-year (R = 0.5207, P < .0001, 95% CI 0.3168–0.7247) mortality rates. The effect was evident up to 5 years after the reduction in GHS (P < .0001). Compared with high-income countries, low-income countries experienced greater deteriorations of ∼1.31 times neonatal mortality, 2.81 times postneonatal mortality, 8.08 times 1- to 5-year child mortality, and 2.85 times under 5-year mortality. CONCLUSIONS: Reductions in GHS are associated with significant increases in child mortality, with the largest increases occurring in low-income countries.

BACKGROUND The global economic crisis has been associated with increased unemployment, reduced health-care spending and adverse health outcomes. Insights into the impact of economic variations on cancer mortality, however, remain limited. METHODS We used multivariate regression analysis to assess how changes in unemployment and public-sector expenditure on health care (PSEH) varied with female breast cancer mortality in the 27 European Union member states from 1990 to 2009. We then determined how the association with unemployment was modified by PSEH. Country-specific differences in infrastructure and demographic structure were controlled for, and 1-, 3-, 5- and 10-year lag analyses were conducted. Several robustness checks were also implemented. RESULTS Unemployment was associated with an increase in breast cancer mortality [P < 0.0001, coefficient (R) = 0.1829, 95% confidence interval (CI) 0.0978-0.2680]. Lag analysis showed a continued increase in breast cancer mortality at 1, 3, 5 and 10 years after unemployment rises (P < 0.05). Controlling for PSEH removed this association (P = 0.063, R = 0.080, 95% CI -0.004 to 0.163). PSEH increases were associated with significant decreases in breast cancer mortality (P < 0.0001, R = -1.28, 95% CI -1.67 to -0.877). The association between unemployment and breast cancer mortality remained in all robustness checks. CONCLUSION Rises in unemployment are associated with significant short- and long-term increases in breast cancer mortality, while increases in PSEH are associated with reductions in breast cancer mortality. Initiatives that bolster employment and maintain total health-care expenditure may help minimize increases in breast cancer mortality during economic crises.

The global economic downturn has been associated with increased unemployment in many countries. Insights into the impact of unemployment on specific health conditions remain limited. We determined the association between unemployment and prostate cancer mortality in members of the Organisation for Economic Co-operation and Development (OECD). We used multivariate regression analysis to assess the association between changes in unemployment and prostate cancer mortality in OECD member states between 1990 and 2009. Country-specific differences in healthcare infrastructure, population structure, and population size were controlled for and lag analyses conducted. Several robustness checks were also performed. Time trend analyses were used to predict the number of excess deaths from prostate cancer following the 2008 global recession. Between 1990 and 2009, a 1% rise in unemployment was associated with an increase in prostate cancer mortality. Lag analysis showed a continued increase in mortality years after unemployment rises. The association between unemployment and prostate cancer mortality remained significant in robustness checks with 46 controls. Eight of the 21 OECD countries for which a time trend analysis was conducted, exhibited an estimated excess of prostate cancer deaths in at least one of 2008, 2009, or 2010, based on 2000–2007 trends. Rises in unemployment are associated with significant increases in prostate cancer mortality. Initiatives that bolster employment may help to minimise prostate cancer mortality during times of economic hardship.

Objectives We sought to determine the association between changes in unemployment, healthcare spending and stomach cancer mortality. Methods Multivariate regression analysis was used to assess how changes in unemployment and public-sector expenditure on healthcare (PSEH) varied with stomach cancer mortality in 25 member states of the European Union from 1981 to 2009. Country-specific differences in healthcare infrastructure and demographics were controlled for 1- to 5-year time-lag analyses and robustness checks were carried out. Results A 1% increase in unemployment was associated with a significant increase in stomach cancer mortality in both men and women [men: coefficient (R)=0.1080, 95% confidence interval (CI)=0.0470–0.1690, P=0.0006; women: R=0.0488, 95% CI=0.0168–0.0809, P=0.0029]. A 1% increase in PSEH was associated with a significant decrease in stomach cancer mortality (men: R=–0.0009, 95% CI=–0.0013 to –0.005, P<0.0001; women: R=–0.0004, 95% CI=–0.0007 to –0.0001, P=0.0054). The associations remained when economic factors, urbanization, nutrition and alcohol intake were controlled for, but not when healthcare resources were controlled for. Time-lag analysis showed that the largest changes in mortality occurred 3–4 years after any changes in either unemployment or PSEH. Conclusion Increases in unemployment are associated with a significant increase in stomach cancer mortality. Stomach cancer mortality is also affected by public-sector healthcare spending. Initiatives that bolster employment and maintain public-sector healthcare expenditure may help to minimize increases in stomach cancer mortality during economic downturns.

Objectives The relative health effects of changes in unemployment, inflation and gross domestic product (GDP) per capita on population health have not been assessed. We aimed to determine the effect of changes in these economic measures on mortality metrics across Latin America. Design Ecological study. Setting Latin America (21 countries), 1981–2010. Outcome measures Uses multivariate regression analysis to assess the effects of changes in unemployment, inflation and GDP per capita on 5 mortality indicators across 21 countries in Latin America, 1981–2010. Country-specific differences in healthcare infrastructure, population structure and population size were controlled for. Results Between 1981 and 2010, a 1% rise in unemployment was associated with statistically significant deteriorations (p<0.05) in 5 population health outcomes, with largest deteriorations in 1–5 years of age and male adult mortality rates (1.14 and 0.53 rises per 1000 deaths respectively). A 1% rise in inflation rate was associated with significant deteriorations (p<0.05) in 4 population health outcomes, with the largest deterioration in male adult mortality rate (0.0033 rise per 1000 deaths). Lag analysis showed that 5 years after rises in unemployment and inflation, significant deteriorations (p<0.05) occurred in 3 and 5 mortality metrics, respectively. A 1% rise in GDP per capita was associated with no significant deteriorations in population health outcomes either in the short or long term. β coefficient comparisons indicated that the effect of unemployment increases was substantially greater than that of changes in GDP per capita or inflation. Conclusions Rises in unemployment and inflation are associated with long-lasting deteriorations in several population health outcomes. Unemployment exerted much larger effects on health than inflation. In contrast, changes in GDP per capita had almost no association with the explored health outcomes. Contrary to neoclassical development economics, policymakers should prioritise amelioration of unemployment if population health outcomes are to be optimised.
