Avoidable Deaths

Health effects related to exposure to air pollution such as ozone (O3) have been documented. The World Health Organization has recommended the use of the Sum of O3 Means Over 35 ppb (SOMO35) to perform Health Impact Assessments (HIA) for long-term exposure to O3. We estimated the avoidable mortality associated with long-term exposure to tropospheric O3 in 14 cities in Mexico using information for 2015. The economic valuation of avoidable deaths related to SOMO35 exposure was performed using the willingness to pay (WTP) and human capital (HC) approaches. We estimated that 627 deaths (95% uncertainty interval (UI): 227–1051) from respiratory diseases associated with the exposure to O3 would have been avoided in people over 30 years in the study area, which confirms the public health impacts of ambient air pollution. The avoidable deaths account for almost 1400 million USD under the WTP approach, whilst the HC method yielded a lost productivity estimate of 29.7 million USD due to premature deaths. Our findings represent the first evidence of the health impacts of O3 exposure in Mexico, using SOMO35 metrics.

Lockdown measures to limit the spread of Covid-19 in France in spring 2020 sharply reduced activities and lowered air-pollution concentrations. This study sought to determine the short- and long-term impacts on mortality in metropolitan France resulting from the temporary decrease in the population's exposure to air pollution. The reduction in exposure to air pollution was estimated by calculating the difference between modeled exposure of the population during the strict lockdown and the gradual lifting, and the simulated exposure that would have been observed in the absence of lockdown. A quantitative health impact assessment was used to estimate both the short-term impact of PM10 and NO2 reductions, and the long-term impact of PM2.5 and NO2 reductions on mortality. Reduced activities during the lockdown lowered NO2 and PM concentrations, resulting in about 2,300 deaths postponed for PM2.5 and nearly 1,200 for NO2, mainly due to avoided long-term effects. This study shows that, even in an unprecedented context that is certainly neither realistic nor desirable to improve air quality in the long run, public interventions appear to have a significant impact on health through reductions in air-pollution levels. In a long-term perspective, the study also reminds us that the total burden of air pollution on health remains a significant risk factor in France. Efforts to reduce ambient air pollution must thus be pursued sustainably for all sources of air pollution with suitably adapted but ambitious policies. Finally, the lockdown restrictions had other consequences, both positive and negative, on the population's health. These consequences highlight the need to conduct more integrated assessments of health impacts that include the multisectoral consequences of interventions, particularly in terms of population compliance with mitigating restrictions, behavior and mental health and, more broadly, climate change.

Background: Abnormal ankle-brachial index (ABI) is prospectively associated with coronary heart disease (CHD) independent of traditional Framingham risk scores (FRS) variables. Two-thirds of CHD events occur in individuals with lower FRS (<20%). Evaluating the role of supplemental risk assessment with ABI among those subjects may have significant public health impact. We explore prevalence of abnormal ABI among the low-intermediate risk US population according to sex, age and race. Methods: We included 5035 cardiovascular disease-free, nonpregnant, nondiabetic individuals aged from 40 to 79 years from the National Health and Nutrition Examination Survey 1999–2004, representing approximately 75 million US adults. FRS was used to estimate participants’ 10-year risk for CHD, and two risk categories were defined as low (> 6%) and intermediate (6% – < 20%). Individuals with risk estimates ≥ 20% were excluded from this analysis. Abnormal ABI was defined as ABI < 0.9. Participants were categorized into younger ages (40–64) and older ages (65–79). The number needed to screen (NNS), which is the number of people within each stratum that needed to be screened to detect one person with abnormal ABI was used to assess the yield of screening for ABI. Results: Mean age was 53.1 years, with 45% (2261/5035) male, 19% (978/5035) non-Hispanic Black. Weighted prevalence of an abnormal ABI was 1.63% (61/2261) in men and 3.78% (138/2774) in women, corresponding to 2.1 million US adults aged 40 and above. Abnormal ABI was observed in 0.4% (2/714) and 2.4% (59/1488) in men (NNS=357 and 26) of those with low and intermediate risk, and 2.8% (85/2248) and 9.4% (53/526) in women (NNS=26 and 10), respectively. Older participants have higher prevalence of abnormal ABI than younger both in men (4.4% (29/435) vs. 1.8% (32/1826), NNS=15 and 57) and women (7.5% (63/748) vs. 2.9% (75/2026), NNS=12 and 27). Non-Hispanic Blacks have higher prevalence of abnormal ABI than other races in men (Black: 3.1% (21/458) vs. White: 1.6% (29/1144) and others: 0.9% (11/659)) as well as in women (Black: 7.1% (40/520) vs. White: 3.7% (64/1379) and others: 2.3% (34/875)). Conclusions: Among individuals at low-intermediate predicted 10-year CHD risk in US population, we observed concordance between abnormal ABI prevalence and FRS risk strata. The yield of screening and possibility of identifying abnormal ABI cases is highest in those with intermediate risk, especially older ages, non-Hispanic blacks and females.
