The impact of aircraft noise on health is of growing concern. We investigated the relationship between this exposure and mortality from cardiovascular disease, coronary heart disease, myocardial infarction, and stroke. We performed an ecological study on 161 communes (commune being the smallest administrative unit in France) close to the following three major French airports: Paris-Charles de Gaulle, Lyon Saint-Exupéry, and Toulouse-Blagnac. The mortality data were provided by the French Center on Medical Causes of Death for the period 2007-2010. Based on the data provided by the French Civil Aviation Authority, a weighted average exposure to aircraft noise (Lden AEI) was computed at the commune level. A Poisson regression model with commune-specific random intercepts, adjusted for potential confounding factors including air pollution, was used to investigate the association between mortality rates and Lden AEI. Positive associations were observed between Lden AEI and mortality from cardiovascular disease [adjusted mortality rate ratio (MRR) per 10 dB(A) increase in Lden AEI = 1.18; 95% confidence interval (CI): 1.11-1.25], coronary heart disease [MRR = 1.24 (1.12-1.36)], and myocardial infarction [MRR = 1.28 (1.11-1.46]. Stroke mortality was more weakly associated with Lden AEI [MRR = 1.08 (0.97-1.21]. These significant associations were not attenuated after the adjustment for air pollution. The present ecological study supports the hypothesis of an association between aircraft noise exposure and mortality from cardiovascular disease, coronary heart disease, and myocardial infarction. However, the potential for ecological bias and the possibility that this association could be due to residual confounding cannot be excluded.

BackgroundAlthough several cross-sectional studies have shown that aircraft noise exposure was associated with an increased risk of hypertension, a limited number of longitudinal studies have addressed this issue. This study is part of the DEBATS (Discussion on the health effect of aircraft noise) research programme and aimed to investigate the association between aircraft noise exposure and the incidence of hypertension.MethodsIn 2013, 1244 adults living near three major French airports were included in this longitudinal study. Systolic and diastolic blood pressure, as well as demographic and lifestyle factors, were collected at baseline and after 2 and 4 years of follow-up during face-to-face interviews. Exposure to aircraft noise was estimated for each participant’s home address using noise maps. Statistical analyses were performed using mixed Poisson and linear regression models adjusted for potential confounding factors.ResultsA 10 dB(A) increase in aircraft noise levels in terms of Lden was associated with a higher incidence of hypertension (incidence rate ratio (IRR)=1.36, 95% CI 1.02 to 1.82). The association was also significant for Lday (IRR 1.41, 95% CI 1.07; to 1.85) and Lnight (IRR 1.31, 95% CI 1.01 to 1.71). Systolic and diastolic blood pressure increased with all noise indicators.ConclusionThese results strengthen those obtained from the cross-sectional analysis of the data collected at the time of inclusion in DEBATS, as well as those from previous studies conducted in other countries. Hence, they support the hypothesis that aircraft noise exposure may be considered as a risk factor for hypertension.

Background: Subgroups of patients registered on a kidney transplant waiting list have higher than usual mortality levels. This study used data from the French Renal Epidemiology and Information Network (REIN) Registry to quantify the impact over time of various comorbidities on the excess risk of death among patients on the waiting list. Methods: Lexis diagrams were used to analyze time since onset of end-stage renal disease and time since registration on the waiting list. The number of excess deaths was calculated by comparison with the number of expected deaths in the general population of the same age and sex. Results: During 45,013 person-years of follow-up, 7,224 patients died, 5,956 (82%) more than expected relative to the general population. There were 101 deaths among wait-listed dialysis patients, 76 more than expected. The excess risk of death increased by 45% per additional year on the waiting list (18-79%, p = 0.0005). Time from end-stage renal disease onset until list registration (p = 0.004), time since registration (p < 0.001), age >65 years (p = 0.008), the presence of a primary renal disease (p = 0.028), and the number of comorbidities (p = 0.035) were independent predictors of death while on the waiting list. Conclusions: The excess risk of death while on the waiting list increased faster in patients with comorbidities. These results require consideration of ways to accelerate access to transplantation in high-risk patients.
