In the first of two studies published online October 8, 2013 in BMJ, Dr Anna L Hansell (Imperial College London, UK) and colleagues assessed hospital admissions for 3.6 million people living near Heathrow Airport[SUP][1][/SUP]. Their paper linked daytime and nighttime aircraft noise and hospital visits for stroke, coronary heart disease, and cardiovascular disease by comparing residents in the noisiest areas with those living farther from the airport.
They found that, after adjustment for confounders, high-noise areas (>63 dB) had significantly increased risks for all three diagnostic codes as compared with the quieter areas (<51 dB).
