Risk of cardiovascular mortality, stroke and coronary heart mortality associated with aircraft noise around Congonhas airport, Sao Paulo, Brazil: a small-area study.

ABSTRACT:

Background

Noise pollution is increasingly recognised as a public health hazard, yet limited evidence is available from low- and middle-income countries (LMIC), particularly for specific sources. Here, we investigated the association between day-night average (L_dn) aircraft noise and the risk of death due to cardiovascular disease (CVD), stroke and coronary heart disease (CHD) at small-area level around São Paulo's Congonhas airport, Brazil during the period 2011-2016.

Methods

We selected 3259 census tracts across 16 districts partially or entirely exposed to ≥50 dB aircraft noise levels around the Congonhas airport, using pre-modelled 5 dB L_dn noise  bands (≤50 dB to > 65 dB). We estimated the average noise exposure per census tract using area-weightin
