Effect modification by maximum temperature of the association between PM_2.5 and short-term cardiorespiratory mortality and emergency room visits in Lima, Peru, 2010-2016.

ABSTRACT:

Background

The health effects of fine particulate matter (PM_2.5) may be worse at higher temperatures.

Objective

To investigate temperature's effect on PM_2.5-mortality/morbidity associations in Lima, Peru.

Methods

Time-series regressions relating PM_2.5 and temperature to mortality and emergency room (ER) visits during 2010-2016. Daily PM_2.5 levels (assigned to 40 Lima districts) and daily maximum temperature (Lima-wide) were estimated based on ground monitors, remote sensing, and modeling. We analyzed all-cause, cardiovascular (ICD codes I00-I99), and respiratory (ICD codes J00-J99) mortality, and cardiovascular and respiratory causes for ER visits.

Results

The average PM_2.5 concentration was 20.9 µg/m³
