Associations between monthly temperature anomalies and mortality among children younger than five years in low- and middle-income countries.

ABSTRACT: This study examined associations between anomalous temperatures and under-five mortality (U5M) in low- and middle-income countries (LMICs). Between 1998 and 2019, data were collected on 1,745,132 live births across 56 LMICs. The median age was 27.0 months (interquartile range: 12.0, 43.0), and 51.0% were male. Monthly temperature anomalies were calculated as deviations from the long-term average temperature for the same calendar months. We developed a two-dimensional exposure-response function (ERF) based on a varying-coefficient model to examine the relationship between U5M and both long-term average temperatures and anomalous temperatures. Here we show, in the multicenter model, each 1 °C increase in positive temperature anomalies or decrease in negative temperature anomalies is associat
