Resumen
The objective was to analyze the association of changes in pre-dialysis systolic and diastolic blood pressure with
air temperature in a municipality in the Brazilian Pantanal, a tropical climate area. Longitudinal panel study, with
analysis of mixed effects models of 133 hemodialysis patients in the city of C aceres-Mato Grosso in 2014. Air
temperature showed an inverse association with pre-dialysis systolic and diastolic blood pressure. With each
increase of 1 C in the mean air temperature, the pre-dialysis systolic blood pressure decreases -0.730mmHg (p
0.000) and the pre-dialysis diastolic blood pressure decreases -0.280mmHg (p 0.000). The estimated effect was
greater for systolic blood pressure, but both pre-dialysis blood pressure measures are reduced with an increase in
lag (up to two days), even when adjusted for relative air humidity. Air temperature is determinant for changes in
pre-dialysis systolic and diastolic blood pressure in hemodialysis patients. The temperature effect was greater for
systolic blood pressure than for diastolic blood pressure.
