Title: Cause specific infant mortality and ambient temperature: A time-series study of Sweden, 1868-1893.
Abstract: Infants are vulnerable to climate variability, especially in pre-industrial societies where infant mortality was high. However, little is known about how extreme temperature affects cause-specific infant mortality in high mortality settings. We investigate the association between ambient temperature and cause-specific infant mortality.
Parish register data from the Sundsvall region in Northern Sweden covering the period 1860-1900 were used in combination with daily temperature data from Härnösand. Mortality due to water- and food-born diseases, and infectious diseases were modelled as a function of mean temperature exposure in the previous days using Poisson time-series analysis. Preliminary results show a U-shaped association to all-cause mortality, a negative association to mortality from airborne infectious diseases and a positive association to waterborne infectious mortality (WFID). Only WFID show an association to temperature when adjusting for seasonality.
