Diurnal temperature variation and the implications for diagnosis and infectious disease screening: a population-based study.
This study’s objective was to describe individual variation in diurnal temperature patterns during episodes of febrile activity using millions of recorded temperatures and evaluate the probability of recording a fever by sex and for different age groups. The authors used timestamped deidentified temperature readings from thermometers across the US to construct illness episodes where continuous periods of activity in a single user included a febrile reading. They modeled the mean temperature recorded and probability of registering a fever across the course of a day using sinusoidal regression models while accounting for user age and sex. They then estimated the probability of recording a fever by time of day for children, working-age adults, and older adults. They found wide variation in body temperatures over the course of a day and across individual characteristics, with temperature patterns differing between men and women, and average temperatures declining for older age groups. There was a wide variation of the likelihood of fever detection by the time of day and by an individual’s age or sex.
