Lower core body temperature and greater body fat are components of a human thrifty phenotype

Does body adiposity index evaluate percentage of body fat?

Introduction: The purpose of the present study was to determine whether the novel marker, body adiposity index (BAI), is accurate to measure percentage of body fat (PBF). Materials and methods: Seventy-eight males were undergone anthropometric examination. PBF was calculated by BAI and measured using InBody 3.0.   Results: Significant correlation was found between BAI and PBF (r = 0.751; P < ...

Implications of Changes in Core Body Temperature

Dairy farmers and veterinarians have used body temperatures, most commonly rectal temperatures, to detect and manage febrile disease and changes in the state of cows (estrus and onset of calving) for many years. Mastitis, pneumonia, metritis, lameness, estrus, onset of parturition, heat stress, and subacute ruminal acidosis (SARA) are among the physiological conditions potentially correlated wi...

Lower body temperature in sleeping supine infants.

Night time rectal temperature recordings were made from 103 infants sleeping in their own home in different sleeping positions. In most cases sleeping position was verified by video monitoring throughout the night. In the period before an adult-like night time body temperature pattern appeared there was no significant effect of sleeping position upon night time body temperature, in line with pr...

Endogenous and exogenous components in the circadian variation of core body temperature in humans

Endogenous and exogenous components in the circadian variation of core body temperature in humans.

Core body temperature is predominantly modulated by endogenous and exogenous components. In the present study we tested whether these two components can be reliably assessed in a protocol which lasts for only 120 h. In this so-called forced desynchrony protocol, 12 healthy male subjects (age 23.7 +/- 1.4 y) were subjected one by one to an artificial light/dark cycle of 20 h (10 lux vs. darkness...
