Concurrent validity of supraclavicular skin temperature measured with iButtons and infrared thermography as a surrogate marker of brown adipose tissue. J Therm Biol. 2019 May;82:186-196.0306-4565http://hdl.handle.net/10668/14020Brown adipose tissue (BAT) thermogenic activity is commonly assessed with a positron emission tomography with computed tomography scan (PET/CT). This technique has several limitations and alternative techniques are needed. Supraclavicular skin temperature measured with iButtons and infrared thermography (IRT) has been proposed as an indirect marker of BAT activity. We studied the concurrent validity of skin temperature measured with iButtons vs. IRT and the association of supraclavicular skin temperature measured with iButtons and IRT with BAT. We measured skin temperature upon a shivering threshold test with iButtons and IRT in 6 different regions in 12 participants (n = 2 men). On a separate day, we determined supraclavicular skin temperature with an iButton and IRT after 2 h of a personalized cooling protocol. Thereafter, we quantified BAT volume and activity by PET/CT. We observed that the absolute differences between the devices were statistically different from 0 (all P enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Skin temperatureThermoregulationbrown fatAdipose Tissue, BrownAdolescentAdultFemaleFluorodeoxyglucose F18HumansInfrared RaysMalePositron Emission Tomography Computed TomographySkin TemperatureThermogenesisThermographyYoung Adultresearch article31128647open accessAdolescenteAdultoAdultoAdulto jovenFemeninoFluorodesoxiglucosa F18HumanosMasculinoRayos infrarrojosTejido adiposo pardoTemperatura cutáneaTermografíaTermogénesisTomografía computarizada por tomografía de emisión de positrones10.1016/j.jtherbio.2019.04.009https://doi.org/10.1016/j.jtherbio.2019.04.009
