AB Brown adipose tissue (BAT) thermogenic activity is commonly assessed with a positron emission tomographywith computed tomography scan (PET/CT). This technique has several limitations and alternative techniques areneeded. Supraclavicular skin temperature measured with iButtons and infrared thermography (IRT) has beenproposed as an indirect marker of BAT activity. We studied the concurrent validity of skin temperature measuredwith iButtons vs. IRT and the association of supraclavicular skin temperature measured with iButtons and IRTwith BAT. We measured skin temperature upon a shivering threshold test with iButtons and IRT in 6 differentregions in 12 participants (n = 2 men). On a separate day, we determined supraclavicular skin temperature withan iButton and IRT after 2 h of a personalized cooling protocol. Thereafter, we quantified BAT volume andactivity by PET/CT. We observed that the absolute differences between the devices were statistically differentfrom 0 (all P < 0.05) after the shivering threshold test. Moreover, we did not find any association betweensupraclavicular skin temperature measured with iButtons or IRT and BAT 18F-FDG activity (r = −0.213;P = 0.530 and r = −0.079; P = 0.817). However, we observed a negative association of supraclavicular skintemperature measured by IRT with BAT 18F-FDG volume (r = −0.764; P = 0.006), but not with supraclavicularskin temperature measured with iButtons (r = −0.546; P = 0.082). In light of these results, we concluded thatthe measurement of skin temperature obtained by iButtons and IRT are not comparable. Furthermore, it seemsthat supraclavicular skin temperature is not associated with BAT 18F-FDG activity, but it appears to be negativelyassociated with BAT 18F-FDG volume in the case of IRT.
