Abstract

We examined the seasonal variation of brown adipose tissue vascular density (BAT-d), which was estimated using total hemoglobin concentration in the supraclavicular region, in healthy subjects (9 men and 10 women) from November 2016 to November 2017. Generally, BAT-d was significantly higher in winter than in summer for all subjects. Although monthly BAT-d was significantly different for a year, no statistically significant difference was found from November to April. In conclusion, there was a seasonal variation of BAT-d from summer to winter and a lack of variation during late fall to the middle of spring among healthy subjects.
