The aim of this study was to establish the skin temperature (Tsk) thermal profile for the Brazilian population and to compare the differences between female and male Brazilian adults. A total of 117 female and 103 male were examined with a thermographic camera. The Tsk of 24 body regions of interest (ROI) were recorded and analyzed. Male Tsk results were compared to female and 10 ROI were evaluated with respect to the opposite side of the body (right vs. left) to identify the existence of significant contralateral Tsk differences (ΔTsk). When compared right to left, the largest contralateral ΔTsk was 0.3°C. The female vs. male analysis yielded significant differences (p<0.05) in 13 of the 24 ROI. Thigh regions, both ventral and dorsal, had the highest ΔTsk by sex (≈1.0°C). Tsk percentile below P5 or P10 and over P90 or P95 may be used to characterize hypothermia and hyperthermia states, respectively. Thermal patterns and Tsk tables were established for Brazilian adult men and women for each ROI. There is a low Tsk variation between sides of the body and gender differences were only significant for some ROIs.
本研究旨在建立巴西人群的皮肤温度（Tsk）热谱，并比较巴西成年男女之间的差异。共有 117 名女性和 103 名男性接受了热成像摄像机的检查。记录和分析了 24 个感兴趣的身体区域（ROI）的 Tsk。将男性 Tsk 结果与女性进行比较，并对 10 个 ROI 进行了身体左右两侧的对比（右侧与左侧），以确定是否存在明显的对侧 Tsk 差异（ΔTsk）。右侧与左侧相比，最大的对侧 ΔTsk 为 0.3°C。女性与男性的分析结果在 24 个 ROI 中的 13 个存在显著差异（p<0.05）。大腿区域，无论是腹侧还是背侧，性别差异最大（≈1.0°C）。Tsk 百分位数低于 P5 或 P10 以及高于 P90 或 P95 可分别用于描述低体温和高热状态。为每个 ROI 建立了巴西成年男性和女性的热图和 Tsk 表。身体两侧的 Tsk 变化很小，只有一些 ROI 存在性别差异。
