To observe the facial spectrum and color of different points, the positions of heart, liver, spleen, lung and kidney of traditional Chinese medicine reflecting on the face, in healthy participants and those with a sub-health status, so as to provide an objective basis for health evaluation.
The health condition of 470 subjects without acute and chronic conditions was assessed using the Health Evaluating Questionnaire H20 V2009. The subjects were diagnosed with health (more than 80 score) or sub-health (score between 60 and 80) status according to the questionnaire score. The subjects with a subhealth status were also analyzed using the five-viscera syndrome differentiation of traditional Chinese medicine using the form for collecting information according to the four examinations. Then for gathering the facial color information, CIE Lab and C values and reflections of wavelengths ranged from 400 to 700 nm were measured using a CM-2600D spectrophotometer on 8 points of the face, including the frontal part, glabella, nose, mandible, two cheeks and eyelids.
L value of the sub-health group was higher than that of the health group (P<0.05), and a, b and C values were lower than those of the health group (P<0.05), suggesting that the facial complexion of the sub-health group was pale/whiter than the health group. The reflectance rates of wavelengths (from 400 to 550 nm) of the sub-health group were higher than those of the health group (P<0.05), which suggested that the facial complexion of the sub-health group was partially green. The a, b and C values of the forehead, glabella and nose of subjects in the sub-health group were apparently different from the health subjects. L values of five-viscera types were significantly different from people of a health status (P<0.05). There were some differences in color values among the five-viscera groups: lung group's color values were significantly different from the others in terms of a, b and C values. The spectral reflectance of different viscera groups of the sub-health group also showed certain differences: reflectance of wavelengths at 400 to 490 nm in the lung group and at 520 to 580 nm in the spleen group showed significant difference from the other groups, and the lung group was lower and the spleen group was higher than the others.
There are some differences in facial spectrum and color in different sites of the face in sub-health status of different viscera syndrome types, which can provide an objective basis for health evaluation.
观察健康人群和亚健康人群面部不同穴位的光谱及颜色，以及中医心、肝、脾、肺、肾在面部的反映部位，为健康评估提供客观依据。
采用健康评估问卷H20 V2009对470例无急慢性疾病的受试者进行健康状况评估。根据问卷得分将受试者诊断为健康（得分大于80分）或亚健康（得分在60至80分之间）状态。对亚健康状态的受试者还采用中医五脏辨证方法，根据四诊收集信息的表格进行分析。然后为收集面部颜色信息，使用CM - 2600D分光光度计在面部8个部位，包括额部、眉间、鼻部、下颌、两颊和眼睑，测量CIE Lab和C值以及400至700nm波长的反射率。
亚健康组的L值高于健康组（P<0.05），a、b和C值低于健康组（P<0.05），表明亚健康组的面色比健康组苍白/更白。亚健康组400至550nm波长的反射率高于健康组（P<0.05），这表明亚健康组的面色部分呈绿色。亚健康组受试者的额部、眉间和鼻部的a、b和C值与健康受试者明显不同。五脏类型的L值与健康状态的人有显著差异（P<0.05）。五脏组之间的颜色值存在一些差异：肺组的颜色值在a、b和C值方面与其他组有显著差异。亚健康组不同脏腑组的光谱反射率也显示出一定差异：肺组400至490nm波长的反射率和脾组520至580nm波长的反射率与其他组有显著差异，肺组低于其他组，脾组高于其他组。
不同脏腑证候类型的亚健康状态下，面部不同部位的光谱和颜色存在一些差异，可为健康评估提供客观依据。
