The Concept of Sasang Health Index and Constitution-Based Health Assessment: An Integrative Model with Computerized Four Diagnosis Methods

Table 10

Changes of diagnostic variables associated with health degradation for each SC type.

SC type	Diagnostic component	Associated changes of diagnostic variables with health degradation
	Complexion	Increased brightness variance in the cheek (ChLD_Y_std) and decreased brightness in the nose (Nose_Y_avg)
	Pulse	Increased pulse depth (R_PDI) increased amplitude of the pulse wave within the pulse volume (L_PPW_PVI), decreased proportion of the area of the pulse wave during the diastolic period (L_Adias_HR75), and decreased PSD in a high harmonic frequency (L_PSD_w3_w1)
TE	Skin	Decreased wrinkle density (Wrinkle_hand)
	Voice	Increased frequency variation (aPPQ) increased bandwidths of the 1st and 2nd formants (eBW1, oBW2), and shift of the fundamental frequency at the 10th percentile into a lower frequency (sF10)
	Questionnaire	Decreased exercise capability, worsened sleep habits, and decreased tendency toward extroversion and broad-mindedness
	Complexion	Increased brightness variance in the forehead (FhW_Y_std) increased variances of blueness and redness in the cheek (ChRU_Cb_std, ChLU_Cr_std)
SE	Pulse	Increased pulse depth (L_PDI)
	Questionnaire	Low self-estimated health state, low exercise capability, indigestion, worsened sleep habits, and increased unhealthy period
SY	Complexion	Increased blueness variance in the forehead (FhR_Cb_std) and increased brightness variance in the cheek (ChRD_Y_std)
	Skin	Decreased elasticity (E)
	Voice	Increased ratio of the frequency intervals between a high to the median and the median to a low fundamental frequency (sFHL)
	Questionnaire	Low self-estimated health state, improved eating habits, and increased tendency toward extroversion and broad-mindedness
