矢狀腹徑
矢狀腹徑（SAD）是一種量測腹部脂肪組織的方式，是背部到上腹部之間的厚度。矢狀腹徑可以在站立時量測[1]，也可以在仰臥時量測[2]。矢狀腹徑可以由任何一點量測，從最後肋骨和髂嵴之間的最窄處，到髂嵴的中點皆可[1][2][3]。
矢狀腹徑可以有效預測冠狀動脈疾病，其數值越高，其風險越高，此風險和身高體重指數無關[1]。
對於有正常身高體重指數的人，其矢狀腹徑需小於25厘米（9.8英寸）。矢狀腹徑和30厘米（12英寸）相減的數值和心血管疾病及胰島素抵抗有正相關[2]。男性在四十歲時，若矢狀腹徑大於25 cm，其在三十年後罹患阿茲海默病的比例也顯著提高[4]。一篇神經病學年鑑的論文也將腹部脂肪連結到較小的大腦容量[5]。
另一個相關的量測是仰臥腹部高度（SAH），是在仰臥時腹部的高度[6]。SAH法較容易自我監控，但因為重力的關係，其數值會比較小，數值不能直接和矢狀腹徑比較[來源請求]。
