Sagittal abdominal diameter (SAD) is a measure of visceral obesity, the amount of fat in the gut region. SAD is the distance from the small of the back to the upper abdomen. SAD may be measured when standing or supine. SAD may be measured at any point from the narrowest point between the last rib and the iliac crests to the midpoint of the iliac crests. SAD is a strong predictor of coronary disease, with higher values indicating increased risk independent of BMI.

| - 矢状腹径(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。矢状腹径可以在站立時量測,也可以在仰臥時量測。矢状腹径可以由任何一點量測,從最后肋骨和髂嵴之間的最窄處,到髂嵴的中點皆可。 矢状腹径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。 對於有正常身高體重指數的人,其矢状腹径需小於25厘米(9.8英寸)。矢状腹径和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。男性在四十歲時,若矢状腹径大於25 cm,其在三十年後罹患阿兹海默病的比例也顯著提高。一篇的論文也將腹部脂肪連結到較小的大腦容量。 另一個相關的量測是(SAH),是在時腹部的高度。SAH法較容易自我監控,但因為重力的關係,其數值會比較小,數值不能直接和矢状腹径比較。 (zh)

| - Sagittal abdominal diameter (SAD) is a measure of visceral obesity, the amount of fat in the gut region. SAD is the distance from the small of the back to the upper abdomen. SAD may be measured when standing or supine. SAD may be measured at any point from the narrowest point between the last rib and the iliac crests to the midpoint of the iliac crests. SAD is a strong predictor of coronary disease, with higher values indicating increased risk independent of BMI. For persons of normal BMI, SAD should be under 25 centimetres (9.8 in). The amount this measure exceeds 30 centimetres (12 in) correlates to increased cardiovascular risk and insulin resistance. SAD measure of men in their 40s, greater than 25 cm, also predicts significantly higher risk of Alzheimer's disease 30 years later. An article in Annals of Neurology links visceral fat to lower brain volume. (en)
