Summary Sagittal abdominal diameter ( SAD ; ‘abdominal height’ measured in supine position) may improve upon conventional anthropometry for predicting incident cardiometabolic diseases. However, the SAD is used infrequently by practitioners and epidemiologists. A representative survey of Finnish adults in 2000–2001 collected body measurements including SAD (by sliding‐beam calliper) using standardized protocols. Sampled non‐pregnant adults (ages 30+ years; 79% participation) provided 6123 SAD measurements from 80 health centre districts. Through stratified, complex survey design, these data represented 2.86 million adults at ages 30+ years. SAD ranged from 13.5 to 38.0 cm, with a population mean (standard error) of 21.7 (0.05) cm and median (interquartile range) of 21.0 (19.1–23.4). Median SAD was higher at ages 50+ years compared with ages 30–49 both for men (22.4 [20.5–24.6] vs. 20.8 [19.3–22.7]) and women (21.7 [19.6–23.9] vs. 19.4 [17.8–21.4]). The SAD /height ratio was similar (0.118) for both sexes at 30–39 years, rising more steeply with age for women than men. Attaining only a basic education, compared with a high level, was associated with increased mean (95% confidence interval) SADs for men (22.6 [22.3–22.8] vs. 22.0 [21.7–22.2]) and women (21.8 [21.5–22.0] vs. 20.6 [20.4–20.8]). F inland's early experience with nationally representative SAD measurements provides normative reference values and physiological insights useful for investigations of cardiometabolic risk.
