“…Since predictive formulas specifically tested in Italian population samples are not available at present, this study verified the extent of applicability of predictive measurements of stature by the Chumlea and Guo (12) equations in an elderly population. We chose this method for its wide use in the clinical setting and in anthropometric studies, which demonstrated a strong correlation between standing stature and knee height in the recumbent position (2,19). Comparing measured and derived stature, our study confirmed the applicability of the predicting equation in this older, rural population of central Italy.…”

We determined the applicability of deriving the stature from knee height in an older Italian population, and, in the same population, we assessed longitudinally the change in stature over a 6-year interval. The standing stature and knee height in a supine position were measured in the entire home-dwelling older (65 + years) population of a small Italian town (N = 606). Stature measured in 1989 and in 1995 was used to assess longitudinal changes in 258 subjects of the same population. Stature derived from knee height was greater than measured stature in this population and in the two sexes. This difference disappeared when subjects with evident kyphosis were excluded. From 1989 to 1995, stature decreased by 1.7+/-3.0 cm, with women showing a larger decrement than men. Stature estimated from knee height is more accurate than measured stature in subjects with kyphosis. In accordance with previous studies, stature decreases with aging, and such height loss is greater in women than in men.

“…To our knowledge no other published data have been analysed in this way, however, the mean difference between standing height and arm‐span found by Kwok (1991) is 6.05 cm, which is similar to our findings. Murphy et al . (1991) found a mean difference between standing height and height estimated from knee height as 4.5 cm, much larger than our results.…”

The results showed that demi-span and half arm-span could be measured in the largest proportions of our population, 75.6 and 72.3%, respectively. The correlation coefficients were high for all three estimates of height, r = 0.86 for demi-span, r = 0.87 for arm-span, and r = 0.89 for knee height (P < 0.0001 for all three). However, agreement analysis demonstrated very poor agreement between standing height and all the methods of estimation. The mean differences were 4.33 cm for demi-span, 7.04 cm for arm-span and -0.6 cm for knee height.

“…1 Although the Health and Retirement Study (HRS) developed a protocol for obtaining in-home wall height, 2 to our knowledge it has not been validated. The present study evaluated the performance of wall height 2 and knee height 3–6 as surrogate measures of stadiometer height among older adults.…”
