  abstract = {{O}bjectives: {C}humlea's formulas are a way of predicting height from knee height ({KH}t), including among individuals >60 y of age who cannot stand upright. {H}owever, the formulas were developed with white and {A}frican {A}merican people and have not yet been validated in native {A}fricans >60 y of age. {T}he aims of the study were to assess {C}humlea's formulas in older people in central {A}frica and to propose a new validated formula for the same population.{M}ethods: {H}eight ({MH}t) and {KH}t were measured in a population of individuals >65 y of age from the {R}epublic of {C}ongo and the central {A}frican {R}epublic. {P}redicted height ({PH}t) was calculated using {C}humlea's formulas for the {A}merican black population ({CBP}) and for whites ({CC}). {T}he percentages of accurate predictions (§5 cm) were compared between {MH}t and {PH}t. {A} new formula was estimated after randomization in a derivation sample (n = 877) and assessed for accuracy in a validation sample (n = 877). {R}esults: {T}he study included 1754 individuals. {P}rediction was accurate (§5 cm) in 66.8% and 63.2% of {CBP} and {CC}, respectively. {O}verestimation was as high as 24.1% and 29%, respectively. {B}ecause an overestimation is unacceptable in clinical practice and population surveys, a new formula was proposed: height (cm) = 72.75 + (1.86 £ {KH}t [cm])  (0.13 £ age [y]) + 3.41 £ sex (0: women; 1: men). {T}his new formula significantly increases accuracy (71.3%) and decreases overestimation (14.7%). {T}he nutritional status based on body mass index did not differ with the {MH}t and the {PH}t by the new formula. {C}onclusion: {C}humlea's formulas provided a poor estimate of height in this population sample. {T}he proposed formula more accurately estimates height in older native {A}fricans. {T}his formula should be tested in other sub-{S}aharan {A}frican countries to extend its use in clinical practice and in future studies.},
