  abstract = {{M}easurements of body composition are crucial in identifying {HIV}-infected patients at risk of malnutrition. {N}o information is available on the validity of indirect body composition methods in {A}frican {HIV}-infected outpatients. {O}ur first aim was to test the validity of fifteen published equations, developed in whites, {A}frican-{A}mericans and/or {A}fricans who were or not {HIV}-infected, for predicting total body water ({TBW}) from bioelectrical impedance analysis ({BIA}) in {HIV}-infected patients. {T}he second aim was to develop specific predictive equations. {T}hirty-four {HIV}-infected patients without antiretroviral treatment and oedema at the beginning of the study (age 39 (si) 7) years, {BMI} 18.7 ({SD} 3.7) kg/m(2), {TBW} 30.4 ({SD} 7.2) kg) were measured at inclusion then 3 and 6 months later. {I}n the resulting eighty-eight measurements, we compared {TBW} values predicted from {BIA} to those measured by {H}-2 dilution. {R}ange of bias values was 0.1-4.3kg, and errors showed acceptable values (2.2-3.4kg) for fourteen equations and a high value (10.4) for one equation. {T}wo equations developed in non-{HIV}-infected subjects showed non-significant bias and could be used in {A}frican {HIV}-infected patients. {I}n the other cases, poor agreement indicated a lack of validity. {S}pecific equations developed from our sample showed a higher precision of {TBW} prediction when using resistance at 1000 k{H}z (1.7 kg) than at 50 k{H}z (2.3 kg), this latter precision being similar to that of the valid published equations (2.3 and 2.8 kg). {T}he valid published or developed predictive equations should be cross-validated in large independent samples of {A}frican {HIV}-infected patients.},
