COMPARISON OF PERCEIVED WEIGHT AS IDEAL AGAINST IDEAL BODY WEIGHT FORMULAS AND BODY MASS INDEX OF 22 KG/M2 IN YOUNG ADULT WOMEN.

SUMMARY Introduction: Formulas of ideal body weight (IBW) including the body mass index (BMI) of 22 kg/m 2 are used under the assumption to provide a healthy weight. Objective: We compare the perceived ideal body weight (PIBW) with the calculated IBW by formulas and the BMI of 22. Methods: We recruited 705 women (20-25 y). Six common formulas and 2 published equations by our team were used. Results: Group regression analysis determined that including the frame size improves the agreement of formulas of Robinson et al, Hammond and Hamwi with the PIBW (p>0.05). Individually, the concordance analysis (higher % of differences 0.05). Individualmente, el analisis de concordancia (porcentaje mayor de diferencias <2 kg: PPI-PIF), determino que para un IMC <20 kg/m2 solo la formula de Faspyn 1 debe ajustarse por la complexion corporal, mientras que las formulas de Robinson et al, Hammond, Tokunaga (IMC de 22), Faspyn 2 (IMC de 22) y Broca, son equivalentes con el PPI en diferentes intervalos de IMC. Conclusiones: de acuerdo con el IMC percibido como sobrepeso (23.8 kg/m2) y percibido como ideal (21.1 kg/m2), las formulas de peso ideal y el IMC de 22 deben ser usados con precaucion en el diagnostico de peso ideal ya que no necesariamente representan un peso deseable o estetico.
