Prediction of Areal Bone Mineral Density and Bone Mineral Content in Children and Adolescents Living With HIV Based on Anthropometric Variables

摘要: Abstract Children and adolescents living with HIV have low bone mass for age. There are reliable accurate methods evaluation of mass, however, alternative necessary, especially, application in limited-resource scenarios. Anthropometry is a noninvasive cost method that can predict healthy youths. The aim the study was to develop predictive equations mineral content density children based on anthropometric variables. Forty-eight both sexes (24 females) from 7 17 years, greater Florianopolis area, Santa Catarina, Brazil, who were under clinical follow-up at "Hospital Infantil Joana de Gusmao", participated study. Dual-energy X-ray absorptiometry used evaluate whole-body (BMC) areal (aBMD). Height, body weight, diameters, arm circumference, triceps skinfold measured index muscle area calculated. Multiple regression models fitted BMC aBMD, using backward selection ( p  ≥ 0.05). Two high R 2 values (84%–94%) developed. Model 1 estimate aBMD [Y = −0.1450124 + (height × 0.0033807) + (age 0.0146381) + (body 0.0158838) + (skin color 0.0421068)], model [Y = 1095.1 + (body weight 45.66973) + (age 31.36516) + (arm circumference −53.27204) + (femoral diameter −9.594018)].The anthropometry provided estimates be useful monitor human immunodeficiency virus where limited resources available.
