dc.description.abstractGENERALLY, BODY SURFACE AREA (BSA) CHANGES SIGNIFICANTLY DURING GROWTH AND MATURATION. THESE INCREASES PORTEND A POSSIBLE RELATIONSHIP BETWEEN BODY SIZE AS DETERMINED BY BSA WITH MATURATIONAL STATUS IN CHILDREN AND ADOLESCENTS. OBJECTIVE: TO DETERMINE THE RELATIONSHIP BETWEEN MATURITY STATUS (MS) OBTAINED BY NON-INVASIVE ANTHROPOMETRIC METHODS AND BODY SURFACE AREA (BSA) IN CHILDREN AND ADOLESCENTS OF BOTH SEXES IN A REGIONAL POPULATION OF CHILE. ADDITIONALLY, WE SOUGHT TO VERIFY THE TYPE OF LINEAR OR NONLINEAR RELATIONSHIP BETWEEN MS AND BSA IN BOTH SEXES. METHODS: A DESCRIPTIVE (CROSS-SECTIONAL) STUDY WAS DESIGNED IN 950 CHILDREN AND ADOLESCENTS OF BOTH SEXES (539 MALES AND 411 FEMALES). THE AGE RANGE RANGED FROM 6.0 TO 17.9 YEARS. ANTHROPOMETRIC MEASUREMENTS WERE EVALUATED: BODY WEIGHT, STANDING HEIGHT, SITTING HEIGHT. MS WAS ASSESSED BY MEANS OF TWO NON-INVASIVE ANTHROPOMETRIC TECHNIQUES. BOTH TECHNIQUES PREDICT PEAK YEARS OF GROWTH VELOCITY (APHV) THROUGH A REGRESSION EQUATION FOR EACH SEX. BSA (M2) WAS ESTIMATED BY MEANS OF THE HAYCOCK EQUATION. RESULTS: THE R2 IN THE LINEAR MODEL IS RELATIVELY LOWER (R2?=?0.80 TO 0.89 IN MALES AND 0.74 TO 0.66 IN FEMALES) IN RELATION TO THE NONLINEAR QUADRATIC MODEL (R2?=?0.81 IN MALES AND 0.76 TO 0.69). THE QUADRATIC NONLINEAR QUADRATIC MODEL REFLECTED AN ADEQUATE FIT (RMSE) FOR THE DATA SET, BEING IN MEN (RMSE?=?1.080 AND 1.125), WHILE IN WOMEN (RMSE?=?1.779 AND 1.479). CONCLUSION: BSA IS POSITIVELY ASSOCIATED WITH MS DETERMINED BY TWO NON-INVASIVE METHODS IN CHILEAN CHILDREN AND ADOLESCENTS: THE NONLINEAR QUADRATIC MODEL WAS A BETTER FIT TO THE DATA DISTRIBUTION. THE RESULTS SUGGEST THE USE OF BSA AS A POSSIBLE PREDICTOR OF MATURITY STATUS IN CHILEAN YOUTH.
