Design: Cross-sectional study. BW perception was evaluated by the question, "Do you think you/your child are/is: severely wasted, wasted, normal weight, overweight, obese?" BI perception was evaluated using the Gardner scale. To evaluate reliability, BW and BI perceptions were reported twice, two weeks apart. To evaluate validity, the BW and BI perceptions were compared with WHO BMI Z-scores. Kappa and Kendall's tau-c coefficients were obtained. Setting: Public and private schools and high schools from six countries of South America (Argentina, Peru, Colombia, Uruguay, Chile, Brazil). Participants: Children aged 3-10 years (n 635) and adolescents aged 11-17 years (n 400). Results: Reliability of BW perception was fair in children's parents (k=0·337) and substantial in adolescents (k=0·709). Validity of BW perception was slight in children's parents (k=0·176) and fair in adolescents (k=0·268). When evaluating BI, most children were perceived by parents as having lower weight. Reliability of BI perception was slight in children's parents (k=0·124) and moderate in adolescents (k=0·599). Validity of BI perception was poor in children's parents (k=-0·018) and slight in adolescents (k=0·023). Conclusions: Reliability of BW and BI perceptions was higher in adolescents than in children's parents. Validity of BW perception was good among the parents of the children and adolescents with underweight and normal weight. 000078196 536__ $$9info:eu-repo/grantAgreement/ES/MICINN-FEDER/GENUD Research Group 000078196 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000078196 590__ $$a3.182$$b2019 000078196 591__ $$aPUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH$$b50 / 193 = 0.259$$c2019$$dQ2$$eT1 000078196 591__ $$aNUTRITION & DIETETICS$$b43 / 89 = 0.483$$c2019$$dQ2$$eT2 000078196 592__ $$a1.21$$b2019 000078196 593__ $$aMedicine (miscellaneous)$$c2019$$dQ1 000078196 593__ $$aPublic Health, Environmental and Occupational Health$$c2019$$dQ1 000078196 593__ $$aNutrition and Dietetics$$c2019$$dQ1 000078196 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000078196 700__ $$aRestrepo-Mesa, S.L. 000078196 700__ $$aAristizabal, J.C. 000078196 700__ $$aSkapino, E. 000078196 700__ $$aCollese, T.S. 000078196 700__ $$aAzzaretti, L.B. 000078196 700__ $$aNascimento-Junior, W.V. 000078196 700__ $$0(orcid)0000-0003-0454-653X$$aMoreno, L.A.$$uUniversidad de Zaragoza 000078196 700__ $$aDe Moraes, A.C.F. 000078196 700__ $$aCarvalho, H.B. 000078196 700__ $$aEstrada-Restrepo, A. 000078196 7102_ $$11006$$2255$$aUniversidad de Zaragoza$$bDpto.
