OBJECTIVES: To describe the development of the medial longitudinal arch (MLA) ofthe foot of obese children and verify the concordance between 5 footprint indexes whichcharacterize such arch. METHODS: 156 obese children, both genders, between 4 and 10 yearsold, belonging to both public and private schools of the city of São Paulo, Brazil. The childrenwere classified as obese according to Cole et al (2000) and selected among 1535 studentsbetween 4 and 10 years old from 5 different schools. Afterwards, the footprints of each obesechild were collected and then the indexes that characterize the MLA were calculated: Cavanaghand Rodgers index - CR, Staheli index - IS1 and IS2, Chipaux-Smirak index - ICS, andfootprint angle - AA. RESULTS: CR, IS and ICS showed that a remarkable change in the MLAshape takes place in the transition from 8 to 9 years of age and the AA showed two transitionranges, from 6 to 7 and from 8 to 9 years of age. Generally speaking, the largest discrepancywas noticed in the IS1 classification when evaluating the MLA for those children and the CRone proved to be the most stable. CONCLUSION: It was observed that the MLA is formed later inobese children (8 to 9 years of age) comparing to non-obese children (5 to 6 years of age).Regarding the indexes, there was a similarity in the description of the MLA developmentbetween CR, ICS and AA. The IS needs more caution and its use should be restricted.
