Objective: To compare the prevalence of misperception between 2 groups of mothers towards their children's weight status from an indigenous population in San Antonio de los Cobres (SAC) and a Buenos Aires (BA) mixed population.
Methods: Questionnaires regarding mothers' perceptions about their children's shape were performed during 2014.
Results: Overall, 152 SAC children (80 males) aged 9.0+2.1 years and 119 BA children (59 males) aged 8.1+1.7 years were evaluated. There was a significant difference in the prevalence of maternal misperception of normal weight vs overweight children in both ethnicities: SAC (38.8% vs 66.7%) and BA (33.3% vs 62.9%).
Conclusion: These results suggest that maternal misperception of children's overweight was poor in both communities despite having different socio-economic and ethnic backgrounds.
