Descriptive correlational study. The objectives were the following: 1) evaluate maternal perception of her child’s weight through two test, Word-perception (WP) test and the Body mass index (BMI) of the child as perceived by the mother (Body weight index perception [BWIP]); 2) evaluate the sensitivity and specificity of the tests, and 3) quantify BMI heritability (h2) in 173 mother-child dyads. WP was assessed by asking the question, How do you think your child is? For assessing BWIP, the mother referred the child’s weight and height, and we calculated the child’s BMI as perceived by the mother. The weight and height of the mothers and their children were measured. We found that 10.3% of mothers of children with Overweight (OW) and 1.8% of mothers of children with Obesity (OB) perceived their children adequately by means of WP; by means of the BWIP test, 38.5 and 67.3% of mothers of children with OW and OB, respectively, exhibited adequate perception. BWIP sensitivity was 55.3% and specificity was 54.4%. BWI h2 was 15%. We was concluded that mothers did not perceive the OW-OB of their children, and that asking the mother for the weight and height of the child (BMIP) will aids her to perceive the OW-OB of her child. The BWI h2 indicate that the lifestyle factors of this population contribute to OW-OB. Given the broad socioeconomic and cultural diversity, these results of the southeastern Mexican state of Campeche should be evaluated with similar study designs.
