OBJECTIVES: To assess the concordance between corporal self-perception and BMI calculated in a population of volunteers. SECONDARY OBJECTIVES: to know the percentage of @entity2973 , normoweight and @entity28 individuals in this population. SUBJECTS: The study includes 160 volunteers recruited at the G  mez Ulla and Severo Ochoa Hospitals in Madrid during the 4th edition of the "Obesity Day". ACTIONS: A total of 160 interviews were carried out, comprising a first group of 10 questions about how @entity28 is understood, how they classify themselves by self-perception ( @entity28 , @entity2973 or normoweight individuals), the incidence of @entity28 in the family, living habits and the number of previous failed attempts to lose weight. In the case of a positive response to the last question, the survey is extended to 19 questions, analyzing the reasons, prescriptors, methods used, and @entity353 results obtained. RESULTS: The mean Body Mass Index (BMI) of the interviewees was 26.2 +/- 4.97 kg/m2, with 27.45 +/- 5.4 kg/m2 for males and 25.76 +/- 4.7 kg/m2 for @entity1 . Overweight @entity1 represented 32.5%, with 27.3% @entity2973 @entity1 , while @entity28 @entity1 accounted for 25.6% and @entity28 @entity1 amounted to 20.6%. The differences were not significant between sexes, normoweight, @entity2973 and @entity28 groups. The concordance between self-perception and BMI using the kappa index was 0,464 for the total sample, 0.229 for males and 0.527 for @entity1 , and according to the valuation scale proposed by Landis and Koch, it would correspond to a moderate degree of agreement for the population in general, medium for @entity1 and moderate for @entity1 . CONCLUSIONS: Overweight and @entity28 affect a high percentage of the Spanish population (almost 50%). @entity1 show greater concern about being @entity2973 , are more likely to participate in prevention campaigns, and present a corporal perception more in line with their true weight. Preventive campaigns should be implemented to reach the male population better, taking into account that this population presents a greater cardiovascular risk. It is important to place the problem of @entity28 in the right terms, without any "obesophobia" leading to disorders of the eating behaviour, while indicating the importance of the risk attributable to @entity28 and excess weight.
