title: [Perception of physical fitness is associated with perception of body weight; sociodemographic analysis in Spain].
abstract: BACKGROUND
  The objective of this study was to analyse the relationship between sociodemographic characteristics, body weight perception and physical fitness perception.
  
  
  METHODS
  Survey by means of personal interview. The sample consisted of 8,594 participants living in Spain between 15 and 97 years of age. Sampling error was ± 1.07%.
  
  
  RESULTS
  Of the people who reported having good or excellent physical fitness, there was a proportionally greater prevalence of males, people aged 15 to 34, people with university studies and people from an upper or very upper social class (P < 0.001). It was also inferred that there was a greater possibility of perceiving deficient or very bad physical fitness in cohorts who felt that they should gain a bit of weight (OR = 2.87), lose a bit of weight (OR = 2.31) or lose a lot of weight (OR = 8.78).
  
  
  CONCLUSIONS
  Perception of physical fitness is associated with perception of body weight, independently of people's sociodemographic characteristics.
