title: [Sociodemographic characteristics as risk factors for obesity and overweight in Spanish adult population].
abstract: OBJECTIVE
  To analyze the adult Spanish sociodemographic characteristics associated with a higher risk of excess weight and obesity. As a second aim, we analyze if there are gender differences regarding the development of overweight and obesity in different age groups.
  
  
  METHODS
  Transversal study of the National Health Survey of 2012. Body mass index was calculated and a number of sociodemographic variables were analyzed. An analysis of multinomial logistic regression was conducted.
  
  
  RESULTS
  In 2012 the prevalence of obesity in Spain was 18.5% for obesity and 39.0% for being overweight. The greatest risk of being overweight or obese versus being of normal weight corresponded to men, married, between 65 and 74 years old, in social classes where unskilled work is performed, in the autonomous city of Ceuta, and the autonomous communities of Extremadura and Andalucía, and in municipalities with fewer than 10,000 inhabitants. On the other hand, obesity risk is 2 times higher in men versus women between 25 and 64 years while overweight risk is higher in all age groups.
  
  
  CONCLUSIONS
  The sociodemographic characteristics associated with a higher risk of being overweight or obese in Spain have changed compared to those published previously. In the year 2012, obesity was more common in males, the maximum peak was between 65 and 74 years and the area with the highest prevalence of obesity was the autonomous city of Ceuta.
