title: Burden of overweight in Germany: prevalence differences between former East and West German children.
abstract: BACKGROUND
  Given the increasing prevalence of childhood overweight, we aimed to quantify the population burden and evaluate potential regional differences in anthropometric characteristics and prevalence of overweight in fourth graders in two German cities.
  
  
  METHODS
  Data were analysed from a cross-sectional school-based study conducted in 1995-96 in Dresden (former East Germany) and Munich (former West Germany) as part of the International Study of Asthma and Allergies in Childhood. Height and weight of the children were measured, and the parents completed a questionnaire. 2474 children age 9-10 years provided anthropometric data. Overweight was defined based on the age-specific and gender-specific international cut-off values for body mass index.
  
  
  RESULTS
  Dresden children were on average 1.2 kg lighter and >1 cm taller than their Munich peers. The prevalence of overweight in Dresden was 15.2% in girls and 14.2% in boys compared with 24 and 22.2%, respectively, in Munich. Differences were observed between Dresden and Munich with respect to the proportion of children of non-German nationality, household smoking, breastfeeding practices, and individual dietary behaviours. Even in combination these factors were not able to explain entirely the between-city overweight differences.
  
  
  CONCLUSIONS
  A substantial proportion of pre-adolescent children in Germany is now considered overweight with marked regional differences in prevalence. Comparison of population-level factors indicate that other unmeasured determinants of overweight may be responsible for the marked differences in the prevalence of overweight.
