title: Doubling over ten years of central obesity in Hong Kong Chinese working men.
abstract: BACKGROUND
  Obesity is now an epidemic in most parts of the world. In this cross sectional study, we report the most recent data on obesity in Hong Kong Chinese working population and compare the changes over 10 years.
  
  
  METHODS
  Between July 2000 and March 2002, 5882 adult subjects from the working class in Hong Kong were recruited (2716 men (46.2%) and 3166 women (53.8%)). They were randomly selected using computer generated codes according to the distribution of occupational groups. Results of this study were compared with the data collected from a prevalence survey for cardiovascular risk factors in a Hong Kong Chinese working population conducted in 1990 (1513 subjects, 910 men (60.1%) and 603 women (39.9%)).
  
  
  RESULTS
  Standardized percentages of overweight, obesity, and central obesity, in Hong Kong Chinese working population were 59.7%, 35.0%, 26.7% in men and 32.0%, 21.7%, 26.7% in women. Compared to the data collected in 1990, the percentage of obesity increased by 5% in men and reduced by 6% in women. The percentage of central obesity doubled in men (from 12.2% to 26.7%) but remained stable in women.
  
  
  CONCLUSIONS
  There is a doubling of the percentage of central obesity in Hong Kong Chinese working men over previous decade. Education and proper lifestyle modification program to tackle this social health issue are urgently indicated.
