title: [Red meat intake among employees of floating population aged 18-59 years old in China, 2012].
abstract: OBJECTIVE
  To evaluate the level of daily red meat intake and prevalence of excessive red meat intake among employees of floating population in China.
  
  
  METHODS
  48 511 employees of floating population aged 18 to 59 from 170 counties of 31 provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps (District) were selected by stratified cluster sampling method. Information on red meat intake was collected by semi-quantitative food frequency questionnaire. Average intake of 100 g/day, recommended by the World Cancer Research Fund, was used as the cut-off point to estimate the prevalence of excessive red meat intake. After performing the complex weighted analysis, level of daily red meat intake and prevalence of excessive red meat intake were calculated by demographic characteristics including age, education, industries and body mass index etc.
  
  
  RESULTS
  1)The mean daily red meat intake was 125.9 g (95%CI: 116.5 g-132.5 g), higher in men (141.6 g, 95%CI:131.3 g-148.9 g)than in women (104.7 g, 95%CI: 95.8 g-111.2 g) (P < 0.01). Results from the Tendency Test did not show statistically significant changes on the red meat intake related to age, education level or body mass index (P values for trend were all greater than 0.05). The standardized mean daily intake of red meat, adjusted by 2010 census data of China, was 121.0 g (95% CI:113.4 g-128.7 g). 2) The prevalence of excessive red meat intake was 36.2% (95% CI:33.0%-39.3%) significantly higher in males (42.4% , 95% CI:38.9%-45.8%) than in females (27.8%, 95%CI:27.1%-31.0%) (P < 0.01). The prevalence was estimated to be the highest among the population aged 30-39, with 43.5% (95%CI:39.7%-47.4%) in males and 30.1% (95%CI:26.5%-33.9%)in females. The standardized prevalence, adjusted by 2010 census data of China, appeared to be 34.6% (95%CI:31.9%-38.0%).
  
  
  CONCLUSIONS
  The level of daily red meat intake was higher than 100 g/d, the standard recommended by the World Cancer Foundation, among floating population of China. Both the mean daily red meat intake and prevalence of excessive red meat intake were higher in floating population than that in the local residents in China.
