title: [Survey of dietary intake of Chinese adults in 2010].
abstract: OBJECTIVE
  To analyze the status of dietary intake of Chinese adults in 2010.
  
  
  METHODS
  In 2010, China Chronic Disease Surveillance was carried out in 31 provinces and Xinjiang Production and Construction Corps. The survey was undertaken in 162 surveillance sites in the national disease surveillance points system by stratified multi-stage cluster random sampling. The participants were local residents (living in the area for more than 6 months) aged 18 years and above in the surveillance sites. A semi-quantitative food frequency questionnaire was used to measure the dietary intake for 97 187 urban and rural adults aged 18 years and above. After complex weighting for the sample, the average daily consumption for major food was analyzed for different genders and regions.
  
  
  RESULTS
  After complex weighting, the median of cereal, rice and wheat flour intake for Chinese adults was 375.0 g. The median of livestock meat intake was 57.1 g with western areas (85.7 g) much higher than eastern (57.1 g) and central areas (46.2 g) (χ² = 2054.82, P < 0.01). The median of poultry intake was 7.1 g, eastern areas (10.0 g) higher than western and central areas (both 6.7 g) (χ² = 1210.86, P < 0.01). The median of seafood intake was 14.3 g, eastern (15.0 g) much higher than central (14.3 g) and western areas (7.1 g) (χ² = 5603.37, P < 0.01). The median of daily intake for eggs was 21.4 g, western (14.3 g) lower than eastern and central areas (both 21.4 g) (χ² = 1699.11, P < 0.01). The median of dairy product intake was 42.9 g, eastern (57.1 g) higher than western and central areas (both 35.7 g) (χ² = 196.35, P < 0.01). Overall, 52.8% of urban and rural residents did not meet recommended amount of fruit and vegetable intake. The rate of inadequate intake of fruit and vegetable was higher in rural (55.7%) than urban areas (46.1%, χ² = 929.43, P < 0.01).
  
  
  CONCLUSIONS
  The adult intake of cereal category foods tended to decline in 2010, and the intakes of vegetable and fruits, fishery products as well as dairy products were evidently deficient and regionally varied.
