title: [Changes of dietary pattern among adults in Liaoning province, 1989 to 2006].
abstract: OBJECTIVE
  To study the changes of dietary pattern among adult residents in different areas of Liaoning province from 1989 to 2006.
  
  
  METHODS
  Healthy adults (6213 subjects) at age of 18 - 65 years from 480 households in three cities (Shenyang, Yingkou, Wafangdian) and three counties (Qingyuan, Huanren, Chaoyang) were selected with stratified multiple cluster random sampling. The information on nutrient intake of the subjects were collected from datasets of Chinese Health and Nutrition Survey conducted in 1989, 1991, 1993, 2000, 2004, and 2006. Different food intake, the nutrients intake percentages for recommended nutrition intake (RNI) and appropriate intake (AI), and the percentages of total energy and protein from grain, animal product, bean and its product were calculated to assess the residents' dietary pattern and nutrition status. The changes of dietary pattern among adult residents were analyzed.
  
  
  RESULTS
  Among the residents, there were a 38.1% of decreased intake for grain (from 601.9 to 372.5 g/d), 20.5% for potato (from 75.6 to 60.1 g/d), 25.1% for beans (from 38.7 to 29.0 g/d), and a 77.2% of increased intake for fish and shrimp (from 25.0 to 44.3 g/d), 36.9% for livestock and poultry (from 65.6 to 89.8 g/d), 47.7% for fruit (from 70.7 to 104.4 g/d), and intake of milk product (from 5.8 to 21.3 g/d), egg (from 17.3 to 35.7 g/d), vegetable (from 296.1 to 316.3 g/d) were also increased from 1989 to 2006. During the period, the intake percentages of energy and protein from grain decreased from 67.5% (8.7 MJ/12.8 MJ per day) to 51.5% (5.0 MJ/9.6 MJ per day) and from 72.0% (66.2 g/91.9 g per day) to 59.7% (45.3 g/75.9 g per day), and on the contrary those from animal products increased from 8.9% (1.1 MJ/12.8 MJ per day) to 14.8 (1.4 MJ/9.6 MJ per day) and from 15.9% (14.6 g/91.9 g per day) to 27.9% (21.2 g/75.9 g per day), respectively. In 2006, the intake of vitamin A (508.9 µg/d) was 67.6% of it's RNI, intake of vitamin B(2) (0.9 mg/d) was 64.6% and the intake of calcium (453.7 mg/d) was 52.5% of it's AI among the residents.
  
  
  CONCLUSIONS
  The intake of plant food decreased and that of animal food increased from 1989 to 2006 and the dietary intakes of calcium, vitamin A, vitamin B(2) need to be increased among adult population of Liaoning province.
