Objective To describe the status quo and trends of food consumption of adult farmers at the age of 18-65 years from 9 provinces (autonomous regions) in China.
Methods The data of 8 rounds of follow-up visits of China Health and Nutrition Survey from 1991 to 2011 were used. The farmers aged 18-65 years were selected as study subjects by stratified multi-stage cluster random sampling method. Information on food intake and condiment intake was collected by 3-day 24-hour dietary recall and weight method. The changes of various food consumption were analyzed, and compared with the recommended intakes of the dietary pagoda for Chinese residents (2016).
Results In 2011, the farmers' average daily intakes of cereals and tubers, vegetables, fruits, meat, eggs, aquatic products, milk and dairy products, beans and nuts, edible oil, and salt were 555.7, 338.5, 80.4, 63.5, 28.5, 20.4, 2.3, 22.1, 40.5, and 10.0g, respectively. Compared with the data of 1991, the average daily intake of cereals and tubers, vegetables, salt, and salted vegetables decreased by 60.7, 26.5, 4.9, and 6.3 g, respectively, in 2011, showing a downward trend over time; the average daily intakes of flour and its products, fruits, meat, and edible oils increased by 29.1, 75.0, 17.5, and 8.4 g, respectively, in 2011, showing a upward trend over time. In 2011, the proportion of farmers whose intakes of cereals and tubers, vegetables, fruits, meat, aquatic products, and eggs met the recommended value of balance diet pagoda were 25.62%, 36.93%, 10.54%, 21.54%, 10.28%, and 11.78%, respectively.
Conclusion From 1991 to 2011, Chinese farmers' general dietary quality is improved, but their dietary pattern still deviates from the "balanced diet".
