Abstract
China has been undergoing a dramatic transition in food consumption since a few decades ago. The composition of diet has changed significantly. We assessed the trend of dietary diversity in China with four indicators. Count Index (Count), Dietary Diversity Score (DDS), Entropy (Entropy) and Simpson Index (Simpson) were adopted to measure the dietary diversity of 24542 adults (>17 years) through the data of 4 rounds (2004, 2006, 2009, 2011) of China Health and Nutrition Survey (CHNS). Results indicated that dietary diversity increased over time, and it was unequally distributed among different regions and families. Further investigation found that it was positively associated with accessibility of food (p<0.01) and other social-economic factors such as family income, household size, gender, age, education and region.
