Long‐term Dietary patterns in China, 1991–2009

Little is known about dietary patterns over time in transitional societies. Using the China Health and Nutrition Survey, we followed 3012 adults aged 18 y or older in 1991 with complete dietary data in each of 7 waves (1991, 1993, 1997, 2000, 2004, 2006 and 2009). Diet was measured by a combination of a household food inventory (detailed weighing of changes in household food) and 3 consecutive days of 24‐h recall. Dietary intake was grouped into 42 food groups. A factor analysis (STATA 12), followed by a varimax orthogonal rotation was performed at each wave. Factors with eigenvalues >1 were retained.
