Measurement models of the latent construct of three dietary patterns among adults from Jiangsu Province, China in 2007–2014 (a men and b women). In model of men: RMSEA = 0.063, GFI = 0.946, CFI = 0.763, ACFI = 0.923 and PGFI = 0.667. In model of women: RMSEA = 0.047, GFI = 0.960, CFI = 0.862, ACFI = 0.946 and PGFI = 0.706. Rectangles indicate observed variables, and oval is latent variable in the model. All factor loadings and regression coefficients in the figure are significant (P < 0.05)
