- Values are shown as the median (M) and quartile ranges (Q). The differences of the amounts of food intake were compared using the method of Kruskal–Wallis H test among the three groups, both in males and females
- The amounts of food intake, staple food, dishes, porridge did not differ significantly among the three groups (χ2 = 3.223, P = 0.200; χ2 = 5.319, P = 0.070; χ2 = 4.540, P = 0.103; χ2 = 4.030, P = 0.133), while, the intakes of soup were significantly (χ2 = 10.891, P = 0.004). When compared the three groups with each other, the intake of soup was higher in OH group than MH group and HH group (χ2 = 22.915, P = 0.012; χ2 = 28.406, P = 0.023), and no significant differences were found in the intake of soup between MH group and HH group (χ2 = 5.492, P = 1.000). There were no significant differences were found in the amounts of food intake, staple food, dishes, porridge and soup among the three groups in males (χ2 = 0.877, P = 0.645; χ2 = 1.688, P = 0.430; χ2 = 2.658, P = 0.265; χ2 = 1.311, P = 0.519; χ2 = 3.976, P = 0.137). There were no significant differences were found in the amounts of staple food, dishes and soup among the three groups in females (χ2 = 2.727, P = 0.256; χ2 = 4.332, P = 0.115; χ2 = 0.722, P = 0.697). The amounts of the food intake and porridge were significantly different among the three groups in females (χ2 = 9.219, P = 0.010; χ2 = 9.677, P = 0.008). In the amounts of the intake of food, the intake of OH group was higher than that of HH group (χ2 = 6.701, P = 0.029); MH group was higher than that of HH group (χ2 = 6.708, P = 0.029), and no significant differences were found between OH and MH groups (χ2 = 0.787, P = 1.000). In the intake of porridge, OH group was higher than that of MH group (χ2 = 6.701, P = 0.029), but with no significant differences with MH group (χ2 = 3.528, P = 0.181); MH group did not differ significantly with HH group (χ2 = 1.117, P = 0.872)
