Table 6. Mean Dietary Variety Score and mean Diet Diversity Score by meal preparation location and age group.

¹⁾The study subjects were divided into two groups according to the location where meals are prepared for a single day: 1) home-made meal group (HMG) (≥ 2 meals prepared at home consumed), 2) non-home-made meal group (NHMG) (≥ 2 meals prepared away from home consumed).

²⁾DVS = Dietary Variety Score; counts the total number of different food groups consumed in a single day from 17 food groups (i.e., cereals, potato and starches, sugars and sweeteners, pulses, nuts and seeds, vegetables, fungi and mushrooms, fruits, meats, eggs, fish and shellfishes, seaweeds, milks, oils and fat, beverages, seasoning, and others).

³⁾DDS = Diet Diversity Score; counts the total number of foods consumed in a single day from five major food groups (i.e., cereals-grains, meats, fruits, vegetables, and dairy products).

⁴⁾Data values are reported as mean ± SE.

⁵⁾P-value was obtained from the t-test for continuous variables (^* P < 0.05, ^** P < 0.01).
