Children belonging to the rural, middle income urban and affluent urban group were assigned an
urbanisation rank 1, 2 and 3 respectively. Total frequency of consuming items from any food category
was computed for each child. Correlation between urbanisation rank and frequency of food
consumption was studied to see the impact of urbanisation on food consumption. The nutrient intake of
children was calculated separately for each of the three record-keeping days. In order to get a balanced
representation of weekdays and week ends, mean intake of two week days was multiplied by six and
added to intake on week ends; the resulting figure was divided by seven to get mean daily intake for
each individual representing the whole week.
