Dietary diversity scores were assessed based on frequency of consumption of individual food items categorized into 11 individual food groups.

Results: Overweight children showed the highest mean score for cereals (F=2.209, P=0.005), vegetables (F=5.234, P=0.001), non-vegetarian foods (F=12.3920, P=0.000), mixed dishes (F=9.899, P=0.000), beverages (F=9.654, P=0.000), sweets and sugar (F=5.122, P=0.002) and fats (F=10.263, P=0.000). Mean scores for vegetables, sweets, beverages and fat consumption increased with increasing weight. High scores for pulses and legumes consumption was observed in obese children.
