Background: The purpose of this study is to determine the association between dietary diversity and weight status of aboriginal primary school children. Methods: Dietary diversity measures food intake diversity in food groups, whereas weight status indicates nutritional status. Dietary serving score (DSS) method was used to determine dietary diversity status, while weight status was assessed using BMI-for-Age (BAZ). Results: Results reported that 51.9% and 54.2% were male and 10 years old-12 years old children, respectively. A total of 36.4% of children consumed cereal/grains diversely while fruits were not diversely consumed by 96.4% of them. Approximately 60.8% of children were reported to have normal weight status, which was followed by overweight (17.7%), obese (16.7%) and thinness to severe-thinness (4.8%). There was an association between DSS of fruits, meat/fish/ eggs, legumes/lentils and milk/dairy products with age group, vegetables DSS with gender and BAZ with parental employment status (P < 0.05). The association between DSS of all food groups and total with BAZ were reported to be insignificant, indicating no association between both variables (0.00 < r < 0.30; P > 0.05). Conclusion: Children from this study were shown to practice a monotonous diet, although the majority of them were within normal weight status.
