To examine the relationship between chewing performance and dietary intakes in children with Cerebral Palsy (CP). Forty children with CP aged between 2 and 6 years were included. The Karaduman Chewing Performance Scale (KCPS) and the Mastication Observation and Evaluation (T-MOE) instruments were used to evaluate chewing performance. Daily dietary intakes were measured from a 24-h food record with digital photographs including the amount and textures of all foods consumed during the meal. Chewing function was impaired in 70% of children. There was a negative low-to-moderate correlation between KCPS scores and daily protein intake (r = −0.32, p = 0.04), but not with energy and other macronutrients. The percentage of daily dietary intakes from ‘liquid-blenderized’ foods were positively correlated with KCPS, and negatively correlated with T-MOE scores (p < 0.001). There was a significant negative association between the percentage of daily dietary intakes from ‘easy to chew & regular solid’ foods and KCPS scores, and a significant positive association was found with T-MOE scores. In conclusion, the amount of daily protein intake decreased, and daily intake ratios of energy and macronutrients from liquid-blenderized foods increased as chewing performance decreased in children with CP. Timely diagnosis and treatment of chewing dysfunction can serve as a useful treatment option to ensure adequate dietary intake in children with CP, and also to decrease the burden of their parents and improve their quality of life.
