Nutrient intake and food selectivity in children with Tourette syndrome.

Objectives

Children with Tourette syndrome (TS) have been shown to exhibit high levels of food selectivity; however, its association with nutritional status has yet to be explored. The current study explored macro and micronutrient intake and food selectivity among children with and without TS, using 24-hour dietary recall and the Child Eating Behaviour Questionnaire.Method: Parents of 43 children diagnosed with TS and 38 age-matched children without a clinical diagnosis completed an online 24-hour food diary.

Results

Fifty-eight per cent of children with TS were identified as falling outside of the healthy BMI range (underweight = 24.2%; overweight = 27.3%; obese = 6.1%). Children with TS also consumed fewer portions of fruit and vegetables along with meeting the daily reference nutrient intake guidelines significantly less often for vitamins B3, B6 and C, selenium and phosphorus compared to children without TS.

Conclusions

Understanding the nutritional risk of children with TS relative to other children is important to clinicians and health care professionals who oversee nutritional inspection in primary care, and caregivers who are worried about the impact of limited or restricted diets.
