Food selectivity and autism: A systematic review

Table 2 Characteristics of included studies - sensory processing

Study	Number and age	Objective	Measures	Specific findings
1	Children with ASD (n = 53); children without ASD (n = 58)	Assessing the relationship between oral sensory processing and food selectivity in children with ASD	Food frequency questionnaire; the vineland adaptive behaviour scales; differential abilities scale; sensory profile (questionnaire); the subscale: Oral sensory over-sensitivity	Children with ASD had more atypical sensory processing than children without ASD and refused more food than those with typical oral sensory sensitivity
2	65 children with ASD and 30 with typical development	Analysing dietary intake, nutritional status and sensory profile in children with and without ASD	The SAYCARE study food frequency questionnaire; the Spanish version of the Short Sensory Profile; for anthropometric measurements of weight and height: Standardised by Frisancho and the World Health Organisation	Children with ASD had a higher sensory sensitivity, a lower intake of dairy products and a higher intake of cereal and protein foods than children with typical sensory performance with ASD
