The aim of this randomized, controlled trial was to test whether sweet taste and chewing modify self-report of pain intensity and negative affect caused by blood-draws and vaccination in children. Subjects were recruited (age mean +/- SD; 9.82 +/- 0.8 years) from schools (n = 115) and a hospital (n = 101). Subjects were assigned to Control, Sweet, Chew or Sweet+chew interventions. Pain intensity was rated on the Coloured Analogue Scale (CAS) and affective quality on the Faces Pain Scale (FPS). / In school and hospital settings a Sex by Sweet by Chew interaction was seen on CAS (p = 0.29; p < 0.01) and FPS (p < 0.05; p < 0.05) respectively. A consistent pattern was seen in which chewing reduced and sweet taste increased pain ratings in boys. The opposite effect was seen in girls. When sex was not considered no significant differences between groups were seen. / Sweet taste and chewing appear not to have useful analgesic effects. Sex must be considered in future investigations.
