Effect of minimal acupuncture for infantile colic: a multicentre, three-armed, single-blind, randomised controlled trial (ACU-COL).

BACKGROUND: Evidence for treating infantile colic with acupuncture is contradictory.

AIM: To evaluate and compare the effect of two types of acupuncture versus no acupuncture in infants with colic in public child health centres (CHCs).

METHODS: A multicentre, randomised controlled, single-blind, three-armed trial (ACU-COL) comparing two styles of acupuncture with no acupuncture, as an adjunct to standard care, was conducted. Among 426 infants whose parents sought help for colic and registered their child's fussing/crying in a diary, 157 fulfilled the criteria for colic and 147 started the intervention. All infants received usual care plus four extra visits to CHCs with advice/support (twice a week for 2 weeks), comprising gold standard care. The infants were randomly allocated to three groups: (A) standardised minimal acupuncture at LI4; (B) semi-standardised individual acupuncture inspired by Traditional Chinese Medicine; and (C) no acupuncture. The CHC nurses and parents were blinded. Acupuncture was given by nurses with extensive experience of acupuncture.

RESULTS: The effect of the two types of acupuncture was similar and both were superior to gold standard care alone. Relative to baseline, there was a greater relative reduction in time spent crying and colicky crying by the second intervention week (p=0.050) and follow-up period (p=0.031), respectively, in infants receiving either type of acupuncture. More infants receiving acupuncture cried <3 hours/day, and thereby no longer fulfilled criteria for colic, in the first (p=0.040) and second (p=0.006) intervention weeks. No serious adverse events were reported.

CONCLUSIONS: Acupuncture appears to reduce crying in infants with colic safely.
