Infant massage may ease crying, sleep problems
NEW YORK (Reuters Health) - Just like their stressed-out parents, babies may take comfort from a gentle massage, a research review suggests.
Infant massage has long been used in many Asian and African cultures to ease babies' colic and fussiness, help them sleep, and even aid their growth and development. There is growing interest in infant massage among parents in Western countries as well.
To assess the science behind the practice, UK researchers analyzed 23 clinical trials in which infants younger than 6 months were randomly assigned to receive massage or not.
They found that across nine of the studies, gentle massage appeared to improve infants' sleep patterns, ease crying, and strengthen mother-child bonding. Some studies found that massage lowered babies' levels of certain stress hormones.
Given this apparent hormonal effect, it's "not surprising" that massage seemed to improve sleep and crying, according to the researchers, led by Angela Underdown of the University of Warwick in Coventry, England.
On the other hand, the nine studies showed no benefits for infants' growth and development. And the researchers considered the rest of the 23 trials to have a "high risk of bias" because of concerns about their methodology; some reports, for instance, lacked information about how the study was designed and conducted.
Overall, the results offer "tentative support" for teaching parents and caregivers infant massage -- though there's not enough evidence to universally recommend the practice, the investigators note in the latest issue of The Cochrane Library, a publication of the Cochrane Collaboration, an international organization that evaluates medical research.
The trials included in the review were conducted in China, North America, Great Britain and Israel, and included 598 healthy, full-term infants. In some studies, researchers provided the massage, while parents did in others. Most looked at the effects of daily massage over a period of weeks.
It's not clear how often, when or for how long babies should receive massage to get the most benefits. Underdown and her colleagues recommend that future studies examine these questions.
