Kangaroo mother care and infant biopsychosocial outcomes in the first year: A meta-analysis
Section snippets
Search strategy
Searches were conducted in MEDLINE, Embase, PsycINFO, Cinahl and AMED (from database inception to October 2015) by a health sciences librarian. Both database specific subject headings and text word fields were searched for the concepts “kangaroo care” and “infants”. Synonymous terms were first combined with the Boolean “OR”. These two concepts were then combined with the Boolean “AND”. In all databases, truncation symbols and adjacency operators were used in text word searches when appropriate,
Results
The search strategy yielded 3177 (out of which, 479 were marked as duplicates) studies. Out of those, 413 articles were assessed for eligibility, and among these, 13 were included in the meta-analysis. See Fig. 1 for a flow chart of study screening. The number of outcomes among the 13 studies was as follows: cognitive (n = 9), motor (n = 8), self-regulation (n = 4), socio-emotional (n = 4) and temperament (n = 5). We tested whether study design (i.e. observation versus RCT) affected the
Summary of the evidence
Through a systematic review of the literature, we report results of the first meta-analysis examining the effects of KMC on biopsychosocial outcomes in the first year. KMC is targeted to a preterm population. Infants exposed to KMC show significantly better emotion regulation than infants exposed to usual care. No effects were found in any other parameters examined. However, exploring the role of potential moderators, duration of KMC was associated with cognitive and motor development, and
