Sleep-wake behaviour during the first 12 months of life and associated factors: a systematic review

This paper aims to provide a systematic review of the literature on the
associated factors with infant sleep-wake behaviour during the first 12
months of life, namely (1) the factors positively and negatively
associated with sleep-wake behaviour and (2) the factors positively and
negatively affected by sleep-wake behaviour. This systematic review was
based on a standard protocol constructed according with the Preferred
Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)
statement and included 146 papers. Two typologies of factors were
found in the literature: factors positively and negatively associated with
infant sleep-wake behaviour and effects of sleep-wake behaviour.
Different factors were identified as being positively and negatively
associated with the different sleep-wake behaviours and positively and
negatively affected by the different sleep-wake behaviours during the
first 12 months of life. Some inconsistent results could be explained by
methodological differences between the studies.
