The impact of sleep duration on self-rated health.
OBJECTIVE
To review the association between sleep duration and self-rated health.


METHODS
A search for original and review articles focusing on sleep duration and self-rated health was performed in PubMed. The general search strategy was [("sleep duration" OR "total sleep time" OR "time in bed") AND "self-rated health"].


RESULTS
We found 22 articles in the English language; 8 articles with no direct association between sleep duration and self-rated health were excluded. Of these articles, 14 were considered potentially relevant and examined in detail, and 9 were excluded for not having self-rated health as the primary outcome. This work was compounded by 5 papers. The extremes of sleep duration (short or long) exhibited an interaction with poor or worse self-rated health.


CONCLUSIONS
The sleep duration issue should be considered when inquiring about health conditions, as this factor can lead to adverse results in global health status.
