Swartz A, et al. - In this meta-analysis, researchers intended to determine if there is an association between early child care attendance and the risk of childhood asthma and wheezing. In MEDLINE, CINAL, and EMBASE, peer reviewed studies published from 1964–January 2017 were identified using MeSH headings relevant to child care and asthma. Investigators found that early child care attendance increases the risk of wheezing among children 2 years of age or younger, but does not increase the risk of wheezing among children over 2 years of age. In children 6 years of age or older, early child care attendance was not significantly related to the risk of asthma or wheeze.
