CONCLUSIONS
In this study, we found that the
childhood asthma risk increased by
the number of family members affected by
asthma. A family history of a
grandparent with asthma was associated with childhood asthma and the
association was only partially mediated by parent with asthma. In
addition, children who had father
and parental grandfather with asthma had similar magnitude of asthma
risk with those who have both parents with asthma. Our findings could be
used to identify children at high risk for asthma in early childhood.
