1. Wheeze is common among infants and toddlers;
recurrent wheeze may indicate underlying asthma.
2. A family history of asthma increases the risk of new onset wheeze.
3. Indoor exposure to formaldehyde is associated with the risk of new onset wheeze, with a 2% increase for each 10-unit increase in formaldehyde.
