closeMaternal recall bias

This effect is modest (OR 3.04 versus 2.44), but statistically significant. This demonstrates that non-genetic in utero and/or post-natal factors may play a significant role in the transmission of asthma susceptibility.

Looks pretty much like a maternal recall bias - explained in more detail at http://www.wjst.de/blog/2010/04/25/clearly-biased-maternal-recall-of-asthma-in-the-family/

It could also be that mothers to appear more acceptable to the interviewer more often reported paternal asthma than maternal asthma when their children suffered from asthma. This then could lead to an underestimation of the "maternal effect".
