They use the term 'peak height velocity' and this is found to peak at age 12 for girls and 14 for boys. It is probably something to look out for in the next few waves. <br /><br />Behrman and Rosenweig 2004 points out that birthweight divided by gestation rather than birthweight is a better measure of the healthiness of a child which might be worth a try as an independent variable.Jason Loughreynoreply@blogger.comtag:blogger.com,1999:blog-38545607.post-39280603883043055412010-12-14T20:43:20.558+00:002010-12-14T20:43:20.558+00:00Well Liam there is a bit of variation:using mother...Well Liam there is a bit of variation:using mother's education going from bottom (mother with lower secondary education or less) to mother being a graduate is "worth" about 1.5cm.Kevin Dennyhttps://www.blogger.com/profile/17891633553910348880noreply@blogger.comtag:blogger.com,1999:blog-38545607.post-84965360923867264472010-12-14T16:36:45.766+00:002010-12-14T16:36:45.766+00:00These are interesting results.

One interpretation is that there is not a sufficient variation in SES-related factors that would influence stature among this generation of Irish children.Liam Delaneyhttps://www.blogger.com/profile/04905424104233324535noreply@blogger.comtag:blogger.com,1999:blog-38545607.post-27149486420393914792010-12-14T01:01:25.957+00:002010-12-14T01:01:25.957+00:00Ok..the height effect seems to be:
an extra cm is ...Ok..the height effect seems to be:<br />an extra cm is worth 0.375 of a point up to about 1.36m and nothing thereafter.<br />An extra kilogram in birth weight is worth about 2.748 points up to about 3.6kg and is slightly negative thereafter.<br />SES is a set of dummies, medical card status, sex, household income in there too.<br />Of course there are just rough estimates with limited controls, no school stuff for example.<br />But being small does hurt it seems.Kevin Dennyhttps://www.blogger.com/profile/17891633553910348880noreply@blogger.comtag:blogger.com,1999:blog-38545607.post-5732219725139383782010-12-13T21:56:32.342+00:002010-12-13T21:56:32.342+00:00Kevin,
