In terms of the distribution of other covariates given in
Table 1, about 44% of the children included in the analysis
here were born to mothers aged over 25 years. Over one
half of all births were to women aged less than 25 years. In
fact, one in four births was to teenage mothers (aged under
20; see Table 1). This assumes importance given the evidence
that young age at childbearing, particularly in
adolescence, is associated with an increased risk of having
low birth weight children. Just over one-quarter of the
births were of first order, and a similar number were of
second order, and the rest were of higher order births.
There is a also strong correlation between birth order and
age. While two-thirds of births to teenage mothers were
of first order, it was only one-third among those aged
20–24 years. The other proximate variables that are likely
to be significant in determining low birth weight are source
