The number of maternities by multiplicity of birth (singleton, twin, triplet and higher order) and the rate of multiple maternities were calculated by maternal age (5-year bands), deprivation decile and year of birth.
The increase in multiple maternities over time was strongly associated with changing patterns of maternal age (table 2).
Since the rate of multiple maternity increased with increasing maternal age (figure 1), this led to an increase in multiple maternities.
Our estimated total number of multiple maternities differed by only 1% from the published total number of multiple maternities in England for 1997 2001 6 (ONS), indicating any underestimation of multiple maternities was negligible.
Multiple maternities were significantly lower in the most deprived areas, and this was most evident in the older age groups.
Therefore, the number of multiple maternities (multiple pregnancies resulting in at least one registered live birth or stillbirth) had to be estimated.
The rate of multiple maternities, that is, the proportion of all maternities resulting in a multiple birth increased over the 12-year time period by 0.64% per year (95% CI (0.47% to 0.81%)) from 14.7/1000 maternities in 1997 to 15.6/1000 in 2008 (table 1).
By September, she had introduced a maternity collection through a deal with Destination Maternity, which expanded this spring.
Multiple maternity was also detected in over 30% of the clutches analyzed.
Our current orgy of multiple maternity does indeed leave little room for sexuality.
