Furthermore, mean birth weight was lower in newborns of adolescent than of adult mothers for each completed week of gestation (Figure 1).
Finally, a comparative graphical analysis of birth weight for each completed week of gestation was performed in the subset of term-newborns to appreciate potential differences of growth retardation in adolescent and adult mothers over time.
For each completed week of gestation, we divided the total number of births into 100 equally sized groups, each representing an increment of 1 percentile point.
We requested data on the number of live births at or after 22 weeks for each completed week of gestation by multiplicity and mode of delivery for several years of which the most recent was 2008.
For all births, Table 2 shows the birth weight delineating the top of each percentile step from 1 through 99percentt, for each completed week of gestation (see additional file,worksheet 'Table 2-All').
In this paper, we have used 1999 and 2000 United States nationwide Natality databases to generate multiple reference percentiles for birth weight at each completed week of gestation.
An array of living and preserved organisms (Table 1) was scattered throughout the lab at different workstations (see Online Supplemental Materials for the complete week one lesson plan in Appendix 2).
A pack of buffer accumulators of 500 A h is necessary for a complete week without solar panel charging in case of very cloudy weather as might occur during the cyclonic period.
Additionally, POBWs for 3rd, 10th and 90th percentile birth weight were estimated within each completed gestational week for sub-samples of parity and maternal height, to ensure that the model adjusted appropriately for these non-pathological determinants.
