Community primary care pediatric offices.
Children younger than 36 months attending well-child care visits.
Prospective data collection of demographics, developmental stage, and presence and location of bruises.

A X2 test or Fisher exact test was used to determine the significance of differences.
Presence and location of bruises as related to age and developmental stage.
Bruises were found in 203 (20.9%) of 973 children who had no known medical cause for bruising and in whom abuse was not suspected.
Only 2 (0.6%) of 366 children who were younger than 6 months and 8 (1.7%) of 473 children younger than 9 months had any bruises.
Bruises were noted in only 11 (2.2%) of 511 children who were not yet walking with support (cruising).
However, 17.8% of cruisers and 51.9% of walkers had bruises (P<. 001).
Mean bruise frequency ranged from 1.3 bruises per injured child among precruisers (range, 1-2 bruises) to 2.4 per injured child among walkers (range, 1-11).
The most frequent site of bruises was over the anterior tibia and knee. (...)
