366 MISUSE OF CHILD RESTRAINT SEATS IN MANITOBA: RESULTS OF A 2004 SURVEY.
Bibliographic record
Abstract
Introduction Child passenger restraints, including rear-facing infant seats, forward-facing toddler seats, and booster seats, provide protection for pediatric passengers traveling in motor vehicles. Objective To investigate the use and misuse rate of child restraint seats in Manitoba. Methods Characteristics of child restraint seat use were assessed at 10 child safety seat inspection surveys held between May 2004 and August 2004 in Manitoba. The sample of convenience included (1) rear-facing infant seat: for infants until they are at least 20 pounds and 1 year old (n = 49); (2) forward-facing toddler seat: for toddlers 20 to 40 pounds and 1 to 4 years old (n = 175); and (3) booster seats: for children 40 to 80 pounds and 4 to 8 years old (n = 118). In all, MCSC child safety seats specialists inspected a total of 342 child restraint seats. Results The overall rate of misuse was 63%, with 73% of infant carriers used inappropriately. The most common type of misuse found in infant carriers was loosely fitted seats (91%) followed by chest clips in the wrong position (86%). Seventy-four percent of forward-facing seats were incorrectly used. The most common type of misuse found in forward-facing child restraints was harness straps placed through the wrong slot (95%) followed by seats too loosely fitted (66%). Forty-three percent of booster seats were used incorrectly. The most common misuse found in booster seat was no head and neck protection offered (46%) followed by seat belts not crossing the child9s chest over the shoulder (37%). The risks of misuse of infant carriers compared with booster seats were nearly four times higher (odds ratio 3.63; confidence interval 1.75-7.55). The risks of misuse of forward-facing child restraint seats compared with booster seats were also nearly four times higher (odds ratio 3.68; confidence interval 2.24-6.04). Conclusions This paper is the first to describe child restraint seat misuse in Manitoba following the 1997 child restraint use survey conducted by Transport Canada. Infant carriers and forward-facing child restraint seats were much more likely to be misused than booster seats. This study also identified a statistically significant higher rate of infant carrier and forward-facing child restraint misuse compared with booster seat misuse in Manitoba. The Manitoba child restraint seat survey suggests that a large number of children still remain poorly protected when traveling in motor vehicles. The survey data presented here can be used to inform parents about the importance of correct child restraint use.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
