The most frequent mechanisms of injury were falls (n=67\u2009599, 85.2%), being struck by\/against an object (n=10\u2009240, 12.9%) and transport-related injuries (n=1478, 1.9%). The prevalence of falls was 21% higher in infants (&lt;1 year, prevalence risk ratios (PRR)=1.21, 95%\u2009CI=1.19 to 1.23, p&lt;0.001) and 17% higher in toddlers (1\u20132 years, PRR=1.17, 1.15\u20131.19, p&lt;0.001) compared with preschoolers (3\u20135 years). Children primarily fell from beds (n=11\u2009208, 16.6%). Falls from beds were 3.49 (PRR=3.49, 95%\u2009CI=3.29 to 3.72, p&lt;0.001) times more common in infants and 1.34 (PRR=1.34, 95%\u2009CI=1.25 to 1.44, p&lt;0.001) times more common in toddlers versus preschoolers.
