BACKGROUND: Abusive head trauma (AHT) is a leading cause of fatal maltreatment in infancy.
OBJECTIVE: To estimate the annual incidence of hospitalized AHT among infants in Japan from 2014 to 2022 and assess the impact of the COVID-19 pandemic and increasing male childcare-leave uptake.
PARTICIPANTS AND SETTING: Infants <1 year old admitted to hospitals participating in the nationwide Diagnosis Procedure Combination (DPC) database in Japan.
METHODS: We conducted a retrospective study identifying AHT admissions using ICD-10 codes, and calculated annual incidence using census data. We compared pre-COVID-19 (2014-2019) and COVID-19 (2020-2022) periods and examined the ecological association between AHT incidence and national male childcare-leave uptake.
RESULTS: We identified 755 presumptive and 5019 possible AHT admissions across 10.4 million infant-years. Presumptive AHT incidence was 7.9/100,000 in 2014 and 10.5/100,000 in 2022, demonstrating year-to-year variation but no significant overall trend (P for trend = 0.91). The incidence rate ratio for the COVID-19 period versus pre-COVID-19 was 0.95 (95% CI 0.81-1.12). No significant association was found between male childcare-leave uptake and AHT incidence (ρ = 0.15, P = 0.70).
CONCLUSIONS: Hospitalized AHT incidence in Japan did not change significantly over 9 years. At the population level, neither the COVID-19 pandemic nor the increased uptake of male childcare leave was associated with a measurable change in the AHT burden.
