Changes in child maltreatment occurrence during the COVID-19 pandemic: A systematic review

BACKGROUND: Child maltreatment (CM) is an important public health issue. During the COVID-19 pandemic, there was widespread concern that CM risk factors were exacerbated while opportunities to seek support were reduced, potentially impacting occurrences of CM. OBJECTIVE: To synthesize evidence evaluating changes in CM outcomes during the COVID-19 pandemic compared to pre-pandemic. PARTICIPANTS AND SETTING: Individuals ≤18 years old living in member countries of the Organization for Economic Co-operation and Development. METHODS: We conducted a systematic review of primary studies identified in multiple databases. Independent reviewers screened titles/abstracts and full texts. Moderate to low risk of bias studies were synthesized using frequency counts to categorize CM outcomes as having increased, decreased, or not changed from pre- to during the pandemic. These were used to develop narrative statements, which underwent assessment for certainty in the evidence. RESULTS: We included 71 studies. Most CM outcomes relied on administrative data and showed mixed findings across the categories. Overall, there was likely no change in emotional neglect (moderate certainty), and may have been an increase in neglect (low certainty) and exposure to intimate partner violence (very low certainty). Changes in physical, sexual, and psychological abuse and any CM were very uncertain. DISCUSSION: The evidence informing changes in CM from before to during the COVID-19 pandemic is mixed and very uncertain for most outcomes, underpinned by gaps in the CM data collection systems during the pandemic period. Efforts to strengthen CM data and surveillance systems could improve preparedness for future pandemic situations.
