Abstract

fetched live from OpenAlex

The association between family violence and the COVID-19 pandemic remains complex. This meta-analysis aimed to determine trends in the observed changes in family violence comparing the pre-pandemic period to the pandemic period. A systematic search was performed in electronic databases to identify all relevant research reporting on COVID-19 and family violence. There was a statistically significant increase in family violence after the first lockdown. The odds ratio for the prevalence of physical and sexual violence together was 7.24 (95% CI = 4.74, 11.03 p < 0.001). A small marginal increase in the prevalence of various types of family violence leading to hospitalization was found, however, the result was not statistically significant (OR = 1.91, 95% CI = 0.91, 3.96, p = 0.09). A small significant increase in the prevalence of victims with a perception of increased violence during the pandemic lockdown was observed (proportion = 33%, 95% CI = 15.72%, 50.34%, p = 0.002). This meta-analysis found that during the COVID-19 lockdown, there was an increase in the prevalence of overall family violence, a small, non-significant, increase in the prevalence of hospitalizations due to family violence, as well as an increase in the perception of family violence by victims. These results are clinically relevant for implementing effective measures of violence prevention to safeguard vulnerable populations.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
