Also, along with international databases, national databases such as SID, Magiran, Medlib and Irandoc were searched.

Results: Data from 5 Meta- were entered. A significant relationship was found between abuse during pregnancy and Low birth weight (LBW) (odds ratios [OR] ranged from 2.11 to 1.18; five Meta-analysis), and preterm birth (PTB) (OR ranged from 1.21 to 1.91). According to one Meta-analysis, intimate partner violence (IPV)was statistically marginally associated with small-for-gestational-age (SGA) infants (OR: 1.37, 95% confidence interval [CI]: 1.02 to 1.84; Heterogeneity I2: 84%; I2: 32%), but there was not any relationship between IPV with Intrauterine growth restriction (IUGR) (P>0.05).
