Understanding the Relation between Short Birth Spacing and Child Maltreatment: Are Associations Due to Parental History of Childhood Abuse and Neglect?

Existing literature documents connections between short birth spacing (birth-to-conception interval of under 18 months) and the risk of child maltreatment, but explanations for this relation are understudied. We hypothesise that short birth spacing predicts child maltreatment, and it mediates the association between maternal history of childhood maltreatment and their child's risk of abuse and neglect. We use data for second and higher parity children from the Prospective Study of Infant Development (n = 335) and fit logistic regression models with relevant covariates to examine the association between maternal history of childhood maltreatment, her offspring's short birth spacing and her offspring's child maltreatment (CM) as measured by Child Protective Services (CPS) assessments. Findings demonstrate that children of mothers who reported experiencing any abuse or neglect during childhood have a higher likelihood of being born shortly spaced and a higher likelihood of CM. Additionally, short birth spacing is associated with increased likelihood of CM. No evidence for mediation from maternal history of maltreatment to CM operating through short birth spacing was detected. We conclude that maternal history of childhood maltreatment and short birth spacing are independent, additive factors for CM risk.
