Abstract

Studies have identified correlates of intimate partner violence (IPV) during pregnancy at the individual and neighborhood levels, but have used inconsistent definitions of IPV. We aimed to compare correlates based on two IPV definitions: broad (physical, sexual, or psychological violence) and narrow (physical or sexual violence only). Our analysis included 12,358 women in 2,110 census tracts (weighted to represent 269,671 women) who recently gave birth and responded to the Los Angeles Mommy and Baby (LAMB) survey. We linked 2007 and 2010 LAMB data to American Community Survey 2006–2010 census tract data, and conducted separate logistic multilevel analyses to identify correlates of IPV based on each definition. Prevalence of IPV during pregnancy was much higher by the broad (18.3 %) than the narrow definition (3.9 %). No independent neighborhood-level correlates were identified. Some individual-level correlates were associated with both IPV definitions, including substance abuse (OR 3.15, 95 % CI 2.47–4.00 for broad definition; OR 3.60, 95 % CI 2.30–5.64 for narrow definition) and medical problems (OR for ≥3 vs. 0 medical problems 2.03, 95 % CI 1.61–2.55 for broad definition, OR 2.40, 95 % CI 1.54–3.74 for narrow definition). Other correlates associated only with the broad definition, such as car accidents (OR 1.44, 95 % CI 1.04–2.00) and moving during pregnancy (OR 1.35, 95 % CI 1.12–1.62). Differences in correlates of IPV during pregnancy for a broad versus narrow IPV definition may illustrate the situations or mechanisms by which different types of IPV arise. Individual-level characteristics may outweigh neighborhood influences in a diverse population.
