Objective: Evidence from developing countries on the association between women’s endorsement of attitudes justifying partner abuse and their use of reproductive health services is suggestive but inconclusive. This study uses a nationally representative dataset from Lao PDR to provide strong evidence for the relationship between women’s endorsement of attitudes justifying partner abuse and use of reproductive health services.Methods: This study used data from the 2011–2012 Lao Social Indicator survey (LSIS). The analyses were performed on the responses of 4227 women. The exposure of interest in this study was endorsement of attitudes justifying partner abuse. Antenatal care (ANC) visits divided according to amount and quality, delivery care by type and place, and utilization of postnatal care (PNC) for mothers and newborn infants were used as representative outcome variables of reproductive health service utilization.Results: Approximately seven out of ten respondents (67.9%) believed that partner abuse was justified. Women who endorsed these attitudes were significantly less likely to receive any ANC, to seek institutional delivery, and to use trained medical personnel for delivery assistance. Endorsing attitudes were associated with reduced probability of receiving PNC services for mothers and newborn infants, reduced frequency of ANC visits, and receiving a fewer number of ANC components. Other sociodemographic factors likely to affect the increased utilization of several of the indicators of reproductive health care were living in the central region, belonging to the high bands of wealth, having higher level of education, being a young adult (20–34 years) or older (35–49 years), residing in urban areas, and being sexually empowered.Conclusions: In addition to a broad range of sociodemographic factors, our findings suggested that women’s endorsement of attitudes justifying partner abuse should be treated as an important psychosocial determinant of reproductive health care service utilization in Lao PDR.
