Based on the patriarchal gender role perspective, this study examines the associations between parenting practices and child mortality. Using the 2014 Cambodia Demographic and Health Survey consisting of 7,165 ever-married women (M=28.70 years old), the results showed that mothers’ and fathers’ level of involvement and nutritional feeding were lower in remarried/re-partnered households compared to those in first-time married and divorced households. Remarried/re-partnered families reported a higher number of deceased sons and daughters compared to their first-time married and divorced counterparts. Hierarchical linear regression analyses showed significant interaction effects between marital status and fathers’ involvement, indicating that the highest number of deceased sons was reported in remarried/re-partnered households with the lowest level of father involvement. Other predictors for deceased sons and daughters included lower socioeconomic status, older mothers and older fathers. Families with a larger number of children were more likely to report having a deceased son. This study contributes to our understanding of the challenges faced by remarried/re-partnered women and their children in Cambodia where the traditional patriarchal gender roles are enforced.
