One-year mortality disparities between infants of unmarried and married families in South Korea: a large scale retrospective cohort study.

ABSTRACT:

Background

This study examined disparities in 1-year mortality rates between infants born to married and unmarried single-parent families, emphasizing the need for targeted health policies.

Methods

Data from 3,298,263 cases, obtained from the South Korea National Statistical Office (2010-2017), were analyzed. T-tests and chi-square tests were used to assess the demographic characteristics of the study group. The number of deaths per 1,000 live births was calculated, and logistic and multivariable logistic regressions were employed to compare infant mortality rates between family types. Additional stratified analyses, based on gestational age and birth weight, further elucidated the relationship between parental marital status and infant mortality.
