The multifaceted nature of poverty and differential trajectories of health among children

The relationships between poverty and children’s health have been well documented, but the diverse and dynamic nature of poverty has not been thoroughly explored. Drawing on cumulative disadvantage and human capital theory, we examined to what extent the duration and depth of poverty, as well as the level of material hardship, affected changes in physical health among children over time. Data came from eight waves of the Korea Welfare Panel Study between 2006 and 2013. Using children who were under age 10 at baseline (N = 1657, Observations = 13,256), we conducted random coefficient regression in a multilevel growth curve framework to examine poverty group differences in intra-individual change in health status. Results showed that chronically poor children were most likely to have poor health. Children in households located far below the poverty line were most likely to be in poor health at baseline, while near-poor children’s health got significantly worse over time. Material hardship also had a significant impact on child health.
