Longitudinal correlation between poverty and mental health trajectories among low-income populations in China: a group-based dual trajectory model analysis

Abstract

ABSTRACT This study aims to explore the long-term correlations between poverty and depression among low-income Chinese people. We utilise data from the China Family Panel Study 2010–2018. A group-based dual trajectory model was employed to examine the relationship between poverty and depression trajectories. The results indicate a bi-directional relationship between the distribution of poverty and depression. Moreover, there is a diversity of dynamics associated with poverty and depression. Furthermore, a stronger influence of depression on poverty changes in the interactive relationship. These findings suggest the need to develop targeted policy programmes based on the characteristics of poverty and depression trajectory patterns.
