The Reciprocal Relationship between Instrumental Support from Children and Self-Rated Health among Older Adults over Time in Rural China.

Objective: To investigate the dynamic interplay between instrumental support from children and self-rated health (SRH) among older adults over time in rural China. Methods: Data came from a regional representative, longitudinal study The Well-Being of Older People in Anhui Province collected in 2001, 2003, 2006, 2009, and 2012. At baseline, 1636 respondents reported having at least one child. Bivariate latent change score modeling was conducted, and sequential model comparison was used to assess the directionality of the reciprocal association. Results: Older adults who received higher levels of help with household chores from children tended to experience improvement in subsequent SRH, irrespective of gender. There is no evidence to support the influence of SRH on subsequent changes in instrumental support. Discussion: This study sheds light on the sequence of changes between support and health processes using population-based data within a specific sociocultural context.
