A multi-level analysis of urban/rural and socioeconomic differences in functional health status transition among older Chinese.
The main purpose of the study is to assess urban versus rural differences in functional status transitions among older Chinese, aged 55+, and to examine how individual and community level socioeconomic indicators alter the rural/urban effects and themselves influence transitions. The study uses a hierarchical linear modeling approach that considers individual responses to be embedded within communities. Data come from the 2004 and 2006 rounds of the Chinese Health and Nutrition Survey. The study considers the functional transitions of 2944 individuals living across 209 communities in nine Chinese provinces. Functioning is measured at baseline as being able or not being able to conduct all of the following: walking, standing, climbing stairs, lifting, kneeling. Outcomes include having or not having a functional limitation, measured the same way, dying, or not responding. Outcomes are modeled adjusted for baseline functional status. Findings indicate urbanites have substantial advantages. They are less likely to have a limitation at follow-up and less likely to die over the study period. Some of this is explained by socioeconomic indicators measured at two levels. Cross-level interactions suggest education and having insurance operate differently in urban and rural areas. Community-level indicators are somewhat less predictive, and much of the urban advantage is unexplained. In conclusion, the study suggests differences in the influences of socioeconomic indicators in China versus what has been found in the past, and that place of residence in China is a particularly robust predictor of functional health transitions.
