Abstract

ABSTRACT: BACKGROUND: There are growing concerns regarding inequities in health, with poverty being an important determinant of health, as well as a product of health status. Within the People's Republic of China (P.R. China), disparities in socio-economic position are apparent, with the rural-urban gap of particular concern. Our aim was to compare direct and proxy methods of estimating household wealth in a rural and a peri-urban setting of Hunan province, P.R. China. METHODS: We collected data on ownership of household durable assets, housing characteristics and utility and sanitation variables in two village-wide surveys in Hunan province. We employed principal components analysis (PCA) and principal axis factoring (PAF) to generate household asset-based proxy wealth indices. Households were grouped into quartiles, from 'most wealthy' to 'most poor'. We compared the estimated household wealth for each approach. Asset-based proxy wealth indices were compared to those based on self-reported average annual income and savings at the household level. RESULTS: Spearman rank correlation analysis revealed that PCA and PAF yielded similar results, indicating that either approach may be used for estimating household wealth. Both indices were significantly associated with self-reported average annual income and combined income and savings, but not with savings alone, in both settings investigated. However, low correlation coefficients between the proxy and direct measures of wealth indicated that they are not complementary. We found wide disparities in ownership of household durable assets, and utility and sanitation variables, within and between settings. CONCLUSION: PCA and PAF yielded almost identical results and generated robust proxy wealth indices and categories. Pooled data from the rural and peri-urban settings highlighted structural differences in wealth, most likely a result of localised urbanization and modernization. Further research is needed to improve RESULTS: Spearman rank correlation analysis revealed that PCA and PAF yielded similar results, indicating that either approach may be used for estimating household wealth.
