Abstract

Abstract.

The association of wealth and infections with , , , and microsporidia were examined in a longitudinal cohort conducted in Peru from 2001 to 2006. Data from 492 participants were daily clinical manifestations, weekly copro-parasitological diagnosis, and housing characteristics and assets owned (48 variables), and these data were used to construct a global wealth index using principal component analysis. Data were analyzed using continuous and categorical (wealth tertiles) models. Participant's mean age was 3.43 years (range = 0–12 years), with average follow-up of 993 days. Univariate and multivariate analyses identified significant associations between wealth and infections with and microsporidia. Participants with greater wealth indexes were associated with protection against ( < 0.001) and persistent infections (> 14 days). For microsporidia, greater wealth was protective ( = 0.066 continuous and = 0.042 by tertiles). Contrarily, infections with and were independent of wealth. Thus, subtle differences in wealth may affect the frequency of specific parasitic infections within low-income communities.
