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\u201312 years), with average follow-up of 993 days. Univariate and multivariate analyses identified significant associations between wealth and infections with <jats:italic>Giardia<\/jats:italic> and microsporidia. Participants with greater wealth indexes were associated with protection against <jats:italic>Giardia<\/jats:italic> (<jats:italic>P<\/jats:italic> &lt; 0.001) and persistent <jats:italic>Giardia<\/jats:italic> infections (&gt; 14 days). For microsporidia, greater wealth was protective (<jats:italic>P<\/jats:italic> = 0.066 continuous and <jats:italic>P<\/jats:italic> = 0.042 by tertiles). Contrarily, infections with <jats:italic>Cryptosporidium<\/jats:italic> and <jats:italic>Cyclospora<\/jats:italic> were independent of wealth. Thus, subtle differences in wealth may affect the frequency of specific parasitic infections within low-income communities.<\/jats:p>","DOI":"10.4269\/ajtmh.2011.10-0442","type":"journal-article","created":{"date-parts":[[2011,1,6]],"date-time":"2011-01-06T16:27:08Z","timestamp":1294331228000},"page":"38-42","source":"Crossref","is-referenced-by-count":28,"title":["Wealth
