Stool samples from 880 residents in an urban slum in Dhaka, Bangladesh
, were collected on 3 occasions over one year, and examined for intest
inal parasites. Information on many potential risk factors for infecti
on was obtained by questionnaire from a respondent in each household s
tudied. In a crude univariate analysis of the data, several of the fac
tors were found to be significantly associated with Strongyloides ster
coralis infection. Most of these factors were co-variate with one anot
her, and with poverty generally. Using Mantel-Haenszel chi(2) tests to
control for confounding effects of each variable individually, the fo
llowing 4 factors remained independently associated with S. stercorali
s infection: respondent's use of a community latrine rather than a pri
vate latrine, living in a house with an earth floor rather than a ceme
nt floor, being of Bihari ethnicity, and being 7-10 years of age. Impl
ications of these results for the epidemiology and control of strongyl
oidiasis are briefly discussed.
