The association of living conditions and lifestyle factors with burden of cysts among neurocysticercosis patients in Ecuador

Abstract:

We used baseline data on 154 symptomatic neurocysticercosis (NCC) patients in Ecuador to identify pbkp_redictors of the burden of cysts. We ran logistic regression models with the burden of cysts as the outcome, defined as the number of cysts in the brain (1 vs >1), and having cysts in all 3 phases of evolution (active, transitional and calcifications) vs <3. These two outcomes are thought to be indicators of exposure dose and/or repeated exposure over time. The pbkp_redictors examined were: living in a rural area, living on a dirt road, living in an adobe or wood house (vs brick/cement), no running water in the house, no bathroom in the house, having a domestic employee cook in the home, eating most meals at restaurants or street vendors, working in a manual labour job.We found that the odds of having multiple NCC cysts was higher among those working in manual labour (OR=3.5, p=0.004), and those who ate most meals outside the home had higher odds of having cysts in all 3 phases (OR=5.0, p=0.007). Burden of cysts may be a useful outcome when looking to identify exposure risk factors in the absence of an uninfected control group. © 2012 Royal Society of Tropical Medicine and Hygiene.
