Question Question-naire Multivariable logistic regression using backward elimination modeling technique
Attended personally Gender Age Level of education
Combined data from Kakamega and Busia (N = 131)
Have you heard of a disease in pigs where cysts are found in the pig's muscles? 2 OR = 4.1 [1.8–9.1] P = 0.001 NS NS NS
3 OR = 2.9 [1.2–6.7] P = 0.007 OR = 9.2 [1.2–72.7] P = 0.035 NS NS
Do you know how pigs get the disease? 2 OR = 2.5 [1.1–5.7] P = 0.034 NS NS NS
3 OR = 3.3 [1.5–7.3] P = 0.003 NS NS NS

Farmer was shown a picture of tapeworm segments. Have you ever seen these kinds of worms in someone's stool (feces)? 2 NS NS NS NS
3 NS NS OR = 0.6 [0.4–0.9] P = 0.019 NS
How do you think people get infected with these tapeworms? (Correct for T. solium parasite) 2 NS OR = 0.65 [0.1–3.5] P = 0.618 OR = 0.9 [0.5–1.4] P = 0.565 OR = 13.7 [3.1 = 61.0] P = 0.001

How do you think people get infected with these tapeworms? (Correct for Neurocysticercosis/epilepsy) 2 OR = 1.1 [0.3–3.4] P = 0.897 OR = 0.7 [0.2–2.7] P = 0.652 NS OR = 11.3 [1.3–97.8] P = 0.028
3 NS NS NS OR = 10.2 [1.3–81.3] P = 0.028
*

Includes only farmers who were matched between the second and third farmer visits.

Questionnaire 2 was administered in Busia Nov 2006 and in Kakamega Dec 2007 and May 2008; Questionnaire 3 was administered in Busia Feb 2007 and in Kakamega June and Oct 2008.

Although P > 0.05, the variable was kept in the model because of confounding. NS = not significant.
