Association between personally attending a farmer-training workshop and knowledge or behavior regarding Taenia solium and after controlling for gender, age, and level of education in small-holder pig farmers who were interviewed 3 times in Western Kenya, 2006–2008^*

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
Busia only (N = 75)
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
	3	NS	OR = 4.3 [0.9–19.2] P = 0.061‡	NS	OR = 9.1 [1.8–47.3] P = 0.009
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.
