Note. OR = odds ratio; CI = confidence interval; AOR = adjusted odds ratio.
Adjusted for socioeconomic strata, mother's education, level of hygiene knowledge, attitudes toward hand washing, perceived level of control, and subjective social norms about hand washing.
Level of knowledge was assessed on the basis of the number of correct responses to 4 questions. High (4), medium (3), and low (1–2).
Perceived level of control was assessed with 2 questions. Respondents who answered “easy” or “very easy” to both questions were classified as having a high degree (1); all others were classified as having a low degree (0).
Attitudes toward proper hand washing were assessed on the basis of 3 questions. Each question was scored on a 5-point scale, and the cumulative scale was recoded as negative (3–6), neutral (7–11), and positive (12–15).
Perceived social norms of hand washing were measured with two questions. Each question was scored on a 5-point scale and recoded as negative (2–5), neutral (6–7), and positive (8–10).
