Risk factors for xerophthalmia among mothers and their children and for mother-child pairs with xerophthalmia in Cambodia.

Objective: To characterize the risk of xerophthalmia among nonpregnant women and their children and the risk factors for households in which both mother and child have xerophthalmia.

Methods: In case-control analyses of more than 15 000 households in the National Micronutrient Survey of Cambodia, univariate and multivariate logistic regression were used to estimate odds ratios (ORs) for nonpregnant mothers, children, and mother-child pairs with xerophthalmia.

Main Outcome Measures: Risk factors for xerophthalmia.
