¹n = 1594 for all models. Subjects with C-reactive protein concentrations >10 mg/L were excluded. The following variables were evaluated but did not enter into the models (P > 0.1): smoking, oral contraceptive use, alcohol consumption, highest grade of school completed, household income, household assets, home ownership, urbanicity, BMI, household density, toilet type, and water source.

²P < 0.01.

³P < 0.05.

⁴P < 0.001.

⁵P < 0.10.
