Associations between independent variables, all anemia, and moderate anemia^*

Variable	Any anemia† (N = 165)	Only moderate anemia‡ (N = 65)
	OR (95% CI)	OR (95% CI)
Age (years)	1.00 (0.96, 1.05)	0.97 (0.90, 1.04)
Parity	1.09 (0.88, 1.34)	1.11 (0.83, 1.47)
Household size	1.04 (0.92, 1.17)	1.12 (0.95, 1.32)
Gestation (weeks)	1.07 (0.98, 1.16)	1.02 (0.91, 1.15)
Water source (ref: non-improved)§	0.55 (0.30, 1.00)	1.23 (0.49, 3.11)
Taking IFA	1.07 (0.64, 1.79)	0.92 (0.45, 1.89)
Toilet type (ref: non-improved)∥	0.81 (0.54, 1.22)	0.35 (0.18, 0.68)

CI = confidence interval; Hb = hemoglobin; IFA = iron and folic acid; OR = odds ratio.

^*Categorical reference variables: non-improved (untreated) water source, not taking IFA, and non-improved sanitation facility. Continuous variables: parity and household size.

^†Hb < 110 g/L.

^‡Hb = 70–99 g/L; excluding those women with no anemia, mild or severe anemia.

^§Improved: treated water supply; non-improved: untreated water supply.

^∥Improved: closed pit latrine; non-improved: open defecation.
