AB/UTI = asymptomatic bacteriuria/urinary tract infection; GA = gestational age; hpf = high-power field; sqrt epg = square root transformed eggs per gram; VIF = variance inflation factor.

^*Variables entered in model: GA, presence of caries, scabies, and AB/UTI; amount of Lactobacillus; severity of Bacteroides/Gardnerella, Mobiluncus, vaginal trichomoniasis, yeast and diplococcal infection; hookworm and Trichuris epg. Overall model F_{4, 67} = 5.56; P = 0.0006; adjusted R² = 0.20; VIF = 1.58.

^†Coded as 0 = absent, 1 = present.

^‡Coded as 0 = absent; 1+ = 1/hpf; 2+ = 2/hpf; 3+ = 3/hpf; 4+ = 4 or more/hpf.

^§Coded as 0 = absent; 1+ = 1–5/hpf; 2+ = 6–10/hpf; 3+ = 11–20/hpf; 4+ = > 20/hpf.

^∥Variables entered in model: GA, presence of caries, scabies, and AB/UTI; amount of Lactobacillus; severity of Bacteroides/Gardnerella, Mobiluncus, vaginal trichomoniasis, yeast, and diplococcal infection; Ascaris and Trichuris epg. Overall model F_{3, 68} = 16.58; P < 0.0001; adjusted R² = 0.39; VIF = 1.01.

^**Variables entered in model: GA, presence of caries, scabies, and AB/UTI; amount of Lactobacillus; severity of Bacteroides/Gardnerella, Mobiluncus, vaginal trichomoniasis, yeast, and diplococcal infection; Ascaris and hookworm epg. Overall model F_{2, 69} = 49.45; P < 0.0001; adjusted R² = 0.58; VIF = 1.00.
