Maternal hemoglobin values at first booking in women diagnosed as anemic (moderate/severe and mild), normal or erythrocytic at second hemoglobin measurement*.

Altitude (sample)	Maternal hemoglobin (g/dL) at first booking
	Moderate/severe*		Mild*		Normal (Hb: 11–14.5 g/dL)*		Hb > 14.5 g/dL*
	X ± SD		X ± SD		X ± SD		X ± SD
Total (89,294)	12.10	0.84	12.10	0.82	12.50	0.91	13.19	0.86
Low (57,231)	11.99	0.77	12.02	0.77	12.22	0.81	12.51	0.87
Moderate (11,349)	12.55	0.87	12.47	0.93	12.74	0.89	13.06	0.86
High (20,714)	12.66	0.94	12.70	0.94	13.03	0.87	13.33	0.81

ANOVA one way. P < 0.05 except moderate/severe anaemia: moderate altitude versus high altitude P = 0.293.
