Patel, Patricia L. Hibberd, Shivaprasad S. Goudar, Sangappa Dhaded, Richard J. Derman, Janet L. Moore, Elizabeth M. Mcclure, Robert L. Goldenberg

Community Health Sciences

Background: While the relationship between hemoglobin (Hb) concentrations and pregnancy outcomes has been studied often, most reports have focused on a specific Hb cutoff used to define anemia. Fewer studies have evaluated pregnancy outcomes across the entire range of Hb values. Moreover, to date, most studies of the relationship of Hb concentrations to pregnancy outcomes have been done in high-income countries. Thus, we have sought to determine the relationship between the range of maternal Hb concentrations and adverse birth outcomes among South Asian pregnant women.
Methods: For this study, we used data collected from two South Asian countries (Pakistan - …
