Monthly Sulfadoxine-Pyrimethamine (SP) During Pregnancy
Women will be given SP (3 full strength tabs, 500 mg/25 mg) every four weeks times during pregnancy. In addition, placebos will be used to mimic the identical dosing strategy such that every 4 weeks women will receive two drugs on day 1 (SP and placebo or DP and placebo) followed by one drug on days 2 and 3 (DP or placebo). Two placebos will be used, one that mimics the appearance of SP and one that mimics the appearance of DP. Monthly Sulfadoxine-Pyrimethamine (SP) During Pregnancy
Monthly Dihydroartemisinin-Piperaquine (DP) During Pregnancy
Women will be given DP (3 full strength tabs, 40 mg/320 mg, given once a day for 3 consecutive days) every 4 weeks during pregnancy. In addition, placebos will be used to mimic the identical dosing strategy such that every 4 weeks women will receive two drugs on day 1 (SP and placebo or DP and placebo) followed by one drug on days 2 and 3 (DP or placebo). Two placebos will be used, one that mimics the appearance of SP and one that mimics the appearance of DP. Monthly Dihydroartemisinin-Piperaquine (DP) During Pregnancy

Defined as the proportion with hemoglobin \< 10 g/dL measure routinely at 12, 28, and 52 weeks of age. Number of cases per person year (PPY). This is a prevalence measure but are repeated measures during infancy. In other words we measured this outcome up to 3 times for each participant during infancy (at 12, 28 and 52 weeks of age).
